DHH's recent observation about AI resonated: “"As soon as I'm tempted to let it drive, I learn nothing, retain nothing."” When he lets AI take the wheel, his learning stops. Knowing how you learn best is crucial and I respect that. But his tweet reminded me of my first week with Rails many years ago. One command - rails generate scaffo...

Kieran Klaassen and team mates shared their Claude Code workflow a few days ago. They broke down their process, showed what they built, and yesterday Kieran posted about the (potential) API costs a workflow like this has (or would have if not for Anthopic's Max plan). The response? While some were curious, the critical voices dominated...

I recently opened a pull request on a new project and, along with the usual details, included a short demo screencast. I do these often because they’re low-effort but high-impact.

As part of the Rails 8 milestones, DHH added a browser guard which he explains thus: “To take full advantage of our #nobuild defaults, we need to ensure that developers have easy control over which versions of the major evergreen browsers they intend to support, and guard their application from being accessed by unsupported versions.” ...

I upgraded a bunch of sites to Rails 7.1 recently and the ones deployed on Heroku started to show some massively increased memory usage: How could my app that was using ~128mb of memory be using four times as much with Rails 7.1? Well, its turns out that there was a change made to the default Puma config to make use of all available co...

When receiving and processing incoming emails with ActionMailbox, you may come across issues with particular emails that you need to debug. There is a tiny section in the Rails Guides about how to work with ActionMailbox in development. But how do we get an email that caused issues in production and debug it in development with the too...

I’ll write something soon. I promise.
