If you've been in the talk, your know what this does: it's a very simple example of a WebSocket server-client interaction.
The server is a Python script. Just run it after installing some dependencies:
- Twisted==12.2.0
- autobahn==0.5.9
- psutil==0.6.1
The client is a webpage containing some JavaScript. You'll have to add d3.js to the same directory and serve it from a webserver.
With the server running, load the webpage. The WebSocket connection will be established and the server will push CPU usages to the webclient every second.
Happy hacking!
