Abstract: Examples of the present disclosure describe systems and methods for using a host DNS local cache to enable DNS resolution during network connectivity issues. In examples, a DNS request from a virtual environment executing on a host device is received by a DNS forwarder implemented within the host device. The DNS forwarder determines that a DNS resolver external to the host device is unreachable to provide a DNS response for a domain name in the DNS request. In response to determining the DNS resolver is unreachable, the DNS forwarder identifies a DNS response corresponding to the domain name within a DNS local cache implemented within the host device. The DNS forwarder provides the DNS response to the virtual environment to satisfy the DNS request.

Abstract: Disclosed herein is a system and method to synchronize files from a hosted file system where the client endpoint devices have direct access to the files stored on a hosted file store. When the client desires to synchronize with the files stored on the hosted file store the process identifies a sync role that can process the request. The particular sync role does not need to maintain state with the client device or the file store. The state necessary for the processing of the synchronization process is maintained separate from the sync role such that any sync role in the system can pick up the requests and process the requests. Once the role has been selected the synchronization process proceeds as normal. As state is not maintained by the sync role multiple roles can process the request or two roles can handle different portions of the process.

Abstract: Systems and methods for determining an allocation plan for allocating virtual machines (VMs) to a hosted service utilizes a demand forecast that predicts future demand for VMs, a response curve that correlates user experience to VM utilization, and an estimated spot eviction rate to determine the allocation plan. The demand forecast, the response curve and the eviction rate are processed using mixed-integer optimization to determine the numbers of VMs of each allocation type that should be online at any given time to meet demand.

Abstract: A method of and system for implementing a safe deployment of a first feature in a computing environment is carried out by receiving registration information for the first feature, the registration information including a second feature on which the first feature depends or a feature type on which the first feature depends. Based on the second feature or the feature type, a target build version that meets dependency requirements of the second feature or the feature type is then identified before obtaining a list of build versions for a plurality of computing devices in the computing environment. From among the plurality of computing devices, one or more computing devices that have build versions that meet the target build version are then identified before marking the identified computing devices as being available for deployment of the feature and advancing deployment of the feature to those computing devices.

Abstract: Video messaging systems and methods utilize a video messaging component based on a video messaging component container stored in a data store. The video messaging component container includes a collaborative video list that shows a list of video content generated by users of the video messaging component. Iterations of the video messaging component are rendered in host applications on client devices. As video content is generated by the iterations, the collaborative video list is updated to include the video content, and the iterations of the video messaging component are updated to reflect changes to the collaborative video list in real-time.

Abstract: Methods for one click monitors in impact time detection for noise reduction in at-scale monitoring are performed by systems and devices. The methods automatically configure time window sizes and numbers of consecutive time windows for optimally detecting system alerts in at-scale systems and per dimension combinations, including updating settings over time to adapt to changing system behaviors. The past behavior of system performance metrics are analyzed to match configuration options and determine a best fitting or optimal combination of a highest detection accuracy in lowest time to detect for alerting. Optimal monitoring configurations are determined for each of up to hundreds of thousands of the metric dimensions across the system, and an end user is enabled to apply the determined, optimal configurations for system monitoring with a single selection.

Abstract: Compilation is supported and improved by varying the order of invocation of register allocation heuristics during code generation. A particular invocation order may be chosen based on one or more compilation scenario properties, such as a target processor architecture, a target operating system, a kind of source code being compiled, or optimization targets for the compiler or the generated code, or a mix thereof. Suitable heuristics invocation orders may be produced efficiently and effectively using a genetic algorithm that is adapted to make a population of invocation orders, select parents, create offspring, and assess invocation order fitness, until the population converges on optimal orders. Invocation order fitness assessments may be based on actual performance or simulated performance.

Abstract: Methods for composable user journeys for user authentication via an identity experience framework are performed by systems and apparatuses. Initiating a user authentication process for an application triggers application calls for dynamic invocation of a specific identity policy, required by the application, of a number of identity policies managed by a host of the identity experience framework. User interfaces defined by the identity policies are provided from the host to the application for interaction by the user and entry of identity information needed to authenticate the user according to specified verification providers. Identity claims and token requests are provided from the application to the host which then authenticates the identity claims via the verification providers and mints a token that includes the claims required by the application, according to the identity policy. The application consumes the token to complete the token request and allow the user access to the application.

A second annotation of the text and a link between the second annotation and a corresponding portion of the text may be received from a human user. The first annotation and its corresponding link may be merged with the second annotation and its corresponding link. Training data may be provided to the engine in the form of the text and the merged annotations and links.

Abstract: This disclosure describes particles and techniques for storing oligonucleotides that provide stable, long-term protection yet are also compostable. A core is coated with a layer of oligonucleotides and encapsulated under an outer layer of non-porous, hydrolyzed organosilicon disulfide. The hydrolyzed organosilicon disulfide protects the oligonucleotides from oxidative and thermal damage under typical storage conditions. One suitable organosilicon disulfide is bis(3-triethoxysilylpropyl) disulfide (BTSPD). The oligonucleotides may be retrieved by contacting the particles with a reducing agent that degrades the disulfide bonds in the outer layer. The disulfide bonds enable removal of the protective encapsulation without the use of dangerous chemicals such as hydrogen fluoride. Instead of retrieving the oligonucleotides, the particles may be disposed of in a composting environment. In an implementation, the oligonucleotides are artificially synthesized and encode digital information.

Abstract: Methods, systems, and computer storage media for providing reduced-latency data operations for data or storage in file systems. The file system implements a set of policies that indicate how data operations are performed. In operation, a request for access to storage of a file system to perform a data operation is received. The file system supports both a bitmap representation and a range-only representation of the storage. A bitmap representation of a region for performing the data operation is communicated because, for certain data operations, the file system operates based on communicating only bitmap representations while restricting access to range-only representations. The range-only representations are a compacted representation of storage of the file system. Based on the bitmap representation of the region, the storage of the file system is accessed. The bitmap representation of the region further includes a bitmap lock that restricts access to storage corresponding to the bitmap representation.
