Abstract: Attempts to update confirmation information or firmware for a hardware device can be monitored using a secure counter that is configured to monotonically adjust a current value of the secure counter for each update or update attempt. The value of the counter can be determined every time the validity of the firmware is confirmed, and this value can be stored to a secure location. At subsequent times, such as during a boot process, the actual value of the counter can be determined and compared with the expected value. If the values do not match, such that the firmware may be in an unexpected state, an action can be taken, such as to prevent access to, or isolate, the hardware until such time as the firmware can be validated or updated to an expected state.

Abstract: A computer system for determining whether or not a tool for deploying a software patch should be invoked is provided. The system may include a receiver that receives information regarding patch deployment over a first pre-determined amount of time. The system may include a processor configured to determine, based on the historical information, a patch deployment index. The patch deployment index may characterize patch deployment as a number of patches deployed per unit time. The receiver may receive historical information regarding patch deployment over a second amount of time. The processor may use the historical information regarding patch deployment of the second pre-determined amount of time to determine a second patch deployment index. The processor may compare the first deployment to the second patch deployment index. When the difference between the second index and the first index is greater than a pre-determined threshold, the processor may invoke the tool.

Abstract: Technology for operating a cache sizing system is disclosed. In various embodiments, the technology monitors input/output (IO) accesses to a storage system within a monitor period; tracks an access map for storage addresses within the storage system during the monitor period; and counts a particular access condition of the IO accesses based on the access map during the monitor period. When sizing a cache of the storage system that enables the storage system to provide a specified level of service, the counting is for computing a working set size (WSS) estimate of the storage system.

Abstract: A common action flow for an application is identified by processing session data maintained for a plurality of users to identify a plurality of action flows. Each action flow represents a series of actions taken by one of the users navigating the application's user interface during a session. A data structure is generated from the plurality of action flows. That data structure is indicative of a plurality of candidate sub-flows. The data structure is analyzed to identify a selected one of the candidate sub-flows repeated in multiple ones of the plurality of action flows. That identified sub-flow is the common action flow. Data representative of the identified common action flow can then be communicated.

Abstract: Methods, computer-readable mediums and systems for reducing transistor recovery are disclosed. Data which toggles at least one bit may be periodically communicated over a data path, where toggling of at least one bit may effectively reset the recovery period for any transistors in the data path associated with the at least one bit. Timing uncertainty associated with a given transistor may be reduced by limiting the amount of recovery experienced by the transistor. Accordingly, recovery of transistors in a data path may be limited to predetermined amount by toggling bits of the data path at a predetermined frequency, thereby reducing timing uncertainty and allowing a smaller system margin and/or higher data transmission speeds.
