Abstract: A plunger for a dispenser for cartridges containing materials to be dispensed, for example viscous materials, is disclosed, the plunger having three plunger portions which define empty spaces therebetween so that cartridges, for example two-component concentric cartridges, of a plurality of dimensions and configurations can operatively mate with the plunger. A dispenser having a plunger as described can be used with a multitude of different cartridge types, including concentric two component cartridges or cylindrical single component cartridges, of varying overall dimensions and configurations. Also disclosed is a plunger for assisting the alignment of a cartridge in the dispenser. Corresponding dispensers and methods of loading cartridges are further disclosed.

Abstract: A system, method, and computer program product for distributed software code testing. When a data processing system is not being actively used, it will download and execute test code, and return the results to a server. This process increases the efficiency of code testing while exploiting otherwise-wasted processing power.

Abstract: A system, method, and computer program product for software code testing. By creating a coverage database that relates specific code portions to specific tests, the user or system can then determine which tests must be run for any code modification, and can run only those tests instead of the entire battery of tests.
