Acknowledgments
As we were putting together this book, I was reminded of the proverb that begins “It takes a small village….” That beginning definitely holds true to create a book of this scope and size. From beginning to end, scores of dedicated professionals have focused on delivering the best book possible to you, the readers.
First, I need to thank my coauthor Jon Buhagiar. I appreciate him diving in and dedicating himself to helping to produce an excellent book. I also need to give special thanks to our technical editor, Chris Crayton. He was meticulous and thorough, and challenged me to always find new and better ways to communicate complex concepts. His entire focus was on providing the best training material possible, and I doubt there’s better in the business. Now, on to the rest of the team.
Kenyon Brown and Tom Cirtin kept us on track and moving forward, which was a challenge at times. Christine O’Connor had the fun job of keeping us organized, which is akin to herding cats. Copyeditor John Sleeva reminded me yet again that I am no master of the English language and saved me from butchering it (too badly). Many thanks also go out to proofreader, Nancy Carrasco and our indexer, Ted Laux. Without their great contributions, this book would not have made it into your hands.
On a personal note, I need to thank my family. My girls are all incredibly supportive. Unfortunately, writing a book as my slash while holding down a full-time job takes up a lot of time. I end up hiding in my office a lot, but they’re always there for me, and I couldn’t do it without them. Another huge thanks goes to my late grandpa, Joe, who got me into computers and taught me so many lessons I will never be able to repay. Finally, thanks to my friends who keep me relatively sane—Sean, Kurtis, Tim, John, and others—and laugh at me when I tell them I spent my weekend writing about the laser printer imaging process.
—Quentin Docter
I would like to first thank my coauthor Quentin Docter. Throughout the writing of this book, he helped me with his insight and his expertise in writing technical books. Without his words of wisdom and guidance, this book would not be the product it stands to be. I would also like to give special thanks to our technical editor, Chris Crayton. His thorough review of the material helped to identify many areas to elaborate on and polish.
I would also like to take the time to thank the many people who made this book possible: Kenyon Brown, at Wiley Publishing, for giving me the opportunity to write this book and work with this wonderful team; Tom Cirtin, for keeping us on track during the writing process; Christine O’Connor, who also kept us on track and organized during the publishing process; and our copyeditor, John Sleeva, for helping me realize my use of IT slang at times and proper English. I’d also like to thank the many other people I’ve never met but who worked behind the scenes to make this book a success.
During the writing of this book, many others in my life supported me, and I’d like to take this opportunity to thank them, as well. First and foremost, thanks to my wife and son for their support during the many evenings and weekends spent in my office at the computer. Finally, thanks to my friend and co-worker, Bill, for encouraging me daily with his insight and jokes, as well as to all of my other co-workers and friends. Thank you.
