highly adv. [scientific computation] The preferred modifier for overstating an understatement. As in: highly nonoptimal , the worst possible way to do something; highly nontrivial , either impossible or requiring a major research project; highly nonlinear , completely erratic and unpredictable; highly nontechnical , drivel written for luser s, oversimplified to the point of being misleading or incorrect (compare drool-proof paper ). In other computing cultures, postfixing of in the extreme might be preferred.
