Ruby-UDBM is a Ruby binding for the UPPAAL DBM library. It offers access to the federation type (set of DBMs) and most of its operations. In addition, a graphical viewer is provided to allow users to visualize updates on the fly. The library gives access to systems of constraints where clock constraints can be declared and used as intuitive formulas. This binding is intended to be a research prototyping tool as well as a teaching tool for students learning timed automata.
MultiChat is a chat client with the major focus on one-to-many communications (chat rooms and others). It does not aim to be a multi-protocol client. Instead, it seeks to provide multiple chat and collaboration resources based on integrated development with a single protocol and server software.
HTML Include solves the problem that the Hypertext Markup Language doesn't know a command for including other files into a source file. It uses specially styled comments to refer to other files, which will be inserted at this position. Unlike to the well known Server Side Include mechanism, this tool pre-processes the HTML files, resulting in files that have all referenced source files directly embedded. Thus it does not depend on any Web-server for correct appearance. As a bonus, HTML Include also writes the current date to the "last modification" line and brower meta, which you usually forget (or do not bother) to update.
PCP (Pattern Classification Program) is a machine learning program for supervised classification of patterns. It runs in interactive and batch modes, and implements the following machine learning algorithms and methods: k-means clustering, Fisher's linear discriminant, dimension reduction using Singular Value Decomposition, Principal Component Analysis, feature subset selection, Bayes error estimation, parametric classifiers (linear and quadratic), pseudo-inverse linear discriminant, k-Nearest Neighbor method, neural networks, Support Vector Machine algorithm (SVM), model selection for SVM, cross-validation, and bagging (committee) classification.
Tao is a software package for sound synthesis using physical models. It provides a virtual acoustic material constructed from masses and springs, which can be used as the basis for building quite complex virtual musical instruments. It comes with a synthesis language for creating and playing instruments and a C++ API for those who would like to use it as an object library.
