Literate programming with a little bit of spatiality

> Conceptually unified — not a “stack”. Heh, I actually drew out the stack under my app recently. A conceptually unified experience is lovely when everything is working. But when things break, it's lovely to know the sub-components you depend on and their relationships. The key is parsimony.

Here's a picture I made as I listened to your scenarios, in case it helps.

You didn't ask me, but I've been building some text-first UIs atop a graphical canvas: git.sr.ht/~akkartik/pe... (instead of left-lines of text that scroll down, each command from a palette appends a column of notes to the right) git.sr.ht/~akkartik/dr... (unconstrained infinite 2D surface)

Circle packing Thanks @ronikaufman.bsky.social for the inspiration (bsky.app/profile/roni...) akkartik.itch.io/carousel paste.sr.ht/~akkartik/ce... merveilles.town/@akkartik/11...

Piet Mondrian, "Composition A" (1923) drawn using just circles. The borders don't really work; the black background accidentally helps improve the effect.

Robert Delaunay, "Rhythme, Joie de Vivre" (1930) drawn using just circles. This one's my favorite.

Vincent van Gogh, "The Starry Night" (1889) drawn using just circles. Impressionism really stresses this approach.

Coming up with a paper notation for kids so they can think about programming without filling up short term memory with irrelevancies like the order to put numbers in. (As is often the case these days, I'm sketching this on akkartik.itch.io/carousel while lying in bed with my phone.)

A screenshot of Lua Carousel showing a mock-up of a new notation, how I imagine it is equivalent to textual function calls, and the result of running the textual calls on a computer.

To draw a rectangle I need to specify the x and coordinate of the top-left corner, and the width and the height of the rectangle. So the idea is to make those numbers labels on a picture of a rectangle.

Crucially, the picture is not to scale. Multiple rectangles aren't going to be positioned relatively, we're just going to put them one below another like a sequence of instructions. We're going to be drawing these pictures with pencil, and we don't want to get too hung up on realism. It's still just a notation.

All the upsets in the Cricket World Cup so far finally got me to build this tool I've always wanted. #cwc git.sr.ht/~akkartik/cr... It's not much to look at, but does the job for me. And if you don't like something -- you can make changes while the app is running! See archive.org/details/akka....

You can now quickly make any app end-user-programmable -- as long as it's built in LÖVE forum.malleable.systems/t/adding-mal...

Screenshot of a text editor showing a little LÖVE app, and a "Run" button below it.

Screenshot showing the running app: a blank screen with a single number in poor contrast -- which increments with every mouse click.

Press any key and you're back in the text editor.

Hi there Twitter, how you doin'. Love the new logo. I particularly love the multi-year guerilla marketing campaign for it. It's the first thing I click on every time I visit you!

Image maps are pretty cool. Particularly when www.image-map.net exists. akkartik.name/freewheeling#resources The only issue: links use absolute coordinates. So <img> can't be resized. Thanks @khinsen.bsky.social for suggesting linking to all the repos in one place.

Screenshot of image-map.net UI for mapping rects in the image to different links.
