Another prime number down, infinity to go

    New rule: it should be against the law, and you spend time thinking about it in the Hague, to calculate any large prime without knowing all the primes that come before it.  You cannot skip ahead.

    I love the EFF. But what reason could they possibly have for offering money for a new prime number?   Shouldn’t they be using that dough to fight the good copyfight?

      Prime numbers are used in cryptography, so the EFF would use that to help with internet privacy.

        Mersenne primes aren’t particularly useful for cryptography.  There aren’t very many of them, and they’ve got special forms which make them easy to find but might interfere with cryptographic use.  On the other hand, they’re a good problem to use for developing tools for large distributed computations, and potentially more practical than looking for Space Aliens.

      It’s a matter of collateral benefit, I think. Calculating a 100 million digit prime would require a breakthrough in computing power, algorithm design or mathematical theory, all of which would most probably find some good wider use. See also: indirect benefits of space race.

      “Prize money comes from a special donation provided by an individual EFF supporter, earmarked specifically for this project. Prize money does NOT come from EFF membership dues, corporate or foundation grants, or other general EFF funds.”

    Whenever someone tells me to “pick a number, any number”, I just start rattling off digit until they get bored/aggravated and usually ask me to stop.

    i got it right here, but i cant put it here due to space and time constraints. nor can i tell you ’cause of space and time constraints. sigh
