Transcript

  • 1. Refresher Course at CSD Mumbai University. Jan-14 2013 Presenter: Amol A Sale amol@joyoflinux.com Open Source for academics.
  • 2. Outline  What is Open Source?  Who runs open source projects?  Why open source?  Business models  Contributing to open source.  Why to contribute?  What benefit student or professional gets out of it?  Adopting Open Source in academics.  Resources
  • 3. What is Open Source?  “The practice of providing open-source code for a product; Open-source software in general; To make open-source”  Free sharing of technological information like cooking recipes have been shared since the beginning of human culture. Sharing cooking recipe does not mean sharing cooked food.
  • 4. Why open source?  FLOSS potentially saves industry over 36% in software R&D investment that can result in increased profits or be more usefully spent in further innovation.  No code is good code, there is always scope for improvement and human limit may restrict the growth of your project, so open the source.  To make your code world class.  Open source software projects may offer a learning opportunity those students aren't getting in school.  The best run open source projects have real standards, and teams of experienced programmers.
  • 5. WHO IS DOING IT?
  • 6. Source: Linux Kernel Development How Fast it is Going, Who is Doing It, What They are Doing, and Who is Sponsoring It A White Paper By The Linux Foundation http://www.linuxfoundation.org/
  • 7. Source: Linux Kernel Development How Fast it is Going, Who is Doing It, What They are Doing, and Who is Sponsoring It A White Paper By The Linux Foundation http://www.linuxfoundation.org/
  • 8. Why they contribute?  Companies like IBM, Intel, SGI, MIPS, Freescale, HP, etc. -- to ensure that Linux runs well on their hardware.  Distributors like Red Hat, Novell, and CentOS, Ubuntu have a clear interest in making Linux as capable as it can be.  Companies like Sony, Nokia, and Samsung ship Linux as a component of products like video cameras, television sets, and mobile telephones.  VMWare - built on Linux kernel.  Nvidia – Interested in Graphics business.  Intel – Processor family interest  Google – Run many Linux based servers in house.  Volkswagen?
  • 9. Why do people contribute? “Human beings have an inherent tendency to seek out novelty and challenges, to extend and exercise their capacities, to explore, and to learn.” Daniel H. Pink (Author of DRiVE - What motivates us?)
  • 10. Why students/we should contribute to Open Source? You get :  Good developers have always known that the way to improve is by reading well-written programs. Good FOSS projects in dynamic communities provide a wealth of examples for students to read, understand, and work on.  Chance to interact with world class software team.  Chance to read, modify or improve world class source code.  Learn from constructive feedback of mature, well-run FOSS project team  Learn project management.  Essential professional software development skills that are seldom well- taught in formal school settings.  Learning Communications and social skills.  Participation in FOSS projects can generate a very public portfolio of practical work. This beats a resume any day. It also makes it easier to show your previous work to a potential employer.
  • 11. Business models  Open source software can be sold and used commercially.  Donations?  Saas? Iaas?  Though there are FOSS apps around developed by big companies, Open source does not always means free of cost.  You can charge/sell your software along with source code.  You can distribute it free and charge for Support.  Important: First understand the Licensing in depth and then go with business.
  • 12. Examples  Canonical Ltd. offers Ubuntu for free, while they sell commercial technical support contracts.  Mozilla Foundation have a partnership with Google and other companies which provides revenue for inclusion of search engines in Mozilla Firefox.  MySQL is offered for free, but with the enterprise version includes support and additional features.  Novell offers openSUSE for free through the openSUSE Project, while selling SUSE Linux Enterprise (SLE).  Red Hat offers the Fedora for free through the Fedora Project, while selling Red Hat Enterprise Linux (RHEL).  Oracle offers OpenOffice.org for free, while selling StarOffice.
  • 13. So do you ...  use good quality FOSS every day?  like the freedom and openness of the Internet?  think that Internet content should remain free?  share stuff with your friends for free? BUT  Did you know that all (a lot) of this stuff is based on... FOSS ?
  • 14. You use Open Source Software every day.  When you e-mail a document, pay your taxes online, book an airline flight or do a search for a long lost relative, you’ve just used open-source software.  Every startup has access to the same technology that only large enterprises could afford in the past.
  • 15. Business Models using Open Source?  Come up with a distinctive practical idea.  See if there is any work done towards it in open source projects.  If yes, See how can you adopt it and make it compatible with your idea?  If not, start a new open source project  Every tool is available there starting from kernel, filesystem to web server, open source social network platform find ways to adopt it to your idea.  CMS (Content Management Systems) – Drupal, Wordpress, Open Cart, MediaWiki and many more.  Open Source consultancy to SMEs or individuals.  Open source training.  Hosted Services – Cloud, Virtualization based infrastructure.  Saas or Iaas
  • 16. HOW OPEN SOURCE CAN PLAY BIG ROLE IN ACADEMICS?
  • 17. Open educational resources
  • 18. So how to get started?  OSS Watch is an advisory committee which provides comprehensive analyses of the legal, technical, and economic aspects of open source software implementation in the higher education sector.  http://www.oss-watch.ac.uk/  Open educational resources are online resources that provide free applications and learning materials for academic institutions. includes complete course materials, modules, journals, reference materials. These resources can be modified and redistributed.  http://www.oercommons.org/
  • 19. Open source curriculum (OSC)
  • 20.
