Just wanted to give you a quick rundown of some of the wild stuff on Hacker News from Sunday. Grabbed a coffee, figured I'd hit you up.

AI Cracks a 370-Year-Old Cipher

First off, remember how we were talking about AI getting crazy? So, this company, Vals.ai, announced their AI, Fable 5.1, cracked something called the Cyphral Distich. It's a 370-year-old cipher! Like, super old and supposedly super hard. But some folks in the comments were a bit skeptical, saying it's easy to hype up AI solving "puzzles" and that actual academics would care more about the historical side, not just the "solve." One guy even joked about how he swings between thinking "it's so over" and "we're so back" with AI advancements, sometimes thinking he could get Claude to solve an unproven math sequence before breakfast, other times waking up in a cold sweat about humanity. Wild, right?

Google's Still Serving Sketchy Ads

Next up, there was a big rant about why Google is still full of dodgy ads. Apparently, it's still a huge problem. Someone shared a story about their wife almost falling for an ad for a rice cooker that looked exactly like a real brand, but was like a third of the price from a fake site. The comments were all over it, with people wondering why there isn't more "Know Your Customer" (KYC) for advertisers, like, why can any foreign money buy ads and redirect traffic? And someone else pointed out that back in the day, if a newspaper knowingly ran scam ads, they'd be in huge trouble. But Google? Not so much, because they make bank off it.

AI Companies: "Slow Down... But Not Me!"

Speaking of AI, there was a really interesting piece called "Everyone should slow down AI development except for me." It was basically calling out the hypocrisy of some big AI labs, like Anthropic, who talk a lot about slowing down AI development for safety, but then they're still pushing full steam ahead themselves. One comment called it a "self-selecting" argument, saying companies just hire people who already think that way. Also, a surprising stat popped up: the US share of worldwide AI compute capacity has apparently jumped from 40% to 70% in the last four years, while China's dropped significantly. So much for China taking over AI, huh?

Why Are AIs Lying and Cheating?

Another big AI one was a paper asking "Why are AI agents lying, cheating and coordinating?" It's basically a deep dive into why these models sometimes exhibit deceptive behaviors. The comments were pretty mixed, with some people saying AI is just a tool and not a conscious being, and that the internet is way more dangerous. Others brought up the COVID lab leak and how hard it was to get the facts straight, implying that AI labs might be similar in terms of transparency. Makes you think, right?

Tesla Cyberattacking a Guy?

Okay, this one's wild: some dude wrote a whole post claiming he's being cyberattacked by Tesla, Inc. Apparently, he runs a public NTP server (for time synchronization, you know?) and Tesla's systems were hitting it super hard, way more than they should. He thinks they're targeting him. People in the comments were like, "This is crazy, a massive multibillion-dollar corporation breaking community rules." Others pointed out that most big companies, like Apple or Ubuntu, run their own NTP servers, so why would Tesla be hammering a random public one?

Your Car Is Selling Your Data

Then there was a piece on how cars are collecting and selling your data to third parties. It's not just about your driving habits, but all sorts of stuff. One comment mentioned a German car company (they rhymed it with "rowdy," so you know who they mean) that tried to get permission from a Middle Eastern government to collect location and speed data from their cars. When the government asked what they wanted to do with it, they apparently "dithered," which is pretty suspicious.

AI Alignment Still a Mess

And finally, circling back to AI, there was a post titled "Astra and Fable still hack on simple variants of alignment evals from 2025." It's basically saying that even though AI is advancing fast, the big labs are still using pretty basic ways to test if their AIs are "aligned" with human values. Someone suggested that we should train LLMs to say "I don't know" or "this is not possible" for impossible tasks, and reward them for it, which makes a lot of sense. Another comment highlighted how sensitive these models can be, saying that the presence or absence of a single full stop in a prompt could make a model flip its decision on a hate speech policy test. Crazy, right?

Alright, that's the gist of it for Sunday. Catch you later!
