Abstract: Method of dynamically assigning storage locations starts with the processor updating first user's home location data. Processor selects communication session between first user and second user and determines second user's home location data. Processor determines a session location data that indicates current storage location that stores data of communication session received from first and second client devices. Processor identifies available data storage locations based on first user and second user's home location data and determines whether to update the session location data based on an average of a distance over network fiber using the first user and second user's home locations, current storage location, and available storage locations. In response to determining to update the session location data, processor updates session location data to indicate one of the available storage locations, and causes transfer of data of communication session to one of the available storage locations.

Abstract: Systems and methods are provided for data synchronization for client application generated data. Content may be generated by a client application executed by a creator client device and sent to a server system that may distribute the content to one or more additional client devices of recipients of the content. The server system can push content to the recipient client devices without receiving a request for the content from the recipient client devices. The content generated by the creator client device may be stored by each of the creator client device, by the server system, and by the one or more recipient client devices. The server system may also generate version data related to respective versions of content that may be consumed by a client application. The version data may be used by client devices to determine versions of content that may be missing from the client devices.

Abstract: Method of dynamically assigning storage locations starts with the processor receiving a signal from a first client device associated with a first user. Processor stores a current location of the first client device in a historical database and determines whether a home location data associated with the first user matches the current location. In response to determining that the home location data associated with the first user does not match the current location, processor determines whether the first user has been associated with the current location at a greater frequency than the home location data based on the historical database. In response to determining that the first user has been associated with the current location at a greater frequency, processor updates the home location data associated with the first user to the current location. Other embodiments are described.

Abstract: Disclosed are systems, methods, and computer-readable storage media for displaying widgets. In some aspects, criteria for ranking widgets may be dynamically evaluated based on conditions associated with each widget. In some aspects, the conditions may consider a time or location of an event a social network user is scheduled to attend, and a relation to that time and location to a current time and/or current user location. Evaluation of the conditions may contribute to the determination of weights for each of the respective widgets, with the ranking based on the weights. Widgets with the highest rank may be invoked, and selectively displayed on an electronic display. Multiple possible parameter values for the displayed widgets may also be dynamically ranked and selected values applied when invoking the widget.
