The Joker

Hi, my name is Jan Verhoeven. I set up this site because of my many interests. Perhaps some people out there may be interested in a few of the topics I researched or in completing one of my many orphaned projects. Starting is more interesting than finishing when you have a creative mind.

When browsing this site, please keep a constant eye on the 'LINKS' or 'Navigator' frame on the right. It is context sensitive and makes browsing this site a snap.

Also bear in mind that (in principle) me and my family run our lives with as little microsoft products as possible. Our daughter, which is in secondary school) sometimes requires the use of the Internet Exploder when visiting the school's website. It sometimes looks like microsoft is the biggest sponsor of dutch educational system.
If interested, take a look in the Philosophy file. You will find an explanation there why I have a picture of The Joker in this place....

Let's not blow things out of proportion..

About Fruttenboel.

What's this about 'Fruttenboel'? What does this typical maximum-security-level Unix-password mean? Well, let me explain. It's part of the local vocabulary. The word is only known in a small area in the south of The Netherlands. Around Tilburg to be precise.

The word WAS intended to function as a kind of password, but then, all in a sudden, it was the name of the subdomain at Geocities... And then I kept it. And now I don't want to change it anymore.
Fruttenboel is an expression when people here reach a dead-end and don't know how to commence (at that time) so they say something like: "You know what it is? It's a big 'fruttenboel'. And that's what it is!" So a 'Fruttenboel' is a kind of messy and seemingly chaotic situation. But a situation that CAN be mastered, in the end. So the best example of a true fruttenboel, is the present internet... Isn't it?
