pthread-lib is a set of pthread wrapper functions, a thread manager, and a signal handler. The wrapper functions enable the programmer to create and manage sets of thread pools without knowing all the pthread internals. This includes creating, joining, and other operations. The thread manager watches and supervises the threads, checking whether they are still alive and working. The thread manager can also be assigned tasks by the programmer, either in code or by a configuration file. These tasks will be executed when the scheduled date/time occurs, and can be almost any task. The thread manager is implemented as its own thread within the main process. A single-threaded signal handler is available to catch all signals to a multi-threaded process. Instead of having every thread manage signals, this one thread handles all signals. To further enhance its functionality, the programmer is allowed to assign functions (via a pointer to a function) to any signal it may catch.
reacTIVision is a computer vision framework for the fast and robust tracking of fiducial markers attached to physical objects, as well as for multi-touch finger tracking. It was mainly designed as a toolkit for the rapid development of table-based tangible user interfaces and interactive multi-touch surfaces such as the reacTable. Client application examples are available for various programming environments such as C++, Java, C#, Processing, PureData, Max/MSP, and Quartz Composer.
Regular Expression Builder for Java (reb4j) is a simple set of classes that encapsulates the regular expressions used by java.util.regex.Pattern and provides facilities for composing larger expressions from sub-expressions. It effectively provides a way to build regular expressions without the risk of encountering PatternSyntaxExceptions at runtime.
