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

An interactive field guide to the Chrome DevTools Performance panel: waterfall, flame chart, LCP, CLS, INP, and the Insights panel.

A car alarm device, KARR, inside millions of cars has a security flaw that lets hackers unlock, track, even paralyze vehicles. There's a patch. The problem? Half of car owners who have the device installed didn't ask for it, and may not even know it's there. Thread👇 www.wired.com/story/a-devi...

A Device Hidden in Cars Across the US Leaves Them Vulnerable to Hacking and Paralysis. Patch It Now

Dealerships installed alarms in millions of vehicles—and left them in even if the buyer didn’t want them. Now researchers warn they can be hacked to unlock, track, and disable cars.

Irritating part of the AI ecosystem* is this reflex to create coded vocabulary that builds an unnecessary barrier to entry. MCP? Oh, you mean an API. Skills? Oh, you mean docs. Evals? Oh, you mean tests. * to be fair, this is actually any group of humans who want to differentiate Their Shiny Thing™

Alarmed at this trend of people finally realizing MCP is a pointless abstraction, then skipping right over publishing a regular boring API, and instead launching new CLIs for agents to use for some reason. It’s baffling.

Hi! I'm working on a new HTML feature: filterable select There are two proposed API shapes so far: 1. Nesting <input> in <select> 2. Sibling <input> for listbox <select> w/id ref Option 1 is more ergonomic, but would break selects in older browsers Thoughts? (Both currently in Canary w/flag)

My experience with agents is that it doesn't make my work "faster". In the end it costs roughly the same amount of time, if not longer But my role has shifted from "builder" to "sculptor", which is a completely different job. I hated it at the very beginning tbh, but I'm getting better at it slowly

The Chrome DevTools team are doing a "papercuts" sprint where they try to address lots of small, irritating bugs and annoyances. Reply with crbug.com links (no bug, no fix—that's the deal!) and will see what we can do. No promises though as some may be features/too big/unclear how to solve.
