I recently asked how to express dictionaries in pseudocode in the question Dictionaries in pseudocode and was in doubt whether it belongs here (and so were others). I thought it's not about actual programming (which would bring it to Stack Overflow) but only about how to present it, which is certainly related to computational science.
I think Computational Science needs a more detailed description of what's on-topic here (the FAQ mainly talks about what is not) and also a better differentiation to Stack Overflow. From what I see, most questions asked here could have also been asked identically on Stack Overflow.
