What is AOP?

Aspect Oriented Programming is a means to change the behaviour of – or add behaviour to – methods and functions (including constructors) non-invasively. The added behaviour is called “advice” and can be added before, after, or around the function it advises.

This description is similar to the Extract Surrounding refactoring method. The difference is in the direction of the change. It seems AOP is more focused at modifying existing behaviour non-invasively; where as the Extract Surrounding Method actually changes the source code to allow this type of behavioural modification.

Take a webcam shot and save it in the pictures directory. Depends on tenderlove's av_capture: `gem install av_capture`
#!/usr/bin/env ruby
require 'av_capture'
require 'pathname'
session = AVCapture::Session.new
dev = AVCapture.devices.find(&:video?)
dir = Pathname(File.expand_path("~/Pictures/av"))
Dir.mkdir(dir) unless dir.exist?

Select a random n values from an array that might have < n values
words = %w{foo bar baz}
n = 10
# If we use sample, we get a random order but never
# more than 3 entries:
words.sample(n)
# => ["bar", "foo", "baz"]
# A solution:
n.times.map { words.sample }
