SNOW is a utility for concealing messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, messages concealed with whitespace are effectively hidden from casual observers. If SNOW's built-in encryption is used, the message cannot be read even if it is detected. SNOW exploits the Steganographic Nature Of Whitespace, similar to finding a polar bear in a snowstorm; hence the name.
CDimg|tools is a set of commandline tools to inspect and manipulate CD/DVD optical disc images in formats uncommon on free Unix-like systems (like GNU/Linux or BSD). It makes it possible to convert .NRG Nero images, to demultiplex RAW+96 image files containing both stream data and sub-channel data, to decrypt CSS-scrambled VOB files, and to decrypt CSS-scrambled DVD Video image files.
GTKMathplot is an interactive plotting program based on GTK+ and the Cairo graphics library. It can display bidimensional curves, tridimensional curves, and surfaces from Cartesian or parametric equations describing the mathematical objects you would like to visualize. It is designed to be intuitive for high school students with good mathematical knowledge. University students of engineering, physics, mathematics, or natural sciences should need no explanation at all to start using it proficiently.
malloc_count provides a set of source code tools that measure the amount of memory allocated to a program at run-time. The code library provides facilities to measure the current and peak heap memory allocation, and write a memory profile for plotting. Furthermore, separate stack_count functions can measure stack usage. The code tool works by intercepting the standard malloc(), free(), etc. functions. Thus no changes are necessary to the inspected source code.
Limbo is a PC Emulator (x86) based on QEMU for Android devices. It lets you run a Desktop OS like Debian or DSL Linux on your Android device with Network and X Windows. Limbo works with Live CD ISOs and pre-installed hard disk images created with QEMU, VMWare, Bochs, or Virtual PC emulators.
