The Blender-Mathutils module originated from Blender, where it has been used for some years in production as a utility module for use in areas including animation, games, and mesh manipulation. This differs from 'numpy' in that it is computer graphics focused, combining Matrix and Vector types with rotation classes, which is very useful for use with animation or anywhere Euler and Quaternion values are frequently used. This project is mainly a build system around the actively maintained mathutils code in Blender to allow non-Blender related projects to make use of it. A link to the Blender repository is used so that the source never gets out of sync.
Fast File Validator (FFV) is a program for verifying files against a checksum file and for creating such checksum files. FFV supports both SFV files (which use the CRC32 algorithm) and MD5 files. "Checksum" is meant in the generic sense here. Technically, neither CRC32 nor MD5 is really a checksum.
Relax-and-Recover (Rear) is a bare metal disaster recovery and system migration solution, similar to AIX mksysb or HP-UX ignite. It is composed of a modular framework and ready-to-go workflows for many common situations to produce a bootable image and restore from backup using this image. It can restore to different hardware, and can therefore be used as a migration tool as well. It supports various boot media (including tape, USB, or eSATA storage, ISO, PXE, etc.), a variety of network protocols (including SFTP, FTP, HTTP, NFS, and CIFS), as well as a multitude of backup strategies (including IBM TSM, HP DataProtector, Symantec NetBackup, Bacula, and rsync). It was designed to be easy to set up, requires no maintenance, and is there to assist when disaster strikes. Recovering from disaster is made very straight-forward by a 2-step recovery process so that it can be executed by operational teams when required. When used interactively (e.g. when used for migrating systems), menus help make decisions to restore to a new (hardware) environment.
SIMPLE-MTPFS (Simple Media Transfer Protocol FileSystem) is a file system for Linux (and other operating systems with a FUSE implementation, such as Mac OS X or FreeBSD) capable of operating on files on MTP devices attached via USB to local machine. It allows the end user to seamlessly interact with MTP device files.
