Abstract: Techniques for spread and pinch gestures are described. A spread gesture can be recognized effective to cause an item to be duplicated. In implementations, the spread gesture includes at least two inputs that select the item and spread apart to increase a distance between the two inputs. The item is divided into two substantially identical items in response to the distance between the two inputs exceeding a distance threshold. A pinch gesture can also be recognized effective to cause one or more items to be removed from a display of items. In implementations, the pinch gesture includes two or more inputs that select and drag two non-adjacent items toward one another to decrease a distance between the two non-adjacent items. The one or more items that are between the two non-adjacent items are removed from the display based on recognition of the pinch gesture.

Abstract: Presented here are systems and methods to enable software applications to display images on irregular screen shapes containing the shape without display functionality. In one embodiment, the shape without display functionality is confined within a bounding shape, which, when subtracted from the irregular screen shape leaves a rectangular area of the screen where the image can be displayed.

In another embodiment, the image can be displayed on the full irregular screen, such that the shape without display functionality covers a part of the image. When the occluded part of the image contains a critical object, such as a menu item, a button, etc., the image can be modified to move the critical object out of the area occluded by the shape without display functionality.

The multiple data fragments of data sets are prevented from routing to the same storage devices by a multi-step selection protocol which selects (in a first phase of the selection routine) a healthy highest ranked drive enclosure, and further selects (in a second phase of the selection routine) a healthy highest-ranked data storage controller residing in the selected drive enclosure, for routing data fragments to different storage pools assigned to the selected data storage devices for exclusive “writing” and data modification. The selection protocol also contemplates various failure scenarios in a data placement collision free manner.
