The Advanced Bash Scripting Guide is both a reference and a tutorial on shell scripting. This comprehensive book, the equivalent of 1,000+ 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.
cproto generates function prototypes for functions defined in the specified C source files to the standard output. The function definitions may be in K&R or ANSI C style, or in the lint library form. cproto can also convert function definitions in the specified files from the K&R style to the ANSI C style.
The National Space Science Data Center's (NSSDC) Common Data Format (CDF) is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion. It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
The TkinterTreectrl module wraps the treectrl Tk extension for use with Python/Tkinter. The treectrl widget allows you to create fancy things like sortable multi-column list boxes and hierarchical tree views in Tkinter. The package also includes a ready to use multi-column listbox widget, scrolled Treectrl, and multi-column list box widgets plus a generic ScrolledWidget class that makes it quite easy to add one or two static or automatic scroll bars to any listbox-alike Tkinter widget.
