Throughout the long hours I have spent writing this book, many people have helped me to accomplish this project. I would like to thank my closest friends LaWanda Tetteh and Gleb Tulukin for giving me support and encouragement when I needed it. Special credit goes to Amie Koker for being patient and understanding and to Tricia Riviere for her sense of humor and quick wit. Troy Davis and Yves Noel have been great in sharing their technical and personal views and in reviewing my work. This book would not have been possible without Todd Green, Sean Dixon, and the rest of the team at Sams Publishing who shared their expertise and professionalism. I want to express my appreciation to everyone, mentioned here or not, who has helped me in completing this goal.
