With each book there is a chance to acknowledge and to thank those folks without whose support and help this book literally would have been impossible. First among them are Stacey, Robin, and Rachel Liberty.
I must also thank everyone associated with my books at Sams and Que for being professionals of the highest quality. The editors at Sams did a fantastic job, and I must especially acknowledge and thank Carol Ackerman, Christy Franklin, and Paul Strickland. A special thanks to Rich Halpert.
Finally, I'd like to thank Mrs. Kalish, who taught my sixth-grade class how to do binary arithmetic in 1965, when neither she nor we knew why.
