It's long past time we had a standard way to load CSS asynchronously. link[async] should work just like the tried and true print-media hack, but without the major downside of javascript reliance for applying CSS. Join me with a plus one here? github.com/whatwg/html/...

Fuck cancer. My little family has been torn apart. Our cat Ivan had to be put to sleep on Friday. We are blindsided – he’d had a little cough for a couple of weeks which was believed to be asthma or maybe pneumonia, but it turned out he had an aggressive lung cancer and deteriorated quickly.

My talk from this year's We Love Speed is on YouTube! 👇 In "Tight Mode: how browsers REALLY load web pages", I take a very deep/very nerdy dive into why browsers sometimes intentionally delay loading resources, why they all do it differently, and why they should *stop clowning around* 🤡 #webperf

Say hello to `inverse-subset`! The idea is from a conversation with @andydavies.me at #perfnow. When you have a complete font and a subset e.g. Latin, generate another subset consisting of everything not in the original subset. E.g. all characters that are NOT Latin. npmjs.com/package/inverse-subset

Would you want core web vitals In Safari? Can you help me understand how you would use them and why numbers in one browser isn’t enough? (These may sound like silly questions, but I’d love to understand *your* specific context and use cases)
