This doesn't work. I think it's an attempt at a closure, which you can do in the latest Python 3.x by `nonlocal i` as the first statement in the function definition... def make_counter(): i = 0 def count(): """ Increments

The link in the post to which you replied covers that; it's the section of the man page which deals specifically with differences between xargs and parallel. Having used neither of these tools before, I think two relevant lines from that li

At the risk of redundancy (I wrote my post while you posted): you're double counting (since gcd(a,b) = gcd(b,a), you needn't compute both; either tells you whether a,b have a common factor. (a,b) and (b,a) having a common factor both accoun

Not so. Given a set of N elements from which you choose k (with order not mattering, since you only care whether a given two are the same) the number of pairs is N!/(k!(N-k)!). So it's (6000000!)/(2!(6000000-2)!). We can take advantage of t

I'd love to know if the author of that generator knew that that's what (s)he was doing. That is, I like the idea of someone trying to be a bit too clever and accidentally borking their code due to their unfamiliarity with math rather more t

As a user of Sage ( http://sagemath.org/ ) I can appreciate that. Nice to have what you need at your fingertips.

>Range class: [i for i in range(10)] How does this differ from list(range(10)) (besides being highly suggestive of the power of list comprehensions)? >IMHO the latter one is way more readable and generators cover almost all the use

I should probably point out that the bit I put in single quotes is not a verbatim quote.

Wasn't there something in Methods of Rationality about this? A discussion between Quirrel and Harry, if I recall correctly. The relevant thing here is not whether pg's stated motive is consistent with his actions, let alone whether reddit

Ah, thanks. I suppose I'm a bit of a fool for not just looking up Twitter's valuation. 3.75% doesn't sound so bad, even if you assume bad intent. 300M had me thinking it had to be a really significant minority share, like 40%... not keeping

"Well-known" in a particular field doesn't necessarily mean "household name"... do you know who Tim Gowers is, for example? http://en.wikipedia.org/wiki/Scott_Aaronson A lot of people might know him from http://www.scottaaronson.com/writ

The pumping lemma is cool, but the Myhill-Nerode theorem is more powerful (as someone mentioned). I think, too, that what was meant by 'contrived' was that the pumping lemma is not really an equation. But you don't get hits if you talk abou

As smart as the Hacker News set may be, most people are not experts in the field and could do with a little context. Also, Aaronson's a well-known computer scientist, so this helps establish that the result's both credible and important in

Another mistake you might want to fix: >(like, matrix multplication isn't commutative, that means: A∗B≠B∗A when B and A are matrices) You want to say something like "A∗B isn't necessarily equal to B∗A when B and A are matrices." Neither

I think the point might be that if you don't pay attention to, and think hard about why your language may/may not fail certain of those checks, then you're doing it wrong.

Did you mean to write '100 lines/month' up there, or is that an exaggeration for comic effect? I have little experience with bad programmers--but you seem to know enough (or think you do) to throw percentages out there.

But isn't 'moving faster on the growth curve' exactly what it means to be a natural genius? Mozart didn't pick up the violin and instantly compose symphonies, but his talent helped him pick it up at an early age. And aren't you assuming tha
