Huh, ich just read the license:
BY -> Attribution required (This is actually not that easy, license material is created automatically in our company, you would need to store and use that information)
SA -> Share alike when modified (This seems to be an issue)
Correct me if I am wrong, but doesn't it actually prevents commercial usage in a proprietary piece of software?
I think it depends where you use it. Anything trivial (a line or two) I think is basically fair game (notwithstanding things like the true binary farce, etc.)
If it's a function and you're doing more than change variable names then you should credit the author and share changes, but you don't have to open source your whole application.
I think, anyway.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
