sipsak is a command line tool for performing various tests on Session Initiation Protocol (SIP) applications and devices. It can make several different tests, send the contents of a file, and interpret and react on the responses. It supports (de-) registration with given contact URIs and digest authentication.
Learning Management System allows users to manage online learning classes. It allows them to set up classes, create assignments online, and send messages to students from within the system for tracking. It is a simple system to move academic classes onto the Web in order to reach a larger audience.
The Discrete Event Calculus Reasoner allows a programmer to add common-sense reasoning capabilities to programs. It supports deduction/temporal projection, abduction/planning, postdiction, and model finding. It allows default reasoning about action, change, space, and mental states. It is based on the event calculus, a comprehensive and highly usable logic-based formalism. It helps applications understand the world, make inferences, adapt to unexpected situations, and be more flexible.
XCircuit is a UNIX/X11 program for drawing publishable-quality electrical circuit schematic diagrams and related figures, and producing circuit netlists through schematic capture. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE netlists. Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit does not separate artistic expression from circuit drawing; it maintains flexiblity in style without compromising the power of schematic capture.
imgSeek is a photo collection manager capable of searching through an image database, in which the query is expressed either as a rough sketch painted by the user or as another image you supply. You simply draw a rough sketch of what you want to find and imgSeek displays for you a thumbnail view of the best matches. You may also find duplicate images automatically, generate Web photo albums, edit image metadata including EXIF JPEG data, organize images into a keyword hierarchy, and more.
Arduino is a physical computing platform based on a simple micrcontroller board and a development environment that implements the processing language. It can be used to develop stand-alone interactive objects or can be connected to software on your computer such as Flash, Processing, MaxMSP, PD, or VVVV.
