  • I know a guy who spent 40+ years in special effects. He now goes around giving talks/demonstrations about it all. He has a series of photos showing how a typical car is rigged to explode into a fireball.

    Depending on what the director is looking for, steel horns are welded to the car frame inside each door, the hood, trunk, windshield, etc. The horns will direct the fireball out the car when ignited. Each horn holds an explosive similar to gasoline connected to a detonator.

    After that, each window is wired with a squib, a small explosive smaller than a coin that will shatter the window about 1/10th of a second before the fireballs are ignited.

    If necessary the hood, trunk, and/or doors are also wired with smaller explosives to pop them open immediately before the fireball as well.

    All those smaller explosives are needed to get the doors/windows out of the way for the main fireball explosives. The fireball doesn’t have enough punch to push the doors open on its own, and it also provides significantly more control of the whole explosion. (You’re not guessing where the windshield might get blown to, etc).





  • Proper hashing of a password includes a salt that should be kept private. This means the password should definitely be passed to the server in plaintext. The server adds the salt to the password, then hashes it.

    This adds more protection should an attacker somehow manage to get access to your hashed passwords. Even if they identify the type of hashing mechanism used it will prevent the use of rainbow tables, dictionary attacks, etc. against the hashes.















  • Even in a very optimistic timeline it would take years for Tesla cars to suck less. I don’t think Tesla has that kind of time any more, now that there’s growing competition from big automakers like Honda & Toyota as well as Hyundai, Volkswagen, etc. and all the other EV companies like Rivian.

    Those established automakers have a long history of innovating & listening to customers. As their expansion into the EV market grows, they’re going to put a lot of pressure on Tesla to innovate as well, and that doesn’t mean bowing to whatever whims the CEO has.
