As a climber, I can’t visit Tokyo without having a session at BPUMP Ogikubo 😁

If you’re curious about how Ruby’s official documentation is generated and deployed, I documented the entire process a while ago at github.com/ruby/docs.ruby…

This, and the “Run In Terminal” next to it, are two of my favorite features of Ruby LSP 😁

6 years later and Asakusa.rb still gave me the warmest welcome! Same good vibes, delicious food, and great #rubyfriends. So happy to be back!

My teammate Alexandre Terrasa wrote a great post about using inline RBS with Sorbet. We’ve been slowly adopting it at Shopify. And while we’re still improving Sorbet and all the supporting projects, it’s already working well! railsatscale.com/2025-04-23-rbs…

I’ve been visiting Taiwan for the past few weeks, and almost everyone—family and friends—has expressed concerns about a potential invasion in the next year or two, either explicitly or indirectly. Sometimes we even jokingly say, “Hope to still see you here next year.”

A brand-new, pure-C RBS parser has been merged 🚀 It has no Ruby runtime dependency, so it can be embedded in Sorbet, JRuby & other tools. It’s the result of months of work by Shopify’s Ruby DX team: Alexander, Alexandre Terrasa & me 😁 Details in github.com/ruby/rbs/pull/…

BTW, I’ve opened a draft PR for this: github.com/Shopify/ruby-l… We’re now waiting on a new VS Code API to let extensions configure the MCP connection, which will make the setup simpler & more robust.

Read The Nice Manual! In the happy world of #Ruby, we don’t #RTFM, we #RTNM ⬇️

Proud to land my first ZJIT contribution this week—in Rust! github.com/ruby/ruby/pull…

Never imagined I could do a 200% bodyweight pull-up (my weight + 60 kg plates) even in my early twenties—yet at 31, I got it today 😛

As a next step for Herb, I'm happy to announce the release of the Herb Language Server and Visual Studio Code extension. Built on top of Herb's HTML-aware ERB parser to bring diagnostics, instant feedback, and structural awareness to HTML+ERB files. Still early. Feedback is very welcome!

Been thinking about how AI coding agents are changing my career. To me, the appearance of coding agents and the advancement in models in the last year have changed how I learn and work. Will share my experience in a blog post soon 🙂
