To run this presentation, you need to have Vert.x installed on your computer, and a running mongo server. Then simply run:
$ vertx run --clustered preso.js
Then browse to http://localhost:8080 to view the presentation slides or head over to the demo to see some Vert.x in action.
If you want to hack the demo election, run the cluster node as its own verticle.
$ vertx run --clustered cluster_node.js
