For sharing awful code theres also Programming Horror.
"Rust's compiler prevents common bugs" So does skill. No offense to you, but, this trope is getting so tiresome. If you like the language then go ahead and use it. What is it with the rust crowd that they have to come acrosslike people trying to convert your religion at your front door?
I can sympathize with some people getting tired of "rewrite it in Rust", especially when it's suggested inappropriately. (Worst I saw was an issue opened on something, maybe a database, I don't remember. Someone said they were a new programmer and wanted to help and only knew a little Rust and that if the project was rewritten in Rust they could help.) But... Rust's compiler being able to do those things is actually super useful and amazing. This is like someone saying they don't need static types because they know the language good enough to not misuse the dynamic types. This is like someone saying they don't need C because they're good at assembly.
While it isn't something as simple as Rust being strictly better than C/C++, it's really silly to say that you being a good developer means you don't need guardrails. Everybody makes mistakes all the time. You're not perfect.
At my last job I worked in a code base written in C and it needed to be certified to MISRA level A, and even in a language with as many foot guns as C, it's possible to write safe code. You just need to know what you're doing. I know there are tons of Rust zealots out there claiming it'll solve every last problem, but it turns out you just need to be careful.
it turns out you just need to be careful
Famous last words
In summary: use rust.
it always astounds me how utterly arrogant people are about their own abilities. (myself included) but seriously who the fuck doesnt like having something that just prevents you from doing things that are obviously broken and not going to work?
It’s like going to city hall and complaining your tax dollars are being spent on guardrails along the road that you haven’t personally ever driven into.
I don't agree with /u/red-crayon-scribbles ' approach to memory safety, but what you're saying isn't entirely true either.
It is possible to manipulate memory in ways that do not conform to Rust's lifecycle/ownership model. In theory, this can even be done correctly.
The problem is that in practice, this leads to the following, many of which were committed by some of the most highly skilled C developers alive, including major kernel contributors:
...echoing statements expressed by hundreds of thousands of programmers who use the only language where 90% of the world's memory safety vulnerabilities have occurred in the last 50 years, and whose projects are 20 times more likely to have security vulnerabilities.
ooof.
Your first point is not true. There are valid uses of memory sharing that rust will reject.
At this point, I've seen far more people being almost violently anti-rust than I've seen people being weirdly enthusiastic about rust. If Rust people are Jehovah's Witnesses, then a lot of the anti-Rust people are ISIS.
i think one factor (though definitely not all) of the dislike is the politics of the project, which are fairly inclusive and kind. some people can't stomach that. another factor might be that the mere existence of rust implies that a lot of people are not the 100x rockstar developer they might aspire to be. maybe it's also just a simple change = bad. though i have seen people who dislike rust also gravitate towards zig, and that also has some big differences. maybe it's a hate towards mozilla? when i talk to people who hate rust they don't articulate themselves well, so i have to speculate and i get nowhere. one thing i do hear about rust a lot is that it's ugly, but I don't really get that. i can't personally fathom disdaining to use a tool simply because of looks, and i also don't personally think rust is ugly.
The human mind has limited capacity for things to pay attention to. If your attention is occupied with tiptoeing around the loaded guns scattered all over the floor, sooner or later you’ll slip and trip over one.
Of course, you’re a virtuoso programmer, so you can pirouette balletically around the floorguns as you deliver brilliantly efficient code. Which is great, until you have an off day, or you get bored of coding, run off to join the circus as a professional knife-juggler and your codebase is inherited by someone of more conventional aptitude.
Programming languages offering to keep track of some of the things programmers need to be aware of has been a boon for maintainability of code and, yes, security. Like type systems: there’s a reason we no longer write assembly language, squeezing multiple things into the bits of a register, unless we’re doing party tricks like demo coding or trying to push very limited systems to their limits.

Sometimes you even have to deal with having mere mortals on your team!
“Should I use rust or c++” is the wrong question IMO. The right question is “do I want the code I run, written by thousands or millions of randos, to be written in rust or c++”.
Unlike you babies I have Personal Responsibility and I write all of my code directly in assembly the way reagan intended. I don't need guard rails and I've never had any issues with it because my Personal Responsibility keeps me safe
Magnetised needle and a steady hand or gtfo
Skill issue takes are dumb as fuck. It's just republican personal responsibility takes using different language.
Intelligent people focus on producing systemically better outcomes.
The problem with these followers of rust is that they're heathens, disbelievers and worshippers of the devil. Just like all of you heretics. There is just one programming language for the true believer and it is FORTRAN. The pure and true FORTRAN, that is, which is punched into cards of virgin paper, not the heresy created by the blasphemy of 99.
C's compiler prevents common type bugs and handles things like register allocation for you? So does skill.
I love this argument because it means this dude is the only skilled C developer on the planet. Chromium devs are just chumps that should be replaced by this uncommon God.
While I do totally see the advantages of rust and agree skill is not a solution given people make mistakes...I do agree a lot of the very vocal rust advocates do act almost religious and it is an annoying turn off.
I'd guess it's Rust fan's genuine belief that they have something revolutionary.

If you're that much of a galaxybrain, you should be writing everything directly in opcodes. In reality, nobody is, and we invented languages to help us perform an activity the human brain is very poorly suited to.
This attitude also means that OP stares at their own obvious bugs on a screen all day and then decides they're great, which is level of detachment from reality frightening to me.
Sadly, it is a detachment from reality that is entirely normal, even typical. In all walks of life.
What I still find surprising, even though normal, is how technical people can push actual facts and evidence right out of their world view.
Sure, 70% of the bugs in C++ code bases are memory rated according to multiple sources. So let me aggressively and confidently berate this idiot that says the Rust compiler is doing something useful.
You do not have to use either language to see how idiotic this is. Even if you accept that this guy has “the skill” to make compiler help redundant, he has no point at all unless he thinks that “typical” C++ users have that same level of skill. And, provably and trivially researched—they do not. Being this wrong makes him, as self-evidenced, incompetent by definition.
All he proves in the end is that he is angry (and I guess not a fan of Rust).
“Angry and incompetent” is sadly a much more common trope than the ones he tires off.
There's some weird effects with language-specific bug rates.
In old Java, most uncaught exceptions are NullpointerExceptions, because most other exceptions used to be checked. Can't not catch a checked exception.
So they made Kotlin, where NullpointerExceptions are the only type of checked exceptions. Now there are no unhandled NPEs anymore but now you get tons of other exceptions.
Oh yes, it's so very human nature. But damn.
Most coders get the message at least a bit, I think. Other engineers have a reputation for massive egotism, software engineers don't really.
Other engineers have a reputation for massive egotism, software engineers don’t really.
That's a joke right?
Well, it's possible I'm missing something, or that there's a different reputation actually in the industry, since I'm an amateur. The first stereotypes I think of are unkempt, caffeine-dependent and socially inept.
When I've seen people asking for help online, traditional engineers seem much more likely to flex their credentials and then not actually answer. Although there's definitely software examples as well.
"So does skill" I agree 100%
However, we're human. You show me a skilled developer who never causes bugs, and I'll show you a liar.
No matter how skilled or experienced a developer is, they always have the capacity to introduce a bug by accident.
Whether it's a typo, or simply being tired or distracted, or just having one of those moments, or even one of those days. It's completely normal.
Coding is just communication, and when working on larger codebases it can be just as nuanced as interpersonal communication. People miscommunicate every second of the day.
I've never used Rust.
