Abstract: Conversion that includes multiple targets or sources of a data store migration may be performed. A request that specifies a mapping between multiple sources and one or more targets, one or more sources and multiple targets, or multiple sources and multiple targets may be created for data store migration. Metadata may be obtained for the selected sources and targets for the mapping. Conversion scripts may then be generated for the mapping based on an analysis using the metadata. The conversion scripts may then be stored for later execution.

Abstract: Quorum-based access control management may be implemented. Quorum controls may be created for determining whether to perform or deny access control operations to perform privileged tasks. When an access control operation is received, approval of the operation may be requested from members for the quorum control. If a policy for the quorum control is satisfied by approval responses, then approval to perform the access control operation may be provided.

Abstract: An aggregate representation of a collection of source code examples is constructed. The collection includes positive examples that conform to a coding practice and negative examples do not conform to the coding practice. The aggregate representation includes nodes corresponding to source code elements, and edges representing relationships between code elements. Using an iterative analysis of the aggregate representation, a rule to automatically detect non-conformance is generated. The rule is used to provide an indication that a set of source code is non-conformant.

Abstract: When a user accesses content describing an item able to be purchased using a first website, and the user subsequently purchases the item using a second website within a threshold length of time of the access to the content, the purchase may be inferred to have been induced by the content, even though the content would normally direct the user to the first website. To correlate purchases across different websites, data identifying the user's device or a user account and data identifying the item is acquired when the content is accessed by the user. Subsequently, additional data is acquired when the item is purchased. If the additional data corresponds to the previous data, this may be used to determine that the same user has purchased the same item described by the content that was accessed.

Abstract: This disclosure describes, in part, an electronic device for converting inputs received by control devices. For instance, a user may attach the electronic device to a control device. The electronic device may then configure the control device with a network application by associating various input devices of the control device with controls of the network application. After configuring the control device, the electronic device may receive input data representing inputs received by the control device. Using the associations, the electronic device may generate control data representing the controls that are associated with the inputs. The electronic device may then send the control data to a remote system, which may use the control data to update a state of the network application. The electronic device may perform similar processes in order to allow the user to use different types of control devices to control the network application.

Abstract: Systems and methods are provided to improve a communication channel dynamically and autonomously based on the status of the communication traffic on the communication channel between a first integrated circuit (IC) and a second IC. The communication traffic on the communication channel can be monitored, and latency, bandwidth, link quality, or power consumption associated with the communication channel for the monitored communication traffic can be determined dynamically. A modified protocol for the communication channel that can improve the communication channel as compared to an existing protocol can be determined based on the information related to the latency, bandwidth, link quality, or the power consumption. The existing protocol can be changed autonomously to the modified protocol as the communication traffic varies.

Abstract: This disclosure proposes systems and methods for processing natural language inputs using data associated with multiple language recognition contexts (LRC). A system using multiple LRCs can receive input data from a device, identify a first identifier associated with the device, and further identify second identifiers associated with the first identifier and representing candidate users of the device. The system can access language processing data used for natural language processing for the LRCs corresponding to each of the first and second identifiers, and process the input data using the language processing data at one or more stages of automatic speech recognition, natural language understanding, entity resolution, and/or command execution. User recognition can reduce the number of candidate users, and thus the amount of data used to process the input data. Dynamic arbitration can select from between competing hypotheses representing the first identifier and a second identifier, respectively.

In one embodiment, an example container conveyance system may include a set of rails having a first rail and a second rail, the set of rails configured to guide a container from an upright position at a first point along the set of rails to an inverted position at a second point along the set of rails. The system may include a drive mechanism configured to propel the container along the set of rails, and a conveyor disposed under a portion of the set of rails corresponding to the second point.

