The software back then was written in Fortran, the predominate technical programming language a half century ago.

Three Wordle Assistants 3

When I tackle a Wordle puzzle, I like to make all the key decisions myself. My three assistants set up puzzles and suggest words when I ask for help, but I guide the actual solution. My assistants also make it possible for me to play Wordle anywhere, anytime, even when my laptop is in airplane mode. I don't need the New York Times or access to the Web.... 更多内容 >>
