Abstract: A computer-implemented method, system, and computer program product are provided. A processor defines and stores units of image data of a container image, where the units of image data are compressible. A processor represents the units as nodes in a dependency graph for a container image, including one or more nodes at a dependency level in the dependency graph.

Abstract: A node in a blockchain network may invoke a process comprising receiving one or more operations for inclusion in a block, receiving a previous Merkle root created from previously determined account dispositions from a previous block, resolving the one or more operations based on the previous account dispositions to determine one or more current account dispositions, creating a current Merkle root for the one or more current account dispositions, and hashing current data for the current block, the data comprising the current Merkel root and the previous Merkle root to generate an account disposition block.

Abstract: In combination with a track assembly having a lower track defining a lower channel spanning a length of the lower track and defining a center plane, wherein an improvement is disclosed that includes having a laser level operably configured to emit a laser in a direction away from an laser output of the laser level in a laser emission plane and having a laser level track attachment device coupled thereto. Further, the improvement includes the laser level track attachment device having a body with a cantilever member that projects in a direction opposite to the direction in which the laser is operably configured to be emitted from the laser level and is sized and shaped to be complementarily received within the lower channel of the lower track such that the laser emission plane is substantially coplanar with the center plane of the lower channel.

Abstract: Disclosed is a device for stabilizing a limb, e.g., to which a health care device is secured, and providing for anti-rotation thereof in a health care setting. In an embodiment, the device includes a base section, and two side sections attached to the base section and extending therefrom to define a trough-shaped channel or a rectangularly-shaped channel. Each side section includes a plurality of discontinuities with edges extending longitudinally along an interior side thereof. The discontinuities provide engagement with a limb or health care device within the channel to resist bi-lateral rotation thereof in the channel. A similar embodiment includes one side section and provides unilateral anti-rotation resistance.
