  • D-Bus and Python: asynchronous method implementation

    This is a quick demonstration of how to implement a D-Bus method in Python using asynchronous callbacks. I recently added support in system-config-printer for determining the best driver to use for a particular printer.  This is an expensive operation, largely because of the time it takes to get a list of available drivers from CUPS,…

Fedora 15 has been released for a little while now, including GNOME 3.  One of the great new features in this release of GNOME is the System Settings window.  It is easily accessed from the…

The general idea is that new instances of the New Printer and Printer Properties dialogs, as well as a single instance of the…
