Started Made IT on April 1st 1997, because I felt there was too little free information available about connectivity. The documents are still available at ckp.made-it.com.

Have build my own Linux distro, in july 2000, as a showcase for GNUstep, named LastStep and terminated the project Januari 2002 due to a lack of time.

Wrote a couple of GNUstep guides

Wrote a couple of other documents available at http://documents.made-it.com

My hobby project: http://www.strandvondsten.nl

On the 24th of September 2007 the Dutch book: Probleemloos overstappen op Linux (ISBN: 978 90 12 11775 3) was published by SDU publishers. This book I wrote together with Jan Stedehouder.

I like to create stuff, which can be the writing of manuals, creating trainings or designing and structuring a network. But also trouble shooting networks or analysing data flows.

What I have always liked about computers is the interaction between them. I would like to work with systems that enable people to communicate.

I also like to work with people, listening to their needs and translating that into solutions.
