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.
GetData is a library that provides an API to interface with dirfile databases. The dirfile database format is designed to provide a fast, scalable format for storing and reading binary, synchronously-sampled, time-ordered data. GetData was originally written for the BOOMERanG and BLAST experiments as a data format suitable for use for both quick-look and data reduction. It is now used by many other cosmological and astrophysical experiments including ACT, Planck, Spider, Keck, as well as other projects.
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.
nts is an acronym for Note Taking Simplified. It provides a simple, intuitive format for using plain text files to store notes, a command line interface for viewing notes in a variety of convenient ways, and a cross-platform, wx(python)-based GUI for creating and modifying notes as well as viewing them. Displayed items can be grouped by path or tag and can be filtered in various ways.
The qpfcalc application is a Qt frontend for pfcalc, a CLI pipe friction calculator. It is similar to gpfcalc, the GTK+ frontend for pfcalc. There are two versions of qpfcalc, one for Windows and one for Linux. The Linux version should be easy to compile and run on any Unix-like operating system with few minor modifications. For the application to function properly the pfcalc backend must be installed. For the Windows version, this is not needed as qpfcalc is distributed along with all the files needed to run, including pfcalc and Qt libraries.
Grapple is designed to be a simple network layer, allowing the addition of multiuser features to an application for as little as a dozen lines of code. However, it also allows for more. It features simple client-server networking that keeps all clients aware of all other clients, passworded servers, and data transfer via TCP, UDP, or reliable UDP. Advanced features include network messaging via push, pull, or a combination, multiple methods of querying users, user groups for client bandwidth saving, network load reacting data transmission and retransmission, background pinging to monitor network states, server failover, and a fully functional lobby system.
The Brick Engine is a fast and simple lo-fi gaming engine. The engine provides a comprehensive API, including dazzling visual features, song playback, and collision detection: everything you need to make games with quickness and ease. The engine provides a straightforward C API and has language bindings for Tcl and Pascal, with support for more languages on the way.
