  • You’re not getting past this bouncer

    Prompt

    ChatGPT came up with the punny name on its own:

    A large, heavy animal, resembling a buffalo, dressed as a bouncer at a cyberpunk-themed nightclub in an all-animal world. The club, named ‘Byte the Dust’, showcases a grungy, cyberpunk aesthetic, with a neon sign that’s bold and futuristic. The buffalo bouncer is wearing high-tech, neon-lit glasses and a distinctive cyberpunk mohawk. The outfit is a rugged, cybernetic ensemble with metallic accents. It stands imposingly at the club entrance, which features rough textures, rusted metal, and dimly lit neon lights. The buffalo’s expression is tough and unwavering, in harmony with the gritty cyberpunk theme. The artwork should be in a realistic style, highlighting the formidable presence of the buffalo and the intense, neon-tinged atmosphere of ‘Byte the Dust’.



  • The collect’s in the middle aren’t necessary, neither is splitting by ": ". Here’s a simpler version

    fn main() {
        let text = "seeds: 79 14 55 13\nwhatever";
        let seeds: Vec<_> = text
            .lines()
            .next()
            .unwrap()
            .split_whitespace()
            .skip(1)
            .map(|x| x.parse::<u32>().unwrap())
            .collect();
        println!("seeds: {:?}", seeds);
    }
    

    It is simpler to bang out a [int(num) for num in text.splitlines()[0].split(' ')[1:]] in Python, but that just shows the happy path with no error handling, and does a bunch of allocations that the Rust version doesn’t. You can also get slightly fancier in the Rust version by collecting into a Result for more succinct error handling if you’d like.

    EDIT: Here’s also a version using anyhow for error handling, and the aforementioned Result collecting:

    use anyhow::{anyhow, Result};
    
    fn main() -> Result<()> {
        let text = "seeds: 79 14 55 13\nwhatever";
        let seeds: Vec<u32> = text
            .lines()
            .next()
            .ok_or(anyhow!("No first line!"))?
            .split_whitespace()
            .skip(1)
            .map(str::parse)
            .collect::<Result<_, _>>()?;
        println!("seeds: {:?}", seeds);
        Ok(())
    }
    







  • You probably wouldn’t be committing this, unless you’re backing up a heavily WIP branch. The issue is that if you’re developing locally and need to make a temporary change, you might comment something out, which then requires commenting another now-unused variable, which then requires commenting out yet another variable, and so on. Go isn’t helping you here, it’s wasting your time for no good reason. Just emit a warning and allow CI to be configured to reject warnings.


  • That’s 👏 what 👏 CI 👏 is 👏 for

    Warn in dev, enforce stuff like this in CI and block PRs that don’t pass. Go is just being silly here, which is not surprising given that Rob Pike said

    Syntax highlighting is juvenile. When I was a child, I was taught arithmetic using colored rods. I grew up and today I use monochromatic numerals.

    The Go developers need to get over themselves.
