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

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.

Ruby and Rails are great for building AI features.
At thoughtbot Open Summit, we want to help dev teams unlock the full potential of Rails for AI, because we believe Rails is tailor-made for working with external services like LLMs.

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.
