Welcome.
I'm Koen and I live in Bruges (Brugge) (Belgium), a splendid medieval city also known as the Venice of the North
I work as a member of a CERT (Computer Emergency Response Team). I'm also available as a web-application developer (PHP) and as a system administrator (OpenBSD and Linux mostly).
My main interests in computers are security, web applications (PHP) and free software.
This site hosts a blog and a photo collection (moved to Flickr). I have an account at VirtualTourist and I'm a CouchSurfer.
I also have a site with some (old) Linux information
