Yeah, Lemmy is actually a decent software for this use-case…

Not if you never get your application into production…

I wish this was as much of a joke as I’m pretending. It’s so common for software projects to get cancelled that lots of tooling differences are just in terms of how long they let you not deal with long-term problems and how violently they do then explode into your face.

For most of the development lifecycle of a GCed project, you’re gonna ignore memory usage. And if you’re lucky, it can be ‘solved’ by just plonking down a thiccer piece of hardware…

I mean, he did fuck up a good chunk of everything…

Ah, interesting. I went from garbage-collected languages where thinking about ownership might be useful for keeping complexity low and occasionally comes up when you manage lists of objects, but ultimately isn’t needed, to Rust where well-defined ownership is enforced by the language.

So, I wasn’t aware that ownership is even as concrete of a thing in other languages…

A local shop here only has shopping carts, no baskets. You can get smaller shopping carts, and in fact even shopping carts for toddlers to push around, but you still need a coin for those.

And yep, I’ve genuinely been stood in front of that shop and went back home, because I didn’t have an appropriate coin. I think, even twice already.
I could have bought a small item to have them hand me out coins and then done another loop with the shopping cart, but yeah, there was just no way, I’d waste that much time.

Interesting. Presumably, enough of their customers now show up without the appropriate coins, due to electronic payment methods being available otherwise, that they decided to not require coins.

Here in Germany, where we hold onto cash a bit more dearly due to our Stasi-past, I don’t know any shop where I can take a shopping cart without sticking a coin in…

Yeah, this is a rather US-specific meme…

Yeah, so much of it is a mediocre/old joke overlayed on a generated image.

I’m guessing, there’s people out there, who genuinely just flood social media with these mediocre posts to try to grow accounts or similar…

Hmm, not sure, if I’ve heard of it. I’m guessing, we’re not talking about simply drawing a UML class diagram…? Is it for figuring out which object will have to clean up which other objects, in non-GCed languages?

As far as I’m aware, the microfiber cloths specifically made for dusting have a structure like this:

So, it isn’t (intentionally) rough either. You wouldn’t really scrub with these. But yeah, certainly not ever going to be silky smooth either…

To me, it feels almost like I’m touching very fine-grained sandpaper…

Is that usable for dusting then, or is that for something else? I feel like for dusting, you want a somewhat rougher structure, so it can hold the dust better…

Dry skin is mostly caused by not enough oils being on your skin, which normally prevent the water from escaping. You’ll have a hard time hydrating so much that that’s no problem at all.

But at the same time, the cheapest lotion will do the trick. In principle, you can even use sunflower oil or similar. The water isn’t picky from what oil it gets blocked…

Yeah, these become a lot less relevant with routine.

• Avoiding the main-thread panicking is mostly just a matter of not using .unwrap() and .expect().

• String vs. &str can mostly be solved by generally using owned datatypes (String) for storing in structs and using references (&str) for passing into function parameters. It does still happen that you forget the & at times, but that’s then trivial to solve (by just adding the &).

• “temporary value dropped while borrowed” can generally be avoided by not passing references outside of your scope/function. You want to pass the owned value outside. Clone, if you have to.

• “missing lifetime specifier” is also largely solved by not storing references in structs.

The thing with OOP, particularly how it’s used in GCed languages, is that it’s all about handing references out to wherever and then dealing with the complexity of not knowing who has access to your fields via getters & setters, or by cloning memory whenever it’s modified in asynchronous code.

Rust has quite the opposite mindset. It’s all about tracking where references go. It pushes your code to be very tree-shaped, i.e. references typically¹ only exist between a function and the functions it calls underneath. This is what allows asynchronous code to be safe in Rust, and I would also argue that the tree shape makes code easier to understand, too.

But yeah, some of the patterns you might know from OOP will not work in Rust for that reason. You will likely need to get into a different mindset over time.

Also just in case: We are talking OOP in the sense of the paradigm, i.e. object-oriented.
Just using objects, i.e. data with associated functions/methods, that works completely normal in Rust.

¹) If you genuinely need references that reach outside the tree shape, which is mostly going to be the case, if you work with multiple threads, then you can do so by wrapping your data structures in Arc<Mutex<_>> or similar. But yeah, when learning, you should try to solve your problems without these. Most programs don’t need them.

Yeah, we onboarded some folks into a Rust project last year and a few months in, they were genuinely surprised when I told them that unwrapping is pretty bad. Granted, they probably did read about it at some point and just forgot, but that isn’t helped by lots of code using .unwrap() either.

Can still use .is_positive(), though…

I was also surprised how well it works, but you genuinely just sploosh water with a mild bit of pressure at it and it comes off.

I’ve been using a hand-operated travel bidet, which is basically just a squeeze bottle with a nozzle, and that still gets me perfectly clean. Definitely much cleaner than with toilet paper.

Does cow milk bubble in some special way? Like, you can make bubbles rise even in water, but I’m guessing, that’s not what we’re talking about…

The thing is that many people who “like milk” don’t think of the taste of freshly milked dairy milk. I grew up with skimmed milk that got treated with ultra-high-temperature processing. The cow taste was hardly there and it wasn’t why I liked milk.

I liked milk, because it made cereal edible and because I could put chocolate powder into it. The cow taste rather even felt out of place.
