Similar article I read 10 years ago that covers some of the same ground, with some pretty SVG's as well. http://strangelyconsistent.org/blog/train-tracks

I also use this one everyday. I learned the quick one back in the day, but I value never ever having to stop and re-tie my laces.

Under the "Countries Visited" section it says "been lucky to run on all seven continents, including antarctica!", but it doesn't look like they've been to Australia.

Answering for myself, I started looking into APL, but at the time, learning the keymaps for the symbols seemed difficult, so I started learning array lang techniques with J, and ended up liking it. Some of the knowledge you acquire from one

I was also a big fan of the Panorama feature that used to be built in. These days I'm using the Panorama Tab Groups [1] extension, which provide a practically identical experience the the old built in Panorama. [1] https://a

FWIW, I solved this in J as follows F =: >@{.@(\: #@>)@(#~ (2 >: +/@e.&'aeoiu')@>) which I think maybe composes a little better This doesn't include the splitting. I would imagine I would be feeding this

Another Unicode article that mentions Swift, but not Raku :( Raku's Str type has a `.chars` method that counts graphemes. It has a separate `.codes` method to count codepoints. It also can do O(1) string indexing at the grapheme level.

I know cygx already replied, but to be clear, function signatures have been available in Perl since 2015. They were added (as experimental) in 5.20, and are now enabled by default with `use v5.36` or later. All new features must now go thro

This is exactly what Raku does. Neither strings nor arrays have a `.length` method because it's arbitrary. [0] > "\c[FACE PALM]".chars 1 [1] > "\c[FACE PALM]".codes 1 [2] > "\c[FA

The closest thing these days is probably p5js (Processing in JS). function setup() { createCanvas(640, 480) } function draw() { background(0, 100, 200) strokeWeight(100) stroke(200, 200, 0) line(

I'll repeat the sentiment that "always" and "never" rules usually have their fair share of exception. And while I agree that [closed, open) intervals are often the best choice... sometimes what you want is [closed,

One potential use case could be in creating bindings for other languages that do not have an expect like module. Since it reportedly has a "saner interface than libexpect", it might be less hassle creating FFI bindings to mini-exp

The first operation where I split to lines, then join, then split again... was annoying me. So now I've got this say qx< cal -hy >.lines.skip.batch(9) .map({ |([Z] .join.comb(22).batch(3)) }) .map({ |(.[2] ~ .[0].trim

Just for fun, I tried it in Raku. say qx< cal -hy > # Command output as string .lines.skip.join("\n").split(/\n\n+/) # Skip year & split groups .map({ |([Z]

Raku also has a specific string type (Str) that is not just a bag of bytes. Strings are normalized (NFC) when they are created, and multi-codepoint graphemes are represented internally using synthetic codepoints (negative integers), but thi
