Anyone using HTTP/2 server push with libcurl? If you use this feature in libcurl, please let us know. It is being deprecated all over, including in specs, browsers and servers and I believe the time has come for us to drop it from libcurl in the future as well. So I'm curious to know if anyone […]

An enormous amount of the world’s CI and automation runs headless Chrome, all of it on x86—until last week. Chrome now ships official arm64 Linux builds. AWS says Graviton uses up to 60% less energy for the same performance. Chrome for Testing coming soon 🥳 calibreapp.com/blog/chrome-...

Technology, like time, cannot be stopped in it's relentless march forward. Much as us old timers would like to slow down one or the other just a little bit… In light of that, Chrome 153 will come with an updated list of modern devices for emulation mode—with nice categorisation—thanks to @jackf.io

We are going to spend the next 20 years discovering and dealing with the mental health effects of over-reliance on AI.

One of the things that we at Chrome have been thinking about is a way to do declarative route and navigation matching **in CSS**. Together with @nomster.bsky.social and @dbaron.org I’ve been working on it for the past few months, and next week we’ll be presenting our work at the CSSWG F2F meeting.

In my audits, reading the Performance profile is where people get stuck: the flame chart and waterfall look like noise at first I built an interactive guide to make them click, every figure is interactive, plus LCP, CLS, INP and the Insights panel perf.reviews/profile-guide #WebPerf #DevTools

Great thread on how best to file bugs with browsers if you want to increase the chances they’ll be fixed.

A thread on how I file browser bugs:

@nomster.bsky.social's Two-Phase View Transitions example here shows an MPA (multi-page application) navigating between to separate pages (two full page loads), with a smooth skeletal loader animation between them. noamr.github.io/two-phase-vt...

Great to see Calibre switching to measuring Core Web Vitals for SPAs! We’re really excited for the soft navigations work that enabled this and can’t wait to see what insights it leads too.
