Being able to tell the definition of a monad is quite different than really understand what is a category, what's an endofunctor and, finally, what's a monoid. All of those concepts are taught in an Algebra 1/2 class. That being said, I really advise against giving the said definition when explaining what's a monad in a programming language, what does it do and why it exist.

Being ancient (73) I am enjoying Rust. This is because I started with assmbler and C when hitting the hardware, and having learnt about foot damage I understand the ideas that Rust brings. Perhaps the way to learn the benefits of Rust is to try the job in C, fall down the hole, and then harness Rust. (Although I am fond of C, and modern compute machines can do all the splendid compilation and build checks that a PDP-11 would take a week)

I am so glad you mentioned cloning over and over because I preach it to others haha. The single most helpful thing I did for learning rust is NOT to borrow. Lots of cloning, returning objects over and over. It got me used to data lifetimes and moves. By making it redundant I understood it. Then borrows felt like a natural optimization. It created a gentle learning curve. I mentor a lot of junior devs and the dopamine hit of getting something that works is ESSENTIAL for motivating newbies hahah.

@NoBoilerplate Год назад

I'm delighted to have your account, thank you!

@TehKarmalizer Год назад

As someone who knows that copying and cloning is “slower”, I didn’t take that approach. But I can honestly say cloning and copying everywhere is a much less painful way to learn.

@illegalsmirf Год назад

It's far more important to discourage newbies by constantly reminding them that there are better ways of doing it, endless frameworks, approaches and new programming languages to learn. Then they will realize how futile it all is and the desperate need for widespread automation.

@CottidaeSEA Год назад

That's the way I make just about anything in Rust. Unless I know immediately that "this function will always only have a reference" I will simply resort to cloning. Prototyiping becomes at least twice as fast, and when everything seems good enough I can just start replacing parts of the code to avoid cloning everywhere. The performance is more stable than a GC language even when ruining it with cloning regardless though. To clarify the last part, it's not necessarily much faster if done "incorrectly", but you avoid GC spikes.

@theroboman727 Год назад

@@NoBoilerplate That won't really happen, for the same reason that you cant omit types from function signatures, it simplifies type inference a lot for the compiler and for humans as well. Rust really looks at only one function at a time. It only sees the current function body and signatures of called functions, so you need to inform it about the lifetime relationships between values. This too is also a readability advantage for humans. I think the error messages will get better if anything changes with them.

How to learn the benefits of Rust: First attain 15 years of working experience in C, C++, asm, JS and Python. Do all sorts of projects in them, across all sorts of scales. See what sorts of problems plague each of them. And then go to Rust. You'll now have motivation to breeze through the initial vertical climb, to the lands of joy beyond.

@@ashen_dawn I'm not totally against that idea, but I'd suggest that if a new coder is excited by what they hear about rust, let them code it - all languages are pretty much the same - we're only talking about 1-2% difference in day-to-day life (though I obviously REALLY LOVE that 1-2% difference!)

9:17 A little extension to this part: Use references in function parameters. There are other places where using references can mess you up, but in function parameters that can't really happen. You don't need to reference number types though, passing a reference is just as or more expensive than passing the thing itself.

@NoBoilerplate Год назад

Yeah, totally agreed, this sort of nuance you pick up in intermediate Rust.

@carlosmspk Год назад

I think this isn't 100% true. I think that, for beginners, mainly people coming from GC languages, it's important to get used to how data flows, and drop the reference usage when unnecessary (given that pretty much any GC language just uses references everywhere). It forces you to think a bit more functionally, which Rust incentivizes, and as bonus, code is easier to read. It's a purely "psychological" difference, but I think it matters

@tordjarv3802 Год назад

There is a slight misunderstanding in this comment. In rust you don't think in terms of pass by value vs pass by reference, you think in terms of borrowing a value vs taking ownership of a value. It is up to the compiler to determine if values should be copied or passed by reference, in fact only types that implement the copy trait can be thought of in pass by value vs pass by reference terms, but it is better to always think in terms of borrowing and taking ownership otherwise you might end up in strange situations. Also a type should only implement the copy trait if it makes sense that a value should be copied bit wise (because that is what the Copy trait is for) otherwise you should use the clone trait instead.

I find the difficulty of lifetimes to be analogous to the difficulty of Rust as a whole: it forces you to think about things up front that you can, in other languages, either ignore entirely (Python, JavaScript, and sometimes only up to a point), or spend endless painful hours debugging under higher technical debt pressure later on (C, C++).

