BlinkOn 20 kicks off today at Google HQ, and Igalia is there! We’ll be on stage twice today, with @seaotta.dev co-presenting the opening keynote with Penelope MacLachlan, and @jdapena.bsky.social delivering a lightning talk about timing. And we’ll have even more tomorrow!

Maintaining a downstream of #Chromium is complex. But, the bigger it is, the harder it is to maintain it. How to measure a downstream size? Why it gets big?

Container Timing has the potential to improve the capabilities offered by the web platform to content developers to understand the performance behaviour of a web or specific components. A new tool in the WebPerf toolbox!
The Bloomberg Terminal, believe it or not, is based on web technology 🌐
This deep-dive talk by @jason-williams.co.uk & @pcwilliams.net reveals what that looks like in terms of Chromium embedding.
It explains how we keep it blazing fast, including by adding a new Web Perf API: Container Timing 🔥

Myself and @pcwilliams.net continue to be humbled by the response we had at @perfnow.bsky.social. Our talk “Bloomberg Becomes Browser” has been published! You can watch it here: youtu.be/y1MCLZm8yAY?...

BlinkOn starts tomorrow!
I will be hosting a breakout session about Linux #Chromium running in low memory devices, and delivering a lightning talk about the work I have been involved to improve the #V8 support for native stack walking profiling.

New blog post! V8 profiling instrumentation overhead blogs.igalia.com/dape/2023/11...
When profiling Javascript CPU usage, JIT-compiled code needs instrumentation. Unfortunately, in V8 it is disabled by default because of its overhead. I ran benchmarks to measure that. cc @igalia.bsky.social

webOS OSE 2.24.0 is out!
Main highlights from web stack side: It is now based on Chromium m108. And we now use LLVM Clang and libc++, instead of libstdc++ and GCC. That way we align better with upstream, far more tested with this toolchain.

Though Chromium official toolchains for Linux are based on LLVM Clang and libc++, GNU toolchain is supported as a community effort. In the post I write about current status (working!).
