5% is opening the software (i.e., sharing software publicly).
95% is opening the source – i.e., opening the developer by getting them to adopt open behavior.
- Willingness to share failures as well as successes
- Adopting (open) community practices of development.
- Getting developers to share code before it's "ready".
- Teaching (pay it forward!), since we're all in this together.
In my experience, developers who can succeed in open source development tend to be better & stronger developers. Similarly, code that is useful to many, by design, needs to be more robust.
My hope is Open Source will promote capacity development & collaboration, empower developers to come up with meaningful and useful solutions to local problems, and promote social equity worldwide.
Open Source will continue to grow and improve as the best practice for software development, Instead of choosing whether source code should be made open source, people will default to open source development and choose to close their source only as exceptions to the new norm.
