lm happy to report that the 'open' verb indeed succeeds. Attempting to open files upwards of '~ home' from the app menu crashes the app, though. Samsung forbids access to everything under /storage/Android/data. There are several filesystem apps that bypass this restriction, fortunately. This allowed me to copy/paste in '~Projects'. As for the user experience, the JKeyboard is really nice but my preferred input method by far is handwriting with Gboard (the Google solution works MUCH better than the stock Samsung stuff). It really feels like doing math on paper, and I can confidently say that this is hands down the best programming experience I ever had on a mobile device (which is not saying much, but still...). Please find some benchmark results on a Galaxy Tab s7 below:
Starting: 2021 10 9 8 50 19.9889 Floating-point arithmetic: min, max, mean, SD: 0.380841 1.25713 0.902903 0.339059 Integer arithmetic: min, max, mean, SD: 0.276258 3.36526 1.78733 1.43478 File writes: min, max, mean, SD: 0.002326 0.043365 0.00792618 0.00815655 File reads: min, max, mean, SD: 2.1e_5 0.057293 0.00760811 0.0133558 Random File reads: min, max, mean, SD: 0.006192 0.044843 0.0186543 0.0135501 Done: 2021 10 9 8 51 18.194 Honestly, I am pleasantly surprised by how good the experience is. I think it might make a stellar video demo to showcase J on YouTube, if someone's interested! Indeed, the terseness coupled with the ASCII glyphs really give J the edge vs. other languages, here!
