The Command Line in 2004

The Command Line in 2004

In July 2004 I found myself sitting alone in the dark, on the enclosed deck of a ferry boat oozing between fog-shrouded islands of the Alaskan coast. The scenery was haunting, but after the first three hours, I decided to do occupy myself by finally reading Neal Stephenson's essay about the command-line. Halfway through it I began crossing things out, and scribbling comments in the margin. The essay was five years old, and in dire need of a fresh perspective.

Months later, I learned that Stephenson himself was dissatisfied with the essay. He wrote that it, "is now badly obsolete and probably needs a thorough revision." An "Ask Slashdot" poll quoted him as saying, "I keep meaning to update it, but if I'm honest with myself, I have to say this is unlikely."

Though I have fleshed out my original comments into longer, more structured pieces, it is not my intention to replace or revise Neal Stephenson's original writing. His original essay is a much more cohesive and entertaining read than my notes are. (He is a Writer, after all. I consider myself a code-monkey by comparison.) In fact, my notes do not hold together unless they use the original essay as a framework, and that's why his entire essay is reproduced here, with my comments color-coded. And yes, I have sought and obtained permission from Neal to do this.

In the Beginning was the Command Line

by Neal Stephenson

About twenty years ago Jobs and Wozniak, the founders of Apple, came up with the very strange idea of selling information processing machines for use in the home. The business took off, and its founders made a lot of money and received the credit they deserved for being daring visionaries. But around the same time, Bill Gates and Paul Allen came up with an idea even stranger and more fantastical: selling computer operating systems. This was much weirder than the idea of Jobs and Wozniak. A computer at least had some sort of physical reality to it. It came in a box, you could open it up and plug it in and watch lights blink. An operating system had no tangible incarnation at all. It arrived on a disk, of course, but the disk was, in effect, nothing more than the box that the OS came in. The product itself was a very long string of ones and zeroes that, when properly installed and coddled, gave you the ability to manipulate other very long strings of ones and zeroes. Even those few who actually understood what a computer operating system was were apt to think of it as a fantastically arcane engineering prodigy, like a breeder reactor or a U-2 spy plane, and not something that could ever be (in the parlance of high-tech) "productized."

Yet now the company that Gates and Allen founded is selling operating systems like Gillette sells razor blades. New releases of operating systems are launched as if they were Hollywood blockbusters, with celebrity endorsements, talk show appearances, and world tours. The market for them is vast enough that people worry about whether it has been monopolized by one company. Even the least technically-minded people in our society now have at least a hazy idea of what operating systems do; what is more, they have strong opinions about their relative merits. It is commonly understood, even by technically unsophisticated computer users, that if you have a piece of software that works on your Macintosh, and you move it over onto a Windows machine, it will not run. That this would, in fact, be a laughable and idiotic mistake, like nailing horseshoes to the tires of a Buick.

A person who went into a coma before Microsoft was founded, and woke up now, could pick up this morning's New York Times and understand everything in it--almost:

* Item: the richest man in the world made his fortune from-what? Railways? Shipping? Oil? No, operating systems.

* Item: the Department of Justice is tackling Microsoft's supposed OS monopoly with legal tools that were invented to restrain the power of Nineteenth-Century robber barons.

* Item: a woman friend of mine recently told me that she'd broken off a (hitherto) stimulating exchange of e-mail with a young man. At first he had seemed like such an intelligent and interesting guy, she said, but then "he started going all PC-versus-Mac on me."

What the hell is going on here? And does the operating system business have a future, or only a past? Here is my view, which is entirely subjective; but since I have spent a fair amount of time not only using, but programming, Macintoshes, Windows machines, Linux boxes and the BeOS, perhaps it is not so ill-informed as to be completely worthless. This is a subjective essay, more review than research paper, and so it might seem unfair or biased compared to the technical reviews you can find in PC magazines. But ever since the Mac came out, our operating systems have been based on metaphors, and anything with metaphors in it is fair game as far as I'm concerned.

MGBs, TANKS, AND BATMOBILES

Around the time that Jobs, Wozniak, Gates, and Allen were dreaming up these unlikely schemes, I was a teenager living in Ames, Iowa. One of my friends' dads had an old MGB sports car rusting away in his garage. Sometimes he would actually manage to get it running and then he would take us for a spin around the block, with a memorable look of wild youthful exhiliration on his face; to his worried passengers, he was a madman, stalling and backfiring around Ames, Iowa and eating the dust of rusty Gremlins and Pintos, but in his own mind he was Dustin Hoffman tooling across the Bay Bridge with the wind in his hair.

In retrospect, this was telling me two things about people's relationship to technology. One was that romance and image go a long way towards shaping their opinions. If you doubt it (and if you have a lot of spare time on your hands) just ask anyone who owns a Macintosh and who, on those grounds, imagines him- or herself to be a member of an oppressed minority group.

The other, somewhat subtler point, was that interface is very important. Sure, the MGB was a lousy car in almost every way that counted: balky, unreliable, underpowered. But it was fun to drive. It was responsive. Every pebble on the road was felt in the bones, every nuance in the pavement transmitted instantly to the driver's hands. He could listen to the engine and tell what was wrong with it. The steering responded immediately to commands from his hands. To us passengers it was a pointless exercise in going nowhere--about as interesting as peering over someone's shoulder while he punches numbers into a spreadsheet. But to the driver it was an experience. For a short time he was extending his body and his senses into a larger realm, and doing things that he couldn't do unassisted.

The analogy between cars and operating systems is not half bad, and so let me run with it for a moment, as a way of giving an executive summary of our situation today.

Imagine a crossroads where four competing auto dealerships are situated. One of them (Microsoft) is much, much bigger than the others. It started out years ago selling three-speed bicycles (MS-DOS); these were not perfect, but they worked, and when they broke you could easily fix them.

There was a competing bicycle dealership next door (Apple) that one day began selling motorized vehicles--expensive but attractively styled cars with their innards hermetically sealed, so that how they worked was something of a mystery.

The big dealership responded by rushing a moped upgrade kit (the original Windows) onto the market. This was a Rube Goldberg contraption that, when bolted onto a three-speed bicycle, enabled it to keep up, just barely, with Apple-cars. The users had to wear goggles and were always picking bugs out of their teeth while Apple owners sped along in hermetically sealed comfort, sneering out the windows. But the Micro-mopeds were cheap, and easy to fix compared with the Apple-cars, and their market share waxed.

Eventually the big dealership came out with a full-fledged car: a colossal station wagon (Windows 95). It had all the aesthetic appeal of a Soviet worker housing block, it leaked oil and blew gaskets, and it was an enormous success. A little later, they also came out with a hulking off-road vehicle intended for industrial users (Windows NT) which was no more beautiful than the station wagon, and only a little more reliable.

Since then there has been a lot of noise and shouting, but little has changed. The smaller dealership continues to sell sleek Euro-styled sedans and to spend a lot of money on advertising campaigns. They have had GOING OUT OF BUSINESS! signs taped up in their windows for so long that they have gotten all yellow and curly. The big one keeps making bigger and bigger station wagons and ORVs.

Now, things have changed. The Microsoft station wagons are no longer crash prone. Their cars and off-roaders merged into one vehicle, and they've diversified with boats and planes (A Tablet OS, the XBOX). The Apple-cars are no longer hermetically sealed. The "going out of business" signs are coming down.

On the other side of the road are two competitors that have come along more recently.

One of them (Be, Inc.) is selling fully operational Batmobiles (the BeOS). They are more beautiful and stylish even than the Euro-sedans, better designed, more technologically advanced, and at least as reliable as anything else on the market--and yet cheaper than the others.

BeOS is a beautiful operating system, but whether we're UNIX, Linux, BeOs, or Apple users - we're still all basically PWN3D by Microsoft. Five years since this essay hasn't changed that.

With one exception, that is: Linux, which is right next door, and which is not a business at all. It's a bunch of RVs, yurts, tepees, and geodesic domes set up in a field and organized by consensus. The people who live there are making tanks. These are not old-fashioned, cast-iron Soviet tanks; these are more like the M1 tanks of the U.S. Army, made of space-age materials and jammed with sophisticated technology from one end to the other. But they are better than Army tanks. They've been modified in such a way that they never, ever break down, are light and maneuverable enough to use on ordinary streets, and use no more fuel than a subcompact car. These tanks are being cranked out, on the spot, at a terrific pace, and a vast number of them are lined up along the edge of the road with keys in the ignition. Anyone who wants can simply climb into one and drive it away for free.

New users of Linux are almost always exposed to it through a member of the userbase, insuring that they have at least one person on-hand who can answer their inevitable questions and undo their horrible mistakes. The above is a romanticized description of the Linux experience, because it implies that the ubiquitous Linux veteran is not a factor. Unfortunately, Linux was not designed for end-to-end ease of use -- in that respect, it was not "designed" at all.

Today, the above description is actually what it would be like if OS X were released as open-source, ran flawlessly on all equipment, and was renamed Linux. And yes, now my personal bias is exposed. Better to expose it early and up front.

Customers come to this crossroads in throngs, day and night. Ninety percent of them go straight to the biggest dealership and buy station wagons or off-road vehicles. They do not even look at the other dealerships.

Of the remaining ten percent, most go and buy a sleek Euro-sedan, pausing only to turn up their noses at the philistines going to buy the station wagons and ORVs. If they even notice the people on the opposite side of the road, selling the cheaper, technically superior vehicles, these customers deride them cranks and half-wits.

The Batmobile outlet sells a few vehicles to the occasional car nut who wants a second vehicle to go with his station wagon, but seems to accept, at least for now, that it's a fringe player.

The group giving away the free tanks only stays alive because it is staffed by volunteers, who are lined up at the edge of the street with bullhorns, trying to draw customers' attention to this incredible situation. A typical conversation goes something like this:

Hacker with bullhorn: "Save your money! Accept one of our free tanks! It is invulnerable, and can drive across rocks and swamps at ninety miles an hour while getting a hundred miles to the gallon!"

Prospective station wagon buyer: "I know what you say is true...but...er...I don't know how to maintain a tank!"

Bullhorn: "You don't know how to maintain a station wagon either!"

Buyer: "But this dealership has mechanics on staff. If something goes wrong with my station wagon, I can take a day off work, bring it here, and pay them to work on it while I sit in the waiting room for hours, listening to elevator music."

Bullhorn: "But if you accept one of our free tanks we will send volunteers to your house to fix it for free while you sleep!"

Buyer: "Stay away from my house, you freak!"

Bullhorn: "But..."

Buyer: "Can't you see that everyone is buying station wagons?"

This is a metaphor with legs. However, it has one flaw that needs addressing: Windows and Linux are software, and Apple is a hardware company. This problem can be solved like many other problems are solved in the computer industry: By adding monkeys.

No, seriously. It works like this. Computer hardware has changed immeasurably in the last 30 years, and nowadays everything we do must be guided by an operating system. To illustrate that situtation with cars, I could say that all modern cars are so fancy and complicated that each one sold comes with a chauffeur who will do the driving for you.

For example, if you buy an Apple sedan, you also receive a little monkey in a snappy blue suit. Your personal X-Monkey (as the company calls him) is the ideal driver of your Apple sedan. He knows where everything is, feeds and washes himself, drives defensively, and will even tune up the car for you. X-Monkey will accept precise instructions like, "forward 10 feet, right 20 degrees", but he is smart enough to think on his own, so you can tell him "Drive me to a taco stand, then pick up Uncle Steve". He will also keep you out of trouble, by politely ignoring instructions like, "Run over that jogger", and "Floor it", when you're at a red light. Depending on your temperament, this could actually be a downside.

The X-Monkey comes from a line of monkeys originally bred by the military for the purpose of driving tanks. It's a good fit, because the modern Apple sedan is actually a tank in a fancy shell. The X-Monkey's only drawback is that he can only drive a car from Apple. Show him any other vehicle, and he won't even know how to operate the door lock.

Meanwhile, the free-thinking Linux people, displeased with genetic engineering, have created their own smart monkey chauffeurs through a massive international breeding program. Unlike the X-Monkey, the Linux Monkey is capable of driving any car, including the Apple sedan. If you could install a steering wheel on a log splitter, the Linux Monkey could drive it for you. The catch is, you have to train the Linux Monkey yourself. Fortunately there are experts everywhere who will help you out, and the Linux Monkey trains easily.

The Microsoft Gorilla, on the other hand, cannot be trained. Instead, you must keep rephrasing your directions until the MS Gorilla can comprehend them. He consumes both front seats, lowering the mileage of your car, and blocking most of your view. Though he sounds like a bad deal, MS Gorilla is actually extremely popular, because he looks impressive, drives aggressively, and keeps his mouth shut. If you speak in his limited vocabulary, he will take you Where You Want To Go Today ... especially if he can plow monkeys off the intervening road. However, if you touch anything on the dashboard, or try to haggle with him over the exact route, he may become irritated and casually drive your car into a telephone pole. People learn to not argue.

The point to this altered metaphor is that the Microsoft dealership, and the Linux collective, do not really make cars at all. All those shiny automobiles sitting on the lot and lined up on the street corner are re-branded vehicles, manufactured by other companies. However, their modern instrument panels are so confusing that they'd be useless without a chauffeur. ... And the Microsoft dealership gets a cut from the price of every vehicle that leaves their lot, piloted by the Microsoft Gorilla.

If you were so inclined, you could purchase a car from them, drive to the sidewalk, and kick the gorilla out onto the curb. The Linux Monkey can hop right in and start driving for you. Of course, Microsoft already has your money, and what are you going to do with a spare gorilla?

Contrast this with the Apple dealership, that personally designs and assembles every Apple sedan. When a sedan leaves their lot, they pocket the whole amount. You could still kick out the X-Monkey any time, but why would you? The Linux Monkey is basically the same, without the training.

BIT-FLINGER

The connection between cars, and ways of interacting with computers, wouldn't have occurred to me at the time I was being taken for rides in that MGB. I had signed up to take a computer programming class at Ames High School. After a few introductory lectures, we students were granted admission into a tiny room containing a teletype, a telephone, and an old-fashioned modem consisting of a metal box with a pair of rubber cups on the top (note: many readers, making their way through that last sentence, probably felt an initial pang of dread that this essay was about to turn into a tedious, codgerly reminiscence about how tough we had it back in the old days; rest assured that I am actually positioning my pieces on the chessboard, as it were, in preparation to make a point about truly hip and up-to-the minute topics like Open Source Software). The teletype was exactly the same sort of machine that had been used, for decades, to send and receive telegrams. It was basically a loud typewriter that could only produce UPPERCASE LETTERS. Mounted to one side of it was a smaller machine with a long reel of paper tape on it, and a clear plastic hopper underneath.

In order to connect this device (which was not a computer at all) to the Iowa State University mainframe across town, you would pick up the phone, dial the computer's number, listen for strange noises, and then slam the handset down into the rubber cups. If your aim was true, one would wrap its neoprene lips around the earpiece and the other around the mouthpiece, consummating a kind of informational soixante-neuf. The teletype would shudder as it was possessed by the spirit of the distant mainframe, and begin to hammer out cryptic messages.

Since computer time was a scarce resource, we used a sort of batch processing technique. Before dialing the phone, we would turn on the tape puncher (a subsidiary machine bolted to the side of the teletype) and type in our programs. Each time we depressed a key, the teletype would bash out a letter on the paper in front of us, so we could read what we'd typed; but at the same time it would convert the letter into a set of eight binary digits, or bits, and punch a corresponding pattern of holes across the width of a paper tape. The tiny disks of paper knocked out of the tape would flutter down into the clear plastic hopper, which would slowly fill up what can only be described as actual bits. On the last day of the school year, the smartest kid in the class (not me) jumped out from behind his desk and flung several quarts of these bits over the head of our teacher, like confetti, as a sort of semi-affectionate practical joke. The image of this man sitting there, gripped in the opening stages of an atavistic fight-or-flight reaction, with millions of bits (megabytes) sifting down out of his hair and into his nostrils and mouth, his face gradually turning purple as he built up to an explosion, is the single most memorable scene from my formal education.

Anyway, it will have been obvious that my interaction with the computer was of an extremely formal nature, being sharply divided up into different phases, viz.: (1) sitting at home with paper and pencil, miles and miles from any computer, I would think very, very hard about what I wanted the computer to do, and translate my intentions into a computer language--a series of alphanumeric symbols on a page. (2) I would carry this across a sort of informational cordon sanitaire (three miles of snowdrifts) to school and type those letters into a machine--not a computer--which would convert the symbols into binary numbers and record them visibly on a tape. (3) Then, through the rubber-cup modem, I would cause those numbers to be sent to the university mainframe, which would (4) do arithmetic on them and send different numbers back to the teletype. (5) The teletype would convert these numbers back into letters and hammer them out on a page and (6) I, watching, would construe the letters as meaningful symbols.

The division of responsibilities implied by all of this is admirably clean: computers do arithmetic on bits of information. Humans construe the bits as meaningful symbols. But this distinction is now being blurred, or at least complicated, by the advent of modern operating systems that use, and frequently abuse, the power of metaphor to make computers accessible to a larger audience. Along the way--possibly because of those metaphors, which make an operating system a sort of work of art--people start to get emotional, and grow attached to pieces of software in the way that my friend's dad did to his MGB.

People who have only interacted with computers through graphical user interfaces like the MacOS or Windows--which is to say, almost everyone who has ever used a computer--may have been startled, or at least bemused, to hear about the telegraph machine that I used to communicate with a computer in 1973. But there was, and is, a good reason for using this particular kind of technology. Human beings have various ways of communicating to each other, such as music, art, dance, and facial expressions, but some of these are more amenable than others to being expressed as strings of symbols. Written language is the easiest of all, because, of course, it consists of strings of symbols to begin with. If the symbols happen to belong to a phonetic alphabet (as opposed to, say, ideograms), converting them into bits is a trivial procedure, and one that was nailed, technologically, in the early nineteenth century, with the introduction of Morse code and other forms of telegraphy.

We had a human/computer interface a hundred years before we had computers. When computers came into being around the time of the Second World War, humans, quite naturally, communicated with them by simply grafting them on to the already-existing technologies for translating letters into bits and vice versa: teletypes and punch card machines.

These embodied two fundamentally different approaches to computing. When you were using cards, you'd punch a whole stack of them and run them through the reader all at once, which was called batch processing. You could also do batch processing with a teletype, as I have already described, by using the paper tape reader, and we were certainly encouraged to use this approach when I was in high school. But--though efforts were made to keep us unaware of this--the teletype could do something that the card reader could not. On the teletype, once the modem link was established, you could just type in a line and hit the return key. The teletype would send that line to the computer, which might or might not respond with some lines of its own, which the teletype would hammer out--producing, over time, a transcript of your exchange with the machine. This way of doing it did not even have a name at the time, but when, much later, an alternative became available, it was retroactively dubbed the Command Line Interface.

When I moved on to college, I did my computing in large, stifling rooms where scores of students would sit in front of slightly updated versions of the same machines and write computer programs: these used dot-matrix printing mechanisms, but were (from the computer's point of view) identical to the old teletypes. By that point, computers were better at time-sharing--that is, mainframes were still mainframes, but they were better at communicating with a large number of terminals at once. Consequently, it was no longer necessary to use batch processing. Card readers were shoved out into hallways and boiler rooms, and batch processing became a nerds-only kind of thing, and consequently took on a certain eldritch flavor among those of us who even knew it existed. We were all off the Batch, and on the Command Line, interface now--my very first shift in operating system paradigms, if only I'd known it.

A huge stack of accordion-fold paper sat on the floor underneath each one of these glorified teletypes, and miles of paper shuddered through their platens. Almost all of this paper was thrown away or recycled without ever having been touched by ink--an ecological atrocity so glaring that those machines soon replaced by video terminals--so-called "glass teletypes"--which were quieter and didn't waste paper. Again, though, from the computer's point of view these were indistinguishable from World War II-era teletype machines. In effect we still used Victorian technology to communicate with computers until about 1984, when the Macintosh was introduced with its Graphical User Interface. Even after that, the Command Line continued to exist as an underlying stratum--a sort of brainstem reflex--of many modern computer systems all through the heyday of Graphical User Interfaces, or GUIs as I will call them from now on.

As it still does, thank goodness.

GUIs

Now the first job that any coder needs to do when writing a new piece of software is to figure out how to take the information that is being worked with (in a graphics program, an image; in a spreadsheet, a grid of numbers) and turn it into a linear string of bytes. These strings of bytes are commonly called files or (somewhat more hiply) streams. They are to telegrams what modern humans are to Cro-Magnon man, which is to say the same thing under a different name. All that you see on your computer screen--your Tomb Raider, your digitized voice mail messages, faxes, and word processing documents written in thirty-seven different typefaces--is still, from the computer's point of view, just like telegrams, except much longer, and demanding of more arithmetic.

The quickest way to get a taste of this is to fire up your web browser, visit a site, and then select the View/Document Source menu item. You will get a bunch of computer code that looks something like this:

This crud is called HTML (HyperText Markup Language) and it is basically a very simple programming language instructing your web browser how to draw a page on a screen. Anyone can learn HTML and many people do. The important thing is that no matter what splendid multimedia web pages they might represent, HTML files are just telegrams.

When Ronald Reagan was a radio announcer, he used to call baseball games by reading the terse descriptions that trickled in over the telegraph wire and were printed out on a paper tape. He would sit there, all by himself in a padded room with a microphone, and the paper tape would eke out of the machine and crawl over the palm of his hand printed with cryptic abbreviations. If the count went to three and two, Reagan would describe the scene as he saw it in his mind's eye: "The brawny left-hander steps out of the batter's box to wipe the sweat from his brow. The umpire steps forward to sweep the dirt from home plate." and so on. When the cryptogram on the paper tape announced a base hit, he would whack the edge of the table with a pencil, creating a little sound effect, and describe the arc of the ball as if he could actually see it. His listeners, many of whom presumably thought that Reagan was actually at the ballpark watching the game, would reconstruct the scene in their minds according to his descriptions.

This is exactly how the World Wide Web works: the HTML files are the pithy description on the paper tape, and your Web browser is Ronald Reagan. The same is true of Graphical User Interfaces in general.

So an OS is a stack of metaphors and abstractions that stands between you and the telegrams, and embodying various tricks the programmer used to convert the information you're working with--be it images, e-mail messages, movies, or word processing documents--into the necklaces of bytes that are the only things computers know how to work with. When we used actual telegraph equipment (teletypes) or their higher-tech substitutes ("glass teletypes," or the MS-DOS command line) to work with our computers, we were very close to the bottom of that stack. When we use most modern operating systems, though, our interaction with the machine is heavily mediated. Everything we do is interpreted and translated time and again as it works its way down through all of the metaphors and abstractions.

This conveys a good impression of how complex our operating systems have become, but it also implies that the hardware itself, the physical object that we call a computer, has changed relatively little.

Computer-like circuitry has burrowed its way into almost every kind of device, in every arena of human progress. The microchip embedded in a rice cooker, for example, could potentially respond to a command-line interface. We could wire a teletype to most of the appliances we use in a day. But when someone says, "Use the computer!", the image that pops into our collective imagination is relatively well defined.

Consider the garden-variety machine from Dell. We pry open the cardboard box, wrestle the styrofoam jaws apart, and dump the thing on a tabletop. "There!" we say. "A brand-new computer!" But by the historical definition, we're actually looking at dozens of computers. A heap of computers. A computing collective.

Here's an abridged list of items inside the Dell machine that could be computers in their own right:

* The CPU

* The cache manager inside the CPU

* The on-board sound chip

* The USB controller

* The power-management system

* The network controller

* The graphics CPU

* The hard-drive controller

* The microcontroller inside the hard drive

* The settings-management CPU inside the display

* The key encoder inside the keyboard

Clearly a PC has become something more than a teletype. It has not just evolved from its ancestors, but actually contains multiple copies of its ancestors. If we wanted to treat a modern PC like a teletype, we would have to ignore all but one of these embedded computers, and throw the mouse, printer, disk drives, speakers, and game controllers in the trash can.

But we don't call our new Dell machine a "computing collective". We consider it one device, with a singular name. And our concept of an "Operating System" has evolved right along, neatly obscuring this complexity. The ways that we interact with a computer have always been simple -- punch buttons, move lumps on tabletops, occasionally shout and kick parts of it -- and any claim we had to a non-conceptual "closeness" with the processing itself died out around the time mechanical relays were replaced with transistors. That's why Mr. Stephenson is invoking the metaphor of telegrams. He is describing the quality of our relationship to the digital information that we wish to manipulate.

But that means that the crucial separation here is not between the computer (hardware) and the Operating System (software). Those are so deeply integrated these days that they have effectively merged into the same beast. The crucial division is between ourselves, and our information. And how that division is elucidated by the computer, with hardware and software working in tandem, really determines how useful the computer is to us. In other words, it's all about User Interface, and even though "In the Beginning, There Was the Command Line", it's also true that In The Beginning, Information Took Fewer Forms.

The Macintosh OS was a revolution in both the good and bad senses of that word. Obviously it was true that command line interfaces were not for everyone, and that it would be a good thing to make computers more accessible to a less technical audience--if not for altruistic reasons, then because those sorts of people constituted an incomparably vaster market. It was clear the the Mac's engineers saw a whole new country stretching out before them; you could almost hear them muttering, "Wow! We don't have to be bound by files as linear streams of bytes anymore, vive la revolution, let's see how far we can take this!" No command line interface was available on the Macintosh; you talked to it with the mouse, or not at all. This was a statement of sorts, a credential of revolutionary purity. It seemed that the designers of the Mac intended to sweep Command Line Interfaces into the dustbin of history.

Though Apple and Microsoft still design their operating system as though the common user should never see a command line, they have both learned that providing access to one is important. More on that later.

My own personal love affair with the Macintosh began in the spring of 1984 in a computer store in Cedar Rapids, Iowa, when a friend of mine--coincidentally, the son of the MGB owner--showed me a Macintosh running MacPaint, the revolutionary drawing program. It ended in July of 1995 when I tried to save a big important file on my Macintosh Powerbook and instead instead of doing so, it annihilated the data so thoroughly that two different disk crash utility programs were unable to find any trace that it had ever existed. During the intervening ten years, I had a passion for the MacOS that seemed righteous and reasonable at the time but in retrospect strikes me as being exactly the same sort of goofy infatuation that my friend's dad had with his car.

The introduction of the Mac triggered a sort of holy war in the computer world. Were GUIs a brilliant design innovation that made computers more human-centered and therefore accessible to the masses, leading us toward an unprecedented revolution in human society, or an insulting bit of audiovisual gimcrackery dreamed up by flaky Bay Area hacker types that stripped computers of their power and flexibility and turned the noble and serious work of computing into a childish video game?

This debate actually seems more interesting to me today than it did in the mid-1980s. But people more or less stopped debating it when Microsoft endorsed the idea of GUIs by coming out with the first Windows. At this point, command-line partisans were relegated to the status of silly old grouches, and a new conflict was touched off, between users of MacOS and users of Windows.

