OpenCV Linux Cluster Installation

OpenCV (Open source Computer Vision) is a library of algorithms and code for computer vision with extensive documentation and books.

Disabling Javascript; A snopes.com Inspiration

Snopes.com, the "Urban Legends Reference Pages" is an excellent site for debunking said material. Email chain-letters particularly annoy me because people simply don't do any verification testing at all; a particularly bigoted and false email circulated prior to the last Australian census is one which particularly annoyed me. Although I was even more annoyed when one person showed complete indifference to the facts and continued circulating said email. Almost made me want to become an imam out of spite towards the vile bigot.

Installing OpenFOAM : A Detailed Guide

Installation of OpenFOAM (and Paraview) can be carried out through several different methods, depending on the user's desires and the Linux distribution and package manager that is being used. Essentially there are three main methods; either installating with the Advanced Packaging Tool (apt) common on Debian, Ubuntu, Mint, etc., with various front-end implementations (e.g., aptitude, Synaptic, Ubuntu Software Center), the Red Hat Package Manager (rpm), common on SuSE, RHEL, Fedora, CentOS, Mageia, etc., with its front-ends (e.g., yum, up2date, urmpi), and compiling from source.

Schrödinger, Maestro and Remote Connections

The installation of the chemical simulation suite, Schrödinger on high performance computer systems is hardly unusual. What is problematic is when users wish to access the GUI package, maestro, remotely using x-windows forwarding. Except when a user is extremely close to the system it is extremely likely that the graphic representation will be frustratingly slow for manipulation. There is, however, some ways around this.

JAGS (Just Another Gibbs Sampler) Installation.

For those fascinated by the world of analysis of Bayesian hierarchical models using Markov Chain Monte Carlo (MCMC) simulation (and let's face it, who isn't?), there is a delightful program called JAGS. Unfortunately it is a little stubborn to install.

Download the latest version from our friends at Sourceforge and extract in a sensible place (e.g., /usr/local/src/JAGS.

Now witness some example failures to install, which a reasonable person would assume would be sufficient.

Rmpi and INLA: A couple of different R packages

Some R libraries and packages are easier to install than others. The typical method is to download the tarball and run R CMD INSTALL -l /path/to/library pkg1 pkg2 from the Linux command line or install.packages(c("pkg1", "pkg2")) from the R command-line after selecting from chooseCRANmirror(). But not every R package follows this contention.

The Worst of English

Presentation to the Unitarian School of Languages, Friday December 14, 2012

1. Phonemic representation

Can "ghoti" be pronounced "fish"?

gh is pronounced "f", like "enough".
o is pronounced "i", like "women".
ti is pronounced "sh", like "nation".

The first published reference is in 1874, citing an 1855 letter that credits ghoti to one William Ollier Jr.

Replace Latin Swedish with Unicode in PhpMyAdmin

When establishing a website database (e.g., Drupal, Wordpress etc) with PhpMyAdmin (e.g., through CPanel) one may be surprised to discover that the default character collation order is in latin1_swedish_ci. For most "plain text" ASCII-style posts this isn't a problem. It becomes a problem however when an article is supposed to display characters which require a different character set. A personal discovery of this nature was with Esperanto diacritical characters. Characters which latin1_swedish_ci cannot display will be replaced with "?", one per character.

The Story of Mel, A Real Programmer

This was posted to USENET by its author, Ed Nather (utastro!nather), on May 21, 1983.

A recent article devoted to the *macho* side of programming made the bald and unvarnished statement:

GAMESS Parallel Installation

The General Atomic and Molecular Electronic Structure System (GAMESS) is a general ab initio quantum chemistry package. Before installation you must agree to the license. A link will be provided from which the source can be downloaded.
