DigitalDJ is an SQL-based MP3-player frontend designed for people who want to create an MP3 version of their CD collection. It is designed to work with the Grip ripping/encoding application (but can be used separately). When Grip encodes MP3 files, it will place all of the song information into an SQL database. DigitalDJ can then use this information to create playlists based on a number of criteria.
Digicam is a simple and easy-to-use command-line utility to take, retrieve, and delete pictures from a Kodak DC21x camera. While the code is based on gphoto kodak_dc21x library, it fixes many annoying bug fixes in gphoto implementation, and allows for more options. Since digicam requires no user interaction and takes all the parameters from command line, it can be used in webcam-like scripts and for automatic image capture.
