Interesting links (2011-12-31)

Last batch of interesting links collected in 2011 ... starting with Pricing and Trading Networks: Down is Up, Left is Right: A fantastic post from Chris Marget explaining the behavior of trading floor networks. For me, it was an amazing view into a parallel universe with a completely different set of physical laws.

And here are the other articles I found interesting in semi-random order:
