"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."
