From Ben Collins-Sussman

Thanks to my wife Frances, who, for many months, got to hear, «But honey, I'm still working on the book», rather than the usual, «But honey, I'm still doing email.» I don't know where she gets all that patience! She's my perfect counterbalance.

Thanks to my extended family for their sincere encouragement, despite having no actual interest in the subject. (You know, the ones who say, «Ooh, you're writing a book?», and then when you tell them it's a computer book, sort of glaze over.)

Thanks to all my close friends, who make me a rich, rich man. Don't look at me that way—you know who you are.
