thewayneThis is amazing. Tesla has wireless entry through their smartphone app, or you can wave a bar code under a scanner built in to the driver's mirror. They might also have a fob, I'm not sure. Anyway, Driver A walks up to Car B, it unlocks and starts for him. And he drives off. Then he notices a huge crack in the windshield and his phone charging cable isn't there!
Driver B walks up to Car A, it unlocks and lets him start it. He drives off, notices the crack in his windshield isn't there and there's other stuff in his car that he didn't recognize!
Fortunately Driver B found a piece of paper with A's name and phone number, called him, and eventually they got together, exchanged cars, and had a laugh and lots of puzzlement. They contacted the police who said 'no harm, no foul' and to go away.
But guess what. Now that this flaw is known, every criminal hacker is going to be probing for how to exploit it. And they will succeed.
The ridiculous thing about this is that it was so easily preventable. Presumably Tesla has some sort of an encrypted key exchange going on to try to prevent it, and clearly failed. All they had to do was add the VIN to their secret key and you'd be largely guaranteed that only people whom you wanted to have access to your car would be able to unlock it and drive it.
I sent this article to a friend who had one of the first generation Tesla Roadsters, back before the Muskbrat turfed the inventors. He sold it after I told him about a serious flaw that was threatening all Teslas, which would cost him probably $4,000 or more to remedy. He bought a maxxed-out Toyota Avalon Hybrid, which he absolutely loves. It has a very interesting security feature: lock the door with a key, and the wireless remote won't work!

With a water-cooled system, a block is mounted atop the CPU with hoses or pipes and it literally cools the CPU with water! Water circulates, moves the heat away from the CPU, and I guess there's a reservoir and heat sinks to cool down the water.

Date: 2023-03-24 08:58 pm (UTC)It's pretty wild, period. The process of water-cooling CPUs has been around for ages and gotten progressively better. This is the first time that I'll have one, though I think some friends have tried it with varying levels of success. Since I'm buying this computer from a store and not building it myself, I have support and a warranty if there are any problems.!
