Abstract: Methods, systems, and devices for background change log loading for power loss within a memory system are described. Techniques described herein may enable a memory system to insert a flag having a value that indicates whether a logical block address has been inserted into a foreground change log as part of a garbage collection operation. In response to performing a merge operation to flush a logical-to-physical (L2P) mapping from a volatile memory to a non-volatile memory, the memory system may determine, in accordance with the value of the flag, whether to store one or more entries of the background change log to the non-volatile memory, or whether to invalidate the one or more entries in the L2P mapping. If the memory system loses power unexpectedly, the memory system may rebuild the background change log upon power on using the pointers.

Abstract: A domain abuse detection system periodically retrieves trending topics, topic attributes, and interest metrics data from data sources. The domain abuse detection system also prompts a language model to generate a list of tokens for each trending topic based on the topic attributes, as well as retrieved web content related to the topic. The domain abuse detection system then analyzes the trending topics to identify “hot” and “rising” topics based on the interest metrics data. The domain abuse detection system prompts a language model to identify which of the hot and rising topics are exploitable for domain abuse. For each exploitable topic, the domain abuse detection system searches domain related databases (e.g., domain registration databases) for domain entities based on the tokens. ring) and generate a domain abuse report.

Abstract: In an example, a memory controller is configured to: check whether a logical block address corresponding to a host read command is maintained in a write buffer; determine a level of an amount of drift corresponding to the logical block address if the logical block address is not maintained in the write buffer, where different levels of the amount of drift correspond to different read voltages; and send a read command to a non-volatile memory device according to the level of the amount of drift corresponding to the logical block address. At least two of the processes of checking whether the logical block address is maintained, determining the level of the amount of drift, or sending the read command are performed in parallel.

The memory system may replace invalid blocks from superblocks having a relatively small quantity of invalid blocks with blocks (e.g., blocks from a same plane) from superblocks having a relatively large quantity of invalid blocks, which may result in the generation of complete and incomplete superblocks.

Abstract: Methods, systems, and devices for validity mapping techniques are described. A memory device may use a change log to update a mapping that indicates whether data stored at respective physical addresses is valid. For example, the memory device may receive a command associated with data having a corresponding set of addresses (whether logical block addresses or physical addresses). The memory device may set an entry of the change log based on whether the set of addresses are consecutive. For example, the memory device may identify whether the set of addresses are consecutive and may set a flag in the entry of the change log to indicate whether the addresses are consecutive. Then, the memory device may update one or more entries of the mapping corresponding to the entry of the change log to indicate whether the addresses corresponding to the one or more entries of the mapping store valid data.

Abstract: A power head of a directional drill includes a main motor, gearbox, main shaft, active drill pipe, and water swivel. The gearbox has a driving shaft connected to the main motor and engaged with the main shaft via a gear. One end of the main shaft is fixedly connected to the active drill pipe, while the other end of the driving shaft links to an angle adjuster through the gearbox, enabling efficient toolface adjustment and braking of the main motor. The water swivel mandrel connects to the active drill pipe via a connecting shaft with an axial floating structure. A connecting sleeve near the water swivel forms a hexagonal sleeve sliding pair with the connecting shaft, preventing axial impacts on mandrel support bearings during drilling. This design enhances the service life of the bearings and reduces equipment repairs, improving the reliability and efficiency of the drilling process.
