> It's ~100x times slower than hardware floating-point because of using arbitrary-precision floating-point numbers implemented entirely in software. Thanks for the numbers, how did you get that estimate? Did you consider SIMD?

You could always just return nan in that case, like for normal arithmetic.

Arb depends on lots of other numerical libraries (namely FLINT, MPFR and GMP or MPIR). If you want pure-Rust alternatives, the ecosystem is just not there yet.

You seem to be assuming no one else found and exploited the vulnerability in the meantime.

They compared a browser with ad blocking with one without it. Of course it's faster not to load ads.

How can you show convergence when it is not shown that there is a unique solution to Navier-Stokes?

Your assumption is wrong. I fear that articles like this are partially responsible for that.

They have a feature where you can invite people to the group with a link that requires the server being able to add people. Isn't that a fairly obvious motive?

Nobody knows how to store it in good conditions. The attempts in Germany are highly controversial.

There is certainly a cost, I'm just not sure I would call it abstraction cost. Is memory safety an abstraction? Safe Rust has runtime costs as well (mostly bound checks).

Well, unsafe Rust does tend to look like this. You were claiming that it is only for interfacing with C code, but unsafe is also used for performance, as in the snippet above. You were IMHO incorrectly dismissing the parent comment based on

There are already FP features and monads in Rust. What exactly do you want? It is unlikely you will ever see non-zero cost abstractions in idiomatic Rust.

Your comment is misleading. The code in question is inside a function of the signature extract_last_path_segment(&str, &str) This is pure Rust, no C interface involved.

Of course, because in STEM it's the opposite: an oversupply of (educated) men.

Thanks for the links! In addition to the yet unsolved waste disposal problem you mentioned, there is the problem of mining the nuclear fuel. This can be quite dangerous to the miners, especially in countries with lax security standards. I w
