Ph.D. student in computer science at Norwegian University of Science and Technology.
My primary focus on wikipedia is adding technical content.
My [http://www.idi.ntnu.no/~fredrior/ homepage]. Norwegian [http://no.wikipedia.org/wiki/Bruker:Orderud wikipage]. [http://en.wikibooks.org/wiki/User:Orderud Wikibooks] homepage.
Check my Wikipedia [http://kohl.wikimedia.org/~kate/cgi-bin/count_editsuser=orderud&dbname=enwiki editcount]. I ll soon reach 2000 edits! :) My recent [http://en.wikipedia.org/wiki/Special:Contributions/Orderud contributions].
