Abstract: Various methods and apparatus for load balancing traffic via dynamic DNS record time-to-live values (“TTLs”) are described. In at least some embodiments, a DNS layer of a DNS load-balanced system receives performance metrics corresponding to a plurality of server instances. If the DNS layer detects a performance metric imbalance for a server instance, it adjusts the TTL value for the DNS records associated with that instance. For example, the DNS layer can lower the TTL value in the DNS records associated with the server instance. This means that clients that have DNS record associated with this server instance will make more frequent DNS queries, thus resulting in at least some of those clients receiving IP addresses for other server instances. In some embodiments, the DNS layer can implement a load balancing scheme that determines which network address(es) to include in a DNS response based on the received performance metrics.

The first and second pairs of support members can be disengaged so that the stack of totes can be realigned relative to the support members so that the next tote at the bottom of the stack can be removed.

Abstract: Aspects of the present disclosure relate to machine learning techniques for identifying collections of items that are visually complementary. These techniques can relying on computer vision and item imagery. For example, a first portion of a machine learning system can be trained to extract aesthetic item qualities from pixel values of images of the items. A second portion of the machine learning system can learn correlations between these extracted aesthetic qualities and the level of visual coordination between items. Thus, the disclosed techniques use computer vision machine learning to programmatically determine whether items visually coordinate with one another based on pixel values of images of those items.

The system includes a video doorbell having a presence sensor and a security hub component communicatively coupled with the video doorbell. The security hub component includes a microphone for capturing sound within the premises, at least one speaker positioned within the premises, an audio driver for driving the speaker, a storage device, and a processor coupled to the microphone, the storage device, and the audio driver. The processor executes machine-readable instructions that control the processor to: capture, using the microphone, audio content of sounds within the premises; store the audio content in the storage device; and control the audio driver to play the audio content through the speaker in response to receiving an indication of the presence of a visitor from the video doorbell.

Abstract: The effect of intent bias on content performance can be determined in order to provide more relevant content in response to a query or other opportunity. Performance data can include the frequency with which an action, such as a purchase, occurs in response to an instance of the content being displayed. An intent bias model can be trained using the performance data for two or more intents, such as an action intent and an explore intent. Once the intent bias for an offer is determined, a normalized performance value can be obtained that does not include the effects of the bias. The normalized values can be used to select and place content based on actual performance.

Abstract: This disclosure describes techniques for resolving discrepancies that occur to interrelated computing resources from computing resource drift. Users may describe computing resources in an infrastructure template. However, computing resource drift occurs when “out-of-band” modifications are made to the computing resources and are not reflected in the infrastructure template. To resolve discrepancies between the infrastructure template and the out-of-band modifications to the computing resources, a notification may be output to a user account associated with the computing resources detailing the differences. An updated infrastructure template may be received that resolves the differences, such as by including configuration settings that reflect a current state of the computing resources. The computing resources may then execute a workflow using the updated template, such that the workflow is executed on all of the computing resources in a current state.

Abstract: A speech interface device is configured to receive response data from a remote speech processing system for responding to user speech. This response data may be enhanced with information such as a remote ASR result(s) and a remote NLU result(s). The response data from the remote speech processing system may include one or more cacheable status indicators associated with the NLU result(s) and/or remote directive data, which indicate whether the remote NLU result(s) and/or the remote directive data are individually cacheable. A caching component of the speech interface device allows for caching at least some of this cacheable remote speech processing information, and using the cached information locally on the speech interface device when responding to user speech in the future. This allows for responding to user speech, even when the speech interface device is unable to communicate with a remote speech processing system over a wide area network.

Abstract: Technologies are provided for managing routing updates within computer networks using brick identifier (ID) values. For example, brick ID values can be assigned to bricks of routers within a network. When a router of the network receives a routing update, the router can check the brick ID value of the routing update and compare it to its assigned brick ID value. If the brick ID values match, then the router can process the routing update using a preferred procedure. If the brick ID values do not match, then the router can process the routing update using a standard procedure. The preferred procedure can result in faster convergence of routing changes within the network.