There was plenty to argue about. The first Macintoshes looked different from other PCs even when they were turned off: they consisted of one box containing both CPU (the part of the computer that does arithmetic on bits) and monitor screen. This was billed, at the time, as a philosophical statement of sorts: Apple wanted to make the personal computer into an appliance, like a toaster. But it also reflected the purely technical demands of running a graphical user interface. In a GUI machine, the chips that draw things on the screen have to be integrated with the computer's central processing unit, or CPU, to a far greater extent than is the case with command-line interfaces, which until recently didn't even know that they weren't just talking to teletypes.

This distinction was of a technical and abstract nature, but it became clearer when the machine crashed (it is commonly the case with technologies that you can get the best insight about how they work by watching them fail). When everything went to hell and the CPU began spewing out random bits, the result, on a CLI machine, was lines and lines of perfectly formed but random characters on the screen--known to cognoscenti as "going Cyrillic." But to the MacOS, the screen was not a teletype, but a place to put graphics; the image on the screen was a bitmap, a literal rendering of the contents of a particular portion of the computer's memory. When the computer crashed and wrote gibberish into the bitmap, the result was something that looked vaguely like static on a broken television set--a "snow crash."

And even after the introduction of Windows, the underlying differences endured; when a Windows machine got into trouble, the old command-line interface would fall down over the GUI like an asbestos fire curtain sealing off the proscenium of a burning opera. When a Macintosh got into trouble it presented you with a cartoon of a bomb, which was funny the first time you saw it.

That bomb also became the subject of myriad parodies, too. Though it's general meaning was obvious, it was really the least informative error message possible, and came to symbolize the condescending nature of the GUI. Bomb icons showed up on computer screens in comics, cartoons, and feature films, often paired with a ridiculous upbeat "DOINK!" noise.

And these were by no means superficial differences. The reversion of Windows to a CLI when it was in distress proved to Mac partisans that Windows was nothing more than a cheap facade, like a garish afghan flung over a rotted-out sofa. They were disturbed and annoyed by the sense that lurking underneath Windows' ostensibly user-friendly interface was--literally--a subtext.

Those early mac people must be spinning in their cubicles now.

For their part, Windows fans might have made the sour observation that all computers, even Macintoshes, were built on that same subtext, and that the refusal of Mac owners to admit that fact to themselves seemed to signal a willingness, almost an eagerness, to be duped.

Anyway, a Macintosh had to switch individual bits in the memory chips on the video card, and it had to do it very fast, and in arbitrarily complicated patterns. Nowadays this is cheap and easy, but in the technological regime that prevailed in the early 1980s, the only realistic way to do it was to build the motherboard (which contained the CPU) and the video system (which contained the memory that was mapped onto the screen) as a tightly integrated whole--hence the single, hermetically sealed case that made the Macintosh so distinctive.

When Windows came out, it was conspicuous for its ugliness, and its current successors, Windows 95 and Windows NT, are not things that people would pay money to look at either. Microsoft's complete disregard for aesthetics gave all of us Mac-lovers plenty of opportunities to look down our noses at them. That Windows looked an awful lot like a direct ripoff of MacOS gave us a burning sense of moral outrage to go with it. Among people who really knew and appreciated computers (hackers, in Steven Levy's non-pejorative sense of that word) and in a few other niches such as professional musicians, graphic artists and schoolteachers, the Macintosh, for a while, was simply the computer. It was seen as not only a superb piece of engineering, but an embodiment of certain ideals about the use of technology to benefit mankind, while Windows was seen as a pathetically clumsy imitation and a sinister world domination plot rolled into one. So very early, a pattern had been established that endures to this day: people dislike Microsoft, which is okay; but they dislike it for reasons that are poorly considered, and in the end, self-defeating.

Tell that to the small-business IT guy who plugs the network cable into the back of his freshly installed Windows XP box, only to have it infected with a virus in less than 20 seconds. Or the publishing house that spent ten thousand dollars upgrading Word, only to discover that their documents now looked like garbage to every editor and author they worked with. "Poorly considered and self-defeating" could just as easily describe the actions of a Microsoft customer.

CLASS STRUGGLE ON THE DESKTOP

Now that the Third Rail has been firmly grasped, it is worth reviewing some basic facts here: like any other publicly traded, for-profit corporation, Microsoft has, in effect, borrowed a bunch of money from some people (its stockholders) in order to be in the bit business. As an officer of that corporation, Bill Gates has one responsibility only, which is to maximize return on investment. He has done this incredibly well. Any actions taken in the world by Microsoft-any software released by them, for example--are basically epiphenomena, which can't be interpreted or understood except insofar as they reflect Bill Gates's execution of his one and only responsibility.

It follows that if Microsoft sells goods that are aesthetically unappealing, or that don't work very well, it does not mean that they are (respectively) philistines or half-wits. It is because Microsoft's excellent management has figured out that they can make more money for their stockholders by releasing stuff with obvious, known imperfections than they can by making it beautiful or bug-free. This is annoying, but (in the end) not half so annoying as watching Apple inscrutably and relentlessly destroy itself.

VERY TRUE.

Hostility towards Microsoft is not difficult to find on the Net, and it blends two strains: resentful people who feel Microsoft is too powerful, and disdainful people who think it's tacky. This is all strongly reminiscent of the heyday of Communism and Socialism, when the bourgeoisie were hated from both ends: by the proles, because they had all the money, and by the intelligentsia, because of their tendency to spend it on lawn ornaments. Microsoft is the very embodiment of modern high-tech prosperity--it is, in a word, bourgeois--and so it attracts all of the same gripes.

The opening "splash screen" for Microsoft Word 6.0 summed it up pretty neatly: when you started up the program you were treated to a picture of an expensive enamel pen lying across a couple of sheets of fancy-looking handmade writing paper. It was obviously a bid to make the software look classy, and it might have worked for some, but it failed for me, because the pen was a ballpoint, and I'm a fountain pen man. If Apple had done it, they would've used a Mont Blanc fountain pen, or maybe a Chinese calligraphy brush. And I doubt that this was an accident. Recently I spent a while re-installing Windows NT on one of my home computers, and many times had to double-click on the "Control Panel" icon. For reasons that are difficult to fathom, this icon consists of a picture of a clawhammer and a chisel or screwdriver resting on top of a file folder.

One could easily cite this as an example of how a lack of competition resulted in a lack of innovation. There was no reason not to think up a more sensible icon for the Control Panel. Yet for a dozen years, it remained a hammer and a chisel, until Microsoft replaced it with ... what's this ... a pencil and a checkbox? As before, users are expected to understand what it means through indoctrination alone. It conveys no information to a newcomer, and while that lack of information may seem trivial at first, an entire operating system littered with equally arbitrary symbols and widgets can steer the novice to a psychotic episode.

These aesthetic gaffes give one an almost uncontrollable urge to make fun of Microsoft, but again, it is all beside the point--if Microsoft had done focus group testing of possible alternative graphics, they probably would have found that the average mid-level office worker associated fountain pens with effete upper management toffs and was more comfortable with ballpoints. Likewise, the regular guys, the balding dads of the world who probably bear the brunt of setting up and maintaining home computers, can probably relate better to a picture of a clawhammer--while perhaps harboring fantasies of taking a real one to their balky computers.

This is the only way I can explain certain peculiar facts about the current market for operating systems, such as that ninety percent of all customers continue to buy station wagons off the Microsoft lot while free tanks are there for the taking, right across the street.

We also have to consider a little thing called ... advertising. And perhaps, aggressively pursued contracts. Embrace-and-extend, FUD, and free seminars (Punch and Pie!).

A string of ones and zeroes was not a difficult thing for Bill Gates to distribute, one he'd thought of the idea. The hard part was selling it--reassuring customers that they were actually getting something in return for their money.

Anyone who has ever bought a piece of software in a store has had the curiously deflating experience of taking the bright shrink-wrapped box home, tearing it open, finding that it's 95 percent air, throwing away all the little cards, party favors, and bits of trash, and loading the disk into the computer. The end result (after you've lost the disk) is nothing except some images on a computer screen, and some capabilities that weren't there before. Sometimes you don't even have that--you have a string of error messages instead. But your money is definitely gone. Now we are almost accustomed to this, but twenty years ago it was a very dicey business proposition. Bill Gates made it work anyway. He didn't make it work by selling the best software or offering the cheapest price. Instead he somehow got people to believe that they were receiving something in exchange for their money.

The streets of every city in the world are filled with those hulking, rattling station wagons. Anyone who doesn't own one feels a little weird, and wonders, in spite of himself, whether it might not be time to cease resistance and buy one; anyone who does, feels confident that he has acquired some meaningful possession, even on those days when the vehicle is up on a lift in an auto repair shop.

That worldwide demographic of computer owners usually got Windows when it came preinstalled on their system. They think of the OS and the equipment as the same package, and that package has just as much physical presence to a middle-class consumer as any other home appliance. In the specific case of software purchased later, people were already well accustomed to the idea of paying money for ephemeral data on disposable media. Back then, the media were known as cassettes. (Of the VCR, Audio, and 8-Track kind.)

All of this is perfectly congruent with membership in the bourgeoisie, which is as much a mental, as a material state. And it explains why Microsoft is regularly attacked, on the Net, from both sides. People who are inclined to feel poor and oppressed construe everything Microsoft does as some sinister Orwellian plot. People who like to think of themselves as intelligent and informed technology users are driven crazy by the clunkiness of Windows.

Nothing is more annoying to sophisticated people to see someone who is rich enough to know better being tacky--unless it is to realize, a moment later, that they probably know they are tacky and they simply don't care and they are going to go on being tacky, and rich, and happy, forever. Microsoft therefore bears the same relationship to the Silicon Valley elite as the Beverly Hillbillies did to their fussy banker, Mr. Drysdale--who is irritated not so much by the fact that the Clampetts moved to his neighborhood as by the knowledge that, when Jethro is seventy years old, he's still going to be talking like a hillbilly and wearing bib overalls, and he's still going to be a lot richer than Mr. Drysdale.

Even the hardware that Windows ran on, when compared to the machines put out by Apple, looked like white-trash stuff, and still mostly does. The reason was that Apple was and is a hardware company, while Microsoft was and is a software company. Apple therefore had a monopoly on hardware that could run MacOS, whereas Windows-compatible hardware came out of a free market. The free market seems to have decided that people will not pay for cool-looking computers; PC hardware makers who hire designers to make their stuff look distinctive get their clocks cleaned by Taiwanese clone makers punching out boxes that look as if they belong on cinderblocks in front of someone's trailer. But Apple could make their hardware as pretty as they wanted to and simply pass the higher prices on to their besotted consumers, like me. Only last week (I am writing this sentence in early Jan. 1999) the technology sections of all the newspapers were filled with adulatory press coverage of how Apple had released the iMac in several happenin' new colors like Blueberry and Tangerine.

Yeeech, the iMac. Worst mouse ever. On the other hand, I've got one presently acting as a company-wide mailserver in the basement.

Stephenson's description of Apple is painful, because it's accurate. In the late 90's the company had little going for it except the fading halo of previous successes. The iMac was seen by some as a return to the early principles of tight integration that made the Macintosh a hit in the first place, but the happy-go-lucky ad campaign embarrassed die-hard users just as surely as it attracted new ones. In retrospect, it's tempting to assume that the iMac was released mostly as a stopgap product to gain time and money for addressing the real problem: OS 9.

But the big question remains the same as ever: "Why are the Apple users besotted? What has hypnotized them so thoroughly? Are Apple devices really so pleasurable to use?"

Apple has always insisted on having a hardware monopoly, except for a brief period in the mid-1990s when they allowed clone-makers to compete with them, before subsequently putting them out of business. Macintosh hardware was, consequently, expensive. You didn't open it up and fool around with it because doing so would void the warranty. In fact the first Mac was specifically designed to be difficult to open--you needed a kit of exotic tools, which you could buy through little ads that began to appear in the back pages of magazines a few months after the Mac came out on the market. These ads always had a certain disreputable air about them, like pitches for lock-picking tools in the backs of lurid detective magazines.

This monopolistic policy can be explained in at least three different ways.

THE CHARITABLE EXPLANATION is that the hardware monopoly policy reflected a drive on Apple's part to provide a seamless, unified blending of hardware, operating system, and software. There is something to this. It is hard enough to make an OS that works well on one specific piece of hardware, designed and tested by engineers who work down the hallway from you, in the same company. Making an OS to work on arbitrary pieces of hardware, cranked out by rabidly entrepeneurial clonemakers on the other side of the International Date Line, is very difficult, and accounts for much of the troubles people have using Windows.

THE FINANCIAL EXPLANATION is that Apple, unlike Microsoft, is and always has been a hardware company. It simply depends on revenue from selling hardware, and cannot exist without it.

THE NOT-SO-CHARITABLE EXPLANATION has to do with Apple's corporate culture, which is rooted in Bay Area Baby Boomdom.

Oh boy, here we go. We've discarded the obvious and sensible answer, to pursue politics. I already got enough of this with the last Presidential election cycle.

Now, since I'm going to talk for a moment about culture, full disclosure is probably in order, to protect myself against allegations of conflict of interest and ethical turpitude: (1) Geographically I am a Seattleite, of a Saturnine temperament, and inclined to take a sour view of the Dionysian Bay Area, just as they tend to be annoyed and appalled by us. (2) Chronologically I am a post-Baby Boomer. I feel that way, at least, because I never experienced the fun and exciting parts of the whole Boomer scene--just spent a lot of time dutifully chuckling at Boomers' maddeningly pointless anecdotes about just how stoned they got on various occasions, and politely fielding their assertions about how great their music was. But even from this remove it was possible to glean certain patterns, and one that recurred as regularly as an urban legend was the one about how someone would move into a commune populated by sandal-wearing, peace-sign flashing flower children, and eventually discover that, underneath this facade, the guys who ran it were actually control freaks; and that, as living in a commune, where much lip service was paid to ideals of peace, love and harmony, had deprived them of normal, socially approved outlets for their control-freakdom, it tended to come out in other, invariably more sinister, ways.

Applying this to the case of Apple Computer will be left as an exercise for the reader, and not a very difficult exercise.

It is a bit unsettling, at first, to think of Apple as a control freak, because it is completely at odds with their corporate image. Weren't these the guys who aired the famous Super Bowl ads showing suited, blindfolded executives marching like lemmings off a cliff? Isn't this the company that even now runs ads picturing the Dalai Lama (except in Hong Kong) and Einstein and other offbeat rebels?

You gotta love advertising. While this campaign is at least as tacky as the Microsoft ads featuring office workers flying around on wires, an observer should be reminded of one big difference: The products that Apple rolls out on the red carpet represent actual innovation.

I don't consider the Tablet PC to be in the same league, either. The Tablet PC is essentially a big fat Apple Newton for the modern age, allowing a whole new generation of modern programs to be functionally inaccessible to their hapless user.

It is indeed the same company, and the fact that they have been able to plant this image of themselves as creative and rebellious free-thinkers in the minds of so many intelligent and media-hardened skeptics really gives one pause. It is testimony to the insidious power of expensive slick ad campaigns and, perhaps, to a certain amount of wishful thinking in the minds of people who fall for them. It also raises the question of why Microsoft is so bad at PR, when the history of Apple demonstrates that, by writing large checks to good ad agencies, you can plant a corporate image in the minds of intelligent people that is completely at odds with reality.

Yes, slick ad campaigns are the enemy of truth. But Apple owners are not fervent because they've been pumped up by an advertising blitz, they're fervent because the product itself has actually enhanced their life and work. They're not dazzled before they buy it, especially in this age of "switchers", they become happy afterwards.

(The answer, for people who don't like Damoclean questions, is that since Microsoft has won the hearts and minds of the silent majority--the bourgeoisie--they don't give a damn about having a slick image, any more then Dick Nixon did. "I want to believe,"--the mantra that Fox Mulder has pinned to his office wall in The X-Files--applies in different ways to these two companies; Mac partisans want to believe in the image of Apple purveyed in those ads, and in the notion that Macs are somehow fundamentally different from other computers, while Windows people want to believe that they are getting something for their money, engaging in a respectable business transaction).

Not just any business transaction, but a cost-effective one. That immediately removed Apple from the list, since their hardware was so much more expensive up front, and (at the time) didn't interact well with other computing platforms.

In any event, as of 1987, both MacOS and Windows were out on the market, running on hardware platforms that were radically different from each other--not only in the sense that MacOS used Motorola CPU chips while Windows used Intel, but in the sense--then overlooked, but in the long run, vastly more significant--that the Apple hardware business was a rigid monopoly and the Windows side was a churning free-for-all.

But the full ramifications of this did not become clear until very recently--in fact, they are still unfolding, in remarkably strange ways, as I'll explain when we get to Linux. The upshot is that millions of people got accustomed to using GUIs in one form or another. By doing so, they made Apple/Microsoft a lot of money. The fortunes of many people have become bound up with the ability of these companies to continue selling products whose salability is very much open to question.

HONEY-POT, TAR-PIT, WHATEVER

When Gates and Allen invented the idea of selling software, they ran into criticism from both hackers and sober-sided businesspeople. Hackers understood that software was just information, and objected to the idea of selling it. These objections were partly moral. The hackers were coming out of the scientific and academic world where it is imperative to make the results of one's work freely available to the public. They were also partly practical; how can you sell something that can be easily copied? Businesspeople, who are polar opposites of hackers in so many ways, had objections of their own. Accustomed to selling toasters and insurance policies, they naturally had a difficult time understanding how a long collection of ones and zeroes could constitute a salable product.

Obviously Microsoft prevailed over these objections, and so did Apple. But the objections still exist. The most hackerish of all the hackers, the Ur-hacker as it were, was and is Richard Stallman, who became so annoyed with the evil practice of selling software that, in 1984 (the same year that the Macintosh went on sale) he went off and founded something called the Free Software Foundation, which commenced work on something called GNU. Gnu is an acronym for Gnu's Not Unix, but this is a joke in more ways than one, because GNU most certainly IS Unix,. Because of trademark concerns ("Unix" is trademarked by AT&T) they simply could not claim that it was Unix, and so, just to be extra safe, they claimed that it wasn't. Notwithstanding the incomparable talent and drive possessed by Mr. Stallman and other GNU adherents, their project to build a free Unix to compete against Microsoft and Apple's OSes was a little bit like trying to dig a subway system with a teaspoon. Until, that is, the advent of Linux, which I will get to later.

But the basic idea of re-creating an operating system from scratch was perfectly sound and completely doable. It has been done many times. It is inherent in the very nature of operating systems.

Operating systems are not strictly necessary. There is no reason why a sufficiently dedicated coder could not start from nothing with every project and write fresh code to handle such basic, low-level operations as controlling the read/write heads on the disk drives and lighting up pixels on the screen. The very first computers had to be programmed in this way. But since nearly every program needs to carry out those same basic operations, this approach would lead to vast duplication of effort.

Nothing is more disagreeable to the hacker than duplication of effort. The first and most important mental habit that people develop when they learn how to write computer programs is to generalize, generalize, generalize. To make their code as modular and flexible as possible, breaking large problems down into small subroutines that can be used over and over again in different contexts. Consequently, the development of operating systems, despite being technically unnecessary, was inevitable. Because at its heart, an operating system is nothing more than a library containing the most commonly used code, written once (and hopefully written well) and then made available to every coder who needs it.

So a proprietary, closed, secret operating system is a contradiction in terms. It goes against the whole point of having an operating system. And it is impossible to keep them secret anyway. The source code--the original lines of text written by the programmers--can be kept secret. But an OS as a whole is a collection of small subroutines that do very specific, very clearly defined jobs. Exactly what those subroutines do has to be made public, quite explicitly and exactly, or else the OS is completely useless to programmers; they can't make use of those subroutines if they don't have a complete and perfect understanding of what the subroutines do.

The only thing that isn't made public is exactly how the subroutines do what they do. But once you know what a subroutine does, it's generally quite easy (if you are a hacker) to write one of your own that does exactly the same thing. It might take a while, and it is tedious and unrewarding, but in most cases it's not really hard.

What's hard, in hacking as in fiction, is not writing; it's deciding what to write. And the vendors of commercial OSes have already decided, and published their decisions.

This has been generally understood for a long time. MS-DOS was duplicated, functionally, by a rival product, written from scratch, called ProDOS, that did all of the same things in pretty much the same way. In other words, another company was able to write code that did all of the same things as MS-DOS and sell it at a profit. If you are using the Linux OS, you can get a free program called WINE which is a windows emulator; that is, you can open up a window on your desktop that runs windows programs. It means that a completely functional Windows OS has been recreated inside of Unix, like a ship in a bottle. And Unix itself, which is vastly more sophisticated than MS-DOS, has been built up from scratch many times over. Versions of it are sold by Sun, Hewlett-Packard, AT&T, Silicon Graphics, IBM, and others.

People have, in other words, been re-writing basic OS code for so long that all of the technology that constituted an "operating system" in the traditional (pre-GUI) sense of that phrase is now so cheap and common that it's literally free. Not only could Gates and Allen not sell MS-DOS today, they could not even give it away, because much more powerful OSes are already being given away. Even the original Windows (which was the only windows until 1995) has become worthless, in that there is no point in owning something that can be emulated inside of Linux--which is, itself, free.

In this way the OS business is very different from, say, the car business. Even an old rundown car has some value. You can use it for making runs to the dump, or strip it for parts. It is the fate of manufactured goods to slowly and gently depreciate as they get old and have to compete against more modern products.

But it is the fate of operating systems to become free.

Microsoft is a great software applications company. Applications--such as Microsoft Word--are an area where innovation brings real, direct, tangible benefits to users. The innovations might be new technology straight from the research department, or they might be in the category of bells and whistles, but in any event they are frequently useful and they seem to make users happy. And Microsoft is in the process of becoming a great research company. But Microsoft is not such a great operating systems company. And this is not necessarily because their operating systems are all that bad from a purely technological standpoint. Microsoft's OSes do have their problems, sure, but they are vastly better than they used to be, and they are adequate for most people.

Why, then, do I say that Microsoft is not such a great operating systems company? Because the very nature of operating systems is such that it is senseless for them to be developed and owned by a specific company. It's a thankless job to begin with. Applications create possibilities for millions of credulous users, whereas OSes impose limitations on thousands of grumpy coders, and so OS-makers will forever be on the shit-list of anyone who counts for anything in the high-tech world. Applications get used by people whose big problem is understanding all of their features, whereas OSes get hacked by coders who are annoyed by their limitations. The OS business has been good to Microsoft only insofar as it has given them the money they needed to launch a really good applications software business and to hire a lot of smart researchers. Now it really ought to be jettisoned, like a spent booster stage from a rocket. The big question is whether Microsoft is capable of doing this. Or is it addicted to OS sales in the same way as Apple is to selling hardware?

Keep in mind that Apple's ability to monopolize its own hardware supply was once cited, by learned observers, as a great advantage over Microsoft. At the time, it seemed to place them in a much stronger position. In the end, it nearly killed them, and may kill them yet. The problem, for Apple, was that most of the world's computer users ended up owning cheaper hardware. But cheap hardware couldn't run MacOS, and so these people switched to Windows.

Replace "hardware" with "operating systems," and "Apple" with "Microsoft" and you can see the same thing about to happen all over again. Microsoft dominates the OS market, which makes them money and seems like a great idea for now. But cheaper and better OSes are available, and they are growingly popular in parts of the world that are not so saturated with computers as the US. Ten years from now, most of the world's computer users may end up owning these cheaper OSes. But these OSes do not, for the time being, run any Microsoft applications, and so these people will use something else.

This situation may yet come to pass, but from a different angle. Any shift in OS preference in the desktop computer market is already dwarfed by the seismic shifting of computing tasks onto other devices, like cellphones, PDAs, media players, in-dash consoles, game systems, video recorders, et cetera, ... all interconnected. The desktop computer remains the ideal centerpiece for a lot of this interaction, but is increasingly non-essential for it to occur.

Microsoft knows this, and has been trying to head it off at the pass for a decade or more. They developed the XBOX as a crowbar for the game-console market. They developed Windows CE as a lanyard into the PDA market. The Tablet PC seemed to pop in from nowhere. It's evident to the casual observer that Microsoft knows it's in a shrinking space, and is trying hard to shimmy out.

Their more successful moves have been to diversify directly, by purchasing other business models, not just other OS markets. MSNBC for example. Now they need to open a chain of hot-dog stands.

To put it more directly: every time someone decides to use a non-Microsoft OS, Microsoft's OS division, obviously, loses a customer. But, as things stand now, Microsoft's applications division loses a customer too. This is not such a big deal as long as almost everyone uses Microsoft OSes. But as soon as Windows' market share begins to slip, the math starts to look pretty dismal for the people in Redmond.

This argument could be countered by saying that Microsoft could simply re-compile its applications to run under other OSes. But this strategy goes against most normal corporate instincts. Again the case of Apple is instructive. When things started to go south for Apple, they should have ported their OS to cheap PC hardware. But they didn't. Instead, they tried to make the most of their brilliant hardware, adding new features and expanding the product line. But this only had the effect of making their OS more dependent on these special hardware features, which made it worse for them in the end.

This is based on a common misunderstanding that Apple and Microsoft are in the same business. As I state several times in these notes, Apple and Microsoft are not. Comparing them is like comparing a restaurant supply store to a restaurant, or a muffler shop to a limo service. Their markets only intersect, and a good move for one might be disaster for the other.

Why would Apple want to switch from making $100 off the sale of a computer, to $10 off the sale of an OS? Their market- and mind-share would have to instantly increase by ten times just to break even on that move. Linux is downloadable for free -- why would any company deliberately compete with that? Even Microsoft is bailing out into other markets, as fast as it can.

Likewise, when Microsoft's position in the OS world is threatened, their corporate instincts will tell them to pile more new features into their operating systems, and then re-jigger their software applications to exploit those special features. But this will only have the effect of making their applications dependent on an OS with declining market share, and make it worse for them in the end.

The operating system market is a death-trap, a tar-pit, a slough of despond. There are only two reasons to invest in Apple and Microsoft. (1) each of these companies is in what we would call a co-dependency relationship with their customers. The customers Want To Believe, and Apple and Microsoft know how to give them what they want. (2) each company works very hard to add new features to their OSes, which works to secure customer loyalty, at least for a little while.

Accordingly, most of the remainder of this essay will be about those two topics.

THE TECHNOSPHERE

Unix is the only OS remaining whose GUI (a vast suite of code called the X Windows System) is separate from the OS in the old sense of the phrase. This is to say that you can run Unix in pure command-line mode if you want to, with no windows, icons, mouses, etc. whatsoever, and it will still be Unix and capable of doing everything Unix is supposed to do. But the other OSes: MacOS, the Windows family, and BeOS, have their GUIs tangled up with the old-fashioned OS functions to the extent that they have to run in GUI mode, or else they are not really running. So it's no longer really possible to think of GUIs as being distinct from the OS; they're now an inextricable part of the OSes that they belong to--and they are by far the largest part, and by far the most expensive and difficult part to create.

