I’m a little late on this one but I just found out about this, the official Google Developer Group is holding a devfest event at GUST University for 3 days. The first day will include technical talks about Android, Google App Engine, Google Cloud Endpoints and HTML5/Chrome. Second day will have developers teaming up and pitching ideas. Third day will be an all-out hackathon.
If you’re interested you need to hurry up and register [here] because sign ups close in 5 hours.
