Our second Austin Systems went very well last night! 18 people showed up. Pizza sponsored by a local tech company, most people stuck around for beer at a local bar. I asked one guy how he heard about the meetup: "I just googled 'austin systems programming meetups'". Perfect.

When you say "the sky is blue," you're making such an obviously wrong statement -- we all experience sunsets, night skies, some of us have seen sandstorms or fires turn the sky orange -- it's clear you're misrepresenting the facts and aren't trying to have an honest good faith conversation.

Helix (my favorite text editor) just added full KCL support! I'm very happy -- this is the first project outside Zoo to support KCL.

i have been negatively polarized into pro-lead consumption. the anti-lead consumption people shouldn't have been so rude to me.

Before you embark on a journey of revenge, dig two graves. One for practice and the other one is the "main" grave.

Austin Systems in on this Wednesday (Oct 15). I'll be walking through a 2D constraint solver, and @steveklabnik.com will be talking about compiler internals for a compiler he's exploring. Very excited! austinsystems.org has the details.

Austin Systems Programming

A meetup for curious low-level engineers in Austin, TX. We meet in-person monthly.

to clarify, I wasn't referring to you, just thinking about the many killjoys I know

chronic hating is a personality, it's just a very boring and unpleasant one

Madeline is one of our favorite books to read to baby. It's got such beautiful art and text.

i would simply not add the plastic where the hole goes

3D printed the holes, straight from KCL

Yep!

You can use the zoo CLI to render KCL to an image, and display the image in the terminal, and use filesystem watchers to both rerun the CLI and refresh the image whenever the source changes :) I do this sometimes for working on KCL.

Had a really good day at Zoo's annual all-hands. Mitchell Hashimoto visited our office to speak about some startup advice/stories and stuck around to field all our questions about Ghostty and terminals. Then we did some usability studies. Finally went to the incredible Griffith Observatory. Fun day!

This is the first release since I started contributing! A lot of my changes, like tests, fuzzing, benchmarks, nushell support, Intel Mac support and parsing the new download format for 3.3.x, are now released. It's been fun working on a new open source Rust tool.
