ZoneMinder is a suite of applications intended for use in video camera security applications, including theft prevention and child or family member monitoring. It supports capture, analysis, recording, and monitoring of video data coming from one or more video or network cameras attached to a Linux system. It also features a user-friendly Web interface which allows viewing, archival, review, and deletion of images and movies captured by the cameras. The image analysis system is highly configurable, permitting retention of specific events, while eliminating false positives. ZoneMinder supports both directly connected and network cameras and is built around the definition of a set of individual 'zones' of varying sensitivity and functionality for each camera. This allows the elimination of regions which should be ignored or the definition of areas which will alarm if various thresholds are exceeded in conjunction with other zones. All management, control, and other functions are supported through the Web interface.
SecureSkat is a peer-to-peer implementation of the German card game Skat. The program negotiates participating players and game sessions over an arbitrary IRC network (Internet Relay Chat). Neither a trusted third-party (dealer) nor a centralized game server is necessary. All critical operations, e.g. shuffle of the deck, are performed using advanced cryptographic techniques (so-called Mental Poker solutions) provided by LibTMCG. The outdated OpenSkat branch contains a graphical user interface based on XSkat 3.4. This interface can be used with most recent versions, but must be built separately.
cpm (Console Password Manager) is a small console tool to manage passwords and other sensitive data and store them in a public-key encrypted file. It also allows you to configure the whole hierarchy yourself, so it's easily adoptable for many requirements. The encryption is handled through GnuPG, and the data inside is stored as XML.
