The cable is not smart enough to remove viruses but as they say it can suppress some noise effects of them, at least.

Ah those smart marketing people …

Epic discussion: VS Code Uses 13% CPU When Idle Due to Blinking Cursor Rendering

VS Code Uses 13% CPU When Idle Due to Blinking Cursor Rendering

Discussions: Reddit and Hacker News

Couple of citations:

Assuming 1 million users of VS Code This blinking cursor will waste $3 million per year in electricity costs, and output 32,000 tons of c02 per year.

2150: “Grandpa, why did the ocean’s dry up?”
“well sonny, long ago, Microsoft didn’t optimize their code for a code editor’s cursor and pushed earth’s climate over the edge”

TL;DR:

All this is about Microsoft Visual Code editor that is Electron application — Chromium based.

They blink cursor by this CSS declaration:

@keyframes monaco-cursor-blink {
    50% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

.cursor-blink {
    animation: monaco-cursor-blink 1s step-start 0s infinite;
}

Problems with this solution:

  • In chromium / webkit this animation runs with animation frame rate — each 16ms — 60 FPS.
  • As Chromium (WebKit with Skia backend) uses mostly CPU rasterization than simple task of filling 1px rectangle eats CPU (and so drains batteries). On each frame rate whole window gets updated.

In principle all this can be solved by something simple as:

setTimer(function() { caret.toggleClass("visible") }, 1000);

then use the following template:

  • Explain details that you see as much as possible. Environment, problem, etc.
  • Explain exactly what you want – what you think should be happening.
  • Explain what is actually happening.
  • Explain why you think it should be working differently.

By walking through all these steps you may find answer by yourself. In any case this will greatly increase a chance of getting adequate answer fast.
