6. Array permutation in Python

   In Python, if you ignore the battery that's included (random.shuffle) you have this:

   import random
   l = range(0, 20) # array to permute

11. Looking for a Django Reader

    I've just finished the last rough draft of a short e-book, An Intro to Testing Web apps with twill and Selenium. The book has four sections:

    1. Introduction
    2. twill intro
