Forks: Spoon fed

This just a short article explaining how forks work in Dyalog APL. Some basic knowledge of APL is assumed but not much more than can be attained by browsing an introduction to the language.

I should say that this will be opinionated. It’s not meant to declare what is but rather my take on what is. Feel free to read “as I see it” before every sentence. Further, this is meant for beginners. It attempts to present a framework for thinking about this tool and not as a historical reference on the development of it. It’s similar to learning a Chinese character and thinking “that looks like a mouse!” Even if that’s not the origin of the character, if it helps you remember it then it’s worth latching onto.

Let Ǎ, Ǐ, Ǒ be triads +, ÷, × be dyads A, I, O be monads 1, 2, 3 be nilads

Migrating from Ubuntu on WSL to ArchLinux on WSL2

Obsolete notice

This document was created back in 2020 and might not be actual nowadays. It is not supported anymore, so use thise information at your own risk.

Upgrading to WSL 2

Download WSL2 Kernel
run wsl --set-default-version 2 in windows command line, so that all future WSL machine will use WSL2.

k tech tree

Thought experiment:

Which k primitives can be implemented as k-strings, reasonably efficiently, with a handful of 'native' built-ins?

Not verified to be in dependency order yet... may depend on the choice of 'fundamental' primitives. Need to do speed tests too.

k9 syntax (download via Shakti). Got a better way to write one? Feel free to comment, you'll be credited!
