Hmmmmmmm, the topic should probably be
What are your favorite programming languages.. 1/2 dozen maximum. Way too tough to pick one.
The Most Recently Used would have to be:
AutoIt3
AHK
Delphi
C#
C++
Operator overloading is fun so C++ shines there.
AFA learning the most in a short time I guess I'd
have to say 80x86 assembler. It forced me to learn
about the actual hardware and memory addressing,
CPU instructions, interrupts etc..
I'm at 1/2 dozen so I have to quit here.
