ACKNOWLEDGMENTS
I would like to thank Bill Pollock, Karol Jurado, Andy Carroll, Leigh Sacks, and everyone else at No Starch Press for making this book a possibility and allowing me so much creative control of the process. Also, I would like to thank my friends Seth Benson and Aaron Adams for proofreading and editing, Jack Matheson for helping me with assembly, Dr. Seidel for keeping me interested in the science of computer science, my parents for buying that first Commodore Vic-20, and the hacker community for their innovation and creativity that produced the techniques explained in this book.
