Once upon a time, in a kingdom not far from here, a king summoned two of his advisors for a test. He showed them both a shiny metal box with two slots in the top, a control knob, and a lever.
“What do you think this is?”
One advisor, an Electrical Engineer, answered first.
“It is a toaster,” he said.
The king asked, “How would you design an embedded computer for it?”
