would a hacker/programmer/etc use Te or Ti more to get their job done? is it more of a this is 1) so, i see that if i do this, it produces this result, so, 2) how do i get through or do this and that.." without without actually needing to understand it... or is it more of an internal deep understanding of the program?

or would it be the programmer who uses Ti more and hacker uses Te more.. or am i so wrong.. i'm just trying to understand Te and Ti differences..
