KScannerButtons is a daemon plus an optional KDE frontend for monitoring your scanner buttons so that actions can be taken in response to button presses. It's composed of a daemon (sanebuttond), a frontend that will display an icon in the systray, and a dialog box to configure and launch the daemon. It is based on the button monitoring capabilities found in some SANE backends. It has been tested with the avision backend and an HP 5300C scanner. The frontend requires Kommander (kde-webdev).
fpcbol is a desktop user interface written for children and people who want simplicity and speed. It is designed to be as beautiful and simple as possible. It has no menus, just icons to click. It features parental control for children. It has been tested successfully on Debian, Mandriva, and Gentoo. It works well on computers with low system resources (such as a 500Mhz Pentium). 3D acceleration is necessary for the optional transparency feature.
Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.
The Advanced Bash Scripting Guide is both a reference and a tutorial on shell scripting. This comprehensive book, the equivalent of 1,032 print pages, covers almost every aspect of shell scripting. It contains 382 profusely commented illustrative examples, a number of tables, and a cross-linked index/glossary. Not just a shell scripting tutorial, this book also provides an introduction to basic programming techniques, such as sorting and recursion. Included scripts are the Game of Life, a Perquackey variant, a Morse code trainer, and an implementation of the Gronsfeld Cipher. This book is suited for both individual study and classroom use. It covers Bash, up to and including version 4.2. Note that users of miniaturized single-board computers running Linux, such as the Raspberry Pi and the Beagle Bone, would find this Guide useful for learning and running Bash scripts to explore and expand the capabilities of these small, but powerful machines.
