Abstract: A system comprising one or more computing devices implements a vehicle information extraction service. The vehicle information extraction service enables customers to provide access to proprietary encoding protocols used by the customers to communicate over a bus of a vehicle, wherein the proprietary protocols are used by the vehicle information extraction service to perform vehicle information monitoring, while at the same time protecting the confidentiality of the proprietary protocols from being accessed by third parties. Also, the vehicle information extraction service enables streaming of relevant vehicle information corresponding to customer defined event criteria without requiring non-relevant vehicle information to be streamed, which would consume considerable network resources.

Abstract: Techniques are described for providing managed computer networks, such as for managed virtual computer networks overlaid on one or more other underlying computer networks. In some situations, the techniques include facilitating replication of a primary computing node that is actively participating in a managed computer network, such as by maintaining one or more other computing nodes in the managed computer network as replicas, and using such replica computing nodes in various manners. For example, a particular managed virtual computer network may span multiple broadcast domains of an underlying computer network, and a particular primary computing node and a corresponding remote replica computing node of the managed virtual computer network may be implemented in distinct broadcast domains of the underlying computer network, with the replica computing node being used to transparently replace the primary computing node in the virtual computer network if the primary computing node becomes unavailable.

Abstract: Connectivity between a radio-based application pipeline processing server and a control plane of a provider network is verified. Based on requests received at the control plane, a first isolated request handler, a second isolated request handler and an offloading manager are launched at the server. The offloading manager causes a first network function for which a request is received from the first request handler to be executed at a first network function accelerator of the server, and a second network function for which a request is received from the second request handler to be executed at a second network function accelerator of the server.

Abstract: A cloud-based software testing service orchestrates the testing of pieces of software, such as software to be deployed to a vehicle. Also, the cloud-based software testing service, in response to detecting a failure, automatically instantiates multiple virtual machines configured to emulate a testing environment for testing one or more of the pieces of software, with which the detected failure is associated. These virtual machines allow for rapid execution of multiple instances of re-testing to be performed to determine a reproducibility measure for the failure. Based on the reproducibility measure, additional re-testing may be performed. Expanded testing logs generated during the re-testing are provided to a trained machine learning model that automatically determines, for reproducible failures, a root cause of the failure.

Abstract: Contents of client-initiated handshake messages of a security protocol are obtained at a handshake processing offloader configured for an application. The offloader uses a first security artifact (which is inaccessible from a front-end request processor of the application) and the contents of the handshake messages to generate a second security artifact. The second security artifact is transmitted to the front-end request processor, which uses it to perform cryptographic operations for client-server interactions of the application.

Abstract: Techniques for performing readout and reset of fluxonium qubits are disclosed. When fluxonium hardware components are coupled to a quantum metamaterial through a readout resonator, said components may be dispersively coupled such that a quantum state of the corresponding fluxonium qubit is read out through the quantum metamaterial, and then the state of the fluxonium qubit is subsequently reset in order to proceed with a quantum computation to be performed. Alternatively, when fluxonium hardware components are coupled directly to a quantum metamaterial, a quantum state of a fluxonium qubit is read out using resonance fluorescence, and then may be subsequently reset back to its ground state, also using resonance fluorescence. A width of a passband of the quantum metamaterial, along with frequencies of the control sequences used, may be tuned such that either readout or reset is selectively activated.

Abstract: A storage object and an associated permissions record is stored at a storage server. The permissions record indicates that some storage consumers are not permitted to perform a type of I/O operation on the storage object. In response to detecting that an event of a deletion triggering type with respect to the records, a modified version of the permissions record is stored at the server, indicating that the storage consumers remain prohibited from performing the I/O operations. In response to receiving a command to perform a particular I/O at the server after the modified version has been stored, the modified version is used to process the command.

Abstract: A service may generate keywords to produce synthetic documents, while maintaining data privacy for the original documents. A client may extract keyword sequences from locally stored documents, embed the keyword sequences into vectors, and generate a DP-KDE distribution based on the vectors. The DP-KDE distribution preserves data privacy for the original documents. The service receives the DP-KDE distribution, obtains a particular vector from the DP-KDE (e.g., based on a calculated score for the DP-KDE using random Gaussian completions), decodes the particular vector into a sequence of synthetic keywords, and uses the sequence of synthetic keywords to prompt an LLM to produce one or more synthetic documents.

