Man, lemme tell ya, Hacker News was buzzing yesterday! I was scrolling through and caught a few interesting threads. Quick rundown for ya:

Browser Fingerprinting - The Creepy Tracker Stuff

First up, there was this article about browser fingerprinting. You know, how websites track you even without cookies, just by looking at your browser setup? The article called it a "privacy nightmare," and honestly, it sounds pretty bad. People in the comments were saying how the whole ad system is kinda broken anyway, and doesn't even help content creators that much. Someone mentioned an old paywall service called Blendle that failed, so it's not an easy fix.

AI Agents - Still Not That Smart?

Then there was a big one about AI agents still being hard to design. Basically, the guy writing it was saying all the hype around AI making super-smart agents that can do anything is a bit much. People in the comments kinda agreed, saying LLMs are great for simple stuff like formatting text (like JSON) but totally fall apart for more complex tasks or actually figuring things out. It’s like, they’re good at mimicking, but not really *doing* yet, if that makes sense.

Superman Comic Sells for CRAZY Money

Get this, an original Superman comic just became the most expensive comic ever sold! Super wild, right? It just shows you how much nostalgia and rarity can drive prices up. The comments section had some folks talking about how collecting anything – comics, baseball cards, retro games – can quickly become an obsessive rabbit hole where value kinda feeds itself. Pretty cool, but also kinda crazy.

New Mexico Goes Big with Free Child Care

Okay, this one's a big deal: New Mexico just became the first U.S. state to offer free child care for everyone! Like, for ALL kids. That's a huge step. The comments were, as you can imagine, all over the place, talking about public healthcare, tax rates (some even comparing it to New Zealand), and even universal basic income. Definitely got people thinking about social programs.

China's Nuclear Energy Breakthrough

Sci-fi sounding stuff next: China apparently hit an energy milestone by "breeding" uranium from thorium. Thorium is way more common than uranium, and the cool part is they can apparently use it to eat up existing nuclear waste rods and turn that into more energy. So it's like, more fuel AND less waste. One comment said nuclear waste is actually more of a "political problem" than a "technical" one, which is an interesting take.

Show HN: Forty.News - News from 40 Years Ago!

Someone built a really cool website for a "Show HN" called Forty.News. It shows you daily news, but on a 40-year delay. So you're reading headlines from exactly 40 years ago today. Super neat concept to see what was big back then! The hilarious part, though, is that the top comments on HN somehow managed to devolve into a debate about current political events, totally ignoring the actual project. Classic HN, right?

Smartphones and Kids' Mental Health

And finally, a study came out saying kids who get smartphones before age 13 have worse mental health outcomes. Not super surprising, but still an important reminder. People in the comments were debating if it's the phone itself or just social media, and some parents talked about using "dumb phones" or super strict app blocking. Others pointed out that kids *without* phones these days might be the "edge cases," which is also food for thought.
