  • That’s not quite accurate because the two numbers have a relationship with each other. i^2 = - 1, so any time you square a complex number or multiply two complex numbers, some of the value jumps from one dimension to the other.

    It’s like a vector, where sure, certain operations can be treated as if the dimensions of the vector are distinct, like a translation or scale. But other operations can have one dimension affecting the other, like rotation.





  • Yeah, I sometimes wonder why the European and Japanese fascists even allied.

    I’m doing a hearts of iron 4 playthrough as germany and just said no when the option of allying with Japan came up. It’s that alliance that ends up pulling the US into the war. This way I think Japan will have their own little war with the US and China while I fight it out with Britain and finish that up before even looking at the Soviets funny.






  • Even knowing about it, each time I look deeper into it, I realize it’s even worse than I had thought it was.

    Key takeaways from skimming that link:

    Agencies assume the oral route is the primary one of concern, but most BPA consumed orally ends up processed by the liver into a form that doesn’t bind to estrogen receptors. This is not the case for BPA absorbed through the skin.

    Safety assumptions for skin absorbed BPA assume best case scenarios. If any factors are less than ideal, actual absorption could be significantly higher than the numbers used to determine it’s “safe”.

    If you work in retail where you need to handle these regularly, you should wear gloves because those safety assumptions also seem to mainly consider the habits of customers who receive one with a purchase, not the people who need to rip one off for the customer and another for the business and then maybe handle ones to do paperwork when closing the till.

    Also it didn’t really go into the amount that might get airborne and inhaled due to handling those receipts.

    Hopefully it’s not a big deal, but that is currently more based on wishful thinking than any real scientific backing.




  • Grim Dawn has a similar approach. You just have a health and energy potion that goes on cooldown. No need to worry about potions for inventory management or remembering to buy them in town or checking if you need to pick some up, plus less loot clutter because of it. The potions return a % of hp/energy, so they scale with your character. And it helps with balance because now those players who do farm tons of potions so they can spam them don’t need to be considered.


  • (Agreeing with you but adding relevant information)

    Hitler did come to power after trying to lead a (potentially) violent coup Mussolini-style (but it was stopped, in part due to incompetence of the nazis) and his trial for that gave him a platform on the world stage that increased his popularity. And then he wrote Mein Kampf while in prison.


  • Lots of good advice in here for the basics. Only one I’ll bother repeating is to get used to your clutch by slowly releasing it and getting the car moving without touching the throttle at all.

    Also never downshift into first. This is a bit of a soft rule since it can be done, but the speed you need to lose before you do is a lot more than any of the other gears. If it’s a 6 speed, this might even apply to 2nd gear to a degree. To figure out when it’s safe to downshift to first, redline it in first and check your speed. Never do it at or above that speed as a hard rule.

    For intermediate techniques:

    When shifting while moving, let off the gas a bit before pressing the clutch. The idea is to smoothly stop accelerating to reduce the jerk you’d normally get from going from accelerating, clutch (decellerating), back to accelerating once in the next gear. Your passengers will appreciate it if you can get this timing down, though if you’re on your own, it doesn’t matter as much since you can anticipate the changes in acceleration.

    On the opposite end of that spectrum, practice speed shifting once you’re comfortable with clutch timing and gear positions. It’s the same motions as a normal shift, just aiming to do it all as fast as possible. It’ll give you better acceleration when you need it (very noticeable if you compare one and the other when accelerating beside another car from a stop light).

    For stop and go traffic and traffic jams, instead of maintaining the same distance from the car ahead of you, try to figure out a constant speed you can maintain and let the cars ahead of you do the pull up (away from you) and then brake to a stop (while you slowly catch up to them). If you can find the right speed, you can stay in first gear instead of needing to get in gear, move up, then clutch. The “getting the car moving without throttle” skill from earlier can help here and sometimes you can go a while in a jam without touching the gas pedal. It’ll reduce the wear on your clutch and brakes if you can drive in a way that uses them less.

    And an advanced technique:

    Clutchless shifting. If there isn’t a lot of force on the gear, you can pop it into neutral without the clutch quite easily. And by force I mean if you aren’t accelerating or engine breaking. Getting into another gear is harder but also possible. The hard part is that you need to match the engine speed with the transmission speed for the gear you want to shift into. If they match, it’ll just slip in. But matching is easier said than done, since the car is decelerating and the engine also changes speed very quickly with no load. If the speeds are far from a match, it will feel like the gear just isn’t there. If they are kinda close, you’ll be able to find the gear but it will grind when you try to put it in all the way. If they match closely, it’ll just slip in as easily as it slipped out to neutral.

    Why would you want to know how to do this? Well, for one, it’s very satisfying to do properly. But I was very glad I could do it when my clutch died. I was able to drive for another week without a clutch because I was competent enough with clutchless shifting. Note that if you need to do this, you have to turn your motor off when you stop (unless you’re on a downward slope), put it in first and start it in first gear to get moving again (which feels awful and is awful for your starter and probably not great for the whole drivetrain, so get it serviced asap but this might at least save you from needing a tow).


  • Lemmy is only better than reddit in that it was designed to work around the fact that humans can be shitty, even if they were previously not shitty, so a platform that can spread authority around rather than consolidate it in the hands of a few will offer alternative options even if an admin or team of admins becomes shitty.

    It means that Lemmy has the potential to be more extreme in any direction as much as it has the potential to be less extreme in any direction. No one can dictate what all of Lemmy is but anyone can dictate what small pieces of it are.
