I made a 10¢ MCU Talk
I taught a 10¢ CH32V003 RISC‑V MCU to talk. By bit-banging PWM as a DAC and using a tiny 2‑bit ADPCM decoder, I squeezed ~6–7 seconds of recognizable audio into 16 KB of flash. Then I went full ret...

From VS Code to Helix
I want less Big Tech in my life. After years of dismissing Helix as too fringe and complicated, I've tried (and loved) it.

Autodesk's John Walker Explained HP and IBM in 1991 (2015)
One reader of this column in particular has been urging me to abandon for a moment my obsession with IBM and look, instead, at his employer -- Hewlett Packard. HP, he tells me, suffers from all the same problems as IBM while lacking IBM’s depth and resources. And he’s correct: HP is a shadow of

Tips for stroke-surviving software engineers
This is a pretty niche topic; I don't imagine there are many of us out there. Actually, to be strict, I'd say this advice is tailored to people who've had hemorrhagic stroke in the parietal lobe…

Boring is what we wanted
We are coming up on five years since the first M1 Macs shipped. It was an incredible time to be a Mac user. Those first Apple silicon Macs looked like the Intel machines they replaced, but they were better in every single way. In December 2020, John Gruber wrote: We knew this to be true: Computers could run fast and…

Why do some radio towers blink?
One day on my drive home, I saw three towers. One of them had a bunch of blinking white lights, another one had red lights that kind of faded in and out, and the third one, well, it wasn't doing anything. I'm lucky to have a radio engineer for a dad, so Dad: why do some towers blink?

Springs and bounces in native CSS
The “linear()” timing function is a game-changer; it allows us to model physics-based motion right in vanilla CSS! That said, there are some limitations and quirks to be aware of. I’ve been experimenting with this API for a while now, and in this post, I’ll share all of the tips and tricks I’ve learned for using it…

Cancer survival rates are misleading
UPDATE: I submitted a more formal version of this article to the UMAP Journal (Undergraduate Mathematics and Its Applications), which publishes articles that use mathematical modeling for real-world problems, often with a pedagogical or expository angle. A preprint is available on arXiv at…

I've been loving Claude Code on the web
It’s very much a “v1” product. You type a prompt to start a new thread, it launches a little container for your agent to work in, and you can keep talking to it. It produces a branch, which you can open a PR for (that’s the only way to see a diff of the changes Claude Code made, for now). Or if you want to keep…

I built the same app 10 times: Evaluating frameworks for mobile performance
I needed to choose a framework for a mobile-first app at work. I started comparing Next.js, SolidStart, and SvelteKit, then expanded to 10 frameworks. The measurements revealed dramatic differences in bundle sizes, performance, and the real cost of framework choices.

AI can code, but it can't build software

Welcome to hell; please drive carefully
A while back we watched a video on the topic of British road crossings (which I strongly recommend, as well as Chris's shorter video specifically about Zebra crossings ) and since then Tess has been calling out the different crossings by their proper animal names. This explains why, with tickets to a Halloween event…
