Free for All - Peter Wayner (the false prince series .txt) 📗

There is a good empirical reason for the faith in the strength of free source. After all, a group of folks who rarely saw each other had assembled a great pile of source code that was kicking Microsoft's butt in some corners of the computer world. Linux servers were common on the Internet and growing more common every day. The desktop was waiting to be conquered. They had done this without stock options, without corporate jets, without secret contracts, and without potentially illegal alliances with computer manufacturers. The success of the software from the GNU and Linux world was really quite impressive.

Of course, myths can be taken too far. Programming computers is hard work and often frustrating. Sharing the source code doesn't make bugs or problems go away--it just makes it a bit easier for someone else to dig into a program to see what's going wrong. The source code may just be a list of instructions written in a programming language that is designed to be readable by humans, but that doesn't mean that it is easy to understand. In fact, most humans won't figure out most source code because programming languages are designed to be understood by other programmers, not the general population.

To make matters worse, programmers themselves have a hard time understanding source code. Computer programs are often quite complicated and it can take days, weeks, and even months to understand what a strange piece of source code is telling a computer to do. Learning what is happening in a program can be a complicated job for even the best programmers, and it is not something that is taken lightly.

While many programmers and members of the open source world are quick to praise the movement, they will also be able to cite problems with the myth of the Source. It isn't that the Source doesn't work, they'll say, it's just that it rarely works anywhere near as well as the hype implies. The blooms are rarely as vigorous and the free markets in improvements are rarely as liquid.

Larry McVoy, an avid programmer, proto-academic, and developer of the BitKeeper toolkit, likes to find fault with the model. It isn't that he doesn't like sharing source code, it's just that he isn't wealthy enough to take on free software projects. "We need to find a way for people to develop free software and pay their mortgages and raise a family," he says.

"If you look closely," he says, "there really isn't a bazaar. At the top it's always a one-person cathedral. It's either Linus, Stallman, or someone else." That is, the myth of a bazaar as a wide-open, free-for-all of competition isn't exactly true. Sure, everyone can download the source code, diddle with it, and make suggestions, but at the end of the day it matters what Torvalds, Stallman, or someone else says. There is always a great architect of Chartres lording it over his domain.

Part of this problem is the success of Raymond's metaphor. He said he just wanted to give the community some tools to understand the success of Linux and reason about it. But his two visions of a cathedral and a bazaar had such a clarity that people concentrated more on dividing the world into cathedrals and bazaars. In reality, there's a great deal of blending in between. The most efficient bazaars today are the suburban malls that have one management company building the site, leasing the stores, and creating a unified experience. Downtown shopping areas often failed because there was always one shop owner who could ruin an entire block by putting in a store that sold pornography. On the other side, religion has always been something of a bazaar. Martin Luther effectively split apart Christianity by introducing competition. Even within denominations, different parishes fight for the hearts and souls of people.

The same blurring holds true for the world of open source software. The Linux kernel, for instance, contains many thousands of lines of source code. Some put the number at 500,000. A few talented folks like Alan Cox or Linus Torvalds know all of it, but most are only familiar with the corners of it that they need to know. These folks, who may number in the thousands, are far outnumbered by the millions who use the Linux OS daily.

It's interesting to wonder if the ratio of technically anointed to blithe users in the free source world is comparable to the ratio in Microsoft's dominion. After all, Microsoft will share its source code with close partners after they sign some non-disclosure forms.[^9] While Microsoft is careful about what it tells its partners, it will reveal information only when there's something to gain. Other companies have already jumped right in and started offering source code to all users who want to look at it.

[9]: At this writing, Microsoft has not released its source code, but the company is widely known to be examining the option as part of its settlement with the Department of Justice.

Answering this question is impossible for two different reasons. First, no one knows what Microsoft reveals to its partners because it keeps all of this information secret, by reflex. Contracts are usually negotiated under non-disclosure, and the company has not been shy about exploiting the power that comes from the lack of information.

Second, no one really knows who reads the Linux source code for the opposite reason. The GNU/Linux source is widely available and frequently downloaded, but that doesn't mean it's read or studied. The Red Hat CDs come with one CD full of pre-compiled binaries and the second full of source code. Who knows whoever pops the second CDROM in their computer? Everyone is free to do so in the privacy of their own cubicle, so no records are kept.

