[vpribish]

who is your audience? where are they starting from? know this before going in.

get there very early and check that the tech is sorted.

have a short list of explicit goals - feel free to write them out.

practice at least once, for real, out loud. If no one will help, present the talk to a stuffed bear.

do not read your slides to the audience.

expect live demos to fail - have a practiced contingency plan.

no lewd illustrations and don't put people down - you are in a position of responsibility.

at the end, sum up.
