Abstract: A system receives a request to store a replica of a data object into any cloud storage node associated with an attribute, and then identifies a redundancy number associated with the data object. The system identifies a number of cloud storage nodes that are associated with the attribute. If the identified number of cloud storage nodes is greater than the redundancy number, the system identifies the redundancy number of cloud storage nodes as a subset of the number of cloud storage nodes, based on the data object and a unique identifier associated with each of the number of cloud storage nodes. The system stores the redundancy number of replicas into the corresponding redundancy number of cloud storage nodes.

Abstract: The invention relates to an organic light-emitting diode (OLED) display device and a manufacturing method thereof. In the invention, a first retaining wall corresponding to a bending region is configured to include first retaining wall units spaced apart from each other, and a first buffer structure is formed in a gap provided between the first retaining wall units and is alternately connected to a left side and a right side of the first retaining wall units. This can prevent excessive stress concentration on the retaining wall in the bending region due to its special configuration, which causes a phenomenon of film layer detachment. Therefore, a failure of the OLED display device is prevented.

A crack preventing member is filled in the first groove and is connected to the substrate, so a connection of the organic layer to the organic layer is achieved, thereby increasing a bending resistance of the display panel and reducing the risk of film peeling. In addition, a side surface of the interlayer insulating layer disposed between the first groove and the banks away from the substrate is partially recessed to form a second groove, and the first inorganic packaging layer is filled in the second groove. An inorganic layer of the packaging layer is connected to an inorganic layer of an array substrate, thereby increasing a bending resistance of the display panel and reducing the risk of film peeling.

Abstract: A system identifies a data object, stored in a client, for replication. The system identifies a redundancy number associated with a protected amount of failed storage nodes. The system determines whether the total count of available storage nodes is at least two greater than the redundancy number. The system determines a distribution number that is at most the total count minus the redundancy number, in response to a determination that the total count of available storage nodes is at least two greater than the redundancy number. The system creates erasure code for the data object. The system allocates the distribution number of sections of a replica of the data object to a corresponding distribution number of available storage nodes and the redundancy number of sections of the erasure code to the redundancy number of available storage nodes, which excludes the corresponding distribution number of available storage nodes.

Abstract: A display panel and a display device are provided and have a base substrate, a blocking wall, an encapsulation layer, and a touch capacitor layer. By forming a second-layer blocking wall and a first-layer blocking wall to form a second blocking wall, a height of the second blocking wall is increased. Further, a blocking block is disposed between the second blocking wall and the first blocking wall, thereby increasing a thickness and a height of the blocking wall. When inkjet printing an organic layer, a slope at edges of a display area is relatively smooth, which can make an entire encapsulation layer relatively flat, thereby reducing a height difference of wirings at the edges and avoiding a problem of inaccurate exposure and focus.
