Boost.Join is an asynchronous, message based C++ concurrency library based on join calculus. It is applicable both to multi-threaded applications and to the orchestration of asynchronous, event-based applications. It follows Comega's design and implementation and builds with Boost facilities. It provides a high level concurrency API with asynchronous methods, synchronous methods, and chords which are "join-patterns" defining the synchronization, asynchrony, and concurrency.
Neural Network Framework is a C++ framework to develop, simulate, and analyze arbitrary complex neural networks. The programmer can use the classes provided to create neural networks with arbitrary topology and mixed type of neurons. It's very easy to add customized neurons and layers.
The Standard Portable Library (SPL) is a smart pointer based, cross platform application framework. It is intended to be used instead of STL, and has an API that should be familiar to .NET and Java programmers. It includes basic types such as Date and DateTime, runtime pointer debugging, collection templates, file I/O, networking, database access, threading, and XML parsing.
NUS (Nemesis Utilities System) is a cross-platform C++ application development framework that focuses on the development of network applications, non-GUI applications, CGI scripts, database applications, and any kind of application that needs interoperability. NUS is very modular, making it easy to maintain, debug, and deploy. The library was greatly inspired by other libraries such as Trolltech's Qt.
Akelos is an MVC framework for PHP that tries to bring the magic of Ruby on Rails to the PHP world. Akelos based applications can run on most shared hosting service providers since Akelos only requires a standard PHP installation on the server. Akelos is designed to make developers lives simpler by solving complex problems with unusual speed and productivity. Favoring "convention over configuration" leads to the creation of uniform and simpler-to-understand code.
Faith is a cross-platform C++ graphical application toolkit. It runs natively on Linux/Unix (Xlib) and Windows. It has an API strongly inspired by Qt's and has many features that are expected from a modern toolkit, including a variety of common "widgets", an aesthetically pleasing appearance, and the many critical non-portable components such as anti-aliasing and sockets.
Firebolt is a network protocol oriented library. It's not another socket library; it offers higher level services to the developer. You can structure your protocol in the form of states and the transitions between those states with the use of your custom events. Thus you no longer need to worry about what data you just received from a socket and whether or not those data are expected in the current state of your network code, since that sort of validation is all performed by Firebolt.
