Abstract: Developers receive automatically designated property change events which caused invalidation of a rendered frame. Some embodiments control display invalidation in part by identifying higher-level frame bounding events in an execution trace, and applying at least one display invalidation constituency filter to lower-level thread events within a frame creation period, thereby obtaining a display invalidation constituency sequence of one or more display invalidation events. The sequence may include a layout property change event and/or a render property change event which invalidated the frame. An initial part of the sequence is designated as a display frame creation cause. Displayed frame invalidation is controlled by altering the display invalidation constituency, e.g., by manual or automated layout/render property change event elimination or event sequence location change, by a reduction in computational resource usage (e.g.

Abstract: Various aspects for data deduplication in a storage system are provided. For instance, a storage controller may perform operations including receiving a data chunk including a set of data blocks, determining a signature for the data chunk, and comparing the signature and a set of reference signatures to determine a match. Responsive to a match, the operations may further include identifying a reference data chunk including a set of comparison blocks associated with the matched reference signature, performing a deduplication technique on the set of data blocks based on the set of comparison blocks, and identifying a subsequent reference data chunk for an estimated next data chunk based on identification of the reference data chunk and prior to receipt of the next data chunk.

Abstract: Embodiments offer database security utilizing dictionary encoding, with certain functionality being implemented inside a secure environment, e.g., a Trusted Execution Environment (TEE). In particular, the secure environment receives a secret key from a data owner, and receives an encrypted query range and a dictionary reference from a query engine. Based upon the query range decrypted using the secret key, and also the dictionary loaded from a database, the secure environment searches the dictionary to produce list of value identifiers corresponding to the query range. The value identifiers are communicated outside the secure environment to the query engine for further processing (e.g., to generate RecordIDs), ultimately producing a query result for a user. Particular embodiments may leverage the processing power of an in-memory database engine in order to perform the role of the query engine that interacts with the secure environment.

The second cross-coupled level shifter includes a first PMOS transistor coupled in series with a first NMOS transistor and a second PMOS transistor coupled in series with a second NMOS transistor. When an input supply voltage is less than a VCCI trigger associated with the output supply voltage, only the first and second NMOS transistors are coupled to contribute to the output control signal and when the input supply voltage is equal to or greater than the VCCI trigger, only the first and second PMOS transistors are coupled to contribute to the output control signal.

For instance, a method may include storing, in a buffer memory, a plurality of comparison blocks, initiating a data deduplication process utilizing the plurality of comparison blocks, and performing garbage collection in conjunction with the data deduplication process. Garbage collection may include maintaining a hit count for comparison blocks of a passive set of comparison blocks in the buffer memory and deleting the passive set from the buffer memory when the hit count is decremented to a predetermined value. The hit count may be incremented and decremented based on utilization of a comparison block in the data deduplication process.

Abstract: A sequence of contiguous pages in an erase block in a non-volatile memory device is programmed and erased. Next, all of the pages in the erase block are programmed with data. Then, the data is read back and verified to determine whether there is an error in the data. When there is an error in the data, then the last page in the sequence is identified as being unstable. If there is no error in the data, then the last page in that sequence is identified as being stable. Thus, the recorded information identifies a point of instability in the erase block. Instabilities can be stabilized by performing additional writes to fill the partially filled word line.
