You’d think the more books you write, the easier it would get. This is false. My thanks to my wife Marisa, who has managed to put up with the stress of living with a tech book author. Luckily, a lot of very smart people have helped me make this book a reality. My thanks to Cliff Colby, my stalwart editor. Liz Welch has once again managed to make my words make more sense than I could on my own. Thanks, Liz. My thanks to David Van Ness and everyone on the production team for making this book look as great as it does. And my thanks to everyone at Peachpit who helped out. I would be remiss if I didn’t also thank my boss, Dan, for supporting my non-work-related activities.
