O.k. I'll admit that maybe the Boulder one was tweaking the nose a little, but I deemed it sufficiently obvious not to cause a problem in solving it - I've seen a lot dodgier ones anyway.
With regards the capital one : The executioner's chopping board was known as the block capital (admittedly perhaps only poetically) as it was the block on which capital punishment was "executed".
I reinstalled win2k on my laptop tonight. In the space of ~45 minutes between installing the network driver and a firewall, I was hit by a worm. Sometimes I wonder why I bother.
[Nik] This is pretty much exactly why I'm tending to install non-packaged Linux distros; something like Gentoo encourages you to choose exactly which services to turn on rather than the (for example) Red Hat approach of turning everything on and assuming you will remember to turn everything off before you attach your box to the net.
