Abstract: The description is directed to systems and methods for restoring a program state retained from a prior execution session on a virtual machine. On receiving a request to execute a program an image of user-independent files are mounted to a virtual machine. Specified user-modifiable files are copied from a particular user storage location to put the program in a condition to execute the program so that it begins from the previously-existing program state. During the session at least some of the files are modified and on a session end the user-modifiable files are saved to the particular user storage location to retain the updated program state.

Abstract: This disclosure relates to the field of identification devices. Embodiments include a shoelace, near the center of which is affixed a flexible strip, made from textile, plastic, or other suitable material, that is adapted to be wrapped about the shoelace and retained in that position. Desired information, such as name, address, telephone number, blood type, medical facts of special concern, or the like, may appear on the surface of the strip which is to be concealed by the strip having been overlaid by itself as it is wrapped about the shoelace. The strip, so marked and so positioned, may be surrounded by a protective cover material, such as a short, tubular segment of clear plastic, to protect the strip while keeping the distinguishing indicia visible. Such protective cover and/or the surface of the strip which is exposed when the strip is so wrapped may include distinguishing indicia to notify interested persons, such as police, medical workers, etc., of the existence of the enclosed information.
