Abstract: Techniques for coordination of content presentation operations are described herein. In some cases, a client may generate client metadata associated with client event data. The client metadata may include, for example, an indication of any one or more of a time, a frame, a location, an angle, a direction, a speed, a force, or other information associated with the client event data. Also, in some cases, the content provider may generate content provider metadata associated with image data. For example, the content provider metadata may indicate a location of a virtual camera associated with the respective image data and/or a location of one or more objects represented within the respective image data.

Abstract: An implicit certificate is based on a ring learning with errors (“RLWE”) public keys that are, in some examples, resistant to quantum-based computing attacks. Various methods are described that request, generate, verify, and use the implicit certificates. In some examples, the system provides an implicit certificate that enables communication between two parties that are identified at the time of certificate generation. In another example, the system provides a certificate that may be used to communicate with a variety of different parties. The implicit certificate generation algorithm yields a public key purportedly bound to U. Confirmation that the public key is bound to U is obtained after use of the corresponding private key. Binding of an entity to its associated public key and accessibility to the private key, are verified as a result of successful key use.

Abstract: A method for data storage, in a system that includes multiple servers, multiple multi-queue storage devices and at least one storage controller that communicate over a network, includes receiving in a server, from an application running on the server, a request to access data belonging to one or more stripes. The stripes are stored on the storage devices and are shared with one or more other servers. In response to the request, the following are performed at least partially in parallel: (i) requesting one or more global locks that prevent the other servers from accessing the stripes, and (ii) reading at least part of the stripes from the storage devices speculatively, irrespective of whether the global locks are granted. Execution of the request is completed upon verifying that the speculatively-read data is valid.

Abstract: Systems and methods in accordance with various embodiments of the present disclosure provide approaches for mapping entries to a cache using a function, such as cyclic redundancy check (CRC). The function can calculate a colored cache index based on a main memory address. The function may cause consecutive address cache indexes to be spread throughout the cache according to the indexes calculated by the function. In some embodiments, each data context may be associated with a different function, enabling different types of packets to be processed while sharing the same cache, reducing evictions of other data contexts and improving performance. Various embodiments can identify a type of packet as the packet is received, and lookup a mapping function based on the type of packet. The function can then be used to lookup the corresponding data context for the packet from the cache, for processing the packet.

Abstract: Technologies are disclosed for storage and retrieval of parameters used in the creation and editing of infrastructure-as-code (IAC) templates. An infrastructure-as-code (“IAC”) template related to desired resources available in a service provider network for configuring a stack of the desired resources in the service provider network is provided. The IAC template includes an identification of a key-value pair associated with resource definitions related to the desired resources and are stored in a data store. Based upon the identification of the key-value pair, a look-up function is used to call a stateless event driven compute service function to query the data store for the resource definitions. Once the resource definitions are received from the data store, based upon the IAC template and the resource definitions, the stack of the desired resources is configured.

Abstract: This disclosure describes techniques and systems for encoding instructions in audio data that, when output on a speaker of a first device in an environment, cause a second device to output content in the environment. In some instances, the audio data has a frequency that is inaudible to users in the environment. Thus, the first device is able to cause the second device to output the content without users in the environment hearing the instructions. In some instances, the first device also outputs content, and the content output by the second device is played at an offset relative to a position of the content output by the first device.

Abstract: Identifying existing orders of non-subscribers that are eligible for subscription-based shipping program features, enrolling the non-subscriber, and instructing modification of the fulfillment of the existing order based on the enrollment is described. A non-subscriber places an order for an item and a fulfillment plan is generated for the order. A determination is made whether the order is eligible for subscription-based shipping based on various factors and if eligible, the non-subscriber may subsequently be notified in a message that if she/he were a subscriber, they would have had their item by now. Analysis associated with the determination may include analysis of various possible fulfillment options that provide various mixes of factors such as inventory location, shipping cost, and available time, for example. If the non-subscriber agrees to become a subscriber, she/he is enrolled as a subscriber and the fulfillment plan for the existing order may be accelerated.

Abstract: Method and apparatus for stress management in a searchable data service. The searchable data service may provide a searchable index to a backend data store, and an interface to build and query the searchable index, that enables client applications to search for and retrieve locators for stored entities in the backend data store. Embodiments of the searchable data service may implement a distributed stress management mechanism that may provide functionality including, but not limited to, the automated monitoring of critical resources, analysis of resource usage, and decisions on and performance of actions to keep resource usage within comfort zones. In one embodiment, in response to usage of a particular resource being detected as out of the comfort zone on a node, an action may be performed to transfer at least part of the resource usage for the local resource to another node that provides a similar resource.

Abstract: A method and system for capturing an image of a portion of an environment including an object of interest and uploading of the image to a service for further image analysis.

Abstract: Systems and methods are provided for retraining a machine learning model to learn a retrained machine learning model. After a computing system receives an execution log of a prediction service and an observed user action, it may create retraining data. From the retraining data, the computing system may learn a retrained machine learning model. The retrained machine learning model can be used to compute future predictions of user actions if it has an improved performance over the original machine learning model.

Abstract: Described is a system for counting stacked items using image analysis. In one implementation, an image of an inventory location with stacked items is obtained and processed to determine the number of items stacked at the inventory location. In some instances, the item closest to the camera that obtains the image may be the only item viewable in the image. Using image analysis, such as depth mapping or Histogram of Oriented Gradients (HOG) algorithms, the distance of the item from the camera and the shelf of the inventory location can be determined. Using this information, and known dimension information for the item, a count of the number of items stacked at an inventory location may be determined.

The coordinator receives a request for dedicated connectivity to data center resources, formatted according to the interface. The coordinator selects a target endpoint router at which to establish a physical link to implement the dedicated connectivity, and transmits a response identifying the target endpoint router and including configuration instructions for setting up a physical link for the dedicated connectivity.

Abstract: Techniques are described for providing a storage service that stores information about large numbers of transactions in a persistent manner, such as with a high degree of reliability, availability and scalability based at least in part on use of a distributed computing and storage system. In some situations, the transaction information storage service stores various information about transactions that each include at least one monetary payment (e.g., a micro-payment) between financial accounts of two or more of numerous users having accounts with one or more entities. The transaction information storage service may be provided by or otherwise affiliated with a merchant, and customers of the merchant may purchase usage of the storage service for programs executed by or otherwise affiliated with the customers, with the storage service available to remote executing programs via a defined API of the storage service, such as a Web services-based API.

Abstract: A database management system provisions a database server that replicates assignments of resource identifiers to resources that are managed by another database server. Based at least in part on assignment of existing sets of identifiers to other database servers, the database management system identifies a set of identifiers that is distinct from these existing sets and assigns this set of identifiers to the provisioned database server. If the database management system detects an event that causes the database server to lose its ability to receive these assignments of identifiers from the other server, the database management system enables the database server to assign identifiers from its assigned set of identifiers.
