Lots of people incorrectly claiming Chrome/Google "tried to kill JPEG XL". Just because an engine chooses not to be the FIRST to ship a new technology does NOT mean they are trying to kill it!

When we first reviewed JPEG XL, as far as we could see no other browser engine wanted it. Our judgement was the benefit wasn't worth the cost. Then Safari decided otherwise and shipped it. Once Mozilla expressed their openness to shipping, it was inevitable that Chromium would too.

It’s been a very hard year - Andy Bell
Unlike a lot of places in tech, my company, Set Studio/Piccalilli has no outside funding. Bootstrapped is what the LinkedIn people say, I think. It’s been a hard year this year. A very hard year...

More detailed paint timings coming to LCP.
TLDR:
- paintTime is after the style&layout and should be roughly interoperable between browsers.
- presentationTime is implementation specific (Chrome's is pretty near when pixels are actually drawn).
LCP time stays the same as the latest timestamp.

Considering starting a "hang up any video call immediately when the word 'agentic' comes up" policy. Think that would be a good career move? What about as a mental health move?

When a user closes an issue in an open source project with a snide remark after I propose they do a bit of debugging and research on their own is not the evil comeback the user probably thinks it is.

Chrome 143 will start rolling out today (most users get it next week).
It includes a new set of options for your webperf traces — including saving sources & source maps:
developer.chrome.com/docs/devtool...
This makes it easier for those viewing traces outside of the page load to get more context.
