Basenji : A media indexing tool designed for easy and fast indexing of media collections

Basenji is a media indexing tool designed for easy and fast indexing of media collections. It currently supports indexing of removable media such as CDs and USB sticks and stores them as volume objects in a database. After being stored in this database, volumes can be browsed and searched through for specific files very quickly. Basenji has been developed with platform independence in mind right from the start, and presently consists of a GTK+ GUI frontend and a reusable library backend (VolumeDB) that implements the actual indexing, searching, and database logic.

Paperkey : An OpenPGP key archiver

Paperkey is a reasonable way to achieve a long term backup of OpenPGP (GnuPG, PGP, etc) keys is to print them out on paper. Due to metadata and redundancy, OpenPGP secret keys are significantly larger than just the "secret bits". In fact, the secret key contains a complete copy of the public key. Since the public key generally doesn't need to be backed up in this way (most people have many copies of it on various keyservers, Web pages, etc), only extracting the secret parts can be a real advantage. Paperkey extracts just those secret bytes and prints them. To reconstruct, you re-enter those bytes (whether by hand or via OCR), and paperkey can use them to transform your existing public key into a secret key.
