One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

/ A simplistic way of loading and rendering HAML partials (header.haml, footer.haml, nav.haml... you name it) without Rails
/ Useful when using tools like LiveReload http://livereload.com/
/ but don't want to configure a web server just to use PHP include/require constructs (discussion http://help.livereload.com/discussions/questions/22-haml-partials)
/ It could be improved/simplified using a helper http://stackoverflow.com/questions/5436769/partial-haml-templating-in-ruby-without-rails/5436973#5436973
/ Check out the Jade version https://gist.github.com/2593727

%html
  %body
    %header    
    = Haml::Engine.new(File.read('/path/to/your/partial.haml')).render

# When an RSpec test like this fails,
# 
#   @my_array.should == [@some_model, @some_model2]
# 
# RSpec will call inspect on each of the objects to "help" you figure out
# what went wrong. Well, inspect will usually dump a TON OF SHIT and make trying
# to figure out why `@my_array` is not made up of `@some_model` and `@some_model2`.
#
# This little module and technique helps get around that. It will redefine `inspect`
# if you include it in your model object.

how to into git (and GitHub)

This is a handy reference for setting up and using git to contribute to projects on GitHub. It is by no means a complete guide to using git; use http://gitref.org for that.

Update: This site provides some excellent visualizations of what various git commands do. Highly recommended.

Killing supervisor if any of it's child processes fail

The trick is to only register the listener for events that indicate failure, namely

• PROCESS_STATE_STOPPED
• PROCESS_STATE_EXITED
• PROCESS_STATE_FATAL

Once they do, we should send a SIGQUIT to Supervisor.
