SDL is at the application layer though. Each individual game has to support it.

As absurd as it might seem, the Steam Controller is technically not compatible with Linux.

What I mean by this: officially, it only works with Steam Input, which only works for Games you launch from Steam. It is not fully recognized and supported by Linux yet, and perhaps it never will.

Assuming you are not in a CGNAT, which is common for mobile networks: DNS with low TTL such as FreeDNS, pointing to your IP. And ofc, if you have a router in between, port-forwarding.

Otherwise, a VPN such as Tailscale. But you would need to install it on all your devices.

Otherwise, for HTTP(S) web services, a reverse-proxy such as CloudFlare.

(Personal opinion not based on scientific evidence.)

I would say that’s not possible for a hobbyist. The main issues with this kind of DIY phones are performance, compatibility with existing software, and most importantly battery life.

The Raspberry Pi was never designed to be used with a small battery while still staying connected to the internet to receive notifications all the time, like a smartphone. If you want to build a usable smartphone you will need an efficient co-processor to do these tasks. This could get complicated fast unless you use a CPU designed for this job.

There has been some interesting progress with desktop environments and small touch screens. Still nothing as good as Android, but nice UI is no longer the main issue imho.

As for compatibility, good luck running Signal, Matrix and Thunderbird in the background without draining the battery.

That being said, if you are just doing it as an excercise without expecting to build a device that will replace your main phone, you can definitely give it a try. Have fun and learn much!

Ah! Sorry for the textdump, and thanks for the feedback. I’ll keep it in mind in the future.

Sorry, not an answer to your exact question… Dockge might be the answer if you need a web UI to manage Docker containers.

If you need something more specific, like a button dashboard to run custom commands, perhaps you could build your own with Vite (Node.js). You will need to understand basic HTML, CSS and JavaScript. (EDIT: OliveTin makes more sense.)

As for authentication, you could configure a basic authentication on your favourite reverse proxy (such as Nginx), or look for something more advanced such as OIDC/OAuth2 through Keycloak.

In that case I would say start with a Debian-based or Ubuntu-based distro of your choice. Ubuntu-based distros are also Debian-based, since Ubuntu is Debian-based. Mint is Ubuntu-based so it’s a good choice imho. Mint should work pretty well for backups and Minecraft.

As a counter-example, Mint would (probably) be a poor choice if you want to turn that PC into a router or a DNS server, but sounds like that’s not what you have in mind.

If you plan to Install more stuff in the near future, you could optionally look into containerization (Docker) which would allow you to someday swap Mint with another distro when you decide that you feel like changing. All of this, without having to reconfigure anything. Portainer might be a good soft-entry to Docker if you don’t love the terminal, it gives you a nice UI. And it’s compatible with Mint, ofc.

As for the fedi instance, it’s a good exercise, you will learn a lot about networks. Personally I tried installing a Lemmy instance too, but I ended up turning it off as I realized that it didn’t make sense for my use case. It just wasted bandwidth to stay in-sync with the rest of the fediverse.

It depends. What do you plan to use it for? Depending on the answer, perhaps Mint might not be the best option, but I can share my personal experience.

My use case is a headless server running OCI containers through rootless Podman (this is Docker’s modern equivalent). I’ve been running this on Linux Mint on a compact PC for a few years. I enabled unattended upgrades, and once in a while I VNC into it and upgrade Mint itself. I also installed a CRON job to reboot automatically every few days. So far I’ve not encountered any major issues.
