What’s really amazing about vibe-coding is how people are replacing programming languages which are strictly deterministic with human speech which is highly ambiguous and expect programming to be faster and better.

Exactly! Why?
I became a software engineer because writing code is fun. Thinking through hard problems, designing elegant solutions, seeing the things you’ve built working for the first time… these moments are all deeply satisfying, so why in the world would I ever surrender them to AI?

Rails has given me a lot, and giving back through open source has always felt like the natural response. Looking forward to continuing the work. ❤️

Obviously this is a beta release (written off of RC2), but there will be a second beta right on the heels of the release next week.

I believe that a Ruby Renaissance is underway, and even if collaboration with others has become more challenging with a fragmented ecosystem, it doesn’t have to be that way.

I enjoyed listening to this episode yesterday and learning more about why all the fuzz about jj.
Clean, review-friendly history shouldn’t require five different rituals and incantations. Steve Klabnik breaks down how jj makes common Git workflows feel simpler and more natural.

"SF Ruby was a technical statement. We’re fighting skepticism with running code. We’re bringing Ruby-powered startups into production at scale. We’re building the tools the ecosystem needs."
“The promise of Rails is being fulfilled. People just haven’t caught up with this reality yet,” says @inazarova.bsky.social.
We wrote about SF Ruby and reveal the real reason we decided to host the conference.
