Grifcat is a simple utility which monitors a Griffin Powermate and sends state change information to the calling script. It tracks the button and wheel motion, reporting each move as it occurs and accumulating net changes in both directions. It is convenient for script writers and those looking for an easy way to integrate the powermate into their applications via a simple coprocess. Grifcat uses libusb to access the USB in a platform independent manner.
grzip is a high-performance file compressor based on Burrows-Wheeler Transform, Schindler Transform, Move-To-Front, and Weighted Frequency Counting. It uses the Block-Sorting Lossless Data Compression Algorithm, which has received considerable attention in recent years for both its simplicity and effectiveness. This implementation has a compression rate of 2.234 bps on the Calgary Corpus (14 files) without preprocessing filters. This is essentially an adaptation/extension of GRZipII by Ilya Grebnov.
