Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.

Abstract: A system for storing data includes a rack, one or more data storage modules coupled to the rack, and one or more data control modules coupled to the rack. The data storage modules may include a chassis, two or more backplanes coupled to the chassis, and one or more mass storage devices (for example, hard disk drives) coupled to the backplanes. The data control modules may access the mass storage devices in the data storage modules.

Abstract: Recommendations can be generated even in situations where sufficient user information is unavailable for providing personalized recommendations. Instead of generating recommendations for an item based on item type or category, a relation graph can be consulted that enables other items to be recommended that are related to the item in some way, which may be independent of the type or category of item. For example, images of models, celebrities, or everyday people wearing items of clothing, jewelry, handbags, shoes, and other such items can be received and analyzed to recognize those items and cause them to be linked in the relation graph. When generating recommendations or selecting advertisements, the relation graph can be consulted to recommend products that other people have obtained with the item from any of a number of sources, such that the recommendations may be more valuable to the user.

Abstract: Disclosed are various embodiments that involve selecting supplemental content to be included with search results in a network page. At least one search result is generated by executing a search based at least in part on relevance to a search query. Supplemental content is selected based at least in part upon relevance to the search query without regard to the at least one search result. A subset of the supplemental content is selected in response to determining that the subset is permitted to be presented together in a search results page as defined by at least one compatibility rule. The search results page is generated to include the subset of the supplemental content and the search results.

Abstract: A configurable sponge function engine. The configurable engine includes a state register having bitrate and capacity sections, each having a variable size, where a sum of the bitrate and capacity sizes is fixed. A controller generates a bitrate size indication. A configurable message processor receives an input message from an input bus, receives the size indication, fragments the input message into fragmented blocks of a size specified by the size indication, and converts the blocks to a bus width of the bitrate and capacity sizes. An iterative calculator receives the blocks, performs iterative processing operations on the blocks, and stores a result of each operation in the state register overwriting a previous register value. An output adaptor receives a value stored in the state register after the block corresponding to the end of the input message is processed and outputs the register value converted to have an output bus width.

Abstract: Certain embodiments herein relate to attributing or associating a user's actions with respect to web page content to the multivariate test parameters. For example, a user's purchase of a product after clicking on an ad in the web page content may be attributed to multivariate test parameters corresponding to the placement of the ad, the size of the ad image, whether a border is placed around the ad, any number of attributes associated with the ad, the content in which the ad is placed, etc. In certain embodiments, a user's actions may occur at a device that is separate from the publisher device. Techniques described herein may attribute or associate such actions with a publisher's web page content such that publishers may be made aware of the effectiveness of the placement, layout, orientation, etc., of their web page content based on how users reacted to such attributes.

Abstract: A hosted analytics system may be integrated with transactional data systems and additional data sources such real-time systems and log files. A data processing pipeline may transform data on arrival for incorporation into an n-dimensional cube. Correlation between patterns of events in transactional data may be identified. Upon arrival, new data may be transformed and incorporated into the n-dimensional cube. Similarity between the new data and a previously identified correlation may be determined and flagged.

Abstract: Devices, systems and methods are disclosed for creating a self-organized time-synchronization network, enabling accurate synchronization. For example, multiple devices may wirelessly broadcast and receive beacon signals and self-organize into an ad hoc network. The wireless ad hoc network may be optimized as individual devices choose new connections to reduce a number of hops to a source device. Individual devices may include a counter that may increment continuously for timing purposes, and counters may be synchronized between connected devices. For example, a local device may adjust contents of a local counter on the local device based on a drift between the local counter and a remote counter on a remote device. Thus, counters between connected devices may be synchronized, beginning at the source device and propagating through the ad hoc network. Based on the synchronization, the devices may offer additional functionality and/or more sophisticated applications.

Abstract: A client and server negotiate a secure communication channel using a pre-shared key where the server, at the time the negotiation initiates, lacks access to the pre-shared key. The server obtains the pre-shared key from another server that shares a secret with the client. A digital signature or other authentication information generated by the client may be used to enable the other server to determine whether to provide the pre-shared key.

Abstract: A virtualization management component of a particular host at a virtualized computing determines that a packet duplication phase of a migration of a virtual machine from a source host to the particular host has begun. The virtualization management component detects that a migrated version of the virtual machine, instantiated at the particular virtualization host, has generated a baseline packet directed to a destination address. The virtualization management component sends a first encapsulation packet comprising the baseline packet to an encapsulation intermediary associated with the destination address. The virtualization management component sends a second encapsulation packet comprising the baseline packet to the source virtualization host, with a directive to forward the second encapsulation packet to the encapsulation intermediary.

Abstract: Techniques are disclosed for a device that presents a mass storage device to a computing environment, and which stores data written to the device by the computer in a network storage service. The device also presents files stored in the network storage service to the computer as though those files were stored on a mass storage device.

