Robert Graham over at Errata Security has a very interesting post up. The topic of the post is confirmation bias, a well-known concept in science that revolves around the idea that a theory is only valid when you can not disprove it (rather than when you can prove it).
"Because of this, the first time somebody misconfigures BitTorrent to use too many connections, the router crashes. Likewise, internal processes within the router crash often and silently restarting without
being visible from the outside - but still passes QA tests because they
aren't looking for that. Anything unusual that the user does is likely
to cause a crash."
Definitely an interesting read.
