APL Problem Solving Competition 2023 Now Live!
Norman Thompson: APL problem solving competition 2023 is now live. Linux format issue 300, which came out this month, has a fairly extensive article on APL and array languages. There's also a new APL show episode of me and Adam talking about APL and sort of it notation as a tool of thought.
