Title: Hash/date collision?
Post by: Echo51 on August 27, 2010, 03:34:12 PM
Is there the possibility for a collision in the generator, as in 2 identical maps but on 2 different dates?

This is theoretically possible for any given sequence of maps, but super, mega, absurdly improbably in a sample size of 3.6 million maps.

Seems improbable in that small sample size, yeah, but we'll see eventually :)

My bet is with the island maps.

Well, a simple calculation (amount of blocks on a map) to the (amount of possible elevations) gives 428billiard, or 428 quadrillion for you Britains and Americans, and that's just the terrain, so no emitters, totems, OC placements or spores. So only to have the same terrain there's only a chance of 1 to 118 milliard (that's 118 billion for you Britains and Americains), so it isn't very likely.

If you want to lump British and American numerical systems together, you should know that a billion is not the same in the UK as it is in the US. Common usage has obfuscated the issue and made the US numbering system more common, but the original British system (still used by purists) has billion larger by a factor of 10^6 than the American system.

And here is an authoritative source to back up my statement: The Oxford Dictionary (http://www.oxforddictionaries.com/page/114).

Ahem: "British English has now adopted the American figure, though, so that a billion equals a thousand million in both varieties of English."

You're authoritative source only seems to contradict your statement  ;D, but I keep learning things here.

In my post, that you quoted, I acknowledged that the US system is more common, but that purists would then not make the differentiation that you made.

I don't get it anymore, so you say that purists wouldn't make the differentiation I made, but I never made a differentiation between US and UK, I just said it for the British and Americans on one side, and the rest of the world on the other side ???

Just as weird as reviving a thread that's a month old when you've got nothing new to add?

well i'm doing it from a mobile phone so it doesn't look the same there isn't a date.
