Free for All, Peter Wayner [my miracle luna book free read .TXT] 📗

Sun has a contentious relationship with the free software world. It's far from a free software company like Red Hat, but it has contributed a fair number of lines of software to the open source community. Still, Sun guards its intellectual property rights to some packages fiercely and refuses to distribute the source with an official open source license. Instead, it calls their approach the "community source license" and insists that it's good enough for almost everyone. Users can read the source code, but they can't run off with it and start their own distribution.

Many others from Berkeley followed Joy's path to Sun. John Ousterhout left his position as a professor at Berkeley in 1994 to move to Sun. Ousterhout was known for developing a fairly simple but powerful scripting tool known as TCL/Tk. One part of it, the Tool Control Language (TCL), was a straightforward English-like language that made it pretty easy for people to knit together different modules of code. The user didn't have to be a great programmer to work with the code because the language was designed to be straightforward. There were no complicated data structures or pointers. Everything was a string of ASCII text.

The second part, the Tool kit (Tk), contained a variety of visual widgets that could be used to get input for and output from a program. The simplest ones were buttons, sliders, or menus, but many people wrote complicated ones that served their particular needs.

The TCL/Tk project at Berkeley attracted a great deal of attention from the Net. Ousterhout, like most academics, freely distributed his code and did a good job helping others use the software. He and his students rewrote and extended the code a number of times, and this constant support helped create even more fans. The software scratched an itch for many academics who were smart enough to program the machines in their lab, but burdened by more important jobs like actually doing the research they set out to do. TCL/Tk picked up a wide following because it was easy for people to learn a small amount quickly. Languages like C required a semester or more to master. TCL could be picked up in an afternoon.

Many see the pragmatism of the BSD-style license as a way for the Berkeley hackers to ease their trip into corporate software production. The folks would develop the way-out, unproven ideas using public money before releasing it with the BSD license. Then companies like Sun would start to resell it.

The supporters of the BSD licenses, of course, don't see corporate development as a bad thing. They just see it as a way for people to pay for the extra bells and whistles that a dedicated, market-driven team can add to software.

Ousterhout's decision to move to Sun worried many people because they thought it might lead to a commercialization of the language. Ousterhout answered these with an e-mail message that said TCL/Tk would remain free, but Sun would try to make some money on the project by selling development tools.

"Future enhancements made toTcl andTk by my group at Sun, including the ports to Macs and PCs, will be made freely available to anyone to use for any purpose. My view, and that of the people I report to at Sun, is that it wouldn't work for Sun to try to takeTcl andTk proprietary anyway: someone (probably me, in a new job) would just pick up the last free release and start an independent development path. This would be a terrible thing for everyone since it would result in incompatible versions.

"Of course, Sun does need to make money from the work of my team or else they won't be able to continue to support us. Our current plan is to charge for development tools and interesting extensions and applications. Balancing the public and the profitable will be an ongoing challenge for us, but it is very important both to me and to Sun to keep the support of the existing Tcl community," he wrote.

In some respects, Ousterhout's pragmatism was entirely different from Stallman's. He openly acknowledged the need to make money and also admitted that Sun was leaving TCL/Tk free because it might be practically impossible to make it proprietary. The depth of interest in the community made it likely that a free version would continue to evolve. Stallman would never cut such a deal with a company shipping proprietary software.

In other respects, many of the differences are only at the level of rhetoric. Ousterhout worked on producing a compromise that would leave TCL/Tk free while the sales of development tools paid the bills. Stallman did the same thing when he figured out a way to charge people for CD-ROMs and manuals. Ousterhout's work at Sun was spun off into a company called Scriptics that is surprisingly like many of the other free software vendors. The core of the product, TCL/Tk 8.1 at this time, is governed by a BSD-style license. The source code can be downloaded from the site. The company itself, on the other hand, sells a more enhanced product known as TCLPro.

In many ways, the real opposite to Richard Stallman is not Bill Joy or John Ousterhout, it's Linus Benedict Torvalds. While Stallman, Joy, and Ousterhout are products of the U.S. academic system, Torvalds is very much an outsider who found himself trying to program in Europe without access to a decent OS. While the folks at Berkeley, MIT, and many U.S. universities were able to get access to UNIX thanks to carefully constructed licenses produced by the OS's then-owner, AT&T, students in Finland like Torvalds were frozen out.

"I didn't have many alternatives. I had the commercial alternative [UNIX], which was way too expensive. It was really out of reach for a normal human being, and not only out of reach in a monetary sense, but because years ago commercial UNIX vendors weren't interested in selling to individuals. They were interested in selling to large corporations and banks. So for a normal person, there was no choice," he told VAR Business.

