Probably coined many times before me, but any how, my first law:No matter how many times you proof an email for posting to a listserv, an obvious error will always become immediately apparent when you read the copy of the message the list sends back to you after posting.
I think we should add a question to the ITLab interview question list. “Have you ever written a weather grabbing/parsing/caching app?” Much like every app. must evolve till it can send email, writing such an app. seems to be a rite of passage of any possibly decent coder.
