My Nix system configs! (by malob)

Project mention: NixOS-generators – Collection of VM and Container disk image builders for NixOS | news.ycombinator.com | 2024-03-26

I’ve found it most helpful to review other people’s configurations to learn Nix.
Some specific ones I really like:
https://github.com/malob/nixpkgs
https://github.com/fufexan/dotfiles
I keep a not comprehensive GitHub Stars list of Nix stuff I find here if you want more:

If you aren’t familiar, Nix-Darwin allows you to codify your MacOS deployments in a fashion comparable to NixOS. As a huge Nix-Darwin user myself, I have found malob’s repo extremely helpful for ideas with MacOS configuration. Nix-Darwin has made me so happy as a MacOS user. :)
Some other unsolicited tips:
1. Start with Nix flakes for configuration
2. Invest in Home-Manager before NixOS or Nix-Darwin
3. Ask people for help in Matrix or Discourse — my experience is that Nix-related folk are very welcoming and understanding
Good luck!

Project mention: $Home, Not So Sweet $Home | news.ycombinator.com | 2023-08-16

For games, I think it's even worse on GNU/Linux systems, since most game developers mainly target Windows and sometimes completely ignore conventions for other platforms (possibly since some game engines have that "Build for Linux" button).
This also applies to game engines and their own conventions. For example Unity has Application::persistentDataPath[1], which uses $XDG_CONFIG_HOME (still a bit meh, since I wouldn't treat savefiles as "config", but at least some convention). However, some games tend to write those into Application::dataPath[1] (or even other random directories they see fit), which is supposed to be read-only and could possibly be outside of $HOME.
Fortunately the single one advantage of antivirus software out there seems to be that the above seems to break with some AV, so developers either tell their players to disable AV or they simply fix the issue. I made countless bug reports on this issue and so far it exclusively got fixed because of AV, so I'm using that as an argument for future reports.
While at least most of the Unity games I've packaged seem to adhere to these conventions, other games and game engines are a mixed bag and I've seen games dumping their stuff into $PWD to games writing to Windows paths (eg. /home/foo/SomeVendor\Somegame).
Patching these games is also very tedious, since some of them tend to get updates, so patching needs to be done in a way to be forward-compatible.
For example here is a patcher I wrote to get Factorio to adhere to XDG:

Here is an example for patching a Unity3d game that writes to Application::dataPath:
