What is open source exactly and why it exists?

Wiktionary definition:

• “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.

3

Why open source?

• Making Linux GPL'd was definitely the best thing I ever did.

• Linus Torvalds

• 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.

Why they contribute?

• Companies like IBM, Intel, SGI, MIPS, Freescale, HP, etc. -- to ensure that

Linux runs well on their hardware.

What do I get as a student out of it?

You get :

• Chance to interact with world class software team.

• Chance to modify or improve world class source code.

• Come out with better skills than students who only do the required class

work.

• Learn from professionals.

• Build your resume stronger.

• Learn project management.

• Learn ins and out of Source code.

9

How do I Get Started ?

• Choose an area of your interest.

• Do your homework -- mailing list(s), a wiki, code repository; things done in

the past, things discussed on mailing list.

• "Be familiar with coding style, contribution practices, community email

etiquette, and copyright assignment practices for the project you are

contributing to." "Most of all, have fun! Don't be discouraged by strong

personalities in the community and try to understand other people’s

perspectives. "

• Reviewing code -- any competent developer appreciates more eyes on the

code.

• ASK questions

• Documentation as a comments inside source code

• Embedded Linux -- hot area for developers.

• Don’t forget to understand licensing.

10

Business models

• Open source software can be sold and used commercially.

• Donations?

• Saas? Iaas?

• Thought 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.

11

Few 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.

12

Examples contd …

• Zend Technologies offers Zend Server CE and Zend Framework for free,

but sells Zend Server with support and additional features.

• Wikipedia – Runs of donations. Sharing what we know for free.

• KQInfotech's ZFS port to Linux

• Infibeam?

13

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 ?

14

Hey, Come on! These are all big MNCs selling/supporting open source software, what is there for a student like

me?

15

Prodigies? 16

So how you too can be one among them?

• 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

Opportunities in India

• Ever growing Indian Market. • Indian government is going to create business opportunity

worth billions of dollars. •Web 2.0 or 3.0 – Ever growing Online business. Semantic Web

is next big thing. • Education? • Services. • Hosted services.
