An example why open source software is cool
Recently I have set up an Apache Tomcat. As a replacement for the Tomcat manager I deployed Psi-Probe for easy deployment and access to statistics.

Ubuntu 10.04 LTS released

This time, Ubuntu radically changed its look. From my point of view it looks ugly, very ugly. Strange colors, low contrasts in menus, orange icons in Nautilus… ….Read More
