Free for All by Peter Wayner (great books to read .txt) 📖

steal the ideas the source spelled out. The source code, which is written in languages like C, Java, FORTRAN, BASIC, or Pascal, is meant to be read by programmers. Most companies didn't want other programmers understanding too much about the guts of their software. Information is power, and the companies instinctively played their cards close to their chests.

When Linus Torvalds first started writing Linux in 1991, however, he decided to give away the operating system for free. He included all the source code because he wanted others to read it, comment upon it, and perhaps improve it. His decision was as much a radical break from standard programming procedure as a practical decision. He was a poor student at the time, and this operating system was merely a hobby. If he had tried to sell it, he wouldn't have gotten anything for it. He certainly had no money to build a company that could polish the software and market it. So he just sent out copies over the Internet.

Sharing software had already been endorsed by Richard Stallman, a legendary programmer from MIT who believed that keeping source code private was a sin and a crime against humanity. A programmer who shares the source code lets others learn, and those others can contribute their ideas back into the mix. Closed source code leaves users frustrated because they can't learn about the software or fix any bugs. Stallman broke away from MIT in 1984 when he founded the Free Software Foundation. This became the organization that sponsored Stallman's grand project to free source code, a project he called GNU. In the 1980s, Stallman created very advanced tools like the GNU Emacs text editor, which people could use to write programs and articles. Others donated their work and the GNU project soon included a wide range of tools, utilities, and games. All of them were distributed for free.

Torvalds looked at Stallman and decided to follow his lead with open source code. Torvalds's free software began to attract people who liked to play around with technology. Some just glanced at it. Others messed around for a few hours. Free is a powerful incentive. It doesn't let money, credit cards, purchase orders, and the boss's approval get in the way of curiosity. A few, like Alan Cox, had such a good time taking apart an operating system that they stayed on and began contributing back to the project.

In time, more and more people like Alan Cox discovered Torvalds's little project on the Net. Some slept late. Others kept normal hours and worked in offices. Some just found bugs. Others fixed the bugs. Still others added new features that they wanted. Slowly, the operating system grew from a toy that satisfied the curiosity of computer scientists into a usable tool that powers supercomputers, web servers, and millions of other machines around the world.

Today, about a thousand people regularly work with people like Alan Cox on the development of the Linux kernel, the official name for the part of the operating system that Torvalds started writing back in 1991. That may not be an accurate estimate because many people check in for a few weeks when a project requires their participation. Some follow everything, but most people are just interested in little corners. Many other programmers have contributed various pieces of software such as word processors or spreadsheets. All of these are bundled together into packages that are often called plain Linux or GNU/Linux and shipped by companies like Red Hat or more ad hoc groups like Debian.[^1] While Torvalds only wrote the core kernel, people use his name, Linux, to stand for a whole body of software written by thousands of others. It's not exactly fair, but most let it slide. If there hadn't been the Linux kernel, the users wouldn't have the ability to run software on a completely free system. The free software would need to interact with something from Microsoft, Apple, or IBM. Of course, if it weren't for all of the other free software from Berkeley, the GNU project, and thousands of other garages around the world, there would be little for the Linux kernel to do.

Officially, Linus Torvalds is the final arbiter for the kernel and the one who makes the final decisions about new features. In practice, the group runs like a loosely knit "ad-hocracy." Some people might care about a particular feature like the ability to interface with Macintoshes, and they write special code that makes this task easier. Others who run really big databases may want larger file systems that can store more information without limits.

All of these people work at their own pace. Some work in their homes, like Alan Cox. Some work in university labs. Others work for businesses that use Linux and encourage their programmers to plug away so it serves their needs.

The team is united by mailing lists. The Linux Kernel mailing list hooks up Cox in Britain, Torvalds in Silicon Valley, and the others around the globe. They post notes to the list and discuss ideas. Sometimes verbal fights break out, and sometimes everyone agrees. Sometimes people light a candle by actually writing new code to make the kernel better, and other times they just curse the darkness.

