Marco Roth

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.

Opened a PR so Herb can be aware of Rails Icons. ❤️ https://github.com/Rails-Designer/rails_icons/pull/117

A group of top-tier Rails developers I know and worked with (plus myself) were unfortunately laid off today. Any company would be fortunate to pick them up. If you or anyone you know is hiring, send me a DM 🙏

So I put a small site together. If you'd be interested in attending the Ruby Magic Conference in Orlando (hopefully late 2027), I'd love it if you'd visit the site and let me know: rubymagic.dev

This is genuinely incredible! Reactivity like React for humans, and simple, clean html for agents and low-bandwidth users.

The recording of my #RailsWorld 2026 talk, where I introduced the reactivity in ReActionView v0.6, is now live on the Rails YouTube channel: www.youtube.com/watch?v=REtf...

I just published the slides of my #RailsWorld talk from Austin last week. Check it out, if you haven't seen the reactivity features in ReActionView v0.6.

Come join us at @sfruby.com this November! Last year’s edition was awesome, and I’m sure this year is going to be even better! ❤️ clouds.sfruby.com/e/2026-bits/...

yrby is getting to a really strong place. I’m running it in production, and I’ve expanded quite a bit beyond my meager early ambitions I want it to be the first-class answer for realtime collaboration in Ruby/rails, without having to reach for node or any other tool

Content update for the RubyEvents meetup guide! I’ve added some hard-earned lessons from meetup organizers for you to adapt. Turns out a good meetup is about so much more than just finding a room and putting someone on a stage. guides.rubyevents.org/meetups/

If you haven't submitted a talk proposal for Helvetic Ruby yet, now's the time! The Call for Proposals closes on July 31. Join us in Zurich for Helvetic Ruby, November 19–20, 2026 🇨🇭🍫🧀🗻 Not planning to speak? Early Bird tickets are still available, too! helvetic-ruby.ch

"There are plenty of places where you can dump your vibe-coded garbage – but this is not the same. Because you can actually scale up and do a legit system architecture with @miren.dev" Watch the full livestream with @chadfowler.com and @evanphx.dev here: www.youtube.com/live/1gjm9Gi...

I just released Insta, a new snapshot testing library for Ruby, live at RubyConf in Las Vegas! Extracted from Herb's test suite and inspired by @mitsuhiko.at's fantastic insta library for Rust. `gem "insta"`

I don't mind reading code written by agents, but I hate reading their PR descriptions. If I can't make myself read a PR description from Claude, I won't expect others to. Now when delivering PRs, I may not have written the code by hand, but I'll certainly write the description.

We love ruby events and we want to support their growth. These guides are a fantastic resource for new organizers and those looking for new ideas. Thank you to all the organizers who contributed, and @hansschnedlitz.com for putting these guides together. Welcome to the team, Hans!

RubyEvents Guides is now live. Over the last few months, I talked to Rubyists who want to help the community keep going. Some want to restart a local meetup. Some are organizing their first small conference. Some already run events and want to make the next one better.

The RubyEvents.org June 2026 Newsletter is fresh off the presses! This month's headliner is the new homepage and videos page. There's new ways to find videos that interest you and at the bottom you'll find new guides to getting involved with the community! www.rubyevents.org/announcement...

Save the date, mark your calendars, and decline the invite to the All Hands meeting! The second edition of SF Ruby Conference is happening Nov 10-12. Our first confirmed keynote speaker is @realgarrytan.bsky.social, president and CEO of Y Combinator and longtime Rails builder.

Had a blast a #RubyConfAT 🙌 The combination of technical talks and classical music was unique 🎹 Lots of AI inspiration. @batsov.net's talk about Rubocop 2.0 reminded me how special our community is. I got to meet @marcoroth.dev in person and geek out about Herb and Ruby tooling. Very fulfilling ❤️

Some photos from first day of RubyConf Austria:

Kicking off #RubyConfAT with the amazing @hansschnedlitz.com and @marcoroth.dev! Exciting weekend ahead!

Looking for something to do this weekend? How about submitting a talk to the #tinyruby #CFP? cfp.helsinkiruby.fi

We are back for the second day of @balkanruby.bsky.social! @marcoroth.dev kicks off the agenda with some hot takes about Hotwire and Herb. P.S. We found Nick! 😁 #Ruby #Rails #RubyFriends
