# Audience Polls
|
|
||||||
|
|
||||||
+ My goal here is to move faster or slower based on audience knowledge.
|
|
||||||
|
|
||||||
+ There are folks in this audience who have worked with this stuff for years,
|
|
||||||
and those who are completely new.
|
|
||||||
|
|
||||||
+ We want these presentations to be valuable to all of you.
|
|
||||||
|
|
||||||
+ Please, don't be embarrassed:
|
|
||||||
+ Ever GPL expert in the world, including me, started as a student who
|
|
||||||
knew none of this.

# How These Orgs Relate to GPL?
|
|
||||||
|
|
||||||
+ FSF
|
|
||||||
+ Invented copyleft.
|
|
||||||
+ Authors & stewards of the GPL.

# How this Hour Will Go?
|
|
||||||
|
|
||||||
+ Materials presented will mix the simple & complex.
|
|
||||||
|
|
||||||
+ We cannot possibly cover the entire GPL in one hour.
|
|
||||||
|
|
||||||
+ Discuss: motivations, origins, then a few of GPL's sections.
|
|
||||||
|
|
||||||
+ I understand the mix of backgrounds in the audience.
|
|
||||||
|
|

# A Restaurant's Lawyer?
|
|
||||||
|
|
||||||
+ Considering why you want to learn this.
|
|
||||||
|
|
||||||
+ What if your client was a restaurant?
|
|
||||||
|
|
||||||
+ What would you want to need to know?
|
|
||||||
|
|
||||||
# Restaurant Lawyer: What'd You Study?
|
|
||||||
|
|
||||||
+ If you were a restaurant's lawyer:
|
|
||||||
|
|
||||||
+ Probably three areas of law you'd focus on:
|
|
||||||
+ building codes.
|
|
||||||
+ health and safety regulations.
|
|
||||||
+ tax regulations.
|
|
||||||
|
|
||||||
+ Who would want to hear from?
|
|
||||||
|
|
||||||
# Restaurant Lawyer: What'd You Study?
|
|
||||||
|
|
||||||
+ Figure out the motivations behind the building code:
|
|
||||||
+ What parts are arcane and less important to inspectors?
|
|
||||||
+ How do inspections work?
|
|
||||||
+ What are the penalties?
|
|
||||||
|
|
||||||
+ Figure out the same for health & safety:
|
|
||||||
+ Who inspects, and when?
|
|
||||||
+ What's the health code say, and what checklist do inspectors use?
|
|
||||||
|
|
||||||
+ Likely Questions:
|
|
||||||
+ Who's in charge of all this?
|
|
||||||
+ What's purpose and intent of these regulations?
|
|
||||||
+ Can I meet the inspectors?
|
|
||||||
|
|
||||||
# Why Listen To Us?
|
|
||||||
|
|
||||||
+ FSF: Understanding the purpose and intent of the GPL.
|
|
||||||
|
|
||||||
+ Conservancy & FSF:
|
|
||||||
+ both enforce the GPL.
|
|
||||||
+ if your client violates, you will hear from one of us.
|
|
||||||
|
|
||||||
+ Such access to drafters, interpreters, enforcers is highly unique.
|
|
||||||
|
|
||||||
+ Someday, we may (or already have) sit across the table from you.
|
|
||||||
|
|
||||||
+ Our transparency does make your job easier.
|
|
||||||
|
|
||||||
# The Mindset of GPL
|
|
||||||
|
|
||||||
+ GPL protects software freedom.
|
|
||||||
|
|
||||||
+ Ultimate goal: make sure every user has the four freedoms.
|
|
||||||
+ Freedom to run the software.
|
|
||||||
+ Freedom to study and modify the software.
|
|
||||||
+ Freedom to share the software.
|
|
||||||
+ Freedom to distribute modified versions.
|
|
||||||
|
|
||||||
+ Every clause in GPL was designed to uphold one of these freedoms.
|
|
||||||
+ Or, it's a compromise of drafting in adoption vs. freedom debate.
|
|
||||||
|
|
||||||
# Using Copyright
|
|
||||||
|
|
||||||
+ GPL is primarily a copyright license.
|
|
||||||
+ Software is copyrighted.
|
|
||||||
+ License grants key freedoms.
|
|
||||||
+ Requirement prohibit activities that take away freedoms.
|
|
||||||
|
|
||||||
+ General concept: copyleft.
|
|
||||||
|
|
||||||
+ Specific implementation: GPL.

# Compare To Proprietary Licenses
|
|
||||||
|
|
||||||
+ Yes, the GPL has its requirements.
|
|
||||||
|
|
||||||
+ But *none* of these activities are ever permitted under proprietary
|
|
||||||
licenses.
|
|
||||||
|
|
||||||
+ If you don't like what the GPL requires you to do, then just tell your
|
|
||||||
client to use the proprietary software instead.
|
|
||||||
|
|
||||||
+ That way, they know the answer to every question is “no”
|
|
||||||
|
|
||||||
+ rather than: “yes, but only as long as you …”
|
|
||||||
|
|
||||||
# The Technical Gap
|
|
||||||
|
|
||||||
+ Understanding GPL well requires a some software expertise & legal
|
|
||||||
expertise.
|
|
||||||
|
|
||||||
+ You don't have to be a professional on either side to grok it.
|
|
||||||
+ but you're best off if you're a professional in one & an amateur
|
|
||||||
in the other.
|
|
||||||
|
|
||||||
+ Most important technical concepts you need:
|
|
||||||
+ source code, binaries, methods of distribution.

# The GPL is a Complex Topic
|
|
||||||
|
|
||||||
+ An in-depth seminar on GPL's provisions is a one-day course …
|
|
||||||
+ … but the written materials discuss every section in depth.
|
|
||||||
|
|
||||||
+ Keep in mind: every requirement has a carefully considered purpose to
|
|
||||||
uphold freedom of users.
|
|
||||||
|
|
||||||
+ Software freedom licenses have a moral perspective.
|
|
||||||
+ This is probably the most difficult thing for lawyers to understand.
