1. Acknowledgments

This is just a book about the free software movement. It wouldn't be possible without the hard work and the dedication of the thousands if not millions of people who like to spend their free time hacking code. I salute you. Thank you.

Many people spoke to me during the process of assembling this book, and it would be impossible to cite them all. The list should begin with the millions of people who write and contribute to the various free software lists. The letters, notes, and postings to these lists are a wonderful history of the evolution of free software and an invaluable resource.

The list should also include the dozens of journalists at places like Slashdot.org, LinuxWorld, Linux magazine, Linux Weekly News, Kernel Traffic, Salon, and the New York Times. I should specifically mention the work of Joe Barr, Jeff Bates, Janelle Brown, Zack Brown, Jonathan Corbet, Elizabeth Coolbaugh, Amy Harmon, Andrew Leonard, Rob Malda, John Markoff, Mark Nielsen, Nicholas Petreley, Harald Radke, and Dave Whitinger. They wrote wonderful pieces that will make a great first draft of the history of the open source movement. Only a few of the pieces are cited directly in the footnotes, largely for practical reasons. The entire body of websites like Slashdot, Linux Journal, Linux World, Kernel Notes, or Linux Weekly News should be required reading for anyone interested in the free software movement.

There are hundreds of folks at Linux trade shows who took the time to show me their products, T-shirts, or, in one case, cooler filled with beer. Almost everyone I met at the conferences was happy to speak about their experiences with open source software. They were all a great source of information, and I don't even know most of their names.

Some people went beyond the call of duty. John Gilmore, Ethan Rasiel, and Caroline McKeldin each read drafts when the book was quite unfinished. Their comments were crucial.

Many friends, acquaintances, and subjects of the book were kind enough to read versions that were a bit more polished, but far from complete: L. David Baron, Jeff Bates, Brian Behlendorf, Alan Cox, Robert Dreyer, Theo de Raadt, Telsa Gwynne, Jordan Hubbard, James Lewis Moss, Kirk McKusick, Sam Ockman, Tim O'Reilly, Sameer Parekh, Bruce Perens, Eric Raymond, and Richard Stallman.

There are some people who deserve a different kind of thanks. Daniel Greenberg and James Levine did a great job shaping the conception of the book. When I began, it was just a few ideas on paper. My editors, David Conti, Laureen Rowland, Devi Pillai, and Adrian Zackheim, were largely responsible for this transition. Kimberly Monroe suffered through my mistakes as she took the book through its production stages. They took a bunch of rambling comments about a social phenomenon and helped turn it into a book.

Finally, I want to thank everyone in my family for everything they've given through all of my life. And, of course, Caroline, who edited large portions with a slavish devotion to grammar and style.
