Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz) able to repair slightly damaged files, recover badly damaged files from two or more copies, extract data from damaged files, decompress files, and test integrity of files. Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip, and pdlzip. It makes lzip files resistant to bit-flip, one of the most common forms of data corruption, and its recovery capabilities contribute to make of the lzip format one of the best options for long-term data archiving.
The OATH Toolkit makes it easy to build one-time password authentication systems. It contains shared libraries, commandline tools, and a PAM module. Supported technologies include the event-based HOTP algorithm (RFC4226) and the time-based TOTP algorithm (RFC6238). OATH stands for Open AuTHentication, which is the organization which specifies the algorithms. For managing secret key files, the Portable Symmetric Key Container (PSKC) format described in RFC6030 is supported.
Plzip is a massively parallel (multi-threaded), lossless data compressor based on the lzlib compression library, with a user interface similar to the one of lzip, bzip2, or gzip. It can compress/decompress large files on multiprocessor machines much faster than lzip, at the cost of a slightly-reduced compression ratio. (Note that the number of usable threads is limited by file size). Plzip uses the lzip file format, and the files produced by plzip are fully compatible with lzip-1.4 or newer, and can be rescued with lziprecover.
Pybik is an interactive, graphical, single player puzzle about the cube invented by Ernő Rubik. Besides the cube, the program can handle towers and bricks (non-cubic puzzles). Pybik also has solvers, pretty patterns, and a collection of various moves. The cube can be manipulated with the mouse or keyboard. You can change the colors or images on the faces of the cube.
