The Guardian is running this piece "If you're going to do good science, release the computer code too", about the need to have open source program code from scientific studies. And Slashdot picked up on it too: Call For Scientific Research Code To Be Released.
It's good to see this view being recognized. I have, of course, expressed similar ideas before as in Credibility of Science and Open Source Methodology. Beyond open sourcing the methods, I also recommended the opening of the data sources as in Credibility of Science and the Freedom of Data, as a response to the recent Tarnishing of Science's respectability from the Climategate incident.
We need to recognize that this will continue to be a recurring issue in science as computing technology continues to revolutionize how all science is done.
