NixOS is a Linux distro that does a lot of things differently (for the greater good), and gaming is heavily Windows thing, which is hard to do even on conventional Linux distros (its getting better tho). That said as for your points:

1a. One of the things that would help you, is programs.nix-ld.enable = true; (for more info check https://github.com/Mic92/nix-ld , but its integrated in NixOS already)

1b. UE5 pull request has some things that might help (eg: you could just try running it with steam-run): https://github.com/NixOS/nixpkgs/issues/124963

2. Depends how you are building them, I am not a gaming developer nor tried to build a game without packaging it with Nix. But if you manage to run the UE5 I guess the procedure would be the same as long as you have all of the dependencies available for UE5

3. I am using qemu/KVM on NixOS to run games on with quite a good performance, so that should not be a problem

Thank you, integration with activitypub is what i was after!

Stop making a list and start with eg: Nix Pills

Dont know where you are getting this. Nixpkgs is a breeze to manage compared to apt repo. Also it does not matter if you are on nixos or non-nixos system, the only difference is that nix does not take care of services on its own. What kind of docs do you miss? Nix has its own extensive nix docs page, and for packaging you also have nixpkgs documentation page - also official and not much related to nixos itself. Also nix has quite good man pages.

I knew that takos have a lot of output energy, but I did not knew that takos can power a whole car!

(I wish that someone would already posted something like this so I could just upvote it.)

I am not particularly good at math myself, but I like to program stuff… If I am any good at it… decide for yourself: https://github.com/matejc?tab=repositories … anyway, if you have interest of doing something, stop the doubt, just do it.

Looks intriguing, reading a bit … some concepts look like they came from Nix

In i3wm/swaywm, hyprland, … You can assign workspaces to outputs (monitors)

Depends, does your CPU has already one?

Yes, if you run a non optimized VM everything will be slow. It took me few weeks at start to discover all optimisation options for qemu/kvm and then years of perfecting it to make it run very close to bare metal

Edit: the key is to pass through one of your graphic cards

Zsh and Starship.rs on top with few extra minor things. I like my shell fast and clean.

All those points assume that you would have compatible apps for both platforms. For some small subset of applications might work… Like VLC player, Firefox, Chromium browsers, … You could try to run Windows apps with Wine, but that can be done on app basis and will not be generic

What do you mean, what do you think is so special about Photoshop? I play Starfield on Ultra on Windows inside Qemu/KVM virtual machine on Linux.

I used to have Silverblue for my work laptop OS, I broke it quite fast, multiple times, got annoyed, switched to NixOS like on my home setup. I am the person that tinkers with everything, and NixOS just wont die. I need to install it only once per computer’s drive lifetime.

Is it still necessary to reboot if you install/update/remove some system package?

How about jitsi? https://github.com/jitsi/docker-jitsi-meet I am running it for years, works much better than Facebook Messenger that is for sure 😃 not sure what you mean about the “all the standards”

Huh, 2cm in height… I have twice as much height there and it was very difficult and time consuming to remove supports, also the figurines are very fragile, I can imagine that 2cm figurines would be even more difficult. If you have two nozzles on the printer you could use the second to print water soluble support material

I have made some figurines 4-5cm in height, with some random PLA, maybe it can serve as example for you… Btw, what do you mean by 1:72?

What are you talking about? What nonfree programs? Can you give an example? Btw, for VPS you normally just need ssh, and that is free and even OSS.

Both have issues, just that X11 has old issues that rarely someone is workin on, while Wayland has new ones and people are fixing them. So Wayland for me, thank you.
