Github: a Case Study of Linux/BSD Perceptions from Microsoft's

This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software. In this study, development [10]. our aim is to explore these perceptions in FLOSS developers. We In this paper, we report on how external events such as conducted a survey that covered traditional FLOSS source Linux, acquisition of the open source platform by a closed source and BSD communities and received 246 developer responses. organization triggers a FLOSS developers such the Linux/ The results of the survey confirm that the free community did trigger some communities to move away from GitHub and raised BSD Free Software communities. discussions into free and open software on the GitHub platform. The study reminds us that although GitHub is influential and II. TARGET SUBJECTS AND SURVEY DESIGN trendy, it does not representative all FLOSS communities. -

Who “owns” Linux ? Where does Linux run ? Q&A What is Linux? LINUX is an operating system or a kernel distributed under an open-source license. Its functionality list is quite like UNIX. The kernel is a program at the heart of the Linux operating system that takes care of fundamental stuff, like letting hardware communicate with software. Who created Linux? Linux is an operating system or a kernel which germinated as an idea in the mind of young and bright Linus Torvalds when he was a computer science student. He used to work on the UNIX OS (proprietary software) and thought that it needed improvements. However, when his suggestions were rejected by the designers of UNIX, he thought of launching an OS which will be receptive to changes, modifications suggested by its users.
