Every few years, when the volume of keys on my keyring amounts to a tympanic, spike laden tennis ball of metal, like something from the mind of Marcel Duchamp, I do a purge.
I'm back from vacation and from the XML Summer School in Oxford. The Summer School was fun. A unique event. A bit like a Geek Cruise but floating in a flotilla of ancient college in a sea of fantastic museums, libraries and bookshops.
