The management would like me to remind you to be sensible and nice.

IRC: I idle on Libera as apocalyptech
(I've also historically been on Freenode as sekhmet, but have ditched it for Libera.)
Github: apocalyptech
Discord: apocalyptechheavyindustries (formerly apocalyptech#5237) xolotl
Mastodon: (Have a couple of these to guard against defederation splitting up my follows)
Twitter: Used to be @apocalyptech on there until Nov 27, 2022, but straight-up Nazi dogwhistles from Musk finally drove me off. No current account there.
Facebook: No.
