“You can turn it off”, “it’s an optional feature”, they didn’t even last a year! What ever happened to slowly boiling the frog?

I can’t be bothered to build them but looking at the releases on GitHub openssl 3.4.0 is 17.5mb and rustls is 2.6mb. both of these releases are source files not binaries but I don’t see how rustls could possibly be larger than openssl.

Just looked it up, looks like you’re right. The Go GC has to pause when it sweeps and it looks like the JVM has multiple GC implementations but all of them have to pause for sweeps. I don’t really use either language so I didn’t know how the magic worked.

Huh, I knew Go’s GC ran on another thread but not the JVM, cool.

This is because rust doesn’t do proper tree shaking of code and bundles everything into it even if it’s not necessary.

This isn’t true. a simple:fn main() { println!("Hello World!); } compiles into the same size binary as:

fn main() { println!(hello_world()); }

fn hello_world() -> String { String::from("Hello World!") }

fn another_function() -> String { String::from("Completely unused function") }

So why are the complexities of Rust worth it to save like 10ms loading a website? Not that as a language I like php that much due to no typing, but performance for a web app really isn’t that important.

if the amount of rust, c and c++ in web infrastructure doesnt convince you that performance is important then I guess we’ll have to agree to disagree here.

Rust again isn’t that good for embedded either due to the large binary size

I’m not sure about this one, I’ve never worked on embedded but I’m not convinced. There’s an embedded rust book and their target hardware is a device with 256kb of flash memory, and 48kb of RAM.

This can also be solved with a file hash. When you compile the app, ensure the compiled file hash matches the hash of the binary in cargo. So you can get the best of both worlds

This doesn’t address security at all, the only thing a hash does is tell you that the file you download was the file that was uploaded. If I upload malware in my library to cargo, cargo generates a hash for my library, then you download my library. The only thing the hash tells you is that you did indeed download my malware. It’s also harder to audit my library because cargo has a binary blob instead of my code, you have to go to my repo in order to find the malware, and you better hope I haven’t done something clever like add the malware in locally instead of in the repo, so it’s only there when I build to upload to cargo.

Ok, I’m going to just assume this isn’t a troll.

Cargo is doing too many things at once. It’s a build system but also a package manager but also manages dependencies? Idk what to even call it.

I dont even understand your issue? It’s like npm or deno which can run your code, manage your dependencies, etc. How can a JS/TS dev possibly not understand this?

Syntax is very confusing for no reason. You can’t just look at rust code and immediately know what it does. Having to pollute your code &, ? and .clone() everywhere to deal with ownership, using :: to refer to static methods instead of a “static” keyword. Rust syntax is badly designed compared to most other languages I used. In a massive codebase with tons of functions and moving parts this is unreadable.

I dislike ? because I think you should be handling errors as they come instead of sending them up the stack. I also like the explicit .clone() but if you dont want to use it, you can also add Copy to your derive’s and this will make it happen automatically. module::function() generally pollutes code much less then static module.function() or static function() doesn’t it?

Let’s take a look at hashmaps vs json

I hate all of this code, why arent you using struct’s here? In rust its: struct Person {name String, age i32} and in typescript its type Person = {name: string age: number}

Similarly, Async code starts to look really ugly and overengineered in rust.

Sure

Multiple string types like &str, String, str, instead of just one “str” function

I know of &str and String, i’ve never heard of str though so you probably dont need it. &str is a string slice, aka a borrowed String. I generally say you shouldnt be using &str because generally if you get a lifetime error from using it, its because you’re doing it wrong, just use String while you’re learning the only real difference is that String is more verbose then ""

i32 i64 i8 f8 f16 f32 instead of a single unified “number” type like in typescript. Even in C you can just write “int” and be done with it so it’s not really a “low level” issue.

“int” from C is i32, these are int’s and float’s of various bit sizes. i32 = int 32bit, i62 = int 64 bit, f32 = float 32, u32 = unsigned (only positive) int32. but you dont usually need to specify this, rust has type inference. Also speaking of C, what about double, long, short, long long, unsigned long long, unsigned short…

Having to use #[tokio:main] to make the main function async (which should just be inbuilt functionality, btw tokio adds insane bloat to your program) yet you literally can’t write code without it. Also what’s the point of making the main function async other than 3rd party libraries requiring it?

I kind of agree? When async was initially designed it was done as a stackless minimal thing where we could build our own runners (like tokio) but no one really builds their own runners, they just use tokio.

Speaking of bloat, a basic get request in a low level language shouldn’t be 32mb, it’s around 16kb with C and libcurl, despite the C program being more lines of code. Why is it so bloated? This makes using rust for serious embedded systems unfeasible and C a much better option.

I don’t believe you, show me this project. As a personal project I have made a monolithic web server, that handles api calls, webpage calls etc, it uses axum, tokio and serde and when I run cargo build --release it compiles down to a 1.9mb binary. The only way I can see this happening is if you’re not using a release build, which is a concept you should understand as a JS dev.

With cargo you literally have to compile everything instead of them shipping proper binaries. Why??? This is just a way to fry your cpu and makes larger libraries impossible to write. It should be on the part of the maintainer to build the package beforehand and add the binary. Note that i don’t mean dependencies, I mean scripts with cargo install. There is no reason a script shouldn’t be compiled beforehand.

This argument has happened a few times that I know of. This is done for security purposes. If someone ships a binary blob you have to trust it to run, as a community, it was decided that we shouldnt do this.

Another major issue I’ve encountered is libraries in Rust, or lack thereof. Every single library in rust is half-baked.

I kinda also agree with this one, a lot of rust libraries are still in 0.x, I wouldnt call them all “half baked” though. If you search youtube you can find plenty of people using these libraries in prod.

