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).

Now the fun starts

Google have announced Google Chrome OS. This is interesting on several fronts.

Firstly, and most obviously, this is an open statement of war on Microsoft. It is written in the text of the announcement "We hear a lot from our users and their message is clear — computers need to get better." This device will have no MS APIs on it. None. Nada. The end of the MS lock in.

Which Bank?

Which bank gets confused about some fairly trivial technical and security issues on their own helpdesk system?
