The neon effect with javascript P5 JavaScript library.

The P5.js is a JavaScript library for creative coding.
You can use by adding this link on your HTML area using the script tag:
https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.9.0/p5.min.js
You can use it like any JavaScript library.
You have two functions: setup and a draw for setup and drawing.
function setup() {
  createCanvas(window.innerWidth, window.innerHeight);
}

function draw() {
  ellipse(50, 50, 80, 80);
}
Then you can fill these functions with any javascript code.
You can see a neon effect with two bezier functions.
The example uses the mouse movement to change the bezier lines.
You can see many examples created by me at codepen website.

This is the output:

NVIDIA video cards and CUDA feature.

Today I search on web information about video cards for processing, neural networks, and rendering.
If you use it with Blender 3D software or Neural networks then you need a GPU with CUDA feature.
My destop works with an old NVIDIA Corporation GT218 [GeForce 210] (rev a2) video card and this not help me very much.
The CUDA platform is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements, for the execution of compute kernels. see Wikipedia.
This software uses the CUDA feature. Let's see all of these informations about desktop Nvidia GPUS ordered by CUDA core count.
