Hans Reiser is the creator of the Linux file system ReiserFS, and a convicted murderer. In 2006 he murdered his wife. He was convicted in 2008. Reiser's defense -- the so called geek defense -- was that as a geek, and possibly on account of Aspergers Syndrome, he did not understand that his actions in the aftermath of Nina Reiser's disappearance would look like attempts to cover up a murder. When asked if he was "dysfunctional in every social setting" by his defense attorney, he said "Except in being a scientist". This is an extreme case of He's just like that: an attempt to excuse anti-social behaviour because geeks can't help behaving that way.
