Abstract: Categorization of data may be performed using rule-based data categorization. Rules may be used to categorize the data into a limited number of categories for a temporary, ad hoc, or updatable process. The rules may be validated to make sure the rules are not ambiguous, contradictory, unattainable, or otherwise ineffective. The rules may include a priority value which may be used as a tie breaker when more than one rule applies to a record. To implement the rules, a lookup flow may be generated to enable rapid or quick traversal of applicable rules for a particular lookup while bypassing at least a portion of the rules. In some embodiments, a record (e.g., an item, etc.) may be categorized during a transaction process to determine a tax classification, a promotion, or another type of classification, which may then be used to complete the transaction.

Abstract: A data center includes an electrical load, a connection to a utility power source, a uninterruptible power supply (UPS), a switching device and a control system. The control system is configured to cause the switching device to discontinue routing electrical power to the electrical loads via the UPS for a given period of time while electrical power is still available to be fed to the electrical loads from the utility power source. Subsequent to the given period of time, the control system cause the switching device to resume routing electrical power to the electrical loads via the UPS.

Abstract: Enhanced graphical user interfaces for transcription of audio and video messages is disclosed. Audio data may be transcribed, and the transcription may include emphasized words and/or punctuation corresponding to emphasis of user speech. Additionally, the transcription may be translated into a second language. A message spoken by a user depicted in one or more images of video data may also be transcribed and provided to one or more devices.

Abstract: A method and apparatus for securing access to a document stored by a document management and collaboration system are disclosed. In the method and apparatus, access credentials pertaining to a document are obtained, whereby the access credentials are usable for authenticating a request to access the document. A message including the access credentials is then sent out-of-band in relation to a notification indicating availability of the document for access. The document management and collaboration system then receives a request to access the document, whereby the request includes the access credentials, and authenticates the request based at least in part on the access credentials.

Abstract: A method for selecting a service endpoint from a plurality of service endpoints in a distributed system of a service provider may include storing processing data for each of the plurality of endpoints. A success rate may be calculated for each of the plurality of service endpoints and based on a number of processed requests from a plurality of received requests. An average latency may be calculated based on latency associated with each of the processed requests. A latency score may be calculated based on a minimum average latency and the average latency. A raw score may be calculated based on the latency score and the success rate. A selection weight may be calculated based on the raw score and a balancing parameter. One of the plurality of endpoints may be selected based on the selection weight.

Abstract: Techniques are provided herein for implementing transparent user interface elements. In at least one embodiment, a user interface comprising a section header element and a section entry element associated with the section header element may be presented. The section header element may have a background that is transparent and the section entry element may be presented as being below the section header element. User input corresponding to a scroll action may be received. The section entry element may be scrolled upward within the user interface based at least in part on the user input. It may be determined that the scrolling causes the section entry element to traverse the section header element. As a result, the background of the section header element may be altered from transparent to translucent and the section entry element may appear as if behind the section header element.

Abstract: Techniques for delivering live streaming content are described by which a streaming heuristic is selected based on the delay between the live and client playheads. For live content for which the delay is short, a low latency streaming heuristic is selected which is designed to handle live content streams for which only a few seconds of content can be buffered. For live content for which the delay is longer, a higher latency streaming heuristic is selected which is designed to handle streams for which the delay is sufficient to build a buffer of content fragments.

Abstract: A compression circuit includes a buffer, a selection circuit, a compare circuit, and a control circuit. The buffer stores uncompressed data. The selection circuit generates a read pointer value to the buffer. The control circuit contains a programmable configuration register. The configuration register stores a depth value for reading uncompressed data from the history buffer. The control circuit generates control signals to the selection circuit to cause the selection circuit to iteratively increment the read pointer value from an initial value to a second value that corresponds to the depth value. Responsive to the second value corresponding to the depth value, the control circuit resets the read pointer value to the initial value. The compare circuit compares input symbols from a data source to uncompressed data from the buffer history to thereby generate output compressed data.

Abstract: Optical fiber communication systems include monitor filters that permit OTDR or other monitoring signals to co-propagate or counter-propagate on link fibers. OTDR measurements are periodically triggered, and acquired OTDR signatures are compared with store signatures to locate faults. The monitor filter can be used in single direction, dual OTDR bidirectional, or signal OTDR bidirectional (loopback) monitoring.

Abstract: A distributed, web-services based storage system. A system may include a web services interface configured to receive, according to a web services protocol, a given client request for access to a given data object, the request including a key value corresponding to the object. The system may also include storage nodes configured to store replicas of the objects, where each replica is accessible via a respective unique locator value, and a keymap instance configured to store a respective keymap entry for each object. For the given object, the respective keymap entry includes the key value and each locator value corresponding to replicas of the object. A coordinator may receive the given client request from the web services interface, responsively access the keymap instance to identify locator values corresponding to the key value and, for a particular locator value, retrieve a corresponding replica from a corresponding storage node.

