Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, to adapt a communication service are disclosed. In one aspect, a method includes the actions of maintaining, by a computing device, a communication service that is accessible through a first user interface. The actions further include determining, by the computing device, characteristics of a user who has access to the first user interface. The actions further include, based on the characteristics of the user who has access to the first user interface, determining, by the computing device, a second user interface that is configured to access the communication service. The actions further include providing, by the computing device, the user access to the second user interface that is configured to access the communication service.

Abstract: The present invention is a rifle sling for use with a rifle having butt and barrel portions. The rifle sling comprises a one-piece leather strap comprising a central longitudinal axis, a fixed end portion, and a sliding end portion. The sliding end portion comprises a slit that is parallel to the central longitudinal axis of the strap. The sliding end portion being folded to form first and twisted second loops with the first loop passing thru the second loop to form a sliding knot. The fixed end portion comprises first and second slits parallel to the central longitudinal axis and aligned with each other. The fixed end portion being folded to form a loop that is passed thru the first and second slits to form a fixed knot. Unlike conventional rifle slings, the rifle sling of the present invention does not employ any hardware.
