Building a new programming language for CAD at zoo.dev. Built a lot of Cloudflare Tunnel. I run austinsystems.org and love reading sci-fi and history.

It's weird that I wound up doing programming languages at Zoo, because I never intended to write one, I barely studied compilers at uni, and I thought I would work on APIs and backend at Zoo. But hey. If you roll up your sleeves and do whatever needs doing, you'll learn a lot.

I can tolerate "lift weights" but you lost me at "read Moby Dick". You should be lifting weights and reading Colleen McCullough's Rome novels.

OK I'm playing Factorio for the first time. Got a decent little smelting column going, and a nice lab row. Next task is to expand the assemblers for all the science pack components, and their intermediate components.

I'm very excited about property-based tests for my constraint solver, it's going to be a really good way to gain confidence. My own little handwritten test cases are good for verifying the basics, but building up a big corpus of property tests will really help. github.com/KittyCAD/ezp...

Add a new test, proptest::square, which generates a square constraint, and tries random values for all its initial guesses. Asserts the system should always be perfectly solvable regardless of gues...

I make my wife coffee every day in this French press that belonged to her grandfather. Today I got some silver polish and gave it a good cleanup. It's so much nicer now.

It's pretty wild how different the accounts of Cixi's reign are in different books or different authors retelling. Jung Chang tells a very different story than Jonathan Spence.

The funny thing is, in 2019, I had printed this out and stuck it to a wall at the Cloudflare Austin office.

`print()` doesn't have a side-effect. that's the entire point of it. don't call that a side-effect, it's just "the effect".

Last week we visited the Pooseum in Richmond, Tasmania, where I was lucky to have a rumor I had heard confirmed. The abundance of flies in rural Australia is a result of the local dung beetles not liking livestock poo. But you can order the right dung beetles en masse from CSIRO to help.

It's on apt. It's literally on Cargo. It's on DockerHub with ads. It's literally on nuget. You can probably find it on snap. Dude it's on portage. It's a Homebrew original. It's on pacman. You can download it on nixpkgs. You can go to pkgsrc and watch it. Log onto the Windows Store right now.

The military service drafted a new policy that classifies them as “potentially divisive.”

Had a great austinsystems.org last night! Joey set up a tiny Cloudflare network to show us how to program NICs. And Sean demoed audio effects in Python (the math behind reverb, vocal harmony, autotune etc). Next month we're doing lightning talks (10 mins or less). Sign up at the link!

Fresh Eyes as a Service: Using LLMs to Test CLI Ergonomics
An LLM's attempts to use your tool approximate what a statistically average user would try. You can use that to automate basic CLI tool UX testing.

LLMs are pretty useful if you're making a new programming language, or a parser for human-readable text. It keeps finding plausible uses of the language, that you'd kinda expect if you just absorbed the general cultural zeitgeist on the internet. It finds edge cases that we really should support.
