  • Publication number: 20190306249
    Abstract: An endpoint system provides a REST endpoint for an application. The endpoint system processes request messages based on message pair data for each message that includes an operation and parameter data. The parameter data includes parameter information for each parameter that identifies whether the value for the parameter is to be taken from the URI or payload of a request message. The endpoint system receives request messages that have a URI and payload. The URI includes an operation name. The endpoint system processes each request message in accordance with the message pair data for the operation specified in the request message. For each parameter of the message pair data, the endpoint system extracts the value for the parameter from either the URI or payload as specified by the parameter information for the parameter. The endpoint system then invokes the operation passing the one or more extracted values as actual parameters.

  • Publication number: 20190306238
    Abstract: Systems, methods, and computer-readable media for an adaptive gossip protocol. A node in a cluster can detect a gossip protocol synchronization triggering event which can include an indication that the node has received data from a second node via a gossip protocol, an update to data maintained by nodes in the cluster, and/or an operation. In response to the triggering event, the node can determine a dynamic gossip interval for disseminating data from the node to other nodes via a gossip protocol, the dynamic gossip interval being based on a synchronization state associated with the cluster and/or one or more gossip protocol events associated with the cluster. Next, the node can select a third node in the cluster for disseminating the data from the node to the third node. The node can then transmit the data to the third node via the gossip protocol based on the dynamic gossip interval.

  • Publication number: 20190284102
    Abstract: Provided herein is a composition for use as a hardening regulator, e.g. hardening accelerator or hardening retarder, for building materials, as well as methods for producing thereof. The composition is characterized by a biphasic nature in which solid calcium silicate nanoparticles are dispersed in an aqueous solution comprising inorganic water soluble iron, and possibly zinc, silicate and calcium, species. Additional components such as inorganic ions and silica nanoparticles can be present. Depending on the relative ratio of each component, the composition can be used either for retarding or for accelerating the hardening process of a building material such as cement or concretes. The so-obtained building material further shows an enhanced strength upon compressive forces applied thereon.

  • Patent number: 10412445
    Abstract: An example implementation involves a playback device receiving a request to add continuous automated streaming audio content to a playback queue, the request indicating a playback start time, and the playback queue indicating a plurality of audio content. The implementation further involves the playback device adding the continuous automated streaming audio content to the playback queue. The example implementation also involves the playback device determining that a duration until the playback start time is less than a duration of the given audio content before playing a given audio content in the playback queue. The example implementation involves the playback device responsively, playing the continuous automated streaming audio content.

  • Publication number: 20190228034
    Abstract: A first connection state may be entered on a computing device. While the computing device is in the first connection state, actions taken on a playlist on the computing device may be applied to the playlist and not applied to a playback queue associated with a zone. An input may be received via the computing device, indicating a selection of the zone. In response to receiving the input, a second connection state may be entered. Entering the second connection state may comprise establishing a connected state between the computing device and the one or more playback devices. While the connected state is established, one or more actions taken on the playlist on the computing device may be applied to the playlist and transmitted, in a message to the zone over a network. The one or more actions may be one or more corresponding actions applied to the playback queue.

  • Publication number: 20190220760
    Abstract: In one embodiment, a network assurance system that monitors a network labels time periods with positive labels, based on the network assurance system detecting problems in the network during the time periods. The network assurance system assigns tags to discrete portions of a feature space of measurements from the monitored network, based on whether a particular range of values in the feature space has a threshold probability of occurring during a positively-labeled time period. The network assurance system determines a set of the assigned tags that frequently co-occur with the positively-labeled time periods in which problems are detected in the network. The network assurance system causes performance of a mitigation action in the network based on the set of assigned tags that frequently co-occur with the positively-labeled time periods.

  • Publication number: 20190215230
    Abstract: In one embodiment, a network assurance system discretizes parameter values of a plurality of time series of measurements obtained from a monitored network by assigning tags to the parameter values. The network assurance system detects occurrences of a particular type of failure event in the monitored network. The network assurance system identifies a set of the assigned tags that frequently co-occur with the occurrences of the particular type of failure event. The network assurance system determines, using a Bayesian framework, rankings for the tags in the identified set based on how well each of the tags acts as a predictor of the failure event. The network assurance system initiates performance of a corrective measure for the failure event based in part on the determined rankings for the tags in the identified set.

  • Publication number: 20190208262
    Abstract: An example first playback device includes programming to perform functions including receiving a first request to associate with a first playback queue that is stored remotely from, and persists unassociated with, any playback device of the media playback system. The functions also include associating with the first playback queue and designating the first playback queue as an active queue of the first playback device. The functions also include receiving a second request to enter into a group with a second playback device that is associated with a second playback queue, entering into the group with the second playback device, associating with the second playback queue, and designating the second playback queue as the active queue of the first playback device. The functions also include receiving a third request to leave the group, and after receiving the third request, de-designating the second playback queue as its active queue.
