William “Bo” Rothwell At the impressionable age of 14, William “Bo” Rothwell 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 this 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. Denise Kinsey, Ph.D, CISSP, CISCO Dr. Denise Kinsey served as a Unix administrator (HP-UX) in the late 1990s and realized the power and flexibility of the operating system. This appreciation led to her home installation of different flavors of Linux and creation of several academic courses in Linux. With a strong background in cybersecurity, she works to share and implement best practices with her customers and students. Dr. Kinsey is an assistant professor at the University of Houston.
