In one embodiment, a method includes receiving information associated with an image. Information regarding a viewing context for displaying the image may be received. The viewing context may comprise one or more factors, including, by way of example and not limitation: technical specifications for a display device, a physical environment of the display device, a state of the display device, and user preferences. Customization of the image may comprise modifying any aspect of the image, over the whole image, or just a portion of the image, such as, by way of example and not limitation: luminance, chrominance, resolution, etc. The image is customized with respect to the viewing context, and then the customized image is provided for display.

A social networking system determines common location information included in a set of posts between a set of users. Using the determined common location information, the social networking system generates a message interface for grouping a set of messages into a conversation thread. For example, the messages may be grouped into a conversation thread based on common location information in the messages and being associated with participants sharing a social relationship. When a group conversation is created, the social networking system presents a message interface containing the conversation thread to one or more participants of the thread. The social networking system adds the set of messages to the conversation thread based on social information about the social relationships among the participants of the conversation thread. The social networking system then presents the message interface for display to one or more of the participants.

In particular embodiments, the newsfeed is rendered to a particular user using the locally stored copy of the resource, instead of pulling it back from the server-side. Thus, a user may see his or her content even before it is completely uploaded to the social networking system. In particular embodiments, the user may interact with the content, for example, by adding comments, captions, “likes”, etc. to the content even before it has been completely uploaded to the social networking system. In this manner, the user is provided an increased feeling of responsiveness that is independent of the current wireless link condition.

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.

In one embodiment, a social networking system maintains a moving average of the number of connection problems, including socket timeouts and failed uploads, per client in a geographic area to determine whether the wireless data network serving the geographic area is overloaded. In response to detecting a network overload, the social networking system may transmit an instruction to the clients in the particular geographic area to enter one of a plurality of traffic throttling modes. In particular embodiments, the social networking system maintains a historical log of network overload conditions, and uses the historical log to generate an estimate of the wireless network capacity serving a geographic area. Thus, the social networking system may preemptively transmit instructions to clients to enter a bandwidth-conservation mode when the estimated traffic demand exceeds the estimated capacity for a particular geographic region.

Client devices periodically capture ambient audio waveforms, generate waveform fingerprints, and upload the fingerprints to a server for analysis. The server compares the waveforms to a database of stored waveform fingerprints, and upon finding a match, pushes content or other information to the client device. The fingerprints in the database may be uploaded by other users, and compared to the received client waveform fingerprint based on common location or other social factors. Thus a client's location may be enhanced if the location of users whose fingerprints match the client's is known. In particular embodiments, the server may instruct clients whose fingerprints partially match to capture waveform data at a particular time and duration for further analysis and increased match confidence.

Methods, apparatuses and systems directed to sponsored story generation from an photo upload in an organic activity stream in a social networking site. A social networking system may apply computer image algorithms to detect image objects in user-uploaded images and videos, and promote them as sponsored stories.

In particular embodiments, one or more images associated with a primary user are received. The image(s) may comprise single images, a series of related images, or video frames. In each image, one or more faces may be detected and/or tracked. For each face, one or more candidates are selected who may be identified with the face. Each candidate may be connected to the primary user within a social network. A candidate score for each candidate associated with a detected face. Finally, the winning candidate is determined, and a suggestion to identify the detected face as being the winning candidate is presented. Some embodiments may operate upon video clips as the video is captured by a mobile device. Some embodiments may operate upon series of images as they are uploaded to or viewed on a website.
