Abstract: Disclosed is an improved approach to integrate distributed applications into an XA transaction. A transaction manager library is integrated into a distributed application, where the transaction manager library provides the benefit of implementing optimizations for the XA transaction, as well as minimizing or eliminating the need to create custom software code to make the application operable with the transaction manager for the XA transaction.

Abstract: A technique efficiently migrates a live virtual disk (vdisk) across storage containers of a cluster having a plurality of nodes deployed in a virtualization environment. Each node is embodied as a physical computer with hardware resources, such as processor, memory, network and storage resources, that are virtualized to provide support for one or more user virtual machines (UVM) executing on the node. The storage resources include storage devices embodied as a storage pool that is logically segmented into the storage containers configured to store one or more vdisks. The storage containers include a source container having associated storage policies and a destination container having different (new) storage policies.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a wireless device receives one or more radio frequency (RF) signals from a transmitter device, displays a first arrow and a second arrow on a user interface of the wireless device, a direction of the first arrow representing a first angle-of-arrival (AoA) estimate of the one or more RF signals, and a direction of the second arrow representing a mirror AoA estimate of the first AoA estimate, and displays one or more notifications on the user interface instructing a user of the wireless device to move the wireless device until the direction of the first arrow is aligned with the direction of the second arrow.

Abstract: In accordance with some aspects of the present disclosure, a non-transitory computer readable medium is disclosed. In some embodiments, the non-transitory computer readable medium includes instructions that, when executed by a processor, cause the processor to receive, from a workload hosted on a host of a cluster, first I/O traffic programmed according to a first I/O traffic protocol supported by a cluster-wide storage fabric exposed to the workload as being hosted on the same host. In some embodiments, the workload is recovered by a hypervisor hosted on the same host. In some embodiments, the non-transitory computer readable medium includes the instructions that, when executed by the processor, cause the processor to adapt the first I/O traffic to generate second I/O traffic programmed according to a second I/O traffic protocol supported by a repository external to the storage fabric and forward the second I/O traffic to the repository.

Abstract: Snapshot or point-in-time image functionality improves the use of object-based datastores. An example system includes an object-based datastore and a metadata datastore associated with the object-based datastore. Instances of the metadata datastore each identify the distributed data blocks that respectively store the objects included in the object-based datastore. An instance of the metadata datastore is used as a snapshot image of a set of objects of the object-based datastore based on identifying the distributed data blocks that were mapped to the set of objects during a point in time. A different instance of the metadata datastore is dynamically updated to reflect present mappings of distributed data blocks to objects in the object-based datastore. Different instances of the metadata datastore are used to read objects from previous timepoints, restore the object-based datastore to a previous snapshot image, enable intelligent deletion of objects of the object-based data store, and more.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed that decode purchase data using an image. An example apparatus includes processor circuitry to execute machine readable instructions to at least crop an image of a receipt based on detected regions of interest, apply a first mask to a first cropped image to generate first bounding boxes corresponding to rows of the receipt, apply a second mask to a second cropped image to generate second bounding boxes corresponding to columns of the receipt, generate a structure of the receipt by mapping words detected by an optical character recognition engine to corresponding first bounding boxes and second bounding boxes based on a mapping criterion, classify the second bounding boxes by identifying an expression of interest in ones of the second bounding boxes, and generate purchase information by extracting text of interest from the structured receipt based on the classifications.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed that decode purchase data using an image. An example apparatus includes a dictionary including associated product descriptions and barcodes, interface circuitry, and processing circuitry to execute machine readable instructions to obtain purchase details and barcodes corresponding to a receipt, the purchase details including receipt product descriptions, generate a search query that includes a first receipt product description of the receipt product descriptions, a list of barcodes corresponding to the barcodes, and a store identifier associated with the receipt, execute a search against the dictionary using the search query to identify a barcode from the list of barcodes that corresponds to the first receipt product description, and in response to identifying the barcode that corresponds to the first receipt product description, associating the barcode and the first receipt product description and adding the association to the dictionary.

Abstract: A messaging service is disclosed that provides access to data center event data for physical infrastructure assets via dynamically configurable custom tags defined by customers. For example, a network services exchange provider or co-location provider deploys a data center monitoring system that monitors physical infrastructure assets that enable system operation within a data center for events. The system implements an API which applies custom tags defined by customers to the assets, wherein each custom tag defines attributes of the assets. The system receives subscription requests that describe events and custom tags applied to the assets. The data center infrastructure monitoring system publishes a subscription of event data related to the events for the assets to which the custom tags are applied. Further, a feed manager receives updates to asset equipment and changes to metadata describing the assets and automatically updates the subscription to account for the changes.

Abstract: Methods, systems, and programs are presented for managing a storage device memory. One method includes an operation for receiving a request to pin a volume stored in the storage device. The device includes disk storage and a solid state drive (SSD) cache, where pinned volumes in the storage device have all active volume data in the SSD cache. Further, the method includes an operation for determining the maximum amount of pinnable space in the SSD cache, the maximum amount of pinnable space being calculated based on the sizes of the disk storage and the SSD cache. Further, the method includes operations for determining the available pinning space, which is the maximum amount of pinnable space minus the current amount of pinned data in the SSD cache, and for granting the request to pin the volume when the available pinning space is greater than or equal to a size of the volume.

Abstract: Ad segments on a Web page are filled with ads that are served by a service provider operating between a user computer and publisher on one end and multiple ad serving entities on the other. The service provider implements a bidding process for the ad segment. The winning ad serving entity (DSP, ATD, advertiser, etc.) has its ad delivered to the user browser by the service provider where it is displayed in the Web page. The floor e-CPM for the ad segment is determined by the publisher using data related to the user (demographic, geographic, socio-economic, etc.), information on the ad segment (e.g., location on page), and relationships the publisher (e.g., a DSP having a relationship with the publisher may be offered a lower e-CPM). The service provider provides tools and highly granular information for the publisher in order to create an appropriate floor e-CPM for the ad segment.
