Hello everyone, I’ve followed this thread yesterday and noticed a few very negative reactions towards the choice of Java. I follow Java evolution from far away, but it seemed like it was evolving in a good direction since the last few years, and that performance-wise it would make sense for the back-end of a Lemmy-like platform.

Is it indeed the case? I was just curious to see that much negativity towards one of the most popular languages.

    So…you had to make your own version of unique_ptr to make it zero-cost? Doesn’t that just confirm the original statement you were disagreeing with, that unique_ptr has a small runtime cost? Or was there some other reason you thought the creator of the video you shared has “no idea” what unique_ptr is?

    I also don’t understand why the standard library can’t use the trivial-abi attribute. Different implementations of the standard library aren’t required to be interoperable, are they?

    I still don’t understand what you think is “apples-to-oranges” here. If you change the Rust code to require the C ABI, there’s no difference in the generated code: https://godbolt.org/z/1xf9qG3n8
