If you want to contact us about DWARF-hacking, the talk, or anything else you can shoot an email to James at electron100 _at_ gmail.com or to Sergey at sergey _at_ cs.dartmouth.edu. We'll be happy to answer any questions, show you how the DWARF bytecode works, or discuss projects of possible mutual interest.
Below you will find the slides and demo from the Shmoocon 2011 and Hackito 2011 talks. The two talks were essentially the same, the Hackito one has some slightly updated information.
git clone git://katana-patcher.git.sourceforge.net/gitroot/katana-patcher/katana-patcherNote that the main page, hosted by the kind folks at Savannah lives at katana.nongnu.org. If you're interested in Dwarf hacking however, that page won't be of much use as it currently only documents Katana's other purpse as a hot-patching tool. James will be updating the documentation up there shortly.
