| Websites that I've work on
The last few years I've made several websites or parts of websites. Some were for personal
use, others were commercial sites or homepages of friends. At SRON I've made big parts of
the Intranet and also some parts of the SRON WWW site. Since some of the best stuff is only
visible within private networks I've made screendumps or copies of these parts to give
you an impression. You may catch an idea for yourself.
Almost all websites where I still do site maintenance are now HTML 4.01
compliant. They have been validated by the HTML and CCS validator at
www.w3.org. Only a few pages still contain
non-compliant HTML tags, the most obvious one is the definition of Framesets without a
border. Also style sheets are fully compliant with CCS standards of the World Wide Web
Consortium (W3C). This means that all pages should render properly on all browers that
follow these standards. Most of the pages have been tested with MS Internet Explorer 4.x
and 5.x, Netscape Navigator 4.x, Mozilla and Lynx.
SRON WWW site
Together with Chiel Galama the new look of the SRON site
was made in 1998. The navigation part and the graphical work was my idea. Chiel did most
of the underlying directory structure and updating the first set of pages. When this work
was done, the responsebility was turned over to the divisions.
In 2000 they completely changed the design, so my work cannot be seen there anymore.
SRON-Info - the Intranet
Since 1997 I've been working on the Intranet. It started as a small testcase to see if the
idea's people had could be turned into a working project. When SRON was confident enough
it was turned into a real project and they offered me this job. For more then 1.5 years
I've build several modules. Most of the pages in the Intranet are software generated.
Coupling scripts with an underlying database is used for the address module, an invoice
system and many other modules.
Work was done here as well on the server side. Upgrading the webserver in order to make
use of File-uploads, security policies (running the outside and inside system on one server)
and Publishing directly from within the browser (Netscape Gold version).
Also for this project the graphics were all made by me. Using tools like Paint Shop Pro and
Photopaint for the standard bitmaps and a special toolkit to make text in a button directly

shopping cart. The whole site is generated out of a database to make life easier when
prices and products change.
Star Trek fortune cookie generator
This is not really a complete website, but more a lesson for how to make use of smart software
to randomly generate pages without much effort. Although I did not post it anywhere, several
people found it (from all over the world). Every time you enter the page a new picture
from the old Star Trek series is shown plus a random
Star Trek Fortune Cookie.
For a few years a group of four people from the CCD group had a competition. Guessing the
scores from our national soccer competition. When three of the four left Utrecht we had a
communication problem. But since a had a lot of expierience with this sort of infrastructure
problems I made a complete Toto Website
for all the competitors. Even the site maintenance is done from the browser. Again using a
database and scripts this site has been woring since 1998. Since it is free to use by
everybody, we encourage other people to join in. Recently I have ported the software from
a HP workstation with an Oracle database to Linux with PostgreSQL.
Combining a webdesign from my collegues at Groningen with my own design of a document system
that was web-enable resulted in this website. The HIFI project is the new mega project where
SRON is the Principle Investigator. More then 20 institutes are working together to build
instruments for a new satellite. People can exchange documents and links them to meetings.
After running very well for two years the person who became responsible for the
maintenance of this site didn't know a damn thing about HTML and scripting so he
decided to build a new site. Complete with useless Java applets, screaming colors (if you
have a palette of 16 million colors, you might as well use them, argh....). Needless to
say that I wasn't happy to watch this improvement. Oh well, I am not working there
anymore, so I shouldn't be worrying about it. I only feel sorry for the people who have
to work with it.
Conference website about Low Temperature
Detectors organized by SRON, ESA and STW. Due to great web management also not visible
anymore. The stuff is still there, but not visible due to changes in the web infrastructure.

Homepage of Peter Roos
Peter Roos is a haptonomist and he also making sculptures. He has made quite a lot
of them in only a few years. So it was about time that he presented them
to the world. Check out his
website. While Peter delivers all
the pictures of the sculptures, I put it all together on his site. All the graphical
work is also done by me. Thanks to my brother (his name is also Peter) for making
the logo into a vector-based drawing.
Short project that didn't work out, but was still useful
I was working on a new project in my spare time in 1999, to build a website for a friend
who had a new (well, sort of anyway) way of distributing information. Yeah,
I think this sounds vague enough! I was setting up a Linux box with a webserver
and a database. Together with a modified version of Tcl I accessed the
database, just like I used to to with Oracle on other projects. But now it is
all free software (Linux, Apache, PostgreSQL and pgtcl). The idea was turned into
a live website, but it was never turned into a real business.
The underlying software library that I wrote however formed the basis of many new
web applications that I wrote so it was not time wasted. Amazing what you can do during
a weekend in a hotel in Spain.
XMM-Newton Observation Log Browser
When I worked in Spain I decided to write a database application that would be accessible
from the web to enter and retrieve information about all the observations taken by the
XMM-Newton satellite. It started as a private project to help my instrument team, but
I decided to make it generic enough for all instrument on-board. Soon the whole project
saw the advantage and it became a core tool, to be used by everybody.
Website for the Sibusiso Foundation.
This Dutch foundation is building a home for mentally handicapped children in Tanzania. A
great initiative from Atty en Henk Hammer. The website contains information about the
foundation, what they are doing, addresses, newsletters and lots of pictures about
the work being doing in Tanzania.
REC ZHZ De Nachtegaal
Website for the Regional Expertise Centre
Nachtegaal. This is a collaberation between about 20 schools for special education.
On the website you can find out what kind of education is given, addresses and
