Y'all have got to check out the color palette widget wizardry of David Aerne. Seriously, the guy's prolific. The first link is similar to OP's, an image color palette extractor:

Ah! Sorry, I misunderstood, I thought the above comment was saying Meta was behind the open source exemption

Were fonts always able to do "texture healing"? Has no one tried this before?

In case anyone's wondering, this website's syntax highlighting color scheme is called "gruvbox", which I quite like but took an embarrassingly long time to track down

Since Apple turns 50 this year, I went looking for a graphic that symbolizes what I always liked about Apple and the Mac, without implying I condone anything I dislike about them.

Here's my vector reproduction of the logo for MacAddict's and Guy Kawasaki's "EvangeList", circa 1997 :

We also typically value things that are not tied to productivity/output, like product quality/reliability, security, and our own agency.

I want to be free to read, write, run, and share code, now and in the future. Relying on centralized services to do it for me (by extracting knowledge from countless other people) is certainly not a resilient strategy.

This article's from 2021. Does anyone know if there are elements (no pun intended) of this classification of element origins that's impacted by those JWST observations of complex early galaxies?

I contributed one earlier this year! The community's a great bunch and I learned a lot.

Always remember, folks: the best feature request is a pull request ;)

Sorry, I was cracking a joke about the browser in a shader.

The GLSL I originally posted is from the "cursed mode" of my side project, and I use it to produce a data URI of every frame, 15 times per second, as a twisted homage to old hardware. (No, I didn't use AI :P )

https://github.com/Rezmason/excel_97_egg

That said, is `pow(vec4(2),-vec4(2,4,6,0))` really so bad? I figured it'd be replaced with `vec4(0.25, 0.0625, 0.015625, 1.0)`.

base64 is embarrassingly parallel. So just pipe it to the GPU:

  precision highp float;
  uniform vec2 size;
  uniform sampler2D src,tab;
  void main(){
    vec4 a=(gl_FragCoord-.5)*3.,i=vec4(0,1,2,0)+a.y*size.x+a.x,y=floor(i/size.x),x=i-y*size.x;
    #define s(n)texture2D(src,vec2(x[n],y[n])/size)[0]
    #define e(n)texture2D(tab,vec2(a[n],0))[0]
    a=vec4(s(0),s(1),s(2),0)*255.*pow(vec4(2),-vec4(2,4,6,0)),a=fract(a).wxyz+floor(a)/64.,gl_FragColor=vec4(e(0),e(1),e(2),e(3));
  }

Bravo! I love color and color spaces.

I've been researching the way classic Macs quantize colors to limited palettes:

https://rezmason.net/retrospectrum/color-cube

This cube is the "inverse table" used to map colors to a palette. The animated regions are tints and shades of pure red, green, and blue. Ideally, this cube would be a voronoi diagram, but that would be prohibitively expensive for Macs of the late eighties. Instead, they mapped the palette colors to indices into the table, and expanded the regions assigned to those colors via a simultaneous flood fill, like if you clicked the Paint Bucket tool with multiple colors in multiple places at the same time. Except in 3D.

hundredrabbits' game Verreciel uses a reimplementation of webgl-lines, to pretty good effect, if I may say so:

I think of bone conducting headphones as the most realistic foundation for augmented reality on the market. Hearing things without plugging your ears up, weighing you down or taking you out of your surroundings is underrated and underutilized. To match the weight of an Oculus Quest 3 on my head, I'd have to wear seventeen pairs of Shockz OpenMove. Compare the dread of a video ad over your eyes to the dread of an audio ad in your ears.

We really should have a broader conversation about the practical applications of this stuff.
