Techniques for management of virtual representations (e.g., digital twins) of infrastructure are disclosed. For example, a method comprises obtaining at least one virtual representation of an infrastructure, wherein the virtual representation represents the infrastructure in a first state. The method further comprises applying at least one dataset to the virtual representation to artificially advance the virtual representation to represent the infrastructure in a second state. The method further comprises obtaining results representing the infrastructure in the second state, responsive to applying the at least one dataset to the virtual representation, wherein at least a portion of the results are indicative of an issue with the infrastructure, and then initiating one or more debugging actions with respect to the infrastructure to address the issue.

Techniques are provided for securing data storage by slicing swapped data portions into data fragments and shuffling a physical storage location of the data fragments. One method comprises obtaining at least one data item; dividing the at least one data item into a plurality of data portions; swapping respective positions of at least two of the data portions of the at least one data item; slicing the plurality of data portions, following the swapping, into a plurality of data fragments; and shuffling a distribution of the data fragments across a plurality of storage nodes in a storage system by moving at least one data fragment from a current physical storage location on a current storage node to a different physical storage location on a different storage node. A predefined number of the plurality of data fragments may be needed to reconstruct the data item.

A system and method for electronic collaboration including receiving, by a first digitizer of a first host, a mode switch notification, based on the mode switch notification, changing a mode of the first host to a collaborative mode, sending local content, by the first host, displayed on a multipurpose display screen of the first host to one or more collaboration hosts, receiving, by the first host, published content from the collaboration hosts, displaying the published content and the local content concurrently on the multipurpose display screen of the first host, and updating the multipurpose display screen with updated local content and received published content.

Techniques for processing metadata (MD) may include: determining, in accordance with one or more criteria, a plurality of MD blocks that are similar and expected to have matching corresponding portions of MD in at least some of the plurality of MD blocks; forming a MD superblock including the plurality of MD blocks; filtering the MD superblock and generating a filtered MD superblock, wherein said filtering includes rearranging content of the MD superblock so that a first plurality of MD portions that are similar are grouped together in the filtered MD superblock, wherein at least some of the first plurality of MD portions that are similar are expected to match; and compressing the filtered MD superblock and generating a compressed filtered MD superblock. Filtering may include performing a bitshuffle algorithm that includes performing a bitwise transpose of a matrix of the MD blocks in the MD superblock.

Metadata compression techniques

A parallel decompression engine has separate hardware paths for sequence processing and repeated byte copying/placement. Literal byte extraction logic obtains literal bytes from a selected sequence. Literal byte write logic writes the obtained literal bytes into an uncompressed data set that is being generated. Offset and length extraction logic obtains the offset and length of repeated bytes from the selected sequence. In a separate hardware path, copying and placement logic uses the offset and length to find and copy the length of repeated bytes at the specified offset in the uncompressed data set, and place the copied repeated bytes back into the uncompressed data set adjacent to the literal bytes.
