A family of tinkerers.
My dad worked at DuPont/Berg Electronics, the home of Berg connectors. My uncle Tom was a senior systems analyst at the FDA who built R/C planes for the Civil Air Patrol. Our house had PCBs and capacitors where other houses had LEGOs, and we got a computer before most of the kids I knew. At eleven I found BBSes, then a dialup Unix shell, then IRC.
