Comparison between TWiki, MediaWiki and Confluence

Executive Summary

Different Wikis are suitable for different things. TWiki has the best features, but really needs some crafting in terms of appearance. MediaWiki is easily to deploy, is attractive, but is not structured. If you need a structured Wiki with workspaces you'll might want Confluence. If you want community development in an unstructured manner, you want MediaWiki. If you want separate webs, structure, but also community development, go for TWiki - and then reskin it.

Installing Ultrascan on a 64-bit AMD Opteron Cluster running CentOS 5 Linux

UltraScan "attempts to be a comprehensive data analysis tool for the hydrodynamic studies of macromolecules and macromolecular assemblies with analytical ultracentrifugation experiments."

Sounds like fun. Let's install it. Get the tarball, ignore the part of the site which uses frames and extract in a sensible place, such as /usr/local/src/ULTRASCAN (tar xvf ultrascan-9.9-888-qt-3.3.8-ix86-linux.tar.gz).

Installing OpenFOAM 1.5 on a 64-bit AMD Opteron Cluster running CentOS 5 Linux

OpenFOAM (Open Field Operationa and Manipulation) is a computational fluid dynamics toolbox which simulates "anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics, electromagnetics and the pricing of financial options." All this and free and open source as well.
