As long as you know some coding, you can do all kinds of cool things in this day and age. Take Patrick Jackson, a firefighter who’s writing code to help rescue teams save time and lives. He has built an app that routes incoming emergency calls to Glass, a find hydrant app, and others. He is now working on apps that provide building floor plans to firefighters and schematics of vehicles to help rescue teams save time. This is one special guy. More importantly, this issues how much potential Google Glass has.
