How did software evolve?Software was once free
People considered hacking as a
hobby, and freely exchanged code.

How did software evolve?Software was once free
People considered hacking as a hob

Then Bill Gates wrote a famous let

of stealing software!
He wanted to make it a commodity
which could be used to generate pro
fit.
A penny for your thoughts...
Physical items cost something because o
nce you give it to someone else, it's no lo
nger with you.
Are ideas, thoughts and ultimately softw
are the same?
Do you pay your college for sharing kno
wledge or for providing you infrastructure
and facilities?
Should ideas be patented or should it b
e shared?
What is Open Source?
1. Source Code Available
2. Free Redistribution of Code
3. Allows Derived Works
4. Allows Integrity of Author’s Source Code
5. No Discrimination Against Persons or
Groups
6. No Discrimination Against Fields of
Endeavour
7. Distribution of License Code
8. License Must Not Be Specific to a Product
9. License Must Not Restrict Other Software
10.License Must Be Technology-Neutral
Official Open Source Definition by Open Source
Initiative (OSI). Available at opensource.org/docs/osd
What is Free Software?
Freedom to run the software according to your
needs
Freedom to browse the source code and make
changes as you please
Freedom to distribute software
Freedom to make your changes available for
others to use
Free Software Foundation – fsf.org
Big Deal?
So what if it’s free?
?
Still not convinced? How about…
An Amazing, community driven way of
writing high quality software
A Collaboration of hundreds of people
from all over the world
Since you don’t need a degree to
contribute, its an opportunity for intelligent
developers even if they aren’t employed!
And the cost…?
Open Source is the Next Big
Thing…
Close to 90% of the top 500 companies in t
he world run the Linux Servers.
Companies prefer Open Source over
proprietary .
Governments Love Open Source .
Open Source is here to stay
What’s in it for me?
As students, access to the source code means y
ou learn more about how software works the wa
y it works.
You get to modify source code and experiment.
Who knows?
A change you make may benefit everyone.
Change the way you write code, for the best.
You can even get a Job!
The list is endless...
Giving back to the community...
Either contribute part time...
Or contribute full time (paid workers of comp
anies)...
I think you already know who falls in the firs
t category...
If you don't, then let me tell you…
How to contribute
Write patches, fix bugs for different projects and
contribute Code.
Start your own open source project!
Triage bugs for different projects
Contribute art work
Test software on your platforms and share your r
esults
Visit forums, ask questions and answer them if po
ssible
PARTICIPATE!!!
Why the move to open source?
Open Source has
vibrant ecosystem where everyone is playing
an active part.
There are no layers between the developer
s of a project and the customers and no hassl
e of customer care centres :)
Bugs gets fixed faster
NoVendor lockins or lockouts
