Avenue [in Palo Alto]. We didn't have a garage, we had a carport. It was an apartment complex. We got another apartment and etherneted them together. By the time we left, we had six apartments."

While the Bay Area was very technically sophisticated, the Internet was mainly used at that time by universities and research labs. Commercial hookups were rare and only found in special corners like the corporate research playpen, Xerox PARC. In order to get Net service, Cygnus came up with a novel plan to wire the apartment complex and sell off some of the extra bandwidth to their neighbors. HenkelWallace says, "We started our own ISP [Internet Service Provider] as a cooperative because there weren't those things in those days. Then people moved into those apartments because they were on the Internet."

At the beginning, the company hoped that the free software would allow them to offer something the major manufacturers didn't: cross-platform consistency. The GNU software would perform the same on a DEC Alpha, a Sun SPARC, and even a Microsoft box. The manufacturers, on the other hand, were locked up in their proprietary worlds where there was little cross-pollination. Each company developed its own editors, compilers, and source code tools, and each took slightly different approaches.

One of the other founders, Michael Tiemann, writes of the time: "When it came to tools for programmers in 1989, proprietary software was in a dismal state. First, the tools were primitive in the features they offered. Second, the features, when available, often had built-in limitations that tended to break when projects started to get complicated. Third, support from proprietary vendors was terrible. .. finally, every vendor implemented their own proprietary extensions, so that when you did use the meager features of one platform, you became, imperceptibly at first, then more obviously later, inextricably tied to that platform."

The solution was to clean up the GNU tools, add some features, and sell the package to people who had shops filled with different machines. Henkel-Wallace said, "We were going to have two products: compiler tools and shell tools. Open systems people will buy a bunch of SGIs, a bunch of HPs, a bunch of Unix machines. Well, we thought people who have the same environment would want to have the same tools."

This vision didn't work out. They sold no contracts that offered that kind of support. They did find, however, that people wanted them to move the compiler to other platforms. "The compilers people got from the vendors weren't as good and the compiler side of the business was making money from day one," says Henkel-Wallace.

The company began to specialize in porting GCC, the GNU compiler written first by Richard Stallman, to new chips that came along. While much of the visible world of computers was frantically standardizing on Intel chips running Microsoft operating systems, an invisible world was fragmenting as competition for the embedded systems blossomed. Everyone was making different chips to run the guts of microwave ovens, cell phones, laser printers, network routers, and other devices. These manufacturers didn't care whether a chip ran the latest MS software, they just wanted it to run. The appliance makers would set up the chip makers to compete against each other to provide the best solution with the cheapest price, and the chip manufacturers responded by churning out a stream of new, smaller, faster, and cheaper chips.

Cygnus began porting the GCC to each of these new chips, usually after being paid by the manufacturer. In the past, the chip companies would write or license their own proprietary compilers in the hope of generating something unique that would attract sales. Cygnus undercut this idea by offering something standard and significantly cheaper. The chip companies would save themselves the trouble of coming up with their own compiler tools and also get something that was fairly familiar to their customers. Folks who used GCC on Motorola's chip last year were open to trying out National Semiconductor's new chip if it also ran GCC. Supporting free software may not have found many takers, but Cygnus found more than enough people who wanted standard systems for their embedded processors.

Selling processor manufacturers on the conversion contracts was also a bit easier. Businesses wondered what they were doing paying good money for free software. It just didn't compute. The chip manufacturers stopped worrying about this when they realized that the free compilers were just incentives to get people to use their chips. The companies spent millions buying pens, T-shirts, and other doodads that they gave away to market the chips. What was different about buying software? If it made the customers happy, great. The chip companies didn't worry as much about losing a competitive advantage by giving away their work. It was just lagniappe.

Cygnus, of course, had to worry about competition. There was usually some guy who worked at the chip company or knew someone who worked at the chip company who would say, "Hey, I know compilers as well as those guys at Cygnus. I can download GCC too and underbid them."

Henkel-Wallace says, "Cygnus was rarely the lowest bidder. People who cared about price more than anyone else were often the hardest customers anyway. We did deals on a fair price and I think people were happy with the result. We rarely competed on price. What really matters to you? Getting a working tool set or a cheap price?"

17.2 HOW THE GPL BUILT CYGNUS'S MONOPOLY

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

The GNU General Public License was also a bit of a secret weapon for Cygnus. When their competitors won a contract, they had to release the source code for their version when they were done with it. All of the new features and insights developed by competitors would flow directly back to Cygnus.

