Abstract: A method and system for delivering a presentation created using a presentation application program are disclosed. One method includes initiating, from a presentation computing system, display of a presentation to one or more remote computing devices. The method also includes creating an initial display package based on the presentation that includes metadata describing the presentation and an image representative of the presentation, and uploading the initial display package to a presentation server. The method includes, after uploading the initial display package, creating an initial set of presentation slides from the presentation, and uploading the initial set of presentation slides to the presentation server. The method further includes, after uploading the initial set of presentation slides, uploading at least a remaining portion of the presentation to the presentation server for display at one or more of the remote computing devices.

Abstract: Methods for bridging computers functioning as Publish/Subscribe brokers are provided to build a distributed cluster for scalability by enabling publishers to connect to one broker and subscribers to that publisher to connect to a different broker. In one aspect, a method includes listening to an internal bridge port on one broker for receiving bridge connections from other brokers in the cluster, and in parallel, connecting to the internal bridge ports of each of the other brokers in the cluster, waiting for all such incoming and outgoing bridge connections to be completed, and then opening up the external port for serving actual clients. The method also includes creating separate bridges for each direction of traffic to make the broker code completely symmetric and also supporting the creation of an arbitrary number of bridge connections between each pair of brokers for each direction to reduce latency.

Abstract: Methods for returning a computing system to a previous state are provided. In one aspect, a method includes loading a second system state of a second operating system partition, and receiving a request to return to a first system state of a first operating system partition while operating in a second system state of the second operating system partition. The method also includes loading the first system state of the first operating system partition. Systems and machine-readable media are also provided.

Abstract: Methods for bridging computers functioning as Publish/Subscribe brokers (e.g. MQTT brokers) are provided as a means to build a distributed cluster for scalability by enabling publishers to connect to one broker and subscribers to that publisher to connect to a different broker. In one aspect, a method includes listening to an internal bridge port on one broker for receiving bridge connections from other brokers in the cluster, and in parallel, connecting to the internal bridge ports of each of the other brokers in the cluster, waiting for all such incoming and outgoing bridge connections to be completed, and then opening up the external port for serving actual clients. The method also includes monitoring that the bridge connection is alive and healthy throughout the operation of the broker and upon detection of connection failure, storing the messages in a persistent store and replaying them on the bridge connection once it is restored.

Abstract: Methods for scheduling data download requests for a device are provided. In one aspect, a method includes assigning to a device a first wait period of a random length below a first pre-determined maximum value, and receiving a notification that data is available for download to the device. The method also includes determining whether an amount of time elapsed since the data was made available for download to the device exceeds the first wait period, and when the determination indicates that the amount of time elapsed since the data was made available for download exceeds the first wait period, downloading the data available for the device. Systems and machine-readable media are also provided.

Abstract: A client device selectively establishes connections between selected client communication components and corresponding server communication components. The client device receives data from the corresponding server communication components via the connections between the selected client communication components and the server communication components. The data received via different ones of the connections is associated with a different content stream of a teleconference. During the teleconference, a given connection is suspended. When the given connection is suspended, the client computing device continues to receive data via connections other than the given connection.

Abstract: Presentations during an online conference are captured for subsequent playback. An instance of a presentation viewer is deployed to capture the presentation. Annotations and timing data are captured separately. The presentation with the annotations is recorded through a video encoding codec in a desired format, while timing and similar data is stored as metadata. Multiple presentations may be recorded separately to conserve resources. The recordation and the metadata can be subsequently played back to a requesting user.
