The articles about this keep saying that "recent international research has shown there may be a link" without providing the source of that data! I can't find it anywhere, all the studies I can find show no evidence of a link. What the hell are these assholes talking about?! Why don't these journalists think this is an important piece of information to include with their articles?

I don't care if a bunch of nuts half a world away banned wifi for their elementary students. I but do care if they had a good reason to do it!

That's outdated, since we don't enforce that policy. As long as the feature is opt in, it is acceptable to introduce it in an update.

How do you figure? Each ticket has the same chance of winning, the more you buy the more likely you are to win. But the odds are such that the expected return over the long run is less than what you would pay in.

As a poker player, I never release my trump card early in the game.

The problem is this: the elliptic curve digital signature algorithm, which Bitcoin transactions rely on for security, has three inputs: the transaction, the signerâ(TM)s private key and a random number. The algorithm then outputs two values, denoted r and s, where s is calculated with the formula k-1(z+rd), z being the hash of the message, k the random number and d the private key. r is dependent only on k. Thus, if the owner of an address signs two transactions with the same random number (and of course the same private key, as every address is linked to one private key), one can extract two s values from the two signatures, subtract them to make the rd terms cancel out, and extracting the private key from there becomes a simple division problem (a more detailed writeup can be found here). Normally, this is not a problem; given a true random number generator, the first âoecollisionâ should take place roughly at the same time as the heat death of the universe. As it turned out, however, java.security.SecureRandom proved to be not so random, generating the same âoerandomâ number twice on many occasions.
