Bird brains (2023)
A kea parrot in New Zealand learned to drag traffic cones onto a highway so cars would stop and humans would feed it. That sent me down a rabbit hole on how we actually measure bird intelligence.

Insects don't swarm at LED lights
Remember when you used to encounter swarms of insects around outdoor electric lights? Their well known attraction to outdoor lights is used by entomologists and moth lovers to conduct insect surveys. All you need is a light and a white sheet to see who’s flying at night.

The paper computer
Now that we have actually good AI, I have this vision of a form of computing that doesn’t involve me using a computer so much. Imagine you had the day’s emails to go through. It would be nice if the ones that required a simple decision could be dispatched with a few pen-strokes: I could write down a date that would…

I'm scared about biological computing
I’ve been in the AI space since ChatGPT first dropped. I’ve toyed around with a lot of Language Models, built random side projects, built a couple from scratch and I’ve spent hours looking at the math behind it all.

Aluminum foil (2021)
It’s typically 10 μm thick and 400 mm wide, giving it an aspect ratio of 40000 in that dimension, and rolls are commonly some ten meters in length, for an aspect ratio of 1 000 000; heavy-duty versions can reach 30 μm or more. Despite their thinness, foils of 25 μm or more are impermeable to oxygen, water, and light…
