I was doing a tutorial this morning and I had just run the program when all the power in the building went off. The students present were most impressed, they had never seen a program that could turn off all the lights.
Fortunately (or unfortunately) it turned out that it wasn’t my code. The power came back on after five minutes or so, and later on we got an email saying that owing to problems at the local sub-station we would have to shut down the university and leave early as “any delay could cause catastrophic problems”.
I had this vision of people standing around a pair of glowing wires and someone playing the Scotty role and saying things like “I dinnae think she’ll take much more captain..”
Unfortunately it meant postponing my 4:15 VB lecture. Sorry about that folks, we were going to learn all kinds of interesting things about file paths too….
