  • I used to port forward, but I have stopped doing it. I don’t want to have open ports on the same IP that I use for internet browsing.

    I have my local server connected, via WireGuard, to a cheap nearby VPS. All my services are exposed from that VPS.

    This configuration also offers full portability to my home server, allowing me to switch to any ISP, or even move to mobile data, if I have to.

    For applications that require even lower latency, like remote gaming, I use Tailscale, which can traverse the NATs and create direct connections between the devices.




  • Let’s break it down…

    The distance, between the traffic light and the cab driver, should be approximately 10 meters.

    The time light needs to reach the cab driver’s eyes is:

    D ÷ c = 10 ÷ 299,792,458 = 0.0000000333… seconds = 0.0000333… milliseconds

    The distance between the cab’s horn and your ears, should be approximately 5 meters.

    The time needed for the cab’s honk sound, to reach our ears is:

    D ÷ u = 5 ÷ 295 = 0.0169491525 seconds = 16.9491525 milliseconds

    If the cab driver had a reaction time of zero, it would still take 16 milliseconds for us, to hear their honk.

    The conclusion is that cab drivers have a negative reaction time, so that they can honk before the light turns green, breaking causality.
