It looks like it's not actually a design community, contrary to what the title here says. They say on their site: "Search by tag(s) through many tutorials, tools, and assets for developers and designers"

Then they have postings on things such as Vim and programming tutorials.

All told, covers a pretty broad base with some interesting stuff - ColorHexa[1] immediately stuck out to me.
