Even so, an automated quiz that could predict with high confidence that someone would fail an interview would be a big win, saving both interviewers and interviewees a lot of time.

Actually, there seems to not really be any legal issue with IQ testing job candidates (in the US), and plenty of companies do some kind of cognitive testing: http://econlog.econlib.org/archives/2013/07/three_b

Very interesting. According to this: http://furmancenter.org/files/publications/HVS_Rent_Stabiliz... , in Manhattan below 96th street 35% of rent-stabilized apartment dwellers moved in more than 20 years ago! (Vers

The subsidy shouldn't depend on the apartment, but it should depend on the renters. So you can explicitly set an income limit to exclude the $500k/yr family, but even if you don't, they don't get a bigger subsidy just be

This seems to explain the rules determining the rent you can charge for a vacant rent-stabilized apartment: http://www.nycrgb.org/html/guidelines/vacancy.html . Am I misunderstanding this page?

True, but you could do the same thing in any region of memory. The only thing that using "the stack" buys you is that there are a few special instructions to allocate / deallocate one machine word at a time (if you store the

The stack and the heap are both just regions of memory, so there's nothing inherently faster about using the stack. The difference is the memory management strategy: Usually, stack variables are all allocated at the beginning of a func

That's because banks do a lot of things other than FX trading. It's a much bigger chunk if you use a more relevant denominator: http://www.bloombergview.com/articles/2015-05-20/bank-fine-s...

Where do banks get the money that they loan out if not from deposits? Reserve requirements dictate what percentage of deposits banks have to keep on hand rather than loan out, and its inverse, the money multiplier, determines how much the m

I think your second paragraph has the effect backwards. If you spend $10, then you have $10 less, and someone else has $10 more, no change in money supply. If you put $10 in the bank, the bank loans out $9 of it, so you "have" $10

I'm deeply confused by this comment. The main thesis of that first link you posted is that it's way too hard for psychiatrists to prescribe a drug that treats heroin addiction.

1) You have to be careful with your definition of "local". The major reason that housing prices are so high is that many more people would like to be SF locals than currently can be. 2) Buying an investment home in SF is basically

Right, this is exactly what I meant by setting up the indirection yourself. The main difference seems to be that in Haskell, you have to write this code separately for each typeclass, and wrap/unwrap it manually. In Rust, you just chan

I don't think that's true. Dictionary-passing (or something equivalent) attaches the table of methods to the functions which take typeclass instances as arguments (with extra, hidden arguments), while Rust's Box<Trait>

The word "vector" just means an element of a vector space: a collection of "things" that you can add together and multiply by numbers. The vector space R^n is defined as the collection of all lists of n real numbers, so

I'm not sure if I'm disagreeing with you, but I really dislike the "collection of numbers that transforms in this way" definition of vectors, tensors, etc. I get why it's useful in calculations (that's why phys

It seems important to distinguish between actually voting, where everyone votes or has a chance to vote (at near-zero cost), and lobbying for individual legislation, where only the very highly-motivated "vote", at high cost. In th

I'm sure they check that the matrix doesn't contain a string, or that you're not mixing 32-bit and 64-bit floats, but checking user-defined units as in the article, where each row or column may have a different one seems almo

Are there dynamically-typed systems that actually do this? That check the units of matrix and vector elements at runtime without checking every single time you want to multiply two numbers together?
