Autorentext
William "Bo" Rothwell At the impressionable age of 14, Bo crossed paths with a TRS-80 Micro Computer System (affectionately known as a "Trash 80"). 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 that experience, Bo's 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.
