Projects like this don’t happen without the hard work and dedication of a supporting cast. I would like to thank the wonderful people at Pearson for asking me to write this book in the first place. Opportunities like this don’t happen often, and I am extremely grateful for the chance to write my very own book. Drew Cupp deserves special acknowledgment because his patience and attention to detail are particularly infectious and much appreciated. The technical editors, Bill Huisman and Ryan Lindfield, kept me honest. This is very important because in attempting to distill technical ideas for the purpose of an Exam Cram, sometimes the explanations of these ideas become at best over-simplified, and at worst inaccurate. Last, but certainly not least, I would like to thank my family, wife Carol Ann and children Scott and Meaghan. Without their support and encouragement, I could not have maintained the enthusiasm and creativity that is necessary to do a good job.
