Watching Dario Amodei and Sam Altman address the UN Security Council jointly to express the existential threat of AI. Trump is unwilling to listen to Anthropic and OpenAI. The UN must listen and must treat these threats much the same as we do nuclear weapons. They must be regulated and monitored.

One more call for feedback! Yeah, I know, I often ask for feedback but, think about it, the more you share, the better the feature. 💡Support low-quality image placeholders on the web! ➡️<img previewsrc="preview.avif" src="photo.avif"> ❓Would you use this? What capabilities do you need? Read more⬇️

Patrick - Blurry before beautiful: image previews for the web
Showing blurry previews while images are loading on the web is a very common pattern which we'd love to standardize at the browser level, so that all developers can use it with very little code and co...

I can tell you from very personal experience that we pay close attention to the results of the annual Interop efforts. If you are a developer who has been driven nuts by non-interoperable implementations in different browsers, please allow your voice to be heard.

Wrote a thing on the plane last night: The Web made the distribution of ideas universally accessible and effectively free, to anyone with the patience to embody them in words. Will it be allowed to do the same for ideas that can be embodied in code? aldenblog.io/posts/2026-0...

Ah yes... this. :-) It's very very nascent, but my team is looking into css-mixins.

Currently on my mind… If I “save time” by using AI to write code for me, but then I cannot submit a pull request for that code without evaluating it line by line (which feels right to me, I mean, it’s “my” code after all).

I love that Patrick is writing this new series. It's really difficult to know what improvements are happening in the Web Platform. Here is an authoritative source without a bunch of marketing sping - just developer content.

Here are some really cool examples of how to leverage Gap Decorations if you're a web dev... #css #w3c master.dev/blog/lets-pl...

Let’s Play With Gap Decorations!
The `rule` (and friends) CSS property allows us to draw markers (like borders) in the gaps between columns and rows (and flex items!)

It’s super awesome to have a president in very clear mental decline being the chief of a foreign war. Wow. This is GREAT!

Anyone else notice a dramatic increase in fake accounts on here lately? I keep getting hit with “hi!” And “do I know you?” Comments.

I would say that the problem with our government right now is he accurately states what is happening and uses the word “illegally” several times, yet there is not punishment and the crimes will continue. With no consequences, illegal behavior has no reason the stop. Relying on “morals” doesn’t work.

Spoiler for “No Good Deed” because I’m not happy. But there is NO WAY to explain the fact that the shell somehow ended up in the kitchen or in the pillow case.

Reposting because Vance is a freaking nitwit. Trump is in Florida golfing (again) and Vance is in Vermont. But this is really why: I grew up in Colorado and that sign that says “Vance skis in Jeans” hits hard. Like, the BEST sign of ever seen.

Want a great slogan for midterms? "If you FAFO and are struggling because of Trump policies, we understand. The Dems are here for you. Tell us how we can help you " You get the point. FAFO will be the theme. Be the solution.

Sometimes it’s nice to take a tour of your home town. Parked in Pioneer Square and Christa and I walked up the waterfront, up to Pike Place and then down 1st back to the car. It’s a really beautiful city.
