I never made any claims about derivative works.
I thought derivative works was what the discussion was all about, and someone made the claim that an interpreted program is a work derived from the interpreter. >> >> A regular program interacts with the registers, memory and so on >> >> found in the machine, not with the individual gates, electrons and >> >> whatnot that make up the actual hardware. >> > >> > So if I write a program that puts things on the display and reads >> > keyboard input, that is not interacting with the physical device? >> >> The program is interacting with something like an X server.
