Ghostty is leaving GitHub. I'm GitHub user 1299, joined Feb 2008. I've visited GitHub almost every single day for over 18 years. It's never been a question for me where I'd put my projects: always GitHub. I'm super sad to say this, but its time to go. mitchellh.com/writing/ghostt…
I wanted JavaScript documentation without paragraphs of bla-bla, like in Turbo Pascal/Delphi. Made this manually before LLMs, now published online.

🚨 Introducing ThreePointTwo: Utility-first attributes for the World Wide Web to rapidly build modern websites. @tailwindcss showed us how easy it is to create when you don't have to think about CSS. ThreePointTwo takes this to the next level: now you don't have to write classes
Just tried for various text tasks: not bad for 350M! Follows instructions almost perfectly. Very nice for its weight category.

The greatest thing is that you don't have to install anything! Link ----> dchest.github.io/threepointtwo/
