Start by learning docker, you don’t have to selfhost anything yet, just learn to run a container, specially to run automated stuff. Then learn to build the images and run docker compose.

Also you could start checking any form or infrastructure as code. I usually hear about ansible and nixos.
This helps having a way to redeploy your services in any hardware easily.

Does it apply it to all feeds? Or can it detect what feeds are actually Youtube ones?

I use rclone and duplicati depending on the needs of the backup.

For long term I use duplicati, it has a GUI and you can upload it to several places (mines are spread between e2 and drive).
You configure the backend, password for encryption, schedule, and version retention.

rclone, with the crypt submodule, you use it to mount your backups as am external drive, so you need to manually handle the actual copy of the data into it, plus versioning and retention.

I can’t give you the technical explanation, but it works.
My Caddyfile only something like this

@forgejo host forgejo.pe1uca
handle @forgejo {
	reverse_proxy :8000
}

and everything else has worked properly cloning via ssh with git@forgejo.pe1uca:pe1uca/my_repo.git

My guess is git only needs the host to resolve the IP and then connects to the port directly.

Ohhh! Now I understand!

Yeah, then that’s an issue on mastodon.
I mentioned some time ago, the fact that mastodon and Lemmy use the same protocol is annoying, because the experiences are different, so it causes a lot of issues :/

Unless lemmy devs have changed something since last year, this shouldn’t be the case, there’s a bug in there.

All interactions are recived by the instance hosting the community, and that instance is responsible for broadcasting that interaction to each instance where a user subscribed to it is hosted.
So, mastodon is only responsible for sending the upvote to feddit.dk and then feddit.dk to all other instances.

I’m not saying to delete, I’m saying for the file system to save space by something similar to deduping.
If I understand correctly, deduping works by using the same data blocks for similar files, so there’s no actual data loss.
