title: How to use node.js in a real time gps tracking application?
body: <p>I am trying to understand how node.js will fit in my scenario.</p>
  <p>Currently, a mobile device sends gps coordinates to a Rails backend thru POST. The mobile device sends it every minute.</p>
  <pre><code>POST http://127.0.0.1:3000/location/
  </code></pre>
  <p>My RubyOnRails web app can display the history of locations on a map, no problem with this.</p>
  <p>But my experience in nodejs is still in its infancy and I would like to understand how to display a map for real time GPS updates as they come in.</p>
