Analyzing open source systems: Unix OSThe open source concept is a very wide concept. It assembles many problems and concepts related to issues of intellectual knowledge, software design, collaboration, leadership, and motivation. The collaborative issue is the one that has been studied while examining open source systems because the aim of this type of systems is to be able to create of a sociological and technical environment where participants can collaboratively construct solutions to problems of mutual interest. This ideas has been the catalyst to create new educational activties related to open source projects. The analyze of open source project could also be the first step in applying the open source principles in the making of other projects based on collaborative construction. UNIX is an open source system that has proven to be much better than other operating systems and more adaptable to the end user because it is a creation of the users themselves. Advantages of Unix
Moreover, in the UNIX system's early days, security was virtually nonexistent. Subsequently, the UNIX system became the first operating system to suffer attacks mounted over the nascent Internet. As the UNIX system matured, however, the organization of security shifted from centralized to distributed authentication and authorization systems. Today, these perceptions are only of historical interest. Why secure?There are some design features in UNIX based system that tend to make UNIX systems intrinsically secure:
Unix operating system is an open source system that could be considered as an example of complex systems because it is made by communities that have common qualities. However, unlike complex systems, open source systems are characterized by the intention of the participants in it which lies in the wish of having an operating system that is perfomant and adaptable to changes. Briefly, Unix is an operating system (OS) whose license give users the freedom to run the OS for any purpose, to study and modify the OS, and to redistribute copies of either the original or modified OS (without having to pay royalties to previous developers). The creation of systems in which users can be designers is the main idea behind creating UNIX and therefore it illustrates meta-design. Our course for example is an environment where students are active contributors to their education through Swiki and Google..., and the envisionment and discovery collaboratory is an example of a system supporting meta-design (UNIX in this case). Unix relies deeply on active participation, and that's what makes it good, changeable and reliable. For our case, contributing to an open source project like Unix would be in the biggest educational benefit for us, and won't be hard to achieve. For everyone else, it is a great way to improve a product that they probably use and a great learning experience. Throughout this study, the benefit of how much people will learn after their contribution to an open source project, and how much back they could get out of it ( in terms of their ideas being heard...) decides why people in different contexts become involved in open source development.
