EPOR is an extensible package organiser for Unix-like systems. It's written to trace filesystem changes (something being installed) and save this information in a simple text database (this, as any other provided feature, is customisable via the embedded Guile interpreter). Database entries contain information supplied by the command line (package name, version, etc.) and traced by filesystem changes (new directories, files, etc.). This is achieved using the "LD_PRELOAD method''.
Thinux is a thin-client server on a live CD. It boots a network of diskless computers to automatically start an application such as a Web browser. Each thin client machine acts as a cluster node to share its processing and memory resources with each other to take the load off the server. It is a turnkey solution that does not change nor rely on your existing systems to run. By booting from a removable CD, it does not lock-in the user so it is convenient to test. It is ideal for any organizations that require large deployment of software automatically and cost effectively.
Linux device driver for CueCat barcode readers that supports multiple PS/2 CueCats on either the keyboard port, mouse port (without disabling the mouse) or USB port through a PS/2 -> USB adapter, or native USB CueCats. A standalone application that doesn't require the driver and also reads barcodes from a CueCat connected to a serial port through a homemade PS/2 -> serial converter is included as well. The driver separates CueCat barcode scancodes from normal keyboard or mouse scancodes, decode the barcodes, performs error-checking on them and send them in clear text through a normal character device file. NOTE : the company that created the CueCat has disappeared. CueCat readers are no longer produced or distributed.
Kernin is an easy-to-follow, menu-driven script to help with the installation of a Linux kernel.

Kernin is mainly aimed at inexperienced users that have no prior knowledge of kernel installation. Kernin can also help experienced Linux users save time when installing a kernel. Note that kernin is only compatible with LILO at the moment.
