The calculated interest value is based at least in part on the identified categories of interest to the user. The method also includes providing the recommendations for transmission to the client device. The recommendations include one or more of the identified objects.

Abstract: Collecting contact information for a plurality of contact entities from various sources and ranking the contact information based at least on the sources. The ranking of the contact information is determined based on the reliability of the sources. The ranked contact information is shared with users subject to privacy settings. The privacy setting allows the users or the contact entity to share certain contact information with others while keeping certain contact information privately or sharing the contact information with a limited number of users. After a change in the contact information from a reliable source is detected, the change may be propagated to other sources or client devices of the users.

In some implementations, a pinch gesture may cause an application to close.

Abstract: In one embodiment, a method includes receiving visual information captured by a recording device associated with a first user, the visual information capturing aspects of a physical environment of the recording device; based on the visual information, identifying a second user within the physical environment; in response to identifying the second user, retrieving information about a particular action the second user has performed on the social-networking system with respect to a concept or third user; and in response to retrieving the information about the particular action, sending the information about the particular action to the first user while the first user and the second user are both within the physical environment.

Abstract: A social networking system provides relevant third-party content objects to users by matching user location, interests, and other social information with the content, location, and timing associated with the content objects. Content objects are provided based on relevance scores specific to a user. Relevance scores may be calculated based on the user's previous interactions with content object notifications, or based on interests that are common between the user and his or her connections in the social network. Context search is also provided for a user, wherein a list of search of results is ranked according to the relevance score of content object associated with the search results. Notifications may also be priced and distributed to users based on their relevance. In this way, the system can provide notifications that are relevant to user's interests and current circumstances, increasing the likelihood that they will find content objects of interest.

Abstract: Using pinch gestures to navigate user interface layers of an application. In particular embodiments, a pinch gesture may cause an application program to close a currently running user interface layer of the application and navigate to another user-interface layer of the application. In some implementations, a pinch gesture may cause an application to close.

Abstract: In one embodiment, a method includes receiving one or more audio/visual recordings from a user, the audio/visual recordings continuously capturing audio/visual information around the user, the audio/visual recordings being made by a client computing device of the user automatically and without manual user input and with one or more sensors of the client computing device; processing the audio/visual recordings to extract one or more audio/visual segments, each audio/visual segment covering a specific time period or relating to a specific event in the user's life; and posting the audio/visual segments to one or more points, respectively, along a timeline corresponding to the user's life.

Abstract: In one embodiment, a search request is received from a first user, the request including the first user's location. One or more search results and their corresponding geographic locations located within a threshold geographic distance of the first user's location are determined in response to the search request. Each of the search results is ranked based on a recency of one or more rating values associated with the search result, the one or more rating values being associated with one or more second users, respectively. Ranked search results are sent for presentation to the first user.

Abstract: A computer-implemented user interface method includes displaying on a touch screen a portion of a large scale graphical space that is at least multiples larger than the device display, receiving from a user of the device an input to pan within the graphical space, automatically generating a pop up graphical panning control in response to receiving the user input, and receiving a user input to the panning control and providing panning in the graphical space, wherein movement of the panning control in a single selection is able to pan the display across a substantial portion of the large scale graphical space.
