Acknowledgments

Many people helped us with this book. Without their assistance, we would still be on the third chapter. Brian Baldwin (Atlantic Coast Telesys), John Guthrie (Psynapse Technologies), Randal Hanford (Boeing, University of Washington), Martha McNeil (JHU), Rich Slywczak (NASA), and Dan Unger (Eagle Design and Management) provided valuable technical feedback on many different chapters. Their recommendations improved the book considerably.

Others providing useful suggestions or corrections include Evan Atkinson, Abhay Bakshi, Eliezer Bulka, Joe Bunag, Bob Caviness, Brian Deitte, Pete Fritsch, David Geary, Darryn Graham, Peter Gray, Vladimir Gubanov, Kalman Hazins, Lis Immer, Mike Jenkins, George Jensen, Lian Jin, Rob King, Ashley Lan, Christian Malone, Doug Parker, Ann Platoff, Alexander Pyle, Patrick Quinn-O'Brien, Mark Roth, Hong Sung, Frank Tanner, Jeff Thorn, Alex Turetsky, Kris Uebersax, and Elissa Weidaw. I hope I learned from their advice.

Mary Lou "Eagle Eyes" Nohr spotted my errant commas, awkward sentences, typographical errors, and grammatical inconsistencies. She improved the result immensely. Vanessa Moore designed the book layout and produced the final version; she did a great job despite my many last-minute changes. Greg Doench of Prentice Hall believed in the concept from before the first edition and encouraged us to write a second edition. Thanks to all.

Most of all, Marty would like to thank B.J., Lindsay, and Nathan for their patience and encouragement, and Larry would like to thank Lee for her loving and unfailing support. God has blessed us with great families.
