Teaching Open Source In The University
This document discusses teaching open source software in universities. It describes courses on operating systems and information security that incorporated open source tools and distributions like Ubuntu, Linux, Apache, and MySQL. Student surveys found initial resistance to unfamiliar open source environments but growing interest as they learned about licensing, business models, and development methodologies. The author reflects on lessons learned and ways to improve open source education, such as introducing version control earlier and allowing more flexibility for creative projects.

- 10. Software License ● a typical software license grants an end-user permission to use one or more copies of software in ways where such a use would otherwise constitute infringement of the software publisher's exclusive rights under copyright law ● the software license acts as a promise from the software publisher to not sue the end-user for engaging in activities that would normally be considered exclusive rights belonging to the software publisher
- 11. Proprietary Software License ● Software publisher grants a license to use one or more copies of software; however ● Ownership of those copies remains with the software publisher ● All rights are reserved by the software publisher ● Only a limited set of rights are given to the user ● User must accept the software license to use it
- 12. Open source softwarelicense ● Ownership of a particular copy of the software is transferred to the user ● End-user is granted the same rights as the copyright owner ● Extra rights may also be given to the user ● However, copyright ownership does not change; it remains with the publisher ● Acceptance of open source license is optional in order to use it ● However, exercising the additional rights requires acceptance of the license
