No book is ever written by just one person. There are always people working behind the scenes to make it come together. I'd like to thank my editors, Neil Alexander and Neha Nagwekar, for proposing the idea for this book and for guiding it to completion. Thank you for your faith in me. I also want to thank Sageer Parkar for coordinating the project and keeping us all on task. Thanks also goes to my technical editors Harshad Vairat and Novina Kewalramani. Their attention to the small details was invaluable. I also want to thank my reviewers Matt Goddard and Jan Tomá?. Additional thanks goes to my friends and colleagues Svetlin Denkov, Marina Lin, and Larry Vance, who read rough draft chapters and provided feedback and encouragement throughout the project. This book would not have come together without their support and honest critique. Thanks also to Ezra Schwartz, who encouraged me to pursue the project and provided advice and inspiration along the way. And finally, a special thanks to my wife, Kathy, who offered encouragement, patience, and understanding during long nights and weekends at the keyboard. Her belief in me makes everything I do possible.
