This is FUD. It definitely is not a “critical” security feature. Firefox flatpak can’t currently do its own internal sandboxing of subprocesses via namespaces, but it does do seccomp bpf filtering. That’s in addition to the standard sandboxing of flatpak itself, which is implemented using namespaces anyways.
If you are extra paranoid, you can tweak the flatpak’s permissions to harden the sandboxing via your distro’s flatpak settings app.
Flatpaks are containerized, making them both more reliable and more secure (in general… but it’s always possible to fuck things up).
Besides the benefits to users, there are also huge benefits to developers: they can publish a single package and support nearly every distro with it.
It’s often impossible for a dev to publish and maintain packages for all Linux distros out there, so stuff on AUR is built and packaged by well-meaning, but random people who are not the original developer. This very often leads to the app having bugs and compatibility issues which the developer ends up wasting time debugging and trying to fix even though it’s not their fault. (although downstream packagers can fuck this up too by publishing their own unofficial Flatpaks, like Fedora’s recent OBS shenanigans)
I tend to go with Flathub before the AUR, if available.
This is the correct way to Linux in 2025
I actually love the name “techno mechanicus”. The others are just weird, but I find that one laugh out loud hilarious.
I used to think like that, but now I’m on the fence since I’ve started working much more closely with packaging. Calling it “linux” is actually kind of harmful for adoption. Devs that claim their software works on Linux mislead people into thinking it works on any Linux distro, which is rarely true. Most of the time, those devs only test on Ubuntu and no other distro.
Maybe when Snaps finally die out and Flatpak emerges as the one true standard for desktop apps, then that problem will go away once and for all. Until then, I think we should normalize distinguishing Ubuntu, Fedora, Arch, etc as separate “operating systems” instead of “distros”, which is an unnecessary and misleading term anyways.
I was going to comment that this looks more like ffxiv than skyrim, and expose the boomer who made this meme that can’t tell the difference between two extremely popular games.
Although I’ve never played ffxiv so I don’t actually know if that’s what this is, and I didn’t play enough skyrim to be able to identify those wall/ground textures.
