Today I'm finally launching @stedapp
5 weeks ago I joined @RevenueCat #shipaton late without knowing how to code.
Now Sted is finally live in the App Store 🙌
A place for everything you save: links, articles, vids and more. MVP for now. Goal: make your bookmarks graveyard finally useful.

She's Amazing!
Rails Girls Cali is very thankful for Rails Foundation's support to our event last year!
We have no words to describe how exciting it was to see our team's faces on the Rails World screen this morning.
Thanks to @AmandaBPerino for the trust and our team for the amazing work they've done for @rails.
You can check the Agents on Rails report here: rubyonrails.org/ai

Today is a big day for Herb! It's built into Rails 8.2 by default for all HTML+ERB views.
My talk at #RailsWorld in Austin today answered three questions: What is Herb? What ships in Rails 8.2? And what does this enable?
Herb v0.11 and ReActionView v0.6 released alongside it.

Loved the response from @yukihiro_matz : his new compiler of Ruby into native code, Spinel, consumes 20x less RAM. Perhaps, next time David is gonna choose Ruby again.

Huge thank you to @AmandaBPerino and the @rails Foundation for bringing us on to build the official Ruby on Rails agent benchmarks, and having @palkan_tula and me deliver a report for this work at the Rails at Scale event today: our key conclusions, models failure modes and how you can run lemans yourself are in this deck:

It's pencils down, people. Writing code by hand is no longer an economically viable skill for most programmers at most companies. But the future of making software has never been brighter. Don't you dare black pill this beautiful moment! piped.video/vDjW_dRyKXY?si=6Fsf…

What if your app could fix itself?
You can get your cloud agent to run this loop with EAS Simulator:
GitHub issue → reproduce bug in the sim → detailed bug report → PR with a fix and proof
See it in action with @rami__maalouf’s quick demo
