Abstract: Some embodiments facilitate high performance packet-processing by enabling one or more processors that perform packet-processing to determine whether to enter an idle state or similar state. As network packets usually arrive or are transmitted in batches, the processors of some embodiments determine that more packets may be coming down a multi-stage pipeline upon receiving a first packet for processing. As a result, the processors may stay awake for a duration of time in anticipation of an incoming packet. Some embodiments keep track of the last packet that entered the first stage of the pipeline and compare that with a packet that the processor just processed in a pipeline stage to determine whether there may be more packets coming that need processing. In some embodiments, a processor may also look at a queue length of a queue associated with an upstream stage to determine whether more packets may be coming.

Abstract: Techniques are described for facilitating interactions between task requesters who have tasks that are available to be performed and task performers who are available to perform tasks, such as via an electronic marketplace acting as an intermediary for task performance. In some situations, the facilitating of the interactions includes automatically matching available tasks to task performer users, such as to automatically generate recommendations for task performer users of available tasks that are appropriate for those task performer users to perform. Such generated task recommendations for task performer users may then be provided to those task performer users in various ways, including via one or more Web pages or electronic communications sent to devices of the task performer users. The task recommendations may be generated in various ways, including based on previous tasks performed by the task performer users and on other prior activities of the task performer users.

Abstract: Usage of shared resources can be managed by enabling users to obtain different types of guarantees at different times for various types and/or levels of resource capacity. A user can select to have an amount or rate of capacity dedicated to that user. A user can also select reserved capacity for at least a portion of the requests, tasks, or program execution for that user, where the user has priority to that capacity but other users can utilize the excess capacity during other periods. Users can alternatively specify to use the excess capacity or other variable, non-guaranteed capacity. The capacity can be for any appropriate functional aspect of a resource, such as computational capacity, throughput, latency, bandwidth, and storage. Users can submit bids for various types and combinations of excess capacity, and winning bids can receive dedicated use of the excess capacity for at least a period of time.

Abstract: A logically centralized system or service, such as a cloud-based content management service, enables intelligent communication between disparate devices. Such communication enables content such as applications and data to be synchronized between various devices, where the synchronization takes into account the capabilities of each device to provide versions and/or formats of that content that are appropriate for each device. A user purchasing an additional device, for example, can have various applications and other content automatically installed or copied over to the additional device, but with versions or formats that take advantage of, and are appropriate for, the capabilities of that additional device. Further, the intelligent communication via a logically centralized service can enable such devices to interact even though those devices might utilize different protocols and/or formats, and might otherwise not be able to communicate or have ever have been tested together.

Abstract: Systems and methods for managing mapping information for objects maintained in a distributed storage system are provided. The distributed storage system can include a keymap subsystem that manages the mapping information according to object keys. Requests for specific object mapping information are directed to specific keymap coordinators within the keymap subsystem. Each keymap coordinator can maintain a cache for caching mapping information maintained at various information sources. To manage the cache, the keymap system can utilize information placeholders that replace previously cached keymap information while a request to modify keymap information is being processed by the information sources. Each keymap coordinator can process subsequently received keymap information read requests in the event an information placeholder is cached as the current cached keymap information.

Abstract: A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computer transmits a request for content from a content provider. The content provider utilizes executable code, such as translation request code, for facilitating request routing utilizing popularity information. The translation request code, may direct a client computing device to request further translation request code and/or translation information. Thereafter, the client issues a DNS query with the translated information including popularity information. The content delivery network service provider can then either resolve the 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 until a DNS nameserver resolves a DNS query from the client computing device.

Abstract: A method of adding a power feed to electrical systems includes coupling a set of input lines to a power source such that the input lines are connected to at least one phase of AC power from the power source, and coupling a set of backfeed lines to an output receptacle in a power distribution unit. The output receptacle may be connected in parallel with at least one other output receptacle that is supplying primary power to systems in the data center. The set of backfeed lines and the set of input lines may be tested to determine a match between a pair of lines in the set of backfeed lines and a pair of lines in the set of input lines. Determining the match may include matching the phase of the pair of backfeed lines with the phase of the pair of input lines.

Abstract: Embodiments of a system and method for evaluating correction submissions with supporting evidence may include, subsequent to a submitter being provided with item description information for an item offered for sale, receiving a correction submission specified by the submitter. The correction submission may specify a proposed modification to an attribute(s) in the item description information. Embodiments may include generating a measure of risk associated with performing the proposed modification to the item description information. Embodiments may also include, based on an evaluation of the measure of risk and one or more risk criteria, generating an indication that specifies whether the proposed modification to the item description information is permitted to be performed. Embodiments may also include receiving information for confirming the validity of the correction submission, which may include an image (e.g., a product image), or a network address (e.g.

