The document discusses a seminar on open source and free software. It defines open source software as software distributed with its source code. It provides a brief history of open source software including the development of UNIX, the founding of the Free Software Foundation, and the release of Linux. It also discusses the key freedoms of free and open source software including the freedom to use, modify, and distribute the software. Examples of widely used open source software are also provided.

? Open Source??

5. Open Source Software is
distributed with
its
“source code”

COPIES

9. 1970: UNIX operating system developed at Bell Labs and by a
diverse group of contributors outside of Bell Labs.
1983: Richard Stallman founds the Free Software Foundation
1993: Linus Torvalds releases first version of Linux built
1997: Debian Free Software Guidelines released

10. HIGH LEVEL Translate in Assembly language Lower level

Improvements (as source code) and
Developer evaluation results: User as Developer

12. USE OF OPEN SOURCE SOFTWARE

13. Some Examples of OPEN SOURCE SOFTWARE
Operating Systems • Programming Tools
– Linux – Zope, and PHP.
– Android – Languages:
– FreeBSD, • Perl
OpenBSD, and • Python
NetBSD: • Ruby
• Internet • Tcl/Tk
– Apache, – GNU compilers and tools
– BIND • GCC
– Sendmail • Make
– Mozilla • Autoconf
– OpenSSL • Automake
• etc.

15. “Free software” is a matter of
liberty, not price.
Free software is a matter of the users’
freedom to
run, copy, distribute, study,change
and improve the software.

16. FOSS refers to four kinds of freedom :
• Freedom 0: The freedom to run the program, for any purpose.
• Freedom 1: The freedom to study how the program works, and adapt it to
your needs.
• Freedom 2: The freedom to redistribute copies so you can help your neighbor.
• Freedom 3: The freedom to improve the program, and release your
improvements to the public, so that the whole community benefits.

17. The GNU Project
The GNU Project is a free software
project, announced on 27 September
1983, by Richard Stallman at MIT.
("GNU" stands for "GNU's Not
UNIX"). GNU system, a kernel, was
filled by the third-party Linux Kernel
being released as Free Software,
under version 2 of the GNU GPL.

18. FOSS Strengths
Ability to fit local needs
you can modify and enhance the software to more closely fit your own needs.
No restrictions on use
No restrictions on how the software is used and no invoices for each user license.
Low cost
No charge for the software itself. Pay only for needed support or any additional
products & services if required. Even then huge savings than commercial SW.
User-driven
you decide what features are important and deserve attention .
Reliability
Mature open-source code is as bulletproof as software ever gets.
No supplier lock-in
Open Source software allows you to access the source code for your applications
and store your data in open standard

19. Why Linux is Better ??
1.Forget about viruses.
2.Do not pay for Operating System.
3.Forget about Drivers.
4.Update all of your software with a single click.
5.Your system is stable.
6.Linux protects your computer

20. SO ARE YOU
READY
AS
KING?
Thanking You

21. Difference between OSS and FOSS
FOSS OSS
Open source merely means that the
Free can mean one of two things…
Source code is made available by
1.Free as in “free to be modified”
Developers and is not necessarily
2.Free as in “Cost Nothing”
“free to be modified” and “free as
in cost nothing”

22. USE OF OPEN SOURCE SOFTWARE
• 8,50,000 – Android phones running in Linux and 30,000 windows phone.
• 9 out of 10 of the Super Computer run in Linux.
• Google, twitter,facebook,amazon.com powered by Linux
• Since 2005, 8000 developers from 800 companies
• 15 milions lines of code.
• A new kernel comes out every 2-3 months.
