FileUtils.mkdir_p(WWDC_DIR) unless File.exists?(WWDC_DIR)

uri = URI(PATH)

sessions.select {|x| x.year == 2015 }.each do |x|
  sessionURL = x.download_sd
  file = sessionURL.split('/').last

  next if Dir.entries(WWDC_DIR).include?(file)

A handy script, thanks for this one. Would be nice to know the total download size beforehand though. Just to be sure there's enough space to get them all.
