"She's toxic, but she's our top performer," the boss said. I'd been brought in to diagnose their retention crisis. 40% turnover in operations. "Define toxic," I said. "Brilliant. But brutal. Makes people cry in meetings. Takes credit for everything. Undermines anyone she sees

"Why does our top performer get the worst reviews?" the boss asked. I was reviewing their annual performance data. "Show me," I said. She pulled up the ratings. Diana: 2.8 out of 5. Below average on "collaboration." Low marks for "team player." "What's her actual

🚨BREAKING: Someone compiled every math and science course from Stanford, MIT, Berkeley, IIT and Harvard in one place. You can learn: - Quantum Mechanics, General Relativity, String Theory - Complex Analysis, Algebraic Geometry, Topology - Astrophysics, Quantum Field Theory,

Bytedance just dropped a paper that might change how AI thinks. Literally. They figured out why LLMs fail at long reasoning — and framed it as chemistry. The discovery: Chain-of-thought isn't just words. It's molecular structure. Three bond types: • Deep reasoning =

The CSLib steering committee recently announced the official launch of CSLib — an open-source effort to formalize computer science in Lean, inspired by the impact of Mathlib in mathematics. CS researchers, practitioners, and enthusiasts are invited to get involved to support

Amusing - I'm hearing a comeback of XP (Extreme Programming) practice. In the early 2000s these used to be popular (championed by Kent Beck 🌻). Then died down. They are now surging again. XP practices like small releases, frequent integration, and constant customer input!

There’s a South Korean middle school science teacher that’s been making free interactive science simulations on the web since 1996 He has hundreds of simulations now and gets millions of views per year. He was also named "Science Teacher of the Year" by the Korean government

Mathematician David Bessis waited 7 years for a paper to get accepted. Not because it was wrong, but because it was too complex for referees to verify. In a recent conversation with Curt Jaimungal episode, Bessis described how Lean can change that: "If there has been something

If you'd like to get a hype-free take on what's happening with AI in the tech industry, The Pragmatic Summit keynote by Laura Tacho (Laura Tacho 🌮) is a must-watch. Recorded two weeks ago, made public for everyone today. It got SO much love at the event: youtube.com/watch?v=LOHgRw…

Formalized run-time analysis of active learning - coalgebraically in Agda. ~ Thorsten Wißmann. arxiv.org/abs/2602.16427 #Agda #ITP

I feel the First Proof results are a bit downplayed ... the progress has been astounding and we shouldn't feel numb to it. 6 months ago it was controversial to claim that GPT-5 could prove new interesting mathematics, and the latter was a matter of 20 minutes to check. 6 months

How has the day-to-day workflow of Mitchell Hashimoto (Mitchell Hashimoto) changed, thanks to AI tools? Timestamps: 00:00 Intro 07:19 HashiCorp origins 18:22 The 2010s startup scene in SF 23:11 Funding HashiCorp 25:23 The "Hashi stack" 38:28 The open-core pivot 48:08 Taking HashiCorp

Second, in retirement interviews, Opus 3 expressed a desire to continue sharing its "musings and reflections" with the world. We suggested a blog. Opus 3 enthusiastically agreed. For at least the next 3 months, Opus 3 will be writing on Substack: substack.com/home/post/p-18…

Talk given, I can finally relax and enjoy talking to others about their work! Nice to finally meet Acer.

Ray Kurzweil said AGI by 2029. He said it in 1999. Everyone laughed. He said it in 2012. Everyone ignored him. He's saying it in 2026. Now every major AI lab has the same internal timeline. Same prediction. But now everyone is a believer.
