I love Linux, but I can't quit Windows
I've been distro-hopping for probably twenty years. Every time I install Linux I feel a small swell of optimism, like this time it'll stick. Linux never sticks with me.

I'm going back to writing code by hand

Traces Of Humanity
...or welcome back! I’ve been silent for the last 7 years and now I’m trying to resurface with this new blog :-) Some of you might remember my previous work on Qubes OS1, a paranoid-security OS, which I started back in 2009, and led its development for the

Programming Still Sucks
Sorry Peter. — I'm at a birthday party, and while most people here also work in tech, there's always a Guy with a Real Job. You know, a physical job, building some or other thing people need. And this Guy always asks some variant of the same question: aren't you worried AI is taking your job? I glance around and see a…

We see something that works, and then we understand it
“We see something that works, and then we understand it.” (Thomas Dullien) It is a deeper insight than it seems. Young people spend years in school learning the reverse: understanding happens before progress. That is the linear theory of innovation. So Isaac Newton comes up with his three laws of mechanics, and we get…

What I'm Hearing About Cognitive Debt (So Far)
A week ago, I wrote about how Generative and Agentic AI may be amplifying what I’ve been calling cognitive debt: the accumulated gap between a system’s evolving structure and a team’s shared unders...

Good developers learn to program. Most courses teach a language
A bootcamp can teach you the syntax of a language in six weeks. The part that takes a decade is everything else: where the seams go, where the data flows, which decisions you are stuck with for the life of the codebase. This is a senior developer's argument for what learners should actually be looking for, after…

He asked AI to count carbs 27000 times. It couldn't give the same answer twice
Ask ChatGPT to estimate the carbs in your lunch. Now ask it again. And again. Five hundred times. You’d expect the same answer each time. It’s the same photo, the same model, the same question. But you won’t get the same answer. Not even close — and the differences are large enough to cause a

I built my own hair electrolysis machine
Axiom: body hair is cringe. That's how I feel, at least. I decided to build a machine that lets me permanently remove it using electricity.

Maladaptive Frugality
I recently decided to, finally, have my iPhone fixed, only to realize a few hours later that my AppleCare could have covered it. I was in a low mood until my partner suggested that I was robbing myself of a good decision. The iPhone needed fixing, and procrastinating on it wasn’t useful. Deciding to do […]
