Didn't really hop much, started with Windows, went on to OSX, got annoyed at it and ran Arch in a VM until I was comfortable with it, then went bare-metal with it.

Happy Arch user for some years now, though recently I'm using Fedora for work and I really like it. It's not a good fit for some machines I'm running which need a lot of customisations to run properly.

If a user is in the docker group they can also run docker commands.

Und ich hab letztens meinen Krichenaustritt per Mail und digital signiert an die BH geschickt und von denen nie auch nur irgendeinen Pieps gehört. Von der Kirche kam dann 2 Monate später die Frage, ob ichs mir nicht vielleicht doch anders überlegen wolle. Und das in einem Steinzeitstaat wie Österreich.

Better check, you definitely already have a firewall running since docker needs it for NAT. A fresh debian has, as far as I know nftables and iptables-nft installed.

Whenever my fiio runs out of power. About once a week.

Syncthing on my Kobo and all other devices where I want access to my books.

I recently wrote a script which finds duplicate files and hard links them. I can share it with you, though there are no guarantees of it's safety. There are probably better already established tools out there.

I have a cheap Kobo and put KOReader and Syncthing on it.

With the limited info you have given my first thoughts would be: dns: ipv6 vs 4; firewall; basically anything network related
