The first device determines a defective block of the blockchain and receives a replacement for the defective block from a second device. The first device determines a recalculated blockchain that includes the replacement for the defective block. |

Data enrichment as a service
Systems and methods for data enrichment as a service are described herein. A service provider of a computing resource service provider may provide services for enriching data with additional data. The service provider may receive a set of enrichment parameters. The enrichment parameters may be used to determine whether data obtained by the service provider is eligible for enrichment. If data is eligible for enrichment, the data may be enriched according to the enrichment parameters, thereby generating enriched data. The enriched data may be stored in association with the data. |

Data migration and integration system
A data migration and integration system is disclosed. In various embodiments, the system includes a memory configured to store a mapping from a source schema to a target schema; and a processor coupled to the memory and configured to migrate to a target schema an instance of source data organized according to the source schema, including by using a chase engine to perform an ordered sequence of steps comprising adding a bounded layer of new elements to a current canonical chase state associated with migrating the source data to the target schema; adding coincidences associated with one or more of the target schema data integrity constraints and a mapping from the source schema to the target schema; and merging equal elements based on the coincidences; and repeat the preceding ordered sequence of steps iteratively until an end condition is met. |

Remote code execution
Methods and systems are disclosed for remote code execution between computing environments having various dissimilarities. Client requests at a source environment lead to calls of various types lacking immediate support within the source environment. Calls are delegated to the target environment, where function schemas, data schemas, or copies of source-side schemas are variously used to reconcile called source-side entities with their target-side counterparts. Inconsistencies between name and data representations and datatypes are also addressed. Serially communicated (JSON) parameters are resolved into required target-side multi-level parameter structures, and vice versa. Expedited bulk data access to/from a database layer is supported. A use case is described for phased migration of a software application. Generic and extensible remote code execution allows rapid migration, adaptation, or deployment of software applications across diverse computing environments. |

Automatic creation of database objects
Disclosed herein are various embodiments for a system for the automatic creation of database objects. An embodiment operates by receiving an image of a definition of an unknown type of database object to be created in a database. A first keyword of one or more keywords is identified in a text of the image, wherein the text includes one or more values associated with the first keyword. It is determined that the unknown type of database object corresponds to the first type of database object based on the identified keyword. A database object of the first type of database object is generated for the database based on the one or more values. |

Sustainable energy tracking system utilizing blockchain technology and Merkle tree hashing structure
Apparatus and associated methods relate to generating energy blocks on a blockchain corresponding to generation, transmission, and consumption of predetermined quanta of energy represented by corresponding records in an associated Merkle trie. In an illustrative example, individual energy data records may be hashed. Each hash may be stored in a leaf node of a Merkle trie. The individual energy data records may be aggregated to correspond to represent a predetermined quantum of energy. The individual energy data records may include energy generation records. The energy blocks may be associated with scheduling, delivery, and consumption data for the energy quantum. Various embodiments may advantageously provide secure, verifiable, and immutable tracking and processing of energy generation, transmission, and consumption of physical energy quanta across one or more distributed energy networks. |

File systems with global and local naming
A method for data storage includes specifying a plurality of File Systems (FSs) for use by multiple clients, including assigning to the FSs both respective global identifiers and respective client-specific names. The plurality of FSs is managed using the global identifiers, and files are stored for the clients in the FSs using the client-specific names. |

Efficient usage of one-sided RDMA for linear probing
Systems and methods for reducing latency of probing operations of remotely located linear hash tables are described herein. In an embodiment, a system receives a request to perform a probing operation on a remotely located linear hash table based on a key value. Prior to performing the probing operation, the system dynamically predicts a number of slots for a single read of the linear hash table to minimize total cost for an average probing operation. The system determines a hash value based on the key value and determines a slot of the linear hash table to which the hash value corresponds. After predicting the number of slots, the system issues an RDMA request to perform a read of the predicted number of slots from the linear hash table starting at the slot to which the hash value corresponds. |

Universal serial bus time synchronization
An apparatus includes components, a distributed timebase circuit, an interface and a Time Synchronization Circuit (TSC). The timebase circuit is configured to provide local timebases in physical proximity to the components, and synchronize the local timebases to a global timebase so as to provide a consistent time measurement. The interface is configured to be coupled to one or more devices. Transmissions on the interface are logically divided into a plurality of frames. Time on the interface is defined based on a frame number identifying a particular frame. The TSC is configured to capture a first timestamp based on the frame number corresponding to a point in time on the interface, and to concurrently capture a second timestamp based on a local timebase corresponding to the point in time, wherein the first timestamp and the second timestamp correlate time on the interface to the consistent time measurement. |

Information handling system bus out of band message access control
An information handling system bus port above a subject information handling system bus device may host an information handling system bus out of band message access control list of information handling system bus target device identifiers of other information handling system bus connected devices that the subject device is permitted to communicate with. The port may compare an information handling system bus target device identification field in out of band messages from the subject device to the list and route only out of band messages from the subject device in which the target device identification in the target device identification field is on the access control list through the information handling system bus. The port may discard (and generate error notifications, statuses, etc.) for out of band messages in which the target device identification in the target device identification field is not on the access control list. |
