    The asphalt pavement of roads must be 4 inches thick to last forever. 3 inches lasts 5 years, 2 inches lasts one year, 1 inch is crumbling before you finish. You constantly see crumbling roads in the third world because of corruption, they don’t put as much pavement down as they charge for.

    Mechanisms are technical. And the fact that some will claim this isn’t a fact is actively obscuring it.

      It’s just helpful as in the picture, TBH.

      Which capitalism? If you don’t specify what you mean, you sound like you’re selling something. And if you do, capitalism might be an extra word you don’t need.

        What’s being poured is the phrase “the problem is capitalism” which, in your description, would be the “helpful” salad dressing.

        And to answer your question, capitalism.

        The one in which the foundation is to grow capital which inherently means there must be devaluation or exploitation within a system to accrue an “excess” of capital.

        The one that by its very mechanisms introduces a class strata based on hierarchy and inherently aligns itself to those who would.so division, entrenching the classes of the “haves” and the “have nots” appealing to the selfish nature of humanity and reinforcing other forms of “hierarchy” such as racial divides. (Aka, racism, if it would ever be solved, will never happen under capitalism.)

        The one by which it exists in any form such that it aligns with the baser instincts of human selfishness and greed and will inherently reward those of narcissistic or unempathetic tendencies more as they are most willing to exploit both the planet and other humans.

        The one that no matter how it is implemented, following its foundational principle of the “freedom to grow capital,” that will seek to remove any guardrails or regulations put in place to limit it as those limit the growth of capital.

        That one. That capitalism. The only one.

    There’s no way to make a backdoor for encryption that keeps the encryption secure. Politicians and government flunkies can’t seem to wrap their pea brains around that concept.

    The longevity of concrete isn’t just tied to the cylinder break strength.

    Also, concrete with certain aggregates end up creating silica gel, which is bad for concrete.

    In german and english, the comma in numbers is swapped. So the number 123.45 in german would be written as 123,45 while ironically, the thing that we used to separate thousands from hundreds is also swapped. So one-thousand-four-hundred would be written as 1,400 in english but as 1.400 in german …

      There are many European mechanisms that make more sense to me, like aluminum being “alumINIUM”, as with many other elements.

      But periods in the middle of numbers always felt wrong to me. We already have structures for sentences that pause, then eventually close a thought: “Billy played with Susie, and her dog. Cute!” Not “Billy played with Susie. and her dog, Cute!”

      On top of that, you would pronounce 678 as six-hundred-seven-ty-eight in english … guess what it is in german:

      Sechs-hundert-acht-und-sieb-zig (literally six-hundred-eight-and-seven-ty)


      i’m actually trying to change this point specifically because it irks me … but i am sadly alone with it.

    Hundreds of years of burning coal has spread mercury compounds all over the land, so that quite often when they build a new dam for hydroelectric power it’s dissolved into the water and ends up concentrated in fishes that people eat.

    The “magical formula” for stairs.

    If this rule isn’t followed when building stairs, then it feels uncomfortable and more accidents will actually happen there.

    In easy terms, it says: 2x riser + tread = average step lenght, usually 63cm.

      I’m curious how this compares to eras before this formula was normalized and if this is universal or more so just a matter of keeping things the same so people get used to them.

        I know of a few cases in religious buildings where stairs were designed to have a mystical effect. In Angkor Wat, for example, the stairs have a steep and tall tread pattern. Commoners weren’t used to them so they’d be exhausted, but the local monks were used to them so they could ascend and descend with ease.

        Visit any old city in the UK (York and Edinburgh for example) and a lot of passages between streets have steps with uneven heights.

        When you’re expecting it, its fine, you take extra care. But when its a modern building and they’ve fucked it up you really notice

            New England. When I was looking at houses I went in a few of these as that’s basically a lot of the market here, and most of them had at least one set of stairs I found myself uncomfortable on. Mine aren’t too bad, just narrow and short, but I’m short so it doesn’t bother me really. The attic is the weird one because it’s this set of spiral wooden stairs that leads into a really nice, large, fully finished attic. It could absolutely be another useful space…except…the stairs start out in a bedroom closet.

          Same here. My stairs seemed to be an afterthought meant to squeeze in where it shouldn’t, built by someone who shouldn’t even been allowed to hold a hammer. I have size 13 feet, they hang several inches over the step when I use them. I’ve went down those stairs faster than intended a few times now. The basement stairs were even worse, but they’ve been replaced now.

              Ya old houses can be… interesting to say the least lol! The last person that owned this place died on the living room floor about 4 feet where I’m sitting right now. Bonus is I got new flooring out of the deal.

              I’m actually slightly surprised it wasn’t the stairs that finished him off.

        I guess in China the number is smaller because the average people are smaller. Otherwise it is universal. It has been found out, not made up arbitrarily.

      DNS constantly has weird little issues and attacks, same with ARP. Meanwhile, BGP just keeps on chugging along in the background, ignored and unappreciated, day in and day out.

        Despite the many issues that it can cause, that is an important feature of BGP. Since network connections can be asymmetrical, and outbound and inbound connections can have different requirements, the best (or most adequate) route from A to B might not be the best route from B to A.

      Yeah. The worst part is that a lot of engineers and technicians don’t fully understand galvanic corrosion when specifying how to attach two different metals together.
