Spectra is a simple tool designed to aid in evaluating the quality of random numbers generated by TRNGs and PRNGs. It does this by counting the occurrences of characters within a given input file to help detect perceived bias, and then visualizes the data as colored (or black and white) pixels in an image file to aid in detection of repeating patterns. As the human mind is exceptionally good at picking up on patterns that might otherwise be difficult to detect mathematically, Spectra allows the user to rapidly make a determination on the repeatability of numbers generated from the suspect RNG.
METAMOD is a portal solution providing Discovery, Access and Retrieve functionality for scientific datasets along with tools for DAR metadata like automatic extraction, manual editing, and conversion between different formats. Metadata can be converted to different formats and exposed using different search interfaces, i.e. ISO23950 and OAI-PM. It has been designed to be easily integratable with OpENDAP or FTP data servers, and allows data to be uploaded through FTP and HTTP interfaces. A WMS client is built in for visualizing the data.
din is a software musical instrument and audio synthesizer. Bezier curves are used to draw and sculpt waveforms, create gating and modulation (FM and AM) patterns, and create delay feedback and volume patterns. You can also create an unlimited number of drones and sculpt their waveforms. It uses JACK to output audio, and supports MIDI, OSC and IRC bot for input. din can be extended and customized with Tcl scripts.
bgt is a program for creating and maintaining a budget from the UNIX/Linux command line. It is written in ANSI C. For number processing, it uses the Binary Coded Decimal number engine from bc. For data storage, it uses SQLite. All functionality for the program is available from the command line and does not require a GUI. It should be portable to other environments, including Windows, but it uses Unix-only directory names, so it would need some tweaking.
OpenClass is a simple solution for class control. It provides multicast screen projection (sending the teacher's screen to all of the students), student attention requests (blocking student activities and asking them to look at teacher), viewing of all student screens at once, direct messaging to students, file and URL sharing, computer shutdown, access control for specific classes, and support for multi-seat configurations and multiple clients per machine. For students it provides automatic teacher discovery via broadcast, "raise hand" functionality, and automatic handling of network saturation and disconnection events.
