Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for efficient media indexing. An example method disclosed herein includes means for initiating a list of hash seeds, the list of hash seeds including at least a first hash seed value and a second hash seed value among other hash seed values, means for generating to generate a first bucket distribution based on the first hash seed value and a first hash function and generate a second bucket distribution based on the second hash seed value used in combination with the first hash seed value, means for determining to determine a first entropy value of the first bucket distribution, wherein data associated with the first bucket distribution is stored in a first hash table and determine a second entropy value of the second bucket distribution.

Abstract: Modular drop-glass window assemblies include a vertically slidable pane, at least one stationary pane having an inboard vertical edge proximate to the exterior surface of the slidable pane and framing holding the stationary pane(s) and at least partially defining a window opening that is opened and closed by movement of the slidable pane. The framing includes vertical frame portions defining run channels for guiding the slidable pane between its open and closed positions. No portion of the vertical frame portions extends exteriorly beyond the plane of the exterior surface of a stationary pane.
