A software developer and Linux nerd, living in Germany. I’m usually a chill dude but my online persona doesn’t always reflect my true personality. Take what I say with a grain of salt, I usually try to be nice and give good advice, though.

I’m into Free Software, selfhosting, microcontrollers and electronics, freedom, privacy and the usual stuff. And a few select other random things, too.

  • Sure, you’d need a domain name, a certificate, an IP address that’s reachable from the outside, and the RasPi or some other computer.

    If it’s some residential internet connection, you might be able to open up a port and forward that to your RasPi. You’d need to do that in the internet router. Port 80 and 443 are for HTTP(S). (protocol: TCP). Some internet providers don’t allow any of that.

    Your IP address will change with most regular internet providers, so you’d want to buy your domain name somewhere you can change it automatically with a script. Or use DynDNS. duckdns.org would be one of those DynDNS providers.

    If your internet service provider doesn’t allow incoming connections and port forwards, you need to work around that. Use Cloudflare, or better, some better tunnel provider.

    Free certificates for HTTPS are available from letsencrypt.

    And if it turns out Lemmy is too heavy on the Raspberry Pi, try PieFed instead.




  • Thanks. And good call, seems we’re doing similar things. I also had 100 more Free Software apps from F-Droid that sounded useful, or I wanted to try them and never did… These were easy to “clean up”.

    The app for my password manager (pass) isn’t being developed any longer. Guess I have to tackle a few more things.

    Btw, do you happen to know how I’m supposed to move apps which are paired to Bluetooth devices? I got a body weight scale and a fitness tracker, and I’m not sure if I can just copy it to the new phone and it’ll continue to work with the paired device…


  • I did the same thing a few days ago. Just that I switched from an old Pixel with GrapheneOS to the 8a. It’s really come a long way and it’s ridiculously easy to flash GrapheneOS with their “web installer”. Took a few minutes of clicking on the next button. I’m always excited and eager to replace some firmware or operating system with a more free counterpart… But I still need to move a lot of stuff. I decided to clean up and not to move all my mess… Guess it’ll take a few more days until I’m done with that.


  • I think that aligns well with the general advice on how to get somewhere and how to start moving: You take one step at a time…

    And if you’re really down, the only thing that matters is that you do any. And make it a habit to do it regularly. You can worry about the size of the steps and the direction later, after you stopped being completely down and disheartened. But I’m not a psychologist…





  • I once asked a salesman for a different product (not an UPS), why they still use lead acid batteries in their products. He said they’re easier to replace and readily available… I could hook up pretty much any car battery from the shop around the corner to that machine.

    But I’m not sure if I like the failure modes of the traditional UPSes, either. I’ve seen several badly maintained ones in some smaller companies. And on the next power outage, they last like 6 seconds and are practically useless. And I’ve removed one lead acid battery that definitely didn’t look okay any more. Not sure if that’s a fire hazard with that battery type… But there’s that. And I’m comparing 20yo neglected devices which I removed somewhere, to their more modern counterparts with better monitoring, better battery management systems etc.

    I don’t have any valuable insight on LiFePO. Sounds good to me. They generally have some advantages over Lithium Ion. And they’re bound to appear in every other electric car, bicycle, some solar installations in the near future. We might as well put them into our UPSes.

    I’ve also read the recycling process is way more complicated for lithium cells. While it’s easier to recover the lead. And we have a proper infrastructure for that and 99% of the batteries get returned (or something like that). I certainly hope we make some progress with LiIon and LiFePO as well…
