Word of Caution

What's Free Software?

The users have the freedom to run,copy,distribute,study,change and improve the software.

  • Software that respects user's freedom and community
  • Matter Of Liberty Not Price, which everyone deserves

Software Freedoms

  • Freedom 1: Access the source code, study how program works and change it

Software Freedoms

  • Freedom 2: Redistribute copies so you can help your neighbour
  • Freedom 3: Distribute copies of the modified versions

Free Software != Freeware

What's Open Source?

  • Developed as public collaboration and made publicly available
  • Technically Superior than Proprietary Softwares
