Abstract: A system, a method, and a machine-readable medium for overclocking a computer system is provided. An example of a method for overclocking a computer system includes predicting a stable operating frequency for a central processing unit (CPU) in a target system based, at least in part, on a model generated from data collected for a test system. An operating frequency for the CPU is adjusted to the stable operating frequency. A benchmark test is run to confirm that the CPU is operating within limits.

Abstract: Constituent electronic devices such as eBook reader devices may be combined to form a composite device. Resources such as power, data, processing capabilities, network interfaces, displays, and so forth may be shared between the constituent devices. Resources may also be allocated and transferred to increase operational time of depleted individual electronic devices. Content may be presented across the constituent devices of the composite device. A relative spatial arrangement of the composite devices may be determined to facilitate the presentation.

Abstract: An electronic book reader device leverages a secondary device via an ad hoc network connection to enhance user experience as the user is consuming content on the electronic book reader device. In particular, the secondary device may be equipped with a touch screen and notepad functionality, which may be leveraged to receive user input with respect to content being presented on the electronic book reader device. The user input may take any number of forms, including freeform entry of information (e.g., read notes), control commands, highlights, and so forth.

Abstract: A client device may include various sensors that monitor an environment of the client device as well as operations performed by the client device. The client device may identify a digital item that a user has requested to download to the client device according to a predetermined schedule that includes multiple reoccurring periods. The client device may monitor access of the item (or versions thereof) by the user for each of the multiple reoccurring periods of the predetermined schedule. The client device may then determine that the user does not access the item during at least one instance of a particular period of the multiple reoccurring periods. Based at least in part on the determining, the client device may refrain from downloading the item to the client device during an instance of the particular period that is subsequent to the at least one instance of the particular period.

Abstract: A client device may include various sensors that monitor an environment of the client device as well as operations performed by the client device. The sensors may sense data that, when analyzed and compared to past events and patterns, may be used to identify a current user of the client device. In some aspects, the data may be used to determine a context of operation of the client device, which may enable the client device to adapt in real-time or to predict future behavior of a user and then adjust control settings of the client device accordingly.
