  • I don’t see how what conservatives say has to do with reality.

    Biden has been “senile” and “too old” for years now, during which time we’ve had a functioning Biden administration.

    The Trump admin was limp, chronically understaffed, weak, ineffectual. That’s what they’re pretending is better than Biden. Conservatives don’t even care about senility so if you hear them rag on Biden and think they’re right, you’re not understanding what they’re really saying.






  • It’s new to me, I think it’s saying that your system is built up by you declaring what you want in a file, a single source that everything comes from.

    It’s atomic because each action the system takes is carefully completed rather than bailing out and requiring you to fix something.

    It’s immutable meaning you declare how you want things to be set up and then critical changes stem from those declarations and nothing else. You would obviously generate preferences, save data, etc. but the files that make the system / packages work are carefully locked.

    It’s like the concept of flatpaks + structured system defining + modern common sense OS operations?





  • You use lifetimes to annotate parameters and return values in order to tell the compiler about how long things must last for your function to be valid. You can link a specific input with the output, or explicitly separate them. If you don’t give lifetimes the language uses some basic rules to do it for you. If it can’t, eg it’s ambiguous, then it’s a compile error and you need to do it manually.

    It’s one of the harder concepts of rust to explain succinctly. But imagine you had a function that took strA and strB, used strB to find a subsection of strA, and then return a slice of strA. That slice is tied to strA. You would use 'a annotation for strA and the return value, and 'b for strB.

    Rust compiler will detect the lifetime being shorter than expected.


    Also, ownership semantics. Think c++ move semantics. Only one person is left with a good value, the previous owners just have garbage data they can’t use anymore. If you created a thing on the heap and then gave it away, you wouldn’t have it anymore to free at the end. If you want to have “multiple owners” then you need ref counting and such, which also stops this problem of premature freeing.


    Edit: one more thing: reference rules. You can have many read-only references to a thing, or one mutable reference. Unless you’re doing crazy things, the compiler simply won’t let you have references to a thing, and then via one of those references free that thing, thereby invalidating the other references.




  • But capitalism doesn’t explain itself in terms of “the owning class” screwing everything up out of self-interest. Capitalism will talk about positively channeling people’s self-interest. The intent is to construct a system that benefits people the most.

    It’s objectively not working as intended unless you think there’s like… a hidden conspiracy behind capitalism where the elites carefully inculcated an economic theory over generations in order to normalize a system that would end up solidifying their status for hundreds of years to come.

    It’s not working as intended, and it won’t work as intended, therefore we shouldn’t try to fix it.







  • On one hand, the point of Goku is that he isn’t a good person, he’s more like a force of nature. A lot of things he does isn’t good by normal measures.

    On the other hand, he’s a messiah figure. He is the savior of earth, a god, and his actions have worked out so far. If it’s bad but Goku does it and nobody can change his mind, then it’s good.


  • When a computer reads some signal, the 0s and 1s in it’s memory is the data. The data must be processed so that the computer can understand it.

    This computer is using threads to read neuron activity. It must necessarily receive data because if it didn’t it wouldn’t be reading neuron activity. They’re the same thing.

    This data is processed so that the computer can make sense of the brain. Once it understands some activity it generates signals that can control external devices.

    Here’s an example. Imagine a device that monitors the heart and does something to fix a problem. The device would get data on the heart and process the data so that it can perform it’s function.

    Wouldn’t monitoring health concerns and mitigating data loss be extremely important in these scenarios?