Abstract: A system that is capable of resolving anaphora using timing data received by a local device. A local device outputs audio representing a list of entries. The audio may represent synthesized speech of the list of entries. A user can interrupt the device to select an entry in the list, such as by saying “that one.” The local device can determine an offset time representing the time between when audio playback began and when the user interrupted. The local device sends the offset time and audio data representing the utterance to a speech processing system which can then use the offset time and stored data to identify which entry on the list was most recently output by the local device when the user interrupted. The system can then resolve anaphora to match that entry and can perform additional processing based on the referred to item.

Abstract: The present disclosure generally relates to systems and methods for generating termination notification of an experiment to be presented through a user interface. In some implementation examples, a termination notification system generates a probability value that is valid as of a time period of an experiment at a predetermined point in time based on at least data sample obtained during the time period, predicted sample sizes of each time period of the experiment, or probability values generated prior to the time period. Responsive to determining that the probability value that is valid as of the time period satisfies a threshold value, the termination notification system causes the user interface to present the termination notification that, when selected, causes the experiment to terminate prior to completion of a predicted duration of the experiment.

Abstract: A replicated database can be provisioned that provides primary and secondary replicas that can be provisioned in different data zones or geographical locations. The database can be installed on the primary replica, and both the primary and secondary replica can have installed a block level replication mechanism that allows any I/O operation to be replicated by between the primary and secondary replicas. Any failure or outage of the primary replica can be addressed by performing a failover operation to the secondary replica. A DNS name or other such approach can be used such that the name can be aliased to the secondary replica during a failover, such that there is no action needed on the part of the customer to utilize the “new” primary replica. The creation of the database and provisioning of the replicated instance can be initiated using a Web service call to a control environment.

Abstract: Disclosed are various embodiments for resource allocation policies for a hosted computing environment that can be configured by organizations that use the hosted computing environment under a utility computing model. In one embodiment, a resource allocation request to allocate a computing resource within a hosted computing environment is received. The resource allocation request is associated with an account of an organization. It is determined that a fulfillment of the resource allocation request would violate a resource allocation policy configured by the organization within the hosted computing environment. The resource allocation request is prevented from being automatically fulfilled in response to determining that the fulfillment of the resource allocation request would violate the resource allocation policy.

Abstract: A videoconference among a plurality of participants may be hosted, wherein the plurality of participants comprise Internet Protocol (IP)-connected participants and a Public Switched Telephone Network (PSTN)-connected participant. The IP-connected participants may send and receive audio content and video content of the videoconference via IP-based connections. The PSTN-connected participant may send and receive the audio content of the videoconference via a PSTN connection. Additional content from the videoconference may also be transmitted to the PSTN-connected participant, for example as text messages via the PSTN connection. The additional content may include, for example, images of a videoconference screen share, chat posts, polls, and the like. Images may be transmitted in the additional content based on video status change events, such as switching slides or pages in a screen share.

Abstract: A commonly designed processor heat exchanger decouples the mounting hardware used to mount the heat exchanger to a processor from the heat exchanger itself. This allows a single heat exchanger design to be mounted to various different types of processors using processor customized mounting brackets that engage with flanges extending out from a body of the heat exchanger.

Abstract: A simulation environment (e.g., multi-player game) may be hosted by multiple nodes of a provider network. The number of nodes may increase or decrease, depending on the load on the simulation. Each node may be assigned a root key that includes 3D coordinates. The nodes may maintain a circular keyspace that includes the x-axis coordinates, the y-axis coordinates, and the z-axis coordinates, according to a consistent hashing algorithm. A given node may have any number of successor or predecessor nodes along each axis keyspace. If load on a particular node increases above a threshold amount, a new node may be allocated and insert itself into the 3D keyspace, taking over authority for any entities that are located within a portion of the volume that was previously managed by the particular node.

A system may determine that a received spoken input triggers an alternative input representation for presenting. The system may output data corresponding to the alternative input representation in response to the received spoken input, and the system may receive user feedback from the user. The system may store the user feedback and processing data corresponding to processing of the alternative input representation, which may be later used to update an alternative input component configured to determine alternative input representations for spoken inputs.

