This document outlines an agenda for a 48-hour hackathon in Paris to invent the city of the future. It will include presentations from Cisco and various technology partners on topics like smart cities, Internet of Things, and cloud platforms. Participants will then pitch project ideas before forming teams and beginning development. Over the weekend, teams will work on their projects, receive mentoring, and do practice pitches. On the final day, projects will be presented to a jury for cash prizes. The goal is to generate innovative ideas for connecting people, data, and devices to improve city services.
