About me
My actual name is Dyonisius Visser, but people have called me Dick forever. I am 38 years old and live in Amsterdam; apart from my daytime job as a UNIX system and network engineer at TERENA, I run a company that does system and network consultancy in the greater Amsterdam area. I use open source solutions as much as possible, and try to keep solutions as simple as possible.
From September 2007 I was a student at the Master System & Network Engineering of the University of Amsterdam; I graduated in June 2009, but my educational weblog is still there.
This weblog is a collection of mostly technical articles that I find worth putting online, because the problems dealt with were non-trivial to solve, so other people can benefit from the information too.
On my TERENA wiki page and are a few interesting articles as well.
Every now and then I write articles about personal, social or economic issues. Most articles are English, except those that relate to a local issue in the Netherlands, which are written in Dutch.
My personal picture gallery can be found at dyonisiusvisser.nl.

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

Thanks In Advanc

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!
Hello,
Can you please provide the guidance related to “PHP Email address validation with Verify”, as i have get the error like “None of the mailservers listed for gmail.com could be contacted”
Kindly reply
Great job, on a great site, thanks for all your info (I’ve read a lot of it), I’m so glad that you put so much effort into it. Thank you so much!
Ga zo door kerel, echt super!
Dick helped me really good with the transfer of my contacts from my Nokia N95 to my new Samsung Galaxy S2. It took me hours with no succes and Dick fixed it in a couple of minutes!
