GitHub - openai/harmony: Renderer for the harmony response format to be used with gpt-oss Renderer for the harmony response format to be used with gpt-oss - openai/harmony

🚨 OpenAI just open-sourced Harmony — a renderer for the Harmony response format used with gpt-oss.

And guess what it’s written in?

🦀 Rust, of course.

Oxidizing Fedora 🦀 Today’s Issue: Rust’s Stealing Hearts Again As the Most Adored Language, Sudo-Rs Headed to Ubuntu, and the Scary and Surprisingly Deep Rabbit Hole of Rust’s Temporaries

This project spotlight is part of our weekly newsletter below 👇

Jujutsu is open-source on GitHub at github.com/jj-vcs/jj, and they got a cute logo too.

- Conflict resolution magic - Conflicts are first-class citizens, stored in commits and auto-propagated, making rebasing a breeze.

- Operation log & undo - Made a mistake? jj tracks every move, so you can rewind like it’s a bad ’90s rom-com.

- Working copy as a commit - Every change is a commit, auto-saved and amendable. No stashing nonsense - your work’s always ready to roll.

- Git compatibility - It works seamlessly with your Git repos and tools. Push, pull, and switch back to Git without breaking a sweat.

It’s built to handle concurrent operations without corrupting your repo, so you can sync to Dropbox or S3 without praying to the tech gods.

Why jj is awesome:

Git’s great, but it’s also a clunky beast, staging areas, stashes, and cryptic errors that scream “your local changes are doomed!” jj tackles these by streamlining workflows, ditching the index, and making history rewriting as easy as deleting a bad tweet.

Born from a hobby project by Martin von Zweigbergk (at Google) in 2019, jj has grown into a slick, Git-compatible VCS that’s all about simplicity and power.

It’s like Git, but with a personality that doesn’t make you want to pull your hair out.

This Week's Project Spotlight 🦀

Jujutsu (jj) is the Version Control System (VCS) that will make your Git life less of a headache.
