Hacker News for Applied Mathematicians

Hi, I'm a student who's currently studying computer science and thinking about a double major in applied math.

I'm fairly interested in applied math, and I'm wondering if there are any Hacker News style forums for applied mathematicians (where people talk about applied math, the various industries that applied mathematicians work in, etc..). I realize that this is kind of vague, but it would be great if people could list some forums that seem to fit the description of hacker news for applied mathematicians.