There are only two ways to sell a product: price and features. When OSes are free, OS companies cannot compete on price, and so they compete on features. This means that they are always trying to outdo each other writing code that, until recently, was not considered to be part of an OS at all: stuff like GUIs. This explains a lot about how these companies behave.

It explains why Microsoft added a browser to their OS, for example. It is easy to get free browsers, just as to get free OSes. If browsers are free, and OSes are free, it would seem that there is no way to make money from browsers or OSes. But if you can integrate a browser into the OS and thereby imbue both of them with new features, you have a salable product.

Setting aside, for the moment, the fact that this makes government anti-trust lawyers really mad, this strategy makes sense. At least, it makes sense if you assume (as Microsoft's management appears to) that the OS has to be protected at all costs. The real question is whether every new technological trend that comes down the pike ought to be used as a crutch to maintain the OS's dominant position. Confronted with the Web phenomenon, Microsoft had to develop a really good web browser, and they did. But then they had a choice: they could have made that browser work on many different OSes, which would give Microsoft a strong position in the Internet world no matter what happened to their OS market share. Or they could make the browser one with the OS, gambling that this would make the OS look so modern and sexy that it would help to preserve their dominance in that market. The problem is that when Microsoft's OS position begins to erode (and since it is currently at something like ninety percent, it can't go anywhere but down) it will drag everything else down with it.

In your high school geology class you probably were taught that all life on earth exists in a paper-thin shell called the biosphere, which is trapped between thousands of miles of dead rock underfoot, and cold dead radioactive empty space above. Companies that sell OSes exist in a sort of technosphere. Underneath is technology that has already become free. Above is technology that has yet to be developed, or that is too crazy and speculative to be productized just yet. Like the Earth's biosphere, the technosphere is very thin compared to what is above and what is below.

But it moves a lot faster. In various parts of our world, it is possible to go and visit rich fossil beds where skeleton lies piled upon skeleton, recent ones on top and more ancient ones below. In theory they go all the way back to the first single-celled organisms. And if you use your imagination a bit, you can understand that, if you hang around long enough, you'll become fossilized there too, and in time some more advanced organism will become fossilized on top of you.

The fossil record--the La Brea Tar Pit--of software technology is the Internet. Anything that shows up there is free for the taking (possibly illegal, but free). Executives at companies like Microsoft must get used to the experience--unthinkable in other industries--of throwing millions of dollars into the development of new technologies, such as Web browsers, and then seeing the same or equivalent software show up on the Internet two years, or a year, or even just a few months, later.

By continuing to develop new technologies and add features onto their products they can keep one step ahead of the fossilization process, but on certain days they must feel like mammoths caught at La Brea, using all their energies to pull their feet, over and over again, out of the sucking hot tar that wants to cover and envelop them.

Survival in this biosphere demands sharp tusks and heavy, stomping feet at one end of the organization, and Microsoft famously has those. But trampling the other mammoths into the tar can only keep you alive for so long. The danger is that in their obsession with staying out of the fossil beds, these companies will forget about what lies above the biosphere: the realm of new technology. In other words, they must hang onto their primitive weapons and crude competitive instincts, but also evolve powerful brains. This appears to be what Microsoft is doing with its research division, which has been hiring smart people right and left (Here I should mention that although I know, and socialize with, several people in that company's research division, we never talk about business issues and I have little to no idea what the hell they are up to. I have learned much more about Microsoft by using the Linux operating system than I ever would have done by using Windows).

Never mind how Microsoft used to make money; today, it is making its money on a kind of temporal arbitrage. "Arbitrage," in the usual sense, means to make money by taking advantage of differences in the price of something between different markets. It is spatial, in other words, and hinges on the arbitrageur knowing what is going on simultaneously in different places. Microsoft is making money by taking advantage of differences in the price of technology in different times. Temporal arbitrage, if I may coin a phrase, hinges on the arbitrageur knowing what technologies people will pay money for next year, and how soon afterwards those same technologies will become free. What spatial and temporal arbitrage have in common is that both hinge on the arbitrageur's being extremely well-informed; one about price gradients across space at a given time, and the other about price gradients over time in a given place.

So Apple/Microsoft shower new features upon their users almost daily, in the hopes that a steady stream of genuine technical innovations, combined with the "I want to believe" phenomenon, will prevent their customers from looking across the road towards the cheaper and better OSes that are available to them. The question is whether this makes sense in the long run. If Microsoft is addicted to OSes as Apple is to hardware, then they will bet the whole farm on their OSes, and tie all of their new applications and technologies to them. Their continued survival will then depend on these two things: adding more features to their OSes so that customers will not switch to the cheaper alternatives, and maintaining the image that, in some mysterious way, gives those customers the feeling that they are getting something for their money.

The latter is a truly strange and interesting cultural phenomenon.

This is a well constructed description of what motivated Microsoft and Apple during the 90's, however it implies that the development of the GUI and the Operating System is now purely reliant on bells and whistles -- all that remains is a ghostly aura of legitimacy around a product that should otherwise be free. That idea only makes sense if it is applicable to all software -- from OmniPage to ProTools to Route 66. (Note that OmniPage compels the sale of scanners, ProTools compels the sale of breakout boxes, and Route 66 compels the sale of GPS dongles)

But software is never perfected, just as creatures never evolve to perfection. In both cases, we see instead an ongoing struggle to adapt to a shifting environment. In the case of software, that environment is the ever-changing (and ever-expanding) role of the computer in society.

The big evolutionary step of the last five years has been networking technology. The OS and the GUI still have plenty to do.

THE INTERFACE CULTURE

A few years ago I walked into a grocery store somewhere and was presented with the following tableau vivant: near the entrance a young couple were standing in front of a large cosmetics display. The man was stolidly holding a shopping basket between his hands while his mate raked blister-packs of makeup off the display and piled them in. Since then I've always thought of that man as the personification of an interesting human tendency: not only are we not offended to be dazzled by manufactured images, but we like it. We practically insist on it. We are eager to be complicit in our own dazzlement: to pay money for a theme park ride, vote for a guy who's obviously lying to us, or stand there holding the basket as it's filled up with cosmetics.

I was in Disney World recently, specifically the part of it called the Magic Kingdom, walking up Main Street USA. This is a perfect gingerbready Victorian small town that culminates in a Disney castle. It was very crowded; we shuffled rather than walked. Directly in front of me was a man with a camcorder. It was one of the new breed of camcorders where instead of peering through a viewfinder you gaze at a flat-panel color screen about the size of a playing card, which televises live coverage of whatever the camcorder is seeing. He was holding the appliance close to his face, so that it obstructed his view. Rather than go see a real small town for free, he had paid money to see a pretend one, and rather than see it with the naked eye he was watching it on television.

And rather than stay home and read a book, I was watching him.

Americans' preference for mediated experiences is obvious enough, and I'm not going to keep pounding it into the ground. I'm not even going to make snotty comments about it--after all, I was at Disney World as a paying customer. But it clearly relates to the colossal success of GUIs and so I have to talk about it some. Disney does mediated experiences better than anyone. If they understood what OSes are, and why people use them, they could crush Microsoft in a year or two.

In the part of Disney World called the Animal Kingdom there is a new attraction, slated to open in March 1999, called the Maharajah Jungle Trek. It was open for sneak previews when I was there. This is a complete stone-by-stone reproduction of a hypothetical ruin in the jungles of India. According to its backstory, it was built by a local rajah in the 16th Century as a game reserve. He would go there with his princely guests to hunt Bengal tigers. As time went on it fell into disrepair and the tigers and monkeys took it over; eventually, around the time of India's independence, it became a government wildlife reserve, now open to visitors.

The place looks more like what I have just described than any actual building you might find in India. All the stones in the broken walls are weathered as if monsoon rains had been trickling down them for centuries, the paint on the gorgeous murals is flaked and faded just so, and Bengal tigers loll amid stumps of broken columns. Where modern repairs have been made to the ancient structure, they've been done, not as Disney's engineers would do them, but as thrifty Indian janitors would--with hunks of bamboo and rust-spotted hunks of rebar. The rust is painted on, or course, and protected from real rust by a plastic clear-coat, but you can't tell unless you get down on your knees.

In one place you walk along a stone wall with a series of old pitted friezes carved into it. One end of the wall has broken off and settled into the earth, perhaps because of some long-forgotten earthquake, and so a broad jagged crack runs across a panel or two, but the story is still readable: first, primordial chaos leads to a flourishing of many animal species. Next, we see the Tree of Life surrounded by diverse animals. This is an obvious allusion (or, in showbiz lingo, a tie-in) to the gigantic Tree of Life that dominates the center of Disney's Animal Kingdom just as the Castle dominates the Magic Kingdom or the Sphere does Epcot. But it's rendered in historically correct style and could probably fool anyone who didn't have a Ph.D. in Indian art history.

The next panel shows a mustachioed H. sapiens chopping down the Tree of Life with a scimitar, and the animals fleeing every which way. The one after that shows the misguided human getting walloped by a tidal wave, part of a latter-day Deluge presumably brought on by his stupidity.

The final panel, then, portrays the Sapling of Life beginning to grow back, but now Man has ditched the edged weapon and joined the other animals in standing around to adore and praise it.

It is, in other words, a prophecy of the Bottleneck: the scenario, commonly espoused among modern-day environmentalists, that the world faces an upcoming period of grave ecological tribulations that will last for a few decades or centuries and end when we find a new harmonious modus vivendi with Nature.

Taken as a whole the frieze is a pretty brilliant piece of work. Obviously it's not an ancient Indian ruin, and some person or people now living deserve credit for it. But there are no signatures on the Maharajah's game reserve at Disney World. There are no signatures on anything, because it would ruin the whole effect to have long strings of production credits dangling from every custom-worn brick, as they do from Hollywood movies.

Among Hollywood writers, Disney has the reputation of being a real wicked stepmother. It's not hard to see why. Disney is in the business of putting out a product of seamless illusion--a magic mirror that reflects the world back better than it really is. But a writer is literally talking to his or her readers, not just creating an ambience or presenting them with something to look at; and just as the command-line interface opens a much more direct and explicit channel from user to machine than the GUI, so it is with words, writer, and reader.

The word, in the end, is the only system of encoding thoughts--the only medium--that is not fungible, that refuses to dissolve in the devouring torrent of electronic media (the richer tourists at Disney World wear t-shirts printed with the names of famous designers, because designs themselves can be bootlegged easily and with impunity. The only way to make clothing that cannot be legally bootlegged is to print copyrighted and trademarked words on it; once you have taken that step, the clothing itself doesn't really matter, and so a t-shirt is as good as anything else. T-shirts with expensive words on them are now the insignia of the upper class. T-shirts with cheap words, or no words at all, are for the commoners).

But this special quality of words and of written communication would have the same effect on Disney's product as spray-painted graffiti on a magic mirror. So Disney does most of its communication without resorting to words, and for the most part, the words aren't missed. Some of Disney's older properties, such as Peter Pan, Winnie the Pooh, and Alice in Wonderland, came out of books. But the authors' names are rarely if ever mentioned, and you can't buy the original books at the Disney store. If you could, they would all seem old and queer, like very bad knockoffs of the purer, more authentic Disney versions. Compared to more recent productions like Beauty and the Beast and Mulan, the Disney movies based on these books (particularly Alice in Wonderland and Peter Pan) seem deeply bizarre, and not wholly appropriate for children. That stands to reason, because Lewis Carroll and J.M. Barrie were very strange men, and such is the nature of the written word that their personal strangeness shines straight through all the layers of Disneyfication like x-rays through a wall. Probably for this very reason, Disney seems to have stopped buying books altogether, and now finds its themes and characters in folk tales, which have the lapidary, time-worn quality of the ancient bricks in the Maharajah's ruins.

If I can risk a broad generalization, most of the people who go to Disney World have zero interest in absorbing new ideas from books. Which sounds snide, but listen: they have no qualms about being presented with ideas in other forms. Disney World is stuffed with environmental messages now, and the guides at Animal Kingdom can talk your ear off about biology.

If you followed those tourists home, you might find art, but it would be the sort of unsigned folk art that's for sale in Disney World's African- and Asian-themed stores. In general they only seem comfortable with media that have been ratified by great age, massive popular acceptance, or both.

In this world, artists are like the anonymous, illiterate stone carvers who built the great cathedrals of Europe and then faded away into unmarked graves in the churchyard. The cathedral as a whole is awesome and stirring in spite, and possibly because, of the fact that we have no idea who built it. When we walk through it we are communing not with individual stone carvers but with an entire culture.

Disney World works the same way. If you are an intellectual type, a reader or writer of books, the nicest thing you can say about this is that the execution is superb. But it's easy to find the whole environment a little creepy, because something is missing: the translation of all its content into clear explicit written words, the attribution of the ideas to specific people. You can't argue with it. It seems as if a hell of a lot might be being glossed over, as if Disney World might be putting one over on us, and possibly getting away with all kinds of buried assumptions and muddled thinking.

But this is precisely the same as what is lost in the transition from the command-line interface to the GUI.

Disney and Apple/Microsoft are in the same business: short-circuiting laborious, explicit verbal communication with expensively designed interfaces. Disney is a sort of user interface unto itself--and more than just graphical. Let's call it a Sensorial Interface. It can be applied to anything in the world, real or imagined, albeit at staggering expense.

Why are we rejecting explicit word-based interfaces, and embracing graphical or sensorial ones--a trend that accounts for the success of both Microsoft and Disney?

Part of it is simply that the world is very complicated now--much more complicated than the hunter-gatherer world that our brains evolved to cope with--and we simply can't handle all of the details. We have to delegate. We have no choice but to trust some nameless artist at Disney or programmer at Apple or Microsoft to make a few choices for us, close off some options, and give us a conveniently packaged executive summary.

But more importantly, it comes out of the fact that, during this century, intellectualism failed, and everyone knows it. In places like Russia and Germany, the common people agreed to loosen their grip on traditional folkways, mores, and religion, and let the intellectuals run with the ball, and they screwed everything up and turned the century into an abbatoir. Those wordy intellectuals used to be merely tedious; now they seem kind of dangerous as well.

We Americans are the only ones who didn't get creamed at some point during all of this. We are free and prosperous because we have inherited political and values systems fabricated by a particular set of eighteenth-century intellectuals who happened to get it right. But we have lost touch with those intellectuals, and with anything like intellectualism, even to the point of not reading books any more, though we are literate. We seem much more comfortable with propagating those values to future generations nonverbally, through a process of being steeped in media. Apparently this actually works to some degree, for police in many lands are now complaining that local arrestees are insisting on having their Miranda rights read to them, just like perps in American TV cop shows. When it's explained to them that they are in a different country, where those rights do not exist, they become outraged. Starsky and Hutch reruns, dubbed into diverse languages, may turn out, in the long run, to be a greater force for human rights than the Declaration of Independence.

A huge, rich, nuclear-tipped culture that propagates its core values through media steepage seems like a bad idea. There is an obvious risk of running astray here.

Now that this extensive digression is in full swing, let me see if I can separate the politics from the argument.

Stephenson is talking about the difference between specific, serial, written communication -- like the exacting language of a legal document -- and visual, approximate, symbolic communication. The difference between a book and a television for example, or between the command line and the icon-driven windowed user interface. He mixes this comparison with a diatribe on the pervasiveness of U.S. culture, comparing the dissemination of Starsky and Hutch reruns, made in Hollywood, with the dissemination of the U.S. Bill of Rights. He asserts that Starsky and Hutch reruns may be a greater force for freedom than the Declaration of Independence, because most modern people are exposed to the ideas of freedom via television shows.

That assertion is reasonable, but only if we consider the forefront of modern media, and not the history. Why do we have a show called Starsky and Hutch, instead of, say, Junta and Warlord? Is it just a random coincidence that our television shows reflect the same ideas that our most venerated government documents laid out, two hundred years ago?

Of course not, and that's an important fact. New media is based on old media, whether topping a progression, or filling a hole. In the modern world we can deliver media everywhere and at great speed, but that infrastructure makes no promises about the ideological content of the media. Those choices are made by other means. And so, we are broadcasting a show about heroic cops, intent on doing good by our laws, and a police system that is a respectable and necessary branch of government, because it's what we expect and aspire to. Those aspirations can be traced easily back to the Constitution, the Bill of Rights, and other related political documents and common-law trends. In other words, approximate, symbolic media is interpreted on a foundation of specific, exact media, like bedrock under a forest. We retain that bedrock because the specific, exact media is the only kind that survives the ravages of time.

If we acknowledge this history, we understand that the risk of "running astray" is largely kept in check by the conceptual weight of all the information that's already available. The risk may be even further mitigated by the concepts that the network itself embodies - the decentralized, reliable, independent exchange of information that all our modern technologies are moving towards.

If all the hard drives, CD-ROMS, sculptures, paperbacks, film cans, and paintings were to vanish instantaneously one day, leaving the network intact but utterly blank, how far back would human progress be set? Which direction would society go, after the intial chaos and confusion?

Words are the only immutable medium we have, which is why they are the vehicle of choice for extremely important concepts like the Ten Commandments, the Koran, and the Bill of Rights. Unless the messages conveyed by our media are somehow pegged to a fixed, written set of precepts, they can wander all over the place and possibly dump loads of crap into people's minds.

And even the written word is not an immutable medium. Look at how many crazy ideas have been inferred from various mis-translated Bible passages. (Sodomy and shellfish are equal abominations, for example.) Common words like "troll", "geek", "call", "wired", and "gay" have changed incredibly. These changes are accelerating, too. Now we even use bizarre acronyms in everyday communication, like "LOL", "OMG", "WTF" ... and the endlessly irritating "dot-com".

However, as immutable mediums go, the written word is the best we have. And perhaps it should be alarming that people prefer to exchange information through other means, since it predicts a scary future in which most people cannot read or write but instead press buttons with pictures on them to get goods and services. But how scary is this, really? It's true that most of our ancestors were illiterate, and lived short, agonizing lives. But they weren't miserable because they couldn't read or write, they were miserable because they didn't have buttons that spit out goods and services.

In any case, I find this scenario of future illiteracy to be unlikely. Industrialized society has infinitely expanded the opportunities for people to use words, at the same time it has reduced their formality. Middle-class citizens send instant messages, read web pages, and write email, in volumes far greater than their ancestors hand-wrote letters, or read the newspaper. We are experiencing nothing less than a revolution in writing. If words are in any danger, it is, as Stephenson implies earlier, from overuse!

Orlando used to have a military installation called McCoy Air Force Base, with long runways from which B-52s could take off and reach Cuba, or just about anywhere else, with loads of nukes. But now McCoy has been scrapped and repurposed. It has been absorbed into Orlando's civilian airport. The long runways are being used to land 747-loads of tourists from Brazil, Italy, Russia and Japan, so that they can come to Disney World and steep in our media for a while.

To traditional cultures, especially word-based ones such as Islam, this is infinitely more threatening than the B-52s ever were. It is obvious, to everyone outside of the United States, that our arch-buzzwords, multiculturalism and diversity, are false fronts that are being used (in many cases unwittingly) to conceal a global trend to eradicate cultural differences. The basic tenet of multiculturalism (or "honoring diversity" or whatever you want to call it) is that people need to stop judging each other-to stop asserting (and, eventually, to stop believing) that this is right and that is wrong, this true and that false, one thing ugly and another thing beautiful, that God exists and has this or that set of qualities.

Okay, I've got to digress here and talk directly to the essay.

The United States is considered a "Great Melting Pot". This vivid nickname is not used in a derisive way, either. A lot of people are proud of the fact that many diverse cultures have not only transplanted to America, but have in fact dissolved into each other at the edges, or dissolved entirely.

This is not multiculturalism! Before I go any further, let me define multiculturalism: The idea that several different cultures (rather than one national culture) can co-exist peacefully and equitably in a single country.

This is also not cultural relativism! Let me define that too: The concept that the importance of a particular cultural idea varies from one society to another, and the view that ethical and moral standards are relative to what a particular society or culture believes to be good or bad, right or wrong.

The great -- and largely accidental -- innovation of America's "Great Melting Pot", is a mixing of people who are, step by step, deciding what they do and don't approve of in each other's practices, and arriving at an agreed median. The tolerance of multiculturalism, and the open, relativistic mind, is only the starting line for this process of integration. (And even that starting point is wickedly hard to reach.)

So when you say that the basic tenet of cultural relativism is to stop asserting one's beliefs, you're stating things very extremely. But it doesn't matter, because the general practice in America is not relativism, or multiculturism. It is integration. Melting together. Multiculturalism is what happens in a pot with no fire under it. Everyone stays in their assigned seating, and decides to "tolerate" everyone beyond the insular crowd they were raised with.

So what about cultural imperialism? In my opinion, that is the more derisive name that people have for this same process, when it happens outside of U.S. borders. But it is, in large part, the same process. (It is disturbing that some people would compare this to, say, the campaign to eradicate the Jews from Germany.) To those of you who witness the American culture "subsuming" the culture of an indigenous people: What would you rather have instead? Cultural relativism? Take your argument to the people themselves. They're the ones clamoring for their color TVs, hip-hop, and internet. Not fair, you say, because American culture is addictive and poisonous, like a McDonalds hamburger? Those poor indigenous cultures have no chance?

Here's another angle for you: Like a body immunized by the ceaseless battle against a hundred crippling diseases, perhaps the continuous simmering of the diverse American culture, through centuries of argument, has made it grow strong and healthy. I'm not saying that's the answer, but it's an equally viable interpretation.

If we can make such dissimilar conclusions from the same argument, then the argument must have a weak basis. The problem is that when people decry the spread of American culture, they're actually talking about something else. Americans don't personally travel to other countries, carrying portable television sets under each arm, and barge into people's homes declaring that they'll love American TV. They don't jam six-packs of Coca-Cola into their purses, and pass them out at tour-bus stops to make friends. They don't stuff their suitcases full of Big-Macs, fly to Tibet, and hurl hamburgers at passers-by in order to spread the joy.

American corporations do this. To expand business, they seek new markets overseas. And there's nothing inherently bad about global commerce. An established maker of toothbrushes can set up on foreign shores, and equip a million new customers for better oral hygiene, and the only people who lose out are the dentists. But on the other hand, an established maker of soft-drinks can set up on foreign shores, and wreck an entire generations' teeth, set the stage for a diabetes epidemic, and trigger a health-care crisis. The difference is not the behavior, but the product.

The big question that Americans must now consider is, in this dawning information age where we can speak as well as listen, broadcast as well as recieve, ... why are we letting the hucksters of crap speak on our behalf?

The lesson most people are taking home from the Twentieth Century is that, in order for a large number of different cultures to coexist peacefully on the globe (or even in a neighborhood) it is necessary for people to suspend judgment in this way. Hence (I would argue) our suspicion of, and hostility towards, all authority figures in modern culture. As David Foster Wallace has explained in his essay "E Unibus Pluram," this is the fundamental message of television; it is the message that people take home, anyway, after they have steeped in our media long enough. It's not expressed in these highfalutin terms, of course. It comes through as the presumption that all authority figures--teachers, generals, cops, ministers, politicians--are hypocritical buffoons, and that hip jaded coolness is the only way to be.

Television is mostly slime and drool, but it does exhibit more variety than this. Heck, they've been re-running episodes of "Law and Order" since the early 90's, and "all authority figures are hypocritical buffoons" is hardly the message that show conveys. Government conspiracies are sooo 1984.

(As an aside, Mr. Stephenson's opinion has evolved as well, and he pointed out in an interview that our modern information systems have been troubled more by mid-level abuse from vengeful employees, than top-level abuse by some government agency.)

Cultural differences are stomped on by mass media, yes. But to understand this is not to acquire "hip jaded coolness". It is an important lesson, one that will only grow more important with the expansion of our interconnected media system to more places, devices, and creators of content. People's distrust of mass-media will have to be converted into distrust of internet search engines. And while the tools will have to change, the healthy skepticism should remain healthy.

The problem is that once you have done away with the ability to make judgments as to right and wrong, true and false, etc., there's no real culture left. All that remains is clog dancing and macrame. The ability to make judgments, to believe things, is the entire it point of having a culture. I think this is why guys with machine guns sometimes pop up in places like Luxor, and begin pumping bullets into Westerners. They perfectly understand the lesson of McCoy Air Force Base. When their sons come home wearing Chicago Bulls caps with the bills turned sideways, the dads go out of their minds.

Perhaps they do. And fight it they may. But they will lose, and I have no pity for them. This is a scenario that has played itself out many times before, within U.S. borders.

* Once upon a time, our loopy government declared war on communism, when people were afraid the "Yellow Peril" would infiltrate their ranks, and make their kids into zombies, and stomp their entire society to bits.

* And once upon a time, Christian coalitions savagely fought rock music, as if sexual innuendo and electric guitar were powerful enough to make their kids into zombies, and stomp their entire society to bits. Then the same thing happened again with rap music. Then it happened again with Goth music. And again with the hapless ravers.

* What's more, our government is still fighting a "war on drugs", because, as everybody from the 60s knows, just a few hits from the bong will turn you into a mindless zombie, and you'll go off and stomp society to bits, and join a commune.

* And right now, religious organizations are at war with homosexuality, because the 'gay lifestyle' will make their kids into zombies, and homosexuals will corrupt marriage and therefore the family unit and stomp their entire society to bits.

Society never did get stomped to bits. It just ate the new trend, shat out a few extremists, and kept rolling along. And what's the common thread in all of these scenarios? They were all wild-goose-chases, triggered by malformed prejudices at home. They were all revved into life by cynical people, who could not bear to trust in their fellow humans' ability to see common fucking sense, and wanted the law to mandate it for them.

And if this same cycle is now revving up around the world, in response to American culture, then so what? People need to learn that, for example, society will not implode if women wear bikinis. Even really small ones. That legally prohibiting all alcohol and recreational drug use is a losing battle. That racism is a waste of time, and separate is not equal. That any kind of music is, still, just music. And that if your son comes home wearing a Chicago Bulls cap with the bill turned sideways, it's really not a big deal. (And if he wants a pair of sneakers with stupid little lights in them, you can just tell him, "get a job".)

BUT. (And this is a big but.) The above examples are ideas promoted by the American people. Unfortunately, these are a small, undexposed subset of the ideas promoted by American advertisers. It's a common mistake to confuse the two, or tacitly assume that America is no more than the sum of its product placements. Such ideas include: People hate your zits. Soft drinks are sporty. Milk is essential. Your breath stinks. Your home is not secure. Shopping is joyful. You need four-wheel-drive. Bulimic girls are cute. Eating fast-food is fun, and smart. White teeth are important. Your kids are not safe. Nasty, watery beer is delicious, and a rite of passage, plus it gets you sex.

