Like food, right? If people stopped selling you food you would die, so surely they can charge extortionate rates for it. Of course, there are competitive markets for both food and insulin in the US. Quoting from a letter to the WSJ yesterda

A per-share valuation would be more appropriate, I think. Otherwise someone shorting could lose even if WeWork raised a down round.

User space shouldn't care about implementation details like storage primary keys. I don't think copies are difficult either, but I guess some other storage scheme could make them simpler.

It sounds like this is a pretty easy problem to solve if files aren't identified by their names. If a file just has a name (and a parent, and a bunch of tags...) then tags are trivially stable when moves/renames/writes happ

Eh, no place is perfect. I feel a bit bad for griping about it, I heard the bad news recently and I guess it's still a little raw. On the upside, it's probably healthier to find a hobby further away from a computer screen...

Sure, but then you need to make sure they never get out of sync. If you add a "remove order" action you need to remember to decrease the sum. Really, if we're smart and diligent enough to be able to correctly update all the d

With this definition, different parts of the input might be "meaningful" for two algorithms that solve the same problem. This makes the size of the "meaningful" part of the input ill suited for comparing efficiency. (It

I think it would be tough to find a suitable definition of "meaningful". When searching for an element in an ordered list, how many items are meaningful? One if it's present, zero otherwise? Always log(n)? Always n? If "

That holds for houses, but most inflation measures index housing on rent , not house price, possibly to account for the sensitivity of house prices to interest rates. From another angle, look at consumer goods a year ago compared to today.

"Exponential" is often colloquial short-hand for EXPTIME, which is closed under some useful operations (because there's an "any polynomial" in the exponent.) For one thing, it's robust to reasonable changes o

It's also a robust distinction because polymomials are closed under addition, multiplication and composition. Converting an algorithm from a Turing machine to a random-access model will often give you a polynomial speedup, but not an e
