Opensource

  1. 1. What is Open Source? open source can be thought of as philosophy which gives then user the freedom to download, run, copy, distribute, share and change the software for any purpose they desire, without paying licensing fees and discrimination. It runs on the methodology that users should not be limited in ways they could use their software but should be encourages to increase its productivity or understand how their software works as well as appreciate it's beauty and working. ➢ open as in free ➢ open as in access ➢ open as in not closed ➢ open as in reuse and change ➢ open as in any place and for anyone “Free as in Freedom not as in Free beer”
  2. 2. Free Software Foundation The main force behind the open source initiative is the Free Software Foundation. It says that users enjoy four types of freedom ➔ Freedom to run the program for any purpose ➔ The freedom to study how the program works, and change it so it does your computing as you wish. Access to the source code is precondition for this. ➔ The freedom to distribute the copies of your modified versions to other. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is precondition for this. ➔ The freedom to to distribute the copies to anyone you want.
  3. 3. Open Source Model
  4. 4. Working of Open Source
  5. 5. Advantages of Source Code  Availability of source code v Source code to understand and learn from v Do not have to re-invent the wheel v Free as in “freedom”  Does not depend on vendor v Can choose additional support v Can fix bugs and adapt to change in requirements as well as technology  Quality and Customizability in open source is better.  Costs much less than proprietary counterparts.
  6. 6. Disadvantages Of Open Source  Not generally straightforward to use and requires a certain learning curve to use and get accustomed.  Incompatibility issue with software and hardware. (3rd party drivers)  Bad Codes, and some unqualified people who uses it.  Software quality assurance process is widely not transparent  No financial incentive.
  7. 7. Open vs Closed Source
  8. 8. Case Studies
  9. 9. inland and Sweden collaborate Sweden and Finland exhibit in this case study exemplary cross-border collaboration based on open source software for the benefit of the public. Two universities, one from each country, cooperated in the Open Kvarken project in order to explore the use of OSS by public administrations. The name of the project is symbolic, as Kvarken is the name of the Archipelago that separates (or unites) the two neighbors The project in three years has shown interesting examples of OSS use in the public sector and the operation of two centres of open source knowledge, in Vaasa, Finland and Umeå, Sweden.
  10. 10. The Swedish National Police In 2006 the Swedish National Police launched a project that led to the implementation and migration from an ICT infrastructure based on proprietary products to an ICT server and database platform based on Open Source software and open standards. The previous ICT platform was very costly and obliged the Police to stick with a hand full of vendors. The aim was therefore to cut costs, avoid vendor lock-in, achieve better performance, and introduce open standards. Before ideas were realized, a thorough study was conducted to calculate costs and benefits. This study foresaw cost savings of up to fifty percent over a five years period compared to the proprietary hardware and software in place at this time, while improving performance at the same time. Due to the dimensions of this project that affected the entire ICT infrastructure of the Swedish National Police, it was not always easy to turn ideas into reality.
  11. 11. The Open University UK In 2005 The Open University (OU) UK, one of Europe's largest distance learning universities, established that it was time to deploy a new Virtual Learning Environment (VLE), for both The Open University itself as well as for their OpenLearn project aimed at providing free open educational resources (OER) to the general public. A team with different sub-tasks was formed, which investigated future learning environments and how learning material was presented and disseminated through those. Next to this, the OU also researched open learning models, as part of the OpenLearn project. The team of researchers and technical staff, after setting out the components required to meet the OU's needs the most appropriate match was determined. The choice fell on the VLE Moodle, which is an open source product. Today the Moodle VLE has been successfully implemented at the OU and the OU has further published a significant amount of their learning material under a Creative Commons license as courses on the Moodle VLE based OpenLearn website, which are freely available to anyone interested. The OU continues to collaborate closely with the Moodle community, as this provides a very large platform for feedback and information. All the OU's development is given back to the Moodle community, which improves the product for the OU and the rest of the community.
  12. 12. AirAware In 2005 the Romanian National Meteorological Administration (NMA) received EU funding for its AirAware project. The project's objective was to improve the air quality monitoring system currently in place and to enhance the system with forecasting capabilities. For the management of all the information and the presentation thereof, the team at the NMA developed a portal that is entirely built on Free/Libre Open Source Software. In the future, the team is hoping to open the project to the public.

  14. 14. Examples
  15. 15. Linux OS Linux OS the world's most free open operating system is considered to be one of the most important step in the open source initiative. With millions of users, this operating system is growing day by day..This flexible system has proved to supersede the windows system in every case and is used not only in daily life but to protect sensitive data in most important country agencies. With it not being vulnerable to virus, large support community and flexibility as opposed to windows, it is considered to be the best operating system by industry experts.
  16. 16. Android Android, now is one of the most used mobile operating system. Before it's adoption, apple's IOS used to rule the market, but since it's release and adoption, IOS has since lost it's market and android has risen to the top. Android is based on the very famous linux operating system and offers the same flexibility that the linux offers in it's desktop. Behind android is a community having more than million members developing and improving it, which is not possible in any closed mobile operating system
  17. 17. When talking about open source how can we forget about our very own open source Content Management System called Wordpress. This awesome solution is reported to power more than 50% of the world's website's. Which is far more than it's closed source competitor’s. This solution offers flexibility to websites as well as a method to make professional website with just a single click. It was originally intended as an easy way to set up a blog. But, thanks to the efforts of a large “open source” community of WordPress programmers working to extend and improve its capabilities, WordPress has now became an essential tool for a web developer
  18. 18. Conclusion
  19. 19. We are in the Open Source Revolution where people collaborate to create, produce software or technology. Based upon the key advantages of Open source technology , we can finally conclude that open source deserves the increasing “Given enough eyeballs, all bugs are shallow.” -Linus Torvalds
  20. 20. All in all, Open Source is the future and will be the key to unlock the next generation in technology . I mean even the Simpson's recommend it :P
