QP is a family of lightweight software frameworks for building responsive and modular real-time embedded applications as systems of cooperating, event-driven active objects (actors). The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, superbly documented, and commercially licensable. The behavior of active objects is specified in QP by means of hierarchical state machines (UML statecharts). The frameworks support manual coding of UML state machines in C or C++ as well as automatic code generation by means of the free QM modeling tool. All QP frameworks can run on bare-metal MCUs, completely replacing a traditional RTOS. Ports and ready-to-use examples are provided for all major CPUs, such as ARM Cortex-M, ARM7/9, MSP430, C28x, C55x, RX, R8C, AVR32, AVRMega, PIC24/dsPIC, as well as Arduino and mbed. QP/C and QP/C++ can also work with a traditional OS/RTOS, such as: POSIX (Linux, QNX), Windows, VxWorks, ThreadX, and uC/OS.
Mintty is a terminal emulator for Cygwin and MSYS with a native Windows user interface and minimalist design. It is based on parts of PuTTY by Simon Tatham and provides xterm-compatible terminal emulation, but does not require an X server. Its features include a simple options dialog, Unicode support, fullscreen mode, drag & drop, and window transparency.
FXiTe is an advanced cross-platform text editor built with the Fox GUI toolkit and the FXScintilla text widget. It features built-in syntax highlighting for 40+ languages, an embedded Lua scripting engine, macro recording and playback, multi-line regular expression search and replace, rudimentary ctags and calltip support, a flexible interface to external tools, and a built-in "message window" to capture the output of external commands such as compiler error messages, etc.
Eukleides is a computer language devoted to elementary plane geometry. It aims to be a fairly comprehensive system to create geometric figures, either static or dynamic. It can handle geometric types of data like points, vectors, lines, circles, or conics. A Eukleides script usually consists of a declarative part where objects are defined and a descriptive part where objects are drawn. Nonetheless, Eukleides is also a full featured programming language, providing conditional and iterative structures, user defined functions, modules, etc. The Eukleides distribution provides two distinct interpreters: "eukleides" and "euktopst". The former interpreter produces Encapsulated PostScript (EPS). The latter produces PSTricks macros, allowing Eukleides to be used with LaTeX.
UrBackup is an efficient client/server backup system for Linux and Windows. A client for Windows lets you backup open files and complete partition images. Incremental and full image backups are stored to disk in a efficient way with file level de-duplication on either Windows or Linux servers. An easy-to-use server Web interface lets you analyze storage usage, view logs, modify settings, and browse backups. Backup images can be restored using a prebuilt live Linux CD based on KNOPPIX.
The "Sound of Sorting" is a demo program containing many integer sorting algorithms. The algorithms are visualized in real time and augmented with sound effects, which are based on the values being compared. Animation speed and sound sustain can be customized while the algorithm is running. The visualization also highlights the algorithm's internal workings, which makes the demo program very useful for teaching sorting algorithms in an undergraduate computer science course. The program also counts the number of comparisons done by an algorithm, which can then be compared to the analytically derived value. The demo is implemented using the cross-platform toolkits wxWidgets and SDL, and can be executed on Windows, Linux, and Mac.
SITPLUS is a framework whose main goal is to provide ludic-therapeutic activities for people with disabilities. It offers new forms of interaction based on computer vision, voice, and other peripherals to produce a result in the form of image and sound. Inspired by the cause and effect applications, SITPLUS provides a tool for continuous and remote interaction, attainable by the majority of people with cognitive, sensory, and physical disabilities.
