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.

I have availability for Rust consulting or coaching. More details soon, and yep my website needs updating. But if you're considering adopting Rust, want your team to use Rust more effectively, or need a drop-in staff engineer, get in touch!

my baggage was somehow not on my flight. Which would be fine, except that I'm flying to LA for a work week at 7am. Wish me luck, all my toiletries were in that suitcase.
