  • Publication number: 20180176296
    Abstract: A method, including deploying multiple servers as a distributed computing system (DCS) configured to provide a service to clients. At a first time, a given server is configured as an active node in the DCS, the active node configured to and to process requests for the service received from the clients. At the first time, one or more remaining first servers are configured as one or more semi-active nodes in the DCS, each given semi-active node configured to receive, from the clients, requests for the service, and to forward the received requests to the active node for processing. Each of the servers maintains respective counts of the received requests, and at a second time subsequent to the first time, upon identifying a given remaining server having a highest count the given remaining server is reconfigured as the active node, and the given server is reconfigured as a semi-active node.

  • Publication number: 20180173718
    Abstract: Various embodiments for enhancing storage of deduplicated data in a computing storage environment. Analytics are applied to at least one data storage characteristic observed in the computing storage environment to restructure the deduplicated data in a more sequential manner so as to enhance performance of the computing storage environment. A type of storage device associated with the deduplicated data is monitored, and the analytics are withheld from application when the type of storage device is determined to be a solid-state device. The restructuring of the deduplicated data in the sequential manner is performed by comparing the at least one data storage characteristic against at least one predetermined thresholds, one of the at least one predetermined thresholds prohibiting a particular block of the deduplicated data from being restructured when the particular block of deduplicated data has been previously moved in the computing storage environment within a predefined timeframe.

  • Publication number: 20180176322
    Abstract: At an application executing in a system, a usage pattern of the system and an entry in a data use history of the system are analyzed. Responsive to the analyzing, a data item is identified for caching at the system, wherein the data item is accessible to the system from at a remote data processing system over a data network at a present time, and the data item will be requested from the system at a future time when no network connectivity will be available to the system. A determination is made whether a caching control prevents the caching of the data item at the system. Responsive to the caching control not preventing the caching of the data item, the data item is cached on the system.

  • Publication number: 20180172745
    Abstract: A subset of mobile devices is selected from a set of mobile devices located in a local area. From a mobile device in the subset, a magnetic measurement value obtained by performing a magnetic measurement is received. The magnetic measurement value comprises a change in a magnetic property of an immediate surrounding ambient environment of the mobile device. When the magnetic measurement corresponds to a deviation in a network condition in a portion of a network, the portion being located in the local area, a conclusion is output that the deviation is caused by an electromagnetic disturbance (EMD), where an effect of the EMD causes the magnetic measurement value. A notification including an indication of the EMD and an identification of the local area is generated.

  • Publication number: 20180176137
    Abstract: At an application executing in conjunction with a vSwitch in a host system, a CWND value is computed corresponding to a flow from a VM using a period measured by a timer and a number of packets of the flow received and acknowledged in response packets, the number being counted by a counter, the timer being associated with a packet of the flow. The CWND value is stored in a field in a response packet received from a receiver of the flow, the field being designated for carrying a RWND value, the response packet corresponding to a packet in the flow. The storing forms a modified response packet.

  • Patent number: 10001916
    Abstract: A mobile device includes a directional streaming mechanism that causes digital content to be streamed to one or more nearby devices based on a gesture on the touch screen of the mobile device, such as the swipe of a finger. The mobile device and nearby devices each include a position mechanism that allows each device to know the position of other devices within a given range. When a user is streaming digital content to the mobile device, the user can swipe a finger on a touch screen display in the direction of one of the streaming devices in range of the mobile device, which results in the mobile device streaming the digital content to the streaming device in the direction of the finger swipe. The streaming device in the direction of the finger swipe can then play the digital content received from the mobile device.

  • Patent number: 9999805
    Abstract: Systems, methods, and computer-readable media are disclosed for capturing, over the course of a sports match, gaze data for each participant on a team, identifying a team-level key performance indicator (KPI) associated with a sports domain to which the sports match corresponds, and generating KPI data corresponding to the KPI. A graph may then be constructed based at least in part on the KPI data, where each node in the graph may represent a player on the team or an object of interest, and each edge connecting adjacent nodes may be weighted to indicate a degree of interaction between the nodes connected by the edge. KPI data may be aggregated across multiple sports domain KPIs and analyzed to assess team performance characteristics during the sports match. Report data indicative of team performance for different game scenarios, and optionally including recommendations for improving team performance in such scenarios, may be generated.

  • Patent number: 9999905
    Abstract: Polymeric coatings and methods of forming polymeric coatings are described. In a method of forming a polymeric coating a first layer is deposited on a substrate. The first layer includes at least one highly soluble diamine component. A second layer is formed on the substrate to contact the first layer. The second layer includes paraformaldehyde and an aromatic diamine including two primary amine groups. Once formed, the first and second layers are heated. Heating causes the components of the first and second layers to cure. For example, the paraformaldehyde from the second layer diffuses into the first layer and reacts via hemiaminal-type chemistry with the high soluble diamine component. The coatings may be substantially homogenous or comprise a compositional gradient in thickness or along the substrate plane depending on deposition methods and other processing parameters.
