A recent article by Darrel C. Ince, Leslie Hatton, and John Graham-Cumming.
Scientific communication relies on evidence that cannot be entirely included in publications, but the rise of computational science has added a new layer of inaccessibility. Although it is now accepted that data should be made available on request, the current regulations regarding the availability of software are inconsistent. We argue that, with some exceptions, anything less than the release of source programs is intolerable for results that depend on computation. The vagaries of hardware, software and natural language will always ensure that exact reproducibility remains uncertain, but withholding code increases the chances that efforts to reproduce results will fail.

Les Hatton was in computational geophysics research for 15 years. He is the primary author of a great introductory book “Seismic Data Processing: theory and practice”. He switched careers after that to study software and systems failure.
