People read this? That's cool.

I make code things that draw things. I try hard not to build on top of quicksand. Not a big fan of jerks.

In light of WebGPU, I respectfully disagree. Because it has us building shader modules, buffers, and pipelines up-front with descriptors, the task of figuring out why something isn't working is often front-loaded. Pair that with its eloquent warnings (in comparison to, like, gl.getProgramParameter(shader, gl. COMPILE_STATUS) ) and the ability to label all your stuff to see it referred to by name in aforementioned warnings text... I'm rambling, but, there's just a lot of helpful stuff in WebGPU that I don't think OpenGL has, that stands to really help newcomers along

I don't have an answer, I'm just wondering out loud.

Cone cell activation is complicated. Displays with three well chosen primaries are economical and effective, but they aren't intended to produce every perceivable color. And our chromaticity diagrams, that pointy splotch that's often used to compare display gamuts, is based on a "standard observer" that is a simplified model for human perception.

An ideal pixel would be able to emit any kind of electromagnetic radiation of any intensity, kind of fun to think about but unrealistic and impractical.

What additional primaries mathematically do is expand a gamut from a triangle to a convex polygon. While ten or a hundred primaries would be bonkers, I bet we could fit a quadrilateral or a pentagon to the perceivable gamut in ways that'd see some gains.

Very creative!

Does anyone else besides me suspect X11 will outlive visionOS?

A great writeup of excellent work!

The flight simulator / magic carpet easter egg in Microsoft Excel 97 used that same shaded-colormap palette trick, plus some dithering:

I'm impressed by your sprite pipeline and gibs animations. Your attention to detail and navigation of constraints have really paid off, I can't wait to play this sometime

> If Meta is liable for when someone underage uses their service, then Meta is going to require proof of age—

Let's be clear what this means, "Meta is going to require" something. They'll require it to continue to do something, which is namely to be a bad company, running bad services, without pivoting to something else.

Of course, no one requires Meta to continue to be Meta. We'd protect people by requiring companies like Meta to request PII outright, because then the user is explicitly prompted to decide whether using Meta's services is worth surrendering their privacy. And if consumer sentiment and market forces mean anything anymore, that will incentivize Meta to replace their bad services with better ones, ones that don't cause them tricky liability issues.

In other words, forcing operating systems to demand PII from users from the get-go, regardless of the quality of that signal, and to broadcast that to any website, is not, as you put it, "the way to do it with the least impact on privacy and anonymity possible", etc etc. The "way to do it" is to phase out this rotten era of surveillance apparatus disguised as social media companies.

Sorry for being irate, it just feels like so many people these days arrive too quickly (for my taste) at conclusions without testing certain popular assumptions about the inevitability of tech oligarchy.

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:

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.

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 )

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));
  }
