Rush Hour
Instead of cluing crosswords (what I should be doing), I've been trying to figure out these logic puzzles. Great fun.

5:11 until I got stumped at Level 8.

24:38 for all 12 levels, but that included a trip downstairs for an extra pastry and some quality time in a debugger. (Do any rsn geeks know how to tell gdb "break in function f(), but only if function f() has been called by function g()"?)

no.

As much as I loathe Visual Studio (maybe because I'm still using ver. 6), I use it for debugging because gdb scares the bejeezus out of me.

VS has its charms, for sure, but scripting breakpoints is not one of them, as far as I can tell. Plus, this is a 32-bit-Linux-only problem, so it's not an option for me anyhow.
Answer: In gdb, breakpoints can have associated commands that execute when the breakpoint is hit. I put two "breakpoints" in g(), one each before and after the call to f(). The first one sets a gdb variable to 1 and continues program execution. The second sets that variable back to 0 and continues. Then, I put a conditional breakpoint in f() that is only triggered when that variable has a value of 1. Works awesome.
I apologize for hijacking a perfectly good logic puzzle thread. It won't happen again.

41:44 for 12. The last one took me ...16 minutes?? I can't believe I just clicked that long.
