  • performance

    Like raw runtime performance, if I write the code in python, it’s ~ 100x slower than in Rust. You often get away with dumber stuff in Rust as the compiler is able to optimize it well. With python you would have to write your native bindings either in Rust/C or C++. So why not straight use Rust (as the other choices aren’t sa(f/n)e at this point anymore).

    Afaik you can just go to definition in literally any language, typing or no.

    No you can’t, at least not in the same way that a static type-system allows. As dynamically-typed programs are evaluated on runtime, so you often don’t know at the time while coding what is run. In untyped/dynamically typed languages you often use heuristics to jump into stuff, which is just less precise.

    There’s more to this, but I think you get what I mean, when you programmed more intensively with static generics in Rust (compared to something similar in say javascript or python without types), IDE experience is just more precise and correct (and more fun).





  • Nah it’s also a language matter. People complain about Rusts complexity, meanwhile I complain about everything else in other languages, and am faster than in any other language, not necessarily because writing code is faster, but because I am able to just focus on writing code. I cannot tell that about other languages, because e.g. the packaging system is bad, or configuring an environment, or debugging stuff which a strong type-system would have caught already. Also IDE experience I think is the one thing that keeps me away from dynamic languages. Rust analyzer is so much better than anything else I’ve tried, and it keeps getting better (e.g. recently it was added to show whether a trait is object safe or not, and why it is not).

    Another thing that is often missed when comparing static with dynamic languages is just performance, python heavily relies on stuff written in a system language, as soon as a hot-loop is written in python, things get bad


  • I haven’t, but everytime I try python I want to quit it so quickly because of the messed up packaging system and more importantly IDE experience (and I don’t think unless you are extremely disciplined with type annotations, that you’re getting even close to rust-analyzers performance). I enjoy just exploring dependencies with go to definition, and the trust I can have in the type system.

    I’m swearing everyday in my job about typescript, which is just javascript with leaky and unnecessary complex type annotations. So yeah I even consider typescript bad (and I doubt that python is better with type-checking).
