Af-Arch is an N-tier development framework to quickly build high-quality distributed applications. It currently supports C and C# programming languages, which enables you to write client applications using them. It currently runs on GNU/Linux and Microsoft Windows, and is being used in production environments.
AIMLBot (Program#) is a small, fast, standards-compliant yet easily customizable .NET DLL implementation of an AIML (Artificial Intelligence Markup Language) based chatter bot. It boasts cross-platform compatibility, a modular architecture, a simple and logical API, standards compliant AIML support with the option for extensions via custom tags, very small size (currently only 56k), and very fast performance (over 30,000 categories processed in under a second).
Aorta is a load-balancing clustered P2P application. It executes Tasklets (which have the ability to split themselves into sub tasks that can be executed in pararell). A typical cluster contains of a LAN with 1-256 computers, each one running aorta. A Tasklet can be of any type ranging from encoding MP3s, Genomic DNA Alignment, or simply to rendering Web pages for high speed/heavily loaded Web sites. You can make functions calls to C/C++, applications like Matlab, etc.
AutoDiff.NET is a pure .NET library that allows a developer to easily compose functions symbolically and then automatically calculates the function's value and gradient at any given point. It can be very useful in conjunction with a gradients-based optimization library. It has been tested to work on Mono 2.10 on Linux and on .NET4 on Windows.
Bandit is a system of loosely-coupled components that provide consistent identity services and create a community that organizes and standardizes identity-related technologies in an open way, promoting both interoperability and collaboration. It implements open standard protocols and specifications so identity services can be constructed, accessed, and integrated from multiple identity sources. The Bandit system supports many authentication methods and provides user-centric credential management.
Bugzproxy is a C# client library for the upcoming Bugzilla Bugtracker WebService interface (part of Bugzilla 3.0). It provides an OO access to a Bugzilla server. The aim of Bugzproxy is to allow easy building of various clients that facilitate the integration of Bugzilla into the various C# tool chains. As the project's aim is to provide an efficient and intuitive OO API, the API probably will change in future revisions.
