DPS909 & OSD600 Winter 2018
Week 1
- Some questions:
- When you hear "open source," what comes to mind?
- On a scale from 1 (not at all) to 5 (very)...
- How comfortable are you working with technology you've never seen before?
- How curious are you about how things work?
- How likely are you to stick with a problem when it gets hard to solve?
- How likely are you to ask for help when you get stuck?
- How likely are you to pause your own work in order to help someone else who is stuck?
- How self-motivated are you?
- How self-directed are you?
- How to have Success in this course:
- Willingness to be lost and not panic
- Willingness to put yourself out there, jump in
- Curiosity
- Being driven, persistence
- Willingness to ask for help
- Willingness to give others help
- Independent learning
- Doing more than the bare minimum
- Discussion
- 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 (Copyright in Canada video)
- 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
- 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)
Week 2
- 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
- No License
- What can you do with code you find that has no license?
- what can I, can't I do?
- Public Domain
- SQLite, which is now used by literally everybody, see http://www.sqlite.org/famous.html
- Unlicense
- Consider some proprietary/closed End User License Agreements (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:
- 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 can modify it freely
Week 3
- TODO:
- Finish Lab 1
- Complete Release 0.1 Part A
- Start Learning Git, GitHub
- Source Code Reading: by reading code we didn't write, we often learn things we didn't know were possible.
- Consider libphonenumber's
Leniencytype and Constant-Specific Methods in Java. ENUMs can define an abstract method and override them with a concrete method in each constant - Consider
\p{...}Unicode categories in Regex- https://mothereff.in/regexpu
