Rhythmbox provides tool to control running instance from terminal, which is very good feature. With it's help it is very easy to create a widget which displays currently playing song. Also here I'm showing how to add some shortcuts to control music.

Very simple widgets for Awesome - battery widget which shows status of the battery and also includes a popup message when you have less than 15% of power left and a volume widget which shows an icon which represents the sound volume.

AppDynamics is platform which allows to monitor many aspects of the application - from user interaction to performance of SQL calls to database. It has nice platform for custom extensions which provides all kind of metrics.

I would like to share some of SQL queries for Alfresco database which could be useful.
