    I’m not sure why witx’s comment was downvoted. This is absolutely the standard usage in math and computer science.

    Yes. I’m not sure how slow it is in Julia, but pure functional languages do tend to generate more garbage for this reason. Hopefully the compiler can optimize it away in simple cas…

    I think we’re talking past each other. Lenses serve many purposes. All I’m saying is that in practice, the most common role they fulfil is to act as a counterpart for mutable refer…

    Yeah, but I’m saying that in 90% of the cases where a functional program would use lenses, the corresponding imperative program would just use references.

    > Your natural choice in the "OOP style" is to write a lot of boiler plate to point to each different field you want to get/set. Your natural alternative to lenses in imperative la…

    Immutability gives you persistence, which can be practically useful. It’s not just fear.

    Yeah, sorry, I realized after I commented.

    But what’s the benefit of this approach? It seems needlessly expensive, both in terms of computational overhead (walking up and down the state tree) and how much more code it requi…

    You know, I do not actually know that a website had ads before clicking on a link to it; I would be happy to only visit websites without ads. It’s scummy to shove ads in my face wi…

    Imagine asking the browser on my hardware to do things I don’t want it to do, and acting shocked when I tell it not to.

    Can you point me to one of these reviews of case reports? As it is, your reply is too vague to be helpful.

    How much do advertisers pay per customer, and where can I find this analysis?

    It’s not a completely arbitrary framing. It’s a consequence of other beliefs (ethical beliefs, beliefs about what you can or should tolerate, etc.), which are ultimately arbitrary,…

    I’m sorry Lifeline did that to you. I believe that if society actually wants people to open up about their problems and seek help, it can’t pull this sort of shit on them.

    If you accept that “the world and life aren’t particularly pleasant things”, why do you want to prevent suicide?

    Agreed - blue noise dithering is very commonly used in computer graphics because it’s cheap and great, but it might be worth mentioning that it’s a kind of ordered dithering, which…

    Sometimes repetition serves a purpose, and sometimes it doesn’t.
