and made it possible for someone to run a computer without paying anyone for a license. Richard Stallman had dreamed of this day, and Torvalds came up with the last major piece of the puzzle.

8.2 A DIFFERENT KIND OF TRIAL

.............................

During the early months of Torvalds's work, the BSD group was stuck in a legal swamp. While the BSD team was involved with secret settlement talks and secret depositions, Linus Torvalds was happily writing code and sharing it with the world on the Net. His life wasn't all peaches and cream, but all of his hassles were open. Professor Andy Tanenbaum, a fairly well-respected and famous computer scientist, got in a long, extended debate with Torvalds over the structure of Linux. He looked down at Linux and claimed that Linux would have been worth two F's in his class because of its design. This led to a big flame war that was every bit as nasty as the fight between Berkeley and AT&T's USL. In fact, to the average observer it was even nastier. Torvalds returned Tanenbaum's fire with strong words like "fiasco," "brain-damages," and "suck." He brushed off the bad grades by pointing out that Albert Einstein supposedly got bad grades in math and physics. The highpriced lawyers working for AT&T and Berkeley probably used very expensive and polite words to try and hide the shivs they were trying to stick in each other's back. Torvalds and Tanenbaum pulled out each other's virtual hair like a squawkfest on the Jerry Springer show.

But Torvalds's flame war with Tanenbaum occurred in the open in an Internet newsgroup. Other folks could read it, think about it, add their two cents' worth, and even take sides. It was a wide-open debate that uncovered many flaws in the original versions of Linux and Tanenbaum's Minix. They forced Torvalds to think deeply about what he wanted to do with Linux and consider its flaws. He had to listen to the arguments of a critic and a number of his peers on the Net and then come up with arguments as to why his Linux kernel didn't suck too badly.

This open fight had a very different effect from the one going on in the legal system. Developers and UNIX hackers avoided the various free versions of BSD because of the legal cloud. If a judge decided that AT&T and USL were right, everyone would have to abandon their work on the platform. While the CSRG worked hard to get free, judges don't always make the choices we want.

The fight between Torvalds and Tanenbaum, however, drew people into the project. Other programmers like David Miller, Ted T'so, and Peter da Silva chimed in with their opinions. At the time, they were just interested bystanders. In time, they became part of the Linux brain trust. Soon they were contributing source code that ran on Linux. The argument's excitement forced them to look at Torvalds's toy OS and try to decide whether his defense made any sense. Today, David Miller is one of the biggest contributors to the Linux kernel. Many of the original debaters became major contributors to the foundations of Linux.

This fight drew folks in and kept them involved. It showed that Torvalds was serious about the project and willing to think about its limitations. More important, it exposed these limitations and inspired other folks on the Net to step forward and try to fix them. Everyone could read the arguments and jump in. Even now, you can dig up the archives of this battle and read in excruciating detail what people were thinking and doing. The AT&T/USL-versus-Berkeley fight is still sealed.

To this day, all of the devotees of the various BSDs grit their teeth when they hear about Linux. They think that FreeBSD, NetBSD, and OpenBSD are better, and they have good reasons for these beliefs. They know they were out the door first with a complete running system. But Linux is on the cover of the magazines. All of the great technically unwashed are now starting to use "Linux" as a synonym for free software. If AT&T never sued, the BSD teams would be the ones reaping the glory. They would be the ones to whom Microsoft turned when it needed a plausible competitor. They would be more famous.

But that's crying over spilled milk. The Berkeley CSRG lived a life of relative luxury in their world made fat with big corporate and government donations. They took the cash, and it was only a matter of time before someone called them on it. Yes, they won in the end, but it came too late. Torvalds was already out of the gate and attracting more disciples.

McKusick says, "If you plot the installation base of Linux and BSD over the last five years, you'll see that they're both in exponential growth. But BSD's about eighteen to twenty months behind. That's about how long it took between Net Release 2 and the unencumbered 4.4BSD-Lite. That's about how long it took for the court system to do its job."

GROWTH

Through the 1990s, the little toy operating system grew slowly and quietly as more and more programmers were drawn into the vortex. At the beginning, the OS wasn't rich with features. You could run several different programs at once, but you couldn't do much with the programs. The system's interface was just text. Still, this was often good enough for a few folks in labs around the world. Some just enjoyed playing with computers. Getting Linux running on their PC was a challenge, not unlike bolting an aftermarket supercharger onto a Honda Civic. But others took the project more seriously because they had serious jobs that couldn't be solved with a proprietary operating system that came from Microsoft or others.

