There's actually an entire branch of math (galois theory) that spawned from the fact that it doesn't generalize! In particular, there's no formula for polynomials of degree 5 or hi…

There are a lot of similar failure modes in humans. Sometimes they're are used for good, like making drivers slow down: https://www.insider.com/optical-illusions-3d-crosswalk-drivi…

I don't know the details but I heard the original codebase was javascript but they used an automated script to convert it to coffeescript as an hack week project! That's some serio…

This is probably premature optimization, but what's the performance cost of updating a deeply nested field inside a jsonb? What about indexing it? (compared to storing in some norm…

Uber/airbnb/lyft were considered in the same tier as facebook/google before corona. With google also slowing hiring, are the engineers laid off all going to be absorbed by facebook…

I have not read it myself but the answer can probably be found in the book "The Science of Interstellar" [1] Kip Thorne, a Nobel prize-winning physicist, worked as the science advi…

Isn't that the wrong direction for the optimization? I would assume you would want to compile adding two numbers into shifting by one, not the other way around. (I know nothing abo…

Even with worst-case scenario of bias, this is still extremely good news. My worry was always with super spreaders who refuse to isolate but the data is suggesting that those sprea…

Use a profile picture that's already public and have been crawled a bajillion times. E.g. https://twitter.com/jbverschoor/photo

Hmm is the argument that you can generate infinite money otherwise? I think the two directions only look superficially the same because externalities and labor isn't taken into acc…

One of my colleagues loathes competitive programmers and picks much harder problems for them. His grumpy rationale is that they shouldn't have it any easier just because they do in…

Most algebraic structures are best understood by which axioms it satisfies. For example basically every subset of axioms of an abelian group is useful enough to have a name. Wiki h…

Does anyone else think NY called their peak prematurely? It seems like there's some periodicity in the data and there's always a slight two day drop every 7 days. This makes sense …

An unexpected application of feistel network is for creating neural networks that are invertible! https://arxiv.org/abs/1802.07088

To put this in perspective, NYC is projected to run out of ventilators early next week[1]. That means if you catch it now and need ICU, there's no medical equipment to save you. Wh…

I lived on $200/month in SF (single person) and I definitely didn't "eat like an actual human being". But the problem was definitely me and not that it wasn't possible. Usually in …

It's definitely not an unpopular opinion, especially on HN. Pre-corona I was probably a crazier privacy nut than most so I completely understand where you're coming from. But right…

Even if you focus on pure tech problems, startups seems to be failing us in the US. Other countries have scaled out thermal imaging for fever detection, face tracking for contact t…

Your link is already a great resource, thanks for that! I didn't know Susan Fowler was a physics major at UPenn. The tl;dr; seems to be get "University Physics with Modern Physics"…
