"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, co-operate, act alone, solve equations, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialisation is for Insects" - Robert A Heinlein

I've tried to take this view of broadcast engineering - a competent engineer should be able to re-head a VTR, rack a studio camera, install the OS & software so as to make an Avid work, repair & colour balance a monitor, line-up an audio compressor and be able to drive AutoCAD.
