As I have to do some ruby presentations in the upcoming weeks at university, I decided to play a little bit with Sinatra. Sinatra is a minimalistic web-framework, perfectly suited for 1-file web-apps dealing with requests in a REST-like way.
As I always wanted to have a simple "upload and forget"; storage for my GPX files (XML GPS-traces), I decided that I'd give it a shot.
I already had codec the whole GPX parsing and analyzing a while back and only had to refactor it and put it into a working web-app.
UPDATE: changed name to "run-a-log"; and added some stuff
