Why Open Source Software/Open Hardware?

  1. 1. Why Open SourceSoftware/Open Hardware?Lenandlar SinghLecturer, Department of ComputerScience, University of GuyanaHardware Freedom Day 2013, Guyana
  2. 2. OUTLINE Openness FOSS/OSHW Opportunities and Challenges OSHW Projects Future
  3. 3. Openness FOSS – Free and Open SourceSoftware OERs – Open Educational Resources MOOCs – Massive Open OnlineCourses Open Data, Open Government Open Hardware Open Everything… Why?
  4. 4. FOSS/OSHWOpen hardware is like open softwareusers :are allowed to use, to improveand to redistribute existingprojects freely.designers :publish documents, software,..essential to design the device.but is it really…
  5. 5. Open Source Hardware (OSHW)Graham Seaman suggests that truly open hardware wouldhave to satisfy the following requirements: The interface to the hardware must be explicitly madepublic, so the hardware can be used freely. The design of the hardware must be made public, so thatothers can implement it and learn from it. The tools used to create the design should be free, so thatothers can develop and improve the design.http://conviviality.ouvaton.org/article.php3?id_article=44
  6. 6. FOSS/OSHW – Things to think about Sharing – share as many copies of the FOSS (end product),can’t do with hardware (1 copy is 1 copy) – real products,not code  Design – OSHW design available, product can be built fromit, FOSS product available but have to figure out design? COST – entry to FOSS is probably cheaper /easier thanOSHW FOSS – Copyright Law/ OSHW – Patent Law --- See TAPRhttp://en.wikipedia.org/wiki/TAPR_Open_Hardware_License Not all OSH might be of interest to the Computing Industry
  7. 7. FOSS/OSHW –Things to think about
  8. 8. LicensesLicenses Share-Alike style CERN Open Hardware License – CERN developedOSHW license inspired by the GPL TAPR Open Hardware License – TAPR developedOSHW license inspired by the GPL Attribution Only style Mach 30 Open Design Pledge – Mach 30 developedlicensing bundle for OSHW Solderpad Hardware License - Modified ApacheSoftware License for use with hardware projectshttp://mach30.org/open-source-hardware/
  9. 9. A Criticism of the TAPR the license has "lots of problems" and that it"strips the word distribution of its normalmeaning, assuring lots of contention over edgecases.“ – Eric Raymond ”also concerns that the Open Hardware Licensemay merely place the design and/or idea intothe Public Domain by effectively publishing itbefore securing the benefits of patent protection” ---http://en.wikipedia.org/wiki/TAPR_Open_Hardware_License
  10. 10. Advantages for Developing Countries Knowledge Transfer Cost Reduction of Design Process Explore and encourage innovators Wide Range of users – end users,marketer, developers etc
  11. 11. Potential Problems Lack of Technical Expertise Low levels of industrial R&D Supply/Demand? Waste Cooperation between Industry andUniversity?

  13. 13. Close hardware and wasteClose hardware is a waste of money and asource of pollution.Repairing computers costs money. E-waste, Ghana.

  15. 15. ConclusionOpen hardware is about…… open design,…telling people how devices are made,…improving devices,…reducing costs
  16. 16. So What Next? What can we do? Projects to play around with? Should we care? What is in it for us?
