8. Reproducible Research “It is a big chore for one researcher to reproduce the analysis and computational results of another […] I discovered that this problem has a simple technological solution: illustrations (figures) in a technical document are made by programs and command scripts that along with required data should be linked to the document itself […] This is hardly any extra work for the author, but it makes the document much more valuable to readers who possess the document in electronic form because they are able to track down the computations that lead to the illustrations.” (Claerbout, 1991)

15. Madagascar Project What is the purpose? What is in the package? What makes it open-source? – License – Governance – Community

16. Free Software (GPL) Run the program as you wish, for any purpose. Study how the program works, and change it so it does your computing as you wish. Redistribute copies so you can help your neighbor. Distribute copies of your modified versions to others so you can help your community.

18. Open-Source Governence The governance model used by an open source project encapsulates all the hard questions about a project. Who decides on the project roadmap? How transparent are the decision-making processes? Can anyone follow the discussions and meetings taking place in the community? (Laffan, 2012)
