Do Apple's chips (M1 etc) change this at all, since they share memory with the GPU?

You know nothing of what I'm programming. You don't know when, whether, or how my program accesses or deletes data. You don't know what domain I'm in, whether I'm on a team, or wha…

GP was confused about why the doubly linked list case was so important, so I enlightened, it's an example of an entire class of the borrow checker's problems. Your response isn't r…

It's not just doubly linked lists. They're just a basic example of borrow checking not being able to handle a lot of easy patterns that are perfectly safe in other languages.

I've experienced this as well. Any disagreement always comes down to "you just haven't used it enough". I let myself take that gaslighting for years before I decided to just not go…

Single ownership often introduces bugs of its own. In Java, I never need to create an Err if the thing my ID is "pointing" to isn't around anymore in whatever hash map the borrow c…

Pony is a great example of fearless concurrency without the borrow checker's difficulties.

That absolute claim is simply not true. That's like saying that people need to avoid shared mutability in every program, which simply doesn't make sense for a lot of programs, espe…

Easier than C or C++ for sure. But I definitely wouldn't say that Rust as easy as a GC'd language like Java or Go. They have strictly less constraints to deal with, they can let yo…

Can we please not do this? It's fine to give a different viewpoint, but it's surprisingly common that whenever someone says anything bad about Rust, a Rust user comes in to say tha…

I'm sometimes a bit confused when people say that Rust has less cognitive load. I assume that's compared to something like C or C++, right? I've used Rust and (imperative-style) Sc…

Rust will never be used as widely as GC'd languages like Java, Go, C#, etc. It's incredibly well-designed, but you can't design away the inherent complexity of writing safe, secure…

I've seen both sides of this, as a Rust user and as a Go user. Rust users are generally friendly to one another, and to people who are interested in Rust. Hoever, some Rust users a…

For a single player turn-based game, I'm not so sure the tradeoff is as obvious as everyone says, after coding one in C++ and another in Rust. It's turn based, so I don't need AAA …

Saying it's "idiomatic" isn't very actionable advice for people, the average programmer hears that and doesn't really know when to use Rc over other approaches. I also wouldn't say…

That's where the discipline comes in: one has to know when it's okay to use the simpler approach (indices into a Vec), and when it's better to use Arcs such as to prevent privacy p…

In Rust, people tend to go for the easiest solution that works within the borrow checker, and not workarounds like Rc or Arc. Otherwise, the performance hit means there's little re…

That's why I said one should have the discipline and practices in place to avoid this bug. I think we can do better than saying that indexes into Vecs are "non-idiomatic" in applic…

That's why I mentioned one needs to have discipline, to not use that particular solution. We agree it's not the best solution. And it's easy for us to say that now, after I've spel…

In fact, in the pursuit of eliminating memory-safety and security bugs, Rust can sometimes makes some privacy bugs more likely. For example, in GC'd/RC'd languages, if we have seve…

React and Polymer seemed like an okay balance of of OO and functional... are our current GUI architectures really that nasty?

The author could have recommended Scala, which has all of Rust's type system benefits, plus garbage collection (and of course, minus the low level control over performance). YMMV t…

I'm also curious about the architectural consequences of Rust. It seems to force us into a very procedural or functional style, and sometimes makes us use parallel collections for …

Something about Odin I like is that you can have multiple allocators, and use a bump allocator for just a specific call (and its subcalls), and afterward free it all at once, and g…

Doesn't GhostCell preclude deletion, and effectively grow forever?
