Abstract: Provided is a system for facilitating recovery of deleted computing resources in a cloud network environment. A centralized resource recovery service may communicate with a plurality of resource management services that are each configured to create, modify, or delete their respective computing resources such as storage volumes, databases, and compute instances. The resource recovery service may allow creation of immutable resource retention rules that are, under certain conditions, unable to be deleted or modified, even by an administrative user who created such retention rules. Such immutable retention rules may be used to thwart malicious attempts to permanently delete resources by deleting the retention rules that govern such resources. Since such attempts to delete such immutable retention rules would fail, the retention rules would continue to apply and allow deleted resources to be placed in a recoverable state according to the retention rules.

Abstract: An aspect of the present disclosure facilitates routing diverse incoming requests to optimal computing options while satisfying requisite performance metrics. In one embodiment, in a computing environment having multiple compute types, a historical data containing characteristics in transport payloads of incoming requests, and characteristics in processing corresponding incoming requests by respective compute types is collected. A system trains, based on the historical data, a machine learning (ML) model to select compute types for incoming requests. Upon receiving a new incoming request sought to be processed, the system extracts from a transport payload of the new incoming request, the first set of characteristics to create a new request context. The system then applies the ML model to the new request context to identify a target compute type and forwards the new incoming request to the target compute type.

Abstract: Methods and compositions are provided for the improvement of homology-directed repair of a double strand break in a plant cell, via the use of a polynucleotide comprising sequences homologous to the target site. In some aspects, the double strand break is created by an RNA-guided Cas endonuclease. The homology-directed repair of the double-strand break may include incorporation of a heterologous polynucleotide, for example a gene encoding a trait of agronomic importance. The homology-directed repair of the double-strand break may occur as a result of template-directed repair using a polynucleotide repair template.

Abstract: A file is segmented into upper-level segments having references to lowest-level segments. Upper-level segments are aligned at fixed-size boundaries. First shards are formed. Each shard is aligned independent of an alignment of an upper-level segment and includes at least a subset of references from the upper-level segment. First shards are assigned to similarity groups within which deduplication is performed. Incremental changes are received. A virtual synthetic full is generated by segmenting new data into new upper-level segments. New upper-level segments are aligned at fixed-size boundaries and include new references to new segments of the new data. Second shards are formed. The shards include shards that include new references from the new upper-level segments and have new assignments to the similarity groups and other shards. The other shards include copies of at least subsets of references from the first shards and retain assignments to the similarity groups of the first shards.

Abstract: A file is segmented into upper-level segments having references to lowest-level segments. Upper-level segments are aligned at fixed-size boundaries. Shards are formed for each upper-level segment. Each shard includes references from a respective upper-level segment and is assigned to a respective similarity group within which deduplication is performed. A determination is made that a count of shards in a particular set of shards bounded within a particular upper-level segment exceeds a threshold shard count by an excess shard count. A number of shards, equal to the excess shard count, and having the fewest number of references is identified and merged into other immediately adjacent shards to reduce the count of shards to the threshold shard count.

Abstract: Digital content authentication using a cryptographic possession factor is described. In one or more examples, a navigation request to access a webpage is received and verified, over a plurality of iterations over a session, that an originator of the navigation request maintains a cryptographic token as bound within a browser through use of a public key associated with the cryptographic token. A log describing the verifying is stored and then a determination is made that the webpage involves additional authentication usable to extend the session to access the webpage. A level of the authentication is selected for access to the webpage based on the cryptographic token maintained at the browser and the log. Access to the webpage is controlled based on the selected level of authentication.

Abstract: A chiplet-based smart integrated compute system includes a safe compute subsystem and a safe compute and safety monitoring subsystem linked by die-to-die interconnects for high-speed, low-latency, freedom-from-interference operation. Dedicated secondary storage subsystems, clock-generation subsystems (with crystal oscillators), and power-regulation subsystems (with pre-regulators) provide domain-specific memory, timing, and power. A safe smart power management subsystem with a microcontroller manages intelligent distribution, autonomous power-on/reset, over-the-air (OTA) updates to power-management integrated circuits, and selective isolation during faults. The microcontroller monitors thermal/electrical health and can selectively shut down a faulty domain. The safe compute subsystem may serve as a secure communication gateway to external electronic control units via a wireless link on a network, using a cryptographic processing unit with hardware-embedded keys.

Abstract: Techniques discussed herein relate to an object-relational database management system (ODMS) (e.g., a PostgreSQL ODMS) that provides in-line materialization of database pages corresponding to read requests. A replica node of the ODMS may be configured to share access to a shared block storage volume with a primary node. The replica node may receive log updates from the primary indicating changes to the object-relational database. The read replica, in response to receiving a read request, may update a previous version of a database page, store the database page in local memory, and replay the log updates to update the database page in local memory. Data may be provided from the updated database page in response to the read request.

Abstract: Techniques discussed herein relate to an object-relational database management system (ODMS) (e.g., a PostgreSQL ODMS) that utilizes a shared block storage volume (SBSV) for storage. The SBSV may utilize a file system that enables a single-writer-multiple reader model in which a primary computing node may read or write to the SBSV and one or more replica computing nodes are restricted from writing to the SBSV. To enable the primary computing node to write data at its own pace, regardless of the status of synchronization at each of the one or more replica computing nodes, the SBSV may include a staging area that maintains data that has not yet been updated at one or more of the replica computing nodes. When the primary computing node no longer maintains the data in local memory, the one or more replica computing nodes may obtain the data from the staging area of the SBSV.
