Abstract: A device implementing drag and drop for touchscreen devices may include a processor configured to detect a drag gesture selecting an item in a first application. The processor may be further configured to detect a touch release at an end of the drag gesture for dropping the item in a second application, and send, in response to the detected touch release, a message to the second application, the message including information for a plurality of representations of the item. The processor may be further configured to receive, from the second application, a request for a representation of the item from among the plurality of representations. The processor may be further configured to send, to the first application, the request for the representation of the item. The processor may be further configured to initiate a data transfer of the representation of the item from the first application to the second application.

Abstract: The subject technology provides for identifying an item being dragged over an application in which the items are arranged in a table in a first arrangement. The subject technology copies the first arrangement to generate a second arrangement that corresponds to an initial arrangement of the items when the item is identified as being dragged over the first application. The subject technology updates the first arrangement to reflect changed positions of the items in the table resulting from another item being inserted into the table. The subject technology updates the second arrangement to reflect changed positions of items. Further, the subject technology merges the updated second arrangement with the updated first arrangement to reconcile the changed positions resulting from the item being inserted into the table at the location with the changed positions resulting from the another item being inserted into the table.

Abstract: An electronic device, while displaying a user interface for a first application, receives at the first application information that describes a first touch detected at a location on the touch-sensitive surface that corresponds to a respective user interface object. In accordance with a determination that the first touch meets predefined criteria associated with initiating a respective type of interface operation, the device initiates a user interface operation of the respective type involving the respective user interface object. The first application receives instructions to ignore the first touch with respect to user interface operations other than the respective type of interface operation, and ignores the first touch with respect to user interface operations other than the respective type of interface operation. In some embodiments, the respective type of interface operation is a drag operation, for dragging an object in or from a view of the first application.

Abstract: Methods, devices, and system for providing anonymous guest players for multiplayer applications are described. In one embodiment, a computer-implemented method includes initiating a game service for playing a multiplayer gaming application on a system, providing with a multiplayer API functionality for defining and adding an anonymous guest player to the system, generating data including a gaming invite that provides an ability to invite one or more friends that are registered with the game service and one or more anonymous guest players that are not registered with the game service. The method further includes receiving an input that identifies or selects an anonymous guest player to invite to play the multi-player gaming application on the system. The computer-implemented method further includes receiving data intended for the anonymous guest player from a different system of the multiplayer gaming application for peer to peer gaming applications.

Abstract: A computer implemented method for identifying aberrant behavior of a financial instrument including: retrieving from a source of market data, closing price, volume and number of transactions conducted for the financial instrument in a selected trading session; recording in computer memory, the closing price, volume and number of transactions conducted for the financial instrument in the selected trading session; identifying a plurality of time periods of different sizes, each of said time periods terminating with the trading session of the financial instrument immediately preceding the selected trading session; obtaining and recording the average and standard deviation of the closing price, volume and number of transactions during each of the time periods; determining whether each of the closing price, volume and number of transactions differs from the average of the corresponding component during each of the time periods by a selected number of standard deviations and for each case in which such a difference
