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 and friends for their sincere encouragement, despite having no actual interest in the subject. (You know, the ones who say, “Ooh, you wrote a book?”, and then when you tell them it’s a computer book, they 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.

Thanks to my parents for the perfect low-level formatting and for being unbelievable role models. Thanks to my kids for giving me the opportunity to pass that on.
