Did someone declare it Neal Stephenson Day or something?
First, I see a link on /. to this New York Times article (user:generic, password:generic) about Riemann’s Hypothesis — kind of interesting, but you may want to skip it if you hate math 😉 Anyway, this hypothesis has to do with the distribution of prime numbers and the zeros of the Riemann zeta function. And I think there was something in Cryptonomicon about that zeta thinger .. I’d check, but my copy is at home.
And then, over on Penny Arcade they mention this e-gold stuff .. also connected to Cryptonomicon ..
