US10579364B2	Upgrading bundled applications in a distributed computing system A new snapshot of a storage volume is created by instructing computing nodes to suppress write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot and finalizes and performs garbage collection with respect to segments allocated to the previous snapshot. Subsequent write requests to the storage volume are then performed on the segments allocated to the new snapshot. An orchestration layer implements a multi-role application that is provisioned with virtualized storage and computation resources. A snapshot of the application may be created and used to rollback or clone the application. Clones snapshots of storage volumes may be gradually populated with data from prior snapshots to reduce loading on a primary snapshot. Upgrades for bundled applications may be defined and executed for containers and roles of the bundled application.

The controller sorts the data groups based on a predetermined sorting mechanism to generate a first sorting hash data. The controller includes an efuse region for writing the predetermined sorting mechanism. When the controller determines that a second sorting hash data of a second firmware data is identical to the first sorting hash data or a second hash data of the second firmware data is identical to the first hash data, the second firmware data is allowed to update the controller.
US10579347B2	Self re-encoding interpreted application A method for self re-encoding an interpreted application includes parsing a string of characters in a comment section of the interpreted application file. Responsive to determining that at least one character of the string of characters is not readable by the target platform, the processor re-encodes the interpreted application file using the string of characters in the comment section. The re-encoding includes parsing a first character in the string of characters. The processor then, optionally, outputs a warning message indicative that a non-native encoding exists in the interpreted application file. The processor parses a second character sequential to the first character. The second character is a first element in a second string of characters indicative of a re-encoding scheme for re-encoding the interpreted application. The processor then outputs a re-encoded application file that is executable by the processor of the target platform.

The concentric ring buffer has a fixed total memory size based on the number of ring buffers and segments. Each segment of each ring buffer is populated in a first-in-first-out manner with a value calculated for the data characteristic for a particular length of base unit and with a particular precision. When a ring buffer is full and another value is calculated, the oldest value is transferred to a next ring buffer or deleted if there is none.

Thus, the NAND doesn't perform the second and third phases of the erase process. This is much faster and results in data that cannot be reconstructed. In some examples, because the erase pulse is not actually applied and because this is simply a programming operation, data may be rendered unreadable at a per-page level rather than a per-block level as in traditional erases.

If local storage resources are critically low, lossy assets are purged. A user's interactions with his/her digital assets are monitored, and assets that are perceived to be less important to a user are purged from local storage before assets that are perceived to be more important. An asset may be deemed to be “important” based on any number of relevant criteria, such as user selection, user rating, or user interaction.
