I started developing programs when he was 12 years old and still likes to code to this day. Since 1997, I’ve been working almost exclusively with Java, doing desktop and enterprise applications for local, national and international companies alike. I love working with computers. I graduated from Monterrey Institute of Technology and Higher Education (ITESM) with a major in Physics and a minor in Electronics.

Gmail oopses

So, if you use Gmail, I’m sure you’re also getting the regular ‘Oops’ message: I’ve been having this error on and off for at least 3 weeks, and sometimes it annoys me (OK, every time). Doing a basic research, it appears many people are aware of this error, but no one knows why. Even though […]

Switched Linux Distribution… Again

After playing with Ubuntu for a while, I decided it was time to test another Linux distribution. This time, I went with OpenSuSE 10.0. As always, installation wasn’t a problem. In less than 25 minutes I had my system up and running. I liked the fact that opensuse, after installing, takes you directly to the […]

Configuring a kernel for a laptop

I’m testing Fedora Core 4 on my laptop. Basically installing it, playing around with GNOME and KDE, and the different applications that it has. I have already burnt a DVD+R (another copy of FC4 for a friend) without a problem with K3b (K3b rules! ). Eclipse comes on the installation DVD, and I installed it, […]

Accessing a Spring bean from a servlet

I’m using Ajaxtags to implement an ajax-enabled form with dynamic dropdown fields. In order to access my DAO object (which is a Spring managed bean)  to get the dropdown options, I had to have access to the Application context from a regular Servlet. The solution is very simple, but since I had some troubles finding […]

Best Linux distribution for java

I’ve been using Gentoo on my laptop for a while, and while I find the features of Gentoo to be very powerful (compile from source to target your specific machine, central source repository, repository synchronization, etc), the fact that updating any major application takes a couple of days has really hit me. I’ve been looking […]
