If the same results are obtained using different code (or subjects/animals/chemical batches) does it matter as long as the code is doing the same things? I get the impression that software types are inclined to put way too much significance on the source code. I'm not surprised the author of the linked item in Nature is a software engineer. I wonder, did scientists in the 1930s publish their scratchpads full of calculations?
