Meanwhile, Tesla stockholders voted to pay Elon Musk approximately $2 million per child he’s killed thus far.
One analytical model shows that, as of November 5th, the dismantling of U.S.A.I.D. has already caused the deaths of 600,000 people, two-thirds of them children. https://newyorkermag.visitlink.me/jUzNSc

Looks like X is juicing web visit numbers by opening a browser WebView in the background whether the user visits the link or not.
They've re-invented pop-under fraud (allegedly).

![Tell HN: X is opening any tweet link in a webview whether you press it or not
247 points by stillatit 10 hours ago | hide | past | favorite | 200 comments
Just saw the CEO of Substack celebrating traffic from X/Twitter shooting up thinking they stopped suppressing tweets with links[0]. Actually, this traffic is because now any time you open a tweet with a link, the in-app webview loads in the background, and displays when you press the link.
I run an ecom store that gets a lot of its customers from Twitter. I was also shocked to see my traffic double or triple overnight and thought the algorithm had blessed me and my business. Soon realized what was actually happening. Thought other traffic-monitors might appreciate this explanation.
Meanwhile Nikita Bier is pretending they never suppressed tweets with links to begin with, offering the alternative explanation: "a common complaint is that posts with links tend to get lower reach. This is because the web browser covers the post and people forget to Like or Reply. So X doesn't get a clear signal whether the content is any good"[1]. A bit of a rewriting of history since Elon and his mom both tweeted about how it wasn't fair to use his platform to promote other links/platforms, even banning people who shared profiles of other social networks (including Paul Graham for a period). They suppressed all links shortly after.

So I'm reviewing a PR from a colleague that was written for like 95% by AI, and while it might have made his job easier, it's making mine a lot harder because it's riddled with mistakes and issues that I have to now fix, and I feel like I have to thoroughly check every single line of code twice

Let's talk about why batched transitions are usually better.
Here is a cart where changing the quantity updates the total. The item subtotal and cart total update async. Take a second to think of what should happen if you increase the quantity:

⚓️ New Article: The quest for the perfect progressively enhanced dropdown menu
The quest for the perfect progressively enhanced dropdown menu
I’m currently working on the navigation patterns for Kelp, my UI library for people who love HTML.
The bane of my existence right now is trying to figure out the right way to implement subnav/dropdown menus that work for everyone.
Today, I want to talk about why this is still such a difficult thing to accomplish in 2025. Let’s dig in!
The web is for everyone If you’re not sure what I mean by dropdown menu (it can mean many things to many people), I’m specifically referring here to a navigation menu (usually in the header) where one item in the list has an expand/collapse section with addition links.

Are we really headed towards auto generated user interfaces? What does that world even look like?
I understand the flexibility of prompt based interfaces, but are prompts the universal interface to every problem? Wouldn't feature discovery still be a challenge like we see with hidden menu options?
