Good morning #SFRuby Conference! ☀️ I’m excited to have an overbooked workshop for Active Agent this morning and can’t wait to show many of you how to build AI in Rails. For anyone who can’t make it, we’ll be sharing a video after the event!

I'm very honored to have received this year's RubyPrize from Matz's hands in Matsue last Thursday, recognizing my work on Ruby and its development tools. I can still remember how nervous I was asking Matz for a picture back in 2016 😂 Time really flies (Photo from @hsbt.org ❤️)

It's so nice to see open Avo apps. I love how @palkan_tula implemented the filter and actions inline with the resource. Also cool to watch @paolino's RubyLLM in the wild too. github.com/evilmartian... github.com/evilmartian...

oof, what a disappointing way to end more than 15 years of open source work. (summary by @duckinator.bsky.social at pup-e.com/goodbye-ruby...). good luck to the remaining RubyGems team, and it’s time to focus my energy on new projects that I’m truly excited about, like rv.dev

At Rails World 2025, I introduced ReActionView, an initiative to explore what's possible in the Rails view layer for 2025 and beyond. As part of this, I announced Herb::Engine, an ActionView-compatible ERB engine built on top of the HTML-aware Herb Parser. #RailsWorld2025

I am the kind of person who needs to see someone use a thing in order for me to understand that thing. Sometimes reading the docs is not enough, so @tonsoffun.bsky.social gave me a white glove intro to Active Agent and I immediately knew that there is no other way of building with AI in Rails.

Today I released the initial version of my first-ever gem, called Active Operator. It's an extraction (and revision) of a pattern I've used for calling external APIs, and then storing and processing their responses. Here's an intro I did. ☺️ www.youtube.com/watch?v=cFfz...

I keep hearing: “I’ve seen @activeagents.ai on Twitter, but I still don’t know what it does.” 😪 Including from @adrianthedev.com. So we got on a call & built an AI invoicing agent together. By the end: “Okay... now I REALLY get it!” Here's what finally clicked... 👇
