Wonders of coding (not exactly the same as wonders of programming):
1) Edition 7 UNIX -- it was a wonder for what it did on such tiny-resourced machines.
2) FORTH -- great power in a small space
3) PDP-10 (DECsystem-10) TECO -- text editor in 4K words of memory.
Microcode - the process of developing a specific series of transistors to become a microprocessor.. The core of the magic. Especially how one can start up a microprocessor from pushing an on switch - that's the definition of sublime to me
8-bit/Microsoft BASIC - many a programmer today can draw their roots back to BASIC. It was the languages that made significant inroads to elementary-high school programming education as well as self-taught programming education.
Python
Metasploit
The Linux Kernel
At the lowest level programming allows us to use code to control machines mechanically thats a wonder.
