Heat is proportional to power dissipation:

    P = UI

while

    I = U/R

So if R increases, I decreases. But then P decreases too and the IC gets
cooler, hence less resistance. Hmm...

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
