I'm a grandfather, a Dudeist, and a playful retiree. I've been addicted to computers since 1978 - both professionally (from SIGINT officer to IT pro) and privately (from the ZX81 to modern workstations). When I’m not in front of a screen, you’ll find me sport hiking (from the Himalayas to Megamarsch events), reading or writing (sci- and other fiction), or tending to my hydroponic garden.
