TL;DR: In this paper, a method and system for recovering from a failure of a processing node in a partitioned shared nothing database processing system are provided, where a pair of processing nodes having twin-tailed-connected nodes are connected to a storage device, and a third processing node runs a replacement database instance for the first database instance which was running on the first processing node prior to the failure.
Abstract: A method and system for recovering from a failure of a processing node in a partitioned shared nothing database processing system are provided. The processing system may include a pair of processing nodes having twin-tailed-connected thereto a storage device. A first processing node of the pair of processing nodes has a first database instance running thereon which accesses a first data partition on the storage device prior to the failure. Upon detection of the failure, access to the first data partition on the storage device is provided to a third, spare processing node through the second processing node of the pair of processing nodes. The third processing node runs a replacement database instance for the first database instance which was running on the first processing node prior to the failure thereof. The replacement database instance accesses the first data partition on the storage device through the second processing node, thereby recovering from the failure of the first processing node. Access to the first data partition may include using a virtual shared disk utility having a server portion on the second processing node and a client portion on the third processing node.

TL;DR: A load/unload device to remove the slider from the proximity of the magnetic recording surface of a disk in a disk drive whenever the disk is to be stopped is described in this paper.
Abstract: A load/unload device to remove the slider from the proximity of the magnetic recording surface of a disk in a disk drive whenever the disk is to be stopped. The load/unload device is a ramp-like wedge which extends generally radially from the center of the magnetic disk and to the magnetic recording surface of the magnetic disk. When the slider is moved toward the center of the disk by an actuator mechanism, the end of the load arm supporting the slider, referred to as a tang, will engage the inclined plane of the wedge and lift the slider from the surface of the magnetic disk as the slider is translated closer to the center of the disk. Once the slider has been removed from close proximity of the disk, the tang may engage a trough-like surface on the structure supporting the wedge and will effectively detent the position of the slider through the forces exerted on the tang by the load beam of the actuator. Thus the disk will be protected from undesirable and damaging impacts of the slider against the magnetic recording surface of the disk thereby prolonging disk utility.

17 Sep 2012TL;DR: In this paper, a user viewing an application page on an interface of a computing device can leave the application page and navigate to the home page with a single hand gesture, which can be subsequently used to navigate the user to a higher functional level, such as a network level, a disk utility level, and the like.
Abstract: Various embodiments enable a user to navigate between various hierarchical or functional levels of a computing device by providing a hand gesture, such as a multiple finger pinch or splay. For example, a user viewing an application page on an interface of a computing device can leave the application page and navigate to the home page with a single hand gesture. Accordingly, the same hand gesture could be subsequently used to navigate the user to a higher functional level, such as a network level, a disk utility level, and the like. A multiple finger pinch or splay can also be utilized as a trigger to reveal an application's chrome, reveal running applications, provide a short-cut to accessing favorite applications or notes, or to provide alternative views or organization schemes for applications, documents, and the like.

TL;DR: Files are what make the world of Linux go round, and they’re the currency of any kind of operating system.
Abstract: Files are what make the world of Linux go round. They’re the currency of any kind of operating system, because every time you use your computer, you generate new files, even if they’re only temporary.
