"Thundering Herd" is my new favorite way to sound super smart in a presentation. 🐃 😁 en.wikipedia.org/wiki/Thunder...

"Access from your country was disabled by the administrator". Lol, wth? 🤷

Back in Amsterdam for @perfnow.nl. Hope to see you there. 😊

I made a quiz about the JS Date parser is. It's very easy and you will score very high. jsdate.wtf

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. 😂

I finally joined the #framework club. 😍

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.

Hey folks, the next episode of PerformanceObserver is now scheduled for 16 April with @verlok.bsky.social and @ethangardner.com ! See all details at performanceobserver.dev including add to calendar links with the join instructions. #webperf

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...

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'm so excited to announce a new meetup I started! PerformanceObserver is a virtual meetup for the frontend web performance community! The first event will be announced shortly. You can join the newsletter to make sure you don't miss an event. #webperf performanceobserver.dev

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. 🤦

📢 Just a reminder, we're just under 24hrs from this stream tomorrow where we talk to authors from the ✨ WEB ALMANAC ✨ and the data they pulled. All links below. Streaming on Youtube, LinkedIn, and other platforms. See you tomorrow.

A great read from @kurtextrem.de with lots of useful links and actionable items. 🙌

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/

Just came across this useful list from @mandymichael.bsky.social with font performance resources. 🚀 github.com/mandymichael...

My talk from this year's We Love Speed is on YouTube! 👇 In "Tight Mode: how browsers REALLY load web pages", I take a very deep/very nerdy dive into why browsers sometimes intentionally delay loading resources, why they all do it differently, and why they should *stop clowning around* 🤡 #webperf

Super interesting talk on advanced performance techniques from @timvereecke.bsky.social for #welovespeed. 🙌 www.youtube.com/watch?v=rjUr...

@bram.us Could you recommend some reading material to help me debug View Transitions (cross document, same origin) please? I have two sites with identical CSS, on one site they work as expected while on the other they only work when the user presses back/forward buttons.

The AT Protocol is a super interesting idea. I'm curious how it will evolve over time, but the concept is 🤯.

what gif pops up when you type in your name? 😂
