Your developers aren’t slow
“Why didn’t we ship last week?” As managers, it’s easy for us to blame our team for missing deadlines. But are slow developers really the reason you’re not shipping on time? At Sprintly, we have a lot of data on developer cycle time. We track how long it takes them to complete different types of …

A Thought Experiment: Using the ECS Pattern Outside of Game Engines
It’s been about 6 months since I watched Catherine West’s excellent Using Rust for Game Development sent me down the Entity-Component-System (ECS) rabbit hole, and I thought I’d share some of my findings. I’ve been meaning to write about this for quite a while now but it took a while to put my thoughts into a cohesive…

My experience crafting an interpreter with Rust (2021)
Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but…

Revisiting the Business Card Raytracer
What is the most beautiful piece of code you have ever seen? Not only it is subjective, "beauty" is also a word that can mean a lot of things. If we were to be discussing of raw speed, I would bring up the Fast Inverse Square Root [1] . If we were to judge by aesthetic, my answer would be Andrew Kensler's, 1337 bytes…

Writing a Demoscene Intro for the ZX Spectrum
In the late 80s, I spent an embarrassing number of hours hunched over my ZX Spectrum, typing in Sinclair BASIC programs and rudimentary assembler routines copied from magazines, trying to re-create the Amiga crack intros I’d seen round at a friend’s house. Obviously, they never came even slightly close - but now, many…

Decorator JITs: Python as a DSL
Spend enough time looking at Python programs and packages for machine learning, and you'll notice that the "JIT decorator" pattern is pretty popular. For example, this JAX snippet:
