Replicating Packages on a new Debian/Ubuntu install

For a variety of reasons, you may wish to upgrade your Debian/Ubuntu or similar system without going through the normal process of a distribution update. Perhaps you are, for example, moving to entirely new hardware. Obviously you want to keep the data in your home directory; but you may also wish to keep the various packages you have previously downloaded. The following is some simple steps to make your life easier.

Gambit and FlexLM Issues on Ubuntu 8.10

A user visited with what at first appeared to be a minor problem. Previously we had installed Fluent CFD on their Macintosh system running Ubuntu but they particularly wanted to run Gambit as well, which does primarily the design modelling and meshing transition. Licenses had been received and from this point on it would seem to be a fairly trivial task.

Dilbert's Salary Theorem and Engineering

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

Installating FFTW on 64-bit AMD Opteron Cluster CentOS 5 Linux

"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*

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

CPMD, Car-Parrinello Molecular Dynamics, is an ab initio Electronic Structure and Molecular Dynamics Program and is copyrighted jointly by IBM Corp and by Max Planck Institute, Stuttgart, but distributed free of charge (with source) to non-profit organizations.

Installing Dreamwidth on a Ubuntu Server

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.

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

EMBOSS is "The European Molecular Biology Open Software Suite", a free and open source analysis package specially developed for the molecular biology community, by allowing the retrieval of sequence data in a variety of formats as well as providing extensive libraries.

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.
