Does anyone know the font & colorscheme being used in the code snippets?
No idea about the color scheme but it's nice.
Unrelated to any of this, this font reminds of an old Turbo Pascal program I wrote years ago (decades now) to extract a VGA font from the computer's ROM and use the character bitmaps in my own graphics programs. Nice memory I would not have had if not for your question, so thank you!
