Almost three years since I helped ship the first VegaOS device on React Native. Awesome to see the progress—and to finally get it into other developers’ hands.

With React Server components, we’ll need to learn how to combine client and server components, use “different” data flow model. I appreciate Dan’s simplified explanation of the concept.

While RAG is the most common way to expand a model outside its training set, Bharani Subramaniam and I now finish our current batch of patterns by examining our experience with Fine Tuning, where we learned to prioritize curating high-quality data.

I'll definitely be turning on erasableSyntaxOnly:true in TypeScript 5.8! Very nice!

It enforces that all type definitions are annotations only, so when you strip the annotations, you end up with exactly the JavaScript you would have written without annotations (no enum, no namespace, etc)!

@danabra.mov what are you using for FPS measurements?

You kinda expect RN pages as outdated unfortunately due to amount of changes in ecosystem.

Largely for typical dev stuff, folks don’t need to go beyond React Devtools, or Hermes/Experimental Debugger.
When problem comes with native, those devs are already familiar and use perfetto/xcode.
