Feels nice to be back in Czechia! I'm currently transiting from Prague to Brno for Euruko 2026. I think the last time I visited was almost 14 years ago, shortly after first joining Red Hat. I have a free day before and after the conference so I'm hoping to do a bit of touring.

My own experiments using AI for JRuby work have been mixed, but I can report a great success: contributions from people that never would have attempted such things before, like Ruby core devs and Rubyists with no JVM experience. So many PRs lately!

I recently had a nice chat with @eSquareDesign about the past, present and future of JRuby... including some myth debunking that might help Ruby folks look past the "J" to the amazing tech underneath. Check out the video here:

And thanks to JRuby friend @cglee I now also have a ticket! Super excited to join the hallway track and show folks how to do more with Rails using JRuby! 🤩

Good news! I will be in Austin during Rails World 2026 and available for JRuby office hours. I'm still looking for a ticket (budget is very tight!) but I can't miss out on meeting Rails folks from around the world. If you're a JRuby user or might like to be, let's have a chat!
