Calc is arbitrary precision arithmetic system that uses a C-like language. It's useful as a calculator, an algorithm prototype, and as a mathematical research tool. More importantly, calc provides a machine-independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions.
CDSA stands for Common Data Security Architecture. It provides a security framework that includes cryptographically signed modules to present an abstracted unified API to the application developer to perform cryptographic and security related operations. It also includes hardware support for cryptographic tokens and biometric devices, such as thumbprint scanners. Intel has implemented the CDSA 2 specification and released it as open source.
VIrus (VI resembling utility skeleton) was originally taken from busybox and stripped of most unrelated stuff. The intention is to provide a pure, minimalist VI implementation that allows you to switch off shell-escaping and other security risks by default, and allow the admin to offer an interim user to just have a vi as login-shell on a certain host, while allowing others to work with a resource-sensitive and small vi implementation for your OS bootdisks.
jGRASP integrates the Control Structure Diagram (CSD) seamlessly and unobtrusively into source-code editing for Java, C, C++, Objective-C, Ada, and VHDL. The CSD is a control flow and data structure diagram that fits into the space normally taken by indentation in source code. Its intention is to improve the readability of source code. The CSD also enables source code folding in a meaningful way, based on code structures. jGRASP provides lots of editing features, an integrated Java debugger, UML dependency diagrams for Java, configurable colors and font size, and click-to-error for compile and runtime (Java stack dumps) errors.
tif22pnm is a command line utility that converts between TIFF sampled images and PNM images (both directions), using the libtiff library, but not using NetPBM. tif22pnm is similar to the tifftopnm utility in the NetPBM distribution, but tif22pnm handles a wider range of TIFF files and is able to output the alpha channel as a PBM or PGM file. png22pnm, a converter from PNG to PNM, is also bundled into the distribution.
Chump is a table-driven assembler and dissembler with a very fast new architecture input format. Both the assembler and disassembler are created using a single description. It comes with descriptions for ARM, MIPS, Stump, and 6809. It is intended for use as a library compiled with other programs to allow line assembly and disassembly.
BitLife is an implementation of life using boolean operations (AND, OR, XOR), computing each new cell from 9 bits (itself & neighbours). It's performed in parallel on the whole image by bitblit operations (with hardware accelearation where possible). This also allows many parallel life games to run in each bitplane of the screen, giving a translucent blending effect. A proof-of-concept Python (pygame/Numeric) implementation and an xscreensaver hack are included.
