DyDAn, DyDAn Research Blog
DIMACS has been and will be a good resource for theoretical computer scientists. Independently, a DIMAS-esque, new operation has begun at Rutgers, called DyDAn (Center for Dynamic Data Analysis). Fred Roberts will be the Director, and there will be collaboration between theoretical CS/Stats/Optimization and others. There is a blog in its natal state to discuss mathematical/algorithmic research issues related to DyDAn research.
