Week 2

• Let's talk about Copyright and Open Source Licenses
  • • IANAL: "I Am Not A Lawyer"
    • We're going to explore licensing from the POV of a developer participating in open projects

• Copyright
  • Who created it, "owns" it.
  • Set of exclusive rights granted to the work's creator
  • "The right to copy," to produce or reproduce a work or substantial portion thereof
  • Copyright is automatic when a work is created, you don't have to register it.
  • Copyright in Canada
  • Copyright Guide
  • Copyright lasts the life of the author + 50 years
  • In a software project, there can be many copyright holders (e.g., many contributors), or all contributors may assign their copyright to the project (e.g., CLA, which we'll cover later)

• Licenses
  • Rights, privileges, responsibilities, etc. applicable to someone other than the work's creator
  • "Terms and Conditions"
  • These must be granted by a copyright holder

• Public Domain
  • SQLite, which is now used by literally everybody, see http://www.sqlite.org/famous.html
  • Unlicense

• No License
  • What can you do with code you find that has no license?
  • what can I, can't I do?

• Consider some proprietary/closed End User License Agreements (EULA)
  • Richard Dreyfuss reads the iTunes EULA
    • Part 1: Please Read (.mp3)
    • Part 2: Responsibility (.mp3)
    • Part 3: Damages (.mp3)
    • Part 4: Effective Until (.mp3)
  • Spotify EULA

• Open Source Licenses
  • The Open Source Definition
  • Approved licenses by the Open Source Initiative: https://opensource.org/licenses
  • Choose a License: https://choosealicense.com/

• Learning Licenses: BSD
  • Family of Licenses, including 2-Clause BSD, 3-Clause BSD (aka New BDS), 4-Clause BSD
  • "Why you should use a BSD style license for your Open Source Project"
  • BSD Licenses code is usually compatible with other open/closed code, when you want to mix them.
  • Example software projects licensed under the BSD License:
    • Many Google Projects, including V8, Chromium, Go
    • D3.js
    • Django
    • nginx
    • Vi
    • Facebook uses a modified version of the 3-Clause BSD they call [BSD + Patents license]. This has been controversial
      • BSD + Patent
      • PATENTS in React
      • https://code.facebook.com/posts/112130496157735/explaining-react-s-license/
  • Summary:
    • You need to retain the license and copyright notice
    • You can use it commercially or non-commercially (privately)
    • You can distribute it freely
    • You an modify it freely

• Lab 2 - will be done online, and will involve compiling Firefox from source. Details will be posted later this week.
