I know the general format for package names in Debian and Ubuntu. Some packages have additions to the standard numbering scheme with obvious meaning like svn20090426 etc. But also quite a few packages have dsfg in their name (e.g. 2:1.0~rc4~try1.dsfg1-1ubuntu1) – what does that mean?
Is it just a typo of the Debian Free Software Guidelines (DFSG)?
What features does Ubuntu One provide that others services do not have? Can I use Ubuntu One only on Ubuntu machines? What about sharing data/folders with others who do not have Ubuntu One?
I have GPS tracks (in gpx format) that I usually use to geotag photos. Is there a simple software to view these tracks (i.e.: not use Google Earth)? A bonus would be simple modification, like deleting waypoints. TangoGPS seems to offer GPS track import only in connection with geotagging for pictures.
