I was just recently going through some old episodes from Software Engineering Radio when I came across this one episode featuring Casey Muratori, where he goes through some of his thoughts around his video from February 2023, titled "‘Clean’ Code, Horrible Performance". I was actually already aware of the video by this time, but listening through the episode gave me an itch to see these concepts in my reality, experiment them by myself.

    Do you mean this for loop?

    for shape in &shapes {
  accum += shape.area();
}

    That does use an iterator

    for-in-loops, or to be more precise, iterator loops, are a simple syntactic sugar over a common practice within Rust, which is to loop over anything that implements IntoIterator until the iterator returned by .into_iter() returns None (or the loop body uses break).

      I think they meant using for accumulating, like this:

      shapes.iter().map(Shape::area).sum()

        Yes. That’s what I meant.

        Though I heavily expect the rust compiler to produce identical assembly for both types of iteration.

          Off-topic, but does that actually work? I would assume OpenAI would just ignore it and you’d have to prove that they did so.

            Dunno if it works. AI has been tricked into revealing it’s training data, so it’s possible that it happens and they are sued for using copyrighted material.

            This is my drop in the ocean.

                Welcome 🙂 A drop more.

                Btw, if you’re using linux and X11, you can bind a keyboard shortcut to the following shell-script (probably will need to install xte).

                #!/usr/bin/env bash
sleep 0.5
xte "str ::: spoiler Anti Commercial AI thingy"

                  I’m on Wayland, but I’m sure I can figure something out.

                  I do most of my lemmy-ing on mobile, so I’ll probably make a bot to auto-edit my posts or something.

                    Have fun! I’m curious how you’ll do it. If you figure out a way on Wayland, it would be great to read about it!
