About me

My name is Rudy Velthuis. I was born in 1960, in Eindhoven, the Netherlands, and studied Dentistry in Nijmegen. In 1985, I moved to Germany, and I have lived here ever since. For my living, I work as a dentist. Since 1987, I have my own clinic in Gladbeck, Germany — since the end of 2006 even a new, bigger one. I am married, and we have one son.

I am an enthusiastic hobby programmer, and for this, I prefer Delphi. I have been using Borland products since 1985, mostly Turbo/Borland Pascal and Delphi, but also C++Builder, Kylix and C#Builder.

I have done some simple things in other programming languages as well, most of them in BBC-BASIC, BCPL, FORTH (before 1985), Assembler (6502, Z80, x86), C and C++. My first "big" project was writing a complete disk operating system for my Acorn BBC B home computer, completely in assembler (16k ROM).

My other computer interests are designing icons and other little pictograms, and sometimes working with the POV-Ray raytracer (http://www.povray.org).
