/ 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

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
