This is an excellent explainer:

Мой отчёт об #ICFPC2024: https://blog.tty8.org/posts/2024-07-06-icfpc-2024.html Это было круто! Один из лучших контестов за все десять лет, что я в них участвую.

If you believe that main() is the first bit of code that gets to run, and ever wondered how globals are initialized then, this article is just for you: http://dbp-consulting.com/tutorials/debugging/linuxProgramStartup.html

I guess it's time for me to learn #systemd properly. Just wasted half an hour trying to figure out why /home gets auto-mounted when I SSH into the box; it shouldn't be, because I commented it out of /etc/fstab.

Turns out systemd has a "mount unit" for every configured file system, and when you edit /etc/fstab, you're supposed to run systemct daemon-reload for systemd to apply the change, otherwise it'd stubbornly restore the system to the state it believes correct.

It's now possible to set a #Mastodon post's language with a drop-down: https://github.com/mastodon/mastodon/pull/18420 No more mis-identified languages in posts!

(I assume this will be part of the 3.5.3 release.)

LibreTranslate is a self-hostable replacement for Google Translate: https://libretranslate.com/ There are a bunch of public instances too: https://github.com/LibreTranslate/LibreTranslate#mirrors

That makes it one more piece of data that you don't have to feed to Google anymore :)
