Abstract: An online system provides a continuous feed of content items to a client device. The online system maintains an ordered set of ranked content items for sending to the client device. The online system receives requests from the client device for content items and selects a subset from an ordered set of ranked content items in response to each request. The number of content items in the subset may be based on factors such as the network connection strength of the client device. The client device re-ranks content items received from the online system based on information received during a given session. The session information may indicate the types of content items viewed during the given session, or the speed at which the user is viewing content items during the given session.

Abstract: Techniques for mobile device personalization are described. In an embodiment, user credentials for an online service are received at a mobile device kiosk.

The user data may be transferred between the mobile device kiosk and a wireless transmitter embedded on a printed circuit board (PCB) of the mobile device. Further, the user data may be transferred to the mobile device without powering on the mobile device. Once the data transfer is complete, the mobile device may be provided to a user.

Abstract: A direction-switchable transponder of a high speed communications network, e.g., an fiber optic data communications network, is capable of dynamically reversing the data traffic flow of its various communications channels in response to a signal. The signal can specify a number of channels, a channel map, or a required bandwidth. The direction-switchable transponder can receive a signal relating to network bandwidth requirements; select, based on the received signal, one or more fiber optic channels for reversing direction of flow of network traffic; and dynamically and automatically reconfigure the selected fiber optic signal to reverse direction of flow of network traffic. By responding to asymmetric bandwidth requirements, the direction-switchable transponder uses high speed communications network lines more efficiently.

Abstract: Exemplary methods, apparatuses, and systems provide a user of a social network system access to a game over a network from a user device.

The social network system sends a list of matched players to the user device for selection by the user, and sends an invitation to one or more of the players selected by the user to enable the user to play the game over the network with the one or more players.

Abstract: Navigating on a display includes tracking motion of an input tool on a display, comparing a motion of the input tool to a threshold, and changing a position of the visible portion of a page of information on the display if the input tool motion exceeds the threshold. The position of the visible portion of the page of information on the display is constrained if the motion does not exceed the threshold.

Abstract: In one embodiment, a computing device may receive a structured document that includes a list of markers and place-marker elements corresponding to data objects of the structured document. Each marker in the list of markers corresponds to a subset of the place-marker elements. Without loading all the data objects, the device may determine a size of a scroll bar for a GUI based on size information associated with the place-marker elements. In response to detecting a scroll or resize event, an event handler may identify at least one marker in the list of markers whose corresponding subset of place-maker elements is within a portion of the structured document that is viewable through the graphical user interface. The handler may load the data objects corresponding to the subset of the place-marker elements corresponding to the identified marker. The identified marker may then be removed from the list of markers.

Abstract: A method and image processing system determine parameters of a camera. According to the method, an image of a surrounding area is captured by the camera, and camera parameters are initially determined. Furthermore, a three-dimensional geometric description of visual features of the surrounding area is provided. A feature detector is used on the captured image in order to extract visual features. The initially determined camera parameters are applied to the three-dimensional geometric description of the visual features of the surrounding area in order to display said visual features on a feature image. A quantity of the visual features extracted from the image is compared with a quantity of the visual features in the feature image to determine a degree of concordance between the two quantities. The camera parameters are changed repeatedly to determine additional feature images for which the degree of concordance is determined until said degree exceeds a threshold.

The qualitative analysis may determine a category of interaction for the impression, the score may be based at least in part on the category of interaction, and the category of interaction may include user input related to the comment, such as a reply to the comment.

Abstract: A canvas generation system generates a canvas view of a scene based on a set of original camera views depicting the scene, for example to recreate a scene in virtual reality. Canvas views can be generated based on a set of synthetic views generated from a set of original camera views. Synthetic views can be generated, for example, by shifting and blending relevant original camera views based on an optical flow across multiple original camera views. An optical flow can be generated using an iterative method which individually optimizes the optical flow vector for each pixel of a camera view and propagates changes in the optical flow to neighboring optical flow vectors.

Abstract: Some embodiments include a stream consolidation engine in a social networking system. The stream consolidation engine can receive two or more input data streams (e.g., an activity record data stream and an application service output stream) from the social networking system. The stream consolidation engine can merge an activity record from the activity record data stream with at least a data record from the input data streams (e.g., from the activity record data stream or the application service output stream) to create a conglomerate data record. The stream consolidation engine can supplement the conglomerate data record with asynchronous information from a data storage or derivative data computed based on content in or referenced by the conglomerate data record. The stream consolidation engine can publish the conglomerate data record in a consolidated data stream. The consolidated data stream can be substantially synchronous to at least one of the input data streams.
