The number of connection address and protocol combinations keeps growing, and every browser behaves differently. With Happy Eyeballs v3 browsers will fall back to a working option faster and more safely. This session will show what its performance impact looks like. Max Inden at perfnow.nl

In this deep-dive session, Tim will use real-world data and performance metrics to show how scalemates.com became the fastest and largest scale modelling website in the world. You’ll leave with practical, actionable insights to push performance even further. @timvereecke.bsky.social at perfnow.nl

Today I learned the hard way that evidence synthesis is about to get a whole lot harder with AI-generated fake publications. Particularly unpleasant: I learned this while hunting down a climate change impact attribution study for a systematic review.

I gave a talk at EMF titled "Men in Tech #YesAllMen", in which I told my experience of being a woman in tech. I was afraid to publish it in case it affected my current or future employment. With all the current news I would like to add my 2¢. So here is the recording: youtu.be/WXL6K1lhvt0?...

What if we could provide websites that have the ability to do their thing while being offline? In this talk, I’ll show you how I’ve harnessed the native web APIs to implement offline capabilities while minimizing the amount of Javascript to execute in the browser. Aleth Gueguen at perfnow.nl

Mobile Core Web Vitals are being built with real user data, and are tied to both business impact and a specific fix. But a lot doesn't transfer from the web: LC assumes a page load, CLS a document. This talk shares the first public look at Mobile CWV. @cliffcrocker.bsky.social at perfnow.nl

Aznar, pidiendo el voto para Pedro Sánchez 🗳️

I don't want to brag, but I finally met @tamethebots.com in person! 🤩

On a scale from zero to “I design my own backpack with its code in it”, how much do you like @11ty.dev?

I was so lucky to start this project with people I admire so much... and even luckier with all who joined after. A kind of experiment still running today. A safe place where effort and talent are used to make the world a better place. I can proudly say: 25 years ago we were creating Igalia.

Just returned from a couple of weeks in Egypt. It's surprising that the weather feels hotter in my town in Spain than it did in Cairo and Hurghada 🥵

Yet another case of economic illiteracy from the Trump administration. The US, lacking vibranium reserves of our own can't influence US production with tariffs on Wakandan exports. www.bbc.com/news/world-u...

Hoy hace (al menos) 4 años que vivo con esclerosis múltiple. Y doy mil gracias por vivir en un país con acceso a los mejores tratamientos posibles. A tan solo 15min de mi casa. Incluso viviendo en una pequeña isla de Canarias. Tratamiento que seguramente no podría pagar de otra manera.

¿Soy yo o todos los países del mundo (excepto Israel) apoyan a España en el partido de esta noche? PS: ¿sabéis quién estará metida en un avión durante la 1ª parte partido? PS2: Friendly reminder que De la Fuente fue uno de los muchos que aplaudían mientras Rubiales gritaba “¡NO VOY A DIMITIR!”

Vale, resulta que me precipité y sí es una burla. No leí hasta el final porque ✨señoras con prisas que hoy no han tomado café✨ Aquí el texto completo que sí demuestra que se ríe de no decir nada con palabros. No critica los anglicismos como tal, pero sí las frases vacías: bsky.app/profile/miga...

I'm trying to build something at #GoogleIOConnect #BuildWithGemini, but the internet is basically not working at all… 🫠

I've listened to this song so many times this week that I feel like I'm starting to understand French (ok, the fact that it's a Latin language also helps a lot). It's not usually my kind of music, but I have to say that I enjoy listening to a lot of Stromae's songs. www.youtube.com/watch?v=oiKj...

🚨 BREAKING NEWS! 🚨 I’m happy to say that I’ve finally found a way to do anything on the web that's slower than JavaScript: decaf coffee ☕ Can you guess who spent 20 minutes trying to validate a local fix in the production environment? 🤦🏻‍♀️

The State of CSS 2026 survey is out! These survey's are a huge signal to the browser makers on what people want, and the more people fill the out, the better that information is. survey.devographics.com/en-US/survey...

I think this is the first time I've seen an actual 418 HTTP response code in the wild! 🫖
