Things we see all the time, but no one can really describe, like
Docker
Federated
Self host
Fork
Container
Instance
Flatpak
Tailscale
Distro
Wayland
Nginx
Etc.
Sure we can search but the terms are just so abstract I can’t understand some of it.
*this is for helping some new users as well as myself -
I think the only “required” one on your list is Instance: It’s one out of many servers. Lemmy.world, sh.itjust.works, etc.
I find it useful to think of it topologically like an IRC server, if you’re familiar with how those work; many of them connect and share content - You’re on an instance/server, but can interact with users and content from different ones.
The rest are more oriented towards Linux, servers (in general), and aren’t really required for Lemmy use in general.
This is where I started to explain what a codebase fork is, but then I realized that I fucking hate typing on my phone.
