Abstract: At a logging service, a representation of a transaction requested by a client is received. The transaction includes at least a first write operation directed to a data object at a first data store. Based at least in part on the contents of the representation and contents of a persistent log of the logging service, a determination is made that the requested transaction is to be committed. A log record corresponding to the first write operation is inserted into the persistent log. The first write is propagated to the first data store after the record has been inserted in the persistent log.

Abstract: A computer-implemented method and corresponding system automate lawn service price estimation and scheduling. The method determines at least one physical feature of the topography. The topography is associated with a received physical address of a residence. The received address identifies a physical location associated with the topography. The method estimates parameters to perform a lawn service at the residence based on the at least one physical feature determined. The estimating employs machine learning. The method computes a cost estimate for the lawn service at the residence, automatically, based on the parameters estimated. The method computes a price estimate and outputs the price estimate computed to an electronic device. The automated lawn service price estimation enables a lawn service professional to provide price estimates to a customer, automatically, without having to travel to the residence to observe and perform physical measurements of the topography.

The network node includes processing circuitry configured to: modify at least one function of at least one carrier in a frequency band edge of the unlicensed frequency band where the frequency band edge being located, in a frequency domain, in a non-transmission portion of a spectrum mask that is configured to reduce leakage into an adjacent frequency band, and perform a communication function using the at least one carrier having the modified at least one function.

Abstract: A method displays a chart including visual marks representing a dataset. The chart is based on content of displayed shelf regions, each determining a respective characteristic of the visual marks. The method generates a visual analytic object by applying a first analytic operation to the dataset, and displays the visual analytic object over the chart. The method detects user input to select the displayed visual analytic object and place an icon representing the visual analytic object onto a first shelf region. The first shelf region defines a first characteristic of the visual marks. In response to the user input, the method updates content of the first shelf region to specify association with the first analytic operation and updates the first characteristic of the visual marks in the chart based on values of the set of data represented by the visual marks relative to values computed by the first analytic operation.

Abstract: Techniques are disclosed for efficient utilization worker threads in a workflow-as-a-service (WFaaS) environment. A client device may request a workflow for execution by the client device. The client device may receive the requested workflow and initialize a set of worker threads to execute the workflow and a set of heartbeater threads to monitor the set of worker threads. Upon receiving an indication of a processing delay, the client device may capture the state of the workflow, suspend execution of the workflow, and store the workflow in a temporary queue. While the processing delay persists, the client device may use the set of worker threads to execute other tasks. When the processing delay terminates, the client device may resume execution of the workflow.

The producer resource instance initiates authentication operations for the service, including at least one authentication operation based on the IP address of the interface record.

Abstract: Resource access credential security is improved by providing authentication tools and techniques which do not rely on embedment of credentials in the source code or configuration files of programs that use the credentials to access secured resources. A program under development in a development tool determines through the operation of authentication code that it is under development and that a developer identity is to be used to obtain access credentials, instead of using an identity of the program itself as occurs when the program is not under development. The development tool may be stand-alone, or may be in an integrated development environment, and may be extensible or not. The program may be an application, a web service, or other software, and may be deployed to a cloud or other networked environment. Authentication may be based on a selected developer identity or selected account or other subscriber data.

Abstract: An inductive position detection configuration for stylus position measurement in a scanning probe comprises a stylus position detection portion arranged along a central axis in the probe. The stylus position detection portion includes a field generating coil configuration and top and bottom axial and rotary sensing coil configurations. The field generating coil configuration generates a changing magnetic flux, and coil signals indicate conductive disruptor element and/or stylus positions. A field generating coil coupling and crosstalk reducing configuration couples signal processing and control circuitry to the field generating coil configuration to provide a coil drive signal, and is configured to reduce crosstalk that would otherwise occur if the field generating coil configuration were directly connected to the signal processing and control circuitry without the field generating coil coupling and crosstalk reducing configuration.

Abstract: A journaled database system may comprise data nodes that maintain a collection of data and provide read access to the data to a client in accordance with a read schema and write access to the client in accordance with a write schema. A change to the schemas may be proposed. A materialization schema may be identified based on correlated determinations that both of the read schema and the write schema are satisfiable based on the materialization schema. The proposed changes may be accepted when the read schema and write schema are simultaneously satisfiable.

Abstract: In one or more implementations, groups of users enter a facility within a short time. Automated systems attempt to predict a grouping for various users, but the predicted grouping may not exhibit a confidence level above a certain threshold level. In such cases, a user interface is generated and presented to an associate to confirm the grouping of users. The user interface includes an image gallery and interface elements that allow for the selection of users into a group. The image gallery includes previously stored images of users, such as images obtained during a registration process or during a previous visit to the facility. In addition, the user interface also includes image data obtained from a camera at the facility depicting visitors at various times or locations. Once a grouping has been selected or confirmed by an associate, group data may be generated and stored for the group of users.
