This was originally formulated in Eric Raymond’s essay The Cathedral and the Bazaar . The relevant section is quoted below:
Linus was behaving as though he believed something like this:
8. Given a large enough beta-tester and co-developer base, almost every problem will be characterized quickly and the fix obvious to someone.
Or, less formally, ``Given enough eyeballs, all bugs are shallow.’’ I dub this: ``Linus’s Law’’.
My original formulation was that every problem ``will be transparent to somebody’’. Linus demurred that the person who understands and fixes the problem is not necessarily or even usually the person who first characterizes it. ``Somebody finds the problem,’’ he says, ``and somebody else understands it. And I’ll go on record as saying that finding it is the bigger challenge.’‘
