Welcome! You've stumbled upon (or perhaps were pointed to) my public-facing

[_knowledge garden_](https://en.wikipedia.org/wiki/Zettelkasten).

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
|
2025-01-02 03:27:09 -08:00
|
|
|
[[liminalOS-docs]].

## 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
|
2025-01-02 03:33:17 -08:00
|
|
|
with metadata for use with the Obsidian apps.
|
2024-12-29 02:30:48 -08:00
|
|
|
|
|
|
|
|
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.

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:
