close to $6.1 billion USD to develop Debian 3.0. In addition, we offer both an analysis of the programming languages used in the distribution (C amounts for about 65%, C++ for about 12%, Shell for about numbers and how they should be understood, and some comparisons with Red Hat Linux and other operating systems, both free and proprietary. To finish, we include some conclusions and references. 2 Some background problems are made available for stable releases on a daily basis so that users can maintain their systems secure and as bug-free as possible. Debian is unique for many reasons. Its dedication to free software

abstract software entity, and accidental tasks, the representation of the abstract entities in programming languages and the mapping of these onto machine languages within space and speed constraints have made the accidental tasks inordinately hard, such as severe hardware constraints, awkward programming languages, lack of machine time. How much of what software engineers now do is still devoted establishing software requirements • Growing software organically, adding more and more functions to systems as they are run, used, and tested”Who said it?Frederick Brooks Jr. • Joined IBM in 1956 • Manager
