Thanks go to everyone who helped with the first edition: James Duncan, Douglas N. Arnold, Bill Fenner, Ken Hornstein, Scott Dickson, Dan Ehrlich, Felix Lee, Scott Schwartz, Gregory P. Smith, Dan Sully, Karol Jurado, and Gina Steele. For the second edition, I’d especially like to thank Jordi Gutiérrez Hermoso for his excellent technical review work; his suggestions and corrections have been invaluable. Thanks also to Dominique Poulain and Donald Karon for providing some excellent early-access feedback, and to Hsinju Hsieh for putting up with me during the process of revising this book.

Finally, I’d like to thank my developmental editor, Bill Pollock, and my production editor, Laurel Chun. Serena Yang, Alison Law, and everyone else at No Starch Press have done their usual outstanding job at getting this new edition on track.
