3. WHAT IS OPEN SOURCE ?
 In production and development, open source is a philosophy, or
a methodology that promotes free redistribution and access to
a product's design or ideas and implementation details.
 open as in free
 open as in access
 open as in over time
 open as in not closed
 open as in reuse and change
 open as in any place and for anyone

4. OPEN SOURCE VS. CLOSED
SOURCE
 View/Modify the source code of an application or software.
 Open source software is released to the development
community and undergoes a secondary phase of evolution,
but closed source software is developed in isolation with a
small team of developers.
 Developer support and large community to help.
 Open Source is more secure and bugs and vulnerabilities are
fixed often.

5. CRITERIA FOR OPEN SOURCE
 Source Code Availability
 Derived Works
 Free Redistribution
 Distribution of License

 No Discrimination Against Persons or Groups
 No Discrimination Against Fields of Endeavor

6. HOW OPEN SOURCE WORKS ?

7. ADVANTAGES OF OPEN SOURCE
 Availability of source code
 Source code to understand and learn from
 Do not have to re-invent the wheel
 Free as in “freedom”
 Does not depend on vendor
 Can choose additional support
 Can fix bugs and adapt to change in requirements as
well as technology
 Quality and Customizability in open source is better.
 Costs much less than proprietary counterparts.

8. SOME DISADVANTAGES OF OPEN SOURCE

 Author chooses to license under a licence granting open
source freedoms. Some are easy to comply with like :
 “You can do anything you like with this software, as long as you
buy me a drink sometime if we meet”.
 Some licenses are more difficult to comply with :
 GNU GPL says that you can only use GPL code if
modified/distributed code is also released under the GPL
 “Copyleft”
