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.
Xvisor is a type-1 hypervisor that aims to provide a monolithic, light-weight, portable, and flexible virtualization solution for ARMv5, ARMv6, ARMv7a, x86_64, and other CPU architectures. It primarily supports full virtualization, and hence supports a wide range of unmodified guest operating systems. Paravirtualization is optional and is supported in an architecture independent manner (such as VirtIO PCI/MMIO devices) to ensure that no changes are required in the guest OS.
Cedar Backup is a software package designed to manage system backups for a pool of local and remote machines. Cedar Backup understands how to back up filesystem data as well as MySQL and PostgreSQL databases and Subversion repositories. It can also be easily extended to support other kinds of data sources. Cedar Backup is focused around weekly backups to a single CD or DVD disc. It supports multisession discs, allowing you to add incremental data to a disc on a daily basis. Cedar Backup also provides a Python library of backup-related functionality.
SyncWall is a basic wallpaper changer with a special feature, the ability to synchronize wallpaper changes between several workstations with a basic (and unsecured) client/server protocol. Each workstation must share the same pool of files, there is no FTP or Internet download. Other interesting features are simple multi-monitor support and the ability to add special effects to wallpaper.
repla can turn any command into a shell. It does this by prepending the name of a command to each commandline before executing it. It can also add lists of arguments which are often needed, either prefixed or affixed to the commandline. It really shines with vcs or build commands, such as git, svn, hg, make, configure, etc.
kgrep searches through a file or files for a specified pattern and displays the target line containing the pattern as well as a certain number of lines on either side of the target line. GNU grep can do this with the -A, -B and -C switches, and other platform-specific grep implementations may have similar functionality. The main advantage to kgrep is that it's small and can be easily used on any system that has Perl5 installed, rather than going through the hassle of installing a different grep binary (this is actually what the author uses it for most often).
