Abstract: A method for reconciling data includes separating a first table into a plurality of first chunks, each first chunk including a plurality of first rows, and second table into a plurality of second chunks, each second chunk including a plurality of second rows. Each second chunk corresponds a first chunk. For each first chunk, the method includes: computing a first hash based on the first chunk and a second hash based on a second chunk corresponding to the first chunk; comparing the first hash with the second hash; in response to the first hash being different from the second hash, retrieving the plurality of first rows and the plurality of second rows and comparing the plurality of first rows to the plurality of second rows; in response to the first rows being different from the second rows, generating executable code configured to reconcile the first table with the second table.

Abstract: A tubular receiver is open at an upper end and integral with a flexible sheet magnet, suction cup or other attachment device, at a lower end. A rod is frictionally inserted into the tubular receiver and extends upwardly to terminate with a spherical shape. When one of these devices is fixed to hitch portions of a trailer and a towing vehicle, the driver of the vehicle is able, more easily, to bring the two hitch portions together.
