PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension.
TimeIT is a time tracker that works quietly almost without any interaction and still measures the time you are spending on several projects. The concept of this program is that tasks and projects are assigned to workspaces and while you are in those workspaces your projects are timed. It also has detection of idleness, editing of time records, and summary views grouped by day, week, month, and year.
Processdsn consumes RFC 3464 delivery status notification email messages, writing a summary of the notification to a SQL database. Notifications may indicate successful delivery, a delay in delivery, or delivery failure. The database is designed to be exposed restfully by the mod_processdsn module for Apache httpd, but can queried directly if necessary.