In time, more people started using the system and started contributing their additions to the pot. Someone figured out how to make MIT's free X Window System run on Linux so everyone could have a graphical interface. Someone else discovered how to roll in technology for interfacing with the Internet. That made a big difference because everyone could hack, tweak, and fiddle with the code and then just upload the new versions to the Net.

It goes without saying that all the cool software coming out of Stallman's Free Software Foundation found its way to Linux. Some were simple toys like GNU Chess, but others were serious tools that were essential to the growth of the project. By 1991, the FSF was offering what might be argued were the best text editor and compiler in the world. Others might have been close, but Stallman's were free. These were crucial tools that made it possible for Linux to grow quickly from a tiny experimental kernel into a full-featured OS for doing everything a programmer might want to do.

James Lewis-Moss, one of the many programmers who devote some time to Linux, says that GCC made it possible for programmers to create, revise, and extend the kernel. "GCC is integral to the success of Linux," he says, and points out that this may be one of the most important reasons why "it's polite to refer to it as GNU/Linux."

Lewis-Moss points out one of the smoldering controversies in the world of free software: all of the tools and games that came from the GNU project started becoming part of what people simply thought of as plain "Linux." The name for the small kernel of the operating system soon grew to apply to almost all the free software that ran with it. This angered Stallman, who first argued that a better name would be"Lignux."When that failed to take hold, he moved to "GNU/Linux." Some ignored his pleas and simply used "Linux," which is still a bit unfair. Some feel that"GNU/Linux"is too much of a mouthful and, for better or worse, just plain Linux is an appropriate shortcut. Some, like Lewis-Moss, hold firm to GNU/Linux.

Soon some people were bundling together CD-ROMs with all this software in one batch. The group would try to work out as many glitches as possible so that the purchaser's life would be easier. All boasted strange names like Yggdrasil, Slackware, SuSE, Debian, or Red Hat. Many were just garage projects that never made much money, but that was okay. Making money wasn't really the point. People just wanted to play with the source. Plus, few thought that much money could be made. The GPL, for instance, made it difficult to differentiate the product because it required everyone to share their source code with the world. If Slackware came up with a neat fix that made their version of Linux better, then Debian and SuSE could grab it. The GPL prevented anyone from constraining the growth of Linux.

But only greedy businessmen see sharing and competition as negatives. In practice, the free flow of information enhanced the market for Linux by ensuring that it was stable and freely available. If one key CDROM developer gets a new girlfriend and stops spending enough time programming, another distribution will pick up the slack. If a hurricane flattened Raleigh, North Carolina, the home of Red Hat, then another supplier would still be around. A proprietary OS like Windows is like a set of manacles. An earthquake in Redmond, Washington, could cause a serious disruption for everyone.

The competition and the GPL meant that the users would never feel bound to one OS. If problems arose, anyone could always just start a splinter group and take Linux in that direction. And they did. All the major systems began as splinter groups, and some picked up enough steam and energy to dominate. In time, the best splinter groups spun off their own splinter groups and the process grew terribly complicated.

9.1 THE ESTABLISHMENT BEGINS TO NOTICE

......................................

By the mid-1990s, the operating system had already developed quite a following. In 1994, Jon Hall was a programmer for Digital, a company that was later bought by Compaq. Hall also wears a full beard and uses the name "maddog" as a nickname. At that time, Digital made workstations that ran a version of UNIX. In the early 1990s, Digital made a big leap forward by creating a 64-bit processor version of its workstation CPU chip, the Alpha, and the company wanted to make sure that the chip found widespread acceptance.

Hall remembers well the moment he discovered Linux. He told Linux Today,

I didn't even know I was involved with Linux at first. I got a copy of Dr. Dobb's Journal, and in there was an advertisement for "get a UNIX operating system, all the source code, and run it on your PC." And I think it was $99. And I go, "Oh, wow, that's pretty cool. For $99, I can do that." So I sent away for it, got the CD. The only trouble was that I didn't have a PC to run it on. So I put it on my Ultrix system, took a look at the main pages, directory structure and stuff, and said, "Hey, that looks pretty cool." Then I put it away in the filing cabinet. That was probably around January of 1994.

In May 1994, Hall met Torvalds at a DECUS (Digital Equipment Corporation User Society) meeting and became a big fan. Hall is a programmer's programmer who has written code for many different machines over the years, like the IBM 1130 and the DEC PDP-8. He started out as an electrical engineer in college, but took up writing software "after seeing a friend of mine fried by 13,600 volts and 400 amps, which was not a pretty sight." Hall started playing with UNIX when he worked at Bell Labs and fell in love with the OS.

At the meeting, Torvalds helped Hall and his boss set up a PC with
