Dilbert's "Salary Theorem" states that "Engineers and scientists can never earn as much as business executives and sales people."
This theorem can now be supported by a mathematical equation based on the following two postulates:
Postulate 1: Knowledge is Power.
Postulate 2: Time is money.
As every engineer knows: Power = Work / Time
Since Knowledge = Power and Time = Money, therefore Knowledge = Work / Money
Solving this equation for Money, we get: Money = Work / Knowledge

"FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).", so says the website. FFTW stands for "Fastest Fourier Transform in the West." *sigh*

Dreamwidth is an alternative to Livejournal that uses much of the same code-base. However they is certain additional features that make this a more worthwhile product to develop even if it currently is in a beta-stage.

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.

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).

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.

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.
