Abstract: Managing data in a computing device is disclosed, including generating reverse delta updates during an apply operation of a forward delta update. A method includes operations of applying forward update data to an original data object to generate an updated data object from the original data object and generating, during the applying, reverse update data, the reverse update data configured to reverse effects of the forward update data and restore the original data object from the updated data object.

Abstract: A computing device may include at least one primary notification module and at least one secondary notification module. A notification controller module may trigger a primary notification module and a secondary notification module to generate notification messages or the controller module may trigger the primary notification module to generate a notification message. A graphics device may generate a composite notification message based at least in part on the notification messages from the primary and the secondary notification modules, where representations of the notification messages are stacked one on-top of the other in the composite notification message.

Abstract: Techniques involving a simulated start-up or “boot” process to detect the introduction of unauthorized code or data into the boot process. In one embodiment, a boot process is performed to initiate a computing system. The boot process is then simulated using the initiated computing system to detect unauthorized modifications introduced into the computing system prior to the computing system's operating system being operational.
