From that article:
The catalog launched with more than 60 projects, many of which have an emphasis on organizing large sets of data... and the MIT-developed dynamic language Julia.
...The catalog listing is at http://www.darpa.mil/OpenCatalog/index.html - most of the source items appear to be hosted at github, a few on github.io (an open platform). There is also a catalog of papers.
If the research community responds well to the first iteration of the catalog, DARPA says it will continue to publish information about its projects, including software, publications, data, and experimental results.
Some of the software items are known (to me), so the only thing new is the aspect of DARPA funding (?). Some are extensions / support to known items.
It's an interesting collection in some aspects.