Abstract: A particular hyper-parameter combination (HPC) that was recommended for a first task is included in a collection of candidate HPCs evaluated for a second task. Hyper-parameter analysis iterations are conducted for the second task using the collection. In one of the iterations, the second task is executed using a first iteration-specific set of HPCs, including the particular HPC and one or more other members of the collection. One or more of the HPCs of the first iteration-specific set of HPCs are pruned to generate a second iteration-specific set of HPCs for a subsequent iteration. HPCs are selected for pruning based on a comparison of their results with the results obtained from the particular HPC that was recommended for the first task. A recommended HPC for the second task is identified based on results of the analysis iterations.

Abstract: Respective delegation records indicating that a first access controller and a second access controller have been authorized to grant access to a respective set of cells of a table of a storage management service are stored. In response to receiving an access request of a data accessor, permission records indicating that the access controllers have granted permissions to the data accessor to respective subsets of the table's cells are identified. A collection of cells of the table to which the data accessor has been granted access permission is identified using the permission records, and a response to the access request is generated using the collection.

Abstract: A determination is made that a graphical representation of network health state information pertaining to a client account of a provider network is to be provided. Using respective network metrics groups corresponding to several data sources, a network health state descriptor corresponding to a resource associated with the client account is generated. A data set usable to generate a graphical display of network health state information of the resource of the client account is transmitted.

Abstract: To reduce power consumption, data bits or a portion of a data register that is not expected to toggle frequently can be grouped together, and be clock-gated independently from the rest of the data register. The grouping of the data bits can be determined based on the data types of the workload being operated on. For a data register configured to store a numeric value that supports multiple data types, the portion of the data register being clock-gated may store a group of data bits that are unused for one or more data types of the multiple data types supported by the data register. The portion of the data register being clock-gated can also be a group of data bits that remain unchanged or have a constant value for numeric values within a certain numeric range that is frequently operated on.

Abstract: Embodiments for a standardized machine data interface protocol are described herein. A request for information about a state of a component of a machine may be received where the request is in an agnostic data format. A particular machine and a particular component of the particular machine may be determined based on the agnostic data format. A data structure of the agnostic data format for the particular machine and the particular component may be determined where the data structure is associated with the state. The state may be requested from the particular machine for the particular component using a format of the data structure. The state of the particular component may be received according to the format of the data structure. The state of the particular component may be converted from the format of the data structure to the agnostic data format of the request.

Abstract: Dynamic camera image presentation in a vehicle is described herein. In an example, a computer system presents, on a display of a vehicle, first image data generated by a camera of the vehicle. The first image data is based at least in part on a first presentation property. The computer system determines a trigger to change the first presentation property and a second presentation property associated with a type of the trigger. The computer system presents, on the display, second image data generated by the camera. The second image data is presented based at least in part on the second presentation property.

Abstract: Techniques are described for detecting a periphery of a surface based on a point set representing the surface. The surface may correspond to a display medium upon which content is projected. A shape model may be matched and aligned to a contour of the point set. A periphery or edge of the surface and corresponding display medium may be determined based on the aligned shape model.

Images captured by the camera modules of the camera system may be utilized for any purpose.

Abstract: Conflicts may be detected between a generated access management policy and invoked identity and access management policies. An access management policy to be updated to provide expected results for example requests may be received. Another access management policy that would be invoked to evaluate the example access requests may be identified. A conflict between the expected results for the updates and the invoked access management policy may be determined. An indication of the conflict between the expected results of the example requests may be provided.

Abstract: An application debugger may define multiple unique initial states of execution for an application on behalf of a client. These unique initial states may include unique sets of application variable values. The application debugger may then create respective application runtimes initialized with the respective sets of application variable values. Then, the execution runtimes may be independently executed to a termination condition that may include a defined set of breakpoints, a normal termination or an abnormal termination. The application debugger may then receive termination state information from the respective execution runtimes, provide additional analysis of these termination states and report results to the client.
