Abstract: Systems and methods for managing a storage device are disclosed. A first amount of a first storage device is associated to a first client. A first request associated with first data is detected, and a second request associated with the first data is also detected. A log for the first request and the second request is maintained for the first client. A trigger condition is identified, and based on identifying the trigger condition, a value is computed based on the log. A second amount of the first storage device is determined based on the value, and the second amount is associated to the first client.

Abstract: One embodiment of a system of the present disclosure, among others, can be implemented as follows. A modular wall block system includes a plurality of wall blocks comprising first wall blocks of a first shape and second wall blocks of a second shape and at least one continuous passageway running from a top of a wall to a bottom of the wall formed from the plurality of wall blocks. The wall blocks are configured such that the at least one continuous passageway is formed when a plurality of blocks are laid side by side in a tier and stacked one atop of another to form an additional tier. In a further embodiment, the wall blocks also include third wall blocks of a third shape. Other systems and methods are also provided.

Abstract: One embodiment of a system of the present disclosure can be implemented as follows. A plurality of wall blocks are stacked to form at least a portion of a retaining wall, each wall block having an interior face, an exterior face; a top surface, and a bottom surface. The system further includes retaining means for securing at least one reinforcement member between stacked wall blocks, the retaining means including a pair of reinforcement member retaining bars that are positioned within a slot crossing the transverse length of the top surface of at least one wall block. A first of the retaining means secures the at least one reinforcement member against the bottom of the slot and a second of the retaining means secures the first retaining members against the side of the slot, such that the at least one reinforcement member is additionally secured between the pair of retaining means. Other systems and methods are also provided.
