  1. Why Open Source? Karl Fogel kfogel@opentechstrategies.com

  2. What is Open Source? Karl Fogel kfogel@opentechstrategies.com

  3. Open source software is software that may be modified and redistributed freely by anyone, with no restrictions on how the code may be changed, the uses to which it may be put, or the parties with whom it may be shared.

  4. What does “open source” make you think?

  5. Open source software is commercial (COTS)

  6. Open source software is commercial (COTS)

  7. Open source software is commercial (COTS) • It's just not proprietary

  8. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS

  9. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS

  10. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS • “Open source” same as “free software”

  11. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS • “Open source” same as “free software” • Copyleft vs non-copyleft (both qualify)

  12. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS • “Open source” same as “free software” • Copyleft vs non-copyleft (both qualify) • Lots of religious wars in open source

  13. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS • “Open source” same as “free software” • Copyleft vs non-copyleft (both qualify) • Lots of religious wars in open source • But not about the definition

  14. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS • “Open source” same as “free software” • Copyleft vs non-copyleft (both qualify) • Lots of religious wars in open source • But not about the definition • You open source your code, not your time

  15. Open source software is commercial (COTS) • It's just not proprietary • No such thing as academic-only OSS • No such thing as non-profit-only OSS • “Open source” same as “free software” • Copyleft vs non-copyleft (both qualify) • Lots of religious wars in open source • But not about the definition • You open source your code, not your time • You control your copies
