Open Source Software

• Open source software is computer software for which the human-

readable source code is made available under a copyright license (or arrangement such as the public domain) that meets the Open Source Definition. This permits users to use, change, and improve the software, and to redistribute it in modified or unmodified form. It is often developed in a public, collaborative manner.

Community Development• Open Source development allows individuals to contribute to any project

that interests them• Contributions can include both software development and testing• These contributors become the project’s “community”

“People just self select to do projects where they have expertise and interest”

– Linus Torvalds, The Originator of Linux


Open Source vs. Proprietary(from Bruce Guptill, Saugatuck Technology)

• Disruptive Elements – An ability to customize and use the software

code to whatever extent required and useful– Reduced dependence upon software vendor

technologies, license schemes, and maintenance/support requirements

– Enables low cost commercial offerings based upon open source software
