Abstract: In particular embodiments, a temporary user is able to use another's personal computing device in shared mode for a short period of time while experiencing a personalized user interface. An indication is detected that a personal computing device associated with a primary user is to be shared with a temporary user. Access to local personal information associated with the primary user is disabled if it is stored on the personal computing device. Access to remote personal information of the primary user that is accessible from the personal computing device is disabled. A personalized user interface incorporating personal information associated with the temporary user is presented on the personal computing device for the temporary user. Personal information of the primary user is not accessible by the temporary user, and vice versa. When shared mode is to be terminated, all personal information of the temporary user is deleted.

Abstract: In one embodiment, device status information is received from a mobile device of a first user. The device status information may include: information related to power for the device, information related to network connectivity of the device, or a notification mode of the device. Outgoing messages may be identified to be sent to the first user. A value may be computed for each of the outgoing messages. The computed value may be based on an affinity score determined with respect to an originator of the message and the first user. Based on the computed value, at least one of the outgoing messages may be selected for placement into an outgoing message queue. Upon the detection of a triggering condition, the selected messages may be sent to the mobile device. The triggering condition may be based on the device status information and the respective values of the outgoing messages.

Abstract: In one embodiment, a method includes receiving identifier-information from a device of a first user, wherein the identifier-information is associated with a source of an incoming communication; accessing a social graph including nodes and edges, where the nodes include a first node corresponding to the first user, and second nodes corresponding to respective second users; determining whether one or more reporting users, corresponding to respective second nodes within a specified degree of separation from the first node, have flagged the source of the incoming communication as a spam source; and sending, to the first user, a spam-notification object that includes information identifying one or more of the reporting users.

Abstract: In one embodiment, a user places a mobile device (e.g., a smart phone) facing downward on a table. A process running on the mobile device determines an orientation of the mobile device (i.e., a facing downward orientation), and determines that the mobile device has been in the facing downward orientation for over a threshold period of time (e.g., 3 seconds), then the process automatically selects a “Quiet” notification profile, and turn off the mobile device's display, without additional input from the user.

Abstract: In one embodiment, a method includes implementing an ad hoc network protocol comprising transmitting, from a first mobile device, one or more neighbor messages that includes a first user identifier corresponding to a first user of the first mobile device, wherein the first user identifier corresponds to a user account of the first user in a social networking system, receiving, at the first mobile device, one or more second neighbor messages from one or more second mobile devices that include second user identifiers corresponding to respective second users of the one or more second mobile devices, wherein the second user identifiers correspond to respective user accounts of one or more second users in the social networking system, and storing, at the first mobile device, information received in the one or more second neighbor messages for access by one or more applications hosted on the first mobile device.

Abstract: In one embodiment, a computing device determines a communication to be sent to a client computing device. The communication could be a push notification or a keep-alive message from a social-networking system, the client computing device being associated with a user of the social-networking system. The computing device determines that a plurality of network connections already exists between the social-networking system and the client computing device, wherein at least one of the network connections is reserved for, and dedicated exclusively to, sending or receiving notifications or keep-alive messages. The computing device sends the communication to the client computing device using the reserved and dedicated network connection.

Abstract: In one embodiment, a method includes implementing an ad hoc network protocol comprising transmitting, from a first mobile device, one or more neighbor messages that includes a first user identifier corresponding to a first user of the first mobile device, wherein the first user identifier corresponds to a user account of the first user in a social networking system, receiving, at the first mobile device, one or more second neighbor messages from one or more second mobile devices that include second user identifiers corresponding to respective second users of the one or more second mobile devices, wherein the second user identifiers correspond to respective user accounts of one or more second users in the social networking system, and storing, at the first mobile device, information received in the one or more second neighbor messages for access by one or more applications hosted on the first mobile device.

Abstract: In one embodiment, while a mobile electronic device is in a first operation state, it receives sensor data from one or more sensors of the mobile electronic device. The mobile electronic device in a locked state analyzes the sensor data to estimate whether an unlock operation is imminent, and in response to a positive determination, initializes the camera subsystem so that the camera is ready to capture a face as soon as the user directs the camera lens to his or her face. In particular embodiments, the captured image is utilized by a facial recognition algorithm to determine whether the user is authorized to use the mobile device. In particular embodiments, the captured facial recognition image may be leveraged for use on a social network.

Abstract: In one embodiment, a first computing device determines a priority of a communication to be pushed to a second computing device. The priority of the communication is based on a relevance score of the communication with respect to a user of the second computing device. The first computing device sends the communication via a push notification to the second computing device if the priority exceeds a predetermined threshold. The push notification itself comprises the priority of the communication, and the push notification is received by a secondary processor of the second computing device.

Abstract: In one embodiment, a processor may identify information about an entity represented by a first node in a social graph for a social-networking system. The information may comprise a location for the entity and an affinity score for the entity with respect to a user, wherein the user is represented by a second node in the social graph. The processor may then determine a region defined with respect to the location of the entity, wherein the region is defined based in part on the affinity score for the entity, as well as determining that a location of a mobile device associated with the user is within the region. Finally, the processor may cause the mobile device to transition from a sleep state to an active state.
