Abstract: In one embodiment, a method includes providing for presentation to a user a number of content objects. At least one of the presented content objects is socially relevant to the user. wherein at least one of presented content objects is socially irrelevant to the user. The presented content objects are socially relevant or socially irrelevant to the user based on whether in a social graph a node corresponding to the user is connected by an edge to a node associated with the content object. The edge represents a social relationship between the content object and the user. The method also includes receiving an input indicating a selection of a number of the presented content objects by the user; and authenticating the user based on a determination of whether the selected content objects are socially irrelevant to the user.

Abstract: In one embodiment, a method includes determining one or more applications on one or more first client computing devices of a first user of a social-networking system; determining one or more second users of the social-networking system that are connected to the first user within the social-networking system; determining one or more applications on one or more second client computing devices of the second users; comparing the applications on the first client computing devices with the applications on the second client computing devices; determining one or more application recommendations for the first user based at least in part on the comparison; and sending the application recommendations to the first user.

Abstract: In one embodiment, user information for a user of a social-networking system is retrieved. Device information is determined for a device associated with the user. Based on the device information or the user information, content associated with the user is retrieved. Using the retrieved content, a content board is composed for use in a cover feed displayed on the device The content board may comprise a background image. Finally, the content board is sent to the device. In one embodiment, updated information for content associated with the user is retrieved. The updated information may be associated with content that was included in a previously-provided content board. Using the updated information, an update to the previously-provided content boards is composed. Finally, the updates may be sent to the previously-provided content boards to the device.

Abstract: In one embodiment, a method includes determining whether a user of the mobile computing device is currently actively using an application on the mobile computing device; and if the user is not currently actively using an application on the mobile computing device, then automatically and without user input providing for display to the user on the mobile computing device a user interface (UI) including a number of interactive elements that each correspond to one of a number of social-networking functionalities provided at least in part by a social-networking system remote from the mobile computing device.

Abstract: In one embodiment, a method includes displaying one of a number of graphical user interfaces (GUIs) of one or more applications as a card on top of a card stack. One or more of the cards in the card stack corresponds to a GUI of a home screen of the computing device. Each of one or more of the cards in the card stack corresponds to one of the GUIs of an application. The application controls presentation of their GUIs as cards in the card stack. The method also includes receiving user input to display another one of the GUIs as the card on top of the card stack; and, in response to the user input, displaying the other one of the GUIs as the card on top of the card stack.

Abstract: In one embodiment, a method includes extracting, by a computing device, information from an electronic message, where the electronic message has been communicated to or from a user of a social-networking system, cross-referencing, by the computing device, the extracted information with social-networking information associated with one or more nodes or edges of the social-networking system, and determining, by the computing device, an action for execution by the social-networking system based on the cross-referencing.

Abstract: In particular embodiments, one or more notifications are presented on a screen of a personal computing device while the personal computing device is in a locked state. Entry of one or more user responses may be detected on the personal computing device while still in the locked state. Each user response may be associated with at least one notification. An authorization event associated with the personal computing device may be detected, thereby unlocking the personal computing device. The one or more user responses on the personal computing device may then be presented to the user for confirmation. Once user confirmation is received, confirmed user responses may then be published.

Abstract: In one embodiment, a method includes receiving from a mobile device of a user configuration data of the mobile device. The configuration data identifies one or more characteristics of the mobile device.

Abstract: A communication icon represents a shared connection allowing members of an online group to interact with each other and participate in different activities together. The icon through which the group interacts resides on each group member's desktop and has many attributes including click activation modes and drag and drop functionality. The icon provides each group member with a representation of the group's shared relationship. Any group member can change the group icon and have that change propagated to the computers of the other members of the group. The icon can be activated for both non-verbal and verbal communications as well as activity sharing. Online members of the group are kept apprised of the group's status and activities via a displayed status bar.

Abstract: A novel application and user interface for facilitating group interactions over a network integrates messaging, file sharing, media playing, journaling, profiles, and gaming into a cohesive environment. The groups facilitated by the invention are persistent and mobile in that a user does not have to recollect and reconfigure the group each time he or she wants to interact with the group online and, while online, the group may be taken from one activity to another without having to disband and reconnect at the second activity. The application is modular so as to be extensible to include other activities and functionalities. In an embodiment, the group interaction application utilizes a peer-to-peer network environment to facilitate network communications between group members.
