slkvm is an application to provide some system tools to work with clustering and virtualization. It focuses on depending on as few external tools as possible but to also support as many virtualization technologies as possible. It works in a cluster environment where heartbeat runs virtual machines of nodes that have failed. It builds an "unheaded" cluster to avoid having a clear point of failure. It is able to build a two node cluster with everything redundant. It avoids compiling a new kernel or newer version of applications, so you can benefit from Debian security updates.
debshare.create is a hackish script used for producing .debshare files, which are basically "self-executable", monolithic archives containing several .deb packages. A .debshare file is meant to install one (or more) applications that it contains, complete with all its dependencies. This facilitates easy sharing of applications across computers using a single file, as opposed to multiple .deb packages. This idea was originally meant for Ubuntu systems, but there should be no reason why it shouldn't work on other similar distributions. Technically, a .debshare file is a bash shell script with a binary payload (a tar archive with the .deb-s) appended to it.
The Teleport command is a replacement for the traditional cd command. More accurately, it's a wrapper around the cd command, with various improvements. It keeps a history of the directories you have visited. You can easily jump to any directory in your history. You can display your history. You can easily create aliases for directories to make it even easier to jump to them.
CryptBackup is an encrypted backup application for Linux desktop users. It allows even a layperson to backup their home directory (including the desktop) on an encrypted external device with just a few clicks. Even the setup is only to choose the external device (such as an external hard drive) and to set a password.
The Hungarian algorithm solves the assignment problem. It was developed by Harold Kuhn and reworked by James Munkres, and so it is also known as the Kuhn-Munkres algorithm. Kuhn-Munkres is used inside assignment problem solver applications. An instance generator application creates an input file for the solver. A checker application verifies the solution computed by the solver. A bash script compiles and executes these apps.
