Because he had used UNIX before (and had even written programs in BASIC), he was considered “technical” and started out writing about computer network protocols. Over the next eight years, Chris helped write (and rewrite) the thousands of pages of docu- mentation that accompanied the UNIX operating system. He stayed with the same organiza- tion, even after AT&T spun it off into UNIX System Laboratories and then to Univel, before the organization was sold (with the UNIX source code) to Novell in 1992. (Yes, this is the infamous SCO source code!) Over the following decade, Chris wrote or contributed to about a dozen UNIX books. In 1999, he made the transition to Linux with a vengeance when he wrote Red Hat Linux Bible. Since that time, the book has become a computer book bestseller and in its various editions has sold well over 240,000 copies worldwide. Between editions of Red Hat Linux Bible, Chris wrote Linux Bible, 2005 Edition and co-wrote Linux Troubleshooting Bible with Thomas Weeks. (Tom contributed two chapters to this book as well.) The original Linux Toys and now Linux Toys II reflect Chris’s attempts to put together open source software into fun and useful projects. The projects in this edition reflect Chris’s collabo- ration with leaders and maintainers from a handful of excellent open source initiatives. 01_579959 ffirs.qxd 9/27/05 10:33 PM Page vi Credits Executive Editor Carol Long Acquisitions Editor Debra Williams Cauley Development Editor Sara Shlaer Technical Editors Bharat Mediratta (Gallery) Brandon Beattie, François Caen (MythTV) Roberto De Leo (eMoviX) John Andrews, Robert Shingledecker (Damn Small Linux) Charles Sullivan (Heyu X10) Tim Riker (BZFlag) Heiko Zuerker (Devil-Linux) Michael Smith (Icecast) Jim McQuillan (Linux Terminal Server Project) Contributing Authors Thomas Weeks Jesse Keating Copy Editor Nancy Rapoport Editorial Manager Mary Beth Wakefield Production Manager Tim Tate Vice President and Executive Group Publisher Richard Swadley Vice President and Executive Publisher Joseph B.
