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.

You could always have Graphene over WiFi as your main phone and then have a dumb phone you take in the car with you for emergencies. I had a cellphone running Graphene and it died and I just got a dumb phone and I went back to using my computer for everything else now. It’s mostly a better workflow for me. I think the main way it becomes problematic is most jobs require you to have a smart phone so they can do payroll and tracking you through apps. I really don’t want that and I have been fortunate enough that I have been getting enough work independently now that I can decide what I do and don’t need in that regard. If that is your situation, you could always keep the I-phone for shit like that and have a place to put it when you are done with work… So you can disengage with the phone once you are not working. Then get a Graphene phone for your leisure time. There doesn’t have to be set rules that you can only do one thing or the other.
