* 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 want to be in the process of moving all of my systems to Guix. However, Guix is still missing quite a few things that I think I'll need. Like for example, hyprland works, but eww doesn't. Also, firefox doesn't seem to work with tridactyl's native messenger. I did build it myself and get it working, but that's it. Finally, I can't seem to figure out how to get my rust project working well there so I'll keep Nix for that.


* 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.

*** hardware
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, ... }:

** 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!
