QtWebApp allows you to write standalone Web server applications in C++ as easily as Java Servlets. The HTTP 1.1 server supports persistent connections, sessions with cookies, and file uploads. It contains a template engine and a logger that can be configured at runtime. The application runs on Unix as a daemon, on Windows as a service, and on all operating systems on the command line. It is based on Nokia QT 4.7. Compatibility with QT 4.8 and 5.0 has been verified successfully.
ArtTk is a graphic library based on Java/Swing offering an open development toolkit intended specifically for scientific and technical applications. It provides a set of widgets and functional modules a set of support modules (helpers) permitting dynamic definition of menus and tool bars from simple XML configured files, and supporting tooltips, icons, action commands, etc.; a very adaptable generic desktop, facilitating the assembly of Swing components in a specialized GUI; an extended Grid layout to simplify the development of advanced scientific applications; and a set of scientific and technical widgets, such as a dynamic memory footprint monitor, simple key-values based fields editors, a generic color gradient editor, etc.
usb4java is a Java library for accessing USB devices. The low-level part is based on the native libusb 0.1 shared library and reflects this API as completely as possible. Java NIO buffers are used for data exchange between libusb and Java. The high-level part implements the javax.usb standard (JSR-80). Supported platforms are Linux (x86 32/64 bit), Mac OS X (x86 32/64 bit, PowerPC 32 bit) and Windows (x86 32/64 bit), but other platforms supported by Java 6 and libusb may work by compiling the JNI library manually.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
Athena Framework for Java is a full fledged enterprise object-relational mapping (ORM) framework that employs metadata as mapping configuration. It greatly simplifies Java Web application development by removing the requirement of manual mapping and manual database schema updating. In addition to features like Java object persistence, powerful EJBQL querying execution, and comprehensive code generation, Athena has built-in support for multi-tenancy, which enables developers to build cloud applications easily. Athena can be easily integrated with other libraries like Struts or Spring to provide full stacks of service.
Dr. Geo is an interactive geometry program that is distributed as a universal portable application. It allows one to create a geometric sketch and manipulate it according to its constraints. It is usable at home or at school, in primary or secondary education. It is simple and effective with extended features including scripting and programming.
LampCMS is a Q&A Web site with best features of StackOverflow and Quora mashed together. It integrates with Twitter, Facebook, Tumblr, and the Blogger API, and can post questions and answers to all of these APIs. It is very fast and can handle millions of monthly visitors on a single inexpensive server.
EO is a template-based, ANSI-C++ evolutionary computation library that helps you to write your own stochastic optimization algorithms quickly. Evolutionary algorithms form a family of algorithms inspired by the theory of evolution, and solve various problems. They evolve a set of solutions to a given problem in order to produce the best results. These are stochastic algorithms because they iteratively use random processes. The vast majority of these methods are used to solve optimization problems, and may be also called "metaheuristics". They are also ranked among computational intelligence methods, a domain close to artificial intelligence. With the help of EO, you can easily design evolutionary algorithms that will find solutions to virtually all kind of hard optimization problems, from continuous to combinatorial ones.
