Linux

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.

I was also thinking of running a Minecraft server on it. (Being able to play on the same world from different devices is kinda cool.)

The latest versions won't work. It has problems loading the chunks.

Source: Tried it myself

You can run an (emulated) IBM mainframe on it!

Skimmed the title. Brain registered words "rpi" and "linux" underneath it. Instant reaction: "Not another app package format please". 😶‍🌫️

I should spend more time reading properly & less time being an old man yelling at tech.

Joplin notes. A really nice notetaking app you can selfhost. Simple enough but stil verry advanced.

irks me that it’s mostly idling

Well it's a small processor and relatively efficient one at that so... how about going the opposite direction? How about measuring the power draw on idle? With other task? I don't actually know if that architecture handles that but I saw some things on the do https://developer.arm.com/documentation/100095/0002/functional-description/power-management/dynamic-power-management?lang=en

Also what about using a RPi Zero instead?

mine is my reverse proxy, using the nginx proxy manager docker install method

As a general thing because I found myself trying to justify my Gear Acquisition Syndrome -- it's a good idea to split services across devices, rather than having some monolithic home server (which is where most people start). That way if one box goes down, it doesn't take down your whole stack.

If you have some machines scattered about doing different things, it might be time to consider logically grouping services and splitting them across that hardware.

I run a asterisk PJSIP VOIP server on my raspberry pi 5 8GB. I had to use the git and build and recompile and manually load all PJSIP modules because for some reason I couldn't even find an asterisk package on apt db for ARM64 for some fucking reason. Also had to containerize it within a docker because the shit couldn't properly compile without interfering with native system binaries. Shit is so fucking goated and can do PSTN via twilio trunking (call numbers outside of the phone server's number base so basically anyone as long as you make the phone numbers parsed in extensions.conf for each country you wanna call XD). Currently works within LAN but I am planning on making it accessible over the internet using my domain and a tunnel for UDP if possible or just a VPN since my router is being a removed with SIP packets rn. I am having trouble with that part but once it's done I can quite literally ditch any phone plan and use it. Twilio hardly even charges shit for voice rates 🤣🤣🤣. You could also self host your domain + email providing service and then connect that to thunderbird for full schizo-level privacy or sum shit. That's what I do to ditch web-email BS
