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% hostname tilde.town 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 tilde% uptime 21:38:01 up 156 days, 17:15, 454 users, load average: 3.82, 4.40, 4.19 tilde% 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. - Dan C.
