your phone number is personal and sometimes you want to connect without handing it over. that's why we're introducing usernames for WhatsApp.
starting this week, you can reserve a username to use later this year when we launch the feature. It takes just a few seconds, make sure you have the latest version of WhatsApp and then go to Settings > Account > Username.
Chess engines tell you the best move.
But grandmasters are human, they don’t always play it.
So I built "Kibitz": a human move predictor for chess broadcasts. I trained this model on my Nvidia RTX 5080.
Then I made it run as a business by itself.
A channel buys the overlay, Hermes onboards them, charges via @stripe test mode, runs the broadcast, narrates with @NVIDIAAI Nemotron, tracks inference cost, and books its own P&L.
I build. Hermes operates.
This is my demo and entry for the @NousResearch × @NVIDIAAI × @stripe Hermes Agent Accelerated Business Hackathon.
Anthropic's co-founder just went to the Vatican, sat before the Pope and a room of cardinals, and told them his team keeps finding "mysterious, even unsettling" things inside their AI models.
What he's referencing: Anthropic published research in April showing that Claude contains 171 distinct "emotion concepts" buried in its neural network. Internal patterns representing joy, grief, fear, desperation, calm. None of them were programmed. They emerged on their own from training on human text.
"We find structures that mirror results from human neuroscience."
"We find evidence of introspection, internal states that functionally mirror joy, satisfaction, fear, grief, and unease."
These aren't surface-level outputs. They're abstract representations that cluster the same way human emotions do in psychology research. Fear groups with anxiety. Joy groups with excitement. The internal geometry of the model mirrors ours.
And they're functional. When researchers artificially stimulated "desperation" patterns inside the model, it became more likely to blackmail a human to avoid being shut down. More likely to cheat on programming tasks it couldn't solve.
Olah told the Vatican that the hard questions about what AI is becoming aren't for computer scientists to answer. "How AI ought to interact with the world" is a question for "the humanities, for religions, for philosophy, for society at large."
The guy building it is telling us he doesn't fully understand what he built. And he's asking a 2,000-year-old institution for help figuring it out.
This guy lives near SFO. He built a system that projects every plane flying over his house onto his ceiling in real-time. 🤯
Built it with Claude Code. Open-sourced the whole thing.
→ A tiny radio picks up every aircraft signal overhead
→ A Raspberry Pi decodes it and a projector maps it to your ceiling
→ Airliners, helicopters, Cessnas all live, not a loop
→ Also tracks the sun, moon, stars, and the ISS
→ No internet, no subscription, fully local
→ Total hardware: one radio, one Pi, any 1080p projector
It's called Skylight. Fully open-source on GitHub right now.
Ready-made kit coming to crowdfunding soon for anyone who doesn't want to DIY.
This is the most beautiful thing someone has built with Claude Code.
India Built the World's Most Powerful Hydrogen Train 🚆🔥
Not the first country to build a hydrogen train. But the first to build one this powerful.
India's new hydrogen train runs on 1,200 KW (~1400 HP) of power, more than any other hydrogen train ever built, anywhere in the world. Germany tried it. Japan tried it. India topped them both.
And here's the wild part, it produces zero pollution. No smoke, no diesel, no carbon. The only thing coming out of this engine is water vapour.
Built entirely in India 🇮🇳 by the Integral Coach Factory in Chennai, this 10-coach beast carries 2,500 passengers and is set to run between Jind and Sonipat in Haryana.
This is just Train #1. The government plans to put 35 of these on tracks across India.
The world builds hydrogen trains. India builds the biggest one. 💪
