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.
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?
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 bunch of bits over by 1 should be faster than dealing with xor and carries)
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. As long as the rest of the society behaves we will still hit zero cases relatively quickly.
(which wasn't always clear to me before since I initially predicted that this will take years to work out)
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 finalist types will still ace it since he's too dunning-kruger to judge beyond his own skill level.
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:
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 city.
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 the fuck home because they don't want themselves or their parents to die in a hallway.
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 those financial conditions you also know your time is better spent elsewhere. An extra hour per day practicing for interviews is much better use of your time than cooking. So you do the most efficient thing possible, which is just throw whatever is cheapest per lb into a slow cooker and eat it for the rest of the week. Most stuff is pretty disgusting after a few days in the fridge.
It's probably possible do meal prep cheap/fast/delicious, but I definitely never learned how. Tips appreciated!
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 parents' and grandparents' lives. You ought to re-run your moral calculations with the current state of the world in mind. There are literally millions of lives at stake.
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 tracing, and have mobile apps that can warn people where a previous infected patient have visited before. I have yet to see any of that here.
In particular, there's no formula for polynomials of degree 5 or higher.
