Software libre como elemento necesario para la democracia de la multitud (Otros Temas)

En los textos de Empire y Multitude, Antonio Negri y Michael Hardt proponen que en el mundo actual la fuerza dominante que controla el capitalismo, y así el poder, es el Imperio. El Imperio obtiene su fuerza a través del control de la producción intelectual y su poder está ere cien - do durante este período de transición en el modelo capitalista. En este ensayo, se argumenta que los oprimidos por el Imperio, quienes conforman como clase la multitud, necesitan el software libre para crear su sueño: la democracia. Este software es a la vez el mejor ejemplo de como puede ser la democracia y una herramienta que permite la ampliación de ella. Además, su potencial en la región andina es todavía mayor por la debilidad del modelo de democracia liberal que promociona el Imperio.

A data collection case study supporting requirements oriented prediction and management in software developments

Consider the statement "this project should cost X and has risk of Y". Such statements are used daily in industry as the basis for making decisions. The work reported here is part of a study aimed at providing a rational and pragmatic basis for such statements. Of particular interest are predictions made in the requirements and early phases of projects. A preliminary model has been constructed using Bayesian Belief Networks and in support of this, a programme to collect and study data during the execution of various software development projects commenced in May 2002. The data collection programme is undertaken under the constraints of a commercial industrial regime of multiple concurrent small to medium scale software development projects. Guided by pragmatism, the work is predicated on the use of data that can be collected readily by project managers; including expert judgements, effort, elapsed times and metrics collected within each project.

Evolution in software systems: foundations of the SPE classification scheme

The SPE taxonomy of evolving software systems, first proposed by Lehman in 1980, is re-examined in this work. The primary concepts of software evolution are related to generic theories of evolution, particularly Dawkins' concept of a replicator, to the hermeneutic tradition in philosophy and to Kuhn's concept of paradigm. These concepts provide the foundations that are needed for understanding the phenomenon of software evolution and for refining the definitions of the SPE categories. In particular, this work argues that a software system should be defined as of type P if its controlling stakeholders have made a strategic decision that the system must comply with a single paradigm in its representation of domain knowledge. The proposed refinement of SPE is expected to provide a more productive basis for developing testable hypotheses and models about possible differences in the evolution of E- and P-type systems than is provided by the original scheme.
