Using smart pointers doesn’t eliminate the memory safety issue, it merely addresses one aspect of it. Even with smart pointers, nothing is preventing you from passing references and using them after they’re freed.

Would you have a link to that? I know there are many third-party garbage collectors for Rust, but if there’s something semi-official being proposed or prototyped I’d be most curious :)

Cool, that was an informative read!

If we were willing to leak memory, then we could write […] Box::leak(Box::new(0))

In this example, you could have just made a constant with value 0 and returned a reference to that. It would also have a 'static lifetime and there would be no leaking.

Why does nobody seem to be talking about this?

My guess is that the overlap in use cases between Rust and C# isn’t very large. Many places where Rust is making inroads (kernel and low-level libraries) are places where C# would be automatically disqualified because of the requirements for a runtime and garbage collection.

I think that’s very team/project dependent. I’ve seen it done before indeed, but I’ve never been on a team where it was considered idiomatic.

I don’t know about your workplace, but if at all possible I would try to find time between tasks to spend on learning. If your company doesn’t have a policy where it is clear that employees have the freedom to learn during company time, try to underestimate your own velocity even more and use the time it leaves for learning.

About 10 years ago I worked for a company where I was performing quite well. Since that meant I finished my tasks early, I could have taken on even more tasks. But I didn’t really tell our scrum master when I finished early. Instead I spent the time learning, and also refactoring code to help me become more productive. This added up, and my efficiency only increased more, until at some point I only needed one or two days to complete a week’s sprint. I didn’t waste my time, but I used it to pick up more architectural stuff on the side, while always learning on the job.

I’ll admit that when I started this route, I already had a bunch of experience under my belt, and this may not be feasible if you have managers breathing down your neck all the time. But the point is, if you play it smart you can use company time to improve yourself and they may even appreciate you for it.

If we’re looking at it from a Rust angle anyway, I think there’s a second reason that OOP often becomes messy, but less so in Rust: Unlimited interior mutability. Rust’s borrow checker may be annoying at times, but it forces you to think about ownership and prevents you from stuffing statefulness where it shouldn’t be.

You can use the regular data structures in java and run into issues with concurrency but you can also use unsafe in rust so it’s a bit of a moot point.

In Java it isn’t always clear when something crosses a thread boundary and when it doesn’t. In Rust, it is very explicit when you’re opting into using unsafe, so I think that’s a very clear distinction.

Java provides classes for thread safe programming, but the language isn’t thread safe. Just like C++ provides containers for improved memory safety, and yet the language isn’t memory safe.

The distinction lies between what’s available in the standard library, and what the language enforces.

Modern C++ does use references, which can also reference memory that is no longer available. Avoiding raw pointers isn’t enough to be memory safe.

While I can get behind most of the advice here, I don’t actually like the conditions array. The reason being that each condition function now needs additional conditions to make sure it doesn’t overlap with the other condition functions. This was much more elegantly handled by the else clauses, since adding another condition to the array has now become a puzzle to verify the conditions remain non-overlapping.

I find Linear to be reasonably pleasant.

Issue resolved

Finding a Webpack replacement that doesn’t use NPM at all is going to be hard, but there are certainly alternatives that don’t require the 1000+ NPM dependencies required to use Webpack.

Some alternatives you can consider are Rsbuild and Farm. Part of the reason they use so much fewer NPM dependencies is because they’re written in Rust, so they’ll have Cargo dependencies instead, but you shouldn’t notice anything of that. Of course if you want to audit everything it’s not that much easier, but at least the Cargo ecosystem seems to have avoided quite some of the mistakes that NPM made. But yes, in the end it still comes down to the extent that you trust your dependencies.

Yeah, I mix them too, although I apply quite a bit of functional techniques especially at the architectural level as well. OO I use mostly for dealing with I/O and other areas where statefulness cannot be avoided.

If you’re interested, I also wrote an in-depth blog where I touch on these topics: https://arendjr.nl/blog/2024/07/post-architecture-premature-abstraction-is-the-root-of-all-evil/

Just keep in mind that inheritance is nowadays a very contested feature. Even most people still invested in object oriented programming recognise that in hindsight inheritance was mostly a mistake. The industry as a whole is also making a shift to move more towards functional programming, in which object orientation as a whole is taking more of a backseat and inheritance specifically is not even supported anymore. So yeah, take the chance to learn, but be cautious before going into any one direction too deeply.

and that burden is as far as I’ve seen being forced on those long term contributors.

This is not what is happening. The current long term contributors were asked to clarify semantics about C APIs, so the Rust maintainers could take it from there. At no point were the C maintainers asked to help maintain the Rust bindings.

I think I would put the emphasis slightly differently: I don’t feel the confusion is around the word “spawn”, but it spawns futures rather than tasks. For tasks you might indeed expect them to be picked up in the background (which is what work-stealing does), but futures only execute when polled.

I was aware that indeed the trait and lifetime bounds were an artifact of the Tokio work-stealing behavior, but Evan makes a very well-explained case for why we might want to consider stepping away from such behavior as a default in Rust. If anything, it makes me thankful the Rust team is taking a slow-and-steady approach to the whole async thing instead of just making Tokio part of the standard library as some have wished for. Hopefully this gets the consideration it deserves and we all end up with a more ergonomic solution in the end.

0° being “very cold” and 100° being “very hot” is intuitive.

As someone who’s not used to Fahrenheit I can tell you there’s nothing intuitive about it. How cold is “very cold” exactly? How hot is “very hot” exactly? Without clear references all the numbers in between are meaningless, which is exactly how I perceive any number in Fahrenfeit. Intuitive means that without knowing I should have an intuitive perception, but really there’s nothing to go on. I guess from your description 50°F should mean it’s comfortable? Does that mean I can go out in shorts and a t-shirt? It all seems guesswork.

As a junior with no clue how to write production code, is Clean Code going to provide with a decent framework I can quickly learn to start learning my craft, should I throw it out completely because parts are bad, or should I read both Clean Code and all its criticism before I write a single line?

I see what you’re getting at it, and I agree we shouldn’t increase the load for juniors upfront. But I think the point is mainly there are better resources for juniors to start with than Clean Code. So yeah, the best option is to throw it out completely and let juniors start elsewhere instead, otherwise they are starting with many bad parts they don’t yet realize are bad. That too would increase cognitive load because they would need to unlearn those lessons again.

I thought we were talking about gamers and Linux users? :p
