As the person whose comment triggered Nathan's question, I think I should answer.
Yes, there's far too much off-topic chatter

@flawr That's actually often a bad idea, you should only do that if you know the reason it didn't work was that you didn't use sudo and you know that you should :P
Write a piece of code that is executable in at least three different languages. The code must output the integer 1 in language number one, 2 in language number two, 3 in language number three etc.
Rules:
The output must be only the integer, but trailing newlines are OK.
The code can't take in...
@FryAmTheEggman I don't remember what else was said about Linux, but I do remember that for Macs, it is or used to be the case that all you needed to bypass the login screen or override the password was the installation CD.
@El'endiaStarman the unique role of mass is generating a gravity, and i dont see planetes falling downhill to the sun when crazily augmenting their mass !
Tropical geometry is a relatively new area in mathematics, which might loosely be described as a piece-wise linear or skeletonized version of algebraic geometry. Its leading ideas had appeared in different forms in the earlier works of George M. Bergman and of Robert Bieri and John Groves, but only since the late 1990s has an effort been made to consolidate the basic definitions of the theory. This has been motivated by the applications to enumerative algebraic geometry found by Grigory Mikhalkin.

We will use the min convention, that tropical addition is classical minimum...
@PhiNotPi Hmm, wait, if we're only interested in real values for X and Y, then there would no pairs that satisfy these criteria, right? If the sum is 3 and the minimum is 2, then the other must be 1, which is the true minimum, therefore contradiction.
You need it to meet a bunch of criteria for it still to be a simiring, I'm not super good at this, but I don't think that will work because that addition doesn't give complex numbers ever.
What about doing what Conor actually suggested, which is that you're not taking the minimum of the magnitudes, but whichever one has the minimum magnitude?
@flawr 4/20 is popular within the marijuana community for some reason, and the comic is basically that someone is getting excited about 4/20, but they don't use weed themselves, so they have no reason to do so.
420, 4:20, or 4/20 (pronounced four-twenty) is a code-term that refers to the annual consumption of cannabis and by extension, as a way to identify oneself with cannabis culture. Observances based on the number 420 include smoking cannabis around the time 4:20 p.m., as well as smoking and celebrating cannabis on the date April 20 (4/20 in U.S. form).
== Origins ==
A group of people in San Rafael, California, calling themselves the Waldos because "their chosen hang-out spot was a wall outside the school", used the term in connection with a fall 1971 plan to search for an abandoned cannabis crop...
Could someone tell me; was my edit here comprehensive enough for this to be reopened? (also, please let me know of any loopholes or things I forgot!) http://codegolf.stackexchange.com/questions/22/the-luhn-algorithm-for-verifying-credit-card-numbers-etc
