From a security perspective, yes Rust is better, but it's still a security issue: if you can make a Rust program panic due to overflow, that's a DoS attack. I think this description is a very narrow way to look at memory safety (a

I wrote a longer response to a sibling comment, but I highly dispute this: > Rust's array type is an actual array, and so a lot of the problems you're worried about (which would be big pitfalls out of the box in C) only happen

I would say that this is an extremely narrow view of "memory safety", and totally ignores the broader concept of "lifetime safety". Yes, if the thing you want to prevent is crashes due to segfaults, indexes in Rust preve

I’ve always thought this is a pretty big blindspot in Rust. Having a raw pointer and having an index into an array are essentially equivalent, and doing this in Rust is a way to turn off the borrow checker for this particular object. The in

The common thread in both cases is (as you say) children: in both creoles and NSL, the early versions of the language are somewhat primitive (being developed by older children and adults), but when children are exposed to it from an early a

The classic example which I think you’re referring to is Nicaraguan Sign Language, which developed organically in Nicaraguan schools for deaf children where neither the children nor the teachers knew any other form of sign language. It’s a

Indeed, there were a lot of scaremongering about covid. It then turned into the worst global pandemic in a century which killed millions and millions of people, and hundreds of millions of people (if not billions) was afflicted with it, man

For sure. I didn't mean to imply otherwise. I was just saying I'm always curious about what the processes are in companies that lead to these disastrous results.

I always wonder about stories like this what the internal process that lead to this insane overreaction was. At some point, did someone really make the decision "lets send Pinkertons to this guy's house, risking an enormous public

Assuming low or no contention, it is easy to imagine a scenario where a mutex vastly outperforms it: if you need to push a 1000 things into the queue, it's still just two fences for the mutex but it's now a 1000 CASes. Moreover: t

If it's this common, it should be straight-forward to test as well, right? Allocate 1 gig of memory, do whatever mmap call you need to make sure it's not paged out, fill it with deterministically random stuff, then every hour chec

Pretty excellent summary, this is roughly the taxonomy I have in my head. I would maybe add SQL as an ur-language as well. It's not quite general purpose like most of these, but it should have a place in this list, I think. It has some

That's really interesting, I hadn't considered the case of the compiler caching the address of errno. Obviously it can't cache the value across a function call (with or without a yield point), but caching the address does m

Do you have any specific reason to say why it will cause miscompilation? Anything in particular that makes this UB? My understanding is that as long as your functions compile to the correct ABI, it shouldn't be a problem. All you'

Yeah, but they don't have to make it worse ! If they do the right thing here and transfer the licenses somehow, it's way more likely that whatever their next thing is is going to go down smoother. If they don't do the right

Played Cyberpunk on Stadia as well, mostly just to try the service out. Not a bad experience, honestly. Stadia had the technical stuff pretty nailed from day 1. It was just the business model that was out of whack.

What about texts where there are more or less “canonical” illustrations? Like, for an edition of Bleak House by Charles Dickens, it’s just not the same without the sketches by “Phiz” that were present in the original publication. Same with

How would you suggest the kernel would accomplish that feat? If the user calls read() on a file descriptor, what can the kernel do except... you know... actually read from it and copy the data to user space?
