APL was designed to be written on a chalkboard (if I remember the story right). It is quite dense, and programs are quite small. Reading is slow and requires you to ponder about what was written. You can hold a lot of content in a small amount of 'ink'.
Now, an idea: HN is always complaining that an ipad (or any other tablet) is a consumption device, as it is not designed to be used with keyboard/mouse. Do any of you know if there is an app where you can write APL with a stylus, and has the ability to evaluate expression on the fly, similar to a repl? That would be an awesome thing to do.
Author here. D’oh! Thanks for catching that. I have no idea what I’m doing web dev wise and made this site to talk about my APL experience. Will try to fix this when time permits.
I see nothing wrong here: Firefox and Chromium are both happy.
