Granola: Workout log for GPS enabled cyclists, runners, and hikers.
Rounder: Poker for your GNOME desktop.
Tito: A tool for managing RPM based git projects.
I've been doing some work recently on cobbler4j, a small Java library for interacting with Cobbler over XMLRPC based on the work done to integrate Cobbler into Spacewalk.
Right now the library basically allows you to open up a connection, and interact with the core object types (repos, distros, profiles, systems) as if they were actual Java objects. In the future this will likely grow to include other operations and background tasks. And as a required disclaimer, this is still very much a work in progress and should not be considered stable.
The cobbler4j wiki page covers most of the high level details on what it does and how to use it.
Here's a sample program:
import org.fedorahosted.cobbler.CobblerConnection; import org.fedorahosted.cobbler.Finder;
It's doing most everything I want now, just need to clean up some rough edges (quite a few actually) and roll it up for a release.
As previously alluded to I decided to go ahead and start working on Granola, a quick and dirty app for importing and displaying data from a GPS. Still pretty rough around the edges but this is what I've got so far:

Would love to hear some feedback on what other GPS enabled cyclists/runners/hikers out there would like of such an application, even UI feedback if so inclined. (though please ignore the terrible spacing in the lower half of the screen, I know that part sucks :)) My bare bones list of functionality I want out of a 0.1 release is up on the project page. A right click content menu option for Google Maps is still pending, as is an activity type filter dropdown above the main list of activities.
