AudioScope is a text mode audio oscilloscope that captures sounds using DEMO, SOX, or DSP (/dev/dsp}. It is primarily a learning tool for kids. The script includes code and circuit diagrams for calibrating the horizontal and vertical axes. It features a demo mode with no dependences that samples /dev/urandom.
SWATnalysis is a utility that runs the Soil and Water Assessment Tool (SWAT) and analyzes its output files. It converts archaically formatted SWAT output files into more user friendly CSV files, performs graphical analysis, calculates area weighted precipitation values, and performs statistical analysis of observed data versus simulated data.
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.
