Having J on the phone in your pocket is great.

And lots of the "labs" (interactive tutorials) are built in too: 3 dots -> Help -> Labs..

Edit: I should also have mentioned that Termux on android can build ngn-k, goal and a bunch of other open source array languages too.

There's also Rob Pike's Ivy language for Android too.

New comment by liveranga in "Crafting Interpreters with Rust: On Garbage Collection"

Just to throw a positive word out there from one of the quiet majority of your readers, I think you absolutely nailed it with Crafting Interpreters.

It's by far the best introductory book on this topic I've come across yet. It's a fun read and completely demystifies the "magic" of how interpreters work.

There's also a number of different open source implementations of various versions of K listed on the K wiki:

There's also April APL: https://github.com/phantomics/april

Also the array language family seems to be stronger than ever with foss: ngn/k, BQN, uiua, and of course J but as you mentioned they're all different languages.

New comment by liveranga in "Solar will soon eclipse other forms of energy generation"

liveranga — Thu, 01 Jun 2023 11:42:46 +0000

It's amazing watching the live dashboard for Australia's energy grid: https://opennem.org.au/energy/nem/?range=1d&interval=30m

Looking at the annual data is amazing too: https://opennem.org.au/energy/nem/?range=all&interval=1y

In 2022 our electricity grid was 34.9% renewables already, with wind and solar pretty close in proportion.

Thank you for articulating this so well. I've also had a zero-tolerance ad policy for years now. My partner and I refer to ads as Brain-Pollution.

liveranga — Sat, 08 Jan 2022 03:02:59 +0000

Fortran seems to be undergoing a minor renaissance at the moment. Modern Fortran is a fun read and the FPM tool is an attempt at creating an ecosystem similar to cargo for Rust.

I have a copy of Fun Q sitting in the tsundoku pile on my desk that seems pretty good from a quick flick through.

There's a handful of resources around that look fun though I haven't dug into them yet.

There's this on the J wiki: https://code.jsoftware.com/wiki/User:Brian_Schott/code/feedf...

And there's this YouTube series for APL: https://youtube.com/playlist?list=PLgTqamKi1MS3p-O0QAgjv5vt4...

New comment by liveranga in "I got the J language working on OpenBSD"

liveranga — Sun, 12 Sep 2021 20:52:50 +0000

J is definitely more batteries-included than the open source K implementations.

There's also a wealth of documentation and books on J: J for C Programmers: https://www.jsoftware.com/help/jforc/contents.htm

Learning J: https://www.jsoftware.com/help/learning/contents.htm

And the New Vocabulary "Nuvoc" on the wiki: https://code.jsoftware.com/wiki/NuVoc

Edit: spelling.
