Thanks, as ever, go to my editor Simon St.Laurent and my technical reviewers Roy Owens, Tony Hammond, Timo Hannay, and Ben Lund. Thanks also to Mark Pilgrim, Jonas Galvez, Jorge Velázquez for their lovely code. Bill Kearney, Kevin Hemenway, and Micah Dubinko earned many thanks for their technical-reviewing genius on the first edition. Not to forget Dave Winer, Jeff Barr, James Linden, DJ Adams, Rael Dornfest, Brent Simmons, Chris Croome, Kevin Burton, and Dan Brickley. Cheers to Erhan Erdem, Dan Libby, David Kandasamy, and Castedo Ellerman for their memories of the early days of CDF and RSS and to Yo-Yo Ma for his recording of Bach's Cello Suite No.1, to which much of this book was written.
But most of all, of course, to Anna.
