OfficeFloor provides true inversion of control for building simple static to complex real-time Web applications that are "build once, run anywhere" - even with cloud computing. It allows you to wire together a working prototype in minutes, extend the prototype to a working Web site in hours, and deploy and run anywhere. The code is self documenting to make support easier. It aims to be "The Java Web Answer" for rapid application development for Web applications.
ClodHopper is a Java library for high-performance clustering of numerical data. It contains clustering implementations such as K-Means, K-Means++, X-Means, G-Means, Fuzzy C-Means, Jarvis-Patrick, and various forms of hierarchical clustering. ClodHopper's clustering implementations take advantage of the host system's concurrent processing ability to speed clustering. The data structures are also very lean to conserve memory usage. ClodHopper is very extensible. If you are developing a new clustering algorithm, you may save yourself an enormous amount of work by extending a ClodHopper base class.
