Abstract: A computer-implemented method executed by one or more processors, the method includes monitoring execution of program code executed by a first processor component; and monitoring execution of program code executed by a second processor component. A computing system stores data identifying hardware events in a memory buffer. The stored events occur across processor units that include at least the first and second processor components. The hardware events each include an event time stamp and metadata characterizing the event. The system generates a data structure identifying the hardware events. The data structure arranges the events in a time ordered sequence and associates events with at least the first or second processor components. The system stores the data structure in a memory bank of a host device and uses the data structure to analyze performance of the program code executed by the first or second processor components.

Abstract: A video hosting service receives and processes a source video to generate an efficiently compressed media file. The source video is transcoded to an intermediate video and corresponding audio. The video hosting service selects a subset of video frames from the intermediate video as still images and identifies the timing information associated with each selected still image. The selection process may be dependent on information associated with the video such as a video classification. The video hosting service encodes the selected still images and the audio data of the source video, and generates a compressed media file for transmission to a client device. The compressed media file does not include motion data associated with the selected still images to reduce the size of the compressed media file. A client device receives the compressed media file and plays the still images and associated audio data.

Abstract: A video hosting system is provided for storing and managing broadcasts. A user device communicates with the video hosting system to create or join a broadcast. The user device transmits video to the video hosting system for inclusion in the broadcast that may be joined by video transmitted by other user devices. Users of user devices may also search for nearby broadcasts to join. The video hosting system associates a time and place for broadcasts and limits users from joining a broadcast who do not correspond to the time and place of the broadcast. Users of the video hosting system may search for and view videos associated with a broadcast and compile portions of videos associated with a broadcast to create a compilation.

Abstract: A message sent by a message sender to a message receiver can be, e.g., upon arrival at a message system server, ranked or scored based on attributes of the message sender such as influence and engagement. Influence can relate to a determination of how influential the message sender is. Engagement can relate to a determination of how interested the message sender is in content published or syndicated by the message receiver. The message score can reflect a combination of an influence score and an engagement score. Scored messages can be sorted or filtered according to a desired element and a presentation of messages stored by the message system can be updated (e.g., ordered and scored) according to the desired element.

Abstract: A multi-queue cache is configured with an initial configuration, where the initial configuration includes one or more queues for storing data items. Each of the one or more queues has an initial size. Thereafter, the multi-queue cache is operated according to a multi-queue cache replacement algorithm. During operation, access patterns for the multi-queue cache are analyzed. Based on the access patterns, an updated configuration for the multi-queue cache is determined. Thereafter, the configuration of the multi-queue cache is modified during operation. The modifying includes adjusting the size of at least one of the one or more queues according to the determined updated configuration for the multi-queue cache.

Abstract: Techniques for using contextual information relating to content presented by a television as part of a search query for an information search are presented. A search management component, at a given moment in time during presentation of television-related content by a communication device in or associated with a television, identifies contextual information associated with a section of the television-related content and generates a content identifier timestamp associated with the contextual information and the section of television-related content. A search component augments a search query using the contextual information to facilitate customization of a subset of search results based on the contextual information. The contextual information in the search query can facilitate disambiguating the search query or promoting a search result over another search result in the subset of search results, based on the contextual information, to facilitate customization of the subset of search results.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A request for content is received from a user device. One or more candidate content items that are responsive to the request are identified from an inventory of content items. For each candidate content item, an expected performance measure associated with a respective candidate content item is determined. The expected performance measure for each respective candidate content item is compared to a predetermined threshold. When none of the candidate content items have an expected performance measure that exceeds the threshold, a notification is generated, including generating one or more queries, responsive to the request for inclusion in the notification. The notification is provided responsive to the request and for presentation to the user in lieu of a content item.
