Airsonic music server… There are a few quirks getting it all set up properly, but once it works, it just seems to work forever. Samba file sharing server. Also miniDLNA server can make it easy to watch your movie collection on a tv. The airsonic DLNA doesn’t seem to be working currently. I also have a few mastodon bots running from a Pi4. Also could run a tor relay node, which would make it so it’s less idle. I have a lot of stuff on my Pi4 and it is still mostly idle most of the time. Thats fine though. For me it’s not a huge problem, since overall, my goal is to make it use as little power as possible for all those things. I think thats the whole point is to really use the most lightweight computer that can do what you need. If you just need the print server, you could always get a lower power Pi so you can really optimize how much power needs to be used and maybe even do some sort of Wake on LAN setup so it can be sleeping while not in use.
This is great and I appreciate the push to move content over to Peertube. There are a lot of issues with youtube that go beyond just ads. There is a huge moderation problem. For one, there are so many fake DIY videos now. I used to go on there to learn how to do things, but seeing the devolution into ad-supported content that exists soley for the purpose of monetization, spreading completely false information to people is really sad. You can’t trust anything on there. None of it has been vetted by people who know what they are talking about at all and there is no reasonable process for removal of such videos. At least Peertube, you could change instances or if you run an instance you could defederate from bad actors on the platform. Peer Tube is an amazing platform and is incredibly under-utilized.