@NoBoilerplate Год назад

That's a great way of looking at it

@dragon_pi Год назад

this is a pretty good way of learning it! i especially like the re-taking test comparison: when i learned rust, i look up the very basic syntax, then i tried (and obviously failed, as expected) to write a medium sized project. In that way i also learned what to do better next time. when I *really* learned afterwards (aka reading the rust book, as one does) and made stuff that actually worked, the realization "ahh, thats how you do it, now i know what i did wrong" was amazing! this early designed-to-fail project helped me get a feeling for what i needed to learn

Coming from Haskell to Rust i appreciate how nice the ergonomics of tooling and how large the ecosystem already is. Every important library is sufficiently documented, the compiler is so quick and helpful, for every problem there seems to exist a library you can build upon, and you can prototype quickly with lots of copy and clone but the code is still frickin fast.

@NoBoilerplate Год назад

@miguelguthridge Год назад

One thing that I think is especially difficult to learn is working around the borrow checker, but even more importantly, knowing when you shouldn't work around the borrow checker. When I just started learning Rust, I had worked on a project where my design didn't really work well with the borrow checker at all. No matter what I tried, it wouldn't compile. At the time I remember being extremely frustrated with Rust, however in hindsight I now see that the reason the borrow checker didn't like my code is because it wasn't well-designed. I would have saved so much time if I had just planned ahead and come up with a design that didn't have circular dependencies. Even in languages without a borrow checker, designs like that will eventually be your downfall - I've had many projects devolve into an unmaintainable mess due to poor planning. Basically, while I didn't realise or appreciate it at the time, Rust's design was pushing me towards better software design from the get-go.

@NoBoilerplate Год назад

That's a really great take and one I was helping a patron I'm mentoring out with. Tree structures are REALLY easy to reason about so long as they don't have cycles! Nice!

@TehKarmalizer Год назад

That kind of inversion can be really useful, though, like when parents know about their children, but children also know about their parents. It can be done in roundabout ways, but they may be more prone to other kinds of programmer errors than simply allowing that kind of relationship.

In a critical undergrad course (Organic Chemistry), the professor would hand out a pre-test. Most students ignored it for the first couple of tests, but having done the pre-test, I noticed a pattern. Most all Organic Chemistry reactions are totally reversible, It is often the conditions of the reaction that push it one way or another. What the prof had done was have us do the steps of the reaction in one direction, doing “electron tracing” in each step. On the TEST, he had questions on the reverse reaction. Bingo!!!! I picked up on this and scored a 100% on all my exams. I tried to get other students to study with me. The few that did wound up making A’s in the class. It is a perfect example of “Test to Learn” and seeing patterns.

Done many languages for backend high-performance systems for more than 20 years(C++ / C#), and rust fits in my head for more reasons. The only thing, I hope that there will be better IDE's (with better refactor tooling) and that there are more packages/crates that are stable and at least version 1.0. This is the jobs for us as a community. Thanks for the info and tips!

@NoBoilerplate Год назад

Two thoughts come to mind about that: 1. VSCode with rust_analyzer is really very good. Refactoring, following code definitions etc, there's a LOT there, just right click! (map it to a hotkey once you use it a lot) 2. Rust crates don't get abandoned before 1.0, they just are finished. The language is so good at up-fronting all cases, that I trust a 0.2 rust crate significantly more than a 1.0 python package!

The problem with cloning is that you will lie awake at night thinking about how your could remove it. Even if it barely affects the performance of your code. I have one problem I've been stuck on for 3 years where I wanted my function to take in an iterator and return an iterator, rather than having to collect() it into a vector. Problem is along the way a new struct gets created that the resulting iterator must hold as a reference. Tearing my hair out about how to make that struct live long enough.

@sebastiangudino9377 Год назад

I fully agree with the "No references only copying" tip. They way rust handles solves the memory management problem is by a logical enforcement and tracking of move semantics (By using the abstraction of 'Borrowing'). If you are a C++ developer. Move semantics are one of the most complex advanced topics that you will have to deal with. Having rust developers have to worry about that from the start is madness. Specially when they come from high level languages and they don't even know about pointer or "The heap"

Great video as always. I'm always talking about Rust to developers. The learning curve is always a turnoff, but I often explain (as you do) that it's steep, but flattens of rather quickly. The other worry is having to worry about things they didn't used to, so I also suggest they can go really deep with memory concerns, or just ignore that, clone everything, and worry about performance later. Inevitably, they're already picking up using references before it ever gets to a performance issue simply because they're modeling their problem more correctly now. So this video is rather validating for me.

