I teach about the R programming language, SQL, and Raspberry Pi. When I'm not being serious, I write science fiction and play in boats.
I've been playing with technology for as long as I remember. My dad was a design engineer and brought home an early-stage 8080 micro-computer for me to program. I learned BASIC on a time-share system, played with electronics, found out how to reset the house circuit breakers ("Mark," my mother would shout. "Are you okay? What was that BANG I heard?") At university I picked up a degree in Industrial Education, worked in the software industry as a developer evangelist, then re-entered the education world through Lynda.com. I am now a full-time instructor and consultant, focused on R, SQL, and Raspberry Pi. When I have a need, I play with python, C++, php and small electronics.
