Abstract: A debugger traps a module load operation and computes a hash of the loaded module. The hash is compared with a hash of a module file, and a warning is issued if the checksums are different. Systems and software implementing similar methods are also described and claimed.

Abstract: A digitized topology data compression and decompression method provides the digitized topology data of a collection of segments connected to each other via nodes. The method forms at least one composite line representing a chain of connected segments, which reduces an overall number of lines needed to represent the collection of segments and where each composite line has two end points at known coordinates, resulting in compression of the topology data. The method further represents each composite line by its respective end point coordinates. Next, the method enrolls each composite line into one of at least two sets of composite lines for minimizing a number of intersections between each of the composite lines within each of the sets of composite lines. Finally, the method reconstructs the nodes at a decompression time by calculating coordinates of intersecting composite lines belonging to different sets of composite lines.
