There are surely native totp apps for this on Linux and I haven’t used Ubuntu in a million years but if you really want to do specifically this maybe waydroid.
I did 10 hour shifts 1 hour or 1 hour banked for a few years from 4am. The latest start time to avoid being stuck behind a 4 day long train and get home before traffic hits standstill for hours that worked for everyone that needed to be on site for the same shifts. Probably something similar I’d say because while the shifts were different in later jobs many featured seasonal meetings to discuss adjusting the shift times for the same reasons.
I didn’t try pfsense but it sounded like opnsense suited me better and I have had no reason to change so far. It has also made managing my self host stuff so much easier but a lot of it is pending being redone with more future proofing.
This one didn’t age quite as poorly as some of the others. I have gotten to the point of generally preferring Linux gaming now though. Bsd is still a bit lacking for my general computing but opnsense on my router is one of those ‘where has this been all my life?’ things.
Either windows 95 or 98 I used to play this game my mom set up for me but doesn’t remember. Now she needs my help to plug in a USB cable but somehow has a job that uses software and procedures too complicated for me… Anyway I can remember if it was entirely this or just part of it, but the memorable part was the sliding puzzles, like the ice caves in Pokemon. The character might have had skates or something but it’s a vague memory that could be wrong.
