Niklaus Wirth and Chuck Moore had a lot more in common than I ever expected to discover.

I've known about both since the early 1980s (Wirth via using USCD and DEC20 Pascal and Moore via various #Forth implementations I used on the Commodore 64).
They seem to be worlds apart, but both:
1. Worked towards simplicity in its purest (but practical) forms
2. Designed their own hardware and programmed them bottom up in their own programming languages.
3. Took more and more away from their languages (stripping down to their bare essentials)

I'm currently hacking using Wirth's #oberon language (target compiling for 8-bit AVR) and the restricted language features of oberon is forcing me to think "differently" in similar ways that #forth does.
