Oww (One-Wire Weather) is a client program for Dallas Semiconductor / AAG 1-wire weather station kits, providing a graphical (animated) display to monitor outside temperature, wind speed and direction, rainfall, and humidity. Extra temperature sensors may be added. A 1-wire "hub" may be used for improved reliability and range. Weather data may be logged to CSV files, parsed to command line programs, sent to the Henriksen Windows client, or uploaded to Web servers at Dallas, The Weather Underground, and HAMweather.
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.
The Date::Calc package consists of a (pure-Perl) wrapper which either loads Date::Calc::XS (a separate implementation in C and XS) or Date::Calc::PP (a pure-Perl implementation which is part of the Date::Calc package). The Date::Calc::XS and Date::Calc::PP modules perform all kinds of date calculations based on the Gregorian calendar (the one used in all Western countries today), according to relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent, ISO 8601 (where applicable). The package is designed as an efficient toolbox, not a bulky ready-made application. It provides extensive documentation and examples of use, multi-language support, and special functions for business needs.
Radiance is a set of tools which provide an advanced lighting simulation software package. It allows very detailed definition of materials' and light sources' properties through the use of advanced techniques like brdf and ies files, as well as a powerful mathematical scripting language, resulting in accurate renderings of scenes which are usually imported from CAD and 3D modelers. It uses the hybrid approach of Monte Carlo and deterministic ray tracing to achieve a reasonably accurate result in a reasonable time.
Evolvica is an evolutionary computation framework written in Java. The aim of the project is to provide a toolkit that enables developers to create genetic/evolutionary algorithms with minimal programming effort. The toolkit has a modular architecture and is highly extensible. It includes a visual algorithm editor, a source code editor, and a debugger.
The PerlDL project aims to turn Perl into an efficient numerical language for scientific computing. The PDL module gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data sets which are the bread and butter of scientific computing. e.g. $a=$b+$c can add two 2048x2048 images in only a fraction of a second. The aim is to provide tons of useful functionality for scientific and numeric analysis.
OpenBeacon is a open and generic design for an active wireless transceiver device hardware that operates in the 2.4GHz ISM band. The tag contains a unique serial number, but may have other information like acceleration measurement. The OpenBeacon tag is designed as a transceiver device, and therefore both transmits and receives radio waves. The intention of this project is to offer a wide range of use cases such as visitor or item tracking and wireless remote control with a free self-contained and low-cost RFID design. It enables wireless remote control application and ultra low power wireless meshing nodes.
libkdtree++ is a C++ template container implementation of k-dimensional space sorting, using a kd-tree. It sports a theoretically unlimited number of dimensions, and can store any data structure. Provided the data structure, it provides operator[0 - k-1] to access the individual dimensional components (arrays, std::vector already do) and a std::less implementation for the type of dimensional components. It has support for custom allocators, implements iterators, and provides standard find as well as range queries. It has amortised O(lg n) time (O(n lg n) worst case) on most operations (insert/erase/find optimised) and worst-case O(n) space, and also provides a means to rebalance and thus optimise the tree.
