Abstract: Disclosed are various embodiments for increasing diversity of search results. A computing device performs a search of items in an electronic catalog to produce a plurality of search results. The electronic catalog is stored in a data store accessible to the computing device. A latent group is identified which includes a most relevant one of a plurality of search results. Each of the search results has a plurality of attributes. Membership in the latent group is determined by similarity of a non-indexed one of the attributes. A relevance score of those search results in the identified latent group other than the most relevant one of the search results is reduced.

Abstract: The deployment and scaling of a network of electronic devices can be improved by utilizing one or more network transpose boxes. Each transpose box can include a number of connectors and a meshing useful for implementing a specific network topology. When connecting devices of different tiers in the network, each device need only be connected to at least one of the connectors on the transpose box. The meshing of the transpose box can cause each device to be connected to any or all of the devices in the other tier as dictated by the network topology. When changing network topologies or scaling the network, additional devices can be added to available connectors on an existing transpose box, or new or additional transpose boxes can be deployed in order to handle the change with minimal cabling effort.

Abstract: A remote browsing and searching process is directed to the generation and management of a remote browse session at a network computing provider. Responsive to a search request, the network computing provider provides search results corresponding to historical content representations associated with content previously requested by the client computing device, or search results corresponding to content representations associated with current content, or to both. The network computing and storage provider may determine the search results based on a navigation path associated with a previous request for content, based on navigation paths of other client computing devices, based on relationships or differences between various versions of content, or based on any number of other factors.

Abstract: Embodiments may include, for each item in a subset of items from a larger group of items, evaluating item description information about that item to identify a respective set of candidate phrases to be evaluated. Embodiments may also include, for each phrase in the sets of candidate phrases, generating multiple component scores based on one or more of the frequency with which that phrase occurs in the item description information for the subset of items and/or the frequency with which that phrase occurs in a corpus of item description information for the overall group of items. Embodiments may also include, for each phrase in the sets of candidate phrases, generating a respective phrase score based on the component scores generated for that phrase. Embodiments may include, based on phrase scores, selecting a subset of phrases from the sets of candidate phrases as being feature phrases for the subset of items.

Abstract: In some implementations, a testing service receives a test execution request for executing test operations on a test target. The testing service may map the test execution request to a particular type of supported test framework from among a plurality of types of supported test frameworks. The testing service may obtain a test package provided by a user that requested the testing, such as from a cloud storage location. The testing service determines a computing capacity for executing the testing and appropriates a plurality of workers in a cloud computing service. The testing service configures the plurality of workers for executing the test operations based on at least one of the test framework, the test execution request or the test package. The testing service provides test execution chunks from the test package to the plurality of workers for executing the testing on the test target.

Abstract: A test environment is created for use in selecting updates for deployment to a programmable execution service (“PES”) application. The test environment is created in one embodiment by replicating a production network and one or more production virtual machine instances executing the PES application. Once the test environment has been created, the test environment is utilized to test and select updates for deployment to the PES application. The updates may be selected by deploying the updates to the test environment and using the test environment to determine whether the deployed updates are compatible with the PES application, permit the PES application to continue to operate performantly, and/or permit the PES application to meet one or more business performance metrics. Once the updates have been selected, the updates may be applied to production virtual machine instances executing the PES application.

Abstract: Various embodiments of a system and method for personalized commands are described. The system and method for personalized commands may include a payment service including a command management component. Such payment service may be responsive to one or more base commands. The command management component may be configured to generate a user interface for specifying personalized commands that correspond to the base commands. The command management component may be configured to generate mapping information from the information received via the user interface. The command management component may be configured to receive one or more messages that may include commands for the payment service, including personalized commands. From the personalized commands, the command management component may be configured to determine a corresponding base commands (e.g., based on the mapping information). Once the base command is determined, the payment service may perform the base command.

Touches on a touch sensor positioned on a front surface provide additional input while also allowing the user to grasp and hold the device.

Abstract: A system, method and computer-readable medium for request routing based on cost information are provided. A client request processing a resource identifier for requested content transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of cost information. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat with the content delivery network service provider's network until a DNS nameserver resolves a DNS query from the client computing device.

Abstract: Requests for content are received, for example, an HTTP request for a web page is received. Each request has a landing context, which may include information about the user sending the request, the request itself, the referrer, or another subject. This information can be found in the requests or external to the requests. The information of the landing context is compared to appropriate triggering criteria. For requests that satisfy the appropriate triggering criteria, a destination is provided based on one or more weighted treatments. The request is directed to the provided destination. The results of the requests are subsequently analyzed and used to adjust the treatments in an automated fashion.
