Abstract: A system is provided that is designed to smooth and reduce the transition time of a live stream while switching to different bitrate transcode profiles. This accomplishment is achieved by avoiding pre buffer time using parallel transcode sessions and enabling a fast response to network congestion, as desired bitrate chunks/segments are readily available. The client, for example the HLS client, is not aware of switching the bitrate and is not taxed with any demands, as only the HLS server needs to manage synchronization of any pre-transcoded content and continue with further transcoding of the content.

Abstract: A method for receiving a first signal from a first client device, the first signal indicative of a first user activity is provided. The method includes receiving a second signal from a client device, and storing the first signal and the second signal in an activity history log associated with the first user. The method includes determining, by a server, a presence status of the first user, configuring a presence indicator for the first user based on the presence status, and receiving, from a second user, a request for the presence indicator for the first user. The method includes validating the request from the second user and providing the presence indicator for the first user to the second user. A system and a non-transitory, computer readable medium storing instructions to perform the above method are also provided.

Abstract: Methods, apparatus, and computer-accessible storage media for providing a volume-based block storage service and application programming interfaces (APIs) to the service. A block storage service and block storage service APIs may allow processes (applications or appliances) on the service client network to leverage remote, volume-based block storage provided by the service provider. The APIs may provide a standard interface to volume-based block storage operations on a remote data store. The service provider, the service clients, and/or third parties may develop various applications and/or appliances that may, for example, be instantiated in service clients' local networks and that leverage the block storage service via the APIs to create and manage volumes and snapshots on the remote data store and to upload and download data from the volumes and snapshots on the remote data store.

Abstract: A computer system allows two devices operated by two users from a plurality of trusted users to establish a direct peer to peer wireless connection based on a social network connection. An online system uses social network connection information to determine trusted users for each of the client devices, and monitors the geographic locations of the client devices. Responsive to determining that the client devices are within a predetermined distance from each other and are trusted users for each other, the online system transmits connection information to the client devices, prompting the client devices to establish a direct peer to peer wireless connection through which content can be transmitted.

Abstract: Generating an automated agent enabled to engage in a multi-turn discussion with a user in response to a received request. For example, the automated agent is operative to provide a response on behalf of an agent owner. A knowledge database is generated based on the agent owner's context (e.g., email conversations, calendar data, organizational chart, document database). A request for information is received and analyzed for understanding the request and for gauging a level of frustration of the requesting user. An urgency level of the request is determined based at least in part on the level of frustration of the requesting user. A query of the knowledge database is made for determining a response to the request, wherein the determined response is based at least in part on the urgency level of the request. A response is generated and provided to the requesting user.

Abstract: A provider network determines which servers to use to host a group of virtual machines for a customer. A placement manager within the provider network employs a placement technique which prioritizes spreading virtual machines for the customer across different “subzones.” A subzone is a logical division of a provider network's hardware and/or software denoting risk boundaries. By placing virtual machines in separate subzones, the customer's virtual machines and thus the task collectively performed by the virtual machines are less impacted by a failure within one of the subzones.

Abstract: A dynamically scalable computing framework used in support of on-line services is disclosed. A network is formed from computing nodes communicatively coupled with communication hubs in a mesh configuration. A load balancing module executing on a computing node monitors processing relating to a plurality of data objects. When a processing threshold is reached, the computing node dynamically reallocates processing of a subset of data objects sharing the same property to a second computing node. Processing nodes in the network receive subscription rules defining characteristics of data objects suitable for copying to another computing node in the network. In response to receiving subscription rules, processing nodes evaluate the rules against data objects on the particular processing node to identifying data objects that should be copied to the other processing nodes corresponding to the received subscription rules.

Abstract: A storage controller processes electronic messages by partitioning a storage device into logical disks and designating a logical disk as unavailable based on its storage capacity being fully used. A time is assigned to each logical disk that is available for writing, and an estimated deletion time is determined for an electronic message. The electronic message is stored in a logical disk that is identified by comparing the assigned times of the logical disks to the estimated deletion time of the electronic message. The electronic message may be deleted based on the detection of a triggering event. If a deletion of a message results in an unavailable logical disk having more than a threshold amount of unused storage capacity, then each of the electronic messages stored in the unavailable logical disk may be copied to a logical disk available for writing and the unavailable designation may be removed from the logical disk.

Abstract: In time and sentiment based messaging, a server obtains information for a set of messages from online social networks related to a specified object. The information includes at least a user identifier associated with each message, a time of each message, and content of each message. For each unique identifier, the server establishes an initial message from the set of messages related to the specified object, analyzes each message in the set of messages to determine a sentiment of each message, and builds a sentiment line time for each unique user identifier. The server then builds a time-based sentiment model related to the specified object by overlapping the sentiment time lines for each unique user identifier according to the initial message for each unique user identifier. A targeted message to a set of one or more users may then be generated using the time-based sentiment model.
