PyMP3Cut is a Python command line tool designed to cut huge (> 100MB) MP3 files at high speed without requiring the extra disk space and processing time usually needed by visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything. It reads and cuts simultaneously according to the autodetected MP3 frame rate and a timeline passed as a command line argument. It doesn't currently deal with Variable Bit Rate (VBR) MP3 files, though.
Tux Paint is a simple and entertaining drawing program geared towards young children. It has a simple interface, sound effects, and a cartoon character (Tux, the Linux penguin). Along with drawing brush strokes, lines and shapes, you can also enter text and place "rubber stamp" (or "sticker") images on the picture. Tux Paint is extensible, and could be useful in an educational environment (such as a grammar, elementary, or grade school). It's portable across numerous platforms, and runs well even on slower systems like the Pentium 133MHz.
Grammidity is a Java based framework for evolutionary programming based on grammars. It can be used to evolve solutions to problems, or to evolve "objects" under user control. It has a limitless range of possible applications. This program has been tested on sample projects generating 3D objects and imitation plants.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
DJFractal is yet another fractal generator which distributes fractal data to multiple computers. Fractal data are created locally and distributed to other computers that run the appropriate fractal-generation software, which may be hosted on workstations, or on a Java enabled Web-browser through applets, or on a system with JavaCard. DJFractal's unique feature is the "smart" algorithm it uses to compute (and draw) the most interesting part of a fractal first.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
LXlogo is an interactive LOGO programming environment for K-12 educational use or just for fun. It is easy to install with minimal system requirements, and is a modern variant of the familiar "turtle" LOGO language. Logo is interesting because it gives students immediate graphical results with just a few commands or lines of code, and allows students to gradually become familiar with geometric concepts, and how to write programs and think procedurally. As students move beyond the beginning stages, they can move on to create fun animations and user interfaces.
Frocor, the F Resonating Objects Correlator, is a sound- graphics installation. It is based on some parallels between sounds and geometric objects, such as volume and size, frequency and color, etc. Changes of properties of a Frocor object will result in changes of both the graphics and the sound output.
