Abstract: The present disclosure provides systems and methods for content quasi-personalization or anonymized content retrieval via aggregated browsing history of a large plurality of devices, such as millions or billions of devices. A sparse matrix may be constructed from the aggregated browsing history, and dimensionally reduced, reducing entropy and providing anonymity for individual devices. Relevant content may be selected via quasi-personalized clusters representing similar browsing histories, without exposing individual device details to content providers.

Abstract: A mitten-shaped washcloth with a very coarse usable surface and a generally rough usable surface and having an inside lining and reinforcing lining border around an outer perimeter made of fabric is made by cutting a cylindrical loofah piece off a gourd, shortening it, slicing it open lengthwise to remove the interior, flattening it into a sheet of loofah, shaping it, cutting open a cavity for the hand and sewing the border and lining on easily.

Abstract: A two-sided washcloth is made of a sheet of loofah that is lined on an outside perimeter with cloth. The washcloth has a convenient set of parallel spaced-apart linear openings also lined with cloth. The surface area of the loofah between the linear openings together with the lining around the openings constitutes a holding area for pressing the back one's hand against after inserting four fingers of a person's hand through both linear openings. The grip is secured by maintaining the thumb on the near side of the first opening. The grip permits both sides of the sheet comprising the washcloth to be applied to the body conveniently, thereby assuring maximum use of the loofah.
