Load balancing and high availability

One of the benefits of working with people smarter than you is the chance to never stop learning. My office mate, Bernie Ács, is an extraordinary source of experience and wisdom on production systems. Just right after coming back from vacation, he started unfolding a virtualized solution for high availability and load balancing of services. It is not me the one who should disclose the solution, but I just want to mention a piece of the puzzle that I found very interesting: ldirectord. In the words of the ldirectord developers: ...

Penrose, conciousness, and delayed homework

Long time delayed, I finally got a copy of The Emperor’s New Mind by Roger Penrose. The book was originally published in 1989. Yes, I never read it from cover to back, and finally yesterday I run out of self imposed excuses and got me a copy. I guess that it was the result of listening to the Teaching Company lecture series The Phylosophy of Mind by John Searl, also falling on the same alley. Recreative reading, may be, but I am still fascinated to keep running into belivers and detractors of strong and soft AI almost 20 years after Penrose’s book was published. ...

A simple skeleton plugin for Wordpress

Preparing for the upcoming Meandre release, as part of the larger SEASR on, I have been exploring a bit the inner machinery of WordPress to create a simple plugin for the SEASR site that could render Meandre component and flow descriptions straight out of their RDF desciptors. Actually, it turned out to be a breeze. After being a heavy user of WordPress in several project for few years now, its extensibility keeps sparking new possibilities in my mind every time I look into any of its facets. Anyway, I am rambling. Back to the point. To hit the ground running, I started by creating a simple generic plugin that would replace a tag with parameters for something else. I looked into several freely available plugins, the one that got me going was a very simple one, the SlideShare plugin by Joost de Valk. ...
