This week, we had the great opportunity to deliver the Web Performance Workshop to the amazing tech team at Back Market

It was two days of sharing knowledge, answering questions, and identifying areas for improvement.

Thanks @andresas.dev @nucliweb.net it was a blast! Came away with actionable tools and insights I'm looking forward to applying.

“OpenAI’s Windsurf deal is off — and Windsurf’s CEO is going to Google” - The Verge just broke the news

A reminder that until a deal is done: it’s not done. Anyone treating claims of OpenAI buying Windsurf as a fact - well, it was not…

This quiz uses V8's Date parser to demonstrate that the JS Date spec is unintuitive in many ways.

Thankfully work has been underway to fix this for several years 👍

Temporal is the replacement for the Date API. It shipped in Firefox 127 in May 2025 🚀

Nuxt 3.17.0 introduced reactive keys for useAsyncData 🚀🚀
github.com/nuxt/nuxt/re...

I regularly encounter two limitations with Nuxt's useAsyncData: it lacks reactive caching keys, and it's prone to request cascading since you need to await useAsyncData to block navigation during the request.

And... I think there's some very good news recently ✨🧵

An official package to handle RSC in Vite is a cool news! I assume this will make it easier for new Vite-based React frameworks to appear.

YouTube video by The Pragmatic Engineer Building Windsurf with Varun Mohan

Interesting interview with Varun Mohan, CEO of Windsurf. It is very technical, discussing the challenge of code LLMs that need to “fill in the middle” and how they evaluate models automatically. He also shares his take on what the future looks like for software engineers.

"migrate all systems off COBOL quickly" is a funny concept. If it were possible without breaking anything, it would probably have been done already.

THANK you for mentioning this. I felt like I was going crazy when people would say SSR is *only* good for SEO
