AI assisted coding — if you aren’t using AI for software engineering then you’re being swallowed by a whale. You don’t want to be swallowed by a whale. randygaul.github.io/coding/2…

AI Assisted Coding

I recently had an AI implement a brand new lighting algorithm from a 2025 white paper, one-shot, producing visible soft-shadows and constant-time global illumination on the first try. Before that it...

New lighting system is going pretty well - using Holographic Radiance Cascades (arxiv.org/pdf/2505.02041)

A simple C unit test framework

A simple C unit test framework

I wanted to talk a little about my approach to unit testing, and the small framework I've written to help me write and run tests. I am not an expert in unit testing. I don't even give it that much...

Hooked up iq's SDF for polygon rendering. Supports: radial expansion, soft-rendering, self-intersections/overlapping verts. Really easy to render professional looking polys! Limitation: 8 verts max. Perf is really solid as well! iquilezles.org/articles/dist…

A quick and easy way to start making something fun in C. 1. Clone this repo: github.com/mattiasgustavsson… 2. Download tcc and unzip it github.com/mattiasgustavsson… 3. Execute `tcc\tcc source\main.c` You now have window that you can plot pixels in - all you need to get started :)

Hey! A sneak peak of my latest side project: rTextEditor! A simple and easy-to-use text and code editor. Single-binary, multiplatform, 850KB... But the most interesting part: rlte, a single-file header-only text-editor module, portable and usable standalone, pure C. #futureisnow
