I'm looking to recruit talented senior engineers that have experience related to web performance monitoring and optimization. If that sounds like you—or someone you'd highly recommend—please send me a DM and I’ll share more details! The role is 100% remote and async-first.

Cursor's `Tab` behavior is impressively good but the cognitive overhead of a different IDE (and overriding my keyboard shortcuts) is driving me crazy. 😵

@tunetheweb.com does Chrome DevTools AI allow you to change the wheels from round to square? Very irresponsible! 😂 Context: chrome.dev/cinemai/devt...

Baseline is now available in VSCode. This is a really neat feature with no extensions needed. (catching up on Google I/O 😅) Read more: web.dev/blog/baselin...

Pocket will be discontinued. 😔 What do you guys recommend for storing articles to read later (ideally works across all devices)? support.mozilla.org/en-US/kb/fut...

Do you want to keep your kids busy? Give them LEGO instructions from ChatGPT. 😂

Back from a peaceful week in the Polish countryside with the family.

There's a lot of talk about 'vibe coding' at the moment. Andrej Karpathy's tweet that introduced the term is often mentioned. I suspect, however, that many people who are promoting the idea in the context of commercial product development may not have read the whole tweet.

Hadn't heard of "outrage fatigue" or "doomscrolling" until recently, but lately I found myself wasting more time than I usually would on social media. www.scientificamerican.com/article/outr...

How to Avoid News Burnout and Outrage Fatigue

Outrage fatigue can wear us down—but we can take care of ourselves in an onslaught of overwhelming news.

If you're using Speculation Rules there's a small bug in Chrome 133 (just rolling out now) where DevTools + Local Overrides causes prerenders to crash 😢 This only happens with DevTools open and when Local Overrides are enabled so shouldn't affect most of your users—but annoying for us developers!

Any recommendations for non-fiction books? Probably not politics or history, but almost anything else is good. 😁

I asked Gemini AI if today is the 3rd Fri of the month. Today is Friday, Dec 27, 2024. To determine if it was the 3rd Friday of the month, we need to find the dates of all the Fridays in Dec 2024. * Dec 1: Sun * Dec 2: Mon ... As you can see, Dec 27, 2024 is the third Friday of the month. 🤦

Did you know that jQuery outperforms React, what? 😳 Sounds like clickbait, but is reality. The HTTP Archive shows 82% of sites that use jQuery have good INP on mobile📱, while only 67% do when they use React⚛️. Not just sites, also libraries. Let's fix that👇#webperf kurtextrem.de/posts/improv...

Nothing to see here, just JIRA taking almost 6 seconds to open a dialog. 🤷 🤯

I announced it yesterday, but I'm very excited for the @httparchive.org's stream I'll be leading in under 2 weeks: ✨ The Web Almanac Live! ✨ We'll discuss findings re: how the web is built. Data collected over months of research across 17 million sites + published almanac.httparchive.org/en/2024/