To various degrees, the American people are infected with all of these ideas. But how seriously we take them, on a person-to-person basis, is not as clear cut as television actors are paid to portray. Our strong national ideas about freedom of speech have been leveraged to establish one of the most permissive advertising climates in the world, and while I find it encouraging that society has stood up this well to such a sickening bombardment of crap, it's a resistance that shouldn't have to be maintained. We need to rebuild the way advertising standards are developed, and applied. Industry self-regulation has pretty much proven to be no regulation at all.

In the meantime, do not make the mistake of believing that the society portrayed by advertisers is the society in which you live. Do not make the mistake of believing that the people you see on TV are accurate representations of those you meet outside on the street. They are not accurate, by design. With ongoing scrutiny, you may discover that you know far less about the "real" world than your media feed has led you to believe.

The global anti-culture that has been conveyed into every cranny of the world by television is a culture unto itself, and by the standards of great and ancient cultures like Islam and France, it seems grossly inferior, at least at first. The only good thing you can say about it is that it makes world wars and Holocausts less likely--and that is actually a pretty good thing!

Now you're talkin'.

The only real problem is that anyone who has no culture, other than this global monoculture, is completely screwed. Anyone who grows up watching TV, never sees any religion or philosophy, is raised in an atmosphere of moral relativism, learns about civics from watching bimbo eruptions on network TV news, and attends a university where postmodernists vie to outdo each other in demolishing traditional notions of truth and quality, is going to come out into the world as one pretty feckless human being. And--again--perhaps the goal of all this is to make us feckless so we won't nuke each other.

So how did we end up with writers like Neal Stephenson? Shouldn't the great yawping vacuum of moral corruption have swallowed him whole by now, and made him into yet another simpering non-cultural dolt? Or does he sport a unique resistance to TV culture? Or ... perhaps TV culture is not the demon we suspect?

If I assume that cultural relativism rules the day, then it's a logical step for me to assume that American media is filling the air with white noise, static -- with a great big loud empty nothing. But I submit myself and you and everyone around us with half a brain and access to a keyboard as evidence that contradicts those assumptions.

I think of this media barrage not as a great empty space, but as a fertile, chaotic terrain of rivers and streams. With guidance from our friends and family, we learn to navigate it. That's what the growth process is all about now. We decide which streams -- which media feeds -- are important. Deciding which feeds enslave us, and which feeds enrich us.

People are not stupid. They realize the danger of using one source for all their vital information, and they don't like being manipulated, or even being in a position where it's possible. In addition, there's no reason they should have to fend for themselves, in an unregulated free-for-all of corporate misinformation cowering under the doctrine of "free speech". In my opinion, advertisers promoting a product should be held to the same standards that witnesses in a courtroom are, or found guilty of perjury and thrown off the air.

These are not impossible standards, either. Take a look at the UK's Advertising Standards Authority, for instance, specifically the section on how they remain independently funded.

On the other hand, if you are raised within some specific culture, you end up with a basic set of tools that you can use to think about and understand the world. You might use those tools to reject the culture you were raised in, but at least you've got some tools.

How can a person not be raised in a specific culture?

In this country, the people who run things--who populate major law firms and corporate boards--understand all of this at some level. They pay lip service to multiculturalism and diversity and non-judgmentalness, but they don't raise their own children that way. I have highly educated, technically sophisticated friends who have moved to small towns in Iowa to live and raise their children, and there are Hasidic Jewish enclaves in New York where large numbers of kids are being brought up according to traditional beliefs. Any suburban community might be thought of as a place where people who hold certain (mostly implicit) beliefs go to live among others who think the same way.

Welcome to the melting pot. In the scenario described above, the interconnectedness of our technology and media doesn't promote multiculturalism - it prevents it, by forcing us out of the complete isolation that an enclave always aspires to. It forces us to do more than "tolerate" those "out there", but actually deal with them in the living room and in the mind. We can't keep the differences stark and contentious, polishing them up and "celebrating" them, when we're lashed together with increasing force. Our kids will play on the same block.

And not only do these people feel some responsibility to their own children, but to the country as a whole. Some of the upper class are vile and cynical, of course, but many spend at least part of their time fretting about what direction the country is going in, and what responsibilities they have. And so issues that are important to book-reading intellectuals, such as global environmental collapse, eventually percolate through the porous buffer of mass culture and show up as ancient Hindu ruins in Orlando.

As they say on "G.I. Joe", "Knowing is half the battle." When I have kids, I'm not subscribing to cable TV. Nor will I allow soft drinks, drugs, or fast food, anywhere on the premises. I don't consume them and wouldn't want my kids to, either. Outside the house, my personal rules will have no real influence - but my voice in the community will.

And another thing, all you modern shut-ins: If you want your neighborhood to change, don't get on the internet and complain about it. Go talk to your neighbors. I bet you don't even know their names.

You may be asking: what the hell does all this have to do with operating systems? As I've explained, there is no way to explain the domination of the OS market by Apple/Microsoft without looking to cultural explanations, and so I can't get anywhere, in this essay, without first letting you know where I'm coming from vis-a-vis contemporary culture.

Contemporary culture is a two-tiered system, like the Morlocks and the Eloi in H.G. Wells's The Time Machine, except that it's been turned upside down. In The Time Machine the Eloi were an effete upper class, supported by lots of subterranean Morlocks who kept the technological wheels turning. But in our world it's the other way round. The Morlocks are in the minority, and they are running the show, because they understand how everything works. The much more numerous Eloi learn everything they know from being steeped from birth in electronic media directed and controlled by book-reading Morlocks. So many ignorant people could be dangerous if they got pointed in the wrong direction, and so we've evolved a popular culture that is (a) almost unbelievably infectious and (b) neuters every person who gets infected by it, by rendering them unwilling to make judgments and incapable of taking stands.

This assumes that ignorant people prefer being ignorant. I was ignorant when I was young. I got over it.

Point (a) -- that our culture is infectious -- is a factor of capitalism refining its product, if you tacitly assume that culture equals products. Point (b) -- that our culture neuters every person infected -- doesn't hold up to scrutiny. We're not less capable of taking stands. As we communicate and exchange, we become more capable of deciding what really matters.

But perhaps this debate is too subjective. I just generally don't find the world population to be a bunch of wishy-washy sheep who live to keep their heads buried in slop. That such creatures are the optimal targets of modern advertising practices, does not mean that the human race enjoys or even tolerates being reduced to such creatures. Would you look at a village built near a stagnant pond, and say, "Those stupid people! All they are is mosquito food!"? Or would you have the good grace to assume that the villagers have their own agenda as well?

Morlocks, who have the energy and intelligence to comprehend details, go out and master complex subjects and produce Disney-like Sensorial Interfaces so that Eloi can get the gist without having to strain their minds or endure boredom. Those Morlocks will go to India and tediously explore a hundred ruins, then come home and built sanitary bug-free versions: highlight films, as it were. This costs a lot, because Morlocks insist on good coffee and first-class airline tickets, but that's no problem because Eloi like to be dazzled and will gladly pay for it all.

Now I realize that most of this probably sounds snide and bitter to the point of absurdity: your basic snotty intellectual throwing a tantrum about those unlettered philistines. As if I were a self-styled Moses, coming down from the mountain all alone, carrying the stone tablets bearing the Ten Commandments carved in immutable stone--the original command-line interface--and blowing his stack at the weak, unenlightened Hebrews worshipping images. Not only that, but it sounds like I'm pumping some sort of conspiracy theory.

Unfortunately, you do, and you are. Tell ya what: Next time, don't bother with the disclaimer, and just use the delete key.

But that is not where I'm going with this. The situation I describe, here, could be bad, but doesn't have to be bad and isn't necessarily bad now:

* It simply is the case that we are way too busy, nowadays, to comprehend everything in detail. And it's better to comprehend it dimly, through an interface, than not at all. Better for ten million Eloi to go on the Kilimanjaro Safari at Disney World than for a thousand cardiovascular surgeons and mutual fund managers to go on "real" ones in Kenya.

We have to choose?

* The boundary between these two classes is more porous than I've made it sound. I'm always running into regular dudes--construction workers, auto mechanics, taxi drivers, galoots in general--who were largely aliterate until something made it necessary for them to become readers and start actually thinking about things. Perhaps they had to come to grips with alcoholism, perhaps they got sent to jail, or came down with a disease, or suffered a crisis in religious faith, or simply got bored. Such people can get up to speed on particular subjects quite rapidly. Sometimes their lack of a broad education makes them over-apt to go off on intellectual wild goose chases, but, hey, at least a wild goose chase gives you some exercise.

Yes, that's the problem here. This observation of 'regular dudes' in action invalidates the alarming description of a populace neutered by its own culture. Or are these people, too, drowning in a sea of unwashed monkeys? The "normal" people?

Perhaps the only "normal" people are the people we don't personally know, because our pride demands that "normal" be something other than ourselves. And yet, our perception of "normal" drastically effects the way we conduct ourselves to strangers, and the way we decide policy. Thus:

* The spectre of a polity controlled by the fads and whims of voters who actually believe that there are significant differences between Bud Lite and Miller Lite, and who think that professional wrestling is for real, is naturally alarming to people who don't. But then countries controlled via the command-line interface, as it were, by double-domed intellectuals, be they religious or secular, are generally miserable places to live.

But our choice is not just between a dictatorship, or a brain-dead orgy of fads and whims. I don't know why, but it's always hard to find intellectuals who retain faith in the idea of a self-governing populace. They behave as if governing were a burden grudgingly borne by the smart, as a service to the ungrateful stupid, whom they would rather just put to death. They have forgotten that the success of a government may be dependent on that government's structure. That a governor's actions from the seat of power have as much to do with the shape of the seat, as they do the mental might of the person occupying it.

Perhaps too many of them spend their winters indoors.

* Sophisticated people deride Disneyesque entertainments as pat and saccharine, but, hey, if the result of that is to instill basically warm and sympathetic reflexes, at a preverbal level, into hundreds of millions of unlettered media-steepers, then how bad can it be? We killed a lobster in our kitchen last night and my daughter cried for an hour. The Japanese, who used to be just about the fiercest people on earth, have become infatuated with cuddly adorable cartoon characters.

* My own family--the people I know best--is divided about evenly between people who will probably read this essay and people who almost certainly won't, and I can't say for sure that one group is necessarily warmer, happier, or better-adjusted than the other.

A definite case of trying to have our cake and eat it too! We should all keep this dichotimy in mind.

MORLOCKS AND ELOI AT THE KEYBOARD

Back in the days of the command-line interface, users were all Morlocks who had to convert their thoughts into alphanumeric symbols and type them in, a grindingly tedious process that stripped away all ambiguity, laid bare all hidden assumptions, and cruelly punished laziness and imprecision.

In short, it was a bad interface.

Then the interface-makers went to work on their GUIs, and introduced a new semiotic layer between people and machines. People who use such systems have abdicated the responsibility, and surrendered the power, of sending bits directly to the chip that's doing the arithmetic, and handed that responsibility and power over to the OS. This is tempting because giving clear instructions, to anyone or anything, is difficult. We cannot do it without thinking, and depending on the complexity of the situation, we may have to think hard about abstract things, and consider any number of ramifications, in order to do a good job of it. For most of us, this is hard work. We want things to be easier. How badly we want it can be measured by the size of Bill Gates's fortune.

It's not a matter of giving clear instructions. It's a matter of the machine being refined to suit the needs of the operator.

Consider the realm of cars. We use power-assist steering because it's too difficult to crank the wheels ourselves. The vehicle has become more complex, but its usage has been simplified, making it easier for us to accomplish our tasks.

If the car wasn't so heavy, we wouldn't need power steering. But internal combustion engines are heavy, and internal combustion engines are the best thing we've got for making wheeled devices go.

Now apply this progression to computers, in a reverse of the metaphor Mr. Stephenson applied earlier. Teletypes were noisy and wasted paper. The computer was not invented as a device for wasting paper, but for computing. Luckily, the television was sitting around, so we joined the two. The needs of computer operators were still met.

But now we had a device that could display arbitrary pictures, not just linear streams of symbols. Developers were bound to experiment with it, just like some car drivers are bound to eat food in their cars, glue spoilers on them, and crash them into swimming pools. Once the developers realized that pictures could make certain tasks much easier, the path of innovation was obvious. We substituted streams of commands for icons. Once we had icons on a screen, people felt more comfortable poking them directly instead of describing what they wanted via keyboard, and so the next innovation was a pointing device. The touch-screen never quite made it, but the mouse was a cheap alternative.

As I pointed out earlier, all of these refinements could be described as "layers of abstraction", heaped on top of the original teletype. But the true measure of abstraction is between the controls we manipulate, and the results we desire. The complexity of the intervening machine is irrelevant to us. In the case of computers, just as with automobiles, the machine has become extremely complex ... but getting results is easier than ever.

And that is because the complexity of our instructions to a machine, and the amount of toil required to get those instructions right, is not determined by the complexity of the machine itself. Instead, it depends on the quality of the user interface, which in turn should depend only on the complexity of the task we want to accomplish with the machine (though in practice it's influenced just as much by the level of technology available.)

To put it another way, computers are not inherently hard to use. But the old crappy ones were, because technology and design had not yet evolved interfaces suited to the tasks that computers were being leveraged in.

The OS has (therefore) become a sort of intellectual labor-saving device that tries to translate humans' vaguely expressed intentions into bits. In effect we are asking our computers to shoulder responsibilities that have always been considered the province of human beings--we want them to understand our desires, to anticipate our needs, to foresee consequences, to make connections, to handle routine chores without being asked, to remind us of what we ought to be reminded of while filtering out noise.

At the upper (which is to say, closer to the user) levels, this is done through a set of conventions--menus, buttons, and so on. These work in the sense that analogies work: they help Eloi understand abstract or unfamiliar concepts by likening them to something known. But the loftier word "metaphor" is used.

The overarching concept of the MacOS was the "desktop metaphor" and it subsumed any number of lesser (and frequently conflicting, or at least mixed) metaphors. Under a GUI, a file (frequently called "document") is metaphrased as a window on the screen (which is called a "desktop"). The window is almost always too small to contain the document and so you "move around," or, more pretentiously, "navigate" in the document by "clicking and dragging" the "thumb" on the "scroll bar." When you "type" (using a keyboard) or "draw" (using a "mouse") into the "window" or use pull-down "menus" and "dialog boxes" to manipulate its contents, the results of your labors get stored (at least in theory) in a "file," and later you can pull the same information back up into another "window." When you don't want it anymore, you "drag" it into the "trash."

Behold! Our language is morphing before our eyes. Nouns and verbs alike do the dance of modern adaptation! We live in an exciting time.

There is massively promiscuous metaphor-mixing going on here, and I could deconstruct it 'til the cows come home, but I won't. Consider only one word: "document." When we document something in the real world, we make fixed, permanent, immutable records of it. But computer documents are volatile, ephemeral constellations of data. Sometimes (as when you've just opened or saved them) the document as portrayed in the window is identical to what is stored, under the same name, in a file on the disk, but other times (as when you have made changes without saving them) it is completely different. In any case, every time you hit "Save" you annihilate the previous version of the "document" and replace it with whatever happens to be in the window at the moment. So even the word "save" is being used in a sense that is grotesquely misleading---"destroy one version, save another" would be more accurate.

Grotesque! The horrors of metaphor!

Anyone who uses a word processor for very long inevitably has the experience of putting hours of work into a long document and then losing it because the computer crashes or the power goes out. Until the moment that it disappears from the screen, the document seems every bit as solid and real as if it had been typed out in ink on paper. But in the next moment, without warning, it is completely and irretrievably gone, as if it had never existed. The user is left with a feeling of disorientation (to say nothing of annoyance) stemming from a kind of metaphor shear--you realize that you've been living and thinking inside of a metaphor that is essentially bogus.

Losing a document is a frustrating pain in the ass all by itself, and that feeling doesn't need to stem from anywhere else. The disorientation of which you speak, the bogus metaphor, is at most a transitional phenomenon experienced by people who grew up without computers, and accomplished their tasks on different machines in the past. Nowadays, any fool knows that an electric device that needs to remember things will sometimes forget those things if you yank out the battery.

I'll go into more detail on this later.

So GUIs use metaphors to make computing easier, but they are bad metaphors. Learning to use them is essentially a word game, a process of learning new definitions of words like "window" and "document" and "save" that are different from, and in many cases almost diametrically opposed to, the old. Somewhat improbably, this has worked very well, at least from a commercial standpoint, which is to say that Apple/Microsoft have made a lot of money off of it. All of the other modern operating systems have learned that in order to be accepted by users they must conceal their underlying gutwork beneath the same sort of spackle. This has some advantages: if you know how to use one GUI operating system, you can probably work out how to use any other in a few minutes. Everything works a little differently, like European plumbing--but with some fiddling around, you can type a memo or surf the web.

This simplistic characterization assumes that the elements of a graphical user interface are chosen arbitrarily, and that people are only able to use them through a kind of brute-force indoctrination. (Hellooo, Control Panel Icon!) Actually, a good user interface keeps the required indoctrination to an absolute minimum.

A good graphical user interface does this within the tacit assumption that every element presented is already an abstraction. That's what graphics are, after all - visual representations of other things. But knowing that we are looking at a picture, instead of the actual object, does not change the way we think of and relate to it. Understanding this, and deciding exactly what those objects on the screen should be and how they should behave, is a process that needs to be guided by something else entirely: The task we want to accomplish.

Most people who shop for OSes (if they bother to shop at all) are comparing not the underlying functions but the superficial look and feel. The average buyer of an OS is not really paying for, and is not especially interested in, the low-level code that allocates memory or writes bytes onto the disk. What we're really buying is a system of metaphors. And--much more important--what we're buying into is the underlying assumption that metaphors are a good way to deal with the world.

We all bought into that thousands of years ago, I'm afraid, when the first coins were minted.

Recently a lot of new hardware has become available that gives computers numerous interesting ways of affecting the real world: making paper spew out of printers, causing words to appear on screens thousands of miles away, shooting beams of radiation through cancer patients, creating realistic moving pictures of the Titanic. Windows is now used as an OS for cash registers and bank tellers' terminals. My satellite TV system uses a sort of GUI to change channels and show program guides. Modern cellular telephones have a crude GUI built into a tiny LCD screen. Even Legos now have a GUI: you can buy a Lego set called Mindstorms that enables you to build little Lego robots and program them through a GUI on your computer.

So we are now asking the GUI to do a lot more than serve as a glorified typewriter. Now we want to become a generalized tool for dealing with reality. This has become a bonanza for companies that make a living out of bringing new technology to the mass market.

Obviously you cannot sell a complicated technological system to people without some sort of interface that enables them to use it. The internal combustion engine was a technological marvel in its day, but useless as a consumer good until a clutch, transmission, steering wheel and throttle were connected to it. That odd collection of gizmos, which survives to this day in every car on the road, made up what we would today call a user interface. But if cars had been invented after Macintoshes, carmakers would not have bothered to gin up all of these arcane devices. We would have a computer screen instead of a dashboard, and a mouse (or at best a joystick) instead of a steering wheel, and we'd shift gears by pulling down a menu:

PARK

REVERSE

NEUTRAL

Help...

This is a bizarre notion. More development in technology provides more choices to designers, not fewer. Fads come and go, but a good interface has lasting power. To claim that a car designer would naturally favor a pull-down menu over, say, a steering wheel, is to belie a horrendous lack of faith in car designers.

A few lines of computer code can thus be made to substitute for any imaginable mechanical interface. The problem is that in many cases the substitute is a poor one. Driving a car through a GUI would be a miserable experience. Even if the GUI were perfectly bug-free, it would be incredibly dangerous, because menus and buttons simply can't be as responsive as direct mechanical controls. My friend's dad, the gentleman who was restoring the MGB, never would have bothered with it if it had been equipped with a GUI. It wouldn't have been any fun.

So - the GUI is an evil, inane creation, because it's replacing every other interface ever designed? That's a spectacular accusation to level at any interface, but it's especially poignant to accuse the GUI. The GUI is a collection of interactive drawings, used to empower people wishing to manipulate pure information, not some physical device like a toaster or a pogo stick.

The steering wheel and gearshift lever were invented during an era when the most complicated technology in most homes was a butter churn. Those early carmakers were simply lucky, in that they could dream up whatever interface was best suited to the task of driving an automobile, and people would learn it. Likewise with the dial telephone and the AM radio. By the time of the Second World War, most people knew several interfaces: they could not only churn butter but also drive a car, dial a telephone, turn on a radio, summon flame from a cigarette lighter, and change a light bulb.

Lucky? They were clearly hampered by the technology at hand. The rotary telephone was a stupid idea, and was only created as a workaround for easily sending the electric pulses that told switching equipment where to go. Once the clicks were replaced by brief musical chords, designers were free to use a loop of twelve buttons, and finally a grid, which made a lot more sense.

In the car, window cranks have been replaced by buttons. Same with door locks. Back in the day, the interfaces for these items had to be suited to the application of brute force by a human, but now they're machine-assisted, like power steering. You can now start the car by twisting a key in the drivers' seat, instead of standing out front and wildly spinning a handle. You can shift gears with a stick near the wheel, since you don't have to yank machinery into place with a lever any more. And the clutch and choke have disappeared entirely.

And don't even get me started on that punch-button AM-radio crap.

But now every little thing--wristwatches, VCRs, stoves--is jammed with features, and every feature is useless without an interface. If you are like me, and like most other consumers, you have never used ninety percent of the available features on your microwave oven, VCR, or cellphone. You don't even know that these features exist. The small benefit they might bring you is outweighed by the sheer hassle of having to learn about them. This has got to be a big problem for makers of consumer goods, because they can't compete without offering features.

It's only a problem for manufacturers who have stopped innovating in a particular field, and are instead applying patches and kludges. Progress means more than features. You can buy a $1200 electric mixer, all stainless steel with precision parts, a simple interface, plenty of power, and a lifetime warranty ... Or you can buy a $50 electric mixer, mostly plastic, and festooned with two dozen inscrutable buttons to lend it the appearance of sophistication. Feature clutter is only a problem for the bargain-basement arena that must compete on features, because they cannot compete on quality.

It's no longer acceptable for engineers to invent a wholly novel user interface for every new product, as they did in the case of the automobile, partly because it's too expensive and partly because ordinary people can only learn so much. If the VCR had been invented a hundred years ago, it would have come with a thumbwheel to adjust the tracking and a gearshift to change between forward and reverse and a big cast-iron handle to load or to eject the cassettes. It would have had a big analog clock on the front of it, and you would have set the time by moving the hands around on the dial. But because the VCR was invented when it was--during a sort of awkward transitional period between the era of mechanical interfaces and GUIs--it just had a bunch of pushbuttons on the front, and in order to set the time you had to push the buttons in just the right way. This must have seemed reasonable enough to the engineers responsible for it, but to many users it was simply impossible. Thus the famous blinking 12:00 that appears on so many VCRs. Computer people call this "the blinking twelve problem". When they talk about it, though, they usually aren't talking about VCRs.

Note: Stephenson said a few paragraphs ago that the automobile was NOT a wholly novel user interface, but was instead created to complement other tools that people were already familiar with. Now he appears to be contradicting that.

There is some wisdom contained in the fact that people will have an easier time using an interface that is built from elements they are already familiar with - buttons, wheels, levers, et cetera. However, this wisdom does not inform us about some alien quality of the GUI that mystifies the common man. Instead, this knowledge illuminates the connection that has always existed, in the physical world, between the task we wish a device to accomplish, and the way we most naturally manipulate that device.

This connection is somewhat anthropological in nature, based on every person's earliest understanding of what tools are: Objects that extend the influence of our bodies. Let's clarify that with a brief history:

After learning to pound things with their fists, young children discover that one of their toys that can be grasped and swung, having the same effect as their fist, but much greater force and no bothersome pain. (At least, for the wielder.) Playing in the yard, they may want to look under a rock, and they discover that the rock goes up easier if they wedge a stick under it, and pull up in the same way. What they are learning, is that if they want a tool to do some work, they will have to move their bodies in a way that emulates doing that work themselves, so their influence is communicated through the tool.

But modern man takes this simple lesson, and complicates it to the point of absurdity, so as soon as children learn about buttons, it's all over. Buttons can do anything. They can start a motor, cook a burrito, flush a toilet, or trigger a nuclear meltdown. From this, children get their first understanding of what an interface is, as something separate from the tool itself or the work they wish it to do. They realize that the components of an interface represent a kind of conceptual shorthand for the choices they must make.

Two examples:

A wheel on a device means that you can choose among a spectrum of results. If you need to make quick adjustments or big changes, it spins easily. If you need constant access to it, it's large and prominent. The wheel is a basic tool we are all comfortable grasping, and its presence on a more complicated device tells us something about the choices we can make.

When we push a lever, we want something to move from one place to another, and generally stay there. We extend this idea, by employing levers on a device when we want to choose between distinct and persistent states. A choice between two exclusive states, like on/off, naturally befits a lever or a switch.

So, people relate to an interface as an extension of themselves, and an extension of tools they already know about. And, people relate to an interface based on the choices they must make in using the device. Therefore, a well-designed user interface is one built on the intersection of these two relationships.

With this perspective, we don't need to blame the infamous "blinking twelve problem" on the newly invented phenomenon of the GUI. The truth was simple, really: An all-buttons interface for VCR programming just plain sucks. Buttons next to buttons, all the same size, each with a radically different purpose? Sucks. (Technically, late-80's VCRs didn't have graphics, and couldn't be said to have a GUI at all. That came later, in the mid-90's, with on-screen programming, and actually made things easier.)

Modern VCRs usually have some kind of on-screen programming, which means that you can set the time and control other features through a sort of primitive GUI. GUIs have virtual pushbuttons too, of course, but they also have other types of virtual controls, like radio buttons, checkboxes, text entry boxes, dials, and scrollbars. Interfaces made out of these components seem to be a lot easier, for many people, than pushing those little buttons on the front of the machine, and so the blinking 12:00 itself is slowly disappearing from America's living rooms. The blinking twelve problem has moved on to plague other technologies.

Ahh, good. Exactly the point I was looking for. Unfortunately, Stephenson sidestepped the framework that this point implies.

So the GUI has gone beyond being an interface to personal computers, and become a sort of meta-interface that is pressed into service for every new piece of consumer technology. It is rarely an ideal fit, but having an ideal, or even a good interface is no longer the priority; the important thing now is having some kind of interface that customers will actually use, so that manufacturers can claim, with a straight face, that they are offering new features.

We want GUIs largely because they are convenient and because they are easy-- or at least the GUI makes it seem that way Of course, nothing is really easy and simple, and putting a nice interface on top of it does not change that fact. A car controlled through a GUI would be easier to drive than one controlled through pedals and steering wheel, but it would be incredibly dangerous.

