Last sunday I upgraded my website software… phew!, It was a long task, but final result was very pleasant :-). Right now it’s running on Wordpress 1.5. Very nice. One major change was the use of subdomains instead of subdirectories. I pretend to keep all blogs cleaner by putting each one in its own subdomain space. The price is some broken links on the net ;-)…

This tree is in my garden… yummi, yummi

Two months ago I designed this logo for an internal company product contest. I didn’t win, but I learned a lot. Xara made the work very simple, and well… hope you like it as much as I do…

Three weeks ago I had to work on polyominoes for a final project. Since I had to program an enumeration quickly, I wanted to find a simple algorithm to do it. Well, my search was hard. I barely found information on enumeration algorithms and read the work of many people including Redelmeier, Knuth and Ares Ribó. I chose to go the Redelmeier way because of the short time to complete the task. Here you can find part of my work, as well as some documents that explain more on this topic.
