    Imagine that you’re standing on a train and have a baseball. If you throw the ball off the train, the ball will still have momentum in the direction of the train’s movement.

    If you want to throw the ball to a friend the train just passed, you have to be able to throw the ball faster than the train is moving or it will never reach them.


  • It’s the only EV pickup than can be reliably charged right now. The one truly remarkable, excellent thing Tesla has done is put together an awesome, connected charging network. We’ve had a plug-in hybrid Ford for a decade, and the vast majority of compatible chargers we’ve run across have been broken.

    With the other big manufacturers changing to the Tesla plug in the coming years, I expect things like the F-150 Lightning to perform much better.

    Fahrenheit literally meant to base the scale with 100 being human body temp.

    It was later rescaled by Cavendish to put the freezing point of water at exactly 32 and boiling point at exactly 212, giving a nicely-divisible 180-degree separation between freezing and boiling. That shift is why body temperature is 98.6.





  • Stop using vehicle footprint for trucks on CAFE standards.

    Starting in 2012 truck fuel economy standards changed to being based on vehicle footprint, which essentially outlawed small trucks and encouraged manufacturers to keep making them bigger and bigger.

    It’s why the Ranger, Dakota, and S10 were all suddenly discontinued. The Ranger eventually came back, but is now bigger than the F150 was before.

    It’s hit cargo vans too. Between 2021 and 2023, all small cargo vans (Transit Connect, Promaster City, and NV200) were discontinued as they got passed by stricter fuel economy standards that penalized them for not having a larger footprint.


  • Most people who carry guns are doing it for self-defense, not civil defense.

    The rules of an Active-shooter event are:

    1. Flee
    2. If you can’t flee, hide.
    3. If you can’t hide, fight back.

    Carrying a concealed weapon doesn’t change that. I have a little 380 pocket pistol I’ll occasionally carry. It’s low-capacity, low-power, and low-accuracy. No way am I volunteering to take on a psychopath with a long gun who isn’t worried about collateral damage with my little pea shooter, and anyone Who expects me too just because I’m armed can kiss my ass.

    I carry a pistol to protect me from muggers and car-jackers, not to protect the public.



  • Not enough detail in the comic to tell whether it’s a striker or hammer-fired pistol.

    Most striker (and some hammer) automatics cannot be decocked without pulling the trigger on an empty chamber.

    And got those that can, you either have to pull the trigger while holding the hammer back and lowering it manually, or by flipping a separate switch or button.

    If it could be done by moving the slide back and pulling the trigger, then holding the trigger down while firing the gun would result in full-auto.
