an Open Source Probabilistic Information Retrieval library, a highly adaptable toolkit to allow developers to easily add advanced indexing and search facilities to their own applications.
a modern alternative to object middleware such as CORBA™ or COM/DCOM/COM+. Ice is easy to learn, yet provides a powerful network infrastructure for demanding technical applications.
a way of representing structural information as diagrams of abstract graphs and networks. Automatic graph drawing has many important applications in software engineering, database and web design, networking, and in visual interfaces for many other domains
open source high performance realtime 3D engine written and usable in C++ and also available for .NET languages. It is completely cross-platform, using D3D, OpenGL and its own software renderer.
an interface for array-oriented data access and a library that provides an implementation of the interface. The netCDF library also defines a machine-independent format for representing scientific data.
a robust, somewhat scalable, cross-platform client-server messaging system for dynamic distributed applications that runs under any POSIX-compliant operating system.
a Java-like library that acts as a bridge between the C++ and the Java worlds. It offers a wide range of the Java facilities without losing the power of C++.
a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code.
allows you to call directly into native functions using natural Java method invocation. The Java call looks just like it does in native code. Most calls require no special handling or configuration; no boilerplate or generated code is required.
