This is my best try at transcribing of the lightning talk I gave at RUG::B on April 2016. Due to poor time management (LOL) the delivery was rushed and some examples were skipped, I hope having them posted here makes them more useful.

xargs

xargs is a small but very useful program that is installed in most if not all of your computers¹. Many of you probably know it. Those who don't will learn something really useful, but those who do will learn a couple of cool tricks, too.

Why xargs

You might have heard about the Unix philosophy:

	# This set of classes implement the algorithm described in
	# > Jia, T., & Barabási, A. L. (2013).
	# > Control capacity and a random sampling method in exploring controllability of complex networks.
	# > Scientific reports, 3.
	#
	# This algorithm obtains a score for each node of a network telling how 'driver' it is
	# i.e. What is the chance this node is in a set of nodes that can control the whole network
	#
	# Look at the test files to see how to run this algorithm
	#

	# Add these methods to your ApplicationController. Then, any controller
	# that inherits from it will have these methods and can programmatically
	# determine what filters it has set.
	class ApplicationController < ActionController::Base

	def self.filters(kind = :around)
	_process_action_callbacks.select{\|f\| f.kind == kind}.map(&:filter)
	end

	def self.before_filters

	#!/usr/bin/env ruby

	# Put this file in the root of your Rails project,
	# then run it to output the SQL needed to change all
	# your tables and columns to the same character set
	# and collation.
	#
	# > ruby character_set_and_collation.rb