Cox is now one of several people responsible for coordinating the addition of new code. He tests it for compatibility and guides Linux authors to make sure they're working together optimally. In essence, he tests every piece of incoming software to make sure all of the gauges work with the right system of measurement so there will be no glitches. He tries to remove the incompatibilities that marred Zorro.

Often, others will duplicate Cox's work. Some new features are very popular and have many cooks minding the stew. The technology for speeding up computers with multiple CPUs lets each computer harness the extra power, so many list members test it frequently. They want the fastest machines they can get, and smoothing the flow of data between the CPUs is the best way to let the machines cooperate.

Other features are not so popular, and they're tackled by the people who need the features. Some people want to hook their Linux boxes up to Macintoshes. Doing that smoothly can require some work in the kernel. Others may want to add special code to enable a special device like a high-speed camera or a strange type of disk drive. These groups often work on their own but coordinate their solutions with the main crowd. Ideally, they'll be able to come up with some patches that solve their problem without breaking some other part of the system.

It's a very social and political process that unrolls in slow motion through e-mail messages. One person makes a suggestion. Others may agree. Someone may squabble with the idea because it seems inelegant, sloppy, or, worst of all, dangerous. After some time, a rough consensus evolves. Easy problems can be solved in days or even minutes, but complicated decisions can wait as the debate rages for years.

Each day, Cox and his virtual colleagues pore through the lists trying to figure out how to make Linux better, faster, and more usable. Sometimes they skip out to watch a movie. Sometimes they go for hikes. But one thing they don't do is spend months huddled in conference rooms trying to come up with legal arguments. Until recently, the Linux folks didn't have money for lawyers, and that means they didn't get sidetracked by figuring out how to get big and powerful people like Richard Schmalensee to tell a court that there's no monopoly in the computer operating system business.

3.2 SUITS AGAINST HACKERS

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

Schmalensee and Cox couldn't be more different from each other. One is a career technocrat who moves easily between the government and MIT. The other is what used to be known as an absentminded professor--the kind who works when he's really interested in a problem. It just so happens that Cox is pretty intrigued with building a better operating system than the various editions of Windows that form the basis of Microsoft's domination of the computer industry.

The battle between Linux and Microsoft is lining up to be the classic fight between the people like Schmalensee and the people like Cox. On one side are the armies of lawyers, lobbyists, salesmen, and expensive executives who are armed with patents, lawsuits, and legislation. They are skilled at moving the levers of power until the gears line up just right and billions of dollars pour into their pockets. They know how to schmooze, toady, beg, or even threaten until they wear the mantle of authority and command the piety and devotion of the world. People buy Microsoft because it's "the standard." No one decreed this, but somehow it has come to be.

On the other side are a bunch of guys who just like playing with computers and will do anything to take them apart. They're not like the guy in the song by John Mellencamp who sings "I fight authority and authority always wins." Some might have an attitude, but most just want to look at the insides of their computers and rearrange them to hook up to coffee machines or networks. They want to fidget with the guts of their machines. If they weld some spaghetti to the insides, so be it.

Normally, these battles between the suits and the geeks don't threaten the established order. There are university students around the world building solar-powered cars, but they don't actually pose a threat to the oil or auto industries. "21," a restaurant in New York, makes a great hamburger, but they're not going to put McDonald's out of business. The experimentalists and the perfectionists don't usually knock heads with the corporations who depend upon world domination for their profits. Except when it comes to software.

Software is different from cars or hamburgers. Once someone writes the source code, copying the source costs next to nothing. That makes it much easier for tinkerers like Cox to have a global effect. If Cox, Stallman, Torvalds, and his chums just happen to luck upon something that's better than Microsoft, then the rest of the world can share their invention for next to nothing. That's what makes Cox, Torvalds, and their buddies a credible threat no matter how often they sleep late.

It's easy to get high off of the idea alone. A few guys sleeping late and working in bedrooms aren't supposed to catch up to a cash engine like Microsoft. They aren't supposed to create a webserving engine that controls more than half of the web. They aren't supposed to create a graphical user interface for drawing windows and icons on the screen that's much better than Windows. They aren't supposed to
