Spotify · YouTube - Open Source at Scale with Corbin Crutchley (Ep. 29) · 52 minutes
🎙️ Corbin shares how a 30-minute conversation with Tanner Lindsley turned into leading TanStack Form, why versioning is a social contract not a technical one, and the near-quit moment that changed how he thinks about maintainer wellbeing. Spotify · YouTube - PostCSS, AutoPrefixer & Open Source at Scale with Andrey Sitnik (Ep. 28) · 58 minutes
🎙️ The creator of PostCSS shares how browser discrimination in Russia drove AutoPrefixer, the pledge that forced PostCSS 8 to ship, and why adding 10x more AI agents gives you 10x more coordination problems. Spotify · YouTube - React Server Components at Scale with Aurora Scharff (Ep. 27) · 52 minutes

- Now more then ever, you need to master custom ESLint rules I spent three days building a custom ESLint rule and accidentally learned how JavaScript actually works. ESLint is just walking your code's syntax tree and running functions against each node. Once you see it, you can enforce any coding standard automatically instead of arguing about it in PR reviews.
- You really, really, really don't need an effect! I swear! Before you write another useEffect, ask one question: is this syncing with an external system? If not, there's a better way.
