I recently gave a talk about my experiences with the C++ Catch Unit Test Framework at our local C++ user group. The slides and video from the talk (in German) are now available on my website.

Matias Dahl has looked at historic OSM data and done some analysis on changing use of the amenity tag including some pretty cool graphs. Nice work and potentially very useful. And he used node-osmium for it. Now, how do we get something like this into a continuously updated service, maybe even into taginfo?