Abstract: Customers receive advertisements or “impressions” related to brick and mortar merchants while accessing online content. The merchants or other entities track which impressions correlate with customers coming to a physical store and conducting a transaction (e.g., making a purchase) by comparing transaction information with information about the customer that is provided by the source of online impressions. In one implementation, the merchant creates a hash from the customer's name and account number on a payment card. This hash is compared with a hash from the impression provider that is generated using the same technique. When a match is found, it is inferred that exposure to the online impression caused the customer to make a purchase at the physical store. Merchants may pay the impression providers an advertising or referral fee based on the matches.

Abstract: Techniques for providing a single text field and multiple different types of user input modes for inputting information into the single text field are described herein. In some instances, a user may enter a first portion of text into the text field in a first user input mode before inputting a second portion of text into the field in a second user input mode. The techniques may enforce a first set of rules associated with the first user input mode while the user enters the first portion of text. The techniques may then enforce a second, different set of rules associated with the second user input mode while the user enters the second portion of text. As such, the techniques enable a user to provide two or more different pieces of information into a single text field.

Abstract: Cross Site Request Forgery (CSRF) and other types of fraudulent submission in an electronic environment can be mitigated using state information that typically is already maintained for various users. Each submission requiring authentication includes a state identifier (ID). The state ID is compared to corresponding a state ID submitted in a relatively secure format, such as in a secure token or cookie. If the state ID matches a state ID in the secure token received from the user, and the state ID is valid, the submission is processed. Otherwise an interstitial page, including the state ID and a secure token, is generated to prompt the user to confirm the submission. A subsequent confirmation submission will contain the proper state ID and the new cookie, and can be processed. If no confirmation is received from the user with a valid state ID, the submission is not processed.

Abstract: One or more images of items for an order being processed at processing station of an order fulfillment center may be captured and associated with the order. Alternatively, a short video clip may be captured of the order being packaged. An electronic notification that the order has been processed may be sent to a customer associated with the order. The electronic notification may include a reference to one or more of the captured images or video clips. The customer may use a reference included in the notification to view the captured images. The customer may view captured images to verify that the order has been correctly processed. The captured images may include images of the items being packaged for shipment and may show the shipping address on the package allowing the customer to verify that indeed it is his package in the images.

Abstract: An action submitted via a network may be fulfilled despite the network, or a website accessible via the network, experiencing an error that prevents processing of the action when the action is received. In one example, the user that submitted the action may receive a confirmation page indicating that the action has been received. Transaction data may be retrieved based at least in part on the action and/or the user that submitted the action. Once the transaction data is stored in a queue, the transaction data may be processed either automatically or manually. Subsequently, the action may be fulfilled without the user needing to resubmit the action. Alternatively, the action may be optimistically fulfilled prior to the action being processed.

Abstract: Embodiments of a system and method for identifying and correcting marginal false positives in machine learning models may include, based on reference data that includes pairs of information items and labels indicating whether pairs of information items have a specific relationship, generating a first machine learning model for determining whether pairs of information items have that relationship. Embodiments may include identifying one or more false positive pairs (e.g., a pair of information items that the first machine learning model indicates as having the specific relationship and which are labeled within the reference data as not having that relationship). Embodiments may include selecting identified false positive pairs as candidates for correction.

Abstract: Disclosed are various embodiments for performing cross-domain communication using messenger frames. One or more messenger frames are dynamically generated in response to determining that a message is to be sent from a first frame in one domain to a second frame in another domain in a client. The message is sent from the first frame to the second frame by embedding the message in addresses of the messenger frames. Code executing in the first frame and code executing in the second frame are restricted from direct communication in the client.

Abstract: Widgets or other code modules for applications written in structured languages such as HTML can be tested advantageously by separating the extraction and validation logic. To test the functionality of a widget in response to an action, widget features of interest are identified. Context and feature nodes for these features are extracted from a page tree structure to generate a property vector that is representative of the state of the widget. After performing the action, context nodes for the features are attached to the new page tree for the newly loaded page, and an observed property vector is generated that represents the state of the widget after the action. The previous property vector is used with updated state information to generate an expected property vector. The observed property vector is compared with the expected property vector, and if the vectors match the validation is claimed to be successful.
