Speed, the auto-contradicting senile sociopath, blabbered, again:


How does it know that the earbuds are no longer in my ears?

I was going to say because it can no longer
shine a light from ear bud to the other...

One obvious approach would
be temperature or capacitance.

IOW, you haven't the foggiest, but you will mouth off in your known
"all-knowing" manner anyway, you subnormal senile know-it-all!

"Who or What is Rod Speed?

Rod Speed is an entirely modern phenomenon. Essentially, Rod Speed
is an insecure and worthless individual who has discovered he can
enhance his own self-esteem in his own eyes by playing "the big, hard
man" on the InterNet."
