Abstract: A non-relational database may be emulated using a relational database with a distributed data store. A request to access the non-relational database may be received at a frontend for a relational database engine that emulates an interface for a non-relational database engine. The request may be translated into the format for the relational database engine and performed by the relational database engine. The relational database engine may access data for the non-relational database at storage nodes that store the data in a relational table column of non-relational data type.

Abstract: Online block parsing techniques are performed that use anchor tokens. When a log entry of a log stream is received, the log entry may be tokenized into an ordered series of log units. The log units may be matched with anchor tokens in previously initialized log templates to determine a matching log template. A log template based on the matching log template may be provided with the tokenized log entry to a destination for a parsed version of the log stream.

Abstract: Systems, methods, and collection devices are disclosed for rapid, local PCR testing. The PCR testing system may be configured for use with a disposable sample collection device that includes a swab configured for collecting a biological sample from a patient; and a sample container configured to receive the swab and separate a bulk quantity of the biological sample from the swab for containment in a bulk collection chamber, which is located with the sample container, wherein the sample container is configured to meter a selected volume of the biological sample into a PCR sample tube, which contains a lyophilized master mix, releasably attachable to the sample container.

Abstract: Techniques are described for enabling users of a certificate management service to create certificate issuance policies that can be applied to certificate issuance requests across both public and private certificate authorities (CAs) and other certificate-related services. According to embodiments described herein, a certificate issuance policy includes one or more certificate issuance rules to be applied to requests associated with one or more specified user accounts or roles for certificate-related resources (e.g., public certificates, private certificates, etc.). The application of a certificate issuance rule can be conditioned on a particular request context (e.g., based on a user account or role associated with a request, a type of certificate requested, a subject name identified in the request, etc.) and can specify a wide range of actions to be performed on requests matching a rule (e.g., allowing or denying a request, modifying one or more parameters of the request, etc.).

Abstract: Techniques for generating and utilizing investigative playbooks for cloud security events are described. Activity is detected indicative of a potential compromise in association with a resource of a multi-tenant cloud provider network. API calls originated by a client are determined to utilize API methods that exist within a set of known API methods included in a formal model of attack tactics. Responsive to both the detection and the determination, an investigative playbook is executed, based on the activity, that includes multiple logical tests to generate an attack report that can be presented to a user such as a security analyst for use in investigating cloud security events.

Abstract: Techniques for generating customized synthetic voices personalized to a user, based on user-provided feedback, are described. A system may determine embedding data representing a user-provided description of a desired synthetic voice and profile data associated with the user, and generate synthetic voice embedding data using synthetic voice embedding data corresponding a profile associated with a user determined to be similar to the current user. Based on user-provided feedback with respect to a customized synthetic voice, generated using synthetic voice characteristics corresponding to the synthetic voice embedding data and presented to the user, and the synthetic voice embedding data, the system may generate new synthetic voice embedding data, corresponding to a new customized synthetic voice. The system may be configured to assign the customized synthetic voice to the user, such that a subsequent user may not be presented with the same customized synthetic voice.

Abstract: A data storage system stores a plurality of partitions for a volume and at least one parity partition for the volume. The parity partition includes erasure encoded data that enables any one of the partitions to be reconstructed using the erasure encoded data of the parity partition. Additionally, the data storage system is configured to generate parity data updates in response to modifications to the volume and store updated parity data in the parity partition, such that a current state of any of the partitions of the volume can be re-created in response to a loss of one of the partitions.

Abstract: Aspects related to a resource-constrained system are described herein that can provide object storage services after a service interruption is resolved, even if all of the transactions that were pending and incomplete prior to the service interruption have not yet been recovered and/or executed. For example, file systems implemented by computing systems of the resource-constrained system may treat each file or directory as a separate object. Thus, a transaction directed to one file may not affect the file's directory or other files in the directory. As a result, the resource-constrained system can achieve read-after-write consistency without first recovering and executing the pending, incomplete transactions. Instead, read-after-write consistency for an object can be achieved simply by completing any pending, incomplete transaction directed to that object. Accordingly, the resource-constrained system can provide object storage services to user devices immediately after the service interruption is resolved, thereby resulting in fast crash recovery times.

Abstract: Vulnerabilities to physical memory, such as server dynamic random access memory (DRAM) with error correction code (ECC) capability, can be mitigated though the use of guard pages allocated in that physical memory. Physical memory pages can be mapped to virtual memory pages of a contiguous virtual address space. When an error such as a bit flip is detected in a physical memory page, the data from that physical memory page can be copied to a protected page, such as a guard page or page isolated from other sensitive data. Information such as an error correction code (ECC) can be used to determine and correct the erroneous bit. The mappings in a related page table can be updated such that the same virtual pages or addresses are then mapped to the guard page that now includes the relevant data.

Abstract: This disclosure describes, in part, a mobile apparatus for identifying items within a facility using an omnidirectional imaging system. For instance, the mobile apparatus may include a main frame, a chassis attached to the main frame, a basket that attaches to the chassis in order to prevent the basket from contacting the main frame, and an omnidirectional imaging system providing image data in and around the mobile apparatus. A user may place item(s) within a receptacle of the basket. The mobile apparatus may further include a handlebar module attached to the main frame, the handlebar module including the omnidirectional imaging system and a computing system for identifying items and events in and around the cart.
