A computer-implemented system and related method address malfunctioning peers in a blockchain, the method comprising receiving endorsement results from peers in the blockchain, where the endorsement results are for one or more transactions in the blockchain. The endorsement results include successful and failed endorsements. The method further comprises distributing the successful and failed endorsements to two or more endorsement collectors, determining which peers are successful endorsement peers (SEPs) that provided successful endorsements, and which peers are failed endorsement peers (FEPs) that provided failed endorsements. A reputation score is calculated for each peer based on endorsement information from the endorsement collectors. The reputation score is then sent to at least one of a client and a system administrator. This reputation score is then used to determine peer selection in a subsequent transaction.

A system and method are provided for measuring the performance of a synthetic peer-managed content distribution network. Each node peers with one or more other nodes to share the content and facilitate its presentation to associated users. Each node collects session metadata for identifying the node's environment, presentation events regarding presentation of the content to users, and transfer events regarding the sharing of the content among peers. The nodes report their data toward a central entity that feeds the different types of data through different ETL pipelines to obtain the performance measurements. For example, the session metadata may allow the reach of a content item to be determined, the presentation events may be used to determine the quality of experience with the content item for users, and the transfer events may be used to determine how much external bandwidth the network conserved and/or how efficiently the nodes shared the content.

A system for exchanging GPS or other position data between wireless devices for purposes of group activities, child location monitoring, work group coordination, dispatching of employees etc. Cell phones and other wireless devices with GPS receivers have loaded therein a Buddy Watch application and a TalkControl application. The Buddy Watch application communicates with the GPS receiver and other wireless devices operated by buddies registered in the users phone as part of buddy groups or individually. GPS position data and historical GPS position data can be exchanged between cell phones of buddies and instant buddies such as tow truck drivers via a buddy watch server. Emergency monitoring services can be set up with notifications to programmable individuals in case an individual does not respond. Positions and tracks can be displayed. TalkControl simplifies and automates the process of joining talk groups for walkie talkie services such as that provided by Nextel.

An image processing unit 118 generates a distribution image including a game image. A distribution processing unit 126 distributes the distribution image to one or more of information processing terminals through a shared server. A participation processing unit 128 accepts play requests of viewing users operating the information processing terminals and approves a game play of one of the viewing users who has made a request for a play. An application execution unit 110 processes a game using operation information transmitted from the information processing terminal operated by the viewing user the game play of which has been approved.

The present disclosure provides an apparatus and method for sharing content. A method provided in the present disclosure comprises receiving a message to request to join a content sharing group from a second device while a third device included in the content sharing group transmits first content shared in the content sharing group to a fourth device included in the content sharing group, adding the second device to the content sharing group, and permitting the second device to access the first content.

A device may include a memory storing instructions and processor configured to execute the instructions to receive, by a first blockchain node and via a first base station, a message from a first Internet of Things (IoT) device to a second IoT device, wherein the device corresponds to a first multi-access edge computing (MEC) device located in a first MEC network associated with the first base station. The processor may be further configured to authenticate, by the first blockchain node, the first IoT device using a blockchain associated with a group of IoT devices and send, by the first blockchain node, the message to a second blockchain node in a second MEC device in a second MEC network associated with a second base station servicing the second IoT device, in response to authenticating the first IoT device using the blockchain associated with the group of IoT devices.

A network device includes a processor and a memory. The processor effectuates operations including instantiating an edge share orchestrator that identifies edge devices including a customer device. Edge share orchestrator also determines that the customer device lacks computing power or functionality to perform at least a portion of an existing or augmented service and identifies at least one additional device of the edge devices capable of providing additional computing power or functionality for performing the at least a portion of the existing service or augmented service associated with the customer device. Edge share orchestrator also meshes the additional computing power or functionality of the at least one additional device with the customer device and performs the at least a portion of the existing or augmented service associated with the customer device using the meshed additional computing power or functionality of the at least one additional device and the customer device.

An electronic device of a first user is configured to: connect with a second electronic device of a second user of the plurality of electronic devices over a first peer-to-peer wireless network link when the second electronic device is within a communicable range of the first electronic device; receive from the second electronic device, a second unique code generated by the second electronic device, the second unique code including a second unique identifier of the second electronic device; store on the first electronic device: the second unique identifier; information associated with the proximity of the second electronic device; and information associated with the time when the second electronic device is within the communicable range of the first electronic device; and display a notification on the first electronic device when the second unique identifier is downloaded from a web server to the first electronic device.

In a running distributed data storage system that actively processes I/Os, metadata nodes are commissioned and decommissioned without taking down the storage system and without introducing interruptions to metadata or payload data I/O. The inflow of reads and writes continues without interruption even while new metadata nodes are in the process of being added and/or removed and the strong consistency of the system is guaranteed. Commissioning and decommissioning nodes within the running system enables streamlined replacement of permanently failed nodes and advantageously enables the system to adapt elastically to workload changes. An illustrative distributed barrier logic (the “view change barrier”) controls a multi-state process that controls a coordinated step-wise progression of the metadata nodes from an old view to a new normal. Rules for I/O handling govern each state until the state machine loop has been traversed and the system reaches its new normal.

A movable table may be configured to support a patient. The movable table may comprise a communication interface configured to communicatively couple with a medical device. The movable table may also comprise one or more processors and a non-transitory machine-readable medium comprising a plurality of instructions which, when executed by the one or more processors, cause the one or more processors to perform operations. The operations may include transmitting, via the communication interface and to the medical device, information relating to a planned motion of the movable table and receiving, via the communication interface and from the medical device, a response to the information relating to the planned motion of the movable table. Based on the response received from the medical device, the operations may include selectively causing performance of the planned motion of the movable table.
