I'll start. Did you know you can run a headless version of JD2 on a raspberry pi? It's not the greatest thing in the world, but sometimes its nice to throw a bunch of links in there and go to sleep.
I'm just now dipping my toes into docker. I started off self hosting a bitwarden server, and im working on moving my *arrs over to containers on my nas. I need a bit more experience before i move my seedbox over fully, dont need any more isp letters.
