I was just referring to your 3 definitions of hacking... To hack doesn't necessarily mean to go particle-level or low-level, or learn something from the bottom-up or master some field. And your first comment also gave me the impression that you think hacking can happen only at low-levels, like embedded or electronics. Manipulating and hex-editing a binary... I call it a hack, and congrats, it seems like you are doing it already. Read (or watch) The Martian for one hack after the other, at several levels and different fields.