Abstract: Techniques and technologies for an Internet Protocol (IP) address management (IPAM) system to track and manage IP address workflows in a network. The IPAM system can be used to define and enforce management policies or rules regarding IP address management, such as allocation policies, refill policies, and so forth. For instance, the IPAM system can enforce allocation policies that define rules to allow or deny allocation of IP addresses based on types of resources for which the IP addresses are requested, registered user accounts that are requesting the IP addresses, the purpose of the resources receiving the IP addresses, and so forth. Additionally, the IPAM system can enforce refill policies that define rules for replenishing inventories of IP addresses that have been allocated for different domains in the network. The IPAM system can improve the management of IP address workflows by enforcing policy and tracking IP address workflows in networks.

The subscribing client devices can access and fetch the streams from the edge computing resources, which can be presented on the client devices as part of a conferencing session experience.

Abstract: Coordinated operation of a voice-controlled device and an accessory device in an environment is described. A remote system processes audio data it receives from the voice-controlled device in the environment to identify a first intent associated with a first domain, a second intent associated with a second domain, and a named entity associated with the audio data. The remote system sends, to the voice-controlled device, first information for accessing main content associated with the named entity, and a first instruction corresponding to the first intent. The remote system also sends, to the accessory device, second information for accessing control information or supplemental content associated with the main content, and a second instruction corresponding to the second intent. The first and second instructions, when processed by the devices in the environment, cause coordinated operation of the voice-controlled device and the accessory device.

Each separate live streaming session may be routed to the candidate data center. A determination that each separate live streaming session of the candidate data center is synchronized with each live streaming session of the first data center may be made. An update to a mapping of IP addresses to redirect requests from the first data center to the candidate data center.

Abstract: As agents move about a materials handling facility, tracklets representative of the position of each agent are maintained along with a confidence score indicating a confidence that the position of the agent is known. If the confidence score falls below a threshold level, image data of the agent associated with the low confidence score is obtained and processed to generate one or more embedding vectors representative of the agent at a current position. Those embedding vectors are then compared with embedding vectors of other candidate agents to determine a set of embedding vectors having a highest similarity. The candidate agent represented by the set of embedding vectors having the highest similarity score is determined to be the agent and the position of that candidate agent is updated to the current position, thereby re-identifying the agent.

Abstract: Techniques to reduce the latency in notifying that space in a memory has been freed up are described. For example, when moving data from on-chip memory of a computing engine to system memory, the computing engine can be notified that its on-chip memory is free before an acknowledgment is provided by the system memory that the data being moved has been written into the system memory. The computing engine can be given access to the on-chip memory sooner by generating an early semaphore update based on a determination that the set of data being moved to system memory has been read out from the on-chip memory. The early semaphore update need not wait for the acknowledgement from the system memory, thus reducing the latency of notifying the computing engine that the on-chip memory is free.

Abstract: Systems and methods are provided for exposing disparate storage systems and technologies to compute instances through a unified file system interface that is agnostic to the underlying storage systems and technologies. A file system namespace service may provide the ability to compose a file system from different storage technologies and systems (e.g., block storage, object storage, etc.). The file system namespace service may also provide the ability to layer different storage services (e.g., by treating local block storage volume as a write back cache, by treating a file system as a read-through cache in front of an object storage service, etc.), and/or the ability to bind virtual files to other compute instances and/or storage systems.

Abstract: Techniques for implementing a streaming remote procedure call (RPC) mechanism using distributed processing components of a system are described. A first processing component sends a connect message to a second processing component. Thereafter, the first processing component sends different instances of data to the second processing component as the different instances of data are determined by the first processing component. The second processing component performs at least some processes as the second processing component receives the different instances of data. After the first processing component sends all relevant data to the second processing component, the first processing component sends a commit message to the second processing component. Based at least in part on receiving the commit message, the second processing component determines finishes its processing, and sends result data to the first processing component.

