Spindown is a daemon to spin down idle disks and thus save energy and give the disks a longer lifetime. It also works with USB disks and hot-swappable disks because it uses the device ID to identify the disk instead of the device name (such as hda or sdb). This means that it doesn't matter if the disk is swapped while the daemon is running.
Multiple Devices Proxy is an application proxy to communicate with pipes, serial ports (RS-232/RS-485), TCP/IP, and potentially all devices in a host computer via TCP/IP sockets. It supports multicast and communication isolation. Any server may have many resources, e.g. 2 pipes, 4 RS-232, and 2 connected sockets to another server. Clients may ask for 1 to many of these resources, and all data will be multicast.
Gargoyle is an interface for small, widely available routers such as the Linksys WRT54G series and the La Fonera. It provides functionality above and beyond what the default software provides including sophisticated dynamic DNS, quality of service, and bandwidth monitoring tools. The primary goal is to provide a polished interface for these advanced tools that is at least as easy to configure as any existing firmware. This project is based on top of OpenWrt, but unlike other Web interfaces for OpenWrt it places a strong focus an usability and is meant for average users, not just power users.
Cerberus-Prox is backend software for an inexpensive, easy-to-build hardware system that implements a functional door access control system. It supports HID clock-and-data prox card readers. A MySQL database (or theoretically any JDBC) is used for data storage. RXTX is used for serial port communication.
