Watson

Watson, the revolutionary answering machine from IBM that beat a human in TV show Jeopardy! is build on SuSE Linux and uses lots of free software. Take a look to the keynote below. Starting from minute 10:00 a general presentation of Watson starts, then later on Grady Booch describes the architecture of the system.
It’s also described on wikipedia.

List DBus installed services

If, like me, you’re wondering if the shining new DBus service you written is correctly recognized by the DBus daemon, then issue this command:

> qdbus org.freedesktop.DBus / ListActivatableNames

You’ll get an output like this one:

org.freedesktop.DBus
org.freedesktop.Notifications
org.kde.fontinst
org.gnome.GConf
org.freedesktop.Akonadi.Control
org.gtk.vfs.Metadata
vandenoever.strigi
org.kde.kuiserver
org.gtk.Private.AfcVolumeMonitor
org.gnome.GnomeVFS.Daemon
org.kde.knotify
org.gtk.vfs.Daemon
org.freedesktop.xesam.searcher
org.openobex
org.freedesktop.secrets
org.gtk.Private.GduVolumeMonitor
org.gtk.Private.GPhoto2VolumeMonitor
ca.desrt.dconf
org.kde.krunner

All these names come from the .service files installed on your system and recognized by the dbus-daemon.
