Real data, real time
This demo uses data from the Sixapart Livejournal updates feed, a streaming XML service that pushes the full text of all posts made to Livejournal, as they're made. Our daemon listens to that stream, indexes all the words in the incoming posts, and counts the word frequency. The number of 'mentions per minute' is tracked over a five minute rolling window, and word counts injected into Meteor server when the values change. This page has a Meteor Javascript client that subscribes to the 'sngst' channel and fires JS event handlers when new messages are received.
The entire process, from the author pressing the publish button to the word frequency figure changing in the table above, is event driven. No polling going on anywhere.