I'm ignoring the last sentence, which is just crazy. I would like to point out that all the controls mentioned above -- radio buttons, check boxes, scrollbars, et cetera -- while based upon physical controls, are not a replacement for those physical controls. When you're driving a car, your hands are on a set of physical controls, like a steering wheel and pedals. When you're operating a computer, your hands are on another set of controls. A mouse and a keyboard.

The metaphorical controls that are displayed in a Graphical User Interface, pictures of controls, are employed as a handy visual way of presenting the information, and the choices, associated with your task. No one assumes you are able to reach inside a video screen and twist a graphical knob like the physical one on your stove. It's all inside the computer -- behind a monitor, and behind a mouse, and people today are well aware of this. If they could jam down buttons on the screen with their finger, or poke at them with a stick, instead of with a mouse, that would be fine too. That's what the touch-screen and the PDA stylus do, respectively, and it's no coincidence that the GUI itself changes very little whether you are using one or the other.

But in both arenas -- user interface design in the physical world, and in the graphical one -- there are good choices and there are bad choices.

By using GUIs all the time we have insensibly bought into a premise that few people would have accepted if it were presented to them bluntly: namely, that hard things can be made easy, and complicated things simple, by putting the right interface on them. In order to understand how bizarre this is, imagine that book reviews were written according to the same values system that we apply to user interfaces: "The writing in this book is marvelously simple-minded and glib; the author glosses over complicated subjects and employs facile generalizations in almost every sentence. Readers rarely have to think, and are spared all of the difficulty and tedium typically involved in reading old-fashioned books." As long as we stick to simple operations like setting the clocks on our VCRs, this is not so bad. But as we try to do more ambitious things with our technologies, we inevitably run into the problem of:

Oops, lost the thread again.

METAPHOR SHEAR

That is, bad UI design.

I began using Microsoft Word as soon as the first version was released around 1985. After some initial hassles I found it to be a better tool than MacWrite, which was its only competition at the time. I wrote a lot of stuff in early versions of Word, storing it all on floppies, and transferred the contents of all my floppies to my first hard drive, which I acquired around 1987. As new versions of Word came out I faithfully upgraded, reasoning that as a writer it made sense for me to spend a certain amount of money on tools.

Sometime in the mid-1980's I attempted to open one of my old, circa-1985 Word documents using the version of Word then current: 6.0 It didn't work. Word 6.0 did not recognize a document created by an earlier version of itself. By opening it as a text file, I was able to recover the sequences of letters that made up the text of the document. My words were still there. But the formatting had been run through a log chipper--the words I'd written were interrupted by spates of empty rectangular boxes and gibberish.

Microsoft fucked you over? Join the club!

Now, in the context of a business (the chief market for Word) this sort of thing is only an annoyance--one of the routine hassles that go along with using computers. It's easy to buy little file converter programs that will take care of this problem. But if you are a writer whose career is words, whose professional identity is a corpus of written documents, this kind of thing is extremely disquieting. There are very few fixed assumptions in my line of work, but one of them is that once you have written a word, it is written, and cannot be unwritten. The ink stains the paper, the chisel cuts the stone, the stylus marks the clay, and something has irrevocably happened (my brother-in-law is a theologian who reads 3250-year-old cuneiform tablets--he can recognize the handwriting of particular scribes, and identify them by name). But word-processing software--particularly the sort that employs special, complex file formats--has the eldritch power to unwrite things. A small change in file formats, or a few twiddled bits, and months' or years' literary output can cease to exist.

Now this was technically a fault in the application (Word 6.0 for the Macintosh) not the operating system (MacOS 7 point something) and so the initial target of my annoyance was the people who were responsible for Word. But. On the other hand, I could have chosen the "save as text" option in Word and saved all of my documents as simple telegrams, and this problem would not have arisen. Instead I had allowed myself to be seduced by all of those flashy formatting options that hadn't even existed until GUIs had come along to make them practicable. I had gotten into the habit of using them to make my documents look pretty (perhaps prettier than they deserved to look; all of the old documents on those floppies turned out to be more or less crap). Now I was paying the price for that self-indulgence. Technology had moved on and found ways to make my documents look even prettier, and the consequence of it was that all old ugly documents had ceased to exist.

See above, re: Microsoft screwing us over. I've got membership cards printed and everything.

It was--if you'll pardon me for a moment's strange little fantasy--as if I'd gone to stay at some resort, some exquisitely designed and art-directed hotel, placing myself in the hands of past masters of the Sensorial Interface, and had sat down in my room and written a story in ballpoint pen on a yellow legal pad, and when I returned from dinner, discovered that the maid had taken my work away and left behind in its place a quill pen and a stack of fine parchment--explaining that the room looked ever so much finer this way, and it was all part of a routine upgrade. But written on these sheets of paper, in flawless penmanship, were long sequences of words chosen at random from the dictionary. Appalling, sure, but I couldn't really lodge a complaint with the management, because by staying at this resort I had given my consent to it. I had surrendered my Morlock credentials and become an Eloi.

LINUX

During the late 1980's and early 1990's I spent a lot of time programming Macintoshes, and eventually decided for fork over several hundred dollars for an Apple product called the Macintosh Programmer's Workshop, or MPW. MPW had competitors, but it was unquestionably the premier software development system for the Mac. It was what Apple's own engineers used to write Macintosh code. Given that MacOS was far more technologically advanced, at the time, than its competition, and that Linux did not even exist yet, and given that this was the actual program used by Apple's world-class team of creative engineers, I had high expectations. It arrived on a stack of floppy disks about a foot high, and so there was plenty of time for my excitement to build during the endless installation process. The first time I launched MPW, I was probably expecting some kind of touch-feely multimedia showcase. Instead it was austere, almost to the point of being intimidating. It was a scrolling window into which you could type simple, unformatted text. The system would then interpret these lines of text as commands, and try to execute them.

It was, in other words, a glass teletype running a command line interface. It came with all sorts of cryptic but powerful commands, which could be invoked by typing their names, and which I learned to use only gradually. It was not until a few years later, when I began messing around with Unix, that I understood that the command line interface embodied in MPW was a re-creation of Unix.

In other words, the first thing that Apple's hackers had done when they'd got the MacOS up and running--probably even before they'd gotten it up and running--was to re-create the Unix interface, so that they would be able to get some useful work done. At the time, I simply couldn't get my mind around this, but: as far as Apple's hackers were concerned, the Mac's vaunted Graphical User Interface was an impediment, something to be circumvented before the little toaster even came out onto the market.

It was not an impediment to getting work done - it was an impediment to getting programming done. Designing and implementing a GUI for a particular operation is hard. Especially doing it right. On the other hand, relying on the most basic UI built into all computers - even that early macintosh - of having various sequences of symbols on the keyboard precisely identify various commands to be executed, is very easy to program for.

All this hoopla over GUI elements has led some people to predict the death of the keyboard. Then came the Tablet PC from Microsoft -- and people have been complaining ever since, because most things that you would use a computer for, still involve letters and numbers. And those are easier to type than they are to write. Yes, even if you're a doctor rushing down a crowded hallway between patients. Now, give me decent voice recognition ...

However, even voice recognition is not the final word. (Plus, it's hard to wreck a nice beach.) Command-line interfaces and graphical user interfaces exist in a very messy spectrum. Now we have a mechanic in a greasy shop who needs to plug a car into a computer, and for him, a touchscreen is generally the best UI for the job. You don't have a mouse to grease up and break, you don't have a keyboard to spill cleaning fluid on or peck at with gloved fingers. And a touchscreen does not obviate a GUI either - you can just draw letters in a corner of the screen for the guy to poke at.

Even before my Powerbook crashed and obliterated my big file in July 1995, there had been danger signs. An old college buddy of mine, who starts and runs high-tech companies in Boston, had developed a commercial product using Macintoshes as the front end. Basically the Macs were high-performance graphics terminals, chosen for their sweet user interface, giving users access to a large database of graphical information stored on a network of much more powerful, but less user-friendly, computers. This fellow was the second person who turned me on to Macintoshes, by the way, and through the mid-1980's we had shared the thrill of being high-tech cognoscenti, using superior Apple technology in a world of DOS-using knuckleheads. Early versions of my friend's system had worked well, he told me, but when several machines joined the network, mysterious crashes began to occur; sometimes the whole network would just freeze. It was one of those bugs that could not be reproduced easily. Finally they figured out that these network crashes were triggered whenever a user, scanning the menus for a particular item, held down the mouse button for more than a couple of seconds.

Pbbbbtt. Stupid OS 7.

Fundamentally, the MacOS could only do one thing at a time. Drawing a menu on the screen is one thing. So when a menu was pulled down, the Macintosh was not capable of doing anything else until that indecisive user released the button.

This is not such a bad thing in a single-user, single-process machine (although it's a fairly bad thing), but it's no good in a machine that is on a network, because being on a network implies some kind of continual low-level interaction with other machines. By failing to respond to the network, the Mac caused a network-wide crash.

In order to work with other computers, and with networks, and with various different types of hardware, an OS must be incomparably more complicated and powerful than either MS-DOS or the original MacOS. The only way of connecting to the Internet that's worth taking seriously is PPP, the Point-to-Point Protocol, which (never mind the details) makes your computer--temporarily--a full-fledged member of the Global Internet, with its own unique address, and various privileges, powers, and responsibilities appertaining thereunto. Technically it means your machine is running the TCP/IP protocol, which, to make a long story short, revolves around sending packets of data back and forth, in no particular order, and at unpredictable times, according to a clever and elegant set of rules. But sending a packet of data is one thing, and so an OS that can only do one thing at a time cannot simultaneously be part of the Internet and do anything else. When TCP/IP was invented, running it was an honor reserved for Serious Computers--mainframes and high-powered minicomputers used in technical and commercial settings--and so the protocol is engineered around the assumption that every computer using it is a serious machine, capable of doing many things at once. Not to put too fine a point on it, a Unix machine. Neither MacOS nor MS-DOS was originally built with that in mind, and so when the Internet got hot, radical changes had to be made.

When my Powerbook broke my heart, and when Word stopped recognizing my old files, I jumped to Unix. The obvious alternative to MacOS would have been Windows. I didn't really have anything against Microsoft, or Windows. But it was pretty obvious, now, that old PC operating systems were overreaching, and showing the strain, and, perhaps, were best avoided until they had learned to walk and chew gum at the same time.

The changeover took place on a particular day in the summer of 1995. I had been San Francisco for a couple of weeks, using my PowerBook to work on a document. The document was too big to fit onto a single floppy, and so I hadn't made a backup since leaving home. The PowerBook crashed and wiped out the entire file.

It happened just as I was on my way out the door to visit a company called Electric Communities, which in those days was in Los Altos. I took my PowerBook with me. My friends at Electric Communities were Mac users who had all sorts of utility software for unerasing files and recovering from disk crashes, and I was certain I could get most of the file back.

As it turned out, two different Mac crash recovery utilities were unable to find any trace that my file had ever existed. It was completely and systematically wiped out. We went through that hard disk block by block and found disjointed fragments of countless old, discarded, forgotten files, but none of what I wanted. The metaphor shear was especially brutal that day. It was sort of like watching the girl you've been in love with for ten years get killed in a car wreck, and then attending her autopsy, and learning that underneath the clothes and makeup she was just flesh and blood.

I must have been reeling around the offices of Electric Communities in some kind of primal Jungian fugue, because at this moment three weirdly synchronistic things happened.

(1) Randy Farmer, a co-founder of the company, came in for a quick visit along with his family--he was recovering from back surgery at the time. He had some hot gossip: "Windows 95 mastered today." What this meant was that Microsoft's new operating system had, on this day, been placed on a special compact disk known as a golden master, which would be used to stamp out a jintillion copies in preparation for its thunderous release a few weeks later. This news was received peevishly by the staff of Electric Communities, including one whose office door was plastered with the usual assortment of cartoons and novelties, e.g.

(2) a copy of a Dilbert cartoon in which Dilbert, the long-suffering corporate software engineer, encounters a portly, bearded, hairy man of a certain age--a bit like Santa Claus, but darker, with a certain edge about him. Dilbert recognizes this man, based upon his appearance and affect, as a Unix hacker, and reacts with a certain mixture of nervousness, awe, and hostility. Dilbert jabs weakly at the disturbing interloper for a couple of frames; the Unix hacker listens with a kind of infuriating, beatific calm, then, in the last frame, reaches into his pocket. "Here's a nickel, kid," he says, "go buy yourself a real computer."

(3) the owner of the door, and the cartoon, was one Doug Barnes. Barnes was known to harbor certain heretical opinions on the subject of operating systems. Unlike most Bay Area techies who revered the Macintosh, considering it to be a true hacker's machine, Barnes was fond of pointing out that the Mac, with its hermetically sealed architecture, was actually hostile to hackers, who are prone to tinkering and dogmatic about openness. By contrast, the IBM-compatible line of machines, which can easily be taken apart and plugged back together, was much more hackable.

So when I got home I began messing around with Linux, which is one of many, many different concrete implementations of the abstract, Platonic ideal called Unix. I was not looking forward to changing over to a new OS, because my credit cards were still smoking from all the money I'd spent on Mac hardware over the years. But Linux's great virtue was, and is, that it would run on exactly the same sort of hardware as the Microsoft OSes--which is to say, the cheapest hardware in existence. As if to demonstrate why this was a great idea, I was, within a week or two of returning home, able to get my hand on a then-decent computer (a 33-MHz 486 box) for free, because I knew a guy who worked in an office where they were simply being thrown away. Once I got it home, I yanked the hood off, stuck my hands in, and began switching cards around. If something didn't work, I went to a used-computer outlet and pawed through a bin full of components and bought a new card for a few bucks.

The availability of all this cheap but effective hardware was an unintended consequence of decisions that had been made more than a decade earlier by IBM and Microsoft. When Windows came out, and brought the GUI to a much larger market, the hardware regime changed: the cost of color video cards and high-resolution monitors began to drop, and is dropping still. This free-for-all approach to hardware meant that Windows was unavoidably clunky compared to MacOS. But the GUI brought computing to such a vast audience that volume went way up and prices collapsed. Meanwhile Apple, which so badly wanted a clean, integrated OS with video neatly integrated into processing hardware, had fallen far behind in market share, at least partly because their beautiful hardware cost so much.

But the price that we Mac owners had to pay for superior aesthetics and engineering was not merely a financial one. There was a cultural price too, stemming from the fact that we couldn't open up the hood and mess around with it. Doug Barnes was right. Apple, in spite of its reputation as the machine of choice of scruffy, creative hacker types, had actually created a machine that discouraged hacking, while Microsoft, viewed as a technological laggard and copycat, had created a vast, disorderly parts bazaar--a primordial soup that eventually self-assembled into Linux.

OS X has turned this whole argument upside-down. OS X is more hackable than Windows, and does indeed have a command line interface built in. Not just tacked on, but built in, like the gooey center of an Oreo cookie.

And, tempting as it is to blame Microsoft for creating their own worst enemy, I would rather give that credit to the UNIX-fed Internet. No Internet, no Linux. No Open Source Software in general.

Why? Because the keystone of these creations is their appeal to previously anonymous contributors, and without the Internet, they could not be anonymous. They'd be part of a users' group, a lab, a company, a readership -- even if they were all just customers at the same coffee shop, there would be no reason for them not to form a company and take legal ownership of their work, and seek compensation for distributing it.

THE HOLE HAWG OF OPERATING SYSTEMS

Unix has always lurked provocatively in the background of the operating system wars, like the Russian Army. Most people know it only by reputation, and its reputation, as the Dilbert cartoon suggests, is mixed. But everyone seems to agree that if it could only get its act together and stop surrendering vast tracts of rich agricultural land and hundreds of thousands of prisoners of war to the onrushing invaders, it could stomp them (and all other opposition) flat.

It is difficult to explain how Unix has earned this respect without going into mind-smashing technical detail. Perhaps the gist of it can be explained by telling a story about drills.

The Hole Hawg is a drill made by the Milwaukee Tool Company. If you look in a typical hardware store you may find smaller Milwaukee drills but not the Hole Hawg, which is too powerful and too expensive for homeowners. The Hole Hawg does not have the pistol-like design of a cheap homeowner's drill. It is a cube of solid metal with a handle sticking out of one face and a chuck mounted in another. The cube contains a disconcertingly potent electric motor. You can hold the handle and operate the trigger with your index finger, but unless you are exceptionally strong you cannot control the weight of the Hole Hawg with one hand; it is a two-hander all the way. In order to fight off the counter-torque of the Hole Hawg you use a separate handle (provided), which you screw into one side of the iron cube or the other depending on whether you are using your left or right hand to operate the trigger. This handle is not a sleek, ergonomically designed item as it would be in a homeowner's drill. It is simply a foot-long chunk of regular galvanized pipe, threaded on one end, with a black rubber handle on the other. If you lose it, you just go to the local plumbing supply store and buy another chunk of pipe.

During the Eighties I did some construction work. One day, another worker leaned a ladder against the outside of the building that we were putting up, climbed up to the second-story level, and used the Hole Hawg to drill a hole through the exterior wall. At some point, the drill bit caught in the wall. The Hole Hawg, following its one and only imperative, kept going. It spun the worker's body around like a rag doll, causing him to knock his own ladder down. Fortunately he kept his grip on the Hole Hawg, which remained lodged in the wall, and he simply dangled from it and shouted for help until someone came along and reinstated the ladder.

I myself used a Hole Hawg to drill many holes through studs, which it did as a blender chops cabbage. I also used it to cut a few six-inch-diameter holes through an old lath-and-plaster ceiling. I chucked in a new hole saw, went up to the second story, reached down between the newly installed floor joists, and began to cut through the first-floor ceiling below. Where my homeowner's drill had labored and whined to spin the huge bit around, and had stalled at the slightest obstruction, the Hole Hawg rotated with the stupid consistency of a spinning planet. When the hole saw seized up, the Hole Hawg spun itself and me around, and crushed one of my hands between the steel pipe handle and a joist, producing a few lacerations, each surrounded by a wide corona of deeply bruised flesh. It also bent the hole saw itself, though not so badly that I couldn't use it. After a few such run-ins, when I got ready to use the Hole Hawg my heart actually began to pound with atavistic terror.

But I never blamed the Hole Hawg; I blamed myself. The Hole Hawg is dangerous because it does exactly what you tell it to. It is not bound by the physical limitations that are inherent in a cheap drill, and neither is it limited by safety interlocks that might be built into a homeowner's product by a liability-conscious manufacturer. The danger lies not in the machine itself but in the user's failure to envision the full consequences of the instructions he gives to it.

A smaller tool is dangerous too, but for a completely different reason: it tries to do what you tell it to, and fails in some way that is unpredictable and almost always undesirable. But the Hole Hawg is like the genie of the ancient fairy tales, who carries out his master's instructions literally and precisely and with unlimited power, often with disastrous, unforeseen consequences.

Pre-Hole Hawg, I used to examine the drill selection in hardware stores with what I thought was a judicious eye, scorning the smaller low-end models and hefting the big expensive ones appreciatively, wishing I could afford one of them babies. Now I view them all with such contempt that I do not even consider them to be real drills--merely scaled-up toys designed to exploit the self-delusional tendencies of soft-handed homeowners who want to believe that they have purchased an actual tool. Their plastic casings, carefully designed and focus-group-tested to convey a feeling of solidity and power, seem disgustingly flimsy and cheap to me, and I am ashamed that I was ever bamboozled into buying such knicknacks.

It is not hard to imagine what the world would look like to someone who had been raised by contractors and who had never used any drill other than a Hole Hawg. Such a person, presented with the best and most expensive hardware-store drill, would not even recognize it as such. He might instead misidentify it as a child's toy, or some kind of motorized screwdriver. If a salesperson or a deluded homeowner referred to it as a drill, he would laugh and tell them that they were mistaken--they simply had their terminology wrong. His interlocutor would go away irritated, and probably feeling rather defensive about his basement full of cheap, dangerous, flashy, colorful tools.

Unix is the Hole Hawg of operating systems, and Unix hackers, like Doug Barnes and the guy in the Dilbert cartoon and many of the other people who populate Silicon Valley, are like contractor's sons who grew up using only Hole Hawgs. They might use Apple/Microsoft OSes to write letters, play video games, or balance their checkbooks, but they cannot really bring themselves to take these operating systems seriously.

This is an entertaining and memorable comparison, but makes a few tacit assumptions about what an operating system is for. In the old days an OS was hard to look at by anyone except a seasoned professional, and though the kludgy greenscreen prompt now has a certain retro appeal to the fashion conscious (thank you, Wachowski brothers), its initial obtuseness as a user interface has left an unfortunate stain on the layman's concept of an operating system. While an operating system is, strictly speaking, a set of software and firmware that makes the computer 'operate', a more sensible and modern definition would be that an operating system 'helps a computer be useful to a human'. And the user interface of an operating system plays an integral part of that.

On my laptop I have a program called iPhoto. I also have a program called Photoshop. When I'm looking at pictures in iPhoto, arranged in a grid pattern, I can easily find the ones I want to work with. To open them with Photoshop, I just click on the miniature pictures, and drag them over to the Photoshop icon. While it's true that a computer is not a light-table in a darkroom, it's also true that a computer is not, at it's core, a blinking green cursor in front of a square-bracket. Once you apply a kind of 'cultural relativism', it becomes apparent that whether a user interface is graphical or text, icons or symbols, one window or many, the only determining factor in its appropriateness for a computer is its appropriateness for the kind of work you would have a computer do. And a computer can do lots, and lots, and lots of things. Adjust fuel mixtures in a car, steer an ocean liner, slap humans around at chess, or completely wreck a nice beach, for example.

UNIX could, indeed, be considered the 'hole hawg' of operating systems. But while its core reliability is unmatched, its default interface - the command prompt - has a learning-curve like a brick wall. Reliably executing a task is actually the final step of a much longer process. That process heavily involves a human, and consists of describing to the computer what the task is. Once you move beyond a few basic file and network operations, complex tasks at a command prompt inevitably involve scripting, macros, interlinking programs spraying data at each other, debuggers, crafty pattern matching, tangled strings of arguments, and eventually, compilers, hardware tomfoolery, and foul language. Once it's all set up and debugged, of course, it runs very fast and reliably. But how many brains had to fry along the way? Just how many brains, Mister President?

Those who have survived a product development cycle at the command line are tough indeed. They have a right to brag -- their calloused hands have mastered the 'hole hawg'. But while these swaggering macho types would scoff at anything but bare metal on the surface of their power tools, more reasonable people come to appreciate the helpful aspects of, say, a molded rubber grip, or milled edges that won't lacerate a workman's fingers. What's more powerful, a hole-hawg, or a five-speed consumer drill with large grips, a safety shut-off, and a built-in level? The hole-hawg, obviously. But which would you rather use to drill, say, five hundred chandelier mounts in a ballroom?

Though at first glance a handheld drill is for drilling a hole, it's not really. A handheld drill is for helping a human drill a hole. Milled edges and rubber grips are part of its User Interface, and should not be discounted as frivolous. A built-in level - usually an air bubble trapped in a transparent green tube, bolted on the side of the drill - may also appear to be frippery. May even appear to be 'mixing the metaphor' of what a drill actually does. Yet it has proven to be a helpful part of a drill's User Interface.

Which brings me to a more important point about so-called metaphor shear: What determines the basis for it? Should the metaphor of a User Interface for a drill be created around the innards of a drill - or the uses to which a drill is applied? And if people use a computer to edit documents, the same way they used to use a typewriter, what does it matter that the innards of a computer are vastly different than the innards of a typewriter? Even users of typwriters, by and large, didn't know how the thing worked. They just pounded keys onto paper. Their real understanding of a typewriter was based on what came out the other end - a printed document. That a computer has no paper, just dancing light patterns, is a fact pretty obvious to any writer who sits down at one, and a fact that has immediate implications. Nonetheless the computer can be used to accomplish the same task: Word processing.

Users of typewriters will be more productive on a UI that's based on the metaphor of documents, typeset text, page layout, cursors, etc, because that metaphor precisely matches the work they need to get done. Not necessarily the typewriter whose primordial nature dictated it! While it's true that your document would evaporate like a wisp of smoke on a computer with buggy software, crappy components, no autosave, no battery-backup, and a power outage, there has been constant progress in all of these realms to make word processing on a computer more reliable than with a typewriter. (You can, for example, store your document in ten places at once automatically, over a vast network, preserving all your words even if your house burns down and your office floods.) Just as paper and ink were continuously engineered to not fade into pulpy haze after a few hours in the open air, computer word processing has evolved as well.

So perhaps what Stephenson calls metaphor shear, should actually be called equipment shear. Good UI across generations of equipment keeps the metaphor intact. A side-effect of good UI design on a computer is that people can put it to work without having to understand everything that goes on under the hood. This side effect, combined with bad engineering, has caused a lot of disasters when the equipment itself - not the metaphor - breaks down. So let's call a spade a spade, and say that lots of computers out there are cheap pieces of garbage that blow at the first power surge, faint at the first coffee spill, or crack up when their lousy cooling fans fly apart. You could install the 'hole hawg of operating systems' onto one, but it would be like using an original 'hole hawg' with bad batteries and a cardboard drill bit.

Of course, that would still be an improvement, since most computers are still running Windows 95.

THE ORAL TRADITION

Unix is hard to learn. The process of learning it is one of multiple small epiphanies. Typically you are just on the verge of inventing some necessary tool or utility when you realize that someone else has already invented it, and built it in, and this explains some odd file or directory or command that you have noticed but never really understood before.

For example there is a command (a small program, part of the OS) called whoami, which enables you to ask the computer who it thinks you are. On a Unix machine, you are always logged in under some name--possibly even your own! What files you may work with, and what software you may use, depends on your identity. When I started out using Linux, I was on a non-networked machine in my basement, with only one user account, and so when I became aware of the whoami command it struck me as ludicrous. But once you are logged in as one person, you can temporarily switch over to a pseudonym in order to access different files. If your machine is on the Internet, you can log onto other computers, provided you have a user name and a password. At that point the distant machine becomes no different in practice from the one right in front of you. These changes in identity and location can easily become nested inside each other, many layers deep, even if you aren't doing anything nefarious. Once you have forgotten who and where you are, the whoami command is indispensible. I use it all the time.

The file systems of Unix machines all have the same general structure. On your flimsy operating systems, you can create directories (folders) and give them names like Frodo or My Stuff and put them pretty much anywhere you like. But under Unix the highest level--the root--of the filesystem is always designated with the single character "/" and it always contains the same set of top-level directories:

/usr

/etc

/var

/bin

/proc

/boot

/home

/root

/sbin

/dev

/lib

/tmp

and each of these directories typically has its own distinct structure of subdirectories. Note the obsessive use of abbreviations and avoidance of capital letters; this is a system invented by people to whom repetitive stress disorder is what black lung is to miners. Long names get worn down to three-letter nubbins, like stones smoothed by a river.

