How I used linear algebra to build an interactive diagramming editor (medium.com)
Ah, matrices. One of those core linear algebra concepts we all encountered in school. Despite their significance, I never had the chance to work with them during my career, which led me to forget just how powerful and versatile they can be. For me, that moment came while working on Schemio, my interactive diagramming editor. This article dives into how I used matrices to solve some tricky problems, and it’s for everyone who’s curious about the math behind it.

Transforming Colors with Matrices (lisyarus.github.io)
There's one trick we use at work, and now I'm using in my current medieval village building game project, which apparently isn't as well-known as I thought: transforming colors using matrices, interpreting colors as 3D RGB or 4D RGBA vectors. In this article I'll try to explain how it works and which operations on colors can be represented this way.
