In computing, a locale is a set of parameters that defines the user's language, country and any special variant preferences that the user wants to see in their user interface.
The Articles of Confederation failed because they did not give Congress and the national government enough power. The new United States just fought a war to end what they considered tyrannical rule of a strong government that overpowered local government and the leaders of the U.S. feared a powerful central government.
Those are the four major problems with the articles of Confederation. The Articles had problems with Currency, Interstate Commerce, Foreign Trade, and Foreign Affairs. The problem with the Currency was that many states printed their own money so the national currency became almost worthless.