This is not the place to try to explain why each of the above directories exists, and what is contained in it. At first it all seems obscure; worse, it seems deliberately obscure. When I started using Linux I was accustomed to being able to create directories wherever I wanted and to give them whatever names struck my fancy. Under Unix you are free to do that, of course (you are free to do anything) but as you gain experience with the system you come to understand that the directories listed above were created for the best of reasons and that your life will be much easier if you follow along (within /home, by the way, you have pretty much unlimited freedom).

This description also reveals the way a programmer is forced to work, when his interface is the command line. When you must communicate all your instructions as carefully typed symbols, context and brevity are paramount.

After this kind of thing has happened several hundred or thousand times, the hacker understands why Unix is the way it is, and agrees that it wouldn't be the same any other way. It is this sort of acculturation that gives Unix hackers their confidence in the system, and the attitude of calm, unshakable, annoying superiority captured in the Dilbert cartoon. Windows 95 and MacOS are products, contrived by engineers in the service of specific companies. Unix, by contrast, is not so much a product as it is a painstakingly compiled oral history of the hacker subculture. It is our Gilgamesh epic.

In the 1990's, UNIX definitely stood in contrast to Windows and Mac OS. The GUI-based paradigm of computer interaction was an all-or-nothing proposition, since the OS products that offered a GUI had no legacy of back-doors or secret panels that allowed access to their inner workings. You had to pay no attention to the man behind the curtain, because there was no way to tear the curtain aside. Even if he wrecked your nice beach.

Windows and Mac OS users suffered from this in another way, too. An operating system that does not have to be usable from a command-line does not have to be designed as carefully. To make a command-line environment useful, you need to have access to very discreet components and functions in the operating system. To allow such access, an OS developer must break complex systems up into many more small, self-contained, modular parts, which must all be capable of the subtle re-routings and recombinations that are a serious hacker's bread-and-butter.

Providing that kind of access takes a lot of development time. At least a decade of it, apparently. Microsoft, the largest and most powerful software developer on Earth, couldn't get beyond the most rudimentary command-line interface for at least ten years. Unwilling to cede control to the UNIX platform, but knowing that they had to offer something like it, they poured billions of dollars into re-inventing the wheel. They drilled down from their GUI, into the guts of their OS, and cultivated a jungle of scripting languages on top of it. (From the head-cracking syntax and cancerous integration of Visual Basic, to the NT Recovery Console, to the disorienting and short-lived J-Script, and a dozen variants in between.)

If you're a UNIX or Linux user, on any platform, in any common shell, you get a folder listing by typing "ls". (Though you can alias that to anything at all with a simple command.) The command-line that exists in Windows XP is a complete re-write of a complete re-write of an emulation of the primeval DOS shell that Windows 3.1 was built on top of. There is absolutely no reason why the developers at Microsoft couldn't have, at any point along this process of re-writes, inserted an "ls" command that gave a folder listing, just to make it a little easier for those UNIX guys. Just to make them feel at home.

And yet, in Windows XP Pro, Service Pack 2, a product of nearly 20 years of development up in Redmond, you get a folder listing by typing "dir". Period. "ls" spits an error message at you. That, in a nutshell, is Microsoft's uniquely proprietary attitude.

(Handily, an unrelated group of developers have created a series of freely distributed components called Cygwin, that among many other things, rights this moronic wrong.)

But back to the point at hand: The 1990's contrast of GUI versus command-line. The two types of interface were never mutually exclusive, they just started that way. Though it would be years before they grew together, the eventual synthesis was a natural one. It took place mostly in the UNIX universe (Windows 3.1, the worst possible GUI on top of the worst possible command-line, was such an egregious hack-job that it doesn't count), with the rise of a dozen bustling window-managers, each securely fastened to the underlying command-line, but lacking in design and usability for various reasons. Microsoft didn't want to compete by licensing any of these -- it was more their style to steal the ideas, and recreate the code in-house. But Apple Computer and Steve Jobs took a different approach. They threw their entire operating system in the trash can, emptied it (from the Special menu), and created a window-manager in it's image. They borrowed heavily from modern design principles (and licensed code from modern developers), and built their window-manager on top of a long-tested, highly-componentized, well-secured OS. A variant of UNIX, of course. A command-line OS. Of course.

What made old epics like Gilgamesh so powerful and so long-lived was that they were living bodies of narrative that many people knew by heart, and told over and over again--making their own personal embellishments whenever it struck their fancy. The bad embellishments were shouted down, the good ones picked up by others, polished, improved, and, over time, incorporated into the story. Likewise, Unix is known, loved, and understood by so many hackers that it can be re-created from scratch whenever someone needs it. This is very difficult to understand for people who are accustomed to thinking of OSes as things that absolutely have to be bought.

Later on in this essay, Neal will argue that a decade of cruftsmanship results in an ailing operating system, and the best approach is to toss the code and rewrite it from scratch. The flaw in that argument is that a decade of cruft also means a decade of testing. To put it another way, a tree that has overgrown and become a tangled mess still has one crucial advantage over a sapling: Deep roots. Prune it way back, and you've got an excellent foundation for new growth.

Many hackers have launched more or less successful re-implementations of the Unix ideal. Each one brings in new embellishments. Some of them die out quickly, some are merged with similar, parallel innovations created by different hackers attacking the same problem, others still are embraced, and adopted into the epic. Thus Unix has slowly accreted around a simple kernel and acquired a kind of complexity and asymmetry about it that is organic, like the roots of a tree, or the branchings of a coronary artery. Understanding it is more like anatomy than physics.

For at least a year, prior to my adoption of Linux, I had been hearing about it. Credible, well-informed people kept telling me that a bunch of hackers had got together an implentation of Unix that could be downloaded, free of charge, from the Internet. For a long time I could not bring myself to take the notion seriously. It was like hearing rumors that a group of model rocket enthusiasts had created a completely functional Saturn V by exchanging blueprints on the Net and mailing valves and flanges to each other.

But it's true. Credit for Linux generally goes to its human namesake, one Linus Torvalds, a Finn who got the whole thing rolling in 1991 when he used some of the GNU tools to write the beginnings of a Unix kernel that could run on PC-compatible hardware. And indeed Torvalds deserves all the credit he has ever gotten, and a whole lot more. But he could not have made it happen by himself, any more than Richard Stallman could have. To write code at all, Torvalds had to have cheap but powerful development tools, and these he got from Stallman's GNU project.

And he had to have cheap hardware on which to write that code. Cheap hardware is a much harder thing to arrange than cheap software; a single person (Stallman) can write software and put it up on the Net for free, but in order to make hardware it's necessary to have a whole industrial infrastructure, which is not cheap by any stretch of the imagination. Really the only way to make hardware cheap is to punch out an incredible number of copies of it, so that the unit cost eventually drops. For reasons already explained, Apple had no desire to see the cost of hardware drop. The only reason Torvalds had cheap hardware was Microsoft.

Microsoft refused to go into the hardware business, insisted on making its software run on hardware that anyone could build, and thereby created the market conditions that allowed hardware prices to plummet. In trying to understand the Linux phenomenon, then, we have to look not to a single innovator but to a sort of bizarre Trinity: Linus Torvalds, Richard Stallman, and Bill Gates. Take away any of these three and Linux would not exist.

Sure it would. It would have just popped up a few years later, and it would have been called "Frankux", or "Martinux", or maybe "Trentux". The net is vast and infinite.

OS SHOCK

Young Americans who leave their great big homogeneous country and visit some other part of the world typically go through several stages of culture shock: first, dumb wide-eyed astonishment. Then a tentative engagement with the new country's manners, cuisine, public transit systems and toilets, leading to a brief period of fatuous confidence that they are instant experts on the new country. As the visit wears on, homesickness begins to set in, and the traveler begins to appreciate, for the first time, how much he or she took for granted at home. At the same time it begins to seem obvious that many of one's own cultures and traditions are essentially arbitrary, and could have been different; driving on the right side of the road, for example. When the traveler returns home and takes stock of the experience, he or she may have learned a good deal more about America than about the country they went to visit.

For the same reasons, Linux is worth trying. It is a strange country indeed, but you don't have to live there; a brief sojourn suffices to give some flavor of the place and--more importantly--to lay bare everything that is taken for granted, and all that could have been done differently, under Windows or MacOS.

You can't try it unless you install it. With any other OS, installing it would be a straightforward transaction: in exchange for money, some company would give you a CD-ROM, and you would be on your way. But a lot is subsumed in that kind of transaction, and has to be gone through and picked apart.

We like plain dealings and straightforward transactions in America. If you go to Egypt and, say, take a taxi somewhere, you become a part of the taxi driver's life; he refuses to take your money because it would demean your friendship, he follows you around town, and weeps hot tears when you get in some other guy's taxi. You end up meeting his kids at some point, and have to devote all sort of ingenuity to finding some way to compensate him without insulting his honor. It is exhausting. Sometimes you just want a simple Manhattan-style taxi ride.

But in order to have an American-style setup, where you can just go out and hail a taxi and be on your way, there must exist a whole hidden apparatus of medallions, inspectors, commissions, and so forth--which is fine as long as taxis are cheap and you can always get one. When the system fails to work in some way, it is mysterious and infuriating and turns otherwise reasonable people into conspiracy theorists. But when the Egyptian system breaks down, it breaks down transparently. You can't get a taxi, but your driver's nephew will show up, on foot, to explain the problem and apologize.

Microsoft and Apple do things the Manhattan way, with vast complexity hidden behind a wall of interface. Linux does things the Egypt way, with vast complexity strewn about all over the landscape. If you've just flown in from Manhattan, your first impulse will be to throw up your hands and say "For crying out loud! Will you people get a grip on yourselves!?" But this does not make friends in Linux-land any better than it would in Egypt.

This used to be the case in the 1990's, but Apple and Microsoft have changed the nature of the game, each in their distinctive ways. Now it's a Manhattan-style system, that breaks down transparently. If you want to know why your big shiny OS X calendar widget broke down, you can launch the Console Log app and view fifty pages of debug dumps, if you're so inclined. You can grab an open-source Calendar app, tweak the config files, and use that instead. If you want greater control, you can download the complete developers' toolkit for free, and get busy hacking.

You can suck Linux right out of the air, as it were, by downloading the right files and putting them in the right places, but there probably are not more than a few hundred people in the world who could create a functioning Linux system in that way. What you really need is a distribution of Linux, which means a prepackaged set of files. But distributions are a separate thing from Linux per se.

Linux per se is not a specific set of ones and zeroes, but a self-organizing Net subculture. The end result of its collective lucubrations is a vast body of source code, almost all written in C (the dominant computer programming language). "Source code" just means a computer program as typed in and edited by some hacker. If it's in C, the file name will probably have .c or .cpp on the end of it, depending on which dialect was used; if it's in some other language it will have some other suffix. Frequently these sorts of files can be found in a directory with the name /src which is the hacker's Hebraic abbreviation of "source."

Source files are useless to your computer, and of little interest to most users, but they are of gigantic cultural and political significance, because Microsoft and Apple keep them secret while Linux makes them public. They are the family jewels. They are the sort of thing that in Hollywood thrillers is used as a McGuffin: the plutonium bomb core, the top-secret blueprints, the suitcase of bearer bonds, the reel of microfilm. If the source files for Windows or MacOS were made public on the Net, then those OSes would become free, like Linux--only not as good, because no one would be around to fix bugs and answer questions. Linux is "open source" software meaning, simply, that anyone can get copies of its source code files.

Your computer doesn't want source code any more than you do; it wants object code. Object code files typically have the suffix .o and are unreadable all but a few, highly strange humans, because they consist of ones and zeroes. Accordingly, this sort of file commonly shows up in a directory with the name /bin, for "binary."

Source files are simply ASCII text files. ASCII denotes a particular way of encoding letters into bit patterns. In an ASCII file, each character has eight bits all to itself. This creates a potential "alphabet" of 256 distinct characters, in that eight binary digits can form that many unique patterns. In practice, of course, we tend to limit ourselves to the familiar letters and digits. The bit-patterns used to represent those letters and digits are the same ones that were physically punched into the paper tape by my high school teletype, which in turn were the same one used by the telegraph industry for decades previously. ASCII text files, in other words, are telegrams, and as such they have no typographical frills. But for the same reason they are eternal, because the code never changes, and universal, because every text editing and word processing software ever written knows about this code.

A lesson that all those developers of vanity-programming-languages, laced with Unicode symbols, should keep in mind.

Therefore just about any software can be used to create, edit, and read source code files. Object code files, then, are created from these source files by a piece of software called a compiler, and forged into a working application by another piece of software called a linker.

The triad of editor, compiler, and linker, taken together, form the core of a software development system. Now, it is possible to spend a lot of money on shrink-wrapped development systems with lovely graphical user interfaces and various ergonomic enhancements. In some cases it might even be a good and reasonable way to spend money. But on this side of the road, as it were, the very best software is usually the free stuff. Editor, compiler and linker are to hackers what ponies, stirrups, and archery sets were to the Mongols. Hackers live in the saddle, and hack on their own tools even while they are using them to create new applications. It is quite inconceivable that superior hacking tools could have been created from a blank sheet of paper by product engineers. Even if they are the brightest engineers in the world they are simply outnumbered.

This depends on whether you're hacking to develop an application, or hacking to take someone else's application apart. For the latter, espionage is the name of the game, and the internet commons is always the best place to look. But if you're a developer (sudden vision of Steve Ballmer slapping his fist), you have two essential sources: The official documentation as maintained by the incorporated publisher of the OS (Be that Microsoft, Apple, IBM, Sony, Palm One, or Nintendo), and the online support forums and personal blogs of your peers. For answers about what APIs do what, your most consistent reference will be the official docs (it sure beats deciphering the source code to the OS yourself). For help when things go wrong, which they will, the community is where you look. This community exists whether the OS, or language, is proprietary or open-source.

Furthermore, having access to the source code of an OS, a compiler, or a language interpreter, does NOT guarantee that that OS, compiler, or language will be easier to develop on. You want easy to develop on? Try Cocoa, Flash, or BASIC. Want an instant headache? Try Visual Basic, Javascript+DHTML, or 3D shading-engine pseudocode.

In the GNU/Linux world there are two major text editing programs: the minimalist vi (known in some implementations as elvis) and the maximalist emacs. I use emacs, which might be thought of as a thermonuclear word processor. It was created by Richard Stallman; enough said. It is written in Lisp, which is the only computer language that is beautiful. It is colossal, and yet it only edits straight ASCII text files, which is to say, no fonts, no boldface, no underlining. In other words, the engineer-hours that, in the case of Microsoft Word, were devoted to features like mail merge, and the ability to embed feature-length motion pictures in corporate memoranda, were, in the case of emacs, focused with maniacal intensity on the deceptively simple-seeming problem of editing text. If you are a professional writer--i.e., if someone else is getting paid to worry about how your words are formatted and printed--emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish. For page layout and printing you can use TeX: a vast corpus of typesetting lore written in C and also available on the Net for free.

Well someone's got a woody. Emacs Makes A Computer Slow, you know.

I could say a lot about emacs and TeX, but right now I am trying to tell a story about how to actually install Linux on your machine. The hard-core survivalist approach would be to download an editor like emacs, and the GNU Tools--the compiler and linker--which are polished and excellent to the same degree as emacs. Equipped with these, one would be able to start downloading ASCII source code files (/src) and compiling them into binary object code files (/bin) that would run on the machine. But in order to even arrive at this point--to get emacs running, for example--you have to have Linux actually up and running on your machine. And even a minimal Linux operating system requires thousands of binary files all acting in concert, and arranged and linked together just so.

Several entities have therefore taken it upon themselves to create "distributions" of Linux. If I may extend the Egypt analogy slightly, these entities are a bit like tour guides who meet you at the airport, who speak your language, and who help guide you through the initial culture shock. If you are an Egyptian, of course, you see it the other way; tour guides exist to keep brutish outlanders from traipsing through your mosques and asking you the same questions over and over and over again.

Some of these tour guides are commercial organizations, such as Red Hat Software, which makes a Linux distribution called Red Hat that has a relatively commercial sheen to it. In most cases you put a Red Hat CD-ROM into your PC and reboot and it handles the rest. Just as a tour guide in Egypt will expect some sort of compensation for his services, commercial distributions need to be paid for. In most cases they cost almost nothing and are well worth it.

I use a distribution called Debian (the word is a contraction of "Deborah" and "Ian") which is non-commercial. It is organized (or perhaps I should say "it has organized itself") along the same lines as Linux in general, which is to say that it consists of volunteers who collaborate over the Net, each responsible for looking after a different chunk of the system. These people have broken Linux down into a number of packages, which are compressed files that can be downloaded to an already functioning Debian Linux system, then opened up and unpacked using a free installer application. Of course, as such, Debian has no commercial arm--no distribution mechanism. You can download all Debian packages over the Net, but most people will want to have them on a CD-ROM. Several different companies have taken it upon themselves to decoct all of the current Debian packages onto CD-ROMs and then sell them. I buy mine from Linux Systems Labs. The cost for a three-disc set, containing Debian in its entirety, is less than three dollars. But (and this is an important distinction) not a single penny of that three dollars is going to any of the coders who created Linux, nor to the Debian packagers. It goes to Linux Systems Labs and it pays, not for the software, or the packages, but for the cost of stamping out the CD-ROMs.

Every Linux distribution embodies some more or less clever hack for circumventing the normal boot process and causing your computer, when it is turned on, to organize itself, not as a PC running Windows, but as a "host" running Unix. This is slightly alarming the first time you see it, but completely harmless. When a PC boots up, it goes through a little self-test routine, taking an inventory of available disks and memory, and then begins looking around for a disk to boot up from. In any normal Windows computer that disk will be a hard drive. But if you have your system configured right, it will look first for a floppy or CD-ROM disk, and boot from that if one is available.

Linux exploits this chink in the defenses. Your computer notices a bootable disk in the floppy or CD-ROM drive, loads in some object code from that disk, and blindly begins to execute it. But this is not Microsoft or Apple code, this is Linux code, and so at this point your computer begins to behave very differently from what you are accustomed to. Cryptic messages began to scroll up the screen. If you had booted a commercial OS, you would, at this point, be seeing a "Welcome to MacOS" cartoon, or a screen filled with clouds in a blue sky, and a Windows logo. But under Linux you get a long telegram printed in stark white letters on a black screen. There is no "welcome!" message. Most of the telegram has the semi-inscrutable menace of graffiti tags.

That's how I know it's superior! I can see the dazzling complexity! It's such a thrill, being privy to the thousands of complex and fascinating instructions that a computer must follow, at my behest! Especially since none of it is in any way related to the task I hope to accomplish with this device!

The only parts of this that are readable, for normal people, are the error messages and warnings. And yet it's noteworthy that Linux doesn't stop, or crash, when it encounters an error; it spits out a pithy complaint, gives up on whatever processes were damaged, and keeps on rolling. This was decidedly not true of the early versions of Apple and Microsoft OSes, for the simple reason that an OS that is not capable of walking and chewing gum at the same time cannot possibly recover from errors. Looking for, and dealing with, errors requires a separate process running in parallel with the one that has erred. A kind of superego, if you will, that keeps an eye on all of the others, and jumps in when one goes astray. Now that MacOS and Windows can do more than one thing at a time they are much better at dealing with errors than they used to be, but they are not even close to Linux or other Unices in this respect; and their greater complexity has made them vulnerable to new types of errors.

FALLIBILITY, ATONEMENT, REDEMPTION, TRUST, AND OTHER ARCANE TECHNICAL CONCEPTS

Linux is not capable of having any centrally organized policies dictating how to write error messages and documentation, and so each programmer writes his own. Usually they are in English even though tons of Linux programmers are Europeans. Frequently they are funny. Always they are honest. If something bad has happened because the software simply isn't finished yet, or because the user screwed something up, this will be stated forthrightly. The command line interface makes it easy for programs to dribble out little comments, warnings, and messages here and there. Even if the application is imploding like a damaged submarine, it can still usually eke out a little S.O.S. message. Sometimes when you finish working with a program and shut it down, you find that it has left behind a series of mild warnings and low-grade error messages in the command-line interface window from which you launched it. As if the software were chatting to you about how it was doing the whole time you were working with it.

Documentation, under Linux, comes in the form of man (short for manual) pages. You can access these either through a GUI (xman) or from the command line (man). Here is a sample from the man page for a program called rsh:

"Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here."

The man pages contain a lot of such material, which reads like the terse mutterings of pilots wrestling with the controls of damaged airplanes. The general feel is of a thousand monumental but obscure struggles seen in the stop-action light of a strobe. Each programmer is dealing with his own obstacles and bugs; he is too busy fixing them, and improving the software, to explain things at great length or to maintain elaborate pretensions.

Elaborate pretensions and proper documentation are not the same thing. Once again, what does this amusing archeology have to do with GETTING OUR WORK DONE?

In practice you hardly ever encounter a serious bug while running Linux. When you do, it is almost always with commercial software (several vendors sell software that runs under Linux). The operating system and its fundamental utility programs are too important to contain serious bugs. I have been running Linux every day since late 1995 and have seen many application programs go down in flames, but I have never seen the operating system crash. Never. Not once. There are quite a few Linux systems that have been running continuously and working hard for months or years without needing to be rebooted.

Commercial OSes have to adopt the same official stance towards errors as Communist countries had towards poverty. For doctrinal reasons it was not possible to admit that poverty was a serious problem in Communist countries, because the whole point of Communism was to eradicate poverty. Likewise, commercial OS companies like Apple and Microsoft can't go around admitting that their software has bugs and that it crashes all the time, any more than Disney can issue press releases stating that Mickey Mouse is an actor in a suit.

This is a problem, because errors do exist and bugs do happen. Every few months Bill Gates tries to demo a new Microsoft product in front of a large audience only to have it blow up in his face. Commercial OS vendors, as a direct consequence of being commercial, are forced to adopt the grossly disingenuous position that bugs are rare aberrations, usually someone else's fault, and therefore not really worth talking about in any detail. This posture, which everyone knows to be absurd, is not limited to press releases and ad campaigns. It informs the whole way these companies do business and relate to their customers. If the documentation were properly written, it would mention bugs, errors, and crashes on every single page. If the on-line help systems that come with these OSes reflected the experiences and concerns of their users, they would largely be devoted to instructions on how to cope with crashes and errors.

But this does not happen. Joint stock corporations are wonderful inventions that have given us many excellent goods and services. They are good at many things. Admitting failure is not one of them. Hell, they can't even admit minor shortcomings.

Actually this is not true. The bulk of published discourse about the development and status of an operating system is for the benefit of application developers. Not stockholders. That such communication can be terse and unhelpful is not a deliberate attempt to hide anything, but is actually a problem that engineers have always struggled to address. Engineers are sometimes not the best writers.

Just imagine what kind of hell software development was like before the internet was popularized. You got all your technical documentation from thick inscrutable manuals, hopelessly out of date, combined with hideously expensive conference calls. The internet has brought amazing changes for developers. It's like the difference between being lost alone at sea with a rowboat in a hurricane, and being ensconced on the deck of a cruise liner with cabins stuffed full of your fellow engineers. Modern database-driven bug tracking programs, all cross-connected through the internet, have made things even better.

Of course, this behavior is not as pathological in a corporation as it would be in a human being. Most people, nowadays, understand that corporate press releases are issued for the benefit of the corporation's shareholders and not for the enlightenment of the public. Sometimes the results of this institutional dishonesty can be dreadful, as with tobacco and asbestos. In the case of commercial OS vendors it is nothing of the kind, of course; it is merely annoying.

Some might argue that consumer annoyance, over time, builds up into a kind of hardened plaque that can conceal serious decay, and that honesty might therefore be the best policy in the long run; the jury is still out on this in the operating system market. The business is expanding fast enough that it's still much better to have billions of chronically annoyed customers than millions of happy ones.

Nowadays it's a matter of diminishing returns for the bigwigs. As Neal says, software is ephemeral. Once it's reasonably bug-free, it's hard to convince your user-base to pay for the next upgrade. Now give them better hardware, on the other hand...

(As an aside, clever analysts have noted that this is the reason Apple does not sell a computer whose CPU can be removed and upgraded, and probably never will again.)

Most system administrators I know who work with Windows NT all the time agree that when it hits a snag, it has to be re-booted, and when it gets seriously messed up, the only way to fix it is to re-install the operating system from scratch. Or at least this is the only way that they know of to fix it, which amounts to the same thing. It is quite possible that the engineers at Microsoft have all sorts of insider knowledge on how to fix the system when it goes awry, but if they do, they do not seem to be getting the message out to any of the actual system administrators I know.

Because Linux is not commercial--because it is, in fact, free, as well as rather difficult to obtain, install, and operate--it does not have to maintain any pretensions as to its reliability. Consequently, it is much more reliable. When something goes wrong with Linux, the error is noticed and loudly discussed right away. Anyone with the requisite technical knowledge can go straight to the source code and point out the source of the error, which is then rapidly fixed by whichever hacker has carved out responsibility for that particular program.

This doesn't really hold water. Linux is a solid core surrounded by a constantly changing hurricane of sawdust. That core is small. The various and sundry sawdust grains are small as well, because a loose-knit cabal of enthusiasts can only handle a job of so much complexity before it starts to develop faults that would take very serious coordination, and very serious internal changes, to eliminate. This phenomenon works in tandem with the task-oriented nature of many programmers. Specifically, once they have written a program, or knit together a series of programs, that accomplishes their task, they often lose interest in the project. So software either succumbs to feature bloat like an overzealous hermit crab, or it evolves into something else completely, shedding old features and UI along the way until it can no longer easily accomplish the few tasks it was initially designed to handle.

There are a few things that combat this sawdust malaise of coding. One of them is the profit-driven structure of a businesses' engineering department. If they need a program to accomplish a task, or they want to produce a program to help others accomplish a task, the impetus of profit from a task accomplished will drive them to persevere through the growing pains of an application, all the way through the documentation process that is so often abdicated in the online world. Whether they take the resulting code and make it open-source, or whether they develop it with the participation of the outside world, is up to them, and is an unrelated issue. The point to be made here is that the impetus of profit will actually produce better code in the end.

The second thing that combats this sawdust phenomenon is good old-fashioned zealotry. If you've carved out a chunk of code for your very own, or become fascinated with the efficient accomplishment of a task, or even if you're on a crusade to trounce the efforts of some corporation you don't approve of, you will donate a lot of energy to your cause and those big nasty systemic bugs will get squeezed out. Hence: OpenOffice.org, the WINE project, and (more or less) The Gimp.

I think the thing that geeks didn't foresee, and the thing that may bother them in retrospect, is that these personal, political, or hacker-esque motivations for the open-source community can actually be separated from the process of open-source development itself. Large companies CAN, in fact, appropriate chunks of open-source code, add to them, build on them, create a useful application, turn a profit with that application, and then release all the necessary code to the public domain. Oceans of hackers pounding out open standards and clever apps have not, and will not, topple the swaggering giants of the computer industry, or even of the software industry. Microsoft's exaggerated reaction to the 'threat' of Linux has just planted that hip scenario into the fertile brains of outsiders.

