Abstract: Techniques are provided for sharing data among computing devices. In one technique, a first device broadcasts wireless data and establishes a wireless connection with a second device. The first device receives authorization data and first entity data from the second device. The first device authorizes the second device based on the authorization data. The first device then sends second entity data through the wireless connection to the second computing device. The first device sends the first entity data over a network to a remote server system. The first device receives, from the remote server system, entity data that pertains to an entity that is identified by the first entity data. The first device may then display at least a portion of the entity data on a screen of the first device.

Abstract: Examples described herein provide various devices that enable users to participate in a session. The examples allow a user that is unable to hear, or that is incapable of hearing, to participate in an in-session voice chat by receiving text messages that have been converted from speech to text (e.g., transcribed messages). The user enables a speech-to-text conversion feature on his or her own device. Based on the enabled feature, a notification can be sent to other devices participating in the session. Based on the notification, the other devices are tasked with capturing utterances and sending corresponding speech data to a speech-to-text conversion device so that voice communications can be converted to text messages. Subsequent to conversion, the text messages can be displayed in a chat interface presented as part of the displayed content for the session.

Abstract: A computing device is provided, comprising a processor configured to receive a set of measurements of a vector x of acoustic data, including noise, interference, and a signal of interest. The processor may express x in a frequency domain discretized in a plurality of intervals. For each interval, the processor may generate an estimate ?x of a covariance matrix of x. For each ?x, the processor may use acoustic imaging to obtain an estimate ? of a spatial source distribution. For each ?, the processor may remove the signal of interest to produce an estimate ? of a noise and interference spatial source distribution. For each ?, the processor may generate an estimate ?n of a noise and interference covariance matrix. The processor may generate a beamformer configured to remove noise and interference from the acoustic data, wherein the noise and interference at each frequency are identified using ?n.

Abstract: Monitoring the health of a computer system and suggesting an order of repair when problems within the computer system have been identified. Problem(s) and problem entity(s) within the computer system are identified during monitoring. Relationship(s) of the problem entities with other entities in the computer system are identified. A relationship type for each of the identified relationship(s) is determined. A combination of the identified problem(s), the identified problem entity(s), and the determined relationship type(s) is analyzed to determine an order in which repairs of one or more user-visible entities of the computing system should occur in order to address the identified problem(s). An alert comprising the determined order of the repairs is then presented to a user.

Abstract: A cloud manager controls the deployment and management of machines for an online service. A build system creates deployment-ready virtual hard disks (VHDs) that are installed on machines that are spread across one or more networks in farms that each may include different configurations. The build system is configured to build VHDs of differing configurations that depend on a role of the virtual machine (VM) for which the VHD will be used. The build system uses the VHDs to create virtual machines (VMs) in both test and production environments for the online service. The cloud manager system automatically provisions machines with the created virtual hard disks (VHDs). Identical VHDs can be installed directly on the machines that have already been tested.

For example, some of the innovations relate to encoding that includes adaptive switching of color spaces between units within a video sequence. Other innovations relate to encoding that includes adaptive switching of color sampling rates between units within a video sequence. Still other innovations relate to encoding that includes adaptive switching of bit depths between units within a video sequence.

Abstract: Techniques for identifying a stack frame responsible for resource usage are described. For instance, techniques described herein enable a particular process and a particular stack frame and/or set of stack frames of the process that are high resource consumers to be identified. According to various implementations, resource usage of a process is observed and recorded over a period of time. A data structure is generated that characterizes the resource usage of the process over the sampling period. The data structure be evaluated to identify a stack frame that is responsible for excess resource consumption. In at least some implementations, a remedial procedure can be performed to attempt to reduce the process's resource usage.

Abstract: A dialog system for use in a multi-user, multi-domain environment. The dialog system understands user requests when multiple users are interacting with each other as well as the dialog system. The dialog system uses multi-human conversational context to improve domain detection. Using interactions between multiple users allows the dialog system to better interpret machine directed conversational inputs in multi-user conversational systems. The dialog system employs topic segmentation to chunk conversations for determining context boundaries. Using general topic segmentation methods, as well as the specific domain detector trained with conversational inputs collected by a single user system, allows the dialog system to better determine the relevant context. The use of conversational context helps reduce the domain detection error rate, especially in certain domains, and allows for better interactions with users when the machine addressed turns are not recognized or are ambiguous.

