Of all the strengths that Java and C have, I would not call syntax one of them. :) So this title seems quite strange. Not the sales pitch I would make. It is understandable though, considering this language is 30+ years old. Probably not th

I think the current plan is to integrate never-panic into the upcoming effect system (formerly keyword generics), along with const and async. So all these function annotations can share the same behavior and syntax, and higher order functio

Neither of those gives memory safety, which is what the parent comment is about. If you release the temporary allocator while a pointer to some data is live, you get use after free. If you defer freeing a resource, and a pointer to the reso

Level 4 / total programming languages are not turing complete. Because you can't simulate every turing machine in them, only some subset that provably halts. (And because the halting problem is undecidable, there will always be so

The solution is to ask the OS to detect it for you. Linux offers a syscall for this (riscv_hwprobe). Has the drawback that it requires OS support, of course. But RVV requires OS support anyway (e.g. managing mstatus, saving vector registers

Read-only parameters should be contravariant, write-only parameters should be covariant, and read-write parameters should be invariant.

Is there any place that actually sells the Musebook for that price? I was only able to find articles about it being "available for pre-order at $299.00", and one Aliexpress seller who wants 740,69€.

3 hex digits = 12 bits = 4096 entries, the size of each address translation table on ARM. So it does make some (twisted) sort of sense. Assuming you're using 4k page size

I don't know what to tell you, there are just multiple ways to use the same words. What Rust calls enums are called tagged unions in most other languages. Enum usually refers to a simple collection of named values, what Rust calls fiel

My best guess is they're referring to writing functions that initialize something using an "out" parameter in Hylo, which would be equivalent to a "&mut MaybeUninit<...>" parameter in Rust.

> Golang has even better memory safety guarantees than Rust I don't think that's true at all. For one, Go has data races, which lead to undefined behavior and memory corruption. For example, appending to the same slice from mul

FLT_EPSILON is not 0.01, it's 0.00000011920929. But it's impossible to have a number that's 0.00000011920929 less than 5.0, or 0.00000011920929 more than 5.0, because the floats with enough magnitude to represent 5 are spaced

If the numbers you are comparing are greater than 2, abs(a - b) < FLT_EPSILON is equivalent to a == b. Because it's not possible for two large numbers to not be equal, but also closer together than FLT_EPSILON.

This code is incorrect, but I don't blame them. :) Probably one of the most common float-related mistakes, even among people who "know how floats work". FLT_EPSILON is the difference between 1.0 and the next larger float. It&

I don't know of any Unix that allows forward slashes in file names. On macOS you can use : which is displayed as / in Finder, but in exchange you can't put a : in file names...
