I spent an afternoon vibe-coding a multiplayer game with @multisynq.bsky.social and @threejs.org using Gemini Pro 2.5 – 100% AI coded, although I had to explain how to correct the errors. Zero server code, client-side multiplayer. Live and source on @codepen.io: codepen.io/codefrau/ful...

You wouldn’t believe how long it took me to find my very obvious typo 🤦🏻‍♀️ The symptom was that the output looked red and white 🔴⚪️ when it was supposed to be rainbowey 🌈

$#version 300 es in ivec2 xyIdIx; // position in upper 16 bits, id and index in lower 16 bits uniform vec2 screenScale; // half width/height of screen uniform float spotSize; // size of spot uniform uint colorIdx; // start of spots in display table out vec3 v_color; // color of spot vec3 hue(float h) { h = mod(h, 1.0); float r = abs(h * 6.0 - 3.0) - 1.0; float g = 2.0 - abs(h * 6.0 - 2.0); float b = 2.0 - abs(h * 6.0 - 4.0); return clamp(vec3(r, g, b), 0.0, 1.0); } void main() { ivec2 pos = xyIdIx >> ivec2(16, 16); // sign extend 16 bits to 32 uint idx = uint(xyIdIx.y & 65536); // 16 bit index if (idx < colorIdx) { float fraction = float(idx) / float(colorIdx); // map to [0, 1) v_color = hue(float(idx) / float(colorIdx)); // color by table index } else { v_color = vec3(1.0); // default: white } gl_Position = vec4(vec2(pos) / screenScale, 0.0, 1.0); gl_PointSize = spotSize * 512.0 / max(screenScale.x, screenScale.y); }$

“in terms of program debugging difficulty the problem was a lulu.” — Ivan Sutherland (1963!), “Sketchpad,” pg. 76

$In concept the edge detection problem is trivial. In terms of program time for lines and circles the problem is a small fraction of the total computational load of the system, but in terms of program debugging difficulty the problem was a lulu. For example, the computation of the intersection of a circle with any of the edges of the scope is easy, but computation of the intersection of a circle with all four edges may result in as many as eight intersections, same pairs of which maybe identical, the scope corners. Now which of these intersections are actually to be used as starts of circle arcs?$

I figured out how to keep my fixed-aspect canvas centered but as-large-as-possible in pure CSS 🥳 (I didn’t want to use object-fit because it distorts JS event positions) Try it here (resize the window or turn your phone) codefrau.github.io/Smalltalk78/...

#canvas {
width: auto;
height: 100%;
}
@media (max-aspect-ratio: 4/3) {
#canvas {
width: 100%;
height: auto;
}
}

This is one of the many awesome projects you can play with at squeak.js.org/etoys/ which has the 2005 version of Etoys running on my virtual machine. It’s in the Project Gallery (3rd row, 3rd item)
