However, current tools assume that the last developer to change a line of code is its author regardless of all earlier changes. This approximation loses important information. We present two new line-level authorship(More)
Code reuse attacks circumvent traditional program protection mechanisms such as W ⊕ X by constructing exploits from code already present within a process. Existing techniques to defend against these attacks provide ad hoc solutions or lack in features necessary to provide comprehensive and adoptable solutions. We present a systematic approach based on first(More)
Parallel tools require common pieces of infrastructure: the ability to control , monitor, and instrument programs, and the ability to massively scale these operations as the application program being studied scales. The Paradyn Project has a long history of developing new technologies in these two areas and producing ready-to-use tool kits that embody these(More)

Notwithstanding the immense number of these creatures constant!}' under observation in the zoological collections of Europe, it is a curious fact that only about half a dozen examples of(More)
Consideration is given to the regular recording of parathenar distal loops (Pa) and hypothenar radial arches (Ar) in palmar dermal topology. Frequencies are given for four British populations (the North Pennine Dales, the Mid Welsh Borderland, Pembrokeshire and Ireland) and regional variation noted together with sex and bimanual differences. Both Pa and Ar(More)

Modern principles of treatment differ so widely from those hitherto prevalent, that I deem no apology necessary for(More)
