actually… it’s pronounced ped-antic, not pee-dantic

one good measure of a city is how frequently strangers will (positively) interact with your baby and/or let you pet their dog. SF is demolishing NYC here.

Sorry, I prematurely abstracted. This doesn’t usually happen.

premature concretization is the root of some evil

github.com/kitlangton/s... a thing

I've been working on a lil' GitHub TUI. github.com/kitlangton/g...

If you're mortal, you're ngmi.

Oh yeah. I've been adding some animations to the opencode desktop app.

Some news...

Unnecessarily, I converted the effect.institute Effect visualizations to WebGPU.

It is time → effect.institute. 2026, the year of 𝚎𝚏𝚏𝚎𝚌𝚝. I'm extremely proud of how this turned out. There are many chapters to add, but I do hope you enjoy what's there so far. Let me know what you think. 🫡

www.effect.institute is the coolest course I ever took. Big props to the @effect-ts.bsky.social team for that level of creativity!

Sync vs. Succeed

Failure.

Working on some weird Effect lessons. Waiting list → effect.institute

Real TypeScript has never been tried.

A nascent effect course.

Creepy recommendation: Make an ElevenLabs voice clone of yourself and then use it to read articles to yourself with their Eleven Reader app. It's sort of like you're hearing yourself think, except you're verbatim thinking other people's blog posts.

@emmabyte.de just knocked out all of the issues that @fasterthanli.me opened in the Hex repo in about half an hour—having never used Swift before! Thank you, Emma! 🎷🐓 github.com/kitlangton/Hex

Hex is now open source! 🫡 github.com/kitlangton/Hex

I just open-sourced my meditation app, Void. It uses SwiftUI and @pointfree.co's beautiful Composable Architecture. Check it out; learn something; realize I've made a design decision differently that you would have; publicly shame me! 🪷

Hex from @kitlangton.bsky.social just became my new go-to voice-to-text software on Mac. What a wonderful little GUI for OpenAI's Whisper models. Does one thing and does it perfectly. Kit says he's open sourcing it soon, too! hex.kitlangton.com

I just released a free Whisper wrapper. 🙇‍♂️ To be open sourced sometime in the next week. hex.kitlangton.com
