What are the open-source code hosting sites for projects with closed-source dependencies?

It actually doesn't matter much if your project depends on proprietary components, as long as you don't version these components on the source control under discussion.

You can put your code on a "commercial" site like Bitbucket or GitHub.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
