Many data centers have a hack or two or more.
In modern computing terminology, a kludge (or often a "hack") is a solution to a problem, doing a task, or fixing a system that is inefficient, inelegant, or even unfathomable, but which nevertheless (more or less) works. To kludge around something is to avoid a bug or some difficult condition by building a kludge, perhaps relying on properties of the bug itself to assure proper operation. It is somewhat similar in spirit to aworkaround, only without the grace. A kludge is often used to change the behavior of a system after it is finished, without having to make fundamental changes. Sometimes the kludge is introduced in order to keep backwards compatibility, but often it is simply introduced because the kludge is an easier alternative. That something was often originally a crock, which is why it must now be hacked to make it work. Note that a hack might be a kludge, but that 'hack' could be, at least in computing, ironic praise, for a quick fix solution to a frustrating problem.
The folks at Open Compute have figured out that Hacks are the reality of data center operations and sharing your hacks help them get better.
