Allows you to easily run octave version 3. For instance, this is useful if you're on Andrew Ng's machine learning course. Newer versions of Ubuntu only include octave 4 and it's a hassle to compile it yourself.
Run it like this:
sudo docker run -i -t --rm \
-e DISPLAY=$DISPLAY -u joe -v /tmp/.X11-unix:/tmp/.X11-unix:ro \
-v $HOME/ml:/home/joe \
Open another console and enter "xhost +". After using octave use "xhost -" to restore strict access policy.
