To Kara, Abbie, and Lauren—Quentin Docter
For Karen—Emmett Dulaney
For my wife, Karen. Your support continues to amaze me. None of this would be
possible without you. 143—Toby Skandier

Acknowledgments

It continues to amaze me how many people and how much time it takes to create a book of
this scope and size. From beginning to end, there are scores of dedicated professionals focused
on delivering the best book possible to you the readers.
First, I need to thank my co-authors Emmett Dulaney and Toby Skandier, as they did a
tremendous job while being under a serious time crunch. Now on to the rest of the team.

Jeff Kellum kept us on track and moving forward, which was a challenge at times. Daria
Meoli kept us organized, which is no small feat during writing. I owe special gratitude to Tech
Editor Neil Hester, who kept me on my toes and made excellent suggestions. Copy Editors
Linda Recktenwald and Sharon Wilkey provided their usual clairvoyance, and saved me from
butchering the English language. Many thanks also go out to the proofreader (James Brook),
indexer (Ted Laux), and compositor (Craig Woods). Without their great contributions this
book would not have made it to your hands.

—Quentin Docter

There are a great many people to thank but three are key; without them this book would
not be possible. First and foremost is Jeff Kellum of Sybex, who does his job extremely well
and pulls you along with him. Thanks must also go to David Groth for his excellent work on
the previous edition. I also thank the Production Editor (Daria Meoli); the Technical Editor
(Neil Hester); and the Copy Editor (Linda Recktenwald). Without their hard work, I would
have never completed this book.

—Emmett Dulaney

I would like to thank my Acquisitions and Development Editor, Jeff Kellum. Jeff has a
knack for matching me to the most interesting and challenging projects that enhance my
knowledge and proficiency in my area of expertise and then keeping me on track with them.
I’m indebted to my Technical Editor, Neil Hester, for catching some of the most detailed tech-
nical issues. This book is vastly more solid for his vigilance. My Production Editor, Daria Meoli,
and Copy Editor, Linda Recktenwald, have my deepest gratitude for repairing those things in
which I am most certainly not expert.
In addition, I’d like to thank the proofreader (James Brook), indexer (Ted Laux), typesetter
(Craig Woods), and CD developers (Angela Denny and Kit Malone).
Thank you to my Embarq Corporation management team and associates for the support
and challenges you continue to offer.

Finally, thank you to my incredible kids, Toby, Tiffani, Trey, and Taylor. You guys support
and encourage your dad through your own hard work and determination. You’re always in
my thoughts and plans.

—Toby Skandier