“expect breaking changes” in the readme.

This is not specifically a rust problem this happens with every popular language & framework.

As for “memory safety”, it’s a buzzword. Just use a garbage collector. They’re invulnerable to memory issues unless you write infinite while loop and suitable for 99% of applications.

A garbage collector “freezes” you’re program when it runs usually. There are plenty of cases of people benchmarking rust against go, js, c#, java, etc rust performs vastly better.

Then use C or C++ if you really need performance. Both of them are way better designed than Rust.

Microsoft and Google came out and said that “~70% of their security flaws are a result of memory issues” or something like that. C and C++ are fundamentally flawed, which is why both of those companies have adopted rust.

There are apps with billions of users that run fine on php

True, but the number is going down, which implies a growing number of people choose to stop using PHP, we’re even doing it at work.

Rust is the most overwhelming proof possible to me that programmers are inheritly hobbists who like tinkering rather than actually making real world apps that solve problems

These are fighting words lol. I already mentioned Google and Microsoft have adopted rust for Windows, Chrome and Android. Other companies solving real world problems with rust include, Cloudflare, Dropbox, NPM, Yelp, Discord, Mozilla, Coursera, Figma, Facebook/Meta and Amazon.

Typescript is easy, rust is not. Typescript is therefore better at making things quick, the resourse usage doesn’t matter to 99% of people and the apps look good and function good.

What are you building where the end user doesn’t care if the app performs well? Not caring about resource usage results in poor performance which results in dissatisfied users/customers which stop doing business with you. Have you heard about the unending war in JS land against bundle size?

So at this point I’m seeing very little reason to continue. I shouldn’t have to fight a programming language

No one is required to like every programming language, If you don’t like rust, stop using it.

IMO the best way to start in a new language is to rewrite some of your previous projects in that language.

I generally start out by rewriting a couple simple 1-3 function console apps, basic leet code stuff like; palindrome, fizzbuzz, reverse an array in place, etc, and some simple unit tests for them. Then I go ahead and rewrite some of my previous projects or uni assignments in that language.

At that point I generally have a good understanding of basics and have an idea of how to approach a new project. When I got to this point in rust I then started on threading, async, why it’s easy to return a String and an ordeal to return &str, etc.

Something I’ve always found funny about the “AI will replace programmers soon” is that this means AI’s can create AI’s and isn’t this basically the end of the economy?

Every office worker is out of a job just like that and labourers only have as long as it takes to sort out the robot bodies then everyone is out of a job.

You thought the great recession was bad? You ain’t seen nothing!

In the case of docker I’m already at the point where I no longer think it’s necessary. At my current job our stack is JS, PHP and Python. 3 interpreted languages, we then build on Ubuntu and deploy on Ubuntu. I don’t think our project really needs docker, even though it does use it. We also have wasm/wasi prepping to eat Docker’s lunch.

I’m not against immutable distro’s on principle. I imagine they still have some kinks to iron out, but I haven’t looked in on them for a while.

My opinion on these things is; if it’s a superior system, then it’ll become the new standard, that’s always what happens, and the naysayers are largely irrelevant. Just like computers, smart phones, the internet, etc.

I started learning Lua for a WoW add-on. Not even making my own add-on, just tweaking someone else’s.

Maybe this is a case of hindsight being 20/20 but wouldn’t they have caught this if they tried pushing the file to a test machine first?

If you look at projects in more popular languages like JS, Rust, Python. There is plenty of new blood in the contributors list. I won’t speculate as to why, but it looks like the new generation doesn’t like c and c++.

I think this is also backed up by the Linux kernel and thunderbird projects. Both are old c/c++ codebases and both have stated they are adopting rust in hopes of drawing interest (and contributors) from the rust community.

IMO, I’d say Dioxus is more of a portable front end framework. If you’re looking for an electron alternative i.e, something to run web applications like they are native apps, I’d recommend Tauri.

Also, this might be a bit out of date, but I believe Dioxus is using Tauri’s stuff under the hood. Although I heard this before the dev went full time on Dioxus, it could’ve changed, I know they have done a lot of work on it.

To do quick and simple explanations:

var test int = 0

assign an int, var = let in rust land

:= 

This is basically an inferred assignment e.g.

a := "hello world"

The compiler will know this is a string without me explicitly saying

func (u User) hi() {}

To return to rust land this is a function that implements User. In OOP land we would say that this function belongs to the user class. In Go, just like in rust we don’t say if a function returns void so this function is for User objects and doesn’t return anything:

func (u User) hi(s string) string {}

If it took in a string and returned a string it would look like this.

map[string] int {}

I will give you that this syntax is a bit odd but this is just a hashmap/dictionary where the key is a string and the value is an int

Bruh, I do this all the time! Can’t solve a problem? Get up and walk around the house while I explain the issue to imaginary people!

I feel like helium works as well as helix. When I search Helix I don’t get the editor but if I search Helix Editor I will get what I’m looking for.

When I search Helium editor I don’t get any exact matches, but of course SEO is a dark and mystical art so your mileage may vary.

I like how at the start of the line it explicitly says “out of memory” but we’re just pretending this is some satanic bullshit.

She obviously read the error to find “kill process” and “sacrifice child” but still ignored the memory error

Add Exporters MVP

At work we have a lot of old monolithic OOP PHP code. Dependency injection has been the new way to do things since before I started and it’s basically never used anywhere.

I assume most people just find it easier to create a new class instance where it’s needed.

I’ve never really seen a case where I think, “dependency injection would be amazing here” I assume there is a case otherwise it wouldn’t exist.
