nut is nutrition software to record what you eat and analyze your meals for nutrient composition. The database included is the latest USDA Nutrient Database for Standard Reference. This database contains values for vitamins, minerals, fats, calories, protein, carbohydrates, fiber, etc., and includes the essential polyunsaturated fats, Omega-3 and Omega-6. Nutrient levels are expressed as a percentage of the Daily Value, the familiar standard of food labeling in the United States, but also can be fully customized. Foods can be added from recipes or food labels, and nutrient intake can be graphed. The program is completely menu-driven and there are no commands to learn.
Fast File Validator (FFV) is a program for verifying files against a checksum file and for creating such checksum files. FFV supports both SFV files (which use the CRC32 algorithm) and MD5 files. "Checksum" is meant in the generic sense here. Technically, neither CRC32 nor MD5 is really a checksum.
