1. Open design at large scale

2. The real value of Docker is not technology
It’s getting people to agree on something

3. How active is
Docker?

4. 4854 PRs (Oct 2014, sub-projects not included)

• Differences are noticeable but reasonable: initial maintainers are by definition
employees. “community” includes the long tail of low-quality patch bombs.

Please give feedback!

12. Human organizations
are programmable.
Bugs can be fixed, scale bottlenecks
removed, inefficient code refactored

13. We can define a new
model for open-source
at large scale
