Abstract: An environmentally sound magnetic sink strainer with a magnetic post fits inside a kitchen sink drain opening flush below the surface of the bottom floor of the sink. In this sunken position, the bottom floor of the sink is horizontally flat, enabling a person to clean pots and pans positioned on the flat sink floor. The central operating magnetic post is attachable to a rubber stopper at the bottom of the sink strainer. As waste water with entrained magnetic steel wool debris passes into the strainer, the magnetic central operating post attracts and collects the debris, capturing it and preventing it's progression into the sink drain and trap. The magnetic post can be conveniently wiped by a paper towel or rag to dispose the metal steel wool debris collected as solid waste.

Abstract: A graphical user interface receives data in the form of a data block. The graphical user interface displays the data and metadata associated with the data block. The graphical user interface also displays validation information computed by the graphical user interface or an associated validation module. The displayed data is editable. The graphical user interface allows a user to navigate through the various data blocks stored in a data file, to located selected blocks, such a corrupted blocks.
