  • Well, a lot of stock trading isn’t as simple as just stock picking, buying and selling individual stocks.

    Much of the market is made up of derivatives trading, such as options, where you aren’t trading the stock itself, instead you are trading the option to buy the stock.

    The value of the option is derived from the value of the underlying asset, but it is not absolutely coupled to it (this is how a lot of the money is made, by finding market inefficiencies and capitalizing on things like slippage, where there is a mismatch in the value of the derivative and it’s underlying)

    What the person above is saying is that, when it becomes no longer profitable to trade underlying assets directly, new derivative markets will be invented that trade around other underlying assets.

    Think about unregulated Bitcoin trading for example, while contrived, imagine a crypto currency that is coupled with the price of another asset (these exist, like USDcoin) such as a stock, future, option, or something else.

    I should add, typically the derivative kind of collapse into the underlying at some point, but in the case of an option, it might be traded 100 times before that happens, during each of those trades the actual asset (e.g. the underlying stock) doesn’t actually change possession, and a given side of the contract may or may not be changing possession. If you write a call option for a 100 shares of Ford you own, you aren’t selling the stock unless the actual call gets assigned and you are required to fulfill the contract, but the ‘buyer’ side of the contract could have been sold 100 times in the meantime.

    All this to say, it’s complicated and there are lots of opportunities for shady shit to happen.








  • Trash disposal isn’t free, yea the dog poop is probably a negligent amount, but most people have to explicitly pay for trash disposal, and so filling up other people’s trash cans can either cause an additional financial burden on them, or mean that they can’t effectively dispose of all of their trash.

    It looks like in your case, each unit gets a can assigned to it, and service fees and replacements cost the individual directly, additionally, there are fines for trash violations, so having other people put unknown trash in your bins can result in a direct financial burden. I think it’s pretty reasonable to be relatively protective over your trash bin if you are the one that has to pay for service, replacements, and fees.









  • No it’s not at all.

    It’s literally an aluminum sheet, it will slice your hand open.

    One of the most common uses is when you remove something like a fairing or a panel, to access something else, when you put the panel back on there are gaps between them. They are not structural, but it does hurt the aerodynamics of the plane, affecting the fuel mileage and cosmetics.

    The solution is sealant in the panel gaps, this helps prevent moisture from seeping, and improves aerodynamics.

    The issue is that the sealant takes a long time to cure properly, and when it isn’t fully cured, it will splatter everywhere (I’ve seen this happen). A common scenario as an example is, putting the final panels back on after an inspection, it’s nighttime in the winter, the sealant isn’t curing, instead of the plane sitting idle for 48 hours while sealant cures, you can just put speed tape over it, the tape holds the sealant in place while it cures and then mechanics can take the tape of after it’s fully cured.
