Hand Tracking for Mouse Input (2023)
The other day I saw the launch of Apple Vision Pro, the whole thing was very interesting, but one thing that caught my attention was the finger input. It seems very intuitive, by using the finger pinching as sort of like a cursor or mouse input. I figured I want to try it out, so I took it upon myself to create it.

A love letter to bicycle maintenance and repair
It was the 28th of June, 2020; the perfect summer day. I remember it distinctly because of two important events that took place on that day.

Let's create a Tree-sitter grammar
One of my favorite features in Neovim is the Tree-sitter integration. It allows for fast syntax highlighting that works well even in an error state (often the case when you’re editing code), and it has additional semantics (you can differentiate between function parameters and local variables).

Deep Bug
The project has been haunted by a mysterious bug since sometime February. It relates to the code that constructs the index, particularly the code that merges partial indices.
