how is memory shared between threads? most of my experience with concurrency is with golang and in go there are channels and also mutexes etc, but in other languages, which doesn't have mechanism like channels, are mutex the standard way to do what is usually accomplished by channels, in go i still use mutex for things like global maps, slices etc, but some things i just don't know how could be done without buffered channels, what i want to ask is how do languages other than golang accomplish things that usually require channels, select etc.

>>92166439
idk, some problems probably have solutions using other primitives, but in cases where a channel is the right tool you can just write one if the language doesn't provide one. as far as I can tell go channels are based on mutexes too, so it's not like channels are that fundamental.

>>92166521

the reason for them to be primitives in go is very ideological, go really wanted to push concurrency and multithreading as its foundational paradigm

When learning, at what point do you look up a solution and work backwards to understand it after trying and failing to come up with your own? I want to work my brain to build a solution but at the same time I don't want to waste many hours on something that might not be that important long term.

Almost finished my 2nd hash table implementation.
It's separate chaining except that it uses a single array of struct HashEntry instead of an array of linked list of HashEntry, both because of cache locality and for avoiding using malloc each time a new entry is inserted.
Also only one function is used to found hash entries by insert(), lookup(), delete(), rehash(), etc..

The hashing function is probably shit/imcomplete though. Do you know good hashing functions? And do you need to add a big prime number at the end for randomization? I'm not concerned about security, it's just to have a good hashing function that minimizes collisions.

int hashing_function(char *string) {
    int hash = 0;
    int i;
    for (i = 0; string[i] != '\0'; i++) {
/*         hash = hash*33 + string[i]; */
        hash += (hash << 5) + string[i];
    }
    return hash;
}

I should have precised that this particular hash table library I'm making is for an interpreter/langugae so most of the time you really need to hash strings. I will make another hash table for the case where you can use pointers as key though, that's the plan.

Question: in C, if I initialize a variable in one source file, how can I access that same variable in another source file?
In a little game I'm making, I have the textures initialized (reading .jpg files from another folder) along with the window, renderer, etc, in a file called init.c. So I want to access those same textures in another file which handles the main game loop called game.c. Although I can declare the textures as extern variables in a shared header file, and game.c recognizes it (as can be seen from the lack of a compiler error), they're empty. So it looks like that isn't the solution.
I could pass the textures to the main game function as arguments, but I think that'd make it look sloppy and I want to avoid it. Surely there's a way to simply access a variable initialized in another file, probably by using pointers somehow. I could pass the textures to the game function as arguments, but I think that'd look sloppy and I'd like to avoid it. Does anyone here know of a solution to this problem?

For function calls only.
Otherwise there is C style block syntax for control flow, unary prefix/postfix and binary infix operators for expressions and finally, some additional syntax for regex/pattern matching/tree searching (one and the same).
See? Much better.

I guess this would normally work, especially since I stopped getting compiler errors when I did it, but it looks like the graphics library I'm using (SDL2) has some nuances that I'm not fully aware of, so I'll have to find another solution.
>>92172626
Fair enough. I think my idea of initializing all the textures in a single file, along with the renderer, was bad in the first place. I think I'll initialize them in game.c instead, in a separate function.
My first jury-rigged solution was to initialize the textures in the main game loop, but that crashed my computer because it'd keep defining and clearing a bunch of different textures every time the loop run (lol).

turn debug symbols on (-g), and it should tell you where exactly in your code the segfault happened.

-fsanitize=address for memory and other checks like memory leaks on linux (use the enviroment variable "ASAN_OPTIONS=detect_leaks=0" if you are using a library that causes a memory leak which is a false positive).
Also debuggers are very important, using an IDE like vscode you can use the gdb debugger (you don't need to use cmake or anything, you just need to make a folder with a folder called .vscode and it should have settings.json and inside that json folder you can specify the executable and parameters you want to pass to it, and in vscode you just need to press the debug button, you can also debug core dumps in vscode's debugger as well (you need to find the settings.json for that one).
Pretty much every vscode tutorial has a settings.json for a debugger, just ignore the cmake part.

