About me

My name is Derk-Jan Hartman. I used to edit, but now I mostly deal with tech stuff. I'm a volunteer contributor to the MediaWiki software that runs Wikipedia, dealing with things like accessibility, scripting, CSS, small bugs, mobile, video and so much more.. A long time ago I was one of the volunteer developers of VLC media player.

ToDo

  • line numbers in diff view (argument, creates context for position within the document... requires knowing total line count as well)
  • √ Fix print of collapsible content T152330
  • √ Update map box/leaflet.js
  • Finish writing gadget example (stalled)
  • Collect all map layers and base maps we have in a demo
  • Make the maps stuff reusable, awesome (stalled)
  • Reimplement Vector using CSS grid

I still occasionally provide support to English Wikipedia, but really only if it is in the interest of furthering MediaWiki and/or the global and diverse Wikimedia movement.
