OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	require 'yaml'
	require 'logger'
	require 'active_record'

	namespace :db do
	def create_database config
	options = {:charset => 'utf8', :collation => 'utf8_unicode_ci'}

	create_db = lambda do \|config\|
	ActiveRecord::Base.establish_connection config.merge('database' => nil)

	function declOfNum(number, titles) {
	cases = [2, 0, 1, 1, 1, 2];
	return titles[ (number%100>4 && number%100<20)? 2 : cases[(number%10<5)?number%10:5] ];
	}

	use:
	declOfNum(count, ['найдена', 'найдено', 'найдены']);

	# lib/custom_logger.rb
	class CustomLogger < Logger
	def format_message(severity, timestamp, progname, msg)
	"#{timestamp.to_formatted_s(:db)} #{severity} #{msg}\n"
	end
	end

	logfile = File.open("#{Rails.root}/log/custom.log", 'a') # create log file
	logfile.sync = true # automatically flushes data to file
	CUSTOM_LOGGER = CustomLogger.new(logfile) # constant accessible anywhere

	#
	# Optimized version which uses to_yaml for content creation and checks
	# that models are ActiveRecord::Base models before trying to fetch
	# them from database.
	namespace :db do
	namespace :fixtures do
	desc 'Dumps all models into fixtures.'
	task :dump => :environment do
	models = Dir.glob(RAILS_ROOT + '/app/models/**.rb').map do \|s\|

	puts route

	# Family tree node, mother and father are Person values as well
	Person = Struct.new(:name, :mother, :father)

	# Recursive dsl in a mutating builder using Docile
	def person(&block)
	Docile.dsl_eval(PersonBuilder.new, &block).build
	end

	# Linux
