Python's Super

First thing that comes to mind : why do I need to name the superclass explicitly, instead of passing in self.__class__ (or better still, type(self)) ? Because:

class Base(object):
    def method(self):
        print 'original'

class Derived(Base):
    def method(self):
        print 'derived'
        super(type(self), self).method()

class Subclass(Derived):
    def method(self):
        print 'subclass of derived'
        super(Subclass, self).method()

leads to:

>>> Subclass().method()
subclass of derived
  File "<stdin>", line 4, in method
  File "<stdin>", line 4, in method
  File "<stdin>", line 4, in method
RuntimeError: maximum recursion depth exceeded while calling a Python object

And this pretty much explains the second question I had.

Set Up Octopress in Windows 7

Download ruby from here - I downloaded rubyinstaller-1.9.3-p448.exe

Install it, add it to path then create a folder to host octopress and your blog (in DB naturlich) and fire up git bash.
