Is This a Branch?

Let’s try a new format – “shorts”; small blog posts where I elaborate on ideas that I’d discuss at my twitter, but they either come back over and over, or the short form doesn’t convey all th…

The Perfect Voxel Engine

What is it about voxels that makes people go crazy? Throughout the past decade, there have been SO many developers obsessed with shrinking them down to have as many as possible ( 1 , 2 , 3 , 4 , 5 ), admittedly including myself.

One of these JPEGs is not like the other

“JPEG” or the image encoding specification by the “Joint Photographic Experts Group” (JPEG) is a truly universal format at this stage.

Problems with math rendering on the web (2020)

Since I first started working on my website at age fourteen, the site has gone through many revisions, and hopefully changed for the better. This blog was originally dynamically served using a Python/Flask backend, having a custom login system and post “editor” (just an input box). One of the more strange things about…

After 8 years working and doing side projects in Python and JavaScript (mostly web dev, Django/Flask/AngularJS/Vuejs), I am not satisfied anymore by the overall experience so I’m making Common Lisp my language of choice.I am not here…

Fix Terminals

I want terminal keypresses to Just Work. What do I mean Just Work? I mean programs in a simple orthogonal way, can determine the key that was pressed, and this model should easily map to the user's expectation.
