As the funding for my research largely comes from public sources, I feel it's important for the public to benefit from the work I do. Where possible, my code is released under a BSD license (not just as a historical hat-tip to the University of California, but because I feel reciprocal licenses aren't good). The source code for my released work can be found at GitHub, which also hosts an issue tracker. I very much doubt you are interested in the source of my projects, let alone filing bug reports, but feel free to fork all night long!
