$ systemd-run --user --scope -p MemoryMax=4G cargo nextest run woops
is preetty cool. I thought I'd have to mess with docker or something.

just for fun, with apptron you can jump into linux in the browser, boot up stock apache, get a public endpoint, and browse to the default page... served from the apache running in the other tab!

Sometimes I look at the code suggested by Copilot and think of the developer who originally wrote it.

I've just realised that reading more fiction books for fun has really helped with me being able to focus properly on reading other stuff.
I was just reading something that usually I would skim.
Instead I noticed I was taking time to understand it, sometimes, re-reading sentences.

Durable Executions, defined
Every durable execution framework: write normal code, get fault tolerance. Yet nobody defines what normal code or fault tolerance are
The alternative: a rigorous definition, grounded in first principles, and a minimal implementation

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?
It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

The positive thing about AI tooling going mainstream and setting expectations high (e.g. "anyone can build software with AI") is that a large group will learn what us devs know already:
Creating good software is hard and it's hard to explain to outsiders in a way they understand

📰 LLMs are mirrors of operator skill
LLMs are mirrors of operator skill
This is a follow-up from my previous blog post: deliberate, intentional play. I didn't want to get into the distinction between skilled and unskilled work because people take offence to it, but AI is a matter of skill.
Someone can be highly experienced as a software engineer in 2024, but that does not mean they're skilled as a software engineer in 2025, now that AI is here.
In my view, LLMs are essentially mirrors. They mirror the skill of the operator.
