I'll third the ArrayCast, the host is Conor Hoekstra, a C++ programmer at NVidia Research. Regular panelists are Adám Brudzewsky[1] who works at Dyalog APL, Bob Therriault[2] who runs the J Wiki[3], Stephen Taylor who works with K and Q and cut his teeth on APL planning one of Chris Bonnington's Mt. Everest[4], Marshall Lochbaum who worked on J and APL and developed the BQN[5] language.

And their guests include Jeremy Howard, founder of fast.ai and Kaggle, Henry Rich implementer of the J language, Stevan Apter a K programmer and creator of No Stinking Loops site ( nsl.com ), Andrew Sengul who created April a blend of APL and Lisp, Morten Kromberg the CTO of Dyalog APL, Aaron Hsu creator of the co-dfns GPU compiler for APL, Brooke Allen a Wall Street entrepreneur and APL programmer, Eric Iverson son of Ken Iverson the APL creator and J designer/developer, Ashok Reddy former chemical engineer and employee at Rational (the UML people) now CEO of the KX company, Atilla Vrabecz a PhD Chemist turned K language entrepreneur, Leslie Goldsmith former APL developer at I.P. Sharp, John Earnest creator of the Ok language, Troels Henriksen creator of the GPU accelerated language Futhark, Lib Gibson former APL developer and consultant and project/developer manager at I.P.

Note that the author also made a k interpreter [0] which has a graphical env to play around with as well.

This - https://github.com/JohnEarnest/ok - can also be used sometimes...

If you want to try out K, there are some open source implementations, like John Earnest's oK which has a REPL and a calculator-like interface for mobile phones with a charting feature.

and have the programmer use the word "barchart", they instead prefer to use the definition itself. The word "barchart" has a specific meaning (here, an ascii "bar chart" of 0s and 1s, showing the relative sizes of the values of input array x), but "{x>\:!|/x}" might be useful for more than just bar charts. This idiom contains smaller idioms like "count til max" (!|/) which in turn contains "max" (|/).

Being able to see the code makes it easier to explore and tweak to your specific needs. But more importantly, there are no "official" names for concepts like "count til max". That's just my personal name for it. A python programmer would call it "range". You could come up with your own name for (!|/) that makes perfect sense to you. But that name will probably be longer than its definition, and less flexible.

check out oK[0] by John Earnest, who is the author of the content of this post

it is well-written manual and is a great jumping off point

there is a k-enthusiast element.io server[1] where you can ask any question you like. folks are friendly!
