Reproducible Research, a manifest-like paper by a number of authors from different scientific disciplines, is published by Computing in Science and Engineering.
Progress in computational science is often hampered by researchers' inability to independently reproduce or verify published results. Attendees at a roundtable at Yale Law School formulated a set of steps that scientists, funding agencies, and journals might take to improve the situation. We describe those steps here, along with a proposal for best practices using currently available options and some long-term goals for the development of new tools and standards.

Seismic Unix (SU) is a famous open-source seismic processing package maintained by John Stockwell at the Center for Wave Phenomena, Colorado School of Mines. SU has been around for 25 years and has attracted many devoted users. If you are one of them, please consider the following:

Eureka Daily, a science blog at The Times newspaper, published a two-part article by Hannah Devlin about freedom of information in science ("FOI: should scientists be exempt?" and "Freedom of information and climate science" - both require a subscription). Part two discusses issues of openness in the context of a recent investigation of research practices of CRU - a climate research group at The University of East Anglia.
Here is an interesting excerpt from the second part:
John Graham-Cumming demonstrated why reproducibility is crucial for computational sciences: it exposes scientific algorithms and workflows to a greater audience, thus preventing critical bugs from going unnoticed.
Reproducibility is an approach to openness in computational sciences. It assumes that not only data but source code (and eveything else needed to reproduce published results) should be released. At the end of the day, it might save one's scientific credibility from a rather unpleasant public exposé.

The July 2010 School and Workshop in Houston went well and attracted more than 50 people, about half of them being graduate students. About 10 companies and 12 universities were represented. The event was sponsored by the Petroleum Technology Transfer Council. All presentation materials from the workshop are now available on the website.
