I am grateful to the impressive roster of tech editors who helped me shape this book and provided me with feedback. In alphabetic order, the ones who saved my reputation in a couple of instances are: Adonis Bitar, Arsen Yeremin, Bertrand Le Roy, Christoph Wille, Mike Pope, and Tobias Hauser.
Also, I am indebted to my editor John Osborn who guided me through this project. He is the only editor I know who ever complained when I was submitting material before the negotiated deadline. But it was his excellent project management that allowed me to focus on writing and doing so in due time.
Finally, I have to admit that I am not too keen on personal acknowledgments, thanking family members, husbands/wives/fiancées/partners, and cats/dogs. (The only exception is Richard Hundhausen who once expressed his gratitude that there were no 24-hour divorce services where he lived.) However, I would like to take this opportunity to thank my parents. They were very supportive when I worked my first book, and now, about 50 books later, I finally show some appreciation. Embarrassingly, they sometimes even find mistakes without knowing the technologies involved: some time ago, my father noticed that there were more opening than closing parentheses in a listing. So: thanks Mom, thanks Dad. And—now that I am into it—thanks to my friends and family who do not seem to mind when I have long writing phases or am on the road for yet another conference.
