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: Techniques to allow for ease of navigation within a photo browsing interface of a social networking system. In one embodiment, a designation of a first image for sharing is received from within at least one of a single-image view and a camera view. Based on the designation, the first image is added to a communication. The designation may be based on a user selection of an option provided by an interface of a mobile device. The first image may be received from within a social networking application or from within a dedicated camera application. In another embodiment, the privacy level of the communication and the designated images is based on the privacy setting of a user. The communication and the designated images may contain tag data identifying one or more people on a social networking system. In an alternative embodiment, the privacy level of the communication and designated images is adjusted according to the one or more people identified in the tag data.

Abstract: A method of operating a content distribution system with a server controlled routing mechanism is disclosed. The method includes: collecting prefix entries from an autonomous system; receiving a content request to send a particular digital content to a prefix; generating, at a host server, an opaque label based on the autonomous system for an Internet protocol (IP) packet of the digital content when the prefix is listed in the prefix entries collected from the autonomous systems; and forwarding the IP packet out of an egress interface of a network equipment, the egress interface associated with the opaque label.

Abstract: An analysis system analyzes known user affinities to identify particular objects that serve as useful predictors of whether a given user will have an affinity for a given topic, even if the user has not previously expressly specified an affinity for that topic. Specifically, both the topic group of users associated with a given topic and the category group of users associated with the topic's more general category are identified. For each of a set of objects, degrees of divergence between the topic group and the category group are evaluated for a criterion evaluated with respect to the object. A topic profile is created based on objects for which there is a high degree of divergence.
