Basics

• What is open source?

4
Basics

• What is open source?
• Literally open source disclosed to public
• Refers to intellectual property not just code
• Open does not mean free to use (although it
  often is)
• Open does not mean free to call your own
• It means relaxed or non-existent restrictions
• Developer discretion!
• So who cares if its open?
• Developer perspective
• User perspective

5
Basics

• Who is using open source software?

6
Basics

• Who is using open source software?
• Probably everyone in this classroom
• Organizations and businesses of all sizes and
  types
• Schools and universities
• Governments
• Why are they using it?

• Probably everyone in this classroom
• Organizations and businesses of all sizes and
  types
• Schools and universities
• Governments
• Why are they using it?
• Often free with no up front and recurring fees
• Security
• Ability to improve/contribute

Basics

• Who is developing open source software?

9
Basics

• Who is developing open source software?
• Everyday people all over the world
• People with time and a passion for inventing,
  improving and then sharing
• Companies/orgs that sell services, not packaged
  SW
• Code and monetary contributions
• IBM, Google, Refractions Research, DM Solutions
• Anyone that cant afford proprietary software