Abstract: Systems and methods for evaluating the performance of three-dimensional (3D) sensors can include, for example, obtaining, via a 3D sensor in a testing apparatus, range information of a scene within a field-of-view (FOV) of the 3D sensor. The scene includes a plurality of targets disposed within the testing apparatus. Each of the plurality of targets is located at a different distance from the 3D sensor in the testing apparatus. A validation of the performance of the 3D sensor at the different distances is performed at a same point in time, based on the range information. An indication of a result of the validation is provided.

Abstract: The maintenance of a materialized view created and managed by a materialized view management platform may be dynamically adjusted. The performance of updates to a materialized view are monitored to trigger different events to make adjustments to the performance of subsequent updates. The materialized view management platform can adequately scale to handle changes to data sources as inputs to the maintenance of the materialized view, as well as make other adjustments handle various changes in the capability of the target data store to receive updates to the materialized view (e.g., target data store outages).

Abstract: A cryptographic key management service receives a request, associated with a principal, to use a cryptographic key to perform a cryptographic operation. In response to the request, the service determines whether a rate limit specific to the principal is associated with the cryptographic key. If the rate limit is associated with the cryptographic key, the service generates a response to the request that conforms to the rate limit. The service provides the response in response to the request.

Abstract: A system adapted to link email conversations is disclosed. An email client identifies email conversations from email header information and presents the conversations along with other emails in a user's inbox. The user interface receives user inputs selecting first and second email conversations and specifying that the two should be linked. The email client generates an identifier and associates the identifier with emails that are comprised in the selected first and second conversations. When a recipient receives an email that is part of a conversation that has been linked by another user, the recipient's email client notifies the user of the prior linking and provides a button with which the recipient may also implement the link. A user may select to create a new email and link the new email to an existing conversation. An identifier is generated and associated with the new email and emails in the selected conversation.

Abstract: Historical time-series data can be analyzed using a probabilistic model to determine one or more distributions, including at least a normal distribution and an anomaly distribution. These distributions can be analyzed to obtain values for distribution parameters, such as mean, standard deviation, and density, as well as other statistical parameters, for use in building a forecasting model. This model can analyze the time-series data to predict or forecast actionable anomalies at one or more future points or periods in time, such as may exceed a determined anomaly threshold with at least a minimum amount of confidence. A determination can be made as to one or more actions to take in anticipation of the anomalous event, or volume of events, such as to attempt to prevent the occurrence or to be better positioned to handle the occurrence. Such forecasting or prediction can utilize both modeling and feature engineering.

Abstract: Systems, methods, and computer-readable media are disclosed for language-agnostic subtitle drift detection and correction. A method may include determining subtitles and/or captions from media content (e.g., videos), the subtitles and/or captions corresponding to dialog in the media content. The subtitles may be broken up into segments which may be analyzed to determine a likelihood of drift (e.g., a likelihood that the subtitles are out of synchronization with the dialog in the media content) for each segment. For segments with a high likelihood of drift, the subtitles may be incrementally adjusted to determine an adjustment that eliminates and/or reduces the amount of drift, and the drift in the segment may be corrected based on the drift amount detected. A linear regression model and/or human blocks determined by human operators may be used to otherwise optimize drift correction.

Abstract: This disclosure describes, in part, techniques for providing network applications. For instance, system(s) may install a network application on a first virtual server. The system(s) may then receive first data representing events that occurred during a first launching of the network application on the first virtual server. Using the events, the system(s) may generate second data for optimizing a second launching of the network application on a second virtual server and store the second data in one or more databases. As such, after installing the network application on the second virtual server, the system(s) may provide the second virtual server with the second data so that the second virtual server may use the second data to optimize the second launching of the network application. In some examples, using the second data reduces the amount of time that it takes for the second virtual server to launch the network application.
