PicoGUI aims to be a complete GUI environment for handheld computers and other embedded systems. It uses a client/server model, like the X window system, but while an X server is given raw drawing commands, the PicoGUI server integrates a widget set, making PicoGUI clients small and efficient. PicoGUI also has the goal of allowing client/server connections over a variety of mechanisms. It is most commonly used with Linux, but is designed to be portable to any OS. PicoGUI has a variety of video and input drivers which allow it to interface with the Linux framebuffer device, SDL, the X window system, and several other devices.
Device::ParallelPort is a Perl API that allows low level access to the parallel port of most computers. It does this by using a number of drivers, which can be customized and added to, including Linux (direct and parport), Win32, Script, Dummy, and more. It also contains a number of direct access devices including an example printer and a relay controller card.
The ArchivistaBox is a document management system (DMS) and archiving server. All required features are pre-installed and the implementation is kept to an absolute minimum. It features easy installation, a Web interface for both end users and administration, scanner integration, FTP scanning, PDF printing, backups, and OCR and PDF integration that allows the creation of searchable PDFs.
simena-io is a Linux tool written in Perl and designed to show ethernet interface statistics in bits/second and packets/second in real time. It requires at least Linux kernel 2.2 and Perl 5. It does not require a root account. There is only one command parameter: the refresh rate in seconds. If no parameter is provided, simena-io will refresh every 2 seconds by default. Detailed documentation can be obtained by running "perldoc simena-io".
