Why developing in the open?*

Transparency leads to trust -> anyone can inspect the project

Transparency leads to quality -> developers know anyone can see their work

Transparency leads to feedback -> anyone can study and suggest improvements

Transparency leads to prestige -> good work can be recognized by peers

Open source is taking over the software world, survey says:

Open Web Services and Web Mapping Applications Summer School 2013

... in summary...* 4 freedoms: use, modify, redistribute copies, redistribute changes

* F1 & F3 needs to access the source code

* Is not the same:

-- Free software -- Privative Software-- Open Source Software -- Commercial Software
