  • 1. The Twitter Instant Speed Meter
  • 2. Why ?
    • There is NO instant global metrics about Twitter
      • (until few days ago)
  • 3. Why ?
    • I would like to code a simple Java Twitter related app to deploy on Java Google App Engine
  • 4. Why ?
    • And try to play with social viral effect and analytics
  • 5. Principle
    • API used: Public Timeline
      • Doc: http://apiwiki.twitter.com/Twitter-REST-API-Method:-statuses-public_timeline
      • 6. URL: http://api.twitter.com/1/statuses/public_timeline.xml

  • 8. Principle
    • Public Timeline is read each minute (using a cron)
    • 9. First tweet ID and Timestamp from the list are stored
    • 10. Speed is extrapolated by « a rule of 3 » based on 5 observations
    • Each hour (another cron), hourly speed is calculated
    • And all these data are stored and used to display funny gauge or graphes
  • 11. Some (more or less) funny observations
  • 12. A long term trend ... yes Twitter is growing
    • I know, this graph is awful, but interesting ;-)
  • 13. (Attempt to a) Viral effect
    • TweeSpeed allows you the Tweet the Speed
  • 14. (Attempt to a) Viral effect
    • TweeSpeed website URL is also in the message
  • 15. The Future ?
    • Complete refactoring to
      • Calculate better trends (weekly, monthly, ...)
      • 16. Display more beautifull graphs (it'll not be so difficult)
      • 17. Create an API
    • Finish the Mobile Version (Android) which is another 1 hour developped totally useless experiment
    • Got a post in Mashable or TechCrunch (or both) ;-)
  • 18. Thanks for your attention
