The article specifically says the PageRank eigenvector is only recalculated once a month, approximately. Even though Google uses some clever numerics to calculate the eigenvectors to a 25 billion by 25 billion matrix by iteration, it still takes several hours to finish.

That seems to be a troll, but just for the note: I said I think I invented something. If I was cock-sure of superb originality and power, I'd be off trying to publish in academic journal, not discounting a nifty visualization trick over in a/. comment.
I actually didn't even use the mod function in my code. I produced the images in PPM format, and color 257 = color 1 in that format. It was an accidental "invention". (I wonder if it's been done properly before me).
You could plot graphics that represent levels as colours. I think I invented a kind of R^2->R function plot that represents a Z value as the degree of grey (0 being black, 255 being white) corresponding to Z mod 255. The result is that the more frequent "cuts" (sudden changes from white to black) are, the highest is the derivative.
Precisely. That's what Sorcerer, the Linux distribution, does.
In any case..

.. you have to admit that Adsense is a firmer business model than Pets.com -- or heck, graphical nonrelated banner ads -- and RSS, open web services APIs and stuff like del.icio.us or Flickr are more valuable content than the websites of 1997.
Maybe some lessons _have_ been learned. That doesn't mean necessarily that current pricing isn't off, or that the dynamics of self-fulfilled prophecies have changed, but there's definitely more value on the internet now than around 1997-1999, with less flowers.com fluff.
Maybe a part of the 1990s tech bubble wasn't unwarranted overvaluation, and that adds to the hypothesis of a firmer expansion now.
It's naïve to just go "ah, history repeating itself". History never repeats itself, except as a farce.
Um, forgot to post my age. (I'm the *Snif* anonymous coward) I'm 23. I was 22 when I first had sex.
Don't despair. If you're not good with teh chicks, wait for true love. It's pretty awkward still being a virgin at 22; women expect sexual experience you haven't, and you need someone who will tolerate you not knowing what the hell to do the first times.
I guess, anyway. Sex in a deep romantic relationship is more fun, anyway. It can be wild & rough, it can be caring & sweet, it can involve teh weird fetishes you wouldn't confess to the average chick, and all.
Just try to be an interesting person and don't worry too much. Geeks are interesting people in their own right, and as long as you can geek out over a wider range of subjects you should be all set. In your early-20s, the social skills you lacked during your teens aren't that complicated anymore, and it's easier to go out and mingle.
Oh, btw. I met my g/f on IRC. She was first attracted to my grammar.

Where Haskell does shine is in its generalized algebraic abstract type support. Maths (well, numbers) are one type that's predefined and intuitive to use, and it generates lots of examples of the pretty kind, but import a parser library like Parsec and you have non-"math" examples that take the "formulaic" declarative style to great levels of elegance. Or you can import a Tree library and have it search domains with great beauty and smartness.
Say we want to verify the Collatz conjecture for a given space of seed numbers. Bruteforcing won't work: if we can't prove that the Collatz sequence converges for a given n, how do we know when to interrupt Collatz(n) and move over to Collatz(n+1)? Behold search over a memoized rose tree in a two-minute hack:
invFunc x = (x, [if (x-1) `mod` 3 == 0 then (x-1) `div` 3 else x, 2*x]) invTree = unfoldTree invFunc upto_ a = concat . take a . levels . invTree upto a = upto_ a 1 findCollatz x a = elem x (upto a) minLevelCollatz x = until (findCollatz x) (+1) minLevelCollatzes = map minLevelCollatz [1..]
OTOH, it's generally a bad idea to do numerics in Haskell. At least for the next few years. Even fanatic Haskellers will point you to O'Caml for numerics stuff.

Start him on Dr. Scheme http://www.drscheme.com/ as a calculator, and gradually teach him to write functions, evaluate lists. The mere incentive of having the computer doing his homework as soon as he builds the abstract toolkitshe needs will have him writing simple functional programming libraries in weeks.

Yeah, it should have been mod 256.
