Set of slides prepared for a debate on the topic for Imperial Institute of Higher Education.

1. Debate conducted at Imperial Institute of Higher
Education

2. "To be able to choose between proprietary software
packages is to be able to choose your master.
Freedom means not having a master. And in
the area of computing, freedom means not using
proprietary software."
-Richard M. Stallman

3. Game Plan – Round 1
 What’s Open Source?
 How to Open Source?
 Open Source squashes Proprietary

5. What’s Open Source? –
opensource.org
NOT ONLY access to the source code… but also,
 Free Redistribution
 Source Code
 Derived Works
 Integrity of the Author’s Source Code
 No Discrimination Against Persons or Groups
 No Discrimination Against Fields of Endeavor
 Distribution of License
 License Must Not Be Specific to a Product
 License Must Not Restrict Other Software
 License Must Be Technology-Neutral

7. Licensing
 Open Source SW – SW distributed under the license
which follows the Open Source definition
 How to choose a license?
 Do you wish to give control of your code to others?
 Do you want to allow people to use your code in non open-source
programs?
 If somebody uses your code in their program and sells their program for
money, do you want some of that money?
 If somebody uses and distributes your code and improves it (fixes bugs
or adds features) do you want to make them give you the improvements
back so you can use them too?

9. Battle of Choices
Criteria Public BSD/ ASLv2 GPL LGPL MPL/ CPL/
Domain MIT (Apache) (v2) CDDL EPL
Code is protected by No Yes Yes Yes Yes Yes Yes
copyright?
Code can be used in Yes Yes Yes No Yes Yes Yes
closed source projects?
Program that Yes Yes Yes No Yes Yes Yes
uses (incorporates) the
software can be sold
commercially?
Source to bug fixes and No No No Yes Yes Yes Yes
modifications must be
released?
Provides explicit patent No No Yes No No Yes Yes
license?

11. The Hits
Open Source Proprietary
Customizability/Modifiability -> Better Limited Flexibility
Fit
Low Cost High Cost
Tight security Comparatively Less Secure
More Innovation Limited to the innovation of the few
internal developers

14. Continuing to Strike – Open Source
 Adaption of New Trends Faster
 Promotion of Re-Distribution

17. Why Open Source?

18. When users don't control the program, the program controls
the users.
The developer controls the program, and through it controls the
users.
This non-free or “proprietary” program is therefore an
instrument of unjust power.

19. Game Plan – Round 3
 Current Track Record
 Future of Open Source

21. Government Arena
 In December 2000, the NSA publicly announced the
development and release of Security-Enhanced Linux
“we recognized that open-source had tremendous
potential within government technology systems.”
~ National Security Agency (NSA) of USA
 “Too many government IT projects have failed because
they started without testing whether the end product
was feasible”.
~ Mark O’Neill, head of innovation and delivery in the Government Digital
Service (GDS), UK

22. Microsoft going Open Source
 Open Sourcing ASP.NET MVC4.0, WebAPI and Razor View Engine
 Becoming A Top-20 Contributor To The Linux Kernel
 Supporting open-source platforms in Azure
 Supporting Apache, PHP and Ruby on Windows
 Making Windows a great platform for open-source
 Wheel-Reinventing Reduced
 Including JQuery and Modernizr in ASP.NET MVC 3.0

24. Survey – 30th May 2012
 740 questioned
 59% non vendors
 41% OSS vendors
 62% use OSS and platforms
 1/3rd – More than 75% OSS deployments
 Adoption rate of OSS in non-technical arenas increased by 42%
 Enterprise – 40%
 Automotive Industry – 59% deployments
 More than 50% SW acquired in the next 5 years will be Open Source

27. Reasons for the Choice
 Free from vendor lock-ins
 Low Cost
 Better Quality
“The quality of open source, and the ability to continuously improve, is
now one of the top reasons for its adoption”