Abstract: An online analytical processing system may comprise an n-dimensional cube structured using slice-based partitioning in which each slice comprises one or more hierarchies of data points. A region of a hierarchy may be classified according to computational demands associated with the region. A scaling or replication mechanism may be applied to the region based on the computational demands associated with that region.

Abstract: A file system interface receives, from one or more clients, file system operations over a network. In response to receiving a file system operation for a file, a file-object manager calls an object storage interface to store, via an application-level network protocol, a log object indicating the file system operation into a file system log in the object storage system and creates or updates a file object in a file object construction buffer in volatile system memory. To evict the file object, the file-object manager calls the object storage interface to store the file object into a file object store in the object storage system. The file-object manager does not have access to local persistent storage. After power failure, the file-object manager calls the object storage interface to retrieve log objects from the file system log and replays file system operations to restore file objects in the volatile system memory.

Abstract: Methods, systems, and computer-readable media for graphics overlays with virtualized graphics processing are disclosed. A virtual GPU is attached to a virtual compute instance. The virtual compute instance is implemented using a physical compute instance, and the virtual GPU is implemented using a physical GPU accessible to the physical instance over a network. An application is executed on the virtual compute instance. One or more graphics instructions associated with the application are sent to the virtual GPU. The virtual GPU is used to generate graphical output based (at least in part) on execution of the one or more graphics instructions. A graphics overlay comprising one or more additional graphical elements is added to the graphical output based (at least in part) on execution of one or more additional graphics instructions. The one or more additional graphics instructions are not generated by the execution of the application.

Abstract: Certain embodiments of the systems and methods described herein are directed to tagging resources of a remote computing service based on locality. In some embodiments, the locality tags may be used to indicate a locality of the resource and/or to identify resources of the remote computing service based on a specified type of locality (e.g., network, geographic, etc.). A user may receive a listing of resources based on the specified locality, which may allow the user to more effectively or efficiently initiate or execute actions using the remote computing service. In some embodiments, the remote computing service may generate a locality graph using the listing of the resources and may provide services based on the locality graph, such as automatic access control of resources and/or configuration of dynamic alarms associated with the resources.

Abstract: Systems, methods, and computer-readable media are disclosed for pre-rendering content in one or more secondary content buffers to reduce the amount of time required to display the pre-rendered content on a device. The pre-rendered content may be associated with a high probability of being accessed subsequent to content currently being displayed on the device, and may be identified based on the currently displayed content and/or historical device usage data.

Abstract: Throttling for network requests may be implemented. A request processing balance may be provided for processing received network requests for a given period of time. As network requests are received, processing costs may be determined for the network requests. Processing costs may be determined on-the-fly based on processing times, resources consumed, or costs incurred to process the network requests at additional systems, in some embodiments. The request processing balance may be updated according to the determined processing costs of received network requests. Network requests may be throttled based on the current request processing balance. In some embodiments, an estimated processing cost may be determined and compared with the current request processing balance to determine whether to throttle the network requests.

Abstract: An isolated work space is created within a confined area used as an airflow plenum to inhibit the spread of debris and/or contamination. For example, a work area can be formed in an under-floor space of a datacenter. Forming the work area includes erecting an airflow barrier to surround a work area portion of the under-floor space, forming a lower-perimeter seal to seal a bottom edge of the airflow barrier, forming an upper-perimeter seal to seal a top edge of the airflow barrier, operatively connecting a vacuum source with the work area portion, and operating the vacuum source to reduce the air pressure within the work area portion relative to the remaining portion of the under-floor space.

Abstract: Disclosed herein are techniques for maintaining a secure execution environment on a server. In one embodiment, the server includes a bus manager circuit. The bus manager circuit comprises a first bus interface configured to be coupled with a first hardware device of the server, and a second bus interface configured to be coupled with a second hardware device of the sever. The bus manager further includes a control module. Under a first mode of operation, the control module is configured to receive an access request from the first hardware device to access the second hardware device, and responsive to determining not to grant the access request based on a pre-determined access policy, and block at least some of data bits corresponding to the access request from the second bus interface. The control module may also process the access request in a different manner under other modes of operations.

Abstract: A robust digital fingerprint of a file ensures that one able to produce the robust digital fingerprint has possession of the file. A client obtains information that is unpredictable to the client and uses that information to modify the file and generate a robust digital fingerprint from the modified file. A server, with access to the same unpredictable information, verifies the generated robust digital fingerprint. An algorithm for generating the robust digital fingerprint has a property that different representations of the same content will produce matching digital fingerprints.

Abstract: Embodiments presented herein describe an I/O client that switches between generating high-resolution and low-resolution performance data in response to a defined event indicating there is a performance issue with a storage volume. In one embodiment, the I/O client uses one or more event rules that define a condition or threshold for determining whether to generate high-resolution or low-resolution performance data. In one embodiment, the I/O client transmits the performance data to a central monitoring system which can generate a chart plotting the performance data overtime. Because the I/O client may generate the high resolution performance data only when an event rule indicates there is a performance issue, the amount of performance data transmitted to the central monitoring system can be reduced.
