Welcome! You've stumbled upon (or perhaps were pointed to) my public-facing
[_knowledge garden_](https://en.wikipedia.org/wiki/Zettelkasten). garden_.

This is where I grow my ideas, and they are meticulously tagged to form the
knowledge graphs you see in the top right.

Currently this is a very new vault and there are not many contents. It will
likely be updated with notes on courses in mathematics and computer science as
well as other expository content.

In addition, many of my experiments and hacks will be documented here for
posterity.

If you're interested in the Nix package manager, I've started maintaining a
sort of "cheat sheet" or "tips and tricks" collection around various quirks and
features of the NixOS / nixpkgs ecosystem in [[nixos-cheat-sheet]]. Maybe
you'll find something useful in there!

Also, there is some documentation on the
[liminalOS](https://github.com/youwen5/liminalOS) system distribution in
[[liminalos-docs]].

Feel free to take a look around and appreciate the scenery!

## FAQ

> How do you edit these notes?

The underlying notes are simply Markdown files. Precisely, they are
[Obsidian](https://obsidian.md/) compatible Markdown files, which are tagged
with metadata for use the Obsidian apps.

However, I do not use the Obsidian desktop app, for two reasons:

1. Out of principle, Obsidian is [free as in free beer, but not free as in free
   speech](https://www.gnu.org/philosophy/free-sw.en.html).
2. (main reason) [Vim](https://neovim.io/) is just too good to give up.

Therefore, I edit my notes using the free and open source
[obsidian.nvim](https://github.com/epwalsh/obsidian.nvim) plugin for Neovim.

> I want to know cool technical details about the site!

Glad you asked, real person who is interested! This site is powered by [Quartz
4](https://quartz.jzhao.xyz/), and uses `typst` for math typesetting, not the
common `LaTeX`. Behold:

integral _(diff Omega) omega = integral _Omega dif omega
