rattus rattus’ blog

Linus 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.

There is a wonderful quote by Heinz von Foerster that I first learned about at a workshop in April 1991 in Vienna where he presented it in his opening talk:

The problem is not truth,
the problem is trust.

This is a very riddle. One can read it in many ways, and every time I look at it it’s likely to tell me another story. I am most thankful to Heinz von Foerster that he suggested 2 things for reading this riddle: Look up the words in an etymological dictionary, and … silence. He just looked into my eyes and smiled.

May I invite you to see for yourselves. Here is the quote with links to the Online Etymology Dictionary:

The problem is not truth,
the problem is trust.

In an opening address for a conference in 1990, see “ethics and second-order cybernetics“, Heinz von Foerster tells a story about the origin of the quote.
