There is surely a profit and a lot of fun around here, but indeed there was a "ptrace - Playing Debugger Chess" lecture by you, http://www.haifux.org/lectures/115/ I don't know who has a profit here (and who has fun...)

Certainly ptrace has been used to both trace and modify running binaries, by gdb, strace, dumpmem[1], memfetch[2] and others. I think I even gave a haifux talk on run-time modification of programs using ptrace for fun an profit a few years ago. > The lecture will look at fakeroot, fakechroot, fakeroot-ng and > strace, at varying degrees of depths, mostly because all four chose > slightly different approaches for solving, fundamentally, the same > problem. They did? Sounds like an interesting talk, will try to attend. [1] http://www.mulix.org/dumpmem.html [2] http://lcamtuf.coredump.cx/soft/memfetch.tgz Cheers, Muli
