Outline

3. Open Source Software (OSS) is software for
which the programming code is available to
the users so that they may:
◦ Copy it
◦ Study it
◦ Use it
◦ Modify it , and
◦ Redistribute it
Open Source Software

4.  Free Redistribution
The license shall not restrict any party from selling or
giving away the software. i.e. license shall not require a
royalty
 Source Code
The program must include source code, and must allow
distribution freely
 Derived Works
The license must allow modifications and derived works
 No Discrimination Against Persons or Groups
The license must not discriminate against any person or
group of persons.

5.  IBM
◦ Uses and develops Apache and Linux; created Secure
Mailer and created other software on AlphaWorks
 Apple
◦ Released core layers of Mac OS X Server as an open
source BSD operating system called Darwin;
 HP
◦ Uses and releases products running Linux
 Sun
◦ Uses Linux; supports some open source development
efforts(Forte IDE for Java and the Mozilla web browser)

6.  Red Hat Software
◦ Linux vendor
 ActiveState
◦ Develops and sells professional tools for Perl,
Python, and Tcl/tk developers.

7.  Freedom to use, study,
modify and share
scientific and creative
works

8.  O/S Linux
 Used in numerous domains, from embedded
systems to super computers, installation
with popular LAMP application pack.

9.  Developed and Maintained under Mozilla
Foundation.
 Available for a wide variety of OS.
 Most popular Web browser.

10.  Developed and maintained
under Mozilla Foundation.
 Available for a wide Variety
of Operating Systems.

11.  Originally derived from StarOffice,
developed by StarDivision
 Acquired by Sun Microsystems in
1999.

12.  Developed by Sun
Microsystems and open
sourced in November 2007
under GNU GPL.
 Used in a wide variety of
computing platforms
spanning from embedded
devices to enterprise servers
and supercomputers.

13.  Apache HTTP Server
 Developed and maintained under Apache
Software Foundation. Available for a
wide Variety of OS
 Most popular HTTP Server on WWW
 The majority of all web servers using
Apache are Linux web servers.
 Apache is characterized as free software
and open source software.

14.  RDBMS: MySQL
 Owned and sponsored by the Swedish
company MySQL AB, now subsidary of Sun
microsystems.
 Has more than 11 million installations.
Widely used to support websites.

15.  PHP is a scripting language originally designed
for producing dynamic web pages.
 Hypertext Preprocessor
 PHP is free software released under the PHP
License, however it is incompatible with the
GNU General Public License (GPL)
 PHP is commonly used as the P in this bundle
alongside Linux, Apache and MySQL, although
the P may also refer to Python or Perl.

16.  Joomla! is a free open source content
management system
 Used for publishing content on the World
Wide Web and intranets

19. Why Open Source?

20.  Linux has a failure rate of 8 % Where as
Microsoft has more that 56%
 No Viruses (User Space and kernel space is
separate)
 No Spyware
 Crash rate is almost negligible
Failure Rates & Threats

21. Open Source is Flexible
 The source code is available, so it can be altered to suit
your needs.
 A program can change in ways the author never
intended or dreamed of
Open Source is Cost Effective
 Support can become competitive; and therefore cheap!
 Cost sharing: many developers share the development
costs of the same product
Features of Open Source

22. Open Source Developers are motivated
 Programmers write better code
 They usually write code they need and want to write rather
than code they are assigned
More Security and less bugs
 Peer review allows bugs to be discovered and fixed early
 Viruses, “spyware,” etc. are almost non-existent!
The code will survive!
 While the loss of a major corporate contributor, it will
never mean the death of a piece of Open Source software.

23. Cost benefit University Level
 No of Colleges Under CSVTU = 40
 Expense of a college on OS & AV /year:
Rs. 6,00000/-
 Total Expense/Year University Level:
=>40 * 600000=2,40,00000/-
(We can save 2.40 Crore that we pay to Microsoft at University Level)

Solution is Open Source

27.  OSS becomes strategic tool for open and collaborative
businesses.
 50% of jobs in the information technology sector will
be linked to Open Source applications before 2019.
 By 2020, 50% of Global 2000 IT organizations will
implement a formal open-source adoption and
management policy.
Open Source Future .

28.  With economic slowdown
enterprises have started
optimizing their IT
budgets.
 Free and Open Source
software is being
adopted.
 They need employees
having familiarity with
Open Source
Technologies.

29.  Learn more about Free/Open Source
 Get trained in one or more of the Open
Source technologies.
 Install Open Source Software and start
experiments.
 Contribute for an Open Source Project
 Train others in Free/Open Source Software
