Agile lie detector


A lie detector for your mobile phone.

Agile Lie Detector measures the amount of stress caused by lying in a person’s voice and displays this information in a graph in real-time.

Modules mixed into an instance

class Object
  def extended_by
    class << self; ancestors end
  end
end

foo = Object.new
foo.extend Enumerable
Object.ancestors.include? Enumerable
# => false
foo.extended_by.include? Enumerable
# => true
