Abstract: In one embodiment, a method includes accessing for a user one or more electronic notifications that include information about a social network. The social network includes a plurality of nodes connected by a plurality of edges, with at least one node corresponding to the user. The method further includes determining, for each of the electronic notifications, a score that estimates whether a user interaction with the social network will result if the electronic notification is provided to the user. The method further includes determining, based at least in part on the determined scores, an action to take with respect to the electronic notifications.

Abstract: Systems, methods, and non-transitory computer-readable media receive a source video having a source file size. A bit rate at which to encode the source video is determined. The source video is encoded at the determined bit rate to produce an encoded video having a file size less than the source file size. A video quality metric for the encoded video is determined. Whether or not the video quality metric for the encoded video is within an allowable deviation from a target quality metric is determined. The source video is encoded at another determined bit rate when the video quality metric for the encoded video is outside the allowable deviation from the target quality metric. Determining the bit rate and encoding the source video at the determined bit rate can repeat iteratively until the video quality metric for the encoded video is within the allowable deviation from the target quality metric.

Abstract: In one embodiment, a method includes one or more computing devices ranking multiple users of a social-networking system based on one or more criteria associated with a spotlight content item, wherein the spotlight content item is associated with a node in a social graph associated with the social-networking system, and wherein at least one of the criteria is based on social-networking information for each of the user, verifying the ranked users, wherein the verifying comprises confirming or eliminating each of the ranked users based on recent interactions by the ranked users with social-networking information corresponding to the node associated with the spotlight content item, and sending a notification about the spotlight content item to each of the confirmed users in accordance with a batching protocol, wherein the batching protocol is determined based at least in part on rankings for each of the confirmed users.

Abstract: Systems, methods, and non-transitory computer-readable media receive source video content, encode the source video content by a first encoding process to produce compressed video content, apply edge detection to the compressed video content to produce first edge-detected video content, and encode the first edge-detected video content by a second encoding process to produce first encoded video content. The systems, methods, and non-transitory computer-readable media may further equalize the source video content by an equalization algorithm to produce equalized video content, apply edge detection to the equalized video content to produce second edge-detected video content, and encode the second edge-detected video content by the second encoding process to produce second encoded video content. The systems, methods, and non-transitory computer-readable media may compare the first encoded video content and the second encoded video content, and adjust the first encoding process based on the comparison.
