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.

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 🚀

Yep, @atinux.com came by in October, and now @thealexlichter.com is partnering with us to bridge @nuxt.com with fairly big projects like the @backmarketofficial.bsky.social web platform.

Double trouble! Today airs one of two Nuxt special episodes on DejaVue. Our guest is nobody else than @atinux.com, the creator of @nuxt.com and @nuxtlabs.com
Together with hosts @michaelthiessen.bsky.social and @thealexlichter.com they talk about the origin of NuxtLabs and Nuxt, differences & more!

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 ✨🧵

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.
SCOOP: DOGE wants to rebuild SSA's codebase in months, risking benefits and system collapse, sources tell me.
The plan is to migrate all systems off COBOL quickly which would likely require the use of generative AI.

DOGE Plans to Rebuild SSA Codebase In Months, Risking Benefits and System Collapse
Social Security systems contain tens of millions of lines of code written in COBOL, an archaic programming language. Safely rewriting that code would take years—DOGE wants it done in months.

What if we could use mocks outside a test environment?
This is something I’ve been experimenting with lately. My goal is to create a "playground" app that runs with mocks by default. This app could then be used for demos and integration tests. 🧵
