  • #1 is a terrible idea if you ever need to hire an electrician in the future, plan on selling your house, etc. The National Electric Code prohibits using white, green, or grey wire for a hot/load connection. The 120V cable will contain a black wire for the hot connection, white for neutral, and green for ground. To properly convert it to 240V you would need a cable that consists of black & red wires for the two 120V legs.

    If your home ever suffered an electrical fire then this sort of jury rigging is precisely the sort of thing any competent insurance inspector would spot, and insurance carriers would deny coverage for since it clearly isn’t code compliant, which means a licensed electrician didn’t install it and it wasn’t properly inspected.




  • No, but if somebody like the NSA comes along with a request to intercept a specific package, or even a bunch of packages then customs will gladly turn them over. As was posted elsewhere in this thread, NSA has been known to do this in targeted cases and installed software into routers etc. before returning them to customs for delivery.

    So it truly depends on whether an organization like the NSA has you on their radar.





  • To be fair, the Tesla vision system has 3 cameras facing forward. One in the center above the front bumper grille and two behind the rear view mirror. Those two provide some level of stereoscopic vision to help judge distances.

    But yeah, the lack of other sensors is a huge issue. Anything from bug splatter to mud to snow etc. can easily obscure one or more cameras and render the whole vision system unreliable.

    We also process light differently than cameras do

    To expand on this a little further, human vision has also developed the ability to filter out unnecessary information in order to avoid overloading the brain. When tracking moving objects the eyes mostly send deltas of the movement to the brain. Computers, however, are the exact opposite. The cameras essentially send a series of still images, and it’s up to the computer to compare them to look for any movement.



  • On top of this they are also highly compartmentalized, which sounds like a nightmare to me. A few years ago we ran into a bug with one of their AWS services (I forget the specifics at this point, but it was with a network load balancer). It was a rather novel bug, but easy enough to reproduce, so I was able to give AWS support a working example. They quickly confirmed the bug and said it would be fixed as soon as possible.

    Since it was an odd bug I asked AWS support if they could provide a high level description of the fix once it was implemented. It was then that they told me how their teams were so highly siloed and couldn’t really share details like that with each other. The support rep I worked with wouldn’t even know if the bug was fixed by a load balancer team, a more generic networking team, or some other team. They would only know the bug was fixed.

    If the same geopolitical environment still led to World War II but with a different German leader then the outcome of the war could very well have ended differently.

    Leading up to major invasions like D-Day in Normandy and the invasion of Sicily the allies implemented major deceptions to confuse the Germans. Despite some senior leadership recognizing at least some aspects of those deceptions, Hitler himself fell for them pretty thoroughly and ordered troop movements that reduced German defenses where the attacks took place, and delayed moving them back because he still believed the deceptions were real. There are other examples of poor decisions by Hitler throughout the course of the war that proved helpful for the allies as well.

    If Germany had a more qualified military leader running things then events like the Normandy D-Day invasion could have had a very different outcome. If the Germans had the Normandy beaches better defended then that invasion could very well have failed. And if that happened then there’s a good chance Germany could have won the war.
