Acknowledgments

Time to climb up on stage, grab the microphone, and tearfully thank every relative, friend, and acquaintance I've ever known, while the audience gradually slips off to the Land of Nod and viewers worldwide start channel hopping. "Oh my God, I love you all, I really do."

First, I should thank you for buying this book, which will mean that I can buy a Tivoli chocolate-like bar when I go for lunch. If you haven't bought this book, then why are reading this bit? Are you desperate or something?

My wife, Supatra, and son, John, have been a constant support, especially when my back is causing problems.

Thanks to my current and past department heads, Ajarns Pichaya, Sinchai, Amnuay, and Weerapant, and many other staff and colleagues, who have let me potter about on this mighty edifice. But why does my office have the word "Broom Cupboard" stenciled on the door? But seriously, Prince of Songkla University is a great place to work.

Greetings to the numerous students who have suffered as guinea pigs for various parts of this book. Your looks of incredulity and boredom were a wondrous spur: "Goodbye Mr. Chips" should be banned.

Special thanks to the hundreds of people who have sent me emails saying how useful the online book has been; their kind words have been a great source of encouragement. I've also received suggestions about how to improve the book and a few bug reports. I credit those people at the relevant places in the text.

Finally, my best regards to O'Reilly and my editor Brett McLaughlin and figures illustrator Chris Reilly, who have knocked this book into better shape. Any remaining rough edges are due to me.
