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!

My experiments with agent-augmented dev feel like "coding by dictation", and always require manual review and MANY follow-ups. Code style: terrible. Naming things: terrible. Math: terrible. Forward-thinking design: terrible. Unsure if I'm more productive or less. 🫤
