pyReScene is a tool that recreates original RARs by backing up the metadata. It is a port of ReScene .NET to Python. It provides a mechanism for backing up and restoring the metadata from "scene" released RAR files. RAR archive volumes are rebuilt using the stored metadata in the SRR file and the files extracted from the RAR archive. pyReScene consists of multiple related tools: pyReScene Auto to create a complete SRR with one simple command, pyReSample to recreate sample files, and pyReScene Usenet to create SRR files on the fly from Usenet postings. Lots of other small scripts for managing SRR and SRS files are available too.
Ferret is a copy-detection tool, locating duplicate text or code in multiple text documents or source files. It is designed to detect copying (collusion) within a given set of files. Ferret is useful for document analysis, tracking changes to or reuse of text in documents; for software developers, looking for duplicate code to refactor; in software evolution, studying how code has changed over time; for teachers, looking for collusion or plagiarism in student work; and for tracking the amount of new material in the current version of a text or program.
Galois is a computer game of the "falling blocks" type, but with unique features. Unlike most other games of that type, it is not limited to blocks made of four two-dimensional, square bricks: you can choose among several different brick shapes, blocks composed of more or fewer bricks, and even between two- and three-dimensional games.
cQRCode is a class that generates QR code images in GIF, JPEG, and PNG formats. It takes a string of information to encode and can either serve the image with the current script output or save it to a file. The size of matrix points and the error correction level parameters are configurable.
