    Abstract: A system and methods are provided for aggregating communication connections. Multiple users connect to a system (e.g., a web-based system) that hosts an application or service for exchanging communications. Users who exchange communications among themselves may be considered “associates.” When one user who is on-line with the application sends a communication through the system for an associate, the system determines whether the associate is on-line or off-line. If the associate is off-line, the system crafts and sends toward the associate a notification regarding the communication, including an address of the communication server to which the one user is connected. When the associate's device receives the notification, the application may attempt to connect to the specified address. In this way associated users' connections will aggregate or gravitate toward the same communication server, thereby eliminating the latency and cost of exchanging users' communications between multiple communication servers.

    Abstract: Techniques to dynamically engage a reduced-color mode for streaming video encoding are generally described. For example, in one embodiments, an apparatus may include an encoding configuration component operative to receive network performance information for a video stream at a sending device, the video stream using a first number of variable bits for color encoding; and assign a reduced-color mode to a media component based on the network performance information, the media component operative to generate the video stream in the reduced-color mode, wherein the reduced-color mode uses a second number of variable bits for color encoding, the second number less than the first number, and a network component operative to send the video stream from the sending device to a receiving device using the reduced-color mode. Other embodiments are described and claimed.

    Abstract: Exemplary embodiments relate to techniques for sending ephemeral content messages via a communications service. An interface may be presented to allow a user to initially access ephemeral content functionality and select content for inclusion in the ephemeral content message. The interface may present a streamlined set of use cases without regard to the manner in which the content was initially captured. Different types of content may be used as ephemeral content, including images, videos, weather reports, news stories, text, audio recordings, location tags, etc. The ephemeral content may be sent through the communications service as an end-to-end encrypted message. When a user replies to an ephemeral content message, the reply may trigger a one-to-one conversation between the originating user and the replying user. Alternatively, an ephemeral content message may be initially sent to a selected group, and replies may be sent back to the entire group.
