If you had no chance to learn from Tim Roughgarden, please do. The clarity of his lectures is top noch. I saw Technion Univ on knees.

jane street, two sigma, man group put their actual code on github 22 repos from firms running $200 billion combined - all public, all free nobody's talking about this because nobody thought to check what's in those repos isn't just tooling - it's their mental model these firms don't ask "will price go up?" they model markets as adversarial games - every participant simultaneously optimizing against every other that's why their signals hold - retail's don't two sigma's repo covers how they structure and clean data at scale man group's work spans signal generation, portfolio construction, factor models jane street's tools teach probability and microstructure exactly how their quants think this is game theory applied to markets - nash equilibria, auction dynamics, opponent modeling not chart patterns or indicator crossovers code is free, frameworks in public repos, math in every probability textbook Bookmark before it gets buried retail paid for courses on same stuff these firms gave away information gap was never intelligence, just knowing where to look

Guys, no evidence of $ZEC exploit Its just panic 🤣 Taylor Hornby is right. Imagine someone else did this. $ZEC is fine.

Thx god I was blocked by @zooko
Very disturbing for $ZEC holders yikes

Xi Yin just left Harvard for OpenAI. String theorist. Youngest full professor in Harvard history. His words: "AI gives me 100x speedup. Weeks of output would take me 10 years." Then: "I don't believe there's any human intellectual ability AI cannot replicate." The man who said that is the one who would know. #DINQ #AI #OpenAI

In 1963, mathematician Stanislaw Ulam got bored during a meeting and started doodling a grid spiral of sequential numbers. By highlighting only the primes, he uncovered what remains one of the most mesmerising visual mysteries in number theory: the Ulam Spiral.

🚨 SCIENTISTS JUST DISCOVERED “NARWHAL WAVES” THAT CAN TRAP LIGHT BEYOND KNOWN LIMITS. And the physics behind them looks almost impossible. Researchers have found a strange new type of wave behavior where light becomes trapped inside ultra-thin structures in ways that completely defy normal diffraction limits the rules that usually force light to spread out the tighter you try to focus it. They’re called “narwhal waves” because of the sharp, horn-like energy spikes they create. Why this matters: Normally, the smaller you try to squeeze light, the harder it becomes to control. But these new waves can: Squeeze light into nanoscale regions Amplify electromagnetic energy dramatically Guide photons with extreme precision Potentially unlock next-generation photonic computing That means smaller, faster lasers, ultra-efficient optical chips, highly sensitive quantum sensors, and entirely new forms of light-based technology. But the deeper implication is even stranger: At extreme scales, light stops behaving like a smooth, spreading wave… and starts forming highly localized, geometric structures almost like temporary “knots” of trapped energy woven into space itself. The boundary between waves, particles, and physical structure keeps getting blurrier. What else is still hidden inside light that we haven’t discovered yet?

Nice. I did not know that LLM opt engines are uncommon. BTW, a new rules might be created on fly to enrich a solution space.
A Fields Medal–winning mathematician once called one of Marijn Heule’s proofs “the most disgusting proof ever.” But his methods go beyond what any human can do. quantamagazine.org/to-have-m…

The timeline in this image tracks the evolution from linear physics to exponential computation. It highlights how we moved from foundational variables like the Schrödinger equation (1926) to complex operations like Shor’s factoring algorithm (1994). We are currently transitioning from NISQ (Noisy Intermediate-Scale Quantum) devices to algorithmic fault tolerance, scaling the probability of error toward zero.

In his 1964 book Summa Technologiae, Stanisław Lem argued that humanity will hit an “information barrier” — a point where the volume and fragmentation of information exceed humanity’s ability to filter, interpret, and integrate it into a coherent body of knowledge.

Excited to co-found Recursive (@recursive_si) with an exceptional team in London and SF to create AI that experiments on how to safely improve itself, turning compute into knowledge that accumulates in an open-ended process of endless, automated scientific discoveries.

we ACTUALLY got the oppressor mk2 before GTA 6. Polish engineer Tomasz Patan built the Volonaut Airbike. it hits 124 mph, runs on jet propulsion, has no propellers, and weighs less than your dog. pretty fucking sick.

Frontier models are effectively knocking down my research agenda, problem after problem. This is a *new* development: this was inconceivable to me as recently as last December. The bottleneck is verification---it takes me days, sometimes just hours, to generate a proof, but weeks for me and my coauthors to verify the content.

The Moon Landing Conspiracy Ends with India. For decades, skeptics have claimed the Apollo 11 landing in 1969 was staged. But an independent space agency has delivered undeniable proof.India’s Chandrayaan-2 orbiter, flying at about 100 km above the lunar surface, passed over the Sea of Tranquility and captured high-resolution images of the exact landing site.Right there, inside the marked circle, sits the descent stage of the Lunar Module Eagle — the very hardware Neil Armstrong and Buzz Aldrin left behind on July 20, 1969.This isn’t NASA imagery. It’s ISRO — captured by Indian scientists with their own spacecraft and their own camera (the Orbiter High-Resolution Camera).The hardware is still exactly where history says it should be, casting a long shadow across the lunar dust more than 55 years later.Third-party confirmation from a completely independent nation. No collaboration needed. Just clear orbital evidence.The Moon landings happened. The proof keeps piling up — now from another country that has reached the Moon with its own technology.Case closed.
Community note
While the Apollo 11 landing is real and has been imaged by Chandrayaan-2, the photo in this post is not from that mission. Real images show the site as small features, not a detailed lander in a crater. en.wikipedia.org/wiki/Third-par… lroc.asu.edu/posts/110

When you start a chess game, you have 20 possible moves available. After the first full move (White then Black), there are already over 400 possible positions. By the third move, that number jumps to around 8,900, and after the fourth it reaches nearly 200,000. By the time you get to move #40, the total number of possible games explodes to roughly 10⁴⁰, a number comparable to the total number of atoms in the observable universe.

🇵🇱 Bro turned his Warsaw apartment into a stage for Poland's biggest music stars to raise ~$70MIL for the Cancer Fighters Foundation was streaming for 9-days livestream reached 1.64MIL simultaneous viewers
🇵🇱 Polish streamer, Piotr "Łatwogang" Garkowski broke world record for the largest amount raised during a single charity livestream by streaming continuously for 9 days from his apartment He concluded the broadcast on April 26, raising over 251.7MIL złoty ($69MIL) for the Cancer Fighters Foundation "Every donation goes directly to helping young cancer patients, with all expenses fully documented for transparency." — highlighted Streamers are also heroes!
