It's hard to create an app. It's even harder to get the app published and make it available for other people. That's true whether you’re a developer or a technical writer. You need to put yourself on the edge and take the jump. You need courage, conviction, and knowledge. Above all, you need documentation and examples, they give you the edge. This presentation tells the story of a tech writer, a map, and an app. Tech Comm on a Map is an interactive web-based map that shows events of interest to technical communicators. You’ll hear why Sarah decided to create an app and how she went about it. You’ll see some code and understand the nuts and bolts ofthe app: where the data is stored, how it gets there, how it ends up on a map for everyone to see.
