Free as in Freedom - Sam Williams (read this if .TXT) 📗

A student at the nearby University of Helsinki at the time, Torvalds regarded Stallman with bemusement. “I saw, for the first time in my life, the stereotypical long-haired, bearded hacker type,” recalls Torvalds in his 2001 autobiography Just for Fun. “We don’t have much of them in Helsinki.“See Linus Torvalds and David Diamond, Just For Fun: The

Story of an Accidentaly Revolutionary (HarperCollins Publishers, Inc., 2001): 58-59.

While not exactly attuned to the “sociopolitical” side of the Stallman agenda, Torvalds nevertheless appreciated the agenda’s underlying logic: no programmer writes error-free code. By sharing software, hackers put a program’s improvement ahead of individual motivations such as greed or ego protection.

Like many programmers of his generation, Torvalds had cut his teeth not on mainframe computers like the IBM

7094, but on a motley assortment of home-built computer systems. As university student, Torvalds had made the step up from C programming to Unix, using the university’s MicroVAX. This ladder-like progression had given Torvalds a different perspective on the barriers to machine access. For Stallman, the chief barriers were bureaucracy and privilege. For Torvalds, the chief barriers were geography and the harsh Helsinki winter.

Forced to trek across the University of Helsinki just to log in to his Unix account, Torvalds quickly began looking for a way to log in from the warm confines of his off-campus apartment.

The search led Torvalds to the operating system Minix, a lightweight version of Unix developed for instructional purposes by Dutch university professor Andrew Tanenbaum. The program fit within the memory confines of a 386 PC, the most powerful machine Torvalds could afford, but still lacked a few necessary features. It most notably lacked terminal emulation, the feature that allowed Torvalds’ machine to mimic a university terminal, making it possible to log in to the MicroVAX from home.

During the summer of 1991, Torvalds rewrote Minix from the ground up, adding other features as he did so. By the end of the summer, Torvalds was referring to his evolving work as the “GNU/Emacs of terminal emulation programs.“See Linus Torvalds and David Diamond, Just For Fun: The Story of an Accidentaly Revolutionary (HarperCollins Publishers, Inc., 2001): 78.

Feeling confident, he solicited a Minix newsgroup for copies of the POSIX standards, the software blue prints that determined whether a program was Unix compatible.

A few weeks later, Torvalds was posting a message eerily reminiscent of Stallman’s original 1983 GNU posting: Hello everybody out there using minix-I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu for 386 (486) AT

clones). This has been brewing since April, and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).See “Linux 10th Anniversary.”

The posting drew a smattering of responses and within a month, Torvalds had posted a 0.01 version of the operating system-i.e., the earliest possible version fit for outside review-on an Internet FTP site. In the course of doing so, Torvalds had to come up with a name for the new system. On his own PC hard drive, Torvalds had saved the program as Linux, a name that paid its respects to the software convention of giving each Unix variant a name that ended with the letter X. Deeming the name too “egotistical,” Torvalds changed it to Freax, only to have the FTP site manager change it back.

Although Torvalds had set out build a full operating system, both he and other developers knew at the time that most of the functional tools needed to do so were already available, thanks to the work of GNU, BSD, and other free software developers. One of the first tools the Linux development team took advantage of was the GNU C Compiler, a tool that made it possible to process programs written in the C programming language.

Integrating GCC improved the performance of Linux. It also raised issues. Although the GPL’s “viral” powers didn’t apply to the Linux kernel, Torvald’s willingness to borrow GCC for the purposes of his own free software operating system indicated a certain obligation to let other users borrow back. As Torvalds would later put it: “I had hoisted myself up on the shoulders of giants.“See Linus Torvalds and David Diamond, Just For Fun: The

Story of an Accidentaly Revolutionary (HarperCollins Publishers, Inc., 2001): 96-97.

Not surprisingly, he began to think about what would happen when other people looked to him for similar support. A decade after the decision, Torvalds echoes the Free Software Foundation’s Robert Chassel when he sums up his thoughts at the time: You put six months of your life into this thing and you want to make it available and you want to get something out of it, but you don’t want people to take advantage of it. I wanted people to be able to see [Linux], and to make changes and improvements to their hearts’ content. But I also wanted to make sure that what I got out of it was to see what they were doing. I wanted to always have access to the sources so that if they made improvements, I could make those improvements myself.See Linus Torvalds and David Diamond, Just For Fun: The

Story of an Accidentaly Revolutionary (HarperCollins Publishers, Inc., 2001): 94-95.

When it was time to release the 0.12 version of Linux, the first to include a fully integrated version of GCC, Torvalds decided to voice his allegiance with the free software movement. He discarded the old kernel license and replaced it with the GPL. The decision triggered a porting spree, as Torvalds and his collaborators looked to other GNU programs to fold into the growing Linux stew. Within three years, Linux developers were offering their first production release, Linux 1.0, including fully modified versions of GCC, GDB, and a host of BSD tools.

