Acknowledgments
This book could not have been written without the help of all the people who contributed to it. To start, I want to thank the people at PearsonDenise Lincoln and Ellie Bru in particular. Weve worked a lot together over the past years, and this book is another milestone on our road to success! It has been fantastic how you both have helped me to realize this book in just two months!
Next, I want to thank my technical reviewers. Big thanks to Bo and John! Thanks to your great feedback, Ive been able to apply important improvements to the contents of this book. Also, a special thanks to Etienne Esterhuizen, from New Zeeland and Santos Venter Chibenga, and Robert Charles Muchendu from the African Living Open Source Community, who helped me as volunteer reviewers. And last but not least, thanks to my fellow instructor and colleague Pascal van Dam, who helped me make some important last-minute improvements.

William Bo Rothwell crossed paths with a TRS-80 Micro Computer System (affectionately known as a Trash 80) at the impressionable age of 14. Soon after, the adults responsible for Bo made the mistake of leaving him alone with the TRS-80. He immediately dismantled it and held his first computer class, showing his friends what made this computer thing work.
Since this experience, Bos passion for understanding how computers work and sharing this knowledge with others has resulted in a rewarding career in IT training. His experience includes Linux, UNIX, and programming languages such as Perl, Python, Tcl, and BASH. He is the founder and president of One Course Source, an IT training organization.