When Linux began to take off, Torvalds moved to Silicon Valley and took a job with the supersecret research firm Transmeta. At Comdex in November 1999, Torvalds announced that Transmeta was working on a low-power computing chip with the nickname "Crusoe."

There are, of course, some conspiracy theories. Transmeta is funded by a number of big investors including Microsoft cofounder Paul Allen. The fact that they chose to employ Torvalds may be part of a plan, some think, to distract him from Linux development. After all, version 2.2 of the kernel took longer than many expected, although it may have been because its goals were too ambitious. When Microsoft needed a coherent threat to offer up to the Department of Justice, Transmeta courteously made Torvalds available to the world. Few seriously believe this theory, but it is constantly whispered as a nervous joke.

12.2 FLAMES

...........

The fights and flamefests of the Internet are legendary, and the open source world is one of the most contentious corners of the Net. People frequently use strong words like "brain dead," "loser," "lame," "gross," and "stoooopid" to describe one another's ideas. If words are the only way to communicate, then the battle for mindshare means that those who wield the best words win.

In fact, most of the best hackers and members of the free source world are also great writers. Spending days, weeks, months, and years of your life communicating by e-mail and newsgroups teaches people how to write well and get to the point quickly. The Internet is very textual, and the hard-core computer programmers have plenty of experience spitting out text. As every programmer knows, you're supposed to send e-mail to the person next to you if you want to schedule lunch. That person might be in the middle of something.

Of course, there's a danger to making a sweeping generalization implying that the free source world is filled with great writers. The fact is that we might not have heard from the not-so-great writers who sit lurking on the Net. While some of the students who led the revolutions of 1968 were quite articulate, many of the tie-dyed masses were also in the picture. You couldn't miss them. On the Internet, the silent person is invisible.

Some argue that the free software world has burgeoned because the silent folks embraced the freely available source code. Anyone could download the source code and play with it without asking permission or spending money. That meant that 13-year-old kids could start using the software without asking their parents for money. SCO Unix and Windows NT cost big bucks.

This freedom also extended to programmers at work. In many companies, the computer managers are doctrinaire and officious. They often quickly develop knee-jerk reactions to technologies and use these stereotypes to make technical decisions. Free software like Linux was frequently rejected out of hand by the gatekeepers, who thought something must be wrong with the software if no one was charging for it. These attitudes couldn't stop the engineers who wanted to experiment with the free software, however, because it had no purchase order that needed approval.

The invisible-man quality is an important part of the free software world. While I've described the bodies and faces of some of the betterknown free source poster boys, it is impossible to say much about many of the others. The community is spread out over the Internet throughout the world. Many people who work closely on projects never meet each other. The physical world with all of its ways of encoding a position in a hierarchy are gone. No one can tell how rich you are by your shoes. The color of your skin doesn't register. It's all about technology and technological ideas.

In fact, there is a certain degree of Emily Dickinson in the world. Just as that soul selected her own society and shut the door on the rest of the world, the free software world frequently splits and resplits into smaller groups. While there is some cross-pollination, many are happy to live in their own corners. OpenBSD, FreeBSD, and NetBSD are more separate countries than partners in crime. They evolve on their own, occasionally stealing ideas and source code to bridge the gap.

Many writers have described some of their problems with making hay of the Silicon Valley world. Screenwriters and television producers often start up projects to tap into the rich texture of nerdlands only to discover that there's nothing that compelling to film. It's just miles and miles of steel-frame buildings holding acres and acres of cubicles. Sure, there are some Ping-Pong tables and pinball machines, but the work is all in the mind. Eyes want physical action, and all of the excitement in a free source world is in the ideas.

But people are people. While there's no easy way to use the old standbys of race or clothes to discriminate, the technical world still develops ways to classify its members and place them in camps. The free software world has its own ways to distinguish between these camps.

The biggest distinction may be between folks who favor the GPL and those who use the BSD-style license to protect their software. This is probably the biggest decision a free software creator must make because it controls whether others will be able to build commercial versions of the software without contributing the new code back to the project.

People who embrace the GPL are more likely to embrace Richard Stallman, or at least less likely to curse him in public. They tend to be iconoclastic and individualistic. GPL projects tend to be more cultish and driven by a weird mixture of personality and ain't-it-cool hysteria.

The people on the side of BSD-style license, on the other hand, seem pragmatic, organized, and focused. There are three major free versions of BSD UNIX