Here is my dilemma: Yes rust is cool, and it can be fast, and it can be elegant etc. But in the real world, the C# JIT is so good that often the c# version of my app is faster than the rust version. Because all this added complexity nukes my ability to build the abstract ideas in my head first and just type them out. Now all of a sudden I have to have this hierarchy of ownership that locks down my architecture. If I discover a problem and need to redesign, it often breaks the entire ownership chain and requires me to basically start again. In C# I just change it, and the JIT does all that work for me

though you cant deal with unpredictability of jit, after you refactor some things in c# you never know how fast it will be, and with rust you almost certainly know it would be al least as fast (with some exceptions ofc)

The thing I find most awesome about Rust is that if it compiles, the program works flawlessly almost EVERY SINGLE TIME. As a game programming hobbyist, I can honestly say I made more progress in a mere 3 months with Rust (while learning it on the fly, no less), than I had in the previous 3 years using C.

9:55 When I was new to Rust, I didn't fear using references, even if they had lifetime annotations. Now, years later, I try to avoid explicit lifetimes alltogether and only use them if there is no chance to avoid them. But there are a few cases where I really want lifetime annotations, especially in structs. Normally when I want some kind of accessor to some data, which should not be modified or go out of scope as long as the accessor exists. For example I used this to call some function safely. Calling the function is only safe if I specify a valid parameter. So instead of calling the function directly, I created a struct, which lists all valid parameters, and in order to call it, I only specify the index of the parameter I want to call. But iterators are also a good example for this.

4:30 What you talk about here is a concept I discovered while learning to do various creative things digitally. Knowing what is possible first is a major key to learn MUCH faster. I had watched photoshop videos for years up until I finally pirated it in 9th grade. Took me little to no time to learn the tools 1 by 1, and pretty soon I was making decent edits. And now, about 2 weeks ago I took a photo of myself for my LinkedIn, and noticed some tape on the wall behind me. Because I took the picture in my room and I have sheets of paper with plans and stuff hung up to keep me in the right headspace. In like 5 minutes I had a perfect wall behind me with 0 blemishes of any kind, my hair was not messy at all and my suit jacket had no lint on it.

great video as usual! did not expect to see a reference to haskell in a video about learning rust! that was a surprise! but a very good proposition. i'm in the process of learning rust after many years of being a professional js developer, while i'm still far away from being able to do any significant functionality in rust, i'm starting to really understand and appreciate its syntax and the benefits that come along with it. funnily enough, the concept of borrowing and ownership was probably the least complicated thing for me to understand, it was a lot more about traits and enums and all those things since i never really had much experience with typed languages. Looking forward to a future filled with many rust jobs and no more javascript pain.

I started my programming journey with Python, and I still love the language for its simplicity and its ability to set things up and going. Then I heard about Rust, about how memory safe it is. It is a big step up, code seems harder to read at first. But the more I read, break down the syntax to understand what it does, I found clarity in Rust, it's predictable, it does what you tell it to and just you, or it can refuse to compile straight up, it wants you to be precise, and that has been the thing driving me to keep learning it.

Great guide, I followed it by reading ultralearning, the rust book and now I'm working through the exercises. Really great method for being able to recall "oh I remember something about blank, I know how to solve this or look for more info". (Context I have been a C#/js developer for a while so programming isn't new) Some examples: - rust needed linker.exe to compile properly, I remembered from the book that this is a tool that C++ uses to make exe files, I added C++ development with VS build tools and it works. - cargo install isn't working, oh yeah this is the rust package manager, ok cert issue is probably due to some firewall/config issue - this exercise can be solved by adding a return statement OR if I remove the semi-colon, rust knows that the value is being returned - oh yeah you can redefine variables in a scope and it doesn't change the outer one - variables are immutable by default, that's right I can use the mut keyword!

The deeper I got into JS, there more janky it felt. Watch any JS tutorial and they will undoubtedly start with bringing in a half dozen libraries. And that's just to get started.

@jesuszorrilla7941 Год назад

Most of those are not necessary. You can build fast JavaScript UI by abstracting de default document createElement method the way you want, so no libraries, no installs, no nothing. Also jsDoc works really well, so no compilation needed (you can also get typescript types intellisense without adding a compiler using it) Node has an http server library by default, and while routing is not so polished as when using express, you dont need to care about libraries at this point. There are only so many things you'll need: 1. A server.js with default http module to serve your file 2. An html file to load your script 3. An script calling/importing/loading everything the vanilla way So no need for any fancy framework or library if you are starting... Note: you can bypass bundles by creating an async function that adds an script tab to load files and cache it on a global object, next you'll need to just await myrequirefunction(src)

By default js can handle webgl, image processing, audio, video, ui, http requests, web sockets and even databases without loading any library (it depends if you are on browser or a server)... Most of those things will need a library in rust, that may make the final product into the MBs realm really fast, while a js project is still in the manageable realm. So, its not fair to say you need many libs in js and not in rust
