Abstract: The current document is directed to methods and subsystems within computing systems, including distributed computing systems that efficiently store metric data by approximating a sequence of time-associated data values with one or more linear functions. In a described implementation, a running variability metric is used to control variation within the metric data with respect to the approximating linear functions, with a variation threshold employed to maximize the number of data points represented by a given linear function while ensuring that the variation of the data with respect to the given linear function does not exceed a threshold value. In one implementation, the metric data occurs within a graph-like configuration-management-database representation of the current state of a computer system.

Abstract: A finger cover for use with capacitive touchscreens devices is described. The finger cover includes a flexible rear panel having opposing sides between ends of the flexible rear panel, defining a length of the flexible rear panel, at least equal to the distance measured between the tip and the first joint of the user's finger. The rear panel has a width generally equal to one half the circumference of the user's finger. An elastic band connects opposing sides of the rear panel at a location near the first joint of the user's finger. An electrically conductive panel joins the opposing sides of the rear panel, joins the rear panel along the first end and joins the elastic band.
