Abstract: Techniques and tools for video coding/decoding with motion resolution switching and sub-block transform coding/decoding are described. For example, a video encoder adaptively switches the resolution of motion estimation and compensation between quarter-pixel and half-pixel resolutions; a corresponding video decoder adaptively switches the resolution of motion compensation between quarter-pixel and half-pixel resolutions. For sub-block transform sizes, for example, a video encoder adaptively switches between 8×8, 8×4, and 4×8 DCTs when encoding 8×8 prediction residual blocks; a corresponding video decoder switches between 8×8, 8×4, and 4×8 inverse DCTs during decoding.

Abstract: Dynamically-generated images sized according to a requesting web client application display resolution are provided. The client application may calculate a target display resolution and pass the target display resolution as an input parameter with a request to a server for application content. The server may use the desired size input parameter to determine an optimal image size for the target display resolution. The server may render the application content as one or more images to the optimal image size and send the rendered image(s) to the client application. A determination may be made by the client application to display the image(s) at the size received or to scale the server-provided image(s). If the available area in the client application pane changes, the client application may recalculate the target display resolution and issue a new request to the server with the new target display resolution as the desired size input parameter.

Abstract: Techniques for a contextual new tab experience in a heterogeneous tab environment are described. In at least some implementations, relevant content associated with a user's current task is determined based on contextual information collected from tabs presented in a heterogeneous tab environment. According to various implementations, a new tab is launched displaying the relevant content in the heterogeneous tab environment. Thus, contextually relevant content can be determined from a current task and displayed in a single location via a heterogeneous tab environment.

Abstract: Optimizations are provided for asynchronously performing camera frame allocations in which camera frame requests are received from multiple image consuming components that each compete for use of one or more shared cameras to obtain one or more digital images of a surrounding environment. After receiving a batch of multiple camera frame requests, an arbiter pre-processes those requests by determining an execution order for each request in the batch. Once this execution order is established, then the arbiter sends those requests to a camera system for processing. Processing a request includes obtaining one or more digital images of the surrounding environment. In this manner, significant advantages are realized because the arbiter dynamically allocates the camera system's processing.

Abstract: Attention-based scheduling is provided. Most people's energy levels and cognitive functioning fluctuate throughout the day. Typically, the time of day when a person feels more energetic or has a higher attention span is the time in the person's day when the individual has the highest productivity potential. While at off-peak times, a person may have less attention, which can make it harder for the individual to be effective. An attention-based schedule system identifies a user's high and off-peak times based on one or more attention-based factors. When a meeting or appointment is scheduled and an attention-based scheduling conflict is determined, the user or another scheduler of the calendar item is notified, and in some examples, alternate time suggestions are provided. In some examples, off-peak times are blocked off from the user's calendar.

Abstract: A first thread receives a start movement command and a parametric curve from a second thread in response to the second thread receiving an input to move an element that is rendered in an interface. The parametric curve defines parameters for movement of an element. The first thread calculates a positioning of the element on the interface using the parametric curve. Then, the first thread positions the element in the interface based on the positioning and continues to calculate the positioning and position the element in the interface using the parametric curve until a stop movement command is received from the second thread.

Abstract: In an example, a first hash function is performed on job posting features extracted from a job posting to obtain hashed job posting features. The hashed job posting features are stored in a forward-index corresponding to the job posting in the database. When a job search query is received from a first member of a social networking service, job search query features are extracted from the job search query and a second hash function is performed on the job search query features. The hashed job posting features and the hashed job search query features are fed to a job posting result ranking model trained via a machine learning algorithm to compare the hashed job posting features to the hashed job search query features to generate an application likelihood score indicating a likelihood that the first member will apply for a job corresponding to the job posting.

Abstract: Tentatively executing an entity includes performing a first, execution of an entity. At a point in the first execution, the first execution is suspended and input specifying an alternate value for a runtime data element is received. Based on the input, a second execution of the entity is performed starting at the point in the first execution, while enabling the first execution to be later resumed unaffected by the second execution. This second execution includes setting the runtime data element to the alternate value, and emulating one or more memory writes performed by the entity during the second execution. The first execution of the entity could comprise a live execution, an execution that is based on trace data, an execution based on a process dump, etc.

Abstract: Technologies are described for enabling co-streaming of live video game streams by multiple broadcasters. For example, broadcasters that are eligible to co-stream can be determined. Invitations can be sent to the broadcasters to join a co-stream. After acceptance, a co-stream can be created. The co-stream can be streamed to viewer devices.

Abstract: A collaborative diagnostic system monitors events in a system and identifies a causality chain from a detected performance issue to the root cause of that performance issue. The collaborative diagnostic system includes multiple issue detectors, multiple analysis core modules, and multiple scenario modules that work together to identify the causality chain and root cause. Each issue detector is a module or component that includes logic to detect known behaviors in the system, such as performance issues in the system. Each analysis core module includes logic to analyze and correlate low level system behavior within a conceptual area. Within each analysis core module are one or more diagnostic modules that are specific to that analysis core module to help determine what is happening in the system. Each scenario module includes logic to take an appropriate responsive action in response to the root cause of a performance issue being determined.

Abstract: Systems, methods, and computer-readable storage media are provided for enabling client devices to remotely control a shared application. A remote control service receives a request for a shared application to be controlled by a multiple client devices. Based on this request, the client devices are enabled to remotely control the shared application. A command from one of the client devices is received at the remote control service to modify a display of the shared application without the client device receiving any sensitive information associated with the shared application or the computing device running the shared application. The command is used to cause a modification to the display of the shared application.

Abstract: Monitoring of cloud computing environments subject to different data control policies is performed in a manner that ensures compliance with the data control policies. A monitoring service is located in a remote cloud computing environment separate from the cloud computing environments being monitored. The monitoring service does not have access to restricted data in the cloud computing environments, including access control data, such that the monitoring service cannot directly interact with network devices. The monitoring service issues requests for monitoring data to device access services in the cloud computing environments. In response to the requests, the device access services obtain access control data to access the network devices and obtain the requested data, which is returned to the monitoring service.

Abstract: Systems and methods for enabling the real-time sharing of document edits as rumored changes are disclosed herein. As an editor makes changes to a document being coauthored, those edits may be entered into the editor's copy as concrete changes that are incorporated into the copy's backing store, and may be shared as rumored changes to endpoints that are not incorporated into their backing stores. Rumored changes display the endpoint's real-time interpretation of an edit made by an editor, but are not incorporated as concrete changes until a save command occurs. By enabling the real-time display of edits as rumored changes, editing users can make edits naturally and endpoint users can see those edits being made with a reduced chance of corruption on the endpoint and lower network overhead and processing by the computing devices involved in the coauthoring environment.

Abstract: The present disclosure describes pattern detections for storing multiple values in a compound object. A compound object is a value that stores multiple values in a single cell, wherein those multiple values are organized according to a defined structure. The compound object may store multiple values according to a known defined data structure. In embodiments, the compound object may store multiple values as any nested combination of any one of the known or user-defined data structures (e.g., nesting an array within a vector, or nesting a record within a record, or nesting matrices within a table, etc.). Each of the values stored in the compound object are individually referenceable and can fully participate with spreadsheet functionality including calculations, referencing, and formatting.
