Independent and stable software

<section begin=Abstract />

Currently the proprietary software is very widespread in our society. With the use of capital it is possible to influence and control the people by advertisement in this branche. Thereby it is possible to reach a big perception and acceptance. But what about crises? Data centers are down, and the dependence to the proprietary software makes it nearly impossible to find a new job in another company, because every firm uses another system and the workers are trained to utilize the specific programs. Furthermore another problem could be that the states collapse. One way to be independent is to employ with alternatives. The idea of open source is to provide all the knowledge to all the people. There are creative commons, open hardware and an open source software, which is not worse than proprietary projects. This is confirmed by the company "Coverity". They analysed the code from open source and proprietary schemes and the results are not lying. They show that open source had fewer errors per thousand lines of code (KLoC) than proprietary software. A good quality software has a defect density less than 1.0. The defect density was 0.59 for open source C/C++ projects and 0.72 for proprietary C/C++ code developed for enterprise level projects[text source 1]. And it is important to have a stable operating system. Recently there is one more popular open source operating system which is called Ubuntu. With the release of the server edition of its Linux distribution, Canonical will emphasize on how it can be used for organizations as the base for running large mission-critical applications in hosted environments. The latest version 14.04 has been released with long-term that means, that five years of patching and support will be included [text source 2] . All in all through open software people keep their independence.
