oldbloke's mutterings

Yesterday's Graun's sudoku turns out to be one my prog can't do.
Given that I'm having a spot of bother with it by hand, this is actually good: it means I haven't missed something dead obvious.
The output shows a simple mod will get the prog a bit further, but I still don't think it'll finish it

well, a mouse, anyway.
and it's gone now - we eventually caught it and chucked it out.
we assume Felix brought it in and then failed to kill/eat it.
i was just gazing at the tv, thinking about getting myself a drink, when it wandered across the room.
took a while to catch it...
