  • Having seen firsthand what happens when someone unknowingly enters a hypoxic enclosed space, I think the difference is foreknowledge. Thrashing sounds like acidosis from holding one’s breath. I was helping an acquaintance work on his old steel boat. There was a watertight compartment. The risk of steel-enclosed spaces is that rusty steel in an enclosed space can consume all of the oxygen, leaving only nitrogen rich air.

    He opened the hatch and, before I could stop him, he just strode on in like it was nothing. He was unconscious before I could get to him, maybe ten seconds. Fortunately, he was near enough to the hatch that I could just reach in and grab him, rather than trying to find an air tank and regulator, and then put it on.

    He recovered just fine, but had a terrible headache. He didn’t remember anything about it. He didn’t thrash. There was no drama. He walked in and fell unconscious. Lucky for him it was a small space, so the bulkheads kept him from doing a full header into the steel deck.




  • You are confidently incorrect on this. Currency == money. Money is, for we hoi polloi, a barely consentual conversion and exchange system for our labor, hypothetically allowing us to convert our labor into readily fungible exchange units. Money, at the Capital Class level, is debt, and therefore control, i.e. power. Money is just how they keep score.

    There are plenty of barter gifting and Communist (“from those of ability to those of need”) economies, just on scales that fly below the radar of most economists. Your sweeping assertion leads me to believe that you may simply be ignorant of those non-monetary exchanges. Would you be willing to add more context to your assertion?

    Edit: I misspoke; crashfrog raises a valid point, and I meant gift economies.



  • Wampum was used by Eastern Costal tribes as a storytelling aid.

    In the Salish Tribes, dentalium shell necklaces were used as a status symbol/indication of social rank. Some tribes used the necklaces as a type of currency, but I’ve only heard the “some tribes did this” part; never anything about which specific tribes used dentalium as currency.

    Obviously, anything that holds perceived value can be traded.

    Source: went to junior high in a school that taught two full years of Haudenosaunee (also called Iroquois) history.

    Salish source: I’ve been a volunteer naturalist in the Puget Sound for eight years with an annual training requirement, with entire days allocated to history of the original Salish tribe for the area where we’re working.








  • I see a lot of specific examples, but here is a good engineering guideline: do not skimp on physical interfaces. **Anywhere energy is changing form or if it touches your body, don’t skimp on those. **

    For example

    • tires
    • bicycle saddle
    • heaters/furnaces
    • electrical inverters
    • keyboard
    • mouse
    • engines
    • shoes
    • eyewear
    • clothes (buy used if necessary, but always buy quality clothing)

    Quality usually means more money, but sometimes one is able to find a high quality and low-cost version. In my experience though, trying to find the cheap version that works well means trying so many permutations; it would have been more economical to just get the more costly version in the first place.





  • I wonder how much of a role palate refinement is for this trend. For example: Starbucks, for as terrible as their coffee is, did a lot to elevate the overall regard of coffee; bean juice was no longer just a bitter stew we tolerated to get our caffeine fix. Starbucks broke trail for craft coffee roasting more general popularity.

    Could it be the same with alcoholic beverages? I used to think Maker’s Mark was the best bourbon going. Now I know better, but so many of the craft bourbons are expensive or just plain hard to find. Ditto for my favorite hazy IPAs. Why binge drink the good stuff when your palate is going to be wrecked after three beers? And since I’m not going to drink swill, welp, guess I’m not going to get drunk tonight!
