izBalancing is a bash script featuring an in/out multi-homed load-balanced Internet gateway traffic manager with a failover facility. It features multiple balanced default gateway configurations, load-balanced outgoing connections from LAN to Internet connections, and management of multiple incoming connections from many Internet ISP lines to DMZ/LAN Servers. It is a SystemV compliant script, and can be easily run at boot. It will automatically discover your local IP addresses. You can cleanly start and stop your multi-homed configuration with a simple command (izbalancing start|stop|restart). Adding new Internet connections is very fast and easy: you need only provide the interface name, router IP address, and a descriptive name. If the izping daemon is installed into /etc/rc.d/init.d/, it will be used for automatic failover and recovery of Internet lines.

Ferret is a copy-detection tool, locating duplicate text or code in multiple text documents or source files. It is designed to detect copying (collusion) within a given set of files. Ferret is useful for document analysis, tracking changes to or reuse of text in documents; for software developers, looking for duplicate code to refactor; in software evolution, studying how code has changed over time; for teachers, looking for collusion or plagiarism in student work; and for tracking the amount of new material in the current version of a text or program.
