Welcome

This repository contains all of my dotfiles to the many programs I like to use on Linux. This is primarily built with NixOS. I have organized this with flakes and modules.

Guix

I am in the process of moving all of my systems to Guix. I'll keep NixOS as a system for most servers probably but for desktop systems, I think I'll start using Guix since I enjoy lisps a lot.

NixOS

The flake points to the correct machine which starts in the system directory. Then it uses the appropriate modules that the machine needs.

Syl

Syl is my laptop and has some configuration unique to that. In particular, it's a Framework Laptop. Honestly a great piece of tech. Love it.

Notice how I am including all of my software here. It may be a big file, but having all of it in one place means I can easily grok through it and remove something.

Hardware

Now in the hardware-configuration.nix file, I didn't change much because I wanted to keep it roughly the same in case things do get overwritten, but this is another nice feature of literate programming, should things change in the /etc folder, I'll have this readme as a backup of what it was before the changes.

}

Kaladin

Kaladin is my desktop machine. A powerhouse for the most part with a recent i7 and 64gb of memory and an Nvidia 1080. Basically I use this for video editing, animation, and some other things. Here is it's configuration.

And here is it's hardware config.

Kaladin is still not fullly setup, so I'll be working on that more and more as time goes.

Dalinar

Dalinar is my home server. It's built with an old laptop at the moment, but the way everything is orchestrated is to protect from screw ups.

Containers

Here are Dalinar's containers

First off, I'm not entirely sure how this works, but this is my best guess.

jellyfin = {
  config = { config, pkgs, ... }:
  {
    # ...
  };
};

Hardware Configuration

Dalinar's hardware

# and may be overwritten by future invocations.  Please make changes
# to /etc/nixos/configuration.nix instead.

Kohlin

Kohlin is another home server. It's built with an old laptop at the moment, but the way everything is orchestrated is to protect from screw ups.

Home

I also use home-manager for managing dotfiles. This means that everything is contained in this folder and then tangled out to their respective places when rebuilding the system.

Thanks!
