Subject: Question: Downloading files with open(-uri)?

Hi,

   I could need a quick hand here.

   I want to watch the RailsConf 2006 videos and want to download  
them with a script.

   Unfortunately open("http:/xx") never comes back? Any idea what I  
am doing wrong here?

   I tested it with an URL that returns plain html and that worked  
fine. See the first line, ibm.com.

require 'open-uri'

urls = %w{
http://ibm.com
http://downloads.scribemedia.net/rails2006/03_martin_fowler_full.m4v
http://downloads.scribemedia.net/rails2006/02_dave_thomas_full.m4v
http://downloads.scribemedia.net/rails2006/01_dh_hansson.m4v
http://downloads.scribemedia.net/rails2006/04_paul_graham_full.m4v
http://downloads.scribemedia.net/rails2006/06_railsCorePanel_full.m4v
http://downloads.scribemedia.net/rails2006/07_why_lucky_stiff.m4v
}
BUFFER_SIZE = 1_024*1_024*1

urls.each do |url|
   puts "downloading #{url}"
   open(url) do |input|
     puts "opened connection."
     output = open(url.split(/\//).last, "wb")
     while (buffer = input.read(BUFFER_SIZE))
       print "."
       $stdout.flush
       output.write(buffer)
     end
     output.close
   end
   puts "done."
end
puts "All downloads done."

Cheers,
Mariano
