One of the virtues of J is its conciseness; I think this is underrated in exploratory programming. Here I present some J one-liners alongside samples of other languages.
I stumbled across a comment by András Kovács on compiler performance, which brought up some of the difficulties writing adequate compilers in lower-level languages such as C++ or Rust.
Recently, a preprint by Hall et al. was published: a comparison of keto and plant-based diets. The gist of it is that a low-fat plant-based diet is more satiating than keto; those eating an unlimited plant-based diet will eat less than those eating an unlimited keto diet.
I have seen "strict data structures, lazy functions" bandied about among Haskellers. This is bad advice. Preferable is "know what you are doing."
Compared with Rust, ATS provides better type safety at the boundaries; foreign functions and data structures can be used in a first-class way without sacrificing type safety.
