  • For anyone who is confused: This is exploiting an old soundness bug in the Rust compiler that is still present. The GitHub issue page has this comment from maintainers:

    we already had a crate published on crates.io before which used this bug to transmute in safe code, see #25860 (comment).

    this issue is a priority to fix for the types team and has been so for years now. there is a reason for why it is not yet fixed. fixing it relies on where-bounds on binders which are blocked on the next-generation trait solver. we are actively working on this and cannot fix the unsoundness before it’s done.





  • For anyone who is still confused about what causes this: Firefox launches copies of itself when creating new website instances (usually when loading a website that has not already been loaded). Because of this, if it is updated in the background (through any means; I usually see this after a manual system update), Firefox has to restart when you try and load a new site because it cannot create any compatible copies of itself, since the old version is the one that is still running and the copies would use the new (updated) version.

    The solution is to only update when Firefox is closed, or restart it when it asks.










  • I think the behavior could actually make sense with real physics, as the vehicle might be designed to mimic what the driver expects rather than real physics. For example, my car often shuts off the engine when I am not accelerating because it is a hybrid. So, if I don’t press the gas pedal, it wouldn’t really make sense for it to move. However, it is designed to artificially engage the engine when none of the pedals are pressed to more closely mimic the behavior of non-hybrid cars.

    If most pilots are used to the behavior if a vehicle in atmosphere, a space ship might be designed to mimic that behavior (through weak reverse thrusters or something else) to make it easier for pilots to get used to.
