Instant purchase, I loved attending all day hey and it smaller talk events when living in Leeds.

I once managed to get copilot to say Monday didn't end in a Y because I asked it to write a unit test to test which days of the week actually end in Y. It couldn't find a failing path so it decided to confidently be wrong.

Trevor Philips tries to get Zack Polanski to trip up on the issue of trans Polanski responds with a slam dunk, a home run, a touchdown - whatever your sports metaphor is 👏

Storybook 10 is here! ✂️ ESM-only (the only breaking change!) 🧩 Module automocking for easier testing 🏭 Typesafe CSF factories Preview for React 💫 UI editing and sharing optimizations 🏷️ Tag filtering exclusion for sidebar management 🔀 Svelte async component support

We often hear that folks want "wrap detection" in CSS (i.e. when a flex item shifts into a position where it wraps over to the next line) What is a real-world example of a use-case you would need this for?

Ghost of Yotei is a stunning game and I absolutely love the wolf dens missions.

Fellow #perfnow fellows, a reminder that PerfPlanet calendar is coming this December for another edition. And it needs YOU. Please ask if you have any contribution ideas or concerns calendar.perfplanet.com/contribute/

I wonder if they are using the Brexit countdown clock until they can remove her. Interesting that skynews is reporting this as skynews reporter beth always thought hacking was funny.

“What happens when you want to center a div in Chrome?” — @michael-hladky.bsky.social at #perfnow This would make a great interview question that would give a variety of different answers. #webperf

Farage: epic grifter

JavaScript top-level await is no longer considered 'baseline' due to a pretty big Safari bug caniuse.com/mdn-javascri... The module graph fails in cases where two modules import a third at the same time. Demo: random-stuff.jakearchibald.com/bug-repros/t... It's best to avoid the feature for now 😔

Hey, did I miss you in my unscientific perusal of my feed just now for folks who are active on Bluesky and post their own content (not just repost others)?

Breaking: The Supreme Court is now officially considering taking up a case overturning same-sex marriage. This is the first time in history the court has considered rolling back this right.

Okay that's enough of this timeline today.

I don't want AI, I just want to open an application or file I need every now and again.

Daisy Cooper, "Will the Prime Minister Keir Starmer ask our security services to assess the threat that Elon Musk poses to our democracy"

Straight to the all inclusive bar after checking in.

So turns out React throws hydration error on <template> html element existing in the initial html🤦‍♂️ must be because it a document fragment, but they goes that idea to build some sharable web components.

OK, we're down to our last tickets. There's still room for people to join performance.now() on 30th and 31st of October (in two weeks and a bit), but it's time to decide. https://perfnow.nl Last tickets at https://perfnow-2025.eventstack.shop

"Time to Brand Identity" iankduffy.com/articles/tim... It's tempting to be drawn into thinking that the Largest Element is the most important one on the page. @duffeh.bsky.social covers how to measure other perhaps equally important visual elements with ElementTiming (one of my favourite APIs)

Huh, TIL there’s an <output> element, and it can be used to display the result of user inputs in a screen-reader-friendly way! I can think of a bunch of places I should be using this 😄 denodell.com/blog/html-be...

Seeing the clips of @zackpolanski.bsky.social absolutely rinsing Zia Yusuf has fixed my mental health in a way nothing else could

I was not expecting that. #ghostofyotei

Bold assertion from the woman who once hacked into another MP’s website.

Started playing Ghost of Yotei.

🔴NEW🔴 Thread 🧵 @bylinetimes.bsky.social can now reveal that, during the crucial period when convicted Reform leader Nathan Gill was most active, working directly with Russian President Vladimir Putin’s most senior ally in Ukraine, he was also one of Nigel Farage’s closest confidantes 1/12

New articles: Your brand identity is critical to establish trust and quality, so on the web, it is important to load it fast and not later, to avoid harming your users' perception of trust and the likelihood that users will purchase from the site. iankduffy.com/articles/tim...

We all have a choice. The Internet is ours.

What's next? Playing badminton with Skelator?

Cool, we know exactly who Guillermo is now.

This tweet has been doing the rounds on Twitter now that Nathan Gill has pleaded guilty. If only someone had tried to investigate UKIP & Russian interference 🧐 There’s another timeline where the Guardian supported me, doubled down on the investigation & I look 5 years younger ..

Ghost of yotei comes out in a week and I only just started the DLC of the first game.

It's a bit of a surprise to me, but there are still tickets available for performance.now(), the most important web performance conference of the year: perfnow.nl I'm booking my travel, and hope to see you in Amsterdam next month!

The kind of problems we see in #opensource with AI-slop PRs are prevalent in other sorts of work too

Tylenol parent company stock plunging, as they listen to the US President, eMD say on live TV to not take it.

Jesus Christ Daily Fail is pumping out the paracetamol thing on FB, not even sure why it is on my feed. This is definitely the worst timeline.

Seriously. A one-hour Party Political Broadcast. Followed at the top of the next hour with top story billing and a highlights package. Exactly how will this be "balanced" across their coverage? Where is Ofcom? Where is Nandy?

For 56 minutes Sky News and BBC News interrupted everything else and carried a Reform UK feed live, uninterrupted, unchallenged. The stream spluttered, froze, pixelated - dozens of times - still they stuck with it. FOR ONE HOUR. This is an editorial choice. No other party gets this coverage. ~AA

Oct 14 Firefox 144 will ship JS-powered view transitions with `startViewTransition`. 🎉 Of course, this is only the first step because we're all waiting for cross-document view transitions, too, but I'm still very happy about view transitions being on their way to work everywhere.

The arbiter of good taste

💯 “Client-side web development is perhaps best conceived of as influence-oriented programming. Once code has left the datacenter, all a web developer can do is send thoughts and prayers”

"Your Party" is done. We don't have time to mess around with this TERF-aligned clown car. Get behind the @greenparty.org.uk

UK politics basically are competing on how to be the worst party at this point.

We need this, it will make the web better.

Added an Interop 2026 Proposal for CSS Scroll State: github.com/web-platform... – please upvote! It would be nice to remove JavaScript requirement for various popular design patterns we're all using on the web (floaty navs, scroll shadows etc) cc: @nerdy.dev @bram.us #webperf #webplatform #webdev

As for CLS, @duffeh.bsky.social proposed it for Interop 2026. Vote it up here if you want that: github.com/web-platform... Lots of other great proposals to upvote too while you're there! Or even suggest a new one if there's something you want supported cross-browser — the process is working!
