  • Why Reproducible?
    • Science is the systematic enterprise of gathering knowledge about the universe and organizing and condensing that knowledge into testable laws and theories. The success and credibility of science are anchored in the willingness of scientists to independent testing and replication by other scientists. This requires the complete and
    • open exchange of data,
    • procedures and materials .
  • Open-Source Software
    • “ Abandoning the habit of secrecy in favor of process transparency and peer review was the crucial step by which alchemy became chemistry. In the same way, it is beginning to appear that open-source development may signal
    • the long-awaited maturation of
    • software development as a
    • discipline.” Eric S. Raymond
  • How to Do Reproducible Computational Experiments?
    • Code attached to published results
    • Continuous maintenance
    • Previous results used for testing
      • Test-driven development
    • Lessons from open-source
      • Intellectual property
