  • I haven’t used npm. But pip is horrible. Some times I’ve used a well-known library that only works on linux, but there is no mention of it whatsoever, and it installs without problem. The error only happens at run-time (not even when importing!) and says nothing about platform-dependency. I only learned that it was a linux-only library because I happened to try running it on a Linux machine to see if it worked.

    Many times you have to set up your environment a specific way (environment variables, PATH, install dependencies outside of pip) for it to work, and there’s no mention of it anywhere. Sometimes you install the library with pip, sometimes with apt, and there is no way to know which one. And sometimes the library is both in apt and pip, but the pip one does nothing.

    Furthermore, good luck importing a library. You might have installed it with “pip install my-library” but to import it you have to do “import MyAwesomeLibrary3”. And pip won’t tell you about that.








  • To be fair, mechanic items, and especially electronic ones were far more repairable back then.

    You could see, desolder and solder components without issue. Nowadays most of the electronics are inside chips, and only the components that need to be physically big (like those responsible for the power supply) are human sized. Sure, there are some small SMD that can be manually diagnosed and replaced, but even then you often need a lot of skill and equipment.



  • The good thing about Box::leak() is that it returns a raw *mut pointer. So you need unsafe{} to dereference it. Might as well: let my_ref = &mut unsafe{*ptr}; while you are at it, so you have a perfectly normal rust reference, so the function signatures don’t need any change.

    The problem with Rc is that it would also require a RefCell most of the time. So the whole thing would be filled with Rc<RefCell<T>>. With the required .borrow_mut(). It would both do a pain to do and undo.

    And of course I want to undo it, because RC is a shitty GC.






  • Using “clever” ways to disable the borrow checker is one of the few things I don’t like about rust. I much rather it having a “borrow checker version” and a “garbage collector version”. That way we could rapidly iterate through design choices with the GC, and once the design has proven good, apply lifetimes and such to use with the borrow checker. The only downside to this I can think of is that most would just leave it in the GC version and not bother to move to borrow checker. But that’s fine by me, rust has many other features to take advantage of. As long as no GC libraries are allowed in crates.io, it should be fine.
