I thought some folks here might find this interesting. Someone else
today reminded me of tilde.town, which is a publicly accessible
machine running Linux. They have a shocking amount of use:
tilde% uname -a
Linux tilde.town 5.15.0-58-generic #64-Ubuntu SMP Thu Jan 5 11:43:13
UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
21:38:01 up 156 days, 17:15, 454 users, load average: 3.82, 4.40, 4.19
Not quite a thousand users logged in simultaneously, but half that. If
one counts the number of processes associated with pseudoterminals,
it's more (I guess a lot of users are running tmux and/or screen).
The system is also surprisingly modest: 6 cores, 16GiB of RAM and
about 1TB of storage.
It's surprisingly zippy.
