    I had to double-take since in Python a common alternative to trick ? treat : notreat is (trick and treat) or notreat

    But I don’t think this translates to overlapping circles very well. “trick implies treat” is only defined inside the trick circle, outside is undefined if treat is true or not.

    I’m not going to draw a diagram, but here’s the “truth table” for A implies B:

    A, B, A -> B
    N, N, undefined
    N, Y, undefined
    Y, N, false
    Y, Y, true
    


  • I don’t think that matters, since when bruteforcimg a passphrase it’s more like using whole words as the characters (or tokens) in the password. If there’s 7776 possible unique words, it doesn’t matter what characters are in the words at all. Just how many password combinations are used.

    Side note, this is assuming words without character replacements. If you consider variations with A->@ or B->8 there ends up being significantly more possible unique “words”

    I think we have a fundamental disagreement on what counts as science, and that’s okay.

    Your methodology seems to imply a valid scientific experiment must be sufficiently rigorous as to improve on the current scientific consensus. And I do partially agree, it’s a waste of time collecting data that’s just going to be worse than previously collected, more controlled experiments.

    By my philosophy is a lot looser. To quote Adam Savage: “The only difference between screwing around and science, is writing it down”

    People don’t use Kelvin when referring to seasons. Sure, there’s plenty of ambiguity if someone says it’s 32° out without specifying the units, and you can infer from context, but that has nothing to do with Kelvin starting at absolute zero. Saying “degrees” immediately rules out Kelvin as a unit.

    I’m explicitly arguing that you can separate the two. I can perform a completely independent experiment in my house.
    For example:

    • I make a hypothesis that my stove can boil 1L of water in 10 minutes.
    • I then measure how long my stove takes to boil that water.
    • I can then record these results to inform my future cooking and water boiling experiments.
    • Proper use of the scientific method may also attempt to measure atmospheric pressure, water contaminants, and other factors that may affect the result.

    I don’t have to publish the results anywhere or even talk with another person, yet I’ve still used the scientific method. I’m not a professional scientist, but I am an amateur one.

    I’d agree for the result to be useful to society, the science should be published. But science can still be useful to an individual without sharing. I use the scientific method regularly in my daily life for mundane things, and often it’s just not worth the time to communicate to others because the situation is unique to me. I write it down for myself later, which doesn’t make the science any less valid.

    I’d argue the scientific method does not have to include multiple people at all. All it is, is the process of coming up with a hypothesis, designing an experiment to check that hypothesis, and then repeating while trying to control for external factors (like your own personal bias). You can absolutely do science on your own.

    The broader field of academia and getting scientific papers published is more of a governance thing than science. You can come up with better hypotheses by reviewing other people’s science, but that doesn’t mean when a flat earther ignores all current consensus and does their own tests that it isn’t still science.



  • If you look at how Gorillas kind of walk around on their fists, it definitely makes sense that there’s some evolutionary benefit to the knuckle shape. It doesn’t have to be related to hitting things either. It’s easiest to support yourself with a straight wrist, like if you’re holding a branch, vs putting your palm flat is a lot more stress on your wrist.


  • Fuck farming. It’s a dirty industry.

    That’s kind of a wild takeaway… Personally I like not having to grow my own food. And a huge amount of efficiency is gained with large scale farming compared to small farms or personal growing.

    Unsustainable subsidies aren’t okay, and we should strive for more environmentally friendly farms, but farming itself is not one of our problems.

    The first computers took up entire rooms and they could only do about as much as a calculator. There was a point in time that having a computer do multiplication and long division for you saved you hours of time because the alternative was have 2 or 3 people do it by hand and then compare to check for mistakes.

    Some of the code cracking computers used for breaking war-time ciphers were state of the art, and their only job was to check as many combinations as possible, way faster than any human could. Which left the actual scientists to find optimizations and analyze any results.



  • Honestly the best thing about FOSS is that money isn’t driving all the decisions. Most open-source projects are built because the dev just wants to build something cool or useful, or they’re trying to solve specific problems. Most individual devs don’t really care if their user count goes up every quarter.
    Personally I’ve been maintaining a chrome extension for about 10 years, and it’s sat happily with about 7000 users that entire time. I built it because I wanted to use it, and I’ve declined several offers to buy the extension and monetize it.
