- Final exams in Dutch, English,
Mathematics I and II, Physics, Chemistry, Biology.
- 1984-1990,
Computer Science at the
Radboud University

Physics as minor. Master degree project was named "Real-Time Fault
Tolerance in Multi-Controller Systems".

My primar field of interest is unusual complex programming problems
and internet developments.
Experience
The fundaments of my computer related activities were laid at
De Jonge Onderzoekers (Young Scientists),
where I came in touch with their self-made computer in 1978. I learned to
program BASIC and assembly, and then designed a few computers myself.
During my study Computing Science
(Informatics) at the Radboud University, I was most attracted by
the technical subjects. And only when I had taken all the classes
they had to offer, my time had come to finish. My Master Thesis, entitled
Fault Tolerance in Real-Time Multi-Controller Systems, implemented
a system with many computers which continuously check and correct another.
An example of such a system can be found in the Space Shuttle.
Complex systems fascinate me.
After my degree, I came to work for the Dutch National Aerospace
Laboratories NLR. Located below sea-level
in a Dutch polder, the NLR is mainly occupied with research and development
in the airplanes, airport control, and satellites. To support this work, it has
a very modern computing center. On the moment I started working at the
NLR, they just had bought their second UNIX computer. When I left, they
had 130 from 20 different brands.
My task at the Computing Center was to organize the centralized
backup and user registration. Therefore, I wrote enormous amounts of
C and shell scripts. Besides, I participated in a few large scale
software projects.
During my stay at the NLR, the World Wide Web emerged.
The NLR was one of the first places where WWW got implemented. As hobby
project, I helped with the development of The Dutch Home Page,
the tenth website (in order of appearance) in the Netherlands. On this
very moment, I have more than twelve websites. Regularly, new site are
added to that list.
After six years at the NLR, I wanted to learn more. By joining the
renowned UNIX training company
AT Computing I could
dedicate my time on UNIX system administration, website development, and
Perl and C programming. In total, I gave about ten different courses,
of which I had developed three.
At AT Computing, I came in touch with Perl. It became my preferred
language in the last five years: it is the fastest language to implement
all my ideas. Sometimes, I use C or Java to support Perl. On this moment,
I maintain five Open Source Perl modules of my own hand. They are available
from CPAN, the central Perl software archive.
Most of these modules are e-mail related.
In short:
- experienced administrator for many UNIX brands, but recently mainly Linux;
- experienced programmer (in total 30 languages used), recently mostly
Perl and C, some Java; and
- experienced website developer, both the technical as the user interfacing
aspect.
Papers and Presentations
When I visit a conference, I tend to give a presentation.
My main subjects are Internet and Perl. An overview of my conference
appearences follows. Visits to conferences (like OSCON) without a talk
are left out.
The numbers represent the number of short
presentations (usually 30 or 45 minutes) and tutorials (usually 3 hours)
that I presented at the event.

Natural languages

and writing go with ease. German is on conversational level, so needs
a little more effort.
