What is open source?




Simple: you can read the code.
You can see how it’s made.
Two main characteristics....first, it’s free as in beer
Second (much more important and interesting), it’s free as in freedom.

Introduction To Open Source

  1. 1. What is open source? Simple: you can read the code. You can see how it’s made.
  2. 2. Two main characteristics....first, it’s free as in beer
  3. 3. Second (much more important and interesting), it’s free as in freedom.
  4. 4. Richard M.Stallman Richard M.Stallman is the founder of the free software movement Four basic freedoms
  5. 5. Four freedoms • The freedom to run the program for any purpose • The freedom to study how the program works, and adapt it to your needs • The freedom to redistribute copies • The freedom to improve the program
  6. 6. Why is this cool?
  7. 7. Potential. One of these is full of potential One of these is sterile
  8. 8. Anyone can do whatever they like with it. NEA: Nobody owns it, Everyone can use it, Anyone can improve it
  9. 9. Improved in terms of quality “With enough eyeballs, all bugs are shallow”
  10. 10. Improved in terms of quantity of code (functionality) People add layers on top of other people’s code
  11. 11. As the code base grows, the potential grows Improves chances of it being used for something not intended by the originator
  12. 12. All fine in theory, what about in practice Reputation for being ugly...maybe beautiful on the inside
  13. 13. Lots of companies quietly making a fortune Valued at $23 billion
  14. 14. Firefox, Thunderbird, smaller ones such as Fennec $60m a year
  15. 15. Shock, horror! FreeBSD 5. Bundles over a hundred of the most popular Open Source products. Safari. Based on Webkit. Open source.
  16. 16. BT make money from their hardware, which uses Linux.
  17. 17. A cool, calm, totally unbiased comparison of the merits of both open source and proprietary software Open source Proprietary Cost of licence £0.00 $$$! Cost of upgrade £0.00 $$$! Cost of change £0.00 / Time $$$ / Time / Impossible Ability to reconfigure Unlimited Variable Ability to innovate High Low Ability to extend High Low Ability to develop Varied Varied Look and Feel Poor Poor Why? Let’s look at benefits. NOT from agency view, but from business owners view. Ability to innovate - your business may depend on this. Software companies daren’t read feedback from customers Look and Feel - our Open Source Show And Tell event shows us they are investing in this.
  18. 18. Vendors ask customers what they want Ford: If I’d asked customers what they wanted, they would’ve asked for faster horses Open source is the demand side supplying itself
  19. 19. Two types of licence: Permissive Copyleft Permissive licences = you can do whatever you want (example: BSD) Copyleft = Opposite of copyright, rather than adding restrictions you’re removing them (example: GPL). “Join the Family”. Derived works must keep this licence. Freedoms are preserved. IF you distribute improvements, you must re-publish on these terms.
  20. 20. Community is as important as the code Building, Supporting Hiring
  21. 21. Motivations Credibility in peer group, altruism, real passion for the product, fun, creativity ....and maybe even money
  22. 22. “First they ignore you, then they laugh at you, then they fight you, then you win.” Evolution of open source: First they ignore you, then they laugh at you, then they fight you, then you win. Proprietary vendors have fought against open source (SCO case), now claiming their products work well with open source.
  23. 23. 9 Examples (many of these are arguably best of breed, and improving all the time): Firefox - 200 million users 2003: Internet Explorer had ~99% of the browser market Q4 2008 Browser Share; Internet Explorer 68.12%, Firefox 21.34%, Safari 7.93%
  24. 24. Webkit - Safari and Google Chrome
  25. 25. Drupal - Version 7 being released early next year
  26. 26. Wordpress has been downloaded 4,636,629 times Well over 4 million blogs on Wordpress.com too
