Abstract: A social networking system determines common location information included in a set of posts between a set of users. Using the determined common location information, the social networking system generates a message interface for grouping a set of messages into a conversation thread. For example, the messages may be grouped into a conversation thread based on common location information in the messages and being associated with participants sharing a social relationship. When a group conversation is created, the social networking system presents a message interface containing the conversation thread to one or more participants of the thread. The social networking system adds the set of messages to the conversation thread based on social information about the social relationships among the participants of the conversation thread. The social networking system then presents the message interface for display to one or more of the participants.

Abstract: An audio device includes a speaker array and a controller for beam-steering audio output by the speaker array to localize sound in different locations in a local area around the audio device. The audio device also includes a microphone array or a set of cameras configured to detect an object, such as a human, in the local area around the audio device. From data captured by the microphone array or the set of cameras, the audio device determines a location of the object in the local area and steers the audio output by the speaker array towards the determined location of the object. As the object moves within the local area, the audio device dynamically steers the audio output to move along with the object.

Abstract: In one embodiment, a computing device determines a window of time that is available after each operation to fill a frame buffer. The device determines a first number indicating a number of elements of a requested content that fit into a display region, an increment based on an application-specific rule, and a second number indicating a number of elements to pre-generate based on the first number and the increment.

During the window of time, the device executes at least a subset of the pre-generation tasks to pre-generate content for a corresponding subset of the select elements. The pre-generated subset of the select elements is stored in an application-tailored recycler.

Abstract: An online system accesses a content item containing a link to an external landing page. When an opportunity to present content to a viewing user occurs, the system determines a quality metric for the content item. The system further determines, based on the attributes of the external page, a quality metric for the external page. The quality metric for the external page is adjusted based on the quality metric of the content item. The system computes a value score for the content item based on the quality metrics for the content item and the external page. The content item is ranked against other content items for presentation in the opportunity. Content items are selected by the system and sent for presentation to the viewing user.
