AI IS SO GOOOOD!!!
Screenshot of a Dell AI Virtual Assistant shitting the bed when asked a simple question: Compare the XPS 13-inch with the XPS 14-inch, where it responds that it couldn't locate a XPS 13-inch model. The model is in the screenshot. I'm on that model's page.

Mathematicians at OpenAI announced that a group of 10,000 autonomous AI agents under their direction proved that the Navier-Stokes equations can “blow up,” thus solving one of the six remaining Millennium Prize Problems. The result is not without controversy. www.quantamagazine.org/ai-has-solve...

Mathematicians at OpenAI showed that the Navier-Stokes equations, which describe how fluids flow, can sometimes “blow up.” But the massive result is not without controversy.

@budgetcommitteepod.bsky.social hi there! I found your pod from the guest episode on Have You Heard. I went to your LinkTree to find the submission form you mentioned but only found one for the Chicago event. Anyway, I'd love for you to look into Portland Public School's "Rightsizing" effort.

Even though I'm a big fan of Postgres, its lack of loose index scan is frustrating.. The workaround is a recursive query that effectively acts as a loop, which is even more bizarre. Check out this new blog post about the performance issue with Postgres SELECT DISTINCT: www.dbos.dev/blog/postgre...

Postgres SELECT DISTINCT performs surprisingly poorly. We explain why and how we mitigated it.

I wonder how Erdős would feel about this. Would he care that a human didn't write the proof? Would he think any of these machine-generated proofs are from "The Book?"

This is an excellent suggestion (and something we've been doing for any deep changes). Typing out changes loads context into your mind in a way you'll never get from reading in a code review.

My coauthor Dave Perkinson made this diagram to explain the binomial theorem and I think it's the perfect distillation. Here's our draft book, Discrete Structures, if you want more: kyleormsby.github.io/files/113spr... 🧮
A color-coded binary tree displaying how to expand (x+y)^3. There are 8=2^3 terms on the bottom, and by putting them in "alphabetical order" and grouping like terms, you see that (x+y)^3 = x^3 + 3x^2y + 3xy^2 + y^3.
