    Abstract: A device management service may enforce compliance of remote devices with device specifications by disabling or enabling use of client certificates by applications installed on the devices. The device management service receives configuration data from an agent installed on the remote device. If the device management service determines that the device is no longer compliant with specifications for the device, then the device management service may prevent subsequent use of client certificate(s) by applications on the device to establish certificate-based connections. For example, the device management service may disable or revoke a client certificate or may instruct the device to disable or remove the client certificate. If the device becomes compliant at a subsequent time, then the device management service may enable the client certificate or cause a new client certificate to be sent to the device.

    Abstract: Technologies are disclosed for interacting with a virtual assistant to request updates associated with one or more events and/or perform actions. According to some examples, a user may use their voice to interact with a virtual assistant to receive updates relating to events occurring during a certain period of time. For example, a user may request an update associated with one or more events occurring that day. The system may access data sources (e.g., calendar services, email services, etc.) to obtain data associated with the events, tag the events according to one or more conditions indicated by the data, and/or rank the events according to the tags. In addition, to resolve conditions associated with the events, the virtual assistant may also include options in the update to perform certain actions and/or to provide response data. The virtual assistant may generate the update and audibly provide the update to the user.

    Abstract: Methods and apparatus for partitioned private interconnects to provider networks are described. At least a portion of available bandwidth of a private physical interconnect between a provider network and a connectivity intermediary's network is designated as the bandwidth limit of an interconnect partition set up on behalf of a customer at the request of the intermediary. The intermediary's network comprises one or more devices to which at least one of the customer's devices is connected. Access to one or more resources of the provider network via the interconnect is enabled. Traffic monitoring results associated with the interconnect are used to enforce the designated bandwidth limit of the partition.

    Abstract: Techniques for updating a chatbot definition are described. In some examples, this updating includes receiving an edit to intent characteristics for a stage of a plurality of stages in a chatbot flow, identifying a stage to modify based on at least the received edit, identifying, for the stage, a default update rule based on the chatbot definition, and updating the stage in the chatbot definition by inferring a next step according to one or more rules for the stage including the identified default update rule.

    Abstract: Techniques for presenting content by a voice-controlled device are described. In an example, the voice-controlled device is operatively coupled to a presentation device and supports dual mode functionalities. In a first mode, the voice-controlled device sends content for presentation at the presentation device. In a second mode, the voice-controlled device presents the content at a presentation interface of the voice-controlled device. Based on speech input from a user indicating an issue with a content presentation in the first mode, the voice-controlled device switches to the second mode and presents a message at the presentation interface indicating that subsequent content presentations would be presented at this interface. The voice-controlled device remains in the second mode until receiving additional speech input necessitating a switch to the first mode.

    Abstract: At a machine learning service, a determination is made that an analysis to detect whether at least a portion of contents of one or more observation records of a first data set are duplicated in a second set of observation records is to be performed. A duplication metric is obtained, indicative of a non-zero probability that one or more observation records of the second set are duplicates of respective observation records of the first set. In response to determining that the duplication metric meets a threshold criterion, one or more responsive actions are initiated, such as the transmission of a notification to a client of the service.
