Abstract: Requests are pre-generated to include a cryptographic key to be used in fulfilling the requests. The requests may be encoded in uniform resource locators and may include authentication information to enable a service provider to whom the requests are submitted to determine whether the requests are authorized. The requests may be passed to various entities who can then submit the requests to the service provider. The service provider, upon receipt of a request, can verify the authentication information and fulfill the request using a cryptographic key encoded in the request.

Abstract: Monitoring data can be sent, received, stored, and accessed with zero setup. Customers can send monitoring data to be stored without the customers having to perform any setup ahead-of-time, such as arbitrary lists of key-value pairs. Customers can perform zero setup pivot queries using stored monitoring data. For example, users can perform pivot queries using any available stored information, such as available metric types and dimensions, without any setup needed ahead-of-time.

Abstract: A network-based services platform is configured to receive an application template that specifies characteristics of desired network-accessible service components for use by a network-based application.

Abstract: Technologies are disclosed herein for generating and utilizing machine-learning generated classifiers configured to identify document relationships. Manually-generated data is captured that indicates if documents in a document corpus have a relationship with one another, such as duplicates or variations. A determination may then be made as to whether a classifier is to be generated based on the duplicate decision data. If a classifier is to be generated, machine learning may be performed using training documents from the document corpus and the duplicate decision data to generate a classifier. The machine-learning generated classifier may then be utilized in a production environment to determine whether a new document is a duplicate of documents in the document corpus and/or to identify other relationships between documents in the document corpus, such as documents that are similar or are variations of one another.

The first component has access to an alternate communication channel available only to a subset of components of the service. Using the alternate communication channel, the first component reaches a local workload agreement with a second component, in accordance with which at least some service requests of the first component or the second component are fulfilled using the alternate communication channel.

Abstract: Techniques and systems described herein locate possibly-significant portions of electronic documents. In some examples, gaze movements, e.g., of users' eyes, are tracked while the users read a formatted version of an electronic document. The gaze movement may be analyzed to determine if a reading interruption occurs (e.g., a reading pause or irregularity in a regular reading rate for the user). The reading interruption may occur when the user, while reading, encounters or notices a problem or point of interest in the text. A reading location associated with the reading interruption may be determined in text that is currently displayed. The reading location may be mapped to a location in a standard version of the document. The location may be reported to a centralized entity where statistical analysis can be performed to determine if there is a problem in the document.

The UAV may be removed from the conveyance device in the event the UAV fails at least one of the structural integrity test or the functionality test. A package may be loaded into a compartment of the UAV in the event the UAV passes the structural integrity test and the functionality test.

Abstract: Recommendations of items may be provided to a customer who purchases items from an online marketplace on behalf of a user account based on the interactions of the customer with the marketplace or with one or more external resources, such as a social network account affiliated with the customer. For example, systems and methods may utilize such interactions to determine which of the purchases of items on behalf of the user account are affiliated with the customer, and which may be affiliated with one or more other individuals. Similarly, the systems and methods may also identify recommendations for customers who have purchased items for delivery to a destination based on other items that have been delivered to the destination, and may further determine when a customer has purchased an item for a recipient who has already received the item from another customer.

Abstract: Technologies are described herein for facilitating discovery of items added to electronic wish lists. Real-time messages that identify items that have been recently added to wish lists are received from a wish list service. A stream of real-time data is generated from the messages that identifies the items added to the wish lists. A network application programming interface (API) is exposed for providing the stream to clients. A client may obtain the stream from the network API and utilize the stream to generate a visualization of the items added to the wish lists in real-time. Through functionality provided by the API, the stream may also be filtered and searched. Trend data may also be obtained through the API that identifies items that have been added to the wish lists most frequently over a period of time.
