Who reads this anyway? Nobody, that’s who. I could write just about anything here, and it wouldn’t make a difference. As a matter of fact, I’m kinda curious to find out how much text can you dump in here. If you’re like really verbose, you could go on and on about any pointless…[no more than this]

  • I’m out of the loop, so what’s the big deal with this? What kind of promise does that break?

    If he wants to keep American companies in American hands, isn’t this exactly the kind of thing he should be doing? Still probably not the smartest thing to do but, isn’t this kind of period of isolationism exactly what he has promised.

    On the other hand, I recall hearing something about him protecting American jobs, but these two goals are in conflict here. Either you fund your industry yourself or accept foreign investments. If the former isn’t possible, then the latter remains the obvious choice.












  • Our current “forcefields” are super picky. They refuse to work with anything other than that one thing they were specifically designed for and the list of options is very short.

    If you want to deflect things with a magnetic or electric charge, we already have the right kind of “forcefield” for that. However, it’s not exactly the kind of shell you put around a space ship to keep it protected, so even in this limited sense we still have a long way to go. The magnetic field of the Earth directs some of the incoming particles to the poles, which isn’t really ideal if your goal is to deflect all incoming fire.

    If you want to protect the ship/planet from physical projectiles, we have no forcefields at all. That sort of stuff is just pure sci-fi at the moment.



  • I’ve once had a password that was over 200 characters long. That was in a custom email server where the admin either didn’t know or care about limitations. I mean, if you can have a super long password, then why not. I just kept on going until I felt like it was secure enough.

    I used a randomly generated character soup, so there’s no way I’m ever going to memorize that nightmare of a password. Even if I print it on paper and hand to you, there’s a pretty good chance that you wouldn’t be able to type it correctly without restoring to OCR.


  • That’s roughly how open pit mining works. In some mines, you start with a pit, but later make a mine shaft if you need to go even deeper.

    A pit is relatively cheap to start with, but it becomes more expensive as you go deeper. Eventually, a traditional mine shaft becomes cheaper than continuing with a pit.

    If you have a ridiculously deep mine shaft, you begin to run into various problems like walls collapsing and the temperature increasing. There can also be lots of water you need to pump out constantly.

    Eventually, the shaft becomes so deep and the problem so large, that continuing becomes a nightmare. That’s why even the deepest mines aren’t really that deep considering how thick the tectonic plates are.





  • With many chemicals, we just don’t know.

    Usually, it’s pretty easy to run some tests to find what it takes to kill 50% of the test mice (LD50), but that value will only give you a very rough estimate, because toxicology is hard. Besides, you’re not really trying to just prevent 50% humans from getting killed. You don’t want people to get sick either.

    Many chemicals also have limits that are considered safe in an occupational exposure setting. If it says that you can safely be exposed to a specific concentration for 8 hours, it’s not the same as having that same chemical in your food for 20 years.

    Studying acute toxicity and mortality is much easier than studying chronic toxicity and illness. We also tend to use mice instead of humans in these tests, which opens another can of worms. Figuring out what’s safe for you to eat for the rest of your life is just next level stuff, which is why we usually don’t know how much is still safe.
