Abstract: An online system provides video recommendations to a target user of the online system as a supplement to videos provided to the target user that were posted by the user's connections in the online system. The recommended videos are selected from publicly available video content and are likely to be of interest to the target user. The online system has video candidate generators that select video candidates based on a variety of selection criteria. The selected video candidates are filtered to identify inappropriate content or videos that the target user has already viewed for elimination from candidacy. The filtered video candidates are ranked based on weights of features of the video candidates. Based on the ranking, the online system selects videos above a threshold as recommendations to the target user.

Abstract: Dynamically scheduled testing of a software application on one or more devices are disclosed. The system can schedule and execute of one or more test cases associated with a software application.

If there are outstanding untested commits, the system can determine the list of test cases in a test plan that are to be scheduled and executed. For each test in the list of test cases, the system can compute an urgency value. Urgency value can be a function of the untested commits. For example, urgency value can be the number of untested commits associated with each test case. The system can then sort the test cases based on the urgency value and schedule the most “urgent” test case for execution.

Abstract: A social networking system user identifies one or more social networking system users authorized to present content items to the user via the social networking system (“authorized users”). When an additional user requests presentation of a content item to the user, the social networking system determines if the additional user is an authorized user.

Abstract: Exemplary embodiments relate to improvements in the design of a messaging inbox. The inbox may display different units or “modules” for providing a user with quick access to different inbox functionalities that they might not otherwise be aware of (or inclined to use on a regular basis). After a number of recent or unread messages are shown in the inbox's initial interface, the messages end and are replaced with modules. Many different types of functionality may be the subject of the modules (e.g., a module for sharing local content such as photos from a photo album, a People/States module, Top Contacts, New Behavior, Live Videos, Events, Businesses, or Messaging Stickers). Once the available modules have been scrolled through, the interface may revert to more messages, such as less-recent or previously read threads from the original messages. Unread threads may also be collapsed in the top section of the inbox, or included in a module.
