  1. Statut de Christopher Lemmer Webber (cwebber@octodon.social) sur Monday, 30-Nov-2020 04:55:44 CET Christopher Lemmer Webber Christopher Lemmer Webber

    I guess I'm old enough now where I can spout facts like "Well screensavers are called that because back in the day we used CRTs and if you left the same image up, it would literally burn into the screen" and either blow the minds of or supremely bore the youth

      1. Screen burn-in
        Screen burn-in, image burn-in, or ghost image, colloquially known as screen burn or ghosting, is a discoloration of areas on an electronic display such as a cathode ray tube (CRT) display or an old computer monitor or television set caused by cumulative non-uniform use of the pixels. Newer liquid-crystal displays (LCDs) may suffer from a phenomenon called image persistence instead, which is not permanent. Causes of screen burn With phosphor-based electronic displays (for example CRT-type computer monitors or plasma displays), non-uniform use of pixels, such as prolonged display of non-moving images (text or graphics), gaming, or certain broadcasts with tickers and flags, can create a permanent ghost-like image of these objects or otherwise degrade image quality. This is because the phosphor compounds which emit light to produce images lose their luminance with use. Uneven use results in uneven light output over time, and in severe cases can create a ghost image of previous content. Even if ghost images are not recognizable, the effects of screen burn are an immediate and continual...

      @cwebber back in '06 I was at a big LAN. At one point they brought up some volunteers to a stage and let them compete in a quiz-like competition. One of the challenges was "imitate the sound a modem makes when dialing up."

      They all stared at each other, completely silent. None of them had heard a dial-up modem or even knew that modems at one point had made sounds.

      That's the first time I ever felt old.
