A method includes determining a storage modification process for a set of encoded data slices based on a change to the storage parameters associated with storage of data objects in a storage network, where a data segment of the data objects is dispersed storage error encoded into the set of encoded data slices in accordance with dispersed storage error encoding parameters, and where the set of encoded data slices is stored in the storage network. The method also includes executing the storage modification process such that the set of encoded data slices are stored in the storage network in accordance with the changed storage parameters.

The plurality of storage nodes has a non-volatile solid-state storage for user data storage. The plurality of storage nodes is configured to distribute the user data and metadata associated with the user data throughout the plurality of storage nodes, with erasure coding of the user data. The plurality of storage nodes is configured to recover from failure of two of the plurality of storage nodes by applying the erasure coding to the user data from a remainder of the plurality of storage nodes. The plurality of storage nodes is configured to detect an error and engage in an error recovery via one of a processor of one of the plurality of storage nodes, a processor of the non-volatile solid state storage, or the flash memory.

Disclosed embodiments relate to performing updates to Electronic Control Unit (ECU) software while an ECU of a vehicle is operating. Operations may include receiving, at the vehicle while the ECU of the vehicle is operating, a software update file for the ECU software; writing, while the ECU is operating, the software update file into a first memory location in a memory of the ECU while simultaneously executing a code segment of existing code in a second memory location in the memory of the ECU; and updating a plurality of memory addresses associated with the memory of the ECU based on the software update file and without interrupting the execution of the code segment currently being executed in the second memory location in the memory of the ECU.

An integrated circuit has a transceiver circuit and a memory circuit. The transceiver circuit includes stage circuits that each perform at least one function specified by a data transmission protocol. The transceiver circuit is coupled to receive packets of timing test patterns. Each of the stage circuits in the transceiver circuit generates a timestamp in response to receiving each of the packets of timing test patterns. Each of the stage circuits in the transceiver circuit generates a trigger indicating receipt of a predefined reference point in each of the packets of timing test patterns. The memory circuit stores each of the timestamps generated by the stage circuits in response to a respective one of the triggers and outputs the timestamps for analysis.

Replica unavailability in a distributed file system can be managed. For example, a processing device can detect that a replica of data in a volume of a distributed file system is unavailable. In response to detecting that the replica is unavailable, the processing device can create a copy of the data in a memory location that is within the distributed file system and external to the volume. The processing device can then execute a write request by modifying both the data in the volume and the copy in the memory location (e.g., to ensure consistency between the two).

Systems and methods that make use of cluster-level redundancy within a distributed storage management system to address various node-level error scenarios are provided. According to one embodiment, a KV store of a node of a cluster of a distributed storage management system manages storage of data blocks as values and corresponding block IDs as keys. Data integrity errors are reported to the first node in the form of a list of missing block IDs that are in use but missing from the KV store. A metadata resynchronization process may then be caused to be performed, including for each block ID in the list of missing block IDs: (i) reading a data block corresponding to the block ID from another node of the cluster that maintains redundant information relating to the block ID; and (ii) restoring the block ID within the KV store by writing the data block to the node.

A server may receive remaining amount information related to a remaining amount of color material in a first color material cartridge from a printer on which the first color material cartridge is mounted, and send specific information to an external device in a case where the remaining amount of the color material in the first color material cartridge indicated by the remaining amount information is equal to or less than a first remaining amount threshold. The specific information is for changing a state of the printer from a state in which the printing process by using a second color material cartridge to be mounted is restricted to a state in which the printing process by using the second color material cartridge is permitted.

Systems, methods, and circuitries are provided for checking integrity of code received from an external memory. In one example, a system includes a non-volatile memory and a controller. The non-volatile memory includes a first partition configured to store first data corresponding to program code and a second partition configured to store second data corresponding to a copy of the first data. The controller that includes a processor and comparator circuitry. The comparator circuitry is configured to receive a portion of the first data and a corresponding portion of the second data, compare the portion of the first data to the portion of the second data, when the portion of the first data matches the portion of the second data, provide the portion of the first data to the processor, and when the portion of the first data does not match the portion of the second data, generate an alarm signal.

A system that may include multiple driving related systems that are configured to perform driving related operations; a selection module; multiple fault collection and management units that are configured to monitor statuses of the multiple driving related systems and to report, to the selection module, at least one out of (a) an occurrence of at least one critical fault, (b) an absence of at least one critical fault, (c) an occurrence of at least one non-critical fault, and (d) an absence of at least one non-critical fault; and wherein the selection module is configured to respond to the report by performing at least one out of: (i) reset at least one entity out of the multiple fault collection and management units and the multiple driving related systems; and (ii) select data outputted from a driving related systems.

A workgroup-computing-entity-based fail-safe/evolvable hardware core structure is disclosed which includes a 3-hierarchical-level 6-workgroup-Basic-Building-Block (6-wBBB) created to supplant the node-computing-entity-based non-fail-safe/limited evolvable von-Neumann core structure of 3-hierarchical-level 3-node-BBB, (i.e., base-level JO-devices/mid-level main memory/top-level CPU) and all the first-time fail-safe workgroup systems can be subsequently generated in the second period along the workgroup-computing evolutionary timeline. Furthermore, based on the first 6-wBBB evolvable architecture, the workgroup evolutionary processes can go up to 7 generations in creating all the necessary workgroup-computing entity-based hardware core structures, so that all the real-time intelligent workgroup-computing systems can be generated in the third period along the workgroup-computing evolutionary timeline.
