Open Source for academics.

2. Outline
 What is Open Source?
 Who runs open source projects?
 Why open source?
 Business models
 Contributing to open source.
 Why to contribute?
 What benefit student or professional gets out of it?
 Adopting Open Source in academics.
 Resources

3. What is Open Source?
 “The practice of providing open-source code for a
product; Open-source software in general; To make
open-source”
 Free sharing of technological information like
cooking recipes have been shared since the
beginning of human culture. Sharing cooking recipe
does not mean sharing cooked food.

4. Why open source?
 FLOSS potentially saves industry over 36% in software
R&D investment that can result in increased profits or be
more usefully spent in further innovation.
 No code is good code, there is always scope for
improvement and human limit may restrict the growth of
your project, so open the source.
 To make your code world class.
 Open source software projects may offer a learning
opportunity those students aren't getting in school.
 The best run open source projects have real standards,
and teams of experienced programmers.

8. Why they contribute?
 Companies like IBM, Intel, SGI, MIPS, Freescale, HP, etc. -- to
ensure that Linux runs well on their hardware.
 Distributors like Red Hat, Novell, and CentOS, Ubuntu have a
clear interest in making Linux as capable as it can be.
 Companies like Sony, Nokia, and Samsung ship Linux as a
component of products like video cameras, television sets,
and mobile telephones.
 VMWare - built on Linux kernel.
 Nvidia – Interested in Graphics business.
 Intel – Processor family interest
 Google – Run many Linux based servers in house.
 Volkswagen?

9. Why do people contribute?
“Human beings have an inherent tendency to seek out
novelty and challenges, to extend and exercise their
capacities, to explore, and to learn.”
Daniel H. Pink (Author of DRiVE - What motivates us?)

10. Why students/we should contribute to
Open Source?
You get :
 Good developers have always known that the way to improve is by reading
well-written programs. Good FOSS projects in dynamic communities provide
a wealth of examples for students to read, understand, and work on.
 Chance to interact with world class software team.
 Chance to read, modify or improve world class source code.
 Learn from constructive feedback of mature, well-run FOSS project team
 Learn project management.
 Essential professional software development skills that are seldom well-
taught in formal school settings.
 Learning Communications and social skills.
 Participation in FOSS projects can generate a very public portfolio of
practical work. This beats a resume any day. It also makes it easier to show
your previous work to a potential employer.

11. Business models
 Open source software can be sold and used
commercially.
 Donations?
 Saas? Iaas?
 Though there are FOSS apps around developed by big
companies, Open source does not always means free of
cost.
 You can charge/sell your software along with source
code.
 You can distribute it free and charge for Support.
 Important: First understand the Licensing in depth and
then go with business.

12. Examples
 Canonical Ltd. offers Ubuntu for free, while they sell
commercial technical support contracts.
 Mozilla Foundation have a partnership with Google and
other companies which provides revenue for inclusion of
search engines in Mozilla Firefox.
 MySQL is offered for free, but with the enterprise
version includes support and additional features.
 Novell offers openSUSE for free through the openSUSE
Project, while selling SUSE Linux Enterprise (SLE).
 Red Hat offers the Fedora for free through the Fedora
Project, while selling Red Hat Enterprise Linux (RHEL).
 Oracle offers OpenOffice.org for free, while selling
StarOffice.

14. So do you ...
 use good quality FOSS every day?
 like the freedom and openness of the Internet?
 think that Internet content should remain free?
 share stuff with your friends for free?
BUT
 Did you know that all (a lot) of this stuff is based
on...
FOSS ?

15. You use Open Source Software every
day.
 When you e-mail a document, pay your taxes online,
book an airline flight or do a search for a long lost
relative, you’ve just used open-source software.
 Every startup has access to the same technology that
only large enterprises could afford in the past.

16. Business Models using Open Source?
 Come up with a distinctive practical idea.
 See if there is any work done towards it in open source projects.
 If yes, See how can you adopt it and make it compatible with your
idea?
 If not, start a new open source project
 Every tool is available there starting from kernel, filesystem to web
server, open source social network platform find ways to adopt it to
your idea.
 CMS (Content Management Systems) – Drupal, Wordpress, Open
Cart, MediaWiki and many more.
 Open Source consultancy to SMEs or individuals.
 Open source training.
 Hosted Services – Cloud, Virtualization based infrastructure.
 Saas or Iaas

17. HOW OPEN SOURCE CAN
PLAY BIG ROLE IN
ACADEMICS?

18. Open educational resources

19. So how to get started?
 OSS Watch is an advisory committee which provides
comprehensive analyses of the legal, technical, and
economic aspects of open source software
implementation in the higher education sector.
 http://www.oss-watch.ac.uk/
 Open educational resources are online resources that
provide free applications and learning materials for
academic institutions. includes complete course materials,
modules, journals, reference materials. These resources
can be modified and redistributed.
