Firstly, if you're wondering what happened to all the ObsTCP stuff, it didn't disappear, it just moved to a different blog. Things are still moving as fast as I can push them.
This book has some good, if unoriginal, points about the stupidity of much of the modeling done in today's world, esp the world of finance. Sadly, these are hidden in many pages of self-centered rambling and discourse on adventitious topics. If you're thinking of buying this book, get The (Mis)behaviour of Markets by Mandelbrot instead; you'll thank me.
