Many, many thanks to Ann Sellers, both for agreeing to do this book and for being such a delight to work with.

Thanks to Ebony Haight for coordinating the technical review (as well as everything else I don't know about).

Thanks to my agent, Laura Lewin of StudioB, without whom this book would not exist.

Thanks to the technical reviewers, including Paul Bain, Kevin Bentley, Evan Campbell, Thomas Duff, Bill Higgins, Bob Kemmerer, Scott Rich, Alex Rosenberg, and Satadip Dutta for taking the time to provide such excellent feedback. I would like to thank Sylvain Gibassier and Kevin Hammond in particular for supplying such excellent feedback. Any remaining mistakes are my own.

On a personal note, thanks to my friends and family for their support. And finally, thanks to Cynthia, Diane, and Mom. You are, quite simply, the best.
