My actual name is Dyonisius Visser, but people have called me Dick forever. I am 48 years old and live in Amsterdam. Having been a UNIX system and network engineer for 15 years at TERENA, I recently became a Trust & Identity Service Operations manager at GÉANT (a merger between TERENA and DANTE). I use open source solutions wherever possible.
From September 2007 I was a student at the Master System & Network Engineering of the University of Amsterdam; I graduated in June 2009.
This weblog is a collection of mostly technical articles that I find worth putting online. On my GEANT wiki page and are a few interesting articles as well.
Every now and then I write articles about personal, social or economic issues.
