Welcome!
I’m Koen and I live in Bruges (Belgium), a splendid medieval city also known as the Venice of the North.
I’m involved with computer security and I work as a member of a CERT (Computer Emergency Response Team).
I deliver services (cudeso.be) as a web-application developer (Drupal, WordPress, Joomla and plain PHP applications) and as a system administrator (OpenBSD and Linux mostly).

This site hosts a blog and I have a photo collection at Flickr.
I also have a site with some (old) Linux information.

The iPhone is such a nice piece of gadgetry but it would not be nothing without the numerous apps. I’ve been using an iPhone (iOS 3, 4 and 5) for more that a year and a half and these are the apps (*) I can’t live without.(*) only apps that are not part of the [...]
