[open-science] citing a code and data on a GitHub repository

[Piotr Migdal]

Hi!

Does any of you know what is the preferred way to cite code (placed on GitHub)? 

I saw the question here:
http://academia.stackexchange.com/questions/14010/how-do-you-cite-a-github-repository

Also, a similar question (i.e. citing things not being journal publications) for  OEIS: 
http://mathoverflow.net/questions/131245/how-to-cite-a-sequence-from-the-on-line-encyclopedia-of-integer-sequences-oeis

Do you know what is "good practice"?
Is there some (perhaps informal) place trying to standardize the format (e.g. in BibTeX) or in general worth looking for a reference? 

Regards,
Piotr
