peekabot is a versatile 3D visualization tool targeted at robotics researchers and developers. It's multi-platform, general purpose, easily extendable, scalable, and does not depend on any other frameworks to function. It also provides some functionality for interacting with your robots using the GUI. You can test your algorithms in both simulated and real environments. The only requirement is that the device can use TCP/IP.
wxFreeChart is powerful charting library based on wxWidgets. It is designed with flexibility in mind, and supports many types of charts with many different configurations. These include line/histogram charts base on x/y coordinates, bar charts (vertical or horizontal), stacked bar charts, layered bar charts, OHLC financial charts (bars or candlesticks), pie charts, bubble charts, and Gantt charts.
Falcon is a simple, fast, and powerful programming language, easy to learn and to feel comfortable with. It is also a scripting engine, easily embeddable in any complex, multi-threaded and mission-critical application. Falcon provides its users with four integrated programming paradigms: procedural, object oriented, functional, and message oriented. And you don't have to master all of them; you just need to pick the paths that are ingredients you prefer, and let the code to follow your inspiration.
terp is a modular template engine that integrates tightly into ANT and provides a portable C++ compiler task (aCC, g++, icc, msvc++, SUN CC, xlC) on many platforms and processor architectures, a collection iterator task, a full-featured expression language with host introspection, formatters, selectors, and transformers for expressions, and much more. It can be embedded into Ant, used as a stand-alone or embedded templating engine, or used as a batch or interactive expression evaluator. It is extremely flexible and can be extended with your own types, operators can be overloaded, and properties and methods can be added to types.
wxAdvTable is a advanced table component designed with flexibility in mind, with clean MCV (Model-Controller-View) design. It has many advanced features like composite rows/columns, built-in sorting support, flexible rendering and editing support, dynamic row/columns add/removal, rows/columns highlight, and many visual features.
libcfp analyzes and parses the syntax of a user-supplied chemical formula in ASCII notation. It does not know anything about the semantics of real world physical element characteristics. But it requires no external library dependencies and uses namespace std:: only. Furthermore, it uses UnitTest++ during development to ensure consistent behavior of formula parsing.
