  1. 1. “FOSS”?- Getting Results with Open Source SolutionsOPENING MIND WITH OPEN SOURCE
  2. 2. Philosophy of “Free” or Open Source Software“Free software” is a matter of liberty, not price. Tounderstand the concept, you should think of “free” asin “free speech,” not as in “free beer.”—Richard Stallman, Founder of the Free Software Movement
  3. 3. Philosophy of “Free” or Open Source SoftwareThe Open Source Licensing Model ( four essential freedoms:• The freedom to run the program, for any purpose(freedom 0).• The freedom to study how the program works, andchange it to make it do what you wish (freedom 1).Access to the source code is a precondition for this.• The freedom to redistribute copies so you can help yourneighbor (freedom 2).• The freedom to distribute copies of your modifiedversions to others (freedom 3). By doing this you cangive the whole community a chance to benefit from yourchanges. Access to the source code is a precondition forthis.
  4. 4. Values of Open Source- Freedom- Transparency- Extensibility- Collaboration- InnovationStrength in numbers!
  5. 5. Successes of Open SourceOperating Systems: Linux, Symbian, GNU Project,NetBSD.Servers: Apache, Tomcat, MediaWiki, Drupal,WordPress, Eclipse, Moodle, JoomlaProgramming Languages: Java, JavaScript, PHP,Python, RubyClient software: Mozilla Firefox, Mozilla Thunderbird,OpenOffice, Songbird, Audacity, 7-ZipDigital Content: Wikipedia, Wiktionary, ProjectGutenberg
  6. 6. FOSSFOSS is increasingly the go-to standard for operatingsystems to user applications, for individuals to largeenterprises. It helps reduce costs, avoid lock-in,increase productivity, enhance security, and improvestandards compliance.
  7. 7. TODAYS FOSS IN ORGANIZATIONS?Free Open Source Software can be supported by anyonethat wishes to do so. It is generally developed by meritocraticteams of developers, associations of companies, businessesthat provide support and services, non-profit foundations, andresearch and academic institutions.Key organizations in the Free Open Source SoftwareincludeFLOSS Manuals -- FLOSS Manuals is a community creatingfree manuals for free and open source software.FOSS Learning Centre -- An international non-profitorganization serving as an information and training hub forconferences, webcasts, online videos, and workshopsproviding information about with free open source software.
  8. 8. Contd..GOSLING - "Getting Open Source Logic INto Governments", isan informal learning and knowledge-sharing community.Open Source for America -- A cross-section of technologyindustry leaders, associations, non-governmental organizations,communities, and academic/research institutions.Open Source Initiative -- The original popularizer of the term"open source", and the recognized certification authority forwhether or not a given software license is Free Open SourceSoftware.Open Source Software Institute -- Non-profit organization ofcorporate, government and academic representatives topromote open-source solutions.
  9. 9. Primary Sources….Apache Software Foundation- Offers an array of Free OpenSource Software web development services, including Javaapplications servers, frameworks, and application developmenttools.GitHub- Provides access through the GIT configurationmanagement – Best known for the Firefox web browser.Savannah - Central point for development, distribution, andmaintenance of GNU – Supports tens of thousands of open sourceprojects, including community organization and management toolsto help teams develop their software.
