Random walk

Random walk – Wikipedia, the free encyclopedia

I remember some article about periods of extreme regularity in random walks… but don’t remember whether periods of regularity are inherent in certain types of truly random walks, or whether it was because the algorithm wasn’t really random… 

Surely extreme order and even self-organization can arise from entropic systems – like ripples in the sand on a beach, or stars forming from interstellar dust… hmm…

Amazon AWS supercomputing

Is anyone selling distributed parallel processing to universities and laboratories based on Amazon’s cloud computing initiative? Even if the base price per teraflop isn’t great, you can scale linearly and you don’t need any physical space at all… it seems like there would be a lot of benefits.

There is some discussion on the idea here, but I haven’t seen any serious implementations.
