Karin detects and deletes commercials from video files captured off television. It currently uses black frame detection, volume detection, logo detection, audio fingerprinting and time analysis to determine what segments of a video file are commercials. Plans for the future include a linux port, a scripting interface, a central fingerprint server, and image matching.
OpenPGP Webmail is a set of PHP scripts which allows anonymous Web users to send encrypted email to anyone with PGP or GPG keys. It is designed to run over SSL, and has a key search facility built in. GnuPG is required to do the encryption. The project is now abandonware. Anyone can take it over if they like.
