Installing NWChem in on 64-bit Linux Cluster (CentOS, OpenMPI, Infiniband)

NWChem is a suite of computational chemistry tools that are scalable both in their ability to treat large scientific computational chemistry problems efficiently, and in their use of available parallel computing resources from high-performance parallel supercomputers to conventional workstation clusters.

Google Talk Plugin on Slackware 14

Officially Google Hangouts doesn't support Slackware Linux, limiting support to "Ubuntu and other Debian based Linux distributions". Realistically, what one is after is the Google Video and Talk plugin, but this also isn't strictly available for Slackware. Of course Google, being a little more evil that they think they are, does not release the source code for this enviable technology. What is a poor Slacker to do?

From the Linux Australia Debate: The Experience of Women in Information Technology

On Sunday, October 27th 2013 a post was made on the Linux Australia mailing list concerning an offer the GNOME Foundation in association with several FOSS provided for a three-month internship for women, specifically "to get more women involved in FOSS". On Tuesday, a poster (perhaps inspired by Sunday's post) argued against "special programmes to address an imbalance between the sexes", suggesting that such programmes are harmful, that merit "shines through inner strength", and that sex-specific programmes should be replaced with programmes for "'incompetent women in IT,' or at least to widen eligibility to include hamsters and fish."

There was, unsurprisingly, a small storm of discussion that resulted which can be mostly be broken up into two perspectives. The first were those who agreed, more or less, with the original poster with the suggestion that any gender disparity in IT may actually simply be "just how it is", that employers are almost always gender-neutral, and that any gender-specific programmes should be abolished. The second group agreed that employment should be gender neutral, but in wasn't, and there were a variety of causes (conscious and unconscious discrimination) for the disparity that justified the existence of such programmes.

Matlab R2012b DCS Job Submission

MATLAB (registered trademark implied in this post) is a popular closed-source graphical product for matrix mathematics. Whilst I certainly prefer in most cases the extremely compatible open-source competitor Octave for all the well-founded usual reasons, MATLAB does have a small mountain of libraries and a small fortune backing it, both of which aren't quite always available to the GNU Octave people. So in some cases, based invariably on user requests, some dealings with MATLAB is sometimes required.

Antireligious Prejudice in The Free Software Movement

Recently I had the experience of encountering antireligious bigotry by a free software advocate. I will not mention the person by name, but I will describe their attitudes and the effects, and by the way of elaboration on why all forms of prejudiced discrimination is not just morally wrong, but damaging to free software as a movement. The experience occurred just prior to Software Freedom Day among the organising committee.

Dear Mr. Carl,

The following is the submission by Linux Users Victoria, Inc., on the Options Paper for the Review of the Innovation Patent System.

Bleeding Edge Libraries For R

Previous posts have described the installation of R, and even installing some of its less than simple packages. But what do you do when a library appears to be installed by one of the normal methods and declares itself as such - until it is actually requested? In other words, a false positive, one of the most frightening creatures known in the world (although fortunately in this case trivial in damage).

Fire Dynamics Simulator Linux Cluster Installation

Fire Dynamics Simulator (FDS) is a computational fluid dynamics model of fire-driven fluid flow. The software solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires. It is also slightly unpleasant to install, but the following notes should make it somewhat easier.
