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 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, one or more communications are received by a computing device, where each communication is associated with an application on the computing device. Based on the received communications, a set of interactive elements are determined, each interactive element corresponding to a particular received communication. A subset of the interactive elements are determined based on the application associated with the communication corresponding to the interactive element, or the age of the communication corresponding to the interactive element. The subset of interactive elements is displayed.

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 first computing device of a first user of a social-networking system may acquire a tag associated with a second computing device of a second user of the social-networking system, and process the tag for user information comprising a time stamp, a signature, and a social action associated with the social-networking system. The first computing device of a first user may send the information to a computing device of the social-networking system for verification of the user information of the second user. In addition, the first computing device of the first user may receive, in response to the verification, instructions for initiating the social action. The social action as initiated may include a transaction between the at least one node corresponding to the first user and the at least one node corresponding to the second user.

Abstract: In one embodiment, a computing device of a social-networking system may receive from a computing device of a first user of the social-networking system information acquired by the computing device of the first user from a tag associated with a second user of the social-networking system. The tag may encode a time stamp, a signature, and a social action on the social-networking system. The computing device of the social-networking system may verify the signature and, if the signature is verified, then initiate the social action.
