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 higher. https://en.wikipedia.org

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... But other times they cause crashes

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 serious long term damage they did in that one week. Edi

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 normalized form or in other popular document stores)

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 advisor for Interstellar so the hollywood bs is pretty

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 about hardware, it just intuitively seems like moving a bu

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 spreaders will still soon achieve herd immunity among themselves.

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 account?

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 interview problems as a sport. Usually the ICPC world fin

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 has a really nice table: Semigroupoid Small Category Groupoid

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 since many people are still working mon-fri in the

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. Whether government mandated or not, people are gonna stay

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 now our privacy is not worth more than our parent

The NY governor in your video cited that 40-60% of people are going to get it (20 min mark) and the same thing was said by CA governor a couple days ago too (56%): https://news.ycombinator.com/item?id=22633570 So it seems l

It would be so useful if I got a notification if I happen to have crossed paths with a person who later turned out to be infected so I can get tested too. This will preempt so many asymptotic transmissions. Such apps are already deployed in
