Abstract: Systems, methods, and computer program products for automating the management of a tiered storage system, which improves the service life and costs of the flash-based storage devices that comprise the storage system. The systems, methods and program products utilize time series learning models to predict the write frequency of each data block for the next cycle of time. Using the write frequency predictions, management of the tiered flash-based storage system can automatically organize and migrate stored data based on storage costs, migration costs and frequency in which the data is accessed. Data that is more frequently accessed and updated is migrated to high-end flash-based storage devices, which are able to endure a greater number of program/erase cycles, while less frequently accessed data is migrated to less expensive, low-end flash-based storage devices, that have a lower maximum number program/erase cycles.

Abstract: The source code of a software artifact may be scanned, and a call tree model with leaf nodes may be generated based on the scan. A set of test cases can be executed against the software artifact and log data from the execution can be collected. A set of untested leaf nodes can be detected and a new set of test cases can be generated to test the untested nodes. The new set of test cases are executed and a subset of the test cases which cover the previously untested nodes are added to the existing set of test cases.

Abstract: A supporting frame includes at least one supporting element, a base and a light-permeable pillar. The supporting element has a first through-hole. A cam is disposed in the supporting element and has a second through-hole and a turning portion. The second through-hole is disposed corresponding to the first through-hole. The base extends to form a sleeve. The light-permeable pillar passes through the first through-hole and the second through-hole and is inserted into the sleeve. The supporting element is capable of sliding along the light-permeable pillar. The turning portion is configured for pushing against an inner wall of the supporting element for fixing the supporting element on the light-permeable pillar.
