If you(they) don’t mind having outdated software Debian stable might be worth looking into. Otherwise there are immutable distros which are very hard to fuck up, and even if you do there is the option to rollback to the previous version. I’d recommend Aurora or Fedora (fedora doesn’t include some proprietary stuff like some codecs so if you need that it’s probably better to use Aurora).

Linux Mint also has a version based on Debian stable, LMDE, which is could also be an option. It’s not as stable as Debian as it adds its own stuff but has the out of the box experience.

As general advice I’d suggest using less packages and more flatpaks as a faulty flatpak update can only break that flatpak, not your system. For packages be sure to disable online updates, meaning you have to reboot to apply them. This isn’t as convenient but if stability is that important to you I’d go for it

Okay so first there was Unix. It was semi Open Source and a bunch of companies were making different versions that were becoming increasingly incompatible. That is why POSIX was created, it standardizes major parts of Unix. Linux is a Unix like operating system, meaning it functions similarly but doesn’t share any code. One thing that POSIX standardizes is the shell meaning there’s a standard how a loop works etc. Most shell on Linux like bash and zsh are POSIX compliant but some (like fish aren’t). This means a command that works one way in bash might work differently in fish. Basic stuff is mostly the same in my experience so if you’re not having any problems you shouldn’t worry about being POSIX compliant. If you want most of the same stuff but POSIX compliant checkout zsh. Fish provides documentation for adjusting your commands so I’d just ignore it until you run into a problem and then take a look at the docks

As far as I’m aware Photopea is supposed to fill the same niche as GIMP or Photoshop, though I’m no expert in the field.

Have you tried Photopea? It’s browser based but very good

With WinApps you do the bulk of the setup manually, and there’s no cohesive interface to bring it all together. There’s a basic TUI, a taskbar widget, and some CLI commands for you to play with.

WinBoat does all the setup once you have the pre-requisites installed, displays everything worth seeing in a neat interface for you, and acts like a complete experience. No need to mess with configuration files, no need to memorize a dozen CLI commands, it just works.

Why Chatgpt and not Gemini? Also why no vpn? You could have put VPN by Google

We have Wine / Proton of course and they can run a lot, but not everything is possible. WinBoat is different. Instead of running compatibility layers, it runs a real copy of Windows using Docker and KVM under the hood. The developer explains it should run basically everything unless “it requires strong GPU acceleration or kernel-level anticheat”. It uses FreeRDP for showing the apps on your Linux desktop, enabling you to interact with them like you would with any other Linux app.

I don’t want to sound rude, but maybe read the article and not just the headline before asking questions

If you want DNS filters you can use Mullvad DNS which is free, privat, doesn’t require a app and can be used together with uBlock lite

The only Desktop one that comes to mind is Interstellar, but you could probably also use a web fronted that is instance independent like phtn.app (Which I would recommend if it works)
