    The Finnish Air Force swastika is such an interesting case to me, because the moment you do a google for “Finnish air force swastika”, you are blasted with rationalizations: “predates nazism”, “good luck charm”, “innocent”, “unrelated to Hitler”. You get blasted with rationalizations before you can even see the history: which is that the innocent wholesome chungus dude who brought the swastika was Hermann Göring’s brother in law lol.

  • If you want people to trust in this,

    My point is not to run PR for BYD. I’m not trying to get people to trust a corporation. I’m just shutting down FUD (that is most likely rooted in sinophobia).

    Basic physics knowledge? Why would we disregard that based on the word of a corporation whose entire goal is to convince us to buy their products?

    Yes, I understand the basic physics since I am an electrical engineer and work in the automotive space, and I integrate batteries into battery electric vehicles.

    Regardless of your stance on warranties, corporate competition, or China… the original claim was “Seems like these batteries push more toward the speed and capacity side.”

    Where is the evidence to support this claim? For what reason could anyone think that BYD’s design philosophy caters to performance over durability? That is just pure fucken FUD.

    This happens all too often:

    • An engineering feat is achieved
    • A layman hops into the discussion to inform everyone about the concept of engineering tradeoffs (as if that is groundbreaking)
    • The layman gives their uninformed opinion about why they think the tradeoff was ill considered

    Here’s the simple truth: BYD’s entire battery design philosophy revolves around durability. If BYD was truly solely interested in battery density and charge speed, then why are they the primary champion of LFP batteries? If you were truly interested in performance and speed, LFP would be your last choice for battery chemistry. If anything, BYD leans more towards durability, safety, and longevity over performance - as is evidenced by their choice to make their entire design philosophy revolve around LFP. Teslas and Lucids lean towards Nickel Cobalt because Nickel Cobalt battery chemistry is fundamentally more performant than LFP batterys. THAT is “Basic Physics”.

    So, Who’s the Winner?

    The answer isn’t black and white. Both LFP and NMC batteries have their strengths and weaknesses. LFP batteries trade off some performance for greater safety and longevity, while NMC batteries offer higher performance at the expense of some safety and lifespan.

    The “winner” really depends on your specific needs. If you’re looking for high performance, especially in applications like EVs, NMC is likely your best bet. But if you prioritize longevity and safety—especially for DIY projects or energy storage—LFP batteries are the clear choice.

    In the end, whether you go with LFP or NMC, it’s all about matching the battery to your needs. For most everyday uses, especially in energy storage, LFP batteries are hard to beat for their combination of durability and safety.

    Do Publicly Owned, Planned Economies Work?

    Public transportation was efficient, extensive, and practically free. Subway fare was about eight cents in the 1970s, unchanged from the 1930s (Szymanski, 1984). Nothing comparable has ever existed in capitalist countries. This is because efficient, affordable and extensive public transportation would severely limit the profit-making opportunities of automobile manufacturers, petroleum companies, and civil engineering firms. In order to safeguard their profits, these firms use their wealth, connections and influence to stymie development of extensive, efficient and inexpensive public alternatives to private transportation. Governments, which need to keep private industry happy so that it continues to provide jobs, are constrained to play along. The only way to alter this is to bring capital under public control, in order to use it to meet public policy goals set out in a consciously constructed plan.

    The Soviet Union placed greater stress on healthcare than their capitalist competitors did. No other country had more physicians per capita or more hospital beds per capita than the USSR. In 1977, the Soviet Union had 35 doctors and 212 hospital beds per 10,000 compared to 18 doctors and 63 hospital beds in the United States (Szymanski, 1984). Most important, healthcare was free. That US citizens had to pay for their healthcare was considered extremely barbaric in the Soviet Union, and Soviet citizens “often questioned US tourists quite incredulously on this point” (Sherman, 1969).



  • Oh yeah our pot is a hoot and a half. You instantly feel like a cowboy when you break it out. Keeps the heat in for hours.

    It’s a simple Lodge cast iron pot we got from Bass Pro. They market it as a dutch oven, but without any area on top to stack coals, I’m skeptical of that description…

    This was a dispersed camping spot that is only accessible via dirt bike or SUV. Took about an hour of crawling over rocks in the 4runner to get there.
