Abstract: An online system receives a request from a user of the online system to generate a content item specifying content (e.g., an image) received from the user and one or more modifications to the appearance of the content to be included in the content item. The online system generates multiple instances of the content item based on the request, in which each instance includes a different set of the specified modifications. Using an identifier that identifies each instance based on the set of modifications to the appearance of the included content (e.g., using an image fingerprint), the online system tracks a performance metric associated with each instance. By comparing the performance metrics associated with the instances, the online system identifies one or more modifications responsible for one or more differences between the performance metrics and predicts an effect on the performance metrics associated with content item instances including the identified modifications.

Abstract: A social networking system displays raw stories about a user's friends' actions in a news ticker as those actions occur. The social networking system is monitored for actions associated with users connected with the target user. The social networking system may be continually monitored such that actions are identified in real-time as they are performed. The news ticker is updated such that stories including the identified actions and the associated connected users are displayed within a news ticker interface. The news ticker interface may be a dedicated portion of the social networking system interface, for example in a column next to a newsfeed. The news ticker interface may be updated in real time as actions associated with connected users are performed. The target user may select a displayed story in the news ticker, and additional information related to the selected story may be displayed, for instance in a separate interface.

The social graph includes nodes and edges connecting the nodes. The nodes include user nodes that are each associated with a particular user of the social-networking system. The one or more computer systems of the social-networking system determine, using the social content and the available media content, a plurality of social coefficients for the user, determine, based on the determined social coefficients, recommended media content for the user, and provide the recommended media content for display in a programming guide on a display device.

Abstract: In particular embodiments, a computing device receives from each of one or more contact-information sources a set of contact information associated with a user of a social-networking system. The set of contact information includes one or more instances of contact information in one or more categories of contact information. The computing device automatically selects, in each of the categories of contact information, one of the instances of contact information from the sets of contact information as a default for the category of contact information for a second user of the social-networking system.

Abstract: A social networking system provides relevant content objects at the request of social networking system users. Relevance scores are determined for content objects by matching user location, user interests, and other social information to the content, location, and timing associated with content objects. A ranked list of content objects can be provided to the user, where the content objects are relevant to them based on their interests, location, and other social information. The system provides a user interface that displays a map containing pins, where each pin represents a content object in actionable proximity to a user. The content objects selected to be presented as pins to the user are those content objects with sufficiently high relevance scores. Multiple pins for a nearby area can be clustered. The user can switch between zoom levels for the map, thereby showing pins at varying distances from the user's current location.

Abstract: In one embodiment, an uploaded multimedia object comprising a photo image or video is subjected to computer vision algorithms to detect and isolate objects within the multimedia object, and the isolated object is searched against a photographic location database containing images of a plurality of locations. Upon detecting a matching object, the location information associated with the photograph in the database containing the matching object may be leveraged to automatically check the user in to the associated location.

Abstract: In one embodiment, a social networking system receives a selection of a user in a first user interface, accesses one or more data stores for the user's user profile information, constructs a frame containing the user's user profile information, and displays the frame overlaying the first user interface.

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, a method includes determining available media content from one or more content sources and providing at least a portion of the available media content for display in a programming guide on a display device of a user. The programming guide includes a plurality of entries each associated with one of the available media content. The method further includes determining that an update action button should be displayed on the display device, providing the update action button for display on the display device when it is determined that the update action button should be displayed, and updating the programming guide in response to a user selection of the update action button. The update action button is operable to cause the social-networking system to update the programming guide.

Abstract: In particular embodiments, a social networking system queries a social graph of the social-networking system for social content associated with video content provided to one or more users of the social-networking system and accesses privacy settings associated with each of the one or more users. The privacy settings indicate whether a particular user has authorized the social-networking system to share social content associated with the particular user with one or more third parties. The social networking system provides the social content associated with video content provided to the one or more users to a particular third party if the privacy settings of the one or more users indicate that the one or more users have authorized the social-networking system to share the social content with one or more third parties.

Abstract: In one embodiment, a method includes collecting, by one or more computing devices, multiple information items of multiple types relevant to a user, where the information items are collected from a social-networking system, and the user is a member of the social-networking system.
