About the Reviewer
Walt Stoneburner is a software architect with over 20 years of commercial application development and consulting experience. Fringe passions involve quality assurance, configuration management, and security. If cornered, he may actually admit to liking statistics and authoring documentation as well.
He's easily amused by programming language design, collaborative applications, and ASCII art. Self described as a closet geek, Walt also evaluates software products and consumer electronics, draws cartoons, produces photography, writes humor pieces, performs slight of hand, enjoys game design, and can occasionally be found on ham radio.
Walt may be reached directly via email at wls@wwco.com. He publishes a tech and humor blog called the Walt-O-Matic athttp://www.wwco.com/~wls/blog/. Rumors suggest that some of his strange videography may be found on iTunes.
Currently he is employed at Business & Engineering Systems Corporation as a lead engineer developing advanced software solutions for knowledge management.
Other book reviews and contributions include AntiPatterns and Patterns in Software Configuration Management (ISBN 0-471-32929-0, p. xi) and Exploiting Software:
 How to Break Code (ISBN 0-201-78695-8, p. xxxiii).

Authoring a book is not an easy feat. However, the help and guidance from my family and friends helped me to author this book. First, I would like to thank Packt Publication for providing me an opportunity to work on such an exciting project. I would like to thank my parents for their constant encouragement. Special thanks to my friends Shrikant Khare and Sormita Chakraborty for their support and encouragement.
