The Lamentable Later Life of Lemmings
For a while there in the early 1990s, there seemed to be good reason to believe that Lemmings was on its way to becoming one of gaming’s perennial franchises. Developed by DMA Design of Dundee, Scotland, the original Lemmings game took the world by storm upon its release in 1991. From its first home on the Commodore…

What Zig felt like, coming from Rust
What Zig felt like, coming from Rust Intro I’ve spent the last 7 years as a Rust developer, working mostly on open source projects, and I’d like to think I’ve built a solid feel for the language and its ecosystem along the way. I gravitate toward the functional side of Rust like clean functions, expressive types, that…

Science Is Open Software
TL;DR I claim that modern science is synonymous with open source software. This post explains why, why it matters, and what you can (and should) do next. Why do you care about (open source) software? - Everyone I spend a lot of my time working on software. I have been asked why software matters more times than I can…

How did AMD Ryzen get 50% faster in two years?
People still tell me that CPUs are boring. That nothing much happens anymore. Let us look at AMD Ryzen 7 processors from 2022 to 2024: the 5800X3D (Zen 3), the 7800X3D (Zen 4) and the 9800X3D (Zen 5). They are comparable 8-core chips with 3D V-Cache. I have written about them before, in How stagnant … Continue reading…

Saving another 100TB of RAM
Cloudflare's global network is immense but not limitless. As we look for small ways to trim our resource usage, we sometimes get lucky and we can cut significantly more. Here’s how we reduced one of our Pingora-based service's RAM usage with statistics.

In early 2025, I started seeing people turn off their brain as they use LLMs 1 . They would have an LLM take an action (summarize text, write some code, etc.), and just assume that it worked 2 . This generally didn't work in early 2025 and the result was often quite silly.

A custom virtual machine for the Stars 4X game
Stars! is a 1995 4X game (explore, expand, exploit, exterminate) for 16-bit Windows 3.1 that I first played ~28 years ago. While Windows is famously backwards compatible, it’s notoriously difficult to play Stars! today. Windows x64 cannot run 16-bit applications, and playing requires either retro hardware or emulation…

Bend 2 and the Vibe-Coding Trap
Bend just serves as a useful example of my general point regarding vibe-coding as it is recent, high-profile, and has aspects that make it easy to use as an example. I don’t know anything about the author’s history with designing languages or if they actually did consider the tradeoffs below and made what I think is a…
