C++ dev and ex-FAANG staff engineer with 30+yrs of experience was stuck on a bug for ~200hrs over 4 years. Claude Opus 4 solved it, and was the only model that could.

What heuristics reliably help you understand things much more deeply? I've read most of o3’s suggestions below and they're fine resources. But I can't help but feel the question “How to understand things *much* more deeply" is very, very undersupplied with good answers! All the

This is an incredible progress story An aggressive type of cancer (Philadelphia chromosome–positive acute lymphoblastic leukemia) used to carry a dismal prognosis, with 50% of patients dying in a year New therapies have transformed it to a cancer that most people are cured of

Math: My results are theorems proven through formal logic Physics: My “laws” are empirically observed regularities, measured to several decimal places Economics: I will count people, raise that to a fractional power, multiply by dollars raised to another fractional power, and

Trying, once again, to actually understand what 'free energy' means - would love any help/pointers! - if it were renamed, what do you think it should be called instead? - what are your favorite thought experiments / toys that involve free energy? - what isn't true about it, that

SCOTUS Seven County decision is out! TLDR: It’s a big deal, it limits NEPA, it’s better than expected, BUT… there’s still uncertainty. The ruling does two things: - Calls for giving agencies more discretion - Sets clear limits on what EIS reviews have to consider 🧵(1/14)

New: The last two weeks have been potentially devastating to America's ability to attract top talent. Between visa bans, revocations, and the possibility of cancelling international graduates' ability to work after school, our talent retention problem is about to get worse. 1/7

Thanks for having me on! Some stuff we covered: - Bell Labs-style systems engineers in new science orgs - How I'd give away $100M, inspired by early Rockefeller Foundation - BBNs at early ARPA, and why I joined RenPhil to build more of them - & tons of R&D history anecdotes
