Meanwhile, Rust punches you in the face for the mere suggestion. Again. And again.

Python happily nods, runs it one page at a time, very slowly, randomly handing things off to a C person standing to the side, then returns a long poem. You wanted a number.

Assembly does no checking, and reality around you tears from an access violation.

EDIT: Oh, and the CUDA/PyTorch person is holding a vacuum sucking money from your wallet, with a long hose running to Jensen Huang's kitchen.

Rust just keeps telling me "you didn't actually learn how references work" over and over

I refuse to believe the python one ever happens. Unless you are importing libraries you don't understand, and refuse to read the documentation for, I don't see how a string could magically appear from numeric types.

[–] [email protected] 4 points 4 days ago (1 children)

You don't see how type mismatch errors can happen in a dynamically-typed language? Then why do they happen all the time? Hell, I literally had a Python CLI tool crash with a TypeError last week.

[–] [email protected] 3 points 4 days ago (1 children)

That's not what I'm saying at all. What I'm trying to say is that I can't think of any way a program working with numeric types could start outputting string types. I could maybe believe a calculator program that disables exceptions could do that, but even then, who would do that?

[–] [email protected] 2 points 3 days ago

The point of the joke is not that the Python interpreter will change types mid-program on its own, but that you don't have any real way of knowing if you're going to get the type you expect.

Programs are messy and complicated, and data might flow through many different systems before finally being used for output. It can and often does happen that one of those systems does not behave as expected, and you get bugs where one type is expected but another is used in actuality.

Yes, most likely what would happen in Python is a TypeError, not actual output, but it was pretty clearly minor hyperbole for the sake of the joke.

Am I bad at programming?

No, it’s the language thats wrong.

[–] [email protected] 95 points 6 days ago (11 children)

Except that many other languages have proven that C++ is simply terrible at providing meaningful errors.

I mean, this is correct in many cases, unironically.

It should be one of the core purposes of a programming language to help humans to write the code they intend. If a language doesnt do that then it's bad.

This is why I will never touch Javascript again. Long ago when I worked on web stuff, half my workflow was spent in the debugger tracing garbage to find where a typo was. The industry moved to Typescript, and now assuming the strictness checks are enabled, if some Typescript transpiles successfully, I can be 95% sure whatever fuckup I observe at runtime is a logic problem.

Weakly typed languages were an awful idea. But in general, if the compiler isn't able to detect most runtime issues (like with C++ here), it's not going to be the most productive language to use for building solutions compared to smarter alternatives.

[–] [email protected] 9 points 6 days ago (3 children)

I've thought about moving to typescript. Do you have suggestions for a 20+ year JavaScript dev?

[–] [email protected] 17 points 6 days ago

Try porting a very small bit of behavior into a new tiny library or module that is Typescript based and independently published. Enable the strictness checks in tsconfig - really, really resist the urge to use any, and enforce that any is disallowed in tsconfig. Familiarize yourself with its utility types that really trip new authors up. "Record" comes to mind here, and others that involve generics if you haven't before worked with generics. Some of the type error messaging can be pretty obtuse - don't be afraid to paste them into an LLM (or use Copilot enhanced Intellisense) to explain what it actually means. IMO the type violation messaging is a weak dev experience point for new authors, so don't sweat it if you occasionally "struggle to make the squiggles go away".

Ah, C++. An endless supply of footguns where the difference between a junior and a senior dev is knowing what parts of the language to never use.

[–] [email protected] 28 points 6 days ago (2 children)

Real C++ programmers pass by const ref and tell pointers to fuck off.

[–] [email protected] 17 points 6 days ago* (last edited 6 days ago) (4 children)

You can also make everything a smart pointer and be done with it.

I can count on more than one hand the number of large scale projects where converting everything to smart pointers fixed major memory issues. Even if smart pointers can’t handle circular references, the number of projects that just don’t manage their memory correctly at all and were fixed by introducing these tools is way too high.

So? Do you really expect the compiler to UNDERSTAND the code?

Here is a grammatically correct phrase for you to think:

Compilers don't paint tangential apostrophes unless the storm value is deeper than radish. Fraggles love radish.

[–] [email protected] 46 points 6 days ago (5 children)

This is something that Rust is specifically designed to prevent.

[–] [email protected] 10 points 6 days ago

C/C++ is mildly obsolete now, basically. Breaking the memory model is not really a small defect that's a matter of taste.

[–] [email protected] 10 points 6 days ago (3 children)

Prevent what? UNDERSTANDING the code?

Yeah, Rust is quite successful in that :)

Congratulations, you've illustrated the difference between syntax and semantics. But any competent compiler also handles semantics (just in a separate phase of compilation), because that's necessary for any useful conversion to machine code, not to mention optimizations.

Typescript on the other hand: Exwuse me sir, you seem to have a little oopsie right here. Oh right! Let me just fix that right up.

HERE ARE TWO THOUSAND ERRORS! YOUR PUNY LITTLE BUFFER CAN'T EVEN SCROLL BACK TO READ THEM ALL! AND YOU CALL YOURSELF A PROGRAMMER?

Just me or is the single speech bubble loop in the 4th panel weird?

[–] [email protected] 23 points 6 days ago

Very. It's like they're both saying it in unison.

What surprised me the most was the speed of the compilation, must be a very small program. I tried to compile Godot from source once. Force-stopped it after 3 hours

[–] [email protected] 42 points 6 days ago

There's a reason the play is called waiting for Godot

[–] [email protected] 10 points 6 days ago (4 children)

How many cores do you have and what compiler was it ? Also RAM can help with huge codebases iirc. When I was working with UE5 I had the best Ryzen available with 128 Go of RAM, could compile the engine (which is much bigger than Godot) from source in less than 2 hours iirc (yes that is a full clean+rebuild, not just compiling recent changes)

Is C++ the first enemy that managed to win against one punch man?

[–] [email protected] 4 points 4 days ago

I once wrote bind_front() and move_only_function likes in C++17. This nearly drove me mad because you cannot refer to a overload set by a name.

On the otherhand, I can now decipher the template error mess that the (g++) C++ compiler spews out.

I mean, the comic is fine I guess, but if it implies the Cpp lady is hitting you, it's not. That would be the kernel, the lady did what you told her to do.

[–] [email protected] 14 points 6 days ago

If undefined behavior is triggered anywhere in the program, then it is allowed by the standard for the process to ask the anthropomorphized compiler to punch you.

100% based and standards-compliant comic
