Just got a nice note from David Kohanbash with a pointer to his blog entry on debugging. He was going to post his own rules on debugging, but then found the DebuggingRules! poster and decided to organize his thoughts around that, without having read the book (it was on order.) Very interesting to read–he gets it right (at one point even quoting the same Sherlock Holmes line that I use).
I guess this shows that universal concepts are independently discoverable.
And once he got the book, he confirmed all this, and highly recommended it. So, thanks for the plug, David!