Abstract: Inventory management systems and related methods employ radio frequency based tracking of a worker's hands to monitor performance of inventory tasks. An inventory management system includes inventory bins, a user-wearable unit configured to be worn in proximity to a user's hand, fixed RF antennas configured to transmit at least one RF interrogation signal and receive at least one RF response signal, a RF transceiver operatively coupled with the fixed RF antennas, and a management module operatively coupled with the RF transceiver. The user-wearable unit includes an RF transceiver configured to transmit RF response signals in response to reception of the at least one RF interrogation signal. The management module is configured to process signals generated by the RF transceiver to track locations of the user-wearable unit and identify an inventory bin based on proximity of the user-wearable unit to the identified inventory bin to monitor performance of an inventory system task.

Abstract: A computing resource monitoring service receives a plurality of measurements for a metric associated with an auto-scale group. Each measurement is associated with metadata for the measurement, which specifies attributes for the measurement. The computing resource monitoring service determines, for each measurement and based at least in part on the metadata, a fully qualified metric identifier for the measurement. The service partitions the plurality of measurements into a plurality of logical partitions associated with one or more in-memory datastores. The service transmits the measurements from the plurality of logical partitions to the one or more datastores for storage of the measurements. These measurements are provided to one or more computing resource managers for the auto-scale group to enable automatic scaling of computing resources of the group based at least in part on the measurements.

Abstract: A computing resource monitoring service receives a request to store a measurement for a metric associated with a computing resource. The request includes the measurement itself and metadata for the measurement, which specifies attributes of the measurement. Based at least in part on the metadata, the computing resource monitoring service generates a fully qualified metric identifier and, using the identifier, selects a logical partition for placement of the measurement. From the logical partition, the computing resource monitoring service transmits the measurement to an aggregator sub-system comprising one or more in-memory datastores. The computing resource monitoring service stores the measurement in an in-memory datastore within the aggregator sub-system.

Abstract: A localization service may be provided to manage distribution of content including text overlays according to language codes. In some examples, the language codes include regional identifiers and language identifiers. The localization service may provide the content including translated text overlays for reproduction by client devices in accordance with descriptive data associated with the images. In some examples, the descriptive data may describe the text overlays, placement of the text overlays with respect to the content, and characteristics of the text overlays.

Abstract: Client-side endpoint configuration can be accomplished by allowing a client to include as part of an API request, a desired endpoint for subsequent notifications from a server. The endpoint can be an endpoint identifier, such as a Uniform Resource Identifier (URI) or a domain name. When a web service receives the API request from a client device, the web service can generate a response to the request and send the response to the endpoint identified in the request. The API request can asynchronously communicate with the client device whenever the response is completed.

Abstract: A method for communicating messages between a service and a virtual machine instance may include receiving a message from a service. The message includes a target instance identification of at least one virtual machine instance (VMI) to receive the message. A notification of the message and the target instance identification is stored in a message queue for each of a plurality of host servers associated with a plurality of VMIs. The message is stored in a message store without storing at least a portion of the message in the message queue. A request for undelivered messages is received from a VMI associated with a customer account. In response to the request, it is determined that a local cache contains an indication that the message is undelivered, where the local cache is within at least one of the plurality of host server computers associated with the VMI sending the request.

Abstract: A device can display content on a page associated with a dimension. A user can adjust an orientation of the device to adjust a displayed orientation of the page, enabling pages for additional dimensions to be displayed. A user can select one of these dimensions, and adjust an orientation of the device to enable the user to access content for the selected dimension. The change in orientation can be a tilt or flick of the device in a first direction to select a dimension, and then a user could tilt or flick the device in another direction to view pages, sub-dimensions, or other groupings of content among that dimension. Such an approach can enable a user to quickly locate content corresponding to a sub-dimension without having to scroll down a long page of content or otherwise manually navigate to specific content.

Abstract: Organizations maintain and generate large amounts of documentation and entities of these organizations often need to collaborate on generating and reviewing this information. There is a need to maintain and store this documentation remotely in such a way that the entities of these organizations may collaborate with each other. To ensure that entities of the organization can collaborate on documents, a document annotation service is described that converts a text-based document, such as a word processing document, to a fixed-layout document, such as a coordinate-based document. Annotations can be received on the fixed-layout document. The annotations can then be mapped to the text-based document and downloaded to a user for viewing.

Abstract: An application program may be analyzed to identify candidate classes or methods that may be executed using a remote computing node. Candidate classes or methods may be translocated to the remote computing node based on performance characteristics of the device on which the application program is running, the environment in which the device operates, and on the performance and availability of the remote computing node. An application program publisher may be assigned instances of virtual machines that may be dedicated to hosting translocated classes and methods.