Yes, but I have to admit I've never been a great programmer.

I would paste some code here but deleted what I was working on out of frustration.
The other source code files I have are just, random examples in where I try to apply some stuff, like in the screenshot I shared in my first reply.

>>92174635
so what are you having difficulty with

>>92174550
forgot to mention, with a debugger you can use breakpoints, which basically lets you pause the program and inspect the variables while stepping over lines, stepping into functions (enter function frame), and stepping out of functions (leaving function frame).
You can also hover your mouse over variables to get their values, see a variable list which you can expand the contents of structures, and you have a debug prompt so you can type in global variables so you can print their contents, and I think you could even call functions arbitrarily (I rarely do this).
The annoying part is that ASAN and UBSAN will block your debugger's abillity to debug, but generally you have all the information needed to break to a early position so you can step through the code and see what odd variables you have.

i'd maybe write that parse so it returned a Result<Self> instead of asserting, or an option if you don't feel like dealing with error types

the for loop can be something like this. you might also want to check the length of the source byte iter being 8 by doing source_byte_iter.clone().count() == 8 or use a counter and regular for loop

for (id, src) in id_bytes.iter_mut().zip(source_byte_iter) {
    *id = src;

would it be better to use .reset() in this smart pointer /dpt/ ?

is it preferable to keep a file open, or would closing and opening at need be better?
like, does 7z have the zip file open for the whole duration of the program or does it open to read the file entries, then closes it and whenever you choose to extract a file it reopens the zip and takes out the file?

>>92176312
Weverything probably also enables Wconversion which conflicts with undefined behavior sanitizer.
The only way to suppress Wconversion warnings is to put it into a cast, but the cast will suppress undefined behavior errors (like overflowing and signed integer due to narrowing).
Personally I like having implicit cast warnings, but I don't use the compiler warnings, I use clang-tidy and use NOLINTNEXTLINE(bugprone-narrowing-conversions) for every time I implicitly cast a number (because diagnostic suppression pragmas are worse) and I want undefined behavior sanitizer to be triggered some sort of overflow or underflow.
I also enable individual flags for both gcc and clang using cmake's CHECK_CXX_COMPILER_FLAG macro (but you need to write your own caching function for it).

If I initialize a variable in a function, how can I access that same variable with the same value in another function? Pointers?

I've only ever made CLI programs but I want to make a GUI one. I'm not going to make it from scratch so I guess I'll use a GUI library. Can you just slap any arbitrary GUI out there onto your code, or at least with minimal adjustment? Or do you have to start a program with the intention of tailoring it to a specific one?

>>92180022
Which proglang? And not even trying to meme but if you're OK with guiding ChatGPT through some prompts and showing it your API/code it will make a pretty workable GUI for you to use as a base because 90% of GUI work is boilerplate and ChatGPT excels at boring boilerplate. As long as your CLI programs aren't super fucking complex like ffmpeg or some shit.

>>92180022
>Can you just slap any arbitrary GUI out there onto your code, or at least with minimal adjustment
yes and no
first of all libraries only work with specific languages, so if you're making your program in C++ you can't use WPF for example
then, each GUI framework has its own way of doing things, so you should at least be somewhat familiar with it
for example Qt is pretty straightforward with signals and slots, WPF uses model view viewmodel, electron uses any of the javascript UI frameworks like react, etc
you could in theory ignore that, but it's going to be painful because those GUIs are designed with those patterns in mind

Can I have a null pointer key in my hash table?

ht_set(t, NULL, val);

How do I implement this

>>92180061
>>92180090
I was thinking of starting off with some baby simple program you could quickly replicate in any language and slap a GUI on just to get my feet wet. I've got one where it gives you an easy addition problem and you just type the answer and hit enter, then it tells you correct/wrong and moves on to the next. How come I can't just make a GUI in any language with a text box for the prompt/results and a field to enter the answer into, then just pipe the data between the window and the program that handles the actual logic?

