Debugging
December 19th, 2008Linus Torvalds, recently wrote about debugging hell in his private blog. What I read is a wonderful variation of Paul Watzlawick’s story of a man who is looking for his keys where the lantern shines instead of where he lost them:
Torvalds was desperately looking for the solution of a serious problem which seemed to occur only spontaneously and at a time where it could not be observed, analyzed or tracked. Later, a method was found which allowed to trigger the problem but it apparently had “nothing what-so-ever to do with the actual failure itself”. Eventually, colleagues found “the real clue” by looking at one incident where the problem did not occur.