Michael Tiemann sounds surprisingly like Bill Gates when he speaks about this power: "Fortunately, the open source model comes to the rescue again. Unless and until a competitor can match the one hundred-plus engineers we have on staff today, most of whom are primary authors or maintainers of the software we support, they cannot displace us from our position as the 'true GNU' source. The best they can hope to do is add incremental features that their customers might pay them to add. But because the software is open source, whatever value they add comes back to Cygnus.. . ."

Seeing these effects is something that only a truely devoted fan of free software can do. Most people rarely get beyond identifying the problems with giving up the source code to a project. They don't realize that the GPL affects all users and also hobbles the potential competitors. It's like a mutual disarmament or mutual armament treaty that fixes the rules for all comers and disarmament treaties are often favored by the most powerful.

The money Cygnus makes by selling this support has been quite outstanding. The company continues to grow every year, and it has been listed as one of the largest and fastest-growing private software companies. The operation was also a bootstrap business where the company used the funds from existing contracts to fund the research and development of new tools. They didn't take funding from outside venture capital firms until 1995. This let the founders and the workers keep a large portion of the company, one of the dreams of every Silicon Valley start-up. In 1999, Red Hot merged with Cygnus to "create an open source powerhouse."

The success of Cygnus doesn't mean that others have found ways of duplicating the model. While Cygnus has found some success and venture capital, Gilmore says, "The free software business gives many MBAs the willies."Many programmers have found that free software is just a free gift for others. They haven't found an easy way to charge for their work.

17.3 SNITCHWARE

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

Larry McVoy is one programmer who looks at the free source world and cringes. He's an old hand from the UNIX world who is now trying to build a new system for storing the source code. To him, giving away source code is a one-way train to no money. Sure, companies like Cygnus and Red Hat can make money by adding some extra service, but the competition means that the price of this value will steadily go to zero. There are no regulatory or large capital costs to restrain entry, so he feels that the free software world will eventually push out all but the independently wealthy and the precollege teens who can live at home. "We need to find a sustainable method. People need to write code and raise families, pay mortgages, and all of that stuff," he says.

McVoy's solution is a strange license that some call "snitchware." He's developing a product known as BitKeeper and he's giving it away, with several very different hooks attached. He approached this philosophically. He says, "In order to make money, I need to find something that the free software guys don't value that the businesspeople do value. Then I take it away from the free software guys. The thing I found is your privacy."

BitKeeper is an interesting type of product that became essential as software projects grew larger and more unwieldy. In the beginning, programmers wrote a program that was just one coherent file with a beginning, a middle, some digressions, and then an end. These were very self-contained and easily managed by one person.

When more than one programmer started working on a project together, however, everyone needed to work on coordinating their work with each other. One person couldn't start tearing apart the menus because another might be trying to hook up the menus to a new file system. If both started working on the same part, the changes would be difficult if not impossible to sort out when both were done. Once a team of programmers digs out from a major mess like that, they look for some software like BitKeeper to keep the source code organized.

BitKeeper is sophisticated and well-integrated with the Internet. Teams of programmers can be spread out throughout the world. At particular times, programmers can call each other up and synchronize their projects. Both tightly controlled, large corporate teams and loose and uncoordinated open source development teams can use the tool.

The synchronization creates change logs that summarize the differences between two versions of the project. These change logs are optimized to move the least amount of information. If two programmers don't do too much work, then synchronizing them doesn't take too long. The change logs build up a complete history of the project and make it possible to roll back the project to earlier points if it turns out that development took the wrong path.

McVoy's snitchware solution is to post the change logs of the people who don't buy a professional license. These logs include detailed information on how two programs are synchronized, and he figures that this information should be valuable enough for a commercial company to keep secret. They might say, "Moved auction control structure to Bob's version from Caroline's version. Moved new PostScript graphics engine to Caroline's version from Bob's."

McVoy says, "If you're Sun or Boeing, you don't want the Internet to be posting a message like 'I just added the bomb bay.' But for the free software guys, not only is that acceptable, but it's desirable. If you're doing open source, what do you have to hide?"

BitKeeper is free for anyone to use, revise, and extend as long as they don't mess with the part that tattles. If you don't care about the world reading your change logs, then it's not much different from the traditional open source license. The user has the same rights to extend, revise, and modify BitKeeper as they do GNU Emacs, with one small exception: you can't disable the snitch feature.

McVoy thinks this is an understandable trade-off. "From the business guys you can extract money. You can