By 1994, the amalgamated operating system had earned enough respect in the hacker world to make some observers wonder if Torvalds hadn’t given away the farm by switching to the GPL in the project’s initial months. In the first issue of Linux Journal, publisher Robert Young sat down with Torvalds for an interview.

When Young asked the Finnish programmer if he felt regret at giving up private ownership of the Linux source code, Torvalds said no. “Even with 20/20

hindsight,” Torvalds said, he considered the GPL “one of the very best design decisions” made during the early stages of the Linux project.See Robert Young, “Interview with Linus, the Author of

Linux,” Linux Journal (March 1, 1994).

That the decision had been made with zero appeal or deference to Stallman and the Free Software Foundation speaks to the GPL’s growing portability. Although it would take a few years to be recognized by Stallman, the explosiveness of Linux development conjured flashbacks of Emacs. This time around, however, the innovation triggering the explosion wasn’t a software hack like Control-R but the novelty of running a Unix-like system on the PC architecture. The motives may have been different, but the end result certainly fit the ethical specifications: a fully functional operating system composed entirely of free software.

As his initial email message to the comp.os.minix newsgroup indicates, it would take a few months before Torvalds saw Linux as anything less than a holdover until the GNU developers delivered on the HURD kernel.

This initial unwillingness to see Linux in political terms would represent a major blow to the Free Software Foundation.

As far as Torvalds was concerned, he was simply the latest in a long line of kids taking apart and reassembling things just for fun. Nevertheless, when summing up the runaway success of a project that could have just as easily spent the rest of its days on an abandoned computer hard drive, Torvalds credits his younger self for having the wisdom to give up control and accept the GPL bargain.

“I may not have seen the light,” writes Torvalds, reflecting on Stallman’s 1991 Polytechnic University speech and his subsequent decision to switch to the GPL. “But I guess something from his speech sunk in .“See Linus Torvalds and David Diamond, Just For Fun: The

Story of an Accidentaly Revolutionary (HarperCollins Publishers, Inc., 2001): 59.

interview offers an interesting, not to mention candid, glimpse at Stallman’s political attitudes during the earliest days of the GNU Project. It is also helpful in tracing the evolution of Stallman’s rhetoric. Describing the purpose of the GPL, Stallman says, “I’m trying to change the way people approach knowledge and information in general. I think that to try to own knowledge, to try to control whether people are allowed to use it, or to try to stop other people from sharing it, is sabotage.” Contrast this with a statement to the author in August 2000: “I urge you not to use the term `intellectual property’ in your thinking. It will lead you to misunderstand things, because that term generalizes about copyrights, patents, and trademarks. And those things are so different in their effects that it is entirely foolish to try to talk about them at once. If you hear somebody saying something about intellectual property, without quotes, then he’s not thinking very clearly and you shouldn’t join.”

GNU/Linux

By 1993, the free software movement was at a crossroads. To the optimistically inclined, all signs pointed toward success for the hacker cultur. Wired magazine, a funky, new publication offering stories on data encryption, Usenet, and software freedom, was flying off magazine racks. The Internet, once a slang term used only by hackers and research scientists, had found its way into mainstream lexicon. Even President Clinton was using it. The personal computer, once a hobbyist’s toy, had grown to full-scale respectability, giving a whole new generation of computer users access to hacker-built software. And while the GNU Project had not yet reached its goal of a fully intact, free software operating system, curious users could still try Linux in the interim.

Any way you sliced it, the news was good, or so it seemed. After a decade of struggle, hackers and hacker values were finally gaining acceptance in mainstream society. People were getting it.

Or were they? To the pessimistically inclined, each sign of acceptance carried its own troubling countersign. Sure, being a hacker was suddenly cool, but was cool good for a community that thrived on alienation? Sure, the White House was saying all the right things about the Internet, even going so far as to register its own domain name, whitehouse.gov, but it was also meeting with the companies, censorship advocates, and law-enforcement officials looking to tame the Internet’s Wild West culture. Sure, PCs were more powerful, but in commoditizing the PC marketplace with its chips, Intel had created a situation in which proprietary software vendors now held the power. For every new user won over to the free software cause via Linux, hundreds, perhaps thousands, were booting up Microsoft Windows for the first time.

Finally, there was the curious nature of Linux itself.

Unrestricted by design bugs (like GNU) and legal disputes (like BSD), Linux’ high-speed evolution had been so unplanned, its success so accidental, that programmers closest to the software code itself didn’t know what to make of it. More compilation album than operating system, it was comprised of a hacker medley of greatest hits: everything from GCC, GDB, and glibc (the GNU Project’s newly developed C Library) to X (a Unix-based graphic user interface developed by MIT’s Laboratory for Computer Science) to BSD-developed tools such as BIND (the Berkeley Internet Naming Daemon, which lets users substitute easy-to-remember Internet domain names for numeric IP addresses) and TCP/IP. The arch’s capstone, of course, was the Linux kernel-itself a bored-out, super-charged version of Minix. Rather than building their operating system from scratch, Torvalds and his rapidly expanding Linux development
