Abstract: Bookmark services are provided in which user-selected bookmarks to favorite web pages are stored. In response to receiving a request for a web page from a particular user, the website operator may make a call to the bookmark service to obtain bookmarks that were previously selected by that user. The bookmark service forwards the bookmarks for the user to the website operator, and the website operator includes these bookmarks within the web page that is rendered to the user. Since the bookmarks are stored remotely at a bookmark service, the bookmarks may be available to the user regardless of the electronic device or web browser that is used to request a web page. The bookmarks that are rendered on the web page may also include recommended bookmarks to web pages that are deemed as possibly being of interest to a particular user.

Abstract: Methods and systems for analyzing camera lenses and presenting information regarding camera lenses performance are described.

Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to select and manipulate objects within a scene, and to modify an object by adding or removing accessories from the object or otherwise customizing the object according to the user's preferences or desires. The RVE system may also provide an interface or interfaces via which the user can obtain additional information for the object, customize the object, be given a price or price(s) for the object as customized, and purchase the object as specified if desired.

Abstract: Systems and methods for a device-to-device communications mode are described. When two user equipment are within proximity of each other and other requirements are met, the user equipment are configured by their associated nodes to enter a device-to-device communication mode. In that mode, the user equipment receives messages from the other user equipment without the messages traversing the core network between their associated nodes.

Abstract: A block-based storage system may implement dynamic durability adjustment for page cache write logging. A rate of incoming write requests for data volumes maintained at a storage node may be monitored. Based, at least in part, on the rate of incoming write requests, a dynamic modification to a durability property for a data volume may be made, such as enabling page cache write logging the data volume or disabling write logging for the data volume. When incoming write requests are received, a determination may be made as to whether page cache write logging for a particular data volume is enabled. For write requests with disabled page cache write logging, the page cache may be updated and the write request may be acknowledged without storing a log record describing the update in a page cache write log.

Abstract: A block-based storage system may implement page cache write logging. Write requests for a data volume maintained at a storage node may be received at a storage node. A page cache for may be updated in accordance with the request. A log record describing the page cache update may be stored in a page cache write log maintained in a persistent storage device. Once the write request is performed in the page cache and recorded in a log record in the page cache write log, the write request may be acknowledged. Upon recovery from a system failure where data in the page cache is lost, log records in the page cache write log may be replayed to restore to the page cache a state of the page cache prior to the system failure.

Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to discover, select, explore, and manipulate objects within the modeled worlds used to generate video content. The RVE system may implement methods that allow users to view and explore in more detail the features, components, and/or accessories of selected objects that are being manipulated and explored. The RVE system may also implement methods that allow users to interact with interfaces of selected objects or interfaces of components of selected objects.

Abstract: A system and method for profile-based cache management is disclosed. A cache management service can obtain a plurality of requests for network resource and corresponding responses, group the requests based, at least in part, on various criterion or technique, determine and cache content parts of the responses corresponding to each group of requests. Cache profiles corresponding to each group of requests and identifying corresponding cached content parts can be built, maintained or updated by the cache management service. A subsequent request for network resource can be matched to one or more cache profiles for retrieval of applicable cached content and for generation of a partial response to the request therefrom. Non-cached content or updates to cached content can be further retrieved for generation of updating data to the partial response, and thus completing a full response to the request for network resource.

Abstract: Systems and methods for providing object versioning in a storage system may support the logical deletion of stored objects through the use of delete marker objects. In response to a delete operation specifying a key, but not a version identifier, the storage system may create a delete marker object that is stored as the latest object version of the key. In response to performing a subsequent mutating operation, or at pre-determined time intervals, the storage system may perform a local and/or a global analysis of the delete marker objects stored in the system (and/or metadata associated with those delete marker objects) to determine whether any of them are no longer needed to ensure correct operation of the system. The analysis may apply one or more reap conditions to delete marker objects and/or metadata to identify extraneous delete marker objects, removing those that meet one or more reap conditions from storage.

Abstract: A block-based storage system may implement reducing durability state for a data volume. A determination may be made that storage node replicating write requests for a data volume is unavailable. In response, subsequent write requests may be processed according to a reduced durability state for the data volume such that replication for the data volume may be disabled for the storage node. Write requests may then be completed at a fewer number of storage nodes prior to acknowledging the write request as complete. Durability state for the data volume may be increase in various embodiments. A storage node may be identified and replication operations may be performed to synchronize the current data volume at the storage node with a replica of the data volume maintained at the identified storage node.

Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, and explore 2D or 3D modeled worlds of scenes in a video. The system may leverage network-based computation resources to render and stream new video content from the models to clients with low latency. A user may pause a video, step into a scene, and interactively change viewing positions and angles in the model to move through or explore the scene. The user may resume playback of the recorded video when done exploring the scene. Thus, rather than just viewing a pre-rendered scene in a movie from a pre-determined perspective, a user may step into and explore the scene from different angles, and may wander around the scene at will within the scope of the model to discover parts of the scene that are not visible in the original video.

Abstract: Methods and apparatus for client-allocatable bandwidth pools are disclosed. A system includes a plurality of resources of a provider network and a resource manager. In response to a determination to accept a bandwidth pool creation request from a client for a resource group, where the resource group comprises a plurality of resources allocated to the client, the resource manager stores an indication of a total network traffic rate limit of the resource group. In response to a bandwidth allocation request from the client to allocate a specified portion of the total network traffic rate limit to a particular resource of the resource group, the resource manager initiates one or more configuration changes to allow network transmissions within one or more network links of the provider network accessible from the particular resource at a rate up to the specified portion.

Abstract: A real-time video targeting (RVT) system may leverage network-based computation resources and services, available 2D or 3D model data, and available viewer information to dynamically personalize content of, or add personalized content to, video for particular viewers or viewer groups. When playing back pre-recorded video to viewers, at least some objects or other content in at least some of the scenes of the video may be replaced with objects or content targeted at particular viewers or groups according to profiles or preferences of the viewers or groups. Since the video is being rendered and streamed to different viewers or groups in real-time by the network-based computation resources and services, any given scene of a video may be modified and viewed in many different ways by different viewers or groups based on the particular viewers' or groups' profiles.

Abstract: A real-time video exploration (RVE) system that allows users to pause a pre-recorded video (e.g., a movie) and change viewing positions and angles of one or more scenes. The RVE system may also allow users to select, manipulate, and modify objects within one or more scenes. The RVE system may render new video of the scenes and stream the new video to the user's client device. Using the RVE system, a user may create modified versions of one or more scenes to replace original scenes in a video to thus create a modified version of the video. The RVE system may allow the user to record the modified version of the video, and may allow the user to share the modified version of the video with other viewers.

Abstract: The estimated rate of work requests expected during a time period at a first block storage device, implemented at a particular server of a storage service, exceeds a provisioned rate of the first device. At a client-side component of the storage service, a different storage server is identified, at which the rate of work requests directed during the time period to a second block storage device is anticipated to be less than the provisioned rate of the second device. At least one admission control parameter of the first device is modified to enable the first storage server to accept work requests at a rate that exceeds the provisioned rate of the first device.

Abstract: Technologies are described herein for use in identifying and resolving software issues. One or more corrective actions may be identified and taken that are based upon the similarity between an unresolved issue and one or more resolved issues and/or upon the similarity between code changes made to resolve similar previously resolved issues. A version control graph might also be utilized to determine if a change made to resolve an issue in one branch of a software component is applicable to another branch of the software component. The version control graph might also be utilized to compute the relevance of an entry in an issue tracking system for an issue at a point in time after the entry is created in the issue tracking system.

Abstract: The values of various operating and/or configuration parameters of a data environment are managed using a set of self-service Web services and interfaces of a separate control environment. A customer can submit a Web services call into an externally-facing application programming interface (API) or other such externally-facing interface of the control environment. The API receiving the call, as well as information extracted from the call, can be used to determine appropriate adjustments to be performed in the data environment. A workflow can be instantiated that includes tasks used to validate and/or apply the adjustments to the target resources, such as databases, data instances, data stores, instance classes, etc. Various real-time functions such as monitoring and auto-scaling also can be performed via the control plane.

Abstract: Various embodiments of a method and system for determining sets of variant items are described. Various embodiments may include a system configured to generate multiple item pairs each corresponding to a particular item and another item determined to be similar to the particular item. For the particular item and the other item, each item pair may include a respective sequence of text strings (e.g., a title). For each item pair, the system may perform a corresponding text alignment and determine one or more misalignments of the item pair. The system may also assign a similarity score to each item pair; the similarity score may be dependent on the misalignment(s) determined for the particular item pair. Based on each aligned item pair and the similarity score assigned to that aligned item pair, the system may generate an indication specifying that each of a set of items are variants of each other.
