The method can terminate with providing results of the execution to the customer.

Abstract: Systems and techniques are provided for presence and directional motion detection. Signals may be received from a sensor positioned in a structure. An indication of directional motion may be generated based on the signals from the sensor. The indication of directional motion may be generated without using signals from additional sensors. A control signal for a device in the structure may be generated in response to the indication of directional motion. The control signal may be sent to the device in the structure to be implemented by the device.

Abstract: Techniques for providing an on-demand development environment are described. A service of a provider network receives a request to launch a development environment, such as a notebook, from an electronic device. The service obtains an identification of a computing cluster hosted by the provider network. The service obtains an identification of a compute instance hosted within the provider network, the compute instance executing a software environment to host one or more development environments. The service causes the compute instance to launch a development environment. The service sends a message to configure the launched development environment to execute a computer program written in the development environment using the computing cluster. The service generates a token to secure communications between the electronic device and the development environment and sends the token to an originator of the request.

The method also includes monitoring ongoing events of the payment gateway system associated with ongoing transaction messages communicated from point-of-sale (POS) devices to the payment gateway system and detecting the event in the ongoing events. The method further includes, in response to detection of the event, generating a HTTP POST message including event data of the event, and communicating the HTTP POST message to the application URL to cause the merchant control interface to display the event data in a chart for visual representation of the event data.

Abstract: Several API specification files that each include references to code elements that are defined within separate definitions and resources files may be merged together into a single specification for the new API. In this way, specifications for shared code elements that are common across the several specification files may be created without rewriting these specifications each time they are used in an API. A specification merging tool may look for a common reference in the API, match that reference to a definition or resource from the respective definition or resource document, and add that definition or resource to a merged specification file.

Abstract: A multi-leg transport system receives a transport request and determines a number of transfer locations between the origin location and the destination. The system selects a first provider to transport the user from the origin location to a transfer location and remotely monitors the position of the user as the user travels to the transfer location. In response to determining that the travel time to the transfer location is within a threshold, the system selects a second provider to transport the user from the transfer location to either the next transfer location or the destination for the transport request.

Abstract: In various implementations, methods and systems resource balancing in a distributed computing environment are provided. A client defined resource metric is received that represents a resource of nodes of the cloud computing platform. A placement plan for job instances of service applications is generated. The placement plan includes one or more movements that are executable to achieve a target placement of the job instances on the nodes. It is determined that the placement plan complies with placement rules. Each placement rule dictates whether a given job instance of the job instances is suitable for placement on a given node of the nodes. The placement plan is executed based on determining that the target placement of the job instances improves balance of resources across the nodes of the cloud computing platform based on the resource represented by the client defined resource metric.
