6. Unintended consequences of the decorator notation

   Spoke yesterday with Bill Punch, a CS professor at MSU who is using Python for intro CS. He told me his tale of tracking down what an '@' sign meant (it's a decorator, http://docs.python.org/ref/function.html). Needless to say it took him quite a while to google …

7. What book?

   The O'Reilly bookstore didn't actually let you buy our Introduction to Testing Web Applications with twill and Selenium for the first 24 hours -- some bug on the Web site, apparently...

9. Seen on the agile-testing list

    Just saw this, in-place permutation (of a Java array, in this case).

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

    import random
    l = range(0, 20) # array to permute
    
    for j in range(1, len(l)):
       k = random.randint(0, j)
       l[j], l …

11. Patching subprocess revisited

    So, I've finally put together a patch for subprocess; see replacing-commands-with-subprocess for background, and this python-dev thread for discussion.

    You can go grab my patch (or the entire subprocess module) here. I'm interested in comments, either here or via e-mail.

    Note that I am putting together a separate docs patch …

12. A (Short) Meditation on Debugging

    I spent part of Saturday and Sunday working on Cartwheel, and then I spent part of Monday morning nailing down a bug that I thought I'd introduced. The process of tracking down and fixing this bug led me to give serious thanks for version control and automated tests, and at …
