Abstract: A system and method of active latency detection for network applications that allows network latency to be calculated from a single host system. Periodic requests are generated from the host system and directed to a remote system in a way that requires minimal processing by the remote system. Latencies are calculated from the timing information associated with the periodic requests and can be combined with timing information associated with application packets to generate a latency trace for one or more network applications.

Abstract: A tool including a handle secured axially to a reversible face plate structure having a flat sheet metal body including a first portion with a half-round-curved edge or periphery adapted to fit into half-round gutters as well as a second portion with a more rectangular peripheral contour conforming or complementary to inner shape of so-called "K" type gutters. A free end of the handle has a truncated, tapered end portion. Additional light-duty uses or applications total at least twelve tasks for employment thereof including use of the tool as a weeder in a garden; a ditcher; a hoe; a spreader; a row-forming tool; a seed-bed tool; a furrowing tool; a deep planting tool for bulbs, sets and small plants; a blending tool for mortar or plaster; a hand tiller for mulch and dry chemicals or fertilizer; a hand tamping tool for soil or sand; a planting lateral-spacing-gauge tool; a planting depth-gauge tool; and as a scraper for dirt, mud, plaster, mortar and the like.
