Notes:
Thank you all for a great semester.I am not teaching ODE’s this term.
DRM attacks your freedom at two levels. Its purpose is to attack your
freedom by restricting your use of your copies of published works. Its

control what it does. When companies organize to design products to
restrict us, we have to organize to defeat them, >>>more
