Abstract: A method of executing an A/B testing service comprises deploying an instance of the A/B testing service between a client device and an A/B testing server and receiving by the A/B testing service from the A/B testing server a software development kit (SDK) key for a client device, the SDK key indicating an A/B testing environment to be associated with the instance. The method further comprises, in response to receiving the SDK key: storing data associated with the A/B testing environment in memory of the client device; providing a HyperText Transfer Protocol (HTTP) application programming interface (API) associated with the instance of the A/B testing service to one or more applications associated with the A/B testing environment; and executing, by a processing device, commands between the client device and the one or more applications on behalf of the A/B testing environment.

Abstract: A method includes receiving, from a computing device, a request for content hosted by a content provider and determining one or more experiment variations for the requested content that the computing device is assigned to based, at least in part, on the request. The method further includes generating, by a processing device, a hash value of the one or more experiment variations and transmitting the hash value to the computing device and to a caching server.

Abstract: A sensor has a plurality of transmitting antennas and a plurality of receiving antennas. The plurality of transmitting antennas each transmit millimeter wave signals. An object or body part's interaction with and reflection of millimeter wave signals are determined by the signals received by the receiving antennas. Signals having different frequencies are used to provide resolution and positioning of an object or body part in the space proximate to and/or relative to the sensor. Interpretation of millimeter wave radio signals reflected by objects in the environment, by the sensor, can then be used to generate outputs to devices.

Abstract: Systems, methods, and non-transitory computer-readable media can provide one or more options to adjust, in a virtual three-dimensional space, an image in an initial perspective. At least a first command, provided based on the one or more options, to adjust the image from the initial perspective into an adjusted perspective can be detected. The image can be adjusted, based on at least the first command, into the adjusted perspective in the virtual three-dimensional space to produce an adjusted image. A second command to modify a viewable area of the adjusted image can be detected. At least a portion of the adjusted image can be automatically fitted, when the second command has ceased, within a specified display area while one or more empty regions can be minimized in the specified display area.

Abstract: A social networking system provides a user with a feed of content items associated with other users connected to the user via the social networking system. Additionally, the social networking system identifies additional content items for presentation to the user and generates groups of additional content items so each group includes content items having a characteristic associated with the group. A scoring function is applied to each group to determine an expected amount of user interaction with content items in the group. Based on the expected amounts of user interaction, a featured content item is selected from each group. When a group of the additional content items is presented, the featured content item is visually distinguished from other content items in the group.

Abstract: Particular embodiments provide a plurality of image elements arranged in a display layout. When user input selecting one of the image elements is received, a first animation sequence for an information panel associated with the selected image element may be displayed, wherein the information panel swings down from a bottom edge of the selected image element. As the information swings down, the selected image element may also be enlarged until it reaches a pre-determined size with respect to a display of the computing device. In response to receiving user input dismissing the selected image element, another animation sequence may shrink the selected image element while showing the information panel swinging up and eventually disappearing.

Abstract: A social networking system provides a user with a feed of content items associated with other users connected to the user via the social networking system. Additionally, the social networking system identifies additional content items having various characteristics to the user. If the user selects an additional content item, further content items having one or more characteristics matching the selected additional content item are identified and presented to the user along with the additional content item. For example, a size of the selected additional content item is increased and the further content items are presented in a smaller size proximate to the selected additional content item.

Abstract: Particular embodiments provide a plurality of image elements arranged in a display layout. First user input selecting one of the image elements may be received, wherein the selected image element is at a particular position in the display layout. In response to the first user input, a first animation sequence to enlarge the selected image element until the selected image element reaches a pre-determined size with respect to a display of the computing device may be displayed. Second user input dismissing the selected image element may be received. In response to the second user input, a second animation sequence to shrink the selected image element may be displayed. Finally, the display layout may be provided for presentation, wherein the selected image element is shown within the display layout in the particular position.
