Yes. But I like that rust gives you the option. In C, the only way to write a monomorphized hash table or array list involves horribly ugly macros that are difficult to write and debug. Rust does monomorphization by default, but you can als

> Rust can implement doubly linked list in safe code. It can. It wraps the unsafe parts in an abstract manner. As far as I know, only with Rc / RefCell. But that has a significant performance cost. Am I wrong? I'd love to see a

Davinci Resolve is free. At least, for the non studio version. (There’s a few studio only features, but almost everything is available in the free version of resolve). And a lot of people want to learn resolve anyway for color grading. Why

The new glass look is just so bad. It feels cheap, like a child’s toy. And performance is worse as a result. I’ve turned it off on my phone, via the accessibility settings. But it’s clear Apple doesn’t test the UI layout much with the new g

I also think we have the data in for memory safety in C. Even the best people, with the best processes in the world seem to keep writing memory safety bugs. The “just be more vigilant” plan doesn’t seem to work.

In my experience (several years of writing high performance rust code), there’s only really 2 instances where you need unsafe blocks: - C interop - Low level machine code (eg inline assembly) Most programs don’t need to do either of those t

I love rust, but C does make it a lot easier to make certain kinds of container types. Eg, intrusive lists are trivial in C but very awkward in rust. Even if you use unsafe, rust’s noalias requirement can make a lot of code much harder to i

Many of its biggest benefits of rust come directly from other languages - including Haskell. Like, rust’s Option is identical to Haskell’s Maybe type. Traits are similar to type classes in Haskell, or interfaces in Go. In my mind, the thing

Yep that’s right. I’ve been working on a game with bevy. The Bevy game engine supports being dynamic linked during development in order to keep compile times down. It works great.
733.
by josephg 10mo ago
Well, Rust does support dynamic linking. It just doesn’t (yet) offer a stable ABI. So you need to either use C FFI over the dynamic linking bridge, or make sure all linked libraries are compiled with the same version of the rust compiler.

It’s rarely the thought that counts. It’s the committed effort. Presents aren’t just nice because they needed those socks. More importantly, they’re a signifier that you consider the person to be worth thinking about. You value them enough

Exactly. More expensive than a high end desktop or laptop while having less useful software than an iPad. No thanks. If it were around the $500 point I’d pick one up in a heartbeat. Maybe even $1000. But $3500 is nuts for how little they’re

Ah I see what you're saying. I think the idea is that those asserts should never be hit in the first place, because the code is correct. In reality, its a mistake to add too many asserts to your code. Certainly not so many that perfo

Don't worry, they probably wouldn't want to work with you either. Some programmers think and care a lot about software correctness in a kind of mathematical way. Others just want to ship features and enjoy their lives. Both approa

Yep. I've heard it said that Rust forces you to experience all the pain up front. C will happily compile very broken code. One of my formative memories learning C came after I wrote a function which accidentally returned a pointer to a
