I program #SpringBoot web services and have now managed to avoid managing people. I used to program dev tools & before that, program mobile phones.

Once ran the same early Windows 8 build instance on both a hypervisor and native boot.

Old enough to remember #Symbian #C++.

I really like painting miniature figures like those produced for #warhammer, but am not so keen on #GamesWorkshop.

#OnePageRules is my current #TableTop #Wargaming jam.

Involved in some kind of computer bullshit.

Be advised: I edit my toots a lot. Almost all of it proofreading.

Blatantly, unabashedly pro-democracy. Ex-Michigan farmboy makin' it work since 1958 (born in 1953, but coasted for a few years). Proud and concerned father, grandfather, dog dad, and atheist. Emigrated from New Mexico high desert to New Jersey lake, spring 2022. Used to be a whitewater canoeist, now happy paddling a quiet lake. ClassicPress/WordPress developer; websites for real estate agents. I smoke a pipe, therefore I'm a philosopher. Oxford comma because I'm civilized.

Ik roei, speel met kleine zeilbootjes #df65 of mijn #SpringerTug (beiden #rc) en soms met taal.
Fan van #linux (al ben ik er nu wat minder actief mee bezig). En als trouw luisteraar van #damnhoney zou ik me bijna #feminist kunnen noemen.
