The worst I've ever had happen could be fixed with the (prompted) --allow-erasing flag, and I messed around with additional repositories a lot

Especially if you use https://continuwuity.org/ :3

Moderation tools are powerful but seperate to the server. Asgard.chat offers some hosted options, but meowlnir, Draupnir and policyserv are the usual tools.

Continuwuity.org has reasonable documentation, and you can (and should) disable signups or require a token to sign up.

MusicBrainz Cover art is from the Internet Archive's Cover Art Archive, and you can edit it easily via the musicbrainz.org website. You can also use https://harmony.pulsewidth.org.uk/ to update the medatata with stuff from streaming sites automatically.

Alternatively, you can install a plugin from Picard to download from, for example, Deezer or Apple Music. You can also grab a plugin to do replaygain, to get a more normalised audio volumes, like on streaming services.

For local music recommendations, you can try experimenting with listenbrainz local right now, if a bit experamental. It is essentially the Listenbrainz recommender on a local library. Building a better system for local music is on the MetaBrainz team's mind, and my final year project for University is going to be related as well (maybe follow me for updates if you're interested). I don't think automatically downloading from Spotify or whatever will happen though because of legal issues with that - maybe there'll be the ability to add plugins to do that. However, you can use the MusicBrainz database to get the exact Spotify link for many tracks (thanks to the Harmony importer lol). Ideally sharing libraries with your friends would be possible, though.

That page seemed outdated, but: From further down that page:

The recommended strategy is to share the keys automatically only to verified devices of the same user

This is the same situation where the key backup is accessible - which is not described on that page, but it's a key store of all the megolm keys. This is what is now generally used instead of that as it doesn't require devices to be online and allows recovering keys if all devices are lost.

A few days late, but I have a pretty similar usecase to you on https://forgejo.ellis.link/. My solution is go-away, https://git.gammaspectra.live/git/go-away, which just sits as a reverse proxy in between traefik and Forgejo. I haven't enabled fancy stuff like TLS fingerprinting. It's been effective enough at killing the bots downloading archives and DDoSing the server from residential IPs. My config is based on the example Forgejo config, but with a few tweaks. Too long to post here, though, so message me if you need access

https://continuwuity.org/ or https://forgejo.ellis.link/continuwuation/continuwuity

As for the difference: https://lemmy.world/post/33271240

"can't guarantee the authenticity of this message" just means it was restored from backup. In the same vein, if you can decrypt a message in any client, it should upload the keys to the message backup so it can be decrypted on other clients, even ones that haven't logged in.

I've only seen this message in the last months where different servers are having network issues and can't talk

Finetuning, self-hosting and whatever decentalised network they've got going on there aren't going to change the core of the technology. Oh, and it's a tiny local model (about 1/100th the size of cloud models), too, it's going to perform poorly compared to SOTA models anyway.

Honestly, this just seems like a consequence of alternative init systems not keeping up