Abstract: A technique for multi-camera object tracking is disclosed that preserves privacy of imagery from each camera or group of cameras. This technique uses secure multi-party computation to compute a distance metric across data from multiple cameras without revealing any information to operators of the cameras except whether or not an object was observed by both cameras. This is achieved by a distance metric learning technique that reduces the computing complexity of secure computation while maintaining object identification accuracy.

Abstract: Preserving memory values during replay includes identifying trace sections that each represents events executed by an entity over a period of time. A parallel replay of trace sections is performed at a plurality of processing units. While performing the parallel replay, a persistence data structure corresponding to each trace section is maintained. This includes, for each trace section, storing, in the trace section's persistence data structure, a record of each memory address consumed by the processing unit while replaying the trace section, and a most recent memory value stored at each memory address. Returning a memory value during replay includes identifying relevant persistence data structures, and searching these data structures, in turn, based on a defined ordering. When a relevant memory address is identified during the search, the search is ceased and the value associated at the memory address, as stored in a persistence data structure, is returned.

Abstract: Booting a machine in a secure fashion in a potentially unsecure environment. The method includes a target machine beginning a boot process. The method further includes the target machine determining that it needs provisioning data to continue booting. The target machine contacts a secure infrastructure to obtain the provisioning data. The target machine provides an identity claim that can be verified by the secure infrastructure. As a result of the secure infrastructure verifying the identity claim, the target machine receives a request from the secure infrastructure to establish a key sealed to the target machine. The target machine provides the established key to the secure infrastructure. The target machine receives the provisioning data from the secure infrastructure. The provisioning data is encrypted to the established key. The target machine decrypts the encrypted provisioning data, and uses the provisioning data to finish booting.

Abstract: The subject disclosure is directed towards partially recalling file ranges of deduplicated files based on tracking dirty (write modified) ranges (user writes) in a way that eliminates or minimizes reading and writing already-optimized adjacent data. The granularity of the ranges does not depend on any file-system granularity for tracking ranges. In one aspect, lazy flushing of tracking data that preserves data-integrity and crash-consistency is provided. In one aspect, also described is supporting granular partial recall on an open file while a data deduplication system is optimizing that file.

Abstract: System and techniques for activity sensing online preference assay are described herein. An initial indication of an online activity preference for a member of a social network service may be obtained. A plurality of member activities corresponding with the online activity preference for a period of time subsequent to obtaining the initial indication may be collected. Respective decision trees of a set of decision trees may be traversed based on a set of inputs comprising the collected plurality of member activities to determine a probability that the online activity preference corresponds with the member. An actual online activity preference may be derived for the member using an aggregation of the determined probability for the respective decision trees of the set of decision trees. Social network content items may be filtered for the member based on the actual online activity preference.

Abstract: Methods for preprocessing pixel data using a Direct Memory Access (DMA) engine during a data transfer of the pixel data from a first memory (e.g., a DRAM) to a second memory (e.g., an SRAM) are described. The pixel data may derive from a color camera or a depth camera in which individual pixel values are not a multiple of eight bits. In some cases, the DMA engine may perform a variety of image processing operations on the pixel data prior to the pixel data being written into the second memory. In one embodiment, the DMA engine may be configured to determine whether one or more pixels corresponding with the pixel data may be invalidated or skipped based on a minimum pixel value threshold and a maximum pixel value threshold and to embed pixel skipping information within unused bits of the pixel data.

Abstract: The disclosed embodiments provide a system for updating an index structure of a graph database storing a graph. During operation, the system includes, in the index structure, a first compressed edge store containing a first compact representation of edges in the graph at a first virtual time and a first series of updates to the edges after the first virtual time. At a second virtual time, the system creates a second compact representation of the edges from the first compact representation and the first series of updates. The system then appends, to the second compact representation, a second series of updates to the edges after the second virtual time to produce a second compressed edge store. Finally, the system updates the index structure by atomically replacing, in the index structure, a reference to the first compressed edge store with a reference to the second compressed edge store.

Abstract: A first surface of a heat source is spaced from a support by a first gap, in a thermal path from the first surface to the support. A second surface of the heat source, opposite to the first surface, is spaced by a second gap from a heat sink, in a thermal path from the second surface to the heat sink. The thermal path to the support provides a first thermal resistance, based on a gap spacing of the first gap and the thermal path to the heat sink provides a second thermal resistance, based on a gap spacing of the second gap.
