I wonder how to go about to collaborate to the OSM ecosystem with code. Does anyone know what are the cool projects within OSM in C/C++? (i.e. not web stuff)
It could also be a niche thing, like if you make an app that shows the nearest defibrillator or other emergency facilities that people might need in a pinch. Any area gaining good coverage of this type of data would immediately have an app to turn to. With adoption also comes the influx of new contributors.
