p 12: Obsolescence-Proof Your UI (Part 2): Web Server Strategy, By Steve Hendrix

Definition of “Wedged”:  A “wedge” is an older technique, less commonly used today, whereby a programmer would add functionality to an existing program (often a device driver) by inserting a call to his custom function in the middle of that existing program. In this way, he could leverage the work already done in the device driver, but add a new function. As an example, I inserted a wedge in the keyboard driver of my very first PC, an Ohio Scientific Superboard II, to remap the keyboard to the Dvorak arrangement. In much the same way, this “wedge” deflects your attention from the mainline text to add a bit of functionality!
