I'm happy to announce the launch of Acorn, a new theorem prover that includes an integrated AI. Theorem provers let you write mathematical proofs that are rigorously verified. But they are notoriously difficult to use. Acorn makes it easier, by using AI to fill in the details.
In the 90's, before the rise of Google, we had Metacrawler. It ran your search on ten different search engines, and you could decide which was the best. I want this for coding agents. Let me send the same request to Claude, Codex, etc, choose the best PR, and ditch the rest.
I learned AI in college 25 years ago, and 95% of it is no longer relevant. Surprisingly, most colleges haven't updated their intro AI curriculum! This new intro AI course from CMU looks great to me. It's focusing on the right thing, and other colleges should copy their lead.
I'm teaching a new "Intro to Modern AI" course at CMU this Spring: modernaicourse.org. It's an early-undergrad course on how to build a chatbot from scratch (well, from PyTorch). The course name has bothered some people – "AI" usually means something much broader in academic…
TIL that Australia also changes its clocks around the same time, but they change in the opposite direction! Makes sense if you think about it, but it does make scheduling annoying…
If someone is leading a large organization in a way that seems completely insane to you, and yet that organization achieved things that nobody else has, perhaps there is a method to the madness.
It's funny what algorithmic problems the LLMs are good and bad at. With 20 simple lines of custom application-specific behavior, the LLM often introduces bugs. With a complicated 200 line implementation of a known algorithm, the LLM quickly makes perfect tweaks.
I'm interested in learning more about dependent type systems. What's a good next step after Pierce's "Types and Programming Languages". Any recommendations?
I hate almost all embedded advertising, but by the time I get to these, I'm leaning forward and paying attention
TIL that until 1994, it was forbidden for a bank to open a branch in another state en.wikipedia.org/wiki/McFadden_…
For problems that are slightly too hard for the LLM agents, I've been having success insisting that they first find a minimal reproduction, then write a narrow unit test, and only then fix it. Like micromanaging an overconfident junior engineer....
I’m unexpectedly appreciating the new Yudkowsky book. Not that I agree with his emotional stance, but the scenario seems not obviously impossible and also un-disprovable, so perhaps we will just need to dimly think about such things forever now, so we might as well get started.
Anecdotally, sentiment rapidly changing from old: "new grads are useless in the age of AI" new: "I'd rather hire a new grad who is good with AI than someone with experience who doesn't use AI" I don't really know how to interview for it though....
Historians two thousand years from now: "Everything known about Homer Simpson is conjectural, but the best evidence suggests that he was a series of writers, rather than an individual."
I’m not sure what will happen. According to levels.fyi, a Facebook E5 (senior engineer) already makes about $450k in California and $320k in Vancouver. An extra 100k isn’t nothing, but still. Is this going to stop H1Bs, or just shift the quota to the tech giants?
Trump signs an EO on H-1Bs raising "the fee that companies pay to sponsor H1-B applicants to $100,000"
It would be more secure if 2FA codes were difficult for English speakers to describe or pronounce. Like: ژ ऊ ʃ Ҕ You could select these from a dropdown pretty easily, but scammers often rely on you reading them the code.
