Just arrived at the airport, heading from San Francisco to Amsterdam for Rails World 2025! Excited and can't wait! :) If you're in Amsterdam, shoot me a message - I'd love to say hello. Will land a bit before noon Monday #RailsWorld

Added notification hooks to my ~/.claude/settings.json file to have Claude Code notify my using terminal-notifier when it needs my attention - make sure to enable notifications for terminal-notifier in System Settings on Mac after you've installed it. Link in the replies.

Managed to implement a share extension in my little Rails Hotwire Native Link-read-it-later app. You can go to a website in Safari and hit share, and send it to the Hotwire Native app so you can save it and read it later

Just got back home from #RailsConf - what a great conference. It was great to see familiar faces and meet up with old as well as new Ruby friends. I miss you all! Can't wait till we all get the chance to hang out again

I love how Claude Code creates a checklist before tackling a problem based on your prompt. It provides a clear, easy-to-read overview of its plan, making it simple to follow along as it writes the code. 🧑‍🍳😚

I haven't used Cursor's AI features, except for their tab suggestions, in weeks. Lately, it's been all about Claude Code for me. I find it much better and more enjoyable to work with.

If you do any sort of stripe checkout development, do yourself the favor and add the test card to your password manager so you don't have to waste time smashing that into the credit card form every time.

We're adding an illustrious new speaker to the Sin City Ruby lineup: Dave Thomas (@pragdave.bsky.social), perhaps best known as the co-author of The Pragmatic Programmer, will be our keynote speaker! Sin City Ruby takes place April 10 & 11 in Las Vegas.

Have you ever wanted to see Sutro Tower up close? Now you can! I'm releasing a very high quality model of the tower that you can easily fly through on your own, thanks to very cool developments in Gaussian splatting 🧵...

With Apple TV+'s Severance Season 2 coming out next week, we decided to rewatch the first season (it's been almost three years!). Had forgotten how good it is. I thought starting just over a week before the release would give us enough time to finish it, but we ended up finishing in just two days! 😅
