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.
Arachne is program that implements Avidan and Shamir's seam carving technique for content-aware image resizing. It allows realtime, fluid image resizing using this fascinating technique. Seam carving works by removing the "boring bits" from an image, so it can change the aspect ratio of many images without changing the shape of the objects inside.
ArtistX is a live DVD which turns a computer into a full multimedia production studio. It is based on Debian GNU/Linux and contains nearly all the available free audio, 2D and 3D graphics, and video software for the GNU/Linux computing platform. It doesn't need to be installed, and boots directly into a running system without touching hard drives. The files produced with ArtistX can be easily stored on a USB card or CD/DVD medium while it is running.
This package can be used to implement aspect oriented programming (AOP) by executing the code of classes that enable orthogonal aspects at run- time. The intention is to provide a means to implement orthogonal aspects in separate classes that may be an interesting add to the application, like logging, caching, transaction control, etc., without affecting the main business logic. The package provides base classes for implementing defining point cuts where the code of an advice class is called to implement actions of the orthogonal aspects that an application may need to enable.
Aubit 4GL compiler is a programming language based on (and compatible with) Informix-4GL. It provides an easy way to generate screen/form based programs, since statements for handling Windows, Forms, Menus, SQL, and similar are built-in. With support for SQL statements forming an intrinsic part of the language, it's especially suitable for developing database-oriented applications. Database connectivity is provided for PostgreSQL, MySQL, Informix, and others via ODBC. It supports both ncurses (console mode) and GTK+ (GUI mode) output.
The CDAY Calendar Almanac displays historical anniversaries such as birthdays and general events. It displays the equivalent date in multiple calendar systems, including Hebrew, Julian, JDNs, Great Underground Empire (Zork), Shire (Lord of the Rings), and Star dates. Separate GUI, command line, and Web-based versions are available, along with free libraries of thousands of events.
Check is a unit test framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so Check can catch both assertion failures and code errors that cause segmentation faults or other signals. The output from unit tests can be used within source code editors and IDEs.
