Consumers in California pay around 1 penny per gallon of water. Farmers pay an average of $70 per "acre-foot" which is around 325000 gallons. So farmers get their water for roughly 30x cheaper than consumers. Agriculture is also a

In 2005 Google search got into a sticky spot, where they were completely unable to deploy new versions of the search engine from the master branch of the code for a while, because there were performance regressions that nobody could find. D

If you learn all this and you can't solve LFU cache in 45 minutes, go back and study the parts about heapsort, red-black trees, and B trees. If you learn all this and you can't solve "integer to words", go back and do so

My advice is to get good at leetcode "the right way". Don't memorize problems. Instead, learn the underlying algorithms. Learn heapsort, quicksort, how to find medians, how to derandomize and calculate the running time of the

It's such a weird "bet", though. Pay $1, get back $1 if you win, get back $0 if you lose.

Who else can it be besides Intel? I don't think it even needs to be "domestic", per se, it just needs to be in a country that isn't extremely likely to be invaded by China.

The big question in semiconductors is what will happen to the China-Taiwan situation. China has repeatedly stated that they intend to reunify with Taiwan by 2049 for the 100th anniversary of their communist party. I think they will probably

Well, it isn't really that hard even for nearby stars. You need to be sure to get an updated version of the library like once per decade. I think once you're further away than 100 or so light years the star movement is no longer a

Even now we've adopted encryption, which appears sufficiently random. When you pick up an encrypted signal, it's still obvious there's a signal there. Radio telescopes will pick up cell phone signals, for example; that&#x27

No, I just mean you design your system expecting the data from machine 1462 to get analyzed at some point, but that machine belongs to some random person who uninstalled your software without you knowing about it, so you never get back an a

For what it's worth, the architecture for seti@home doesn't make much sense any more in the modern era for most types of data processing. It's simply too slow and error-prone to transfer large amounts of data between user mac

You can generate arbitrary problems easily enough The problem with generating arbitrary math problems is that you can generate an infinite number of boring, pointless problems. For example, prove that there is a solution to the system of

Personally, I think a schedule of 2 days in the office and 3 days wherever is pretty nice. You can regularly have important team meetings and 1-1s in person, you can get to know your coworkers face-to-face, but you can skip most of your com

I think the Northern California crows are larger than their east coast counterparts, so I agree, it is harder to tell them apart by size here. Ravens are larger still, though. If you see one in San Francisco, it's probably a crow. Occa

Personally, when I see crows or ravens flying I often can't see their tail and I often can't quite tell how large they are. I find it easier to distinguish their call, a crow sounds like "caw" and a raven sounds like &qu

I find it odd though that people make so much less compared to their US counterparts. Does anyone know why that is? It's just supply and demand. When I was working at Facebook they figured out what salary ranges they should pay in ea
