About me

Dick's picaMy actual name is Dyonisius Visser, but people have called me Dick forever. I am 45 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.

  5. Hi Dick,

    i’ve got a problem on your email smtp validation.

    it won’t work when i put it on my website via ftp.

    but it works in your demo.

    can you give me some help or advice or a copy of the demo on your site (which works)

    Thanks In Advanc

  6. Sir,

    You are a hero. Having spent days and days trying to backup the Contacts (all 384 of them) from my Nokia 6500 Classic, I found your website that converts the Nokia PC suite .nbu file into a zipped set of .vcf files. 2 seconds later, problem solved. If only Nokia would pay you something for fixing their rubbish code, the world would be just. Thanks a million!
