My name is Derk-Jan Hartman. I used to edit, but now I mostly deal with English Wikipedia tech stuff. I'm a volunteer contributor to the MediaWiki software that runs Wikipedia and to Wikimedia Mobile. A long time ago I was one of the volunteer developers of VLC media player.
Most of my time is spent answering questions of editors on the technical Village Pump, maintaining the site specific Javascript and CSS, working on templates and doing administrative work with regard to images (moving, deleting etc). I also do a lot of work with various User scripts and Gadgets. My article interests are with topics regarding space and the Netherlands. I'm an occasional author for The Signpost.
Articles that I significantly edited and brought to GA/FA
Folded references a small script that collapses refs by default and it uses show/hide.
User:TheDJ/slimpopups.js will be a new implementation of popups that will be faster and slimmer.
User:TheDJ/svg.js a script for Safari, that replaces all svg thumbnails with the actual SVG files. (bandwith hog, only for those who want to experiment).
When you wikilink these pages in a template from within a #if: optionname, then you can use their "What links here"-link, to see which pages use certain arguments of templates. /Tracker1/Tracker2/Tracker3/Tracker4

People being nice
Some people are really nice and have seen it fit to award me a barnstar. If vandals are one side of the Wikipedia spectrum, these people are surely at the complete opposite end.
The Template Barnstar
I've begun to include the Episode list template into the List of South Park episodes page. Before the template was made, the WikiProject was pretty much dead. Thanks for your hard work into making this a reality! Here's a barnstar to show my appreciation. Will2k 03:21, 12 June 2006 (UTC)

Past wikiwork
I used to be very active in Wikipedia:WikiProject Television and its subprojects that are now taskforce. However after several heavy disputes within the community, I decided it was best to avoid this topic within Wikipedia and left that project.
