Abstract: Optimization opportunities are located and documented to enhance code translation by compilers or interpreters. An enhanced translator scans a program syntax graph, recognizes subgraph structures, and annotates nodes of the graph to document optimization characteristics of program code entities associated with the nodes. Subgraph structures and corresponding annotations may be maintained in an optimization catalog, distinct from any particular optimizable program. Optimizers improve program code translation based on the annotated syntax graph. Optimization characteristics may specify code purity in terms of execution value ranges and execution behaviors, e.g., side-effects, local or global variable usage, I/O, by-reference parameters, and which exceptions are possible. Subgraph structures may be identified using routine names, hash values, and templates with holes any constant will fill. Parent node characteristics may be inferred from characteristics of child nodes.

Abstract: Systems, methods, and computer-readable storage media are provided for publishing, discovering, connecting with and activating services in a peer-to-peer environment. Services available in association with a first computing device are determined and encoded with instructions for accessing and understanding such services via their respective activation protocols. The encoded services are published via a publication protocol such that they are discoverable by at least a second computing device, irrespective of whether such services may be activated via the publication protocol. The second computing device discovers the available services via the publication protocol and accesses and understands the instructions associated with a desired service. Upon receipt of a request from the second computing device, via the activation protocol, to activate the requested service, the requested service is activated by the first computing device.

Abstract: Apparatus and methods are disclosed for controlling execution of register access instructions in a block-based processor architecture using a hardware structure that indicates a relative ordering of register access instruction in an instruction block. In one example of the disclosed technology, a method of operating a processor includes selecting a register access instruction of the plurality of instructions to execute based at least in part on dependencies encoded within a previous block of instructions and on stored data indicating which of the register write instructions have executed for the previous block, and executing the selected instruction. In some examples, one or more of a write mask, a read mask, a register write vector register, or a counter are used to determine register read/write dependences. Based on the encoded dependencies and the masked write vector, the next instruction block can issue when its register dependencies are available.

Abstract: A Distributed Availability Group (DAG) spans two AGs, each spanning one or more replica nodes and functioning as primary or secondary AG. A primary AG is replicated to the secondary AG synchronously or asynchronously. A failover in the DAG results in the AGs swapping their roles. Multiple DAGs can be linked together as a chain, which provides many useful features including disaster recovery across geographical regions, massive read scale (numerous readable secondary nodes), online migration of databases (across different operating systems and computing environments). The systems using DAGs can replicate databases across multiple independent high availability (HA) failover clusters using complex replication topologies and allow for manual failover and failback. The systems allow chaining of multiple AGs to provision a treelike structure of replicas and numerous secondary replicas without impacting performance.

Abstract: Systems for determining and presenting consensus based on evaluating a message conversation are described. A consensus determination application may automatically parse each message of a series of messages related to a topic, using natural language processing or similar methods, to determine one or more suggestions and corresponding opinions for the one or more suggestions contained within those messages. The consensus for each of the one or more suggestions may be presented to a user. By viewing the automatically-determined consensus, the user may, without reading and evaluating all of the messages within the conversation, understand the level of consensus regarding the topic across the group of message participants. Accordingly, user burden is reduced and users may more effectively debate ideas and present suggestions with fewer misunderstandings, leading to an overall better user experience.

Abstract: Aspects extend to automated time-synchronized electrical system commissioning. Automated electrical system commissioning in industrial/commercial settings (e.g., a data center) increases the likelihood that the electrical system functions as intended when released into production. Automated data collection devices can be time-synchronized to collect commissioning data related to electrical and other characteristics of electrical/power system equipment. Time-synchronization can be used to correlate collected data related to electrical loads, electrical harmonics, transient conditions, etc. collected from different data collection devices. A commissioning center computer system can send a local timing signal over a network to a plurality of collection devices to update/synchronize clocks at each of the plurality of data collection devices to a specified time. The commissioning center computer system can include a receiver for receiving a global (e.g., GPS, GLONASS, etc.) time signal.

