Any app I write has to run on ALL unsophisticated and unsuspecting CPUs from a brief non-debounced contact closure, beginning with the Motorola 6800.
I can count to numbers higher than five with one hand by using a natural positional representation. With two hands, I can count from 0 to 1023. The "thumbian issues" had to be resolved via an agreed upon convention very early on. Alas, my toes are insufficiently agile to permit me to easily reach 1,048,575. (Incidentally, the fox at the next table just caused my sign bit to become set.) FWIW, that is not a gesture of disrespect that I am displaying. It is unambiguously the number FOUR. On the other hand, it would be 128, and together they would represent 132 (the number of columns on a page of greenbar paper).
Context is everything. Some words have been overloaded. Learn what they are and move on. Consider "moment". http://en.wikipedia.org/wiki/Moment
Ambiguity is as intolerable as intolerance itself, and disambiguation comes in many guises. In some situations, the type of a variable is not known until "execution time". Dismiss my diatribe if you will. I'm just an aging manipulator of symbols that switched to using Macs when Apple switched to using BSD.
Will you still need me, will you still feed me, when I'm sixty-four?
