title: How do I send a message to a udp socket in Ruby 1.8.7
body: <p>I am able to send a message to a udp socket in Ruby 1.9x. I need to make this backwards compatible to Ruby 1.8.7, but I am not able to find any documentation on how to do this. Here's what I have for 1.9.x:</p>
  
  <pre><code>require 'socket'
  socket = Socket.new(:INET, :DGRAM)
  addr = Socket.sockaddr_in(UDP_PORT, UDP_HOST)
  socket.connect_nonblock addr
  socket.send(some_json_string, 0)
  socket.close
  </code></pre>