If I were to bet, I would guess that the ratios of cognoscenti to uninformed users in the Linux and Microsoft worlds are pretty close. Reading the Source just takes too much time and too much effort for many in the Linux world to take advantage of the huge river of information available to them.

If this is true or at least close to true, then why has the free source world been able to move so much more quickly than the Microsoft world? The answer isn't that everyone in the free source world is using the Source, it's that everyone is free to use it. When one person needs to ask a question or scratch an itch, the Source is available with no questions asked and no lawyers consulted. Even at 3:00 A.M., a person can read the Source. At Microsoft and other corporations, they often need to wait for the person running that division or section to give them permission to access the source code.

There are other advantages. The free source world spends a large amount of time keeping the source code clean and accessible. A programmer who tries to get away with sloppy workmanship and bad documentation will pay for it later as others come along and ask thousands of questions.

Corporate developers, on the other hand, have layers of secrecy and bureaucracy to isolate them from questions and comments. It is often hard to find the right programmer in the rabbit warren of cubicles who has the source code in the first place. One Microsoft programmer was quoted as saying, "A developer at Microsoft working on the OS can't scratch an itch he's got with Excel, neither can the Excel developer scratch his itch with the OS--it would take him months to figure out how to build and debug and install, and he probably couldn't get proper source access anyway."

This problem is endemic to corporations. The customers are buying the binary version, not the source code, so there is no reason to dress up the backstage wings of the theater. After some time, though, people change cubicles, move to other corporations, and information disappears. While companies try to keep source code databases to synchronize development, the efforts often fall apart. After Apple canceled development of their Newton handheld, many Newton users were livid. They had based big projects on the platform and they didn't want to restart their work. Many asked whether Apple could simply give away the OS's source code instead of leaving it to rot on some hard disk. Apple dodged these requests, and this made some people even more cynical. One outside developer speculated, "It probably would not be possible to re-create the OS. The developers are all gone. All of them went to Palm, and they probably couldn't just put it back together again if they wanted to."

Of course, corporations try to fight this rot by getting their programmers to do a good job at the beginning and write plenty of documentation. In practice, this slips a bit because it is not rewarded by the culture of secrecy. I know one programmer who worked for a project at MIT. The boss thought he was being clever by requiring comments on each procedure and actually enforcing it with an automated text-scanning robot that would look over the source code and count the comments. My friend turned around and hooked up one version of the popular artificial intelligence chatterbots like Eliza and funneled the responses into the comment field. Then everyone was happy. The chatterbot filled the comment field, the automated comment police found something vaguely intelligent, and the programmer got to spend his free time doing other things. The boss never discovered the problem.

Programmers are the same the world over, and joining the free source world doesn't make them better people or destroy their impudence. But it does penalize them if others come along and try to use their code. If it's inscrutable, sloppy, or hard to understand, then others will either ignore it or pummel them with questions. That is a strong incentive to do it right.

11.4 OPEN SOURCE AND LIGHTBULBS

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

The limitations to the power of open source might be summarized in the answer to the question "How many open source developers does it take to change a lightbulb?" The answer is: 17. Seventeen to argue about the license; 17 to argue about the brain-deadedness of the lightbulb architecture; 17 to argue about a new model that encompasses all models of illumination and makes it simple to replace candles, campfires, pilot lights, and skylights with the same easy-to-extend mechanism; 17 to speculate about the secretive industrial conspiracy that ensures that lightbulbs will burn out frequently; 1 to finally change the bulb; and 16 who decide that this solution is good enough for the time being.

The open source development model is a great way for very creative people to produce fascinating software that breaks paradigms and establishes new standards for excellence. It may not be the best way, however, to finish boring jobs like fine-tuning a graphical interface, or making sure that the scheduling software used by executives is as bulletproof as possible.

While the open development model has successfully tackled the problem of creating some great tools, of building a strong OS, and of building very flexible appliance applications like web browsers, it is a long way from winning the battle for the desktop. Some free source people say the desktop applications for average users are just around the corner and the next stop on the Free Software Express. Others aren't so sure.

David Henkel-Wallace is one of the founders of the free software company Cygnus. This company built its success around supporting the development tools created by Stallman's Free Software Foundation. They would sign contracts with companies to answer any questions they had about using the free software tools. At first companies would balk at paying for support until they realized that it was cheaper than hiring in-house technical staff to do the work. John Gilmore, one of the cofounders, liked to say, "We make free
