The word "proportional" in "f(x) is proportional to x" does not mean that f(x) is monotonically increasing with respect to x; it means that f(x) = kx for some constant k.
(Likewise, the word "inversely proportional" does not mean f(x) is monotonically decreasing with respect to x; it means that f(x) = k/x for some constant k.)
Yeah, and what's with the vi people and their counter intuitive hjkl navigation? Jesus, did they pull right out of their ass? htns would make sense, but the keys hjkl are all over the place, and only one is one the home row.
Standards would be so much more fun if they revolved around me.
In my Linear Algebra course, often for fun, rather than solving problems I used to write programs to solve problems, and then have the programs solve them. I found it much more enjoyable to write a matrix multiplication routine than to just carry out the algorithm myself, using pen and paper.
Why would you be multiplying matrices in Linear Algebra? You took the wrong Linear Algebra course.
I'm a math guy, and I'd say that you actually are a math guy and that you just don't know it yet. You seem to have a strange impression about mathematics.
I reassure myself that this is okay because I really am much more creative than mathematical (not that those two are opposites, just that often they tend to be mutually exclusive).
Definitely not true! You can't be good at mathematics without being creative. Could have an uncreative person have invented Cantor's diagonal proof that there are more real numbers than integers? Creativity is tremendously important in mathematics because in order to solve or prove something, you often need to approach the problem from a bunch of crazy angles until one works. And if you're not creative enough to think of these crazy angles, you're not going to solve the problem.
For example, I can remember people cursing about a simple calculus problem: differentiate 4sin(x)cos(x)/tan(2x). The uncreative person uses the product rule and the quotient rule to grind out the answer. The creative person stops and looks around for any trigonometric identities he can pull out of his ass. And there is one! 2sin(x)cos(x) = sin(2x), so we have d/dx[4sin(x)cos(x)/tan(2x)] = d/dx[2sin(2x)/tan(2x)] = d/dx[2cos(2x)] = -4sin(2x).
A lot of the early math courses, like Calc I, II, multivariable calc, and differential equations, tend to teach algorithms for solving the problem. Students learn how to grind through derivatives and integrals and differential equations that fall into certain categories. This is not interesting and noncreative students can get by. But later on, you get many more open ended problems. All of my math assignments follow the pattern of "prove this." (I'm a math major.) In my linear algebra course, the idea of vectors as lists of numbers or line segments with arrows on them is something that the professor jokes about. The only numbers I have seen are 1 and 0, and they don't even refer to real numbers.
You are so definitely a math person, enjoying things like Theory of Computation, it is funny to hear you say otherwise:-)
Why is "competetive programming" so great? I'm not trying to troll, but is this for some lack of being able to compete in sports or something? Why does this too have to be competitive? It seems like everything in here has to be tested and ranked.
My university had a team, I went to one meeting and realised how stupid and hokey it was. Half of it was an intellectual circle-jerk and the other half was some practicing. All too l4m3.
Why is "football" so great? I'm not trying to troll, but is this for some lack of being able to compete in academic competitions or something? Why does this too have to be competitive? It seems like everything in here has to be tested and ranked.

Of course they would. But people don't think rationally after disasters, so why would we listen to what they have to say? In fairness, maybe we will get some sense and realize that our number one enemy is still the laws of physics, not terrorists.
It is much easier to find out the appropriate shape of a key from a lock than it is to break into a car, find the computer, take out the computer, look in its memory, and see the key.
And even this would not even be enough. The onboard computer could store a product of two very large prime numbers, and the USB key could store one of the prime numbers. Then the key stored on the onboard computer could be printed on the outside of the car if you wanted, and it would still be secure.
So the computer itself isn't the point of failure when it comes to keeping your car secure.
Of course, whenever dealing with vague notation or semi-vague notation such as this, it will be explicitly clarified how the notation should be interpreted. You'll sometimes see it explicitly pointed out that z^z^z^z^z means z^(z^(z^(z^z))). But nobody ever explicitly mentions that z^z^z^z^z is used to mean ((((z^z)^z)^z)^z), because, well, they'd just write z^(z^4).
No sane mathematician actually writes chained exponents when meaning the first way,((a^b)^c), because when actually writing superscripts, you either end up with a doubly-superscripted number or it looks like (a^(bc)). And ((a^b)^c) is actually equal to (a^(bc)), which is the convenient way of writing it. (To convince yourself of this, when have you ever seen written (e^(-1/2)^x^x) with progressive superscripts? Or (((e^(-1/2))^x)^x)? That famous expression is always written as (e^(-1/2*x^2)).
Thus, whenever a^b^c^...^n is seen in the wild, it gets interpreted as (a^(b^(c^(...^n)))). For it would only be used when that is the desired meaning.
I thought that Russia was part of Europe! For a while, the Soviet part of Europe, but still part of Europe! Well, at least part of Russia is part of Europe. So is Russia joining itself? Partly? If you're in the European part of Russia, do you join Russia? Are Asian Russians getting joined by European Russians? Oh wait. I've got it.

Why is it so important to you that your submission is the one that gets accepted?
Considering speed-of-light limitations and all, you'd have to be standing at the telescope for a pretty long time.
Blame the moderators! They're the ones who took what I said seriously!

No problem. It means

Real programmers use Perl to write FORTRAN.
Yes. Unencrypted text printed on pages of a book, sold in a bookstore near you, is uncrackable. No, ROT-26 doesn't count.
"macs" spelt backwards is "scam" .
So.. you're saying that macs are the complete opposite of scam?
It's impossible to prove a negative.
Oh? I'd like to see you prove this claim.
Maybe the sun went around the Earth more frequently in Asia.
They are rights online? Yes, the Chinese people embody the rights of others online.
(For the record, I do understand that you are simultaneously joking about the shmeditors' inabilities to spell.)
I don't like that code either; I'd write
(define (gnc:leap-year? year)
(cond ((= (remainder year 400) 0) #t)
((= (remainder year 100) 0) #f)
(else (= (remainder year 4) 0))))
As the other poster pointed out, Python can be written moronically too.
That's a lot of millibytes!
