Understanding Open Source Technologies and Their Benefits in Software Development

This document explores the fundamentals of open source technologies, emphasizing their distinction from closed source software. It discusses various licensing types, notably the Berkeley Software Distribution (BSD) and the GNU General Public License (GPL), which govern the use of open source software. The insights into community involvement highlight the significance of collaborative coding efforts and successful project development. Additionally, future developments in assistive technologies and tools are outlined, showcasing the potential for growth and innovation within open source frameworks.

  2. Overview • Open Source Software • Licences • Community • Code • Benefits • Future development What Is The Difference Between Open Source And Closed Source Software? http://www.thegeminigeek.com/what-is-the-difference-between-open-source-and-closed-source-software/

  3. Open Source Software • Distributed with source code – dependent on certain licences • Not the same as freeware or public domain • www.opensource.org

  4. Licences • Around 58 possible licences – take care when you make your choice! • ATbar is being released under Berkeley Software Distribution (BSD) – this is the most open licence • Most popular - GNU General Public Licence 2.0 (GPL) - all derivative works must come under this licence. (http://osrc.blackducksoftware.com/data/licenses/)

  5. Community

  6. Why Community Code Community Factor of Success Time farra@apache.org

  7. Code • Often a main developer and small contributions from others • Make it possible to add small amounts of code to help a project e.g. Atbar plugins • Need to have agreement about the code that will be accepted • Open, online communication

  8. Benefits • Encourages collaborative working • Good publicity • Makes you write good code! • Problems shared – bug tracking, issues raised, comments made, new ideas. • Future developments

  9. Access Tools pendrive • Distributed on USB flash drives and as downloads. • Useful open source and freeware tools which require permission to redistribute. • Developers of AT have generally been willing to allow distribution.

  10. ATkit – the Framework https://github.com/AccessAtECS/AtKit

  11. Future Developments
