   HISTORY OF OPEN SOURCE

4. HISTORY
   ▪ The term Open Source was adopted by a group of
   people held at Palo Alto, California. "Open Source
   Summit" organized in April 1998 by technology
   publisher Tim O'Reilly.

5. HISTORY
   ▪ The concept of free sharing of technological
   information existed long before computers.
   ▪ Similar to open standards, researchers with access to
   Advanced Research Projects Agency Network
   (ARPANET) used a process called Request for
   Comments to develop telecommunication network
   protocols which led to the birth of the INTERNET in
   1969

7. OPEN SOURCE
   ▪ “Open source" refers to something people can
   modify and share because its design is accessible
   public wide.
   ▪ Open Source technology can be defined as
   Computer Software for which the source code is
   made available under a copyright License(GPL),
   enabling anyone from anywhere to copy, modify and
   redistribute the source code without paying any fees.

8. OPEN SOURCE
   ▪ “Open Source” is a software-
   licensing model where the
   source code of the software
   is typically made available
   royalty-free to the users of
   the software, under terms
   allowing redistribution,
   modification and addition,
   though often with certain
   restrictions.

   ADVANTAGE OF OPEN SOURCE

10. ADVANTAGE
    ▪ Easier to customize
    ▪ You can modify the software to your specific needs –
    there’s a lot of control and eventually satisfaction .
    ▪ The availability of the source code and the right to
    modify it is very important.
    ▪ Global collaboration with skilled developers.
    ▪ Core software is free.
    ▪ Encourages hands on.

11. ADVANTAGE
    ▪ Learning - a newbie programmer with at least one
    year of solid programming education (even if it’s
    self-taught learning), contributing to an open source
    project can be one way to learn programming faster.

    DISADVANTAGE OF OPEN SOURCE
    12
    

    View Slide

13. DISADVANTAGE
    ▪ some Open Source projects stall and die -
    programmers just lose interest with being involved or
    they become fraught with infighting; arresting
    further development.
    ▪ It is sometimes difficult to know that a project exist,
    and its current status.
    ▪ Can lack software support and/or resources
    (documentations, communities, etc.)
    13
    

    View Slide

14. DISADVANTAGE
    ▪ Lack of time to really learn the software.
    ▪ May lack the manpower to support the software.
    ▪ Vulnerabilities - Although having an open system
    means that there are many people identifying bugs
    and fixing them, it also means that malicious users
    can potentially view it and exploit any vulnerabilities.

17. GNU General Public License (GPL)
    GPL is a copyleft license. This means that any software
    that is written based on any GPL component must be
    released as open source. The result is that any software
    that uses any GPL open source component (regardless
    of its percentage in the entire code) is required to
    release its full source code and all of the rights to
    modify and distribute the entire code.

18. The Apache License
    The Apache License allows you to freely use, modify,
    and distribute any Apache licensed product. However,
    while doing so, you’re required to follow the terms of
    the Apache License.

19. Microsoft Public Licenses (Ms-PL)
    The Microsoft Public License is a free and open source
    software license released by Microsoft, which wrote it
    for its projects that were released as open source.
    You are free to reproduce and distribute original or
    derivative works of any software licensed under the Ms-
    PL license. However, you may not use any contributors’
    name, logo, or trademarks when you do so the author is
    not liable if the code doesn’t work well in some cases.

20. Berkeley Software Distribution (BSD)
    The BSD License lets you freely modify and distribute
    your software’s code in the source or binary format as
    long as you retain a copy of the copyright notice, list of
    conditions, and the disclaimer.
    20

21. Common Development and Distribution License (CDDL)
    CDDL is an open source license published by Sun
    Microsystems to replace the Sun Public License (SPL).
    You’re free to reproduce and distribute any original or
    derivative works of any software licensed under the CDDL.
    However, you must not remove or make any changes to
    any copyright, patent or trademark notices contained in
    the software. You must also retain any notices of licensing
    or any descriptive text giving attribution to any
    contributor or the initial developer. 21

22. Eclipse Public License (EPL)
    The EPL license is a copyleft license. If you modify an
    EPL’ed component and distribute it in the source code
    form as part of your program, you’re required to
    disclose the modified code under the EPL. If you
    distribute such a program in its object code form,
    you’re required to state that the source code can be
    made available to the recipient upon request. You’re
    also required to share the method for requesting the
    source code.

23. MIT License
    23
    Basically, you can do whatever you want with software
    licensed under the MIT license — as long as you add a
    copy of the original MIT license and copyright notice to
    it. The MIT License is very simple, short and to the point,
    which is why it has such a high adoption rate among
    developers, although some avoid it because it doesn’t
    expressly grant patent rights. Commercial
    organizations often prefer it because of its “no strings
    attached” nature.

    OPEN SOURCE VS. CLOSED SOURCE

    View Slide

28. OPEN SOURCE VS. CLOSED SOURCE
    ▪ Open-source software is based on the idea that the user
    cannot only view but also can change the source code of
    the existing application based on the requirements.
    ▪ Closed-source software contains the source code which
    is hidden to prevent the user either viewing or changing
    the code. It is a kind of proprietary software. (Microsoft
    office, Adobe photoshop). It can be accessed only by
    paying or meeting certain requirements.

35. OPPORTUNITIES
    ▪ It offers practical accessibility to a product's source , so
    that You can know how the program works.
    ▪ This evolves through community cooperation which is
    composed of individual programmers and companies.
    Many of these individuals programmers who start an
    open source project usually end up as large companies
    with open source programs.

36. BENEFITS OF OPEN SOURCE
    Security - the more people who can see and test a set of
    code, the more likely any flaws will be caught and fixed
    quickly.
    Quality - It is more likely to be better quality software
    package as it created by thousands of developers.
    Customizability - business users can take a piece of open
    source software and tweak it to suit their needs. Since the
    code is open, it's simply a matter of modifying it to add the
    functionality they want. 36

44. BEYOND SOFTWARE
    Open source is not only a way to develop and
    license computer software, but also a way means
    expressing a willingness to share, collaborating with
    others in ways that are transparent.
    Its committed to play an active role in improving the
    world.
