Wrapping up the writting part for my talk at @perfnow.nl this weekend and I'm beyond excited for this one. Prepare for a deep dive folks!

performance.now() is coming! Umar Hansa will teach you about automated workflows using coding agents that work with the DevTools protocol, browser automation, and Model Context Protocol, and will show how these tools can be integrated into your development process. perfnow.nl/speakers.htm...

performance.now() is coming! The Long Tasks API told us that our scripts were busy, but didn't tell us why. The new Long Animation Frames (LoAF) API provides details on what Main Thread activity caused the long frame. @andydavies.me explains. perfnow.nl/speakers.htm...

performance.now() is coming! As tooling improves, is performance testing becoming any easier? @csswizardry.com, who spends every day auditing client projects,, thinks confusion has increased. Let's ensure that every test we run has a purpose and gives us useful data. perfnow.nl/speakers.htm...

performance.now() is coming! The night before the conference, 29th of October, @mozilla.org organises performance.sync(), the pre-meetup where you can meet your peers to mentally prepare for two days of information overload. They're also looking for a few people to present. luma.com/ziykhh4y

Avoiding the fomo this year by eagerly being a part of #perfnow in 2025. Tickets on sale now to help you avoid that fomo too. perfnow.nl/speakers.html

If anyone wants tickets, you can buy them. There's even a few early birds left. And there are some speakers to admire. We'll run an official announcement when #cssday is done, but the sentence above gives the gist. perfnow.nl/tickets.html

Well, actually ... perfnow.nl/speakers.html

... we're going to announce start of ticket sales to the mailing list first. The rest of the world will follow later, and will likely miss out on the cheapest tickets. So if you want those cheap tickets, make sure to subscribe to our mailing list via perfnow.nl/subscribe

And ticket sales hasn't even started yet! That's the spirit!

#perfnow I have finally got my slides online! They are very media heavy so please be patient, but Keynote exported them all and I have uploaded them to www.jackf.io/talks/perf-n.... You'll find my slides and also all the links I mentioned during the talk.

At @perfnow.bsky.social there was a great talk on "Third Party Woes" by @gri.gs I think it's an area that anyone who works in #webperf is unfortunately too familiar with. I've written a quick blog on how I think this should be addressed by the businesses involved stuart-mcmillan.com/blog/busines...

2022 starter pack now also mostly ready, though Katie Hempenius, Nolan Lawson, and Sharell Bryant don't appear to be on Bluesky. go.bsky.app/QkwK3Le

Thank you thank you thank you @perfnow.bsky.social for another amazing year! The view from the stage was phenomenal today - the attendees and speakers were lovely, engaged, and I learned so much! Can’t wait to see you all again next year! 💜 #perfnow

On our way back from @perfnow.bsky.social, had an amazing time. See you all next year!

On my way back from @perfnow.bsky.social. Amazing event, people and conversations, as always. Going back with a full heart, and an even fuller TODO list of learnings to apply and collaborations to follow up on. Till next year, #perfnow!!

Until the next @perfnow.bsky.social ✌️ It seems we’ll all be coming in Halloween x Perfnow costumes. @tammyeverts.bsky.social looking forward to your zombie FID look 🧟‍♀️ #perfnow #webperf

Yesterday at @perfnow.bsky.social, @pcwilliams.bsky.social & @jasew.bsky.social told the story of how the Bloomberg Terminal was migrated all the way from custom hardware over to modern web tech. We needed more from that stack leading to contributions to many web APIs. The latest: Container Timing!

@perfnow.bsky.social you have been amazing. #perfnow, you are the best community, the only disappointment is that I usually only see you once a year. Also, isn't this so much better than The Bad Place?! 💙

I have been assured by @tkadlec.bsky.social and @csswizardry.com that you can work in #webPerf if you are below 6ft - @perfnow.bsky.social

performance.now() 2025 will take place on 30th and 31st of October, 2025. #perfnow.

The too-many-stroop-wafels line is really easy to see just after you've crossed it #perfnow
