Mark Kampe has retired from a very rewarding career in operating systems, working as a developer, architect, team lead, manager, and in staff and engineering executive roles from 1972-2017. He has worked extensively in OS ports, file systems, multi-processor support, distributed systems, high availability, high performance, and development tools for both start-ups and enterprise software companies.
He has also (since 2001) taught Computer Science (at UCLA, Pomona, and Harvey Mudd) where he enjoys sharing his experience in Operating Systems and Software Engineering, acting as a Clinic advisor, and playing in the lab with intro programming students.
Recreationally, he has done fencing (unlikely favorite is epee), rock-climbing (mostly local bouldering with friends who are much better), back-packing (east side of the southern Sierras), skiing (alpine, also with friends who are much better), running, flying (power and sail planes), Tarot and Kabbalah, Fantasy Role Playing games (creating cultures and games, GMing my own games, and playing in campaigns run by others), restoring classic English (TR3A, Jensen Healey) sports cars, and SCUBA diving/instruction. His reading is comparably ecclectic, but the recurring themes (in non-fiction) seem to have been portfolio management, history/biographies, language/anthropology and physics/cosmology.
