For VoIP applications, one-way mouth-to-ear delay should ideally be less than 150 ms for natural conversations [1].

Other factors, such as jitter, transmission delay, queuing delay, etc., also impact quality. However, if the delay occurs mid-transmission (e.g., due to network congestion or routing inefficiencies), there’s little that can be done beyond optimizing at the endpoints.

Firefox 58 9 years ago

Hey @godelski, I had that issue in Firefox 57, but it seemed to have gone away with 58. Just FYI - I tried altering a bunch of `about:config` non-default settings, but none of them helped. Thanks.

Is this prime? 10 years ago

If you don't want the browser to freeze ...

    var target = document.getElementById('n');
    function detect() {
      n = parseInt(target.firstChild.nodeValue);
      if (typeof n === 'number' && is_prime(n) === 'prime') {
        console.log('>> YES,' + n + ' is prime, clicking "yes" ...');
        document.getElementById('yes').click();
      } else {
        console.log('>> NO,' + n + ' is not prime, clicking "no" ...');
        document.getElementById('no').click();
      }
    }
    var observer = new MutationObserver(function (mutations) {
      mutations.forEach(function (mutation) {
        window.setTimeout(detect, 500);
      });
    });
    observer.observe(target, {
      attributes: true,
      childList: true,
      characterData: true
    });
