DHH: 'Turbo 8 is Dropping TypeScript' — As we might say in England, DHH knows how to “throw the cat among the pigeons” (^explanation) and get people talking. This time, TypeScript is his target. He’s not a fan and he doesn’t want it in Rails’ Turbo. Unsurprisingly, this sent TypeScript-land into a tizzy on Twitter, but bad luck, it’s already been ripped out.

Flipper 1.0: A Feature Flag Solution for Rails — If you want to easily turn features on and off for different users or groups of users in your app, Flipper is for you. It began life while John worked at GitHub (he famously built an app that was acquired by GitHub) and now not only deserves its 1.0 milestone, but it’s now a more serious project and product overall, with Garrett Dimon coming on as a full-time developer on the project, and a new free tier to the Flipper Cloud hosted service.
