Questions and Answers

What is the fundamental difference between Free Software and Open Source Software?

Free Software emphasizes the ethical principles of freedom and user rights, while Open Source Software focuses more on the practical benefits of open development and distribution models.

What is the significance of the GNU Project and the Free Software Foundation in the history of FOSS?

The GNU Project, started by Richard Stallman in 1983, aimed to create a completely free operating system called GNU. The Free Software Foundation was founded in 1985 to support the GNU Project and promote the philosophy of free software.

Explain the concept of 'copyleft' and how it differs from traditional copyright.

Copyleft is a principle that uses copyright law to ensure that derivative works of a software remain free and open source. It differs from traditional copyright, which restricts the modification and redistribution of software.

What is the economic rationale behind the 'zero marginal cost' principle in FOSS?

The 'zero marginal cost' principle refers to the fact that once a software is developed, the cost of distributing additional copies is essentially zero, enabling free distribution and widespread adoption. Signup and view all the answers

Study Notes

Introduction to Open Source and Free Software

Open Source and Free Software are related but distinct concepts
Free Software focuses on the freedom to use, modify, and distribute software
Open Source emphasizes the availability of the source code
Public Domain Software is not owned or copyrighted by anyone
FOSS (Free and Open Source Software) does not necessarily mean zero cost

History of Open Source

BSD (Berkeley Software Distribution) played a significant role in the early development of open source software
The Free Software Foundation and the GNU Project were founded to promote software freedom

Methodologies and Principles

Open Source Development Model is based on collaborative development and community involvement
Licenses and patents are essential in open source software development
Important FOSS licenses include Apache, BSD, GPL, and LGPL
Copyrights and copyleft licenses are used to protect and share software
Patents can be used to restrict or promote open source development

Economics of FOSS

Zero Marginal Cost: the cost of reproducing and distributing software is zero
Income-generation opportunities exist through support, services, and customization
Problems with traditional commercial software include high costs and limited customization

Open source software is used in government and public institutions
Open source ethics promote transparency, collaboration, and social responsibility
Social and financial impacts of open source technology include job creation and cost savings

Case Studies and Examples

Apache web server is an example of a successful open source project
GNU/Linux is an open source operating system
Android is an open source mobile operating system
Mozilla (Firefox) is an open source web browser
Wikipedia is an open source encyclopedia
Drupal and WordPress are open source content management systems
GCC and GDB are open source development tools
Open Office is an open source office suite
Free Design and Open Source Teaching are examples of open source applications

Collaboration and Community

Open source projects rely on collaboration and community involvement
GitHub is a platform for open source project collaboration
Introduction to Wikipedia and contributing to open source projects
Open source media and hardware are emerging areas of interest

Contributing to Open Source

Interacting with the community on GitHub involves communication, etiquette, and testing
Reporting issues and contributing code are essential skills for open source developers
Starting and maintaining open source projects requires planning, collaboration, and community engagement
