Abstract: A stringed instrument, such as a violin, viola, cello, or double bass, having an inherently flat back and an inherently flat top separated by a rib structure. An interior soundpost spans between the back and the top. A bridge supports the strings over the top. When tension is applied in the strings such that the bridge applies force to the top and the soundpost applies force to the back, the top acquires a concave shape and the back acquires a convex shape. In a particular embodiment, the instrument has retaining rings mounted on interior surfaces of the back and top keep the soundpost from falling over, two subassemblies interconnected by an adjustable screw-and-nut arrangement to achieve different string heights, a nut opening configured to receive differently sized top nuts for different string heights, and an inherently straight bass bar, where the bridge has feet having inherently collinear bottoms.

Abstract: Aspects of the present disclosure relate to predictive screen recording. In examples, a user initiates screen recording, such that an initial recording region is recorded. During screen recording, one or more events, user inputs, and/or any of a variety of other features are processed to generate a predicted recording region, which is used to update the region for which screen recording output is generated accordingly. Thus, the recorded region of the screen may change dynamically, thereby reducing the amount of postprocessing, planning, and computing resources that would otherwise be associated with recording the screen of a computing device, among other examples.
