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!

Tesla further screwed the pooch with a previous steering wheel that was much smaller and rectangular. It made navigating parking lots and restricted spaces like that a huge challenge for those cars! A lot of people went to junk yards and bought full-sized steering wheels from totaled cars and replaced their own.

Date: 2023-03-16 06:00 pm (UTC)Yeah, I think it's similar to the style used by top fuel dragsters, the ones that do the quarter mile runs with the humongoid tires on the back? Ludicrously impractical for a street car. The dragsters only need limited steering - when they are turned around, pit crew just picks up the front of the dragster and pivots it. And belated Happy Birthday, Jon! I hope you had some fun.

Date: 2023-03-22 09:24 pm (UTC)The CPU normally has a heat sink and fan to remove excess heat from it. 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.!
