Our philosophy about sharing code

Scientific codes are tools—or you can view them as protocols to use a tool: the computer. When we share our tools and protocols for making science, and others use them for their discoveries, it multiplies our impact in science. This is one, rather philosophical, reason for sharing our codes.

A more practical reason for publishing our codes is reproducibility. It is a long tradition of science that experiments are to be reported so that others can repeat them. In experimental work, this often means a thorough description of materials, methods, and protocols.

So that others can repeat our results, we reveal our “methods”—the mathematical models, algorithms, and implementation in a programming language.