As far as I know, Debian is the only Linux distribution that has its own constitution (http://www.debian.org/devel/constitution), but what really sold me on it was its phenomenal bug database (http://www.debian.org/Bugs), which is a sort of interactive Doomsday Book of error, fallibility, and redemption. It is simplicity itself. When had a problem with Debian in early January of 1997, I sent in a message describing the problem to submit@bugs.debian.org. My problem was promptly assigned a bug report number (#6518) and a severity level (the available choices being critical, grave, important, normal, fixed, and wishlist) and forwarded to mailing lists where Debian people hang out. Within twenty-four hours I had received five e-mails telling me how to fix the problem: two from North America, two from Europe, and one from Australia. All of these e-mails gave me the same suggestion, which worked, and made my problem go away. But at the same time, a transcript of this exchange was posted to Debian's bug database, so that if other users had the same problem later, they would be able to search through and find the solution without having to enter a new, redundant bug report.

Contrast this with the experience that I had when I tried to install Windows NT 4.0 on the very same machine about ten months later, in late 1997. The installation program simply stopped in the middle with no error messages. I went to the Microsoft Support website and tried to perform a search for existing help documents that would address my problem. The search engine was completely nonfunctional; it did nothing at all. It did not even give me a message telling me that it was not working.

Eventually I decided that my motherboard must be at fault; it was of a slightly unusual make and model, and NT did not support as many different motherboards as Linux. I am always looking for excuses, no matter how feeble, to buy new hardware, so I bought a new motherboard that was Windows NT logo-compatible, meaning that the Windows NT logo was printed right on the box. I installed this into my computer and got Linux running right away, then attempted to install Windows NT again. Again, the installation died without any error message or explanation. By this time a couple of weeks had gone by and I thought that perhaps the search engine on the Microsoft Support website might be up and running. I gave that a try but it still didn't work.

So I created a new Microsoft support account, then logged on to submit the incident. I supplied my product ID number when asked, and then began to follow the instructions on a series of help screens. In other words, I was submitting a bug report just as with the Debian bug tracking system. It's just that the interface was slicker--I was typing my complaint into little text-editing boxes on Web forms, doing it all through the GUI, whereas with Debian you send in an e-mail telegram. I knew that when I was finished submitting the bug report, it would become proprietary Microsoft information, and other users wouldn't be able to see it. Many Linux users would refuse to participate in such a scheme on ethical grounds, but I was willing to give it a shot as an experiment. In the end, though I was never able to submit my bug report, because the series of linked web pages that I was filling out eventually led me to a completely blank page: a dead end.

So I went back and clicked on the buttons for "phone support" and eventually was given a Microsoft telephone number. When I dialed this number I got a series of piercing beeps and a recorded message from the phone company saying "We're sorry, your call cannot be completed as dialed."

I tried the search page again--it was still completely nonfunctional. Then I tried PPI (Pay Per Incident) again. This led me through another series of Web pages until I dead-ended at one reading: "Notice-there is no Web page matching your request."

I tried it again, and eventually got to a Pay Per Incident screen reading: "OUT OF INCIDENTS. There are no unused incidents left in your account. If you would like to purchase a support incident, click OK-you will then be able to prepay for an incident...." The cost per incident was $95.

The experiment was beginning to seem rather expensive, so I gave up on the PPI approach and decided to have a go at the FAQs posted on Microsoft's website. None of the available FAQs had anything to do with my problem except for one entitled "I am having some problems installing NT" which appeared to have been written by flacks, not engineers.

So I gave up and still, to this day, have never gotten Windows NT installed on that particular machine. For me, the path of least resistance was simply to use Debian Linux.

In the world of open source software, bug reports are useful information. Making them public is a service to other users, and improves the OS. Making them public systematically is so important that highly intelligent people voluntarily put time and money into running bug databases. In the commercial OS world, however, reporting a bug is a privilege that you have to pay lots of money for. But if you pay for it, it follows that the bug report must be kept confidential--otherwise anyone could get the benefit of your ninety-five bucks! And yet nothing prevents NT users from setting up their own public bug database.

This is, in other words, another feature of the OS market that simply makes no sense unless you view it in the context of culture. What Microsoft is selling through Pay Per Incident isn't technical support so much as the continued illusion that its customers are engaging in some kind of rational business transaction. It is a sort of routine maintenance fee for the upkeep of the fantasy. If people really wanted a solid OS they would use Linux, and if they really wanted tech support they would find a way to get it; Microsoft's customers want something else.

This somewhat paranoid description doesn't acknowledge the engineering issues involved. Just because a particular company's tech-support systems are inefficient, doesn't mean that the inefficiency is deliberate. (And if you think Microsoft is bad, try getting tech support for, say, bad cell-phone coverage, your DVD player, or the programmable functions of your microwave.) After all, why attribute to malice what you can attribute to stupidity? Microsoft customers just plain don't know that there is an alternative. Through the 1990's Linux had a relative advertising budget of just about zero dollars.

As of this writing (Jan. 1999), something like 32,000 bugs have been reported to the Debian Linux bug database. Almost all of them have been fixed a long time ago. There are twelve "critical" bugs still outstanding, of which the oldest was posted 79 days ago. There are 20 outstanding "grave" bugs of which the oldest is 1166 days old. There are 48 "important" bugs and hundreds of "normal" and less important ones.

Likewise, BeOS (which I'll get to in a minute) has its own bug database (http://www.be.com/developers/bugs/index.html) with its own classification system, including such categories as "Not a Bug," "Acknowledged Feature," and "Will Not Fix." Some of the "bugs" here are nothing more than Be hackers blowing off steam, and are classified as "Input Acknowledged." For example, I found one that was posted on December 30th, 1998. It's in the middle of a long list of bugs, wedged between one entitled "Mouse working in very strange fashion" and another called "Change of BView frame does not affect, if BView not attached to a BWindow."

This one is entitled

R4: BeOS missing megalomaniacal figurehead to harness and focus developer rage

and it goes like this:

Be Status: Input Acknowledged

BeOS Version: R3.2

Component: unknown

Full Description:

The BeOS needs a megalomaniacal egomaniac sitting on its throne to give it a human character which everyone loves to hate. Without this, the BeOS will languish in the impersonifiable realm of OSs that people can never quite get a handle on. You can judge the success of an OS not by the quality of its features, but by how infamous and disliked the leaders behind them are.

I believe this is a side-effect of developer comraderie under miserable conditions. After all, misery loves company. I believe that making the BeOS less conceptually accessible and far less reliable will require developers to band together, thus developing the kind of community where strangers talk to one- another, kind of like at a grocery store before a huge snowstorm.

Following this same program, it will likely be necessary to move the BeOS headquarters to a far-less-comfortable climate. General environmental discomfort will breed this attitude within and there truly is no greater recipe for success. I would suggest Seattle, but I think it's already taken. You might try Washington, DC, but definitely not somewhere like San Diego or Tucson.

Unfortunately, the Be bug reporting system strips off the names of the people who report the bugs (to protect them from retribution!?) and so I don't know who wrote this.

So it would appear that I'm in the middle of crowing about the technical and moral superiority of Debian Linux. But as almost always happens in the OS world, it's more complicated than that. I have Windows NT running on another machine, and the other day (Jan. 1999), when I had a problem with it, I decided to have another go at Microsoft Support. This time the search engine actually worked (though in order to reach it I had to identify myself as "advanced"). And instead of coughing up some useless FAQ, it located about two hundred documents (I was using very vague search criteria) that were obviously bug reports--though they were called something else. Microsoft, in other words, has got a system up and running that is functionally equivalent to Debian's bug database. It looks and feels different, of course, but it contains technical nitty-gritty and makes no bones about the existence of errors.

As I've explained, selling OSes for money is a basically untenable position, and the only way Apple and Microsoft can get away with it is by pursuing technological advancements as aggressively as they can, and by getting people to believe in, and to pay for, a particular image: in the case of Apple, that of the creative free thinker, and in the case of Microsoft, that of the respectable techno-bourgeois. Just like Disney, they're making money from selling an interface, a magic mirror. It has to be polished and seamless or else the whole illusion is ruined and the business plan vanishes like a mirage.

Not exactly, in the case of Apple. As Mr. Stephenson explained earlier, Apple sells hardware. Their OS is primarily an incentive for that. They understand this very well, in fact. Their online music service, and free Windows music player, both exist for the sole purpose of selling more Apple hardware (the iPod). They created a web browser from open-source material, and released it as a free component of their OS, for the sole purpose of enhancing hardware sales. Same with their various other productivity apps. In fact it's become increasingly apparent that Apple is not in the same business as Microsoft at all. They only intersect when it brings profit for their particular markets. Hardware for Apple (iPod, Servers), software for Microsoft (Office, MSN).

Accordingly, it was the case until recently that the people who wrote manuals and created customer support websites for commercial OSes seemed to have been barred, by their employers' legal or PR departments, from admitting, even obliquely, that the software might contain bugs or that the interface might be suffering from the blinking twelve problem. They couldn't address users' actual difficulties. The manuals and websites were therefore useless, and caused even technically self-assured users to wonder whether they were going subtly insane.

When Apple engages in this sort of corporate behavior, one wants to believe that they are really trying their best. We all want to give Apple the benefit of the doubt, because mean old Bill Gates kicked the crap out of them, and because they have good PR. But when Microsoft does it, one almost cannot help becoming a paranoid conspiracist. Obviously they are hiding something from us! And yet they are so powerful! They are trying to drive us crazy!

Cute, but inaccurate. Once again - never attribute to malice that which can be adequately explained by stupidity. The Microsoft corporate structure just wasn't designed to make the process of identifying and fixing bugs a process that involves the end-user. The marketing department is what gets to talk to the end-user, not -- good grief! -- the engineering department! The last thing they'd want is for those Dilbert clones opening their honest mouths!

This approach to dealing with one's customers was straight out of the Central European totalitarianism of the mid-Twentieth Century. The adjectives "Kafkaesque" and "Orwellian" come to mind. It couldn't last, any more than the Berlin Wall could, and so now Microsoft has a publicly available bug database. It's called something else, and it takes a while to find it, but it's there.

They have, in other words, adapted to the two-tiered Eloi/Morlock structure of technological society. If you're an Eloi you install Windows, follow the instructions, hope for the best, and dumbly suffer when it breaks. If you're a Morlock you go to the website, tell it that you are "advanced," find the bug database, and get the truth straight from some anonymous Microsoft engineer.

But once Microsoft has taken this step, it raises the question, once again, of whether there is any point to being in the OS business at all. Customers might be willing to pay $95 to report a problem to Microsoft if, in return, they get some advice that no other user is getting. This has the useful side effect of keeping the users alienated from one another, which helps maintain the illusion that bugs are rare aberrations. But once the results of those bug reports become openly available on the Microsoft website, everything changes. No one is going to cough up $95 to report a problem when chances are good that some other sucker will do it first, and that instructions on how to fix the bug will then show up, for free, on a public website. And as the size of the bug database grows, it eventually becomes an open admission, on Microsoft's part, that their OSes have just as many bugs as their competitors'. There is no shame in that; as I mentioned, Debian's bug database has logged 32,000 reports so far. But it puts Microsoft on an equal footing with the others and makes it a lot harder for their customers--who want to believe--to believe.

MEMENTO MORI

Once the Linux machine has finished spitting out its jargonic opening telegram, it prompts me to log in with a user name and a password. At this point the machine is still running the command line interface, with white letters on a black screen. There are no windows, menus, or buttons. It does not respond to the mouse; it doesn't even know that the mouse is there. It is still possible to run a lot of software at this point. Emacs, for example, exists in both a CLI and a GUI version (actually there are two GUI versions, reflecting some sort of doctrinal schism between Richard Stallman and some hackers who got fed up with him). The same is true of many other Unix programs. Many don't have a GUI at all, and many that do are capable of running from the command line.

Of course, since my computer only has one monitor screen, I can only see one command line, and so you might think that I could only interact with one program at a time. But if I hold down the Alt key and then hit the F2 function button at the top of my keyboard, I am presented with a fresh, blank, black screen with a login prompt at the top of it. I can log in here and start some other program, then hit Alt-F1 and go back to the first screen, which is still doing whatever it was when I left it. Or I can do Alt-F3 and log in to a third screen, or a fourth, or a fifth. On one of these screens I might be logged in as myself, on another as root (the system administrator), on yet another I might be logged on to some other computer over the Internet.

Each of these screens is called, in Unix-speak, a tty, which is an abbreviation for teletype. So when I use my Linux system in this way I am going right back to that small room at Ames High School where I first wrote code twenty-five years ago, except that a tty is quieter and faster than a teletype, and capable of running vastly superior software, such as emacs or the GNU development tools.

It is easy (easy by Unix, not Apple/Microsoft standards) to configure a Linux machine so that it will go directly into a GUI when you boot it up. This way, you never see a tty screen at all. I still have mine boot into the white-on-black teletype screen however, as a computational memento mori. It used to be fashionable for a writer to keep a human skull on his desk as a reminder that he was mortal, that all about him was vanity. The tty screen reminds me that the same thing is true of slick user interfaces.

As I stated before, a GUI is not just eye-candy and damaging metaphor shear. A GUI, when designed appropriately and suited to the task at hand, promotes efficiency and functionality.

The X Windows System, which is the GUI of Unix, has to be capable of running on hundreds of different video cards with different chipsets, amounts of onboard memory, and motherboard buses. Likewise, there are hundreds of different types of monitors on the new and used market, each with different specifications, and so there are probably upwards of a million different possible combinations of card and monitor. The only thing they all have in common is that they all work in VGA mode, which is the old command-line screen that you see for a few seconds when you launch Windows. So Linux always starts in VGA, with a teletype interface, because at first it has no idea what sort of hardware is attached to your computer. In order to get beyond the glass teletype and into the GUI, you have to tell Linux exactly what kinds of hardware you have. If you get it wrong, you'll get a blank screen at best, and at worst you might actually destroy your monitor by feeding it signals it can't handle.

When I started using Linux this had to be done by hand. I once spent the better part of a month trying to get an oddball monitor to work for me, and filled the better part of a composition book with increasingly desperate scrawled notes. Nowadays, most Linux distributions ship with a program that automatically scans the video card and self-configures the system, so getting X Windows up and running is nearly as easy as installing an Apple/Microsoft GUI. The crucial information goes into a file (an ASCII text file, naturally) called XF86Config, which is worth looking at even if your distribution creates it for you automatically. For most people it looks like meaningless cryptic incantations, which is the whole point of looking at it. An Apple/Microsoft system needs to have the same information in order to launch its GUI, but it's apt to be deeply hidden somewhere, and it's probably in a file that can't even be opened and read by a text editor. All of the important files that make Linux systems work are right out in the open. They are always ASCII text files, so you don't need special tools to read them. You can look at them any time you want, which is good, and you can mess them up and render your system totally dysfunctional, which is not so good.

"Special tools" is a tricky phrase. Even simple text files are worthless if there's no program around that will display them for you -- a situation that low-level device programmers can still find themselves in. Luckily, even a basic UNIX install comes with several programs for viewing text. Why aren't these considered "special tools", compared to, say, "regedit" on Microsoft Windows?

The answer reaffirms a guiding principle of command-line systems: In them, data is best manipulated as generic streams of keyboard-accessible symbols. ASCII text files. As long as your data is a text file, you can pipe it, sort it, search it, wrangle it, and mangle it, with a few clever commands. The programs involved are not "special tools", because they are fundamental to all command-line work.

Regedit, installed with Windows, is not such a fundamental program. You can use Windows all day long and (hopefully) never invoke Regedit. You can't really enhance your computer with it, unless you count fixing mistakes made by other badly-written software -- but on the upside, Regedit is a powerful tool for helping you render your system inopereable, which may lead to a Linux installation.

On the other side of the fence, OS X stores configuration data in XML files. You could read them with a text editor, but in most cases, you wouldn't want to.

At any rate, assuming that my XF86Config file is just so, I enter the command "startx" to launch the X Windows System. The screen blanks out for a minute, the monitor makes strange twitching noises, then reconstitutes itself as a blank gray desktop with a mouse cursor in the middle. At the same time it is launching a window manager. X Windows is pretty low-level software; it provides the infrastructure for a GUI, and it's a heavy industrial infrastructure. But it doesn't do windows. That's handled by another category of application that sits atop X Windows, called a window manager. Several of these are available, all free of course. The classic is twm (Tom's Window Manager) but there is a smaller and supposedly more efficient variant of it called fvwm, which is what I use. I have my eye on a completely different window manager called Enlightenment, which may be the hippest single technology product I have ever seen, in that (a) it is for Linux, (b) it is freeware, (c) it is being developed by a very small number of obsessed hackers, and (d) it looks amazingly cool; it is the sort of window manager that might show up in the backdrop of an Aliens movie.

Beware software choices made on the basis of hip-ness. Your time is more valuable than your allegorical hips.

Anyway, the window manager acts as an intermediary between X Windows and whatever software you want to use. It draws the window frames, menus, and so on, while the applications themselves draw the actual content in the windows. The applications might be of any sort: text editors, Web browsers, graphics packages, or utility programs, such as a clock or calculator. In other words, from this point on, you feel as if you have been shunted into a parallel universe that is quite similar to the familiar Apple or Microsoft one, but slightly and pervasively different. The premier graphics program under Apple/Microsoft is Adobe Photoshop, but under Linux it's something called The GIMP. Instead of the Microsoft Office Suite, you can buy something called ApplixWare. Many commercial software packages, such as Mathematica, Netscape Communicator, and Adobe Acrobat, are available in Linux versions, and depending on how you set up your window manager you can make them look and behave just as they would under MacOS or Windows.

But there is one type of window you'll see on Linux GUI that is rare or nonexistent under other OSes. These windows are called "xterm" and contain nothing but lines of text--this time, black text on a white background, though you can make them be different colors if you choose. Each xterm window is a separate command line interface--a tty in a window. So even when you are in full GUI mode, you can still talk to your Linux machine through a command-line interface.

*cough* OS X

There are many good pieces of Unix software that do not have GUIs at all. This might be because they were developed before X Windows was available, or because the people who wrote them did not want to suffer through all the hassle of creating a GUI, or because they simply do not need one. In any event, those programs can be invoked by typing their names into the command line of an xterm window. The whoami command, mentioned earlier, is a good example. There is another called wc ("word count") which simply returns the number of lines, words, and characters in a text file.

The ability to run these little utility programs on the command line is a great virtue of Unix, and one that is unlikely to be duplicated by pure GUI operating systems. The wc command, for example, is the sort of thing that is easy to write with a command line interface. It probably does not consist of more than a few lines of code, and a clever programmer could probably write it in a single line. In compiled form it takes up just a few bytes of disk space. But the code required to give the same program a graphical user interface would probably run into hundreds or even thousands of lines, depending on how fancy the programmer wanted to make it. Compiled into a runnable piece of software, it would have a large overhead of GUI code. It would be slow to launch and it would use up a lot of memory. This would simply not be worth the effort, and so "wc" would never be written as an independent program at all. Instead users would have to wait for a word count feature to appear in a commercial software package.

GUIs tend to impose a large overhead on every single piece of software, even the smallest, and this overhead completely changes the programming environment. Small utility programs are no longer worth writing. Their functions, instead, tend to get swallowed up into omnibus software packages.

Nowadays we have new tools to consider, such as Apple's Interface Builder, and the object-oriented paradigms that they embrace. These days it's actually LESS efficient to develop a command-line driven app than a windowed one, provided you're familiar with the tools. Because of this, the whole argument about GUI being a detriment to efficiency - programmer or end-user - is becoming obsolete. Note that we still hold one truth to be self-evident: A programmer will always work faster in the language that he or she is most familiar with.

As GUIs get more complex, and impose more and more overhead, this tendency becomes more pervasive, and the software packages grow ever more colossal; after a point they begin to merge with each other, as Microsoft Word and Excel and PowerPoint have merged into Microsoft Office: a stupendous software Wal-Mart sitting on the edge of a town filled with tiny shops that are all boarded up.

It is an unfair analogy, because when a tiny shop gets boarded up it means that some small shopkeeper has lost his business. Of course nothing of the kind happens when "wc" becomes subsumed into one of Microsoft Word's countless menu items. The only real drawback is a loss of flexibility for the user, but it is a loss that most customers obviously do not notice or care about. The most serious drawback to the Wal-Mart approach is that most users only want or need a tiny fraction of what is contained in these giant software packages. The remainder is clutter, dead weight. And yet the user in the next cubicle over will have completely different opinions as to what is useful and what isn't.

The problem here is, we're taking poor design decisions about Microsoft's "office productivity" app, and blaming those decisions on the limitations of the GUI. Just because Microsoft had to find new ball-busting ways to convince their besotted corporate customers that another round of paid upgrades would make their business function better, doesn't mean that GUI and software bloat are the same thing.

Actually, the biggest problem with software bloat in MS Office is their deliberate mucking of their own file format, in order to confound the developers of competing word processing apps. If they'd left their fucking file-format human readable like PDF was supposed to be, or used a standard like XML, or even maintained their own open standard, you could actually have your cake and eat it too. You could throw together a basic "wc" utility in about ten minutes (the proper libraries would be downloadable, or included with your dev tools), plus or minus debugging time, and happily dump your Word file onto the icon, and have the word count appear in a window. Or you could invoke it via command-line instead.

And speaking of software bloat:

The other important thing to mention, here, is that Microsoft has included a genuinely cool feature in the Office package: a Basic programming package. Basic is the first computer language that I learned, back when I was using the paper tape and the teletype. By using the version of Basic that comes with Office you can write your own little utility programs that know how to interact with all of the little doohickeys, gewgaws, bells, and whistles in Office. Basic is easier to use than the languages typically employed in Unix command-line programming, and Office has reached many, many more people than the GNU tools. And so it is quite possible that this feature of Office will, in the end, spawn more hacking than GNU.

Well it's certainly spawned ... more VIRUSES than ANY OTHER FEATURE IN THE HISTORY OF SOFTWARE. Heh heh heh.

But now I'm talking about application software, not operating systems. And as I've said, Microsoft's application software tends to be very good stuff. I don't use it very much, because I am nowhere near their target market. If Microsoft ever makes a software package that I use and like, then it really will be time to dump their stock, because I am a market segment of one.

GEEK FATIGUE

Over the years that I've been working with Linux I have filled three and a half notebooks logging my experiences. I only begin writing things down when I'm doing something complicated, like setting up X Windows or fooling around with my Internet connection, and so these notebooks contain only the record of my struggles and frustrations. When things are going well for me, I'll work along happily for many months without jotting down a single note. So these notebooks make for pretty bleak reading. Changing anything under Linux is a matter of opening up various of those little ASCII text files and changing a word here and a character there, in ways that are extremely significant to how the system operates.

Many of the files that control how Linux operates are nothing more than command lines that became so long and complicated that not even Linux hackers could type them correctly. When working with something as powerful as Linux, you can easily devote a full half-hour to engineering a single command line. For example, the "find" command, which searches your file system for files that match certain criteria, is fantastically powerful and general. Its "man" is eleven pages long, and these are pithy pages; you could easily expand them into a whole book. And if that is not complicated enough in and of itself, you can always pipe the output of one Unix command to the input of another, equally complicated one. The "pon" command, which is used to fire up a PPP connection to the Internet, requires so much detailed information that it is basically impossible to launch it entirely from the command line. Instead you abstract big chunks of its input into three or four different files. You need a dialing script, which is effectively a little program telling it how to dial the phone and respond to various events; an options file, which lists up to about sixty different options on how the PPP connection is to be set up; and a secrets file, giving information about your password.

Presumably there are godlike Unix hackers somewhere in the world who don't need to use these little scripts and options files as crutches, and who can simply pound out fantastically complex command lines without making typographical errors and without having to spend hours flipping through documentation. But I'm not one of them. Like almost all Linux users, I depend on having all of those details hidden away in thousands of little ASCII text files, which are in turn wedged into the recesses of the Unix filesystem. When I want to change something about the way my system works, I edit those files. I know that if I don't keep track of every little change I've made, I won't be able to get your system back in working order after I've gotten it all messed up. Keeping hand-written logs is tedious, not to mention kind of anachronistic. But it's necessary.

Once again, we need to keep our eye on the ball. We need to keep asking, HOW DOES ANY OF THIS HELP US ACCOMPLISH OUR TASKS?

I probably could have saved myself a lot of headaches by doing business with a company called Cygnus Support, which exists to provide assistance to users of free software. But I didn't, because I wanted to see if I could do it myself. The answer turned out to be yes, but just barely. And there are many tweaks and optimizations that I could probably make in my system that I have never gotten around to attempting, partly because I get tired of being a Morlock some days, and partly because I am afraid of fouling up a system that generally works well.

Though Linux works for me and many other users, its sheer power and generality is its Achilles' heel. If you know what you are doing, you can buy a cheap PC from any computer store, throw away the Windows discs that come with it, turn it into a Linux system of mind-boggling complexity and power. You can hook it up to twelve other Linux boxes and make it into part of a parallel computer. You can configure it so that a hundred different people can be logged onto it at once over the Internet, via as many modem lines, Ethernet cards, TCP/IP sockets, and packet radio links. You can hang half a dozen different monitors off of it and play DOOM with someone in Australia while tracking communications satellites in orbit and controlling your house's lights and thermostats and streaming live video from your web-cam and surfing the Net and designing circuit boards on the other screens. But the sheer power and complexity of the system--the qualities that make it so vastly technically superior to other OSes--sometimes make it seem too formidable for routine day-to-day use.

This should have been the starting point of a long discussion about usability, and the relationship between the complexity of the task, the complexity of the tool, and the complexity of the interface. Since it wasn't, I covered it earlier.

Sometimes, in other words, I just want to go to Disneyland.

The ideal OS for me would be one that had a well-designed GUI that was easy to set up and use, but that included terminal windows where I could revert to the command line interface, and run GNU software, when it made sense. A few years ago, Be Inc. invented exactly that OS. It is called the BeOS.

$this_section =~ s/BeOS/OS X/gs;

ETRE

Many people in the computer business have had a difficult time grappling with Be, Incorporated, for the simple reason that nothing about it seems to make any sense whatsoever. It was launched in late 1990, which makes it roughly contemporary with Linux. From the beginning it has been devoted to creating a new operating system that is, by design, incompatible with all the others (though, as we shall see, it is compatible with Unix in some very important ways). If a definition of "celebrity" is someone who is famous for being famous, then Be is an anti-celebrity. It is famous for not being famous; it is famous for being doomed. But it has been doomed for an awfully long time.

The internet makes all doom relative.

Be's mission might make more sense to hackers than to other people. In order to explain why I need to explain the concept of cruft, which, to people who write code, is nearly as abhorrent as unnecessary repetition.

