ECharts: A state machine-based programming language

ECharts is a state machine-based programming language for event-driven systems derived from the standardized UML Statecharts language. ECharts distinguishes itself from other Statecharts dialects by focusing on implementation issues such as determinism and code re-use. Like Statecharts, ECharts supports hierarchical state machines, concurrent machines and a graphical syntax. Unlike Statecharts, ECharts supports a simple textual syntax, machine reuse, multiple transition priority levels to minimize non-determinism, machine arrays, and a new approach to inter- and intra- machine communication. ECharts is a hosted language which means that it is dependent on an underlying programming language such as Java. ECharts has a proven track-record in a large-scale commercial deployment.

GGobi: Data visualization for high-dimensional data

GGobi is an open source visualization program for exploring high-dimensional data. It provides highly dynamic and interactive graphics such as tours, as well as familiar graphics such as the scatterplot, barchart and parallel coordinates plots. Plots are interactive and linked with brushing and identification.

GSDjVu/DjVuDigital: Ghostscript driver to convert PS and PDF files to DjVu files

gsdjvu contains the source code for a Ghostscript driver that enables to convert PostScript(tm) and Portable Document Format (PDF) electronic document files into DjVu files.

Graphviz: Tools for viewing and interacting with graph diagrams

Graph visualization is 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. Graphviz is open source graph visualization software. It has several main graph layout programs.

PADS: Processing Arbitrary Data Streams

PADS is a system that simplifies processing ad hoc data sources. Its users can declaratively describe data sources and then use generated tools to understand, parse, translate, and format data.

Sfio: Portable library for performing I/O

UWIN: Unix on Windows 95 and NT Machines

Vcodex: Software package for data transformation

WSP: Web Scraping Proxy

Programmers often need to use information on Web pages as input to other programs. This is done by Web Scraping, writing a program to simulate a person viewing a Web site with a browser. It is often hard to write these programs because it is difficult to determine the Web requests necessary to do the simulation. The Web Scraping Proxy (WSP) solves this problem by monitoring the flow of information between the browser and the Web site and emitting Perl code fragments that can be used to write the Web Scraping program. A developer would use the WSP by browsing the site once with a browser that accesses the WSP as a proxy server. He then uses the emitted code as a template to build a Perl program that accesses the site.

Yoix: The Yoix Scripting Language and Interpreter

The Yoix scripting language is a general-purpose programming language that uses syntax and functions familiar to users of C and Java. It is not an object oriented language, but makes use of over 150 object types that provide access to most of the standard Java classes.

iPlots: Interactive graphics for data analysis in R

iPlots is a package for the R statistical environment which provides high interaction statistical graphics, written in Java. It offers a wide variety of plots, including histograms, barcharts, scatterplots, boxplots, fluctuation diagrams, parallel coordinates plots and spineplots. All plots support interactive features, such as querying, linked highlighting, color brushing, and interactive changing of parameters.

vmalloc: Region Memory Allocator

Non-Commercial Binary Licenses

BoosTexter: A general purpose machine-learning program

BoosTexter is a general purpose machine-learning program based on boosting for building a classifier from text and/or attribute-value data.

Hancock: A language for processing large-scale data

Hancock is a C-based domain-specific language designed to make it easy to read, write, and maintain programs that manipulate large amounts of relatively uniform data. Because Hancock is embedded in C, it inherits all the functionality of C. Valid C programs are also valid Hancock programs, and Hancock programs can use libraries written for C. But Hancock is more than C. In addition to C constructs, Hancock provides domain-specific forms to facilitate large-scale data processing.
