Trivia: Did you know that, until 1973, #Unix reset the Epoch every year? The first epoch was 1971-01-01, the second 1972-01-01, & the third 1973-01-01, & time from all three were measured as 60th of a second, guaranteeing an overflow every 2 years. https://stackoverflow.com/questions/11573024/when-was-unix-epoch-time-revised-from-1971-to-current-1970-value

The OS I use daily is turning 50, depending on how you define its start. #Unix50
On #Unix's 40th birthday, the IEEE's Spectrum magazine told of its start like this: https://web.archive.org/web/20190228090043/https://spectrum.ieee.org/computing/software/the-strange-birth-and-long-life-of-unix/0
The 50th anniversary of Unix is particularly reminding me of my age because I was born within days of its manual's first edition: https://www.bell-labs.com/usr/dmr/www/1stEdman.html
Thankfully, *that* anniversary is still 2 years off. :p
