@pft@infosec.exchange @hrbrmstr@mastodon.social sounds like a lot of hobbies to me... :⁠-⁠) including the learning opportunities which come from investing so much time into group related activities where you organize stuff...

@yvanspijk@toot.community does the word puddle also come from the same ancestor as pit? Sounds so similar to German Pfütze...

Replying to @warandpeas@mastodon.social
@warandpeas@mastodon.social I interpreted "panel by panel" add one panel per post and not "all four panels as a picture on it's own but in a single post". And choose the other option... I would prefer 4 individual panels in a single post.

@yvanspijk so "cling to life" is now similar to the mountain with the name which basically means mountain 4 times or so?

@bmarinov@hachyderm.io thank you, the short summary is already helpful! I'm looking for a good alternative for a docker compose based homelab, so your comment re rustfs is ... Helpful :⁠-⁠)

Replying to @andrewnez__dup_21468@mastodon.social
@andrewnez internally we use PG to version data. We have commits, branches, diffs, merges, cherry picks,... Internally, data is kept in tables with branch_id, commit_id_from, commit_id_to, data_pk, with some range based exclision constraint. Branching is expensive, as it needs to copy the whole data set (~150 tables, diffing has some hints to make it not read all tables but only the touched ones.

@r0b0 @daandemeyer @pid_eins naming it after the windows terminology would have so much more flamewar potential...