The panning animation is output by the computing device to travel the calculated distance.

Abstract: Computer-implemented techniques for constructing structured database query language statements from natural language questions are disclosed. In some embodiments, a knowledge graph-based approach is employed to construct a structured database query language statement such as, for example, a Structure Query Language (SQL) statement, from a natural language question. The approach encompasses a domain knowledge graph model and a database schema wiring model. The domain knowledge graph model represents domain-specific knowledge about the underlying database data in the form of a graph having nodes and directed edges between the nodes. The database schema wiring model maps routes in the domain knowledge graph to database schema elements. The techniques allow a natural language interface system to accurately translate domain-specific natural language questions posed by users to structured database query language statements that can be executed against a structured database to answer the natural language question.

Abstract: A secure terminal configured to support a trusted execution environment that utilizes policy enforcement to filter and authorize transmissions received from a host device and destined for a remote device. Upon receiving a transmission from the host device, the secure terminal verifies that the instruction, message, or request contained within the transmission satisfy parameters set by a policy. If the transmission satisfies the parameters, then the secure terminal signs the transmission with a key unique to the trusted platform module associated with the secure terminal and forwards the signed transmission to the remote device. If the transmission fails one or more parameters within the policy, a message that details the instruction or operation contained within the transmission is exposed to a user at an output device, in which the user can authorize or reject the transmission using an input device.

A depth-compressed representation indicating the occlusion class for each of the different portions of the virtual view is output to the remote device.

Abstract: Controlled deployment of an application feature is provided. A deployment service initiates operations to control deployment of the application feature by receiving a definition of a feature of a mobile application and a group of tenants of the mobile application from a developer. The definition is used to allow the mobile application associated with the group of tenants to activate the feature. Next, a tenant identification is received from the mobile application. The tenant identification is compared to the group of tenants to detect the tenant identification as within the group of tenants. In response, an instruction is transmitted to the mobile application associated with the tenant identification to activate the feature.

Abstract: An execution environment has a deployed virtual machine image. The virtual machine image provides a service that is identified by a role. The execution environment generates a measurement of the virtual machine image and provides it to a key service to request role keys that enable operation of the virtual machine image in the execution environment. The key service determines whether the virtual machine image is mapped to the role and, if so, returns the role keys to the requesting execution environment.

Abstract: A remote procedure call channel for interprocess communication in a managed code environment ensures thread-affinity on both sides of an interprocess communication. Using the channel, calls from a first process to a second process are guaranteed to run on a same thread in a target process. Furthermore, calls from the second process back to the first process will also always execute on the same thread. An interprocess communication manager that allows thread affinity and reentrancy is able to correctly keep track of the logical thread of execution so calls are not blocked in unmanaged hosts. Furthermore, both unmanaged and managed hosts are able to make use of transparent remote call functionality provided by an interprocess communication manager for the managed code environment.

Abstract: Systems and methods are provided that automatically process message input and provide action responses according to the processing results. The automatic action response system may leverage at least one machine-learning algorithm that is trained using a dataset. The provided action responses may comprise of default action responses and/or intelligent action responses that are based at least in part on prior conversational data between a user and a sender. Some intelligent action responses may include text-based replies, which eliminate the need for a user to type a reply on a device screen, thereby saving previous time, conserving device battery life, and preserving the integrity of the device hardware. A portion of a message may be highlighted manually by a user or automatically by the action response system to initiate the automatic action response system. In this way, a more efficient and productive user experience across various devices and applications is achieved.

Abstract: Technologies are described to increase a data limit for a user of a communication application by introducing additional archive mailboxes as the original archive fills up or subsequently added archive mailboxes fill up. Thus, a user's data limit may be effectively removed through the use of N additional archive mailboxes. The additional mailboxes may be integrated into the architecture of the communication application such that their use is transparent to the user and/or an administrator of the communication application or associated service. In other examples, additional mailboxes may be used to add to the capacity of the primary mailbox (cached) as well.
