CogTool 1.0b18
CogTool - application to assist in the creation of design mockups and the calculation of predictions of skilled performance time more>>
Detailed information is provided in the CogTool User Guide. We strongly recommend that you read the guide to get the most out of the CogTool system.
To help you get started quickly with CogTool, we have also provided a Tutorial. This document walks you through an example in detail, but it is not as comprehensive as the CogTool User Guide and it refers to the CogTool User Guide, so you need both.
The installation procedure differs depending on the platform being used for modeling. The software is currently available for the Mac OS X (10.4 or higher, including IntelMacs) and Windows (Windows 98 or higher) platforms. Follow the instructions below for the appropriate platform.
The ability to execute task models integrated with driving is not available in the current version. If your primary interest is models integrated with driving, you may still use the old version, which requires a Mac OS X system (but does not run on Intel Macs).
Enhancements:
- New features in CogTool 1.0b17 include support for some new widgets, faster importing of background images from a folder, improved performance all around, new properties panes, the ability to export storyboard and scripts to various formats, a visualization of what the underlying computational cognitive engine (ACT-R) is doing to produce the human performance predictions, and re-written users guide and tutorial.

OpenBabel is a project designed to pick up where Babel left off, as a cross-platform program and library designed to interconvert between many file formats used in molecular modeling and computational chemistry.
Open Babel includes two components, a command-line utility and a C++ library.
The command-line utility is intended to be used as a replacement for the original babel program, to translate between various chemical file formats.
The C++ library includes all of the file-translation code as well as a wide variety of utilities to foster development of other open source chemistry software.

EvoJava 0.9.0
EvoJava - Software for exploring computational models of biological systems more>>
I have developed and tested EvoJava using Gentoo Linux on Opteron and Pentium systems; Ive also tested with Microsoft Internet Explorer and Firefox for Windows XP SP2 (where I have Suns Java installed.)
This is a preliminary beta version of EvoJava. It contains only four "universe" types, and lacks significant documentation. Im releasing this code "as is", hoping users will help me improve the final program. Keep an eye on these pages for updates. I make no promises about schedules or about what the final program will include; all I can say is that EvoJava is moving along nicely. The final release will include full, documented source code, released under the GPL.

Madagascar 0.9.8
Software package for geophysical data processing and reproducible numerical experiments Madagascar is an open-source software package for multidimensional data analysis and reproducible computational more>> Software package for geophysical data processing and reproducible numerical experiments
Madagascar is an open-source software package for multidimensional data analysis and reproducible computational experiments.
Madagascar aims to provide:
- a convenient and powerful environment
- a convenient technology transfer tool
for researchers working with digital image and data processing in geophysics and related fields. Technology developed using the Madagascar project management system is transferred in the form of recorded processing histories, which become "computational recipes" to be verified, exchanged, and modified by users of the system.
Main features:
- Madagascar is a modern package. Started in 2003, and publicly released in 2006 it was developed entirely from scratch. Being a relatively new package, it follows modern software engineering practices such as module encapsulation and test-driven development. A rapid development of a project of this scope (more than 300 main programs and more than 3,000 tests) would not be possible without standing on the shoulders of giants and learning from the 30 years of previous experience in open packages such as SEPlib and Seismic Unix. We have borrowed and reimplemented functionality and ideas from these other packages.
- Madagascar is a test-driven package. Test-driven development is not only an agile software programming practice but also a way of bringing scientific foundation to geophysical research that involves numerical experiments. Bringing reproducibility and peer review, the backbone of any real science, to the field of computational geophysics is the main motivation for Madagascar development. The package consists of two levels: low-level main programs (typically developed in the C programming language and working as data filters) and high-level processing flows (described with the help of the Python programming language) that combine main programs and completely document data processing histories for testing and reproducibility. Experience shows that high-level programming is easily mastered even by beginning students that have no previous programming experience.
- Madagascar is an open-source package. It is distributed under the standard GPL open-source license, which places no restriction on the usage and modification of the code. Moreover, access to modifying the source repository is not controlled by one organization but shared equally among different developers. This enables an open collaboration among different groups spread all over the world, in the true spirit of the open source movement.
- Madagascar uses a simple, flexible, and universal data format that can handle very large datasets but is not tied specifically to seismic data or data of any other particular kind. This "regularly sampled" format is borrowed from the traditional SEPlib. A universal data format allows us to share general-purpose data processing tools with scientists from other disciplines such as petroleum engineers working on large-scale reservoir simulations.
System requirements:
-
Enhancements
- New reproducible papers, several structural changes, and numerous bug fixes.

Folding@home Screensaver 5.02
Folding@home Screensaver - distributed application screensaver more>>
What is protein folding and how is folding linked to disease? Proteins are biologys workhorses -- its "nanomachines." Before proteins can carry out these important functions, they assemble themselves, or "fold." The process of protein folding, while critical and fundamental to virtually all of biology, in many ways remains a mystery.
Moreover, when proteins do not fold correctly (i.e. "misfold"), there can be serious consequences, including many well known diseases, such as Alzheimers, Mad Cow (BSE), CJD, ALS, Huntingtons, Parkinsons disease, and many Cancers and cancer-related syndromes.
You can help by simply running a piece of software. Folding@Home is a distributed computing project -- people from through out the world download and run software to band together to make one of the largest supercomputers in the world. Every computer makes the project closer to our goals.
Folding@Home uses novel computational methods coupled to distributed computing, to simulate problems thousands to millions of times more challenging than previously achieved.
