My work at Wikipedia[edit]

I mainly program templates and edit articles about cryptography. I mostly work on the English Wikipedia but sometimes I fix stuff on the Swedish and German Wikipedias and on Meta too.

About me[edit]

I was born in 1969 and I am a native of Gothenburg/Göteborg on the Swedish west coast. That's in Scandinavia in northern Europe. I speak Swedish, English and German and understand the Scandinavian languages.

If you want to know more about me go to my web site, (English) or (Swedish).

My day job is the Randpeer project.

I like Wikipedia since it has provided me with answers to many of my questions during the last few years. So naturally I wanted to join in and make Wikipedia even better.

I think Wikipedia is like the web on steroids. And I think that Wikipedia might become the best encyclopaedia the human race has ever seen (if it isn't already). Apart from the web itself that is. But hey, Wikipedia is a part of the web...

I started editing Wikipedia in September 2004 when I saw a red link to filmjölk in an article about Swedish food. And I immediately got hooked. (Now that link to filmjölk sure isn't red anymore!) But I think I will have much more to contribute over time since I am an engineer, researcher and teacher by profession and by habit. By the way, I have used computers since 1982, Fidonet since 1990 and the Internet since 1991. So yeah, I am an old computer geek.

As usual in Wikipedia if you want to communicate with a user (me in this case) leave a message on my talk page. As you might know Wikipedia automatically informs me of any new messages/edits on my talk page when I log in.

Articles and pages I started out[edit]

  • Filmjölk - A kind of food that we eat in Sweden and some other countries. Unfortunately the article came under extensive attack by some Finns so I gave up on it and left it. However the wiki process seems to work, over time other editors have made it better and in the end the attackers gave up.
  • Hash list - A method used to detect errors in data such as files in for instance p2p networks.
  • Hash tree - Another method used to detect errors in data such as files in for instance p2p networks.
  • Naprapathy - A kind of manual medicine similar to chiropractic.
  • One-way compression function - Well, really a merger and major rework and extension of three small articles.
  • Merkle-Damgård construction - Based on a section that was in two other articles. I cut them out and reworked and extended the text.
  • Ivan Damgård - Translated the french article using
  • Key strengthening - Cryptographic methods to make weak keys such as passwords stronger.
  • Clock drift - Well, really a major rework and extension of the original small and confused article.
  • Keystream - A concept in cryptography.
  • Shared secret - Unbelievable that such a common and simple concept in cryptography did not already have an article.
  • Wikipedia:Ambox CSS classes - A Wikipedia how-to-guide related to the {{ambox}} project.
  • Wikipedia:Line break handling - The definitive "how-to guide" about how to handle word wraps (line breaks) at Wikipedia.
  • Wikipedia:Editnotice – About the editnotice system.
  • Wikipedia:MediaWiki messages – The central page to discuss MediaWiki interface messages.
  • Wikipedia:Secure server – About the Wikimedia secure server.
  • MediaWiki:Accountcreator.css, MediaWiki:Ownuserspace.css – The global CSS-files loaded for accountcreators and when a user edits his/her own user or user talk page. Used in the editnotice system.

Articles I have made images for[edit]

Templates I made[edit]

Templates I created or done major reworks of. Some have of course been teamworks:








  • {{check file on delete}}, {{check page on delete}} – Called from the image and page delete system messages. Checks if a page is protected and displays a warning message when an admin tries to delete that page.

User scripts I made[edit]

My other Wikipedia accounts[edit]

I use unified login thus any account on any other Wikipedia or MediaWiki project with the same name usually is me too.

Below are my alternate accounts here at the English Wikipedia. So far I have only used them for some testing. I might use them in the future if I ever feel the need to log in and edit from an insecure public computer or similar.

Images I created and uploaded[edit]

Some of these pictures have of course been teamworks, some are just minor edits, and some have been reused in printed books.

Unused pictures[edit]

Perhaps to be deleted.


I was on a long wikivacation between September 2007 and February 2008.

To remind myself why I went on wikibreak, here are some of the reasons:

  • I reached a way too high level of wikistress while working in a bigger project here at Wikipedia summer 2007.
  • Templates I created and was still working with and that sometimes were not even deployed anywhere yet were often taken over by admins by them protecting the templates so only they could edit them. It is very frustrating to not be allowed to finish ones work.
  • Admins have several times deleted text and even blanked entire pages in my user space without leaving an explanation in their edit comments nor on my talk page. When I ask them why they usually respond rudely or don't respond at all. (I guess it is a bit stressful for them to see copies of high risk templates such as {{pp-meta}} with padlocks and all in someone's user space, so they just blank the page. They didn't realise I created that template and was still doing work and testing on it.)
  • I was smacked by admins for keeping track of some vandals. Apparently vandals are allowed on Wikipedia and you are not allowed to fight them if they make "legal threats" against Wikipedia.

Since I am now an admin myself: I hope this list will help me remember, so I won't behave like that. And avoid terms like "no harm done" and "assume good faith", they are only provocative.
