It's a little unclear, but it's a live updating number, if you follow the directions, you'll see the second number decrease.

I don't think so, "while vacant" is an infinite amount of time, if you look infinitely far into the future.

"Participants got behind the wheel of a driving simulator equipped with everything you’d find in a real car – from the steering wheel to the pedals and dashboard. A large touchscre…

To be even fair-er, it wasn't actually memory unsafety, it was "just" unsoundness, there was a type, that IF you gave it an io reader implementation that was weird, that implementa…

Thats kinda the problem, there are concepts in rust that don't have equivalents in other common languages. In this case, rust's type system models data-race-safety: it prevents dat…

Rust has access control. Fields are private by default.

Wow the comments are.. Bad. Not all single instruction operations are the same.

"The common ground is that I have absolutely no interest in helping to spread a multi-language code base. I absolutely support using Rust in new codebase, but I do not at all in Li…

Inspired by onemillioncheckboxes.com, I made my own version, where everyone shares 1 million sliders, setting one to a value sets it for everyone.

Hi, I think even the remaining benchmark isn't showing what you're trying to show: https://rust.godbolt.org/z/r9rP6xohb Rust realizes the vector is never used, and so never does an…

Rust optimizes factorial to be iterative, not using recursion (tail or otherwise) at all, and it turns `factorial(15, 1)` into `1307674368000`: https://rust.godbolt.org/z/bGrWfYKrP…

Honestly feels like a very, very different use case from utf8-ish strings, at a quick read?

For simple cases, I'll do that, but for longer commands, I've taken to doing rc=0 long command || rc = $? if (( rc == 0 ))...

Literally every file operation HAS to go through the kernel. This is implementing "what does it mean to read/write this special device file"

I believe they're asking for "this function returns a function of the same type (Fn/FnMut/FnOnce) as its first argument, but with different arguments. A generic way to write someth…

Yes it does exactly that. It returns an iterator over the removed items, but when that iterator is dropped, it modifies the collection. See https://play.rust-lang.org/?version=stab…

And for move to front, why not `a[..i+1].rotate_right(1);`, rather than moving to the back and then shifting everything?

Expand does actually exist in the standard library, but it's a bit of a strange incantation... vec.splice(i..i, std::iter::repeat(0).take(length)); This replaces the values in rang…

_Implementing_ a variadic function in rust requires nightly. I'm guessing that's what they meant. Calling one has been available for forever.

I would absolutely support something to replace ( ( ( ( a).b).c).d).e with a->b->c->d->e, regardless of how much code had been written without that feature. Do you not like the arr…

Of course. There should never be more than one way to do something in c, even if it makes things easier or less error prone. This is why the -> operator would never be included in …

Because there is no UB in the original program. It constructs a pointer to the "one past the end" element, but that is fine, and the original program never dereferences that pointe…

Your block of code can be (and absolutely is) optimized to output zero directly (in c, because the assembly is easier to read): https://c.godbolt.org/z/qe3f4K `*(&i+1)` dereference…
