@syncros @gnomon I think my section of the university was all quiet for Y2K but we were running straightforward Unix stuff at the time. I'm sure the big central systems had a lot of work.
I hope to be retired by 2038 but I'll probably still be using Unix systems (eg, a desktop), so I'll get to have fun times anyway. Plus all the online stuff falling over. At least TLS certificates don't have Y2038 issues (... they have other ones, timestamps in them are fun times).
