Information doesn't want to be scale free

"the scale-free network modeing paradigm is largely inconsistent with the engineered nature of the Internet..." For a decade it's been conventional wisdom that the Internet has a scale-free topology, in which the number of links emanating from a site obeys a power law. In other words, the Internet has a long tail; compared with a completely random network, its structure is dominated by a few very highly connected nodes, while the rest of the web consists of a gigantic list of sites attached to hardly anything. Among its other effects, this makes the web highly vulnerable to epidemics. The power law on the internet has inspired a vast array of research by computer scientists, mathematicians, and engineers. According to an article in this month's Notices of the American Math Society, it's all wrong. How could so many scientists make this kind of mistake? Statistician Cosma Shalizi explains how people see power laws when they aren't there: "Abusing linear regression makes the baby Gauss cry."

Cosima Rohilla Shalizi - Polymath & Ultimate Pantologist

Ibn Hazm
The Dove's Necklace


Cosma Rohilla Shalizi, who contains universes: Notebooks, Pieces for the SFI Bulletin, The Bactra Review, Books and Other Texts I've Put on the Web, Poetry and not the worst links page I've ever seen. This is the worst home page ever, according to yankthechain. I'm very proud. He likes, among many others, Avram Davidson, Sappho, Jack Vance, Edna St. Vincent Millay and Georg Christoph Lichtenberg. Courage, garrulousness and the mob are on our side. What more do we want? Now, is that a tagline or what?
