Idiot

Me, that is.  And also others.
Idiocy on my part?  Forgetting my power brick at the conference.  A forgiveable (and as it turns out, fixable, by running for a bus, sprinting up the stairs, and finding the power brick ten minutes before the room was deconstructed by tech guys) mistake.  The bigger mistake?  The organizers of the conference decided in their infinite wisdom that the laptops they were letting people use should be collected prior to the open session where we were going to get people playing around with software.
Oh well. Tant pis.  We'll submit a suggestion to next year's conference to do things in a more ---- organized ---- fashion.

Yours, glad to have got my power brick back,
N.
