Roland Deschain mashup sample app

"The doorway was the Lady's eyes. Roland Deschain was looking through them".

Roland Deschain is a sample app useful for demo purposes. Receives events from Instagram in real-time and shows in a map the location where every picture is being taken. Written in Java with Vert.x and deployed live on OpenShift, the PaaS (Platform as a Service) by Red Hat.

See it live:

Unstable, a few things to do:

  • Automatically subscribe to Instagram API geographies (based on locations.json)
  • Responsiveness
  • Upgrade to Google Maps API v3
  • Pause, rewind, forward, play
  • Multiple geographies with filters
  • Better cache architecture, maybe Redis
  • Etc
