Hilbert space: Treating functions as vectors
The tools of linear algebra are extremely useful when working in Euclidean space (e.g. \mathbb{R}^3 ). Wouldn’t it be great if we could apply these tools to additional mathematical constructs, such as functions and sequences? Hilbert space allows us to do exactly this - apply linear algebra to functions.

The Geometry Behind Normal Maps
Tangent space is often presented as a confusing block of shader math. This is a deep dive into what tangent vectors actually mean, how they emerge from UVs to bridge 2D and 3D space, and the geometry that makes normal mapping possible.

A catalog of side effects
Optimizing compilers like to keep track of each IR instruction’s effects. An instruction’s effects vary wildly from having no effects at all, to writing a specific variable, to completely unknown (writing all state).

Advent of Code on the Z-Machine
Fantasy consoles like the Pico-8 are a great idea. A fantasy console provides a standardised and portable environment in which developers can explore ideas within creative constraints. The Z-machine , developed by Infocom in 1979, is the earliest fantasy console I know, although this is probably the first time it’s…

The lazy Git UI you didn't know you need
When my son was born last April, I had ambitious learning plans for the upcoming 5w paternity leave. As you can imagine, with two kids, life quickly verified this plan 🙃. I did eventually start some projects. One of the goals (sounding rebellious in the current AI hype cycle) was to learn and use neovim for coding. As…

Think in math, write in code (2019)
Programmers love to discuss programming languages. We not only debate their technical merits and aesthetic qualities, but they become integrated into our personal identities, along with the values and traits that we associate with them. Some even defend a form of Linguistic Determinism that thinking is confined to…
