I know I'm late to the party on this one, but I just used gitbisect for the first time today in order to hunt down where akernel bug started showing up. Since there are more kernel bugs in my future, here are some things that I want toremember about the process and other random comments.

(I'll probably have more later when I do it again.)

First, I have to say that the whole process really is both cool andaddictive, and it works.

Suppose that you want to find all two and three digit primes where allof the component digits are also prime (eg, 37 would qualify but 41would not, since 4 is not prime).

Here is the simple Unix approach:

factor $(seq 10 999) | awk 'NF == 2 {print $2}' | egrep '^[12357]*$'

(I won't claim that this is obvious until you're immersed
