I don’t think they state anywhere that they adhere to semantic versioning.

Please read the warning at the top of their page:

⚠️ The project is under very active development. Expect bugs and changes. Do not use it as the only way to store your photos and videos!

If you don’t like these breaking changes, this might not be the right software for you (for now).

I named my PiHole holypi

And they started sending advertisement emails to people who registered on gitea.com.

mailbox.org is 3€/month or 30€/year if you bring your own domain.

If you are going for a reverse proxy, I highly recommend using Caddy. Issuing TLS certificates is all done automatically and reverse proxy headers are all automatically set.

In many cases, this simple config is enough:

example.org {
    reverse_proxy localhost:1234
}

FYI encoding wise, it’s unlikely that you can hear a difference between FLAC and e.g. Opus if you rip the audio from a CD.

That’s just your lemmy client that extracts all links from the post. I can’t see any fault on OP’s side here.

Shouldn’t they be kept mirrored to other instances?

Caddy is the way to go.

Git itself is already distributed. For federated issues/pull requests, there is the ActivityPub extension ForgeFed. Forgejo ist actively working on implementing it.

I didn’t try CoreOS as I didn’t even get how to set it up. As I understand it, it uses a completely different workflow for administering the system compared to regular distros.

You can use Fedora IoT which is essentially rpm-ostree based Fedora Server. It would be less confusing if it was just named Fedora Atomic Server.

Where RSS?

A Free Software License is even more important. There are many great projects out there which you can’t modify etc. because the project isn’t distributed with a license (which means “all rights reserved” in most jurisdictions).

You can also set SELinux to permissive mode. https://docs.fedoraproject.org/en-US/quick-docs/selinux-changing-states-and-modes/#_changing_to_permissive_mode

This way it is basically disabled, but you can reenable it without any problems.

I recommend using https://regex101.com/

It explains all parts of your regex and highlights all matches in your example text. I usually add a comment to a regex101 playground if I use a regex in code.