If you've been to San Francisco you may have seen older buildings that have undergone "seismic upgrades," which frequently means that grotesque superstructures of modern steelwork are erected around buildings made in, say, a Classical style. When new threats arrive--if we have an Ice Age, for example--additional layers of even more high-tech stuff may be constructed, in turn, around these, until the original building is like a holy relic in a cathedral--a shard of yellowed bone enshrined in half a ton of fancy protective junk.

Analogous measures can be taken to keep creaky old operating systems working. It happens all the time. Ditching an worn-out old OS ought to be simplified by the fact that, unlike old buildings, OSes have no aesthetic or cultural merit that makes them intrinsically worth saving. But it doesn't work that way in practice. If you work with a computer, you have probably customized your "desktop," the environment in which you sit down to work every day, and spent a lot of money on software that works in that environment, and devoted much time to familiarizing yourself with how it all works. This takes a lot of time, and time is money. As already mentioned, the desire to have one's interactions with complex technologies simplified through the interface, and to surround yourself with virtual tchotchkes and lawn ornaments, is natural and pervasive--presumably a reaction against the complexity and formidable abstraction of the computer world. Computers give us more choices than we really want. We prefer to make those choices once, or accept the defaults handed to us by software companies, and let sleeping dogs lie. But when an OS gets changed, all the dogs jump up and start barking.

The average computer user is a technological antiquarian who doesn't really like things to change. He or she is like an urban professional who has just bought a charming fixer-upper and is now moving the furniture and knicknacks around, and reorganizing the kitchen cupboards, so that everything's just right. If it is necessary for a bunch of engineers to scurry around in the basement shoring up the foundation so that it can support the new cast-iron claw-foot bathtub, and snaking new wires and pipes through the walls to supply modern appliances, why, so be it--engineers are cheap, at least when millions of OS users split the cost of their services.

Likewise, computer users want to have the latest Pentium in their machines, and to be able to surf the web, without messing up all the stuff that makes them feel as if they know what the hell is going on. Sometimes this is actually possible. Adding more RAM to your system is a good example of an upgrade that is not likely to screw anything up.

Alas, very few upgrades are this clean and simple. Lawrence Lessig, the whilom Special Master in the Justice Department's antitrust suit against Microsoft, complained that he had installed Internet Explorer on his computer, and in so doing, lost all of his bookmarks--his personal list of signposts that he used to navigate through the maze of the Internet. It was as if he'd bought a new set of tires for his car, and then, when pulling away from the garage, discovered that, owing to some inscrutable side-effect, every signpost and road map in the world had been destroyed. If he's like most of us, he had put a lot of work into compiling that list of bookmarks. This is only a small taste of the sort of trouble that upgrades can cause. Crappy old OSes have value in the basically negative sense that changing to new ones makes us wish we'd never been born.

All of the fixing and patching that engineers must do in order to give us the benefits of new technology without forcing us to think about it, or to change our ways, produces a lot of code that, over time, turns into a giant clot of bubble gum, spackle, baling wire and duct tape surrounding every operating system. In the jargon of hackers, it is called "cruft." An operating system that has many, many layers of it is described as "crufty." Hackers hate to do things twice, but when they see something crufty, their first impulse is to rip it out, throw it away, and start anew.

If Mark Twain were brought back to San Francisco today and dropped into one of these old seismically upgraded buildings, it would look just the same to him, with all the doors and windows in the same places--but if he stepped outside, he wouldn't recognize it. And--if he'd been brought back with his wits intact--he might question whether the building had been worth going to so much trouble to save. At some point, one must ask the question: is this really worth it, or should we maybe just tear it down and put up a good one? Should we throw another human wave of structural engineers at stabilizing the Leaning Tower of Pisa, or should we just let the damn thing fall over and build a tower that doesn't suck?

Like an upgrade to an old building, cruft always seems like a good idea when the first layers of it go on--just routine maintenance, sound prudent management. This is especially true if (as it were) you never look into the cellar, or behind the drywall. But if you are a hacker who spends all his time looking at it from that point of view, cruft is fundamentally disgusting, and you can't avoid wanting to go after it with a crowbar. Or, better yet, simply walk out of the building--let the Leaning Tower of Pisa fall over--and go make a new one THAT DOESN'T LEAN.

This analogy begs the question: Who can afford to scrap everything? It also doesn't work very well in the programming world, when a new release of an old app can have no new features, but can have a thousand bugs fixed, and be unilaterally better.

For a long time it was obvious to Apple, Microsoft, and their customers that the first generation of GUI operating systems was doomed, and that they would eventually need to be ditched and replaced with completely fresh ones. During the late Eighties and early Nineties, Apple launched a few abortive efforts to make fundamentally new post-Mac OSes such as Pink and Taligent. When those efforts failed they launched a new project called Copland which also failed. In 1997 they flirted with the idea of acquiring Be, but instead they acquired Next, which has an OS called NextStep that is, in effect, a variant of Unix. As these efforts went on, and on, and on, and failed and failed and failed, Apple's engineers, who were among the best in the business, kept layering on the cruft. They were gamely trying to turn the little toaster into a multi-tasking, Internet-savvy machine, and did an amazingly good job of it for a while--sort of like a movie hero running across a jungle river by hopping across crocodiles' backs. But in the real world you eventually run out of crocodiles, or step on a really smart one.

And using OS 9 was like taking a hike in the Everglades. OS X was a welcome rescue, even the half-baked version 10.0. And yet this was not an example of abandoning everything -- Apple went back to an operating system whose legacy predated their own.

Speaking of which, Microsoft tackled the same problem in a considerably more orderly way by creating a new OS called Windows NT, which is explicitly intended to be a direct competitor of Unix. NT stands for "New Technology" which might be read as an explicit rejection of cruft. And indeed, NT is reputed to be a lot less crufty than what MacOS eventually turned into; at one point the documentation needed to write code on the Mac filled something like 24 binders. Windows 95 was, and Windows 98 is, crufty because they have to be backward-compatible with older Microsoft OSes. Linux deals with the cruft problem in the same way that Eskimos supposedly dealt with senior citizens: if you insist on using old versions of Linux software, you will sooner or later find yourself drifting through the Bering Straits on a dwindling ice floe. They can get away with this because most of the software is free, so it costs nothing to download up-to-date versions, and because most Linux users are Morlocks.

The great idea behind BeOS was to start from a clean sheet of paper and design an OS the right way. And that is exactly what they did. This was obviously a good idea from an aesthetic standpoint, but does not a sound business plan make. Some people I know in the GNU/Linux world are annoyed with Be for going off on this quixotic adventure when their formidable skills could have been put to work helping to promulgate Linux.

Indeed, none of it makes sense until you remember that the founder of the company, Jean-Louis Gassee, is from France--a country that for many years maintained its own separate and independent version of the English monarchy at a court in St. Germaines, complete with courtiers, coronation ceremonies, a state religion and a foreign policy. Now, the same annoying yet admirable stiff-neckedness that gave us the Jacobites, the force de frappe, Airbus, and ARRET signs in Quebec, has brought us a really cool operating system. I fart in your general direction, Anglo-Saxon pig-dogs!

The above paragraph is why Neal Stephenson kicks ass.

To create an entirely new OS from scratch, just because none of the existing ones was exactly right, struck me as an act of such colossal nerve that I felt compelled to support it. I bought a BeBox as soon as I could. The BeBox was a dual-processor machine, powered by Motorola chips, made specifically to run the BeOS; it could not run any other operating system. That's why I bought it. I felt it was a way to burn my bridges. Its most distinctive feature is two columns of LEDs on the front panel that zip up and down like tachometers to convey a sense of how hard each processor is working. I thought it looked cool, and besides, I reckoned that when the company went out of business in a few months, my BeBox would be a valuable collector's item.

Now it is about two years later and I am typing this on my BeBox. The LEDs (Das Blinkenlights, as they are called in the Be community) flash merrily next to my right elbow as I hit the keys. Be, Inc. is still in business, though they stopped making BeBoxes almost immediately after I bought mine. They made the sad, but probably quite wise decision that hardware was a sucker's game, and ported the BeOS to Macintoshes and Mac clones. Since these used the same sort of Motorola chips that powered the BeBox, this wasn't especially hard.

Very soon afterwards, Apple strangled the Mac-clone makers and restored its hardware monopoly. So, for a while, the only new machines that could run BeOS were made by Apple.

By this point Be, like Spiderman with his Spider-sense, had developed a keen sense of when they were about to get crushed like a bug. Even if they hadn't, the notion of being dependent on Apple--so frail and yet so vicious--for their continued existence should have put a fright into anyone. Now engaged in their own crocodile-hopping adventure, they ported the BeOS to Intel chips--the same chips used in Windows machines. And not a moment too soon, for when Apple came out with its new top-of-the-line hardware, based on the Motorola G3 chip, they withheld the technical data that Be's engineers would need to make the BeOS run on those machines. This would have killed Be, just like a slug between the eyes, if they hadn't made the jump to Intel.

So now BeOS runs on an assortment of hardware that is almost incredibly motley: BeBoxes, aging Macs and Mac orphan-clones, and Intel machines that are intended to be used for Windows. Of course the latter type are ubiquitous and shockingly cheap nowadays, so it would appear that Be's hardware troubles are finally over. Some German hackers have even come up with a Das Blinkenlights replacement: it's a circuit board kit that you can plug into PC-compatible machines running BeOS. It gives you the zooming LED tachometers that were such a popular feature of the BeBox.

My BeBox is already showing its age, as all computers do after a couple of years, and sooner or later I'll probably have to replace it with an Intel machine. Even after that, though, I will still be able to use it. Because, inevitably, someone has now ported Linux to the BeBox.

At any rate, BeOS has an extremely well-thought-out GUI built on a technological framework that is solid. It is based from the ground up on modern object-oriented software principles. BeOS software consists of quasi-independent software entities called objects, which communicate by sending messages to each other. The OS itself is made up of such objects, and serves as a kind of post office or Internet that routes messages to and fro, from object to object. The OS is multi-threaded, which means that like all other modern OSes it can walk and chew gum at the same time; but it gives programmers a lot of power over spawning and terminating threads, or independent sub-processes. It is also a multi-processing OS, which means that it is inherently good at running on computers that have more than one CPU (Linux and Windows NT can also do this proficiently).

(So can the firmware in my neighbor's electric toothbrush)

For this user, a big selling point of BeOS is the built-in Terminal application, which enables you to open up windows that are equivalent to the xterm windows in Linux. In other words, the command line interface is available if you want it. And because BeOS hews to a certain standard called POSIX, it is capable of running most of the GNU software. That is to say that the vast array of command-line software developed by the GNU crowd will work in BeOS terminal windows without complaint. This includes the GNU development tools-the compiler and linker. And it includes all of the handy little utility programs. I'm writing this using a modern sort of user-friendly text editor called Pe, written by a Dutchman named Maarten Hekkelman, but when I want to find out how long it is, I jump to a terminal window and run "wc."

As is suggested by the sample bug report I quoted earlier, people who work for Be, and developers who write code for BeOS, seem to be enjoying themselves more than their counterparts in other OSes. They also seem to be a more diverse lot in general. A couple of years ago I went to an auditorium at a local university to see some representatives of Be put on a dog-and-pony show. I went because I assumed that the place would be empty and echoing, and I felt that they deserved an audience of at least one. In fact, I ended up standing in an aisle, for hundreds of students had packed the place. It was like a rock concert. One of the two Be engineers on the stage was a black man, which unfortunately is a very odd thing in the high-tech world. The other made a ringing denunciation of cruft, and extolled BeOS for its cruft-free qualities, and actually came out and said that in ten or fifteen years, when BeOS had become all crufty like MacOS and Windows 95, it would be time to simply throw it away and create a new OS from scratch. I doubt that this is an official Be, Inc. policy, but it sure made a big impression on everyone in the room! During the late Eighties, the MacOS was, for a time, the OS of cool people-artists and creative-minded hackers-and BeOS seems to have the potential to attract the same crowd now. Be mailing lists are crowded with hackers with names like Vladimir and Olaf and Pierre, sending flames to each other in fractured techno-English.

The only real question about BeOS is whether or not it is doomed.

The answer to that question may matter to investors, but is often moot for end-users and freeware developers.

Of late, Be has responded to the tiresome accusation that they are doomed with the assertion that BeOS is "a media operating system" made for media content creators, and hence is not really in competition with Windows at all. This is a little bit disingenuous. To go back to the car dealership analogy, it is like the Batmobile dealer claiming that he is not really in competition with the others because his car can go three times as fast as theirs and is also capable of flying.

Be has an office in Paris, and, as mentioned, the conversation on Be mailing lists has a strongly European flavor. At the same time they have made strenuous efforts to find a niche in Japan, and Hitachi has recently begun bundling BeOS with their PCs. So if I had to make wild guess I'd say that they are playing Go while Microsoft is playing chess. They are staying clear, for now, of Microsoft's overwhelmingly strong position in North America. They are trying to get themselves established around the edges of the board, as it were, in Europe and Japan, where people may be more open to alternative OSes, or at least more hostile to Microsoft, than they are in the United States.

What holds Be back in this country is that the smart people are afraid to look like suckers. You run the risk of looking naive when you say "I've tried the BeOS and here's what I think of it." It seems much more sophisticated to say "Be's chances of carving out a new niche in the highly competitive OS market are close to nil."

No, what held Be back in this country is that they were a solution looking for a problem. Microsoft's OS was obviously flawed, but it was "good enough" to those with no exposure to the alternatives. Several billion dollars of advertising money would have helped Be with the exposure, but then they would have needed more billions just to pry hardware manufacturers out of the contractual grip of Microsoft. A superior OS is worth a lot of money ... but the interest on a 15 billion dollar loan will kill you.

It is, in techno-speak, a problem of mindshare. And in the OS business, mindshare is more than just a PR issue; it has direct effects on the technology itself. All of the peripheral gizmos that can be hung off of a personal computer--the printers, scanners, PalmPilot interfaces, and Lego Mindstorms--require pieces of software called drivers. Likewise, video cards and (to a lesser extent) monitors need drivers. Even the different types of motherboards on the market relate to the OS in different ways, and separate code is required for each one. All of this hardware-specific code must not only written but also tested, debugged, upgraded, maintained, and supported. Because the hardware market has become so vast and complicated, what really determines an OS's fate is not how good the OS is technically, or how much it costs, but rather the availability of hardware-specific code. Linux hackers have to write that code themselves, and they have done an amazingly good job of keeping up to speed. Be, Inc. has to write all their own drivers, though as BeOS has begun gathering momentum, third-party developers have begun to contribute drivers, which are available on Be's web site.

The unspoken alternative is to severely limit the hardware your OS runs on, which for a software company would be a death sentence, but for a hardware company is a no-brainer.

As an aside, people are still wondering: How close did Apple come to buying BeOS, when they were casting around for an OS X foundation?

But Microsoft owns the high ground at the moment, because it doesn't have to write its own drivers. Any hardware maker bringing a new video card or peripheral device to market today knows that it will be unsalable unless it comes with the hardware-specific code that will make it work under Windows, and so each hardware maker has accepted the burden of creating and maintaining its own library of drivers.

MINDSHARE

The U.S. Government's assertion that Microsoft has a monopoly in the OS market might be the most patently absurd claim ever advanced by the legal mind. Linux, a technically superior operating system, is being given away for free, and BeOS is available at a nominal price. This is simply a fact, which has to be accepted whether or not you like Microsoft.

These facts lead one to wonder: How is Microsoft managing to demand money for something that is being given away for free? And demand it in over 90% of the new PC market? Doesn't that position make us even a little suspicious?

Microsoft is really big and rich, and if some of the government's witnesses are to be believed, they are not nice guys. But the accusation of a monopoly simply does not make any sense.

What is really going on is that Microsoft has seized, for the time being, a certain type of high ground: they dominate in the competition for mindshare, and so any hardware or software maker who wants to be taken seriously feels compelled to make a product that is compatible with their operating systems. Since Windows-compatible drivers get written by the hardware makers, Microsoft doesn't have to write them; in effect, the hardware makers are adding new components to Windows, making it a more capable OS, without charging Microsoft for the service. It is a very good position to be in. The only way to fight such an opponent is to have an army of highly competetent coders who write equivalent drivers for free, which Linux does.

This ignores a lot of shifty business practices that Microsoft employed to gain and keep its position. My favorite example is the exclusionary contracts that manufacturers had to submit themselves to, when bundling the OS with their new hardware.

The idea that the free nature of Linux invalidates any monopoly claims aimed at Microsoft is nonsensical. If anything, it magnifies the skewed terrain of the playing field. Linux and Windows run on every home PC spat out by Dell in the 90's. Linux came pre-installed on zero (0%) of those machines, and Windows came pre-installed on all (100%) of those machines. The cost of the Windows OS pre-installed on your Dell machine was actually merged into the price you paid up front, no matter what you eventually did with the hardware, and there was no easy way to separate those two costs. Microsoft got their cut of every machine sold. Does that sound like a phenomenon created by a thriving, dynamic, anything-goes free market to you?

But possession of this psychological high ground is different from a monopoly in any normal sense of that word, because here the dominance has nothing to do with technical performance or price. The old robber-baron monopolies were monopolies because they physically controlled means of production and/or distribution. But in the software business, the means of production is hackers typing code, and the means of distribution is the Internet, and no one is claiming that Microsoft controls those.

Ha ha ha ha ha ha!! See example above. The Internet is not the primary means of distributing operating systems. Downloading an OS is a basic Catch-22: How do you download one, unless you have one already? Internet distribution may be the primary means for a debatable fraction of the software business, but it's a wash for the OS business. In fact, looking at the conduct of Microsoft in the 1990's, Neal's comparison involving robber-barons is shockingly apt.

Here, instead, the dominance is inside the minds of people who buy software. Microsoft has power because people believe it does. This power is very real. It makes lots of money. Judging from recent legal proceedings in both Washingtons, it would appear that this power and this money have inspired some very peculiar executives to come out and work for Microsoft, and that Bill Gates should have administered saliva tests to some of them before issuing them Microsoft ID cards.

But this is not the sort of power that fits any normal definition of the word "monopoly," and it's not amenable to a legal fix. The courts may order Microsoft to do things differently. They might even split the company up. But they can't really do anything about a mindshare monopoly, short of taking every man, woman, and child in the developed world and subjecting them to a lengthy brainwashing procedure.

And putting a murderer in jail will not raise the dead. But it will certainly curtail his future activities. This whole section about mindshare has placed the cart before the horse.

Mindshare dominance is, in other words, a really odd sort of beast, something that the framers of our antitrust laws couldn't possibly have imagined. It looks like one of these modern, wacky chaos-theory phenomena, a complexity thing, in which a whole lot of independent but connected entities (the world's computer users), making decisions on their own, according to a few simple rules of thumb, generate a large phenomenon (total domination of the market by one company) that cannot be made sense of through any kind of rational analysis. Such phenomena are fraught with concealed tipping-points and all a-tangle with bizarre feedback loops, and cannot be understood; people who try, end up (a) going crazy, (b) giving up, (c) forming crackpot theories, or (d) becoming high-paid chaos theory consultants.

Actually it's simple: You get mindshare dominance with good advertising, of any variety. How much money you need to spend in the process is inversely related to the quality, and novelty, of your product. Unfortunately, the Operating System is no longer novel, and of increasingly questionable quality.

Now, there might be one or two people at Microsoft who are dense enough to believe that mindshare dominance is some kind of stable and enduring position. Maybe that even accounts for some of the weirdos they've hired in the pure-business end of the operation, the zealots who keep getting hauled into court by enraged judges. But most of them must have the wit to understand that phenomena like these are maddeningly unstable, and that there's no telling what weird, seemingly inconsequential event might cause the system to shift into a radically different configuration.

Like say, the release of the iPod.

To put it another way, Microsoft can be confident that Thomas Penfield Jackson will not hand down an order that the brains of everyone in the developed world are to be summarily re-programmed. But there's no way to predict when people will decide, en masse, to re-program their own brains. This might explain some of Microsoft's behavior, such as their policy of keeping eerily large reserves of cash sitting around, and the extreme anxiety that they display whenever something like Java comes along.

I have never seen the inside of the building at Microsoft where the top executives hang out, but I have this fantasy that in the hallways, at regular intervals, big red alarm boxes are bolted to the wall. Each contains a large red button protected by a windowpane. A metal hammer dangles on a chain next to it. Above is a big sign reading: IN THE EVENT OF A CRASH IN MARKET SHARE, BREAK GLASS.

What happens when someone shatters the glass and hits the button, I don't know, but it sure would be interesting to find out. One imagines banks collapsing all over the world as Microsoft withdraws its cash reserves, and shrink-wrapped pallet-loads of hundred-dollar bills dropping from the skies. No doubt, Microsoft has a plan. But what I would really like to know is whether, at some level, their programmers might heave a big sigh of relief if the burden of writing the One Universal Interface to Everything were suddenly lifted from their shoulders.

THE RIGHT PINKY OF GOD

I'm not going to touch this section, except to refer the interested reader to additional reading material on the formation of the universe.

For example, determining the initial wrinkles of space-time by listening to the "overtones" of the Big Bang.

In his book The Life of the Cosmos, which everyone should read, Lee Smolin gives the best description I've ever read of how our universe emerged from an uncannily precise balancing of different fundamental constants. The mass of the proton, the strength of gravity, the range of the weak nuclear force, and a few dozen other fundamental constants completely determine what sort of universe will emerge from a Big Bang. If these values had been even slightly different, the universe would have been a vast ocean of tepid gas or a hot knot of plasma or some other basically uninteresting thing--a dud, in other words. The only way to get a universe that's not a dud--that has stars, heavy elements, planets, and life--is to get the basic numbers just right. If there were some machine, somewhere, that could spit out universes with randomly chosen values for their fundamental constants, then for every universe like ours it would produce 10^229 duds.

Though I haven't sat down and run the numbers on it, to me this seems comparable to the probability of making a Unix computer do something useful by logging into a tty and typing in command lines when you have forgotten all of the little options and keywords. Every time your right pinky slams that ENTER key, you are making another try. In some cases the operating system does nothing. In other cases it wipes out all of your files. In most cases it just gives you an error message. In other words, you get many duds. But sometimes, if you have it all just right, the computer grinds away for a while and then produces something like emacs. It actually generates complexity, which is Smolin's criterion for interestingness.

Not only that, but it's beginning to look as if, once you get below a certain size--way below the level of quarks, down into the realm of string theory--the universe can't be described very well by physics as it has been practiced since the days of Newton. If you look at a small enough scale, you see processes that look almost computational in nature.

I think that the message is very clear here: somewhere outside of and beyond our universe is an operating system, coded up over incalculable spans of time by some kind of hacker-demiurge. The cosmic operating system uses a command-line interface. It runs on something like a teletype, with lots of noise and heat; punched-out bits flutter down into its hopper like drifting stars. The demiurge sits at his teletype, pounding out one command line after another, specifying the values of fundamental constants of physics:

universe -G 6.672e-11 -e 1.602e-19 -h 6.626e-34 -protonmass 1.673e-27....

and when he's finished typing out the command line, his right pinky hesitates above the ENTER key for an aeon or two, wondering what's going to happen; then down it comes--and the WHACK you hear is another Big Bang.

Now THAT is a cool operating system, and if such a thing were actually made available on the Internet (for free, of course) every hacker in the world would download it right away and then stay up all night long messing with it, spitting out universes right and left. Most of them would be pretty dull universes but some of them would be simply amazing. Because what those hackers would be aiming for would be much more ambitious than a universe that had a few stars and galaxies in it. Any run-of-the-mill hacker would be able to do that. No, the way to gain a towering reputation on the Internet would be to get so good at tweaking your command line that your universes would spontaneously develop life. And once the way to do that became common knowledge, those hackers would move on, trying to make their universes develop the right kind of life, trying to find the one change in the Nth decimal place of some physical constant that would give us an Earth in which, say, Hitler had been accepted into art school after all, and had ended up his days as a street artist with cranky political opinions.

Even if that fantasy came true, though, most users (including myself, on certain days) wouldn't want to bother learning to use all of those arcane commands, and struggling with all of the failures; a few dud universes can really clutter up your basement. After we'd spent a while pounding out command lines and hitting that ENTER key and spawning dull, failed universes, we would start to long for an OS that would go all the way to the opposite extreme: an OS that had the power to do everything--to live our life for us. In this OS, all of the possible decisions we could ever want to make would have been anticipated by clever programmers, and condensed into a series of dialog boxes. By clicking on radio buttons we could choose from among mutually exclusive choices (HETEROSEXUAL/HOMOSEXUAL). Columns of check boxes would enable us to select the things that we wanted in our life (GET MARRIED/WRITE GREAT AMERICAN NOVEL) and for more complicated options we could fill in little text boxes (NUMBER OF DAUGHTERS: NUMBER OF SONS:).

Even this user interface would begin to look awfully complicated after a while, with so many choices, and so many hidden interactions between choices. It could become damn near unmanageable--the blinking twelve problem all over again. The people who brought us this operating system would have to provide templates and wizards, giving us a few default lives that we could use as starting places for designing our own. Chances are that these default lives would actually look pretty damn good to most people, good enough, anyway, that they'd be reluctant to tear them open and mess around with them for fear of making them worse. So after a few releases the software would begin to look even simpler: you would boot it up and it would present you with a dialog box with a single large button in the middle labeled: LIVE. Once you had clicked that button, your life would begin. If anything got out of whack, or failed to meet your expectations, you could complain about it to Microsoft's Customer Support Department. If you got a flack on the line, he or she would tell you that your life was actually fine, that there was not a thing wrong with it, and in any event it would be a lot better after the next upgrade was rolled out. But if you persisted, and identified yourself as Advanced, you might get through to an actual engineer.

What would the engineer say, after you had explained your problem, and enumerated all of the dissatisfactions in your life? He would probably tell you that life is a very hard and complicated thing; that no interface can change that; that anyone who believes otherwise is a sucker; and that if you don't like having choices made for you, you should start making your own.

Only computer hackers who have delved into the inconvenient guts of an operating system that turns their home computer into a giant pile of tinker-toys are truly liberated from the cruel manipulation of their slipshod corporate taskmasters. You know what I think makes an operating system truly great? Its ability to help me GET MY WORK DONE.

I, too, adventured in the realm of zoomy CPU-meter lights, hacker techno-geek chic, machine-language softswitch twiddling, fuzzy grayscale GIFs of porn stars, and spent endless caffeinated hours diagnosing IRQ and baudrate settings so I could play Duke Nukem with my friend Brent. Then something wonderful happened: I got tired of computing for it's own sake, and started seeking software and hardware that was not an end unto itself, but an efficient means to complete a task.

So I bought a Powerbook with OS X on it. And while an excellent solution, this is certainly not the only solution. A Windows 2000 setup on a Dell Inspiron laptop would be a fine second choice. And though there are many out there who have developed a comfortable Linux system for themselves, I believe that we should all be judged by the truest measure of the value of any personal computer: How much does it help us accomplish our tasks?
