note jettero <blockquote> every random number generated was unique. This was expected. </blockquote> <p> I had a stats teacher that would have everyone write down a coin flip sequence and then he'd explain how he could tell who cheated: not enough repeats. I guess I'd expect to see a few repeats in my sequence of random numbers. Probably not as many as you're seeing... I think there are other [href://http://portal.acm.org/citation.cfm?id=1315304|problems] with the windows PRNG too. Maybe win7 fixed it. <p> I guess I expected to find some things on CPAN for this, but I didn't -- unless you're willing to use cygwin. Then there seem to be a few choices. [mod://Crypt::Random] (will this work without the entropy daemon?) and [mod://Math::Random::MT::Auto] (should I be using this too?) seem fairly interesting. <p> UPDATE: Ahh, interesting. I didn't understand the issue at all. <div class="pmsig"><div class="pmsig-16186"> <p>-Paul</p> </div></div> 803632 803632
