>It is licensed under the following terms: you must pay me $0.0001 per hour per CPU core you run it on.

Reminds me of the Wheat and Chessboard Problem.

Only difference is that the guy will have to wait some millennia to get any significant amount of money.

Because we know that the guy who asked the question will not be using a supercomputer.

Judging by the up-votes over there on SO, I think I've identified at least 200 people with entirely different senses of humor than my own.

I wonder if that guy is a troll or honestly ignorant. I had to laugh a the comment of the guy who said:

It will run for 10790283070806014188970 years. Which is about 83 billion times longer than the age of the universe.

Along these lines, see the code in the accepted answer:

    Console.WriteLine("Umm... why hasn't the univese ended yet?");

Not really.

More like a political story with no relevance to hacker news gets downvoted.

(And is clearly mentioned as off-topic in the guidelines: "Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.")

Yet "Slow news day" and "Speed it up" are so very on point.

I once worked with a guy who liked to say the "G" stood for "guaranteed". I kind of like that better. No more worrying about whether "global" is good enough, or if you need to go to the UUID that one commenter mentions.
