I mentioned before that we’re switching Lighthouse Performance audits to the new and improved Insights. The same Insights that you can see in DevTools Performance panel traces. That’s happening in Lighthouse 13 due to be released very soon. Maybe even this week!

I've been implementing some improvements in my @11ty.dev blog, mostly related to performance and deferred code loading. I'm pretty happy with the results, and hope they might be useful to someone else too: infrequently.org/2025/10/11ty...

Esta semana hemos visto otro caso de marketing agresivo disfrazado de formación gratuita. Un curso online de 3 días anunciado como “gratuito” y con “certificado” que acabó siendo, en su último día, un embudo para vender un supuesto “Máster” de 1500 €. (1/4)

I'm in Liverpool this weekend. Chatted to a local old white bloke who spoke with pride about the city having the first mosque in the country, and the first chinatown. And… fuck, I needed to hear that kind of positivity.

Hey folks, I'm looking to schedule the next PerformanceObserver meetup and need some new CFP submissions. I have a few experienced #webperf speakers on there, but I like to break it up with either newer speakers or new-to-webperf speakers. performanceobserver.dev/call-for-pap...

Join us on September 16!

Well, dignity has left the building. I’m looking at walking pads for my standing desk. Fellow home office hamsters, which models are actually worth it? PS: Any "just take more steps" tips will be considered as emotional damages.

Really excited to be speaking @perfnow.nl this year—my favourite conference run by some of my favourite people! If you're into web performance (or wanna be!) and like a great conference with a super friendly vibe then pop along to Amsterdam at the end of October. Tickets selling fast! perfnow.nl

🚀 The #StateOfHTML 2025 survey is now open! ➡️ Take it now: survey.devographics.com/en-US/survey... 💡 Spending time to fill these out is an investment into your craft, as browsers are using the results to make prioritization decisions. You don't have to do it in one sitting (or even one device).

A 673 ms LCP is not terrible, but it could be better. I guess this LLM was trained using @timvereecke.bsky.social's Scalemates results 😂

Today we went for lunch at “El Pino,” a restaurant and pulpería in Vallirana (Barcelona). It’s our favorite restaurant in the area. I don’t have any pics because we ate everything before even thinking about taking pictures, but if you’re in the Barcelona metropolitan area, seriously, it’s worth it.

The State of HTML 2025 survey is now live! Big thanks to @lea.verou.me for taking the lead on selecting this year's questions and features, as well as suggesting quite a few improvements!

Just published a new section on my site to capture references to a lot of the essential web performance and fundamentals-oriented webdev resources I find myself continually directing folks to. Also, lots and lots of links to blogs I love: infrequently.org/links/

Hey folks, the next episode for the ⁠Eleventy Meetup is going to be a week from today! @kajkandler.bsky.social and @mwdelaney.me will be speaking. It will be recorded, but only live attendees get access to Q&A and live shenanigans 🙂 11tymeetup.dev #11ty @11ty.dev

Los migrantes representan ya el 41% del empleo creado en los últimos 3 años y con un récord: 3 millones de extranjeros afiliados a la Seguridad Social. Su aportación a la economía es clave. El BCE calcula que son responsables del 80% del crecimiento del PIB. www.rtve.es/play/videos/...

Grok and the truth.

Ayer tuvimos la mala idea de cenar paella. En un camping. En Francia. Las señales eran claras, pero las ignoramos. Solo diré que volcaron arroz cocido con colorante, pimiento rojo, muslos de pollo y mejillones en una paellera fría. Lo trajeron más rápido que la bebida. Y no es una exageración 😅

Ready for #GoogleIOConnect #BuildWithGemini

“Female” and “woman” are now banned words in USA research grants. “‘I guess a word that's not on here is “men,”and I guess a word that I don't see on here is “white,” so I guess we'll see what's going on with white men and what they need,’ Fielding-Miller said.”

Strong words by Alex Russell at JSNation today.

Import maps are a great way to minimize cache invalidation in your module tree. But up until recently, they had a ton of sharp edges. So we fixed them!! shopify.engineering/resilient-im...

I just saw an event with two sponsorship tiers. Partner. And Lover.

Speaking of seeing ppl IRL, the RSVP for the next SPDY Meetup event: PERFORMANCE AT SHOPIFY will close in ~100hrs. If you've not RSVP'd yet, no better time than now. 🎟️ Link in post below.

And we had a bug with FCP and LCP for prerendered pages. So if already moved to v5.0.0 then you should upgrade to v5.0.1!

Live Metrics screen feedback request! It's been about 6 months since we launched the Live Metrics screen in Chrome DevTools so a good time to step back and ask for any feedback on it. Do you use it? What's good about it? What could be improved about it?

[New blog post] Are CSS Carousels accessible sarasoueidan.com/blog/css-car... In this post, I share some important insights from examining the accessibility of CSS-only carousels that use new features introduced in the #CSS Overflow Module Level 5 spec. #a11y

Me, every time someone who knows nothing about Spain says that our work schedule includes a 3 hour lunch break because we take siestas every day…

In less than 24 hours, 99% of the power is back on. I can't imagine how complex this process is, but I'm proud (and thankful) for everyone involved ❤️ #SpainBlackout

Tell me you’re old without telling me you’re old 👵🏼

Someone hire this guy. He's one of the best. Hire him before someone else does.

Ohhh who would be interested in implementing INP subparts in Chrome/CrUX as part of a summer intern project? Or any of the other projects listed here. Plus contributing to Chrome means your code is used by literally billions of users—which so soo cool.

Interested in open source? Check out Google Summer of Code! Mentoring organizations for 2025 were just announced--185 open source projects. It's open to students and to beginners in open source. Applications open March 24, but connect with organizations you're interested in early.
