Techniques to allow for optimizing an image based on an operational context. An operational context including at least one attribute of a client associated with a user of a social networking system is determined. An optimized image is created based on the operational context for provision to the user. The determining the operational context may comprise receiving a client identifier and determining the at least one attribute of the client based on the client identifier. The determining the operational context may comprise receiving location coordinates and determining quality of a data connection based on the location coordinates. The determining the operational context may comprise determining at least one usage trend in at least one geographic locality. The optimized image is provided to an image repository associated with the at least one geographic locality. The operational context may comprise at least one user-defined setting.

Systems and methods for device-dependent image transformations

Techniques to transform network resource requests to zero rated network requests are described. Some embodiments are particularly directed to techniques transform network resource requests on a cellular network to zero rating by replacing the destination of the request with a zero-rated source for the network resource. In one embodiment, for example, an apparatus may comprise a data store and a network access component. The data store may be operative to store a plurality of zero-rating rewrite rules. The network access component may be operative to receive a network request from an application component on the mobile device, the network request for access to a network resource; compare the network resource to the plurality of zero-rating rewrite rules to identify a zero-rating rewrite rule matching the network resource; transform the network request to a zero-rated network request for the network resource using the identified zero-rating rewrite rule; and perform the zero-rated network request. Other embodiments are described and claimed.

In one embodiment, a first computing device receives a write request and data from a second computing device; iteratively attempts to write the data until a copy of the data is successfully written to each and every storage node belonging to a storage volume; and transmits a volume identifier of the storage volume and a data identifier assigned to the data to the second computing device. In one embodiment, a first computing device receives a read request and a volume identifier and a data identifier from a second computing device; accesses a cache to select the storage volume identified by the volume identifier; iteratively attempts to read data identified by the data identifier until a copy of the data is successfully read from a storage node belonging to the selected storage volume; and transmits the copy of the data to the second computing device.

A prediction is calculated to determine whether a content item posted on a social networking system infringes on copyrights or otherwise violates the system's terms of use. The predictions are generated using social signals that are based on social information surrounding the content item, such as the density of connections between the posting user and the viewing users, the profile information of the users, and the geographical separation between the users. The content item is disabled if the prediction indicates a violation and the violation can be verified.
