I thank the team at Apress who made this book possible: Steve Anglin, Corbin Collins, Jim Markham, and Jill Steinberg. Working with all of them was a real pleasure and I can with confidence recommend them to any author. I also want to thank the tech reviewers: Charles Cruz, Shane Kirk, and Eric Neff. They provided invaluable feedback, often catching mistakes I would not have seen even after dozens of readings. To all my friends whom I did not get to see as often as I would have liked while I was working on this book, I give my thanks too: Marcely, Mathieu, Marilen, Maurice, Katie, Maggie, Jean-René, Ruby, Greg, Aline, Amy, and Gilles, I promise I will make up for the lost time. Last but not least, I owe a lot to three people: Eddy Derick, Fabrice Bernard, and Jean-Louis Gassée. Sometimes all it takes is an injured toe and a broken suitcase.
