Abstract: Methods and apparatus for interfaces to manage virtual network interface objects. A system may include resource instances and a network interface virtualization coordinator. Responsive to a record creation request, the coordinator creates an interface records that may include an IP address, subnet information and security properties. The coordinator may, in response to a request to attach the record to a resource instance, enable traffic directed to the IP address to flow to the resource instance. In response to a subsequent detach request, the traffic to the IP address may be disabled at the resource instance. The same interface record may be attached to another resource instance in response to another attach request, enabling traffic directed to the IP address to flow to the second resource instance.

Abstract: Disclosed are various embodiments for determining if a requesting client is within a predetermined distance of a location of a trusted client. In one embodiment, a trusted signal having a plurality of trusted signal metrics may be established by the trusted client as being associated with a specified location. The trusted signal may then be rendered to the requesting client to be recorded as a contested signal. In one embodiment, an authentication service may then determine if the contested signal is of an adequate signal quality according a predetermined quality threshold. Assuming the contested signal is of an adequate quality, the authentication service then determines that the requesting client is within a common acoustic environment as the trusted client if the contested signal corresponds to the trusted signal by comparing a plurality of contested signal metrics with a plurality of trusted signal metrics.

Abstract: A host may provide a client-managed hierarchical resource allocation. In some aspects, a host may analyze a computing system including a plurality of computing resources to identify, for various tasks, dependencies between the computing resources. The host may receive a new task to be performed by the computing system. The new task may be associated with a similar task performed by the computing system to enable modeling the new task using dependencies between computing resources which are determined from the similar task. The host may receive an estimate of computing resources required by the new task. The host may then allocate at least a portion of the computing resources to perform the new task based on the estimated workload of the new task and similarities between the new task and the similar task.

Abstract: A probabilistic data structure is generated for efficient query processing using a histogram for unsorted data in a column of a columnar database. A bucket range size is determined for multiples buckets of a histogram of a column in a columnar database table. In at least some embodiments, the histogram may be a height-balanced histogram. A probabilistic data structure is generated to indicate for which particular buckets in the histogram there is a data value stored in the data block. When an indication of a query directed to the column for select data is received, the probabilistic data structure for each of the data blocks storing data for the column may be examined to determine particular ones of the data blocks which do not need to be read in order to service the query for the select data.

Abstract: Technology is described for performing cache data invalidations. The method may include identifying cache update information at a first cache. The cache update information may identify a cache entry (e.g., a trending cache entry). A second cache may be selected to receive the cache update information from the first cache. The cache update information identifying the cache entry may be sent from the first cache to the second cache. For example, the second cache may be populated by adding the trending cache entry into the second cache.

Abstract: Various interfaces and control schemes are provided that enable a user to enter text or select specific elements of an interface based at least in part upon relative motion. In some embodiments, a user can enter text by tilting a device to locate a specific character, and press on a button or specified area of a device to select that character. In other embodiments, a user can select a character by looking at a character and performing a selection action, a user device able to determine the character by tracking a gaze direction of the user. Any relative movement of a device and/or a user can be used as input, allowing for one-handed or even hands-free entrance of text or other selection of elements of a graphical user interface.

Abstract: Multiple versions of a service can be supported by taking advantage of the fact that version information can be included in any received request. Using the version information, an appropriate template can be determined up front to be used for the response. In instance of the template can be filled in using appropriate data sources, as may be specified using metadata in the template itself. Information can be processed in parallel, respecting any data dependencies specified by the template metadata. Once the instance of the template is filled, the response can be finalized and sent to the source of the request.

Abstract: Technology is described for personalizing a product placement in content. The method may include identifying a dynamic location in the content available for the product placement. A user profile may also be identified. The product placement may be selected based on the dynamic location identified in the content and the user profile. The product placement for the dynamic location identified in the content may then be provided.

Abstract: Systems and methods are described for enabling users to model security resources and user access keys as resources in a template language. The template can be used to create and update a stack of resources that will provide a network-accessible service. The security resources and access keys can be referred to in the template during both stack creation process and the stack update process. The security resources can include users, groups and policies. Additionally, users can refer to access keys in the template as dynamic parameters without any need to refer to the access keys in plaintext. The system securely stores access keys within the system and allows for templates to refer to them once defined. These key references can then be passed within a template to resources that need them as well as passing them on securely to resources like server instances through the use of the user-data field.

Abstract: Methods and apparatus for distributed Internet backbone DDOS (distributed denial of service) mitigation via transit providers. A provider network may include a data center and a remote point of presence (RPOP) linked to the data center by private backbone links. The data center may include servers, a traffic analyzer and a routing information generator. The traffic analyzer determines a target address to which a pattern of traffic matching a profile is detected. The routing information generator may generate new routing information for the target address that avoids the use of the backbone, and provide the information to an IP transit provider. The IP transit provider propagates the new routing information to the RPOP, which directs subsequent traffic to the target address over a path that excludes the backbone.

Abstract: A system and method of dynamically generating software is provided. Applications are created in a set of workflow models which are tested in an interpretive test environment. The models are stored in a versioning repository and code generation templates created for the models. Source code is generated and compiled for the application. Modifications to the models are tested and incorporated into a modified version of the application after subsequent testing of the model and the modified, compiled application. The modified version of the application is returned to the test environment where it becomes the basis for testing future modifications.

Abstract: Disclosed herein are systems, devices, and techniques for using collective intelligence to improve a customer's experience when using network-based services. Data generated as a byproduct of one or more customer interactions with the network-based service may be repeatedly gathered, optionally stored, and analyzed to generate collective intelligence information. This collective intelligence information may be compared to various assessed parameters associated with a characteristic (i.e., a type and/or a configuration) of a computer resource(s), parameters associated with a state of the network-based service provider environment, and/or a customer experience criterion specified by the customer.

Abstract: Disclosed are various embodiments of adjusting a search result user interface when a foreign language search query is detected. A search query associated with a search request is obtained. A language of the search query is identified. An alternative search result user interface is generated when the language varies from an expected language. Additionally, an alternative search query can be generated that is based at least in part upon the originally submitted search query.

Abstract: A user can provide input to a computing device by moving a feature or object, such as a user's finger, within a field of view of at least one imaging element of the computing device. In order to ensure an accuracy of the determined input, the computing device can also attempt to determine a point of view of the user, such as by determining a relative position of the user's face or eyes. By determining a three-dimensional position of a feature and the user's point of view, a three-dimensional vector or other directional information can be determined whereby the intersection of that vector with the computing device indicates an intended location of input corresponding to the feature from the user's point of view.