>>92180297
if you want
presumably null is its own distinct value
this implies you can't use null as a sentinel

>>92180022
>Can you just slap any arbitrary GUI out there onto your code, or at least with minimal adjustment? Or do you have to start a program with the intention of tailoring it to a specific one?
Unironically MVC.
Mixing the reporting/logging/graphics code with the logic of your program makes for shit code.
Both because it will be hard to modify the logging part and because you won't be able to use your library elsewhere and will have to rewrite it but without the logging part.

>>92180022
depends on the library
Qt, the library the other anon mentioned, needs to run a precompiler called the moc as it has language extensions to make gui programming easier
so it's easier to work with if you're using a build system that supports it, like msbuild (with a VS extension), cmake, or Qt's own project system

other libraries are more simple, for example this is an example using tgui https://tgui.eu/tutorials/0.9/sdl-backend/

oh and if you're on windows and using C or C++ you need to set the subsystem to windowed and manually specify that it uses main() or else the console window will still pop up
you can do it in source code via

#pragma comment(linker, "/SUBSYSTEM:Windows")
#pragma comment(linker, "/ENTRY:mainCRTStartup")

>>92180298
you can, there's nothing stopping you aside from figuring out how to launch both seamlessly which is a pain

>>92180298
>How come I can't just make a GUI in any language with a text box for the prompt/results and a field to enter the answer into, then just pipe the data between the window and the program that handles the actual logic?
the short answer is that interop between languages is a very hairy topic, and even though it's not completely impossible, it's ridiculously complex and definitely not a beginner's project
some languages have bindings to other languages, which makes this interop a big less painful, but it's still hard

sort of?
text data is probably safe-ish, not sure about how different languages handle binary IO from the standard streams
at least on windows, you have to be careful of things like automatic locale conversion
for example i think C# uses utf-16 by default while c++ reads/writes in whatever the current locale is if you're using cin/cout or "wide characters" (utf-16 on windows/utf-32 on linux) if you're using wcin/wcout
if you just want something simple manually sending commands would be fine, but for a robust solution for something like piping function calls in-between programs you'd probably want to use some sort of library that adds support for a text-based RPC (remote procedure call) framework like jsonrpc
as for the OS "closeness" the process loader, at least on windows, does allocate the standard input handles, but there's a fair amount of abstraction over those depending on the language and the runtime

you also could use a pipe instead of just the standard streams, both linux and windows support anonymous and named pipes, although they work somewhat differently on each
or you could use a local socket, either a normal one, or both windows (10+) and linux support unix domain sockets which are meant for interprocess communication
the advantage of this is it would be very easy to make your backend run over the network and you'd be able to use normal RPC frameworks

It is somewhat reasonable to require top level definitions to have type annotations, because it's considered a best practice among functional language users even if it isn't usually necessary.

sum (a : int) (b : int) = a + b

For decent type inference with polymorphism etc. you should already have some constraint solving machinery implemented, and it's trivial to use that to solve type inference for recursive definitions (aside from polymorphic recursion).

There is no iterator. [ID_LOC..] gives a slice (panicking if out of range), [0..8] gives a pointer to an array, .* dereferences it, copying if needed.

data[start..=end]

>>92172868

You can just use a slice, which you can then convert to a regular array using try_into (which fails if the length doesn't match). So:

// this also makes the assert redundant
let id_bytes = data[STEAM_ID_LOCATION..][..8].try_into().unwrap();

true, the chain of how that shit got """"reviewed"""" and accepted with no tests and just managers saying LGTM is hopefully opening peoples' eyes to the quality of work and developers there

How can updooters justify their position when companies introduce bugs so often?

But there's an 8 right there! The compiler should know!

Zig's comptime just makes sense.

Software developers are mostly incompetent in regards of logical and analytical thinking, for the lack of a better term...
They can make an update to fix 1 bug, and then introduce 10 new bugs, that's why I try to keep my programs small in size.
It's easier to catch bugs, and I try not to share my more serious project, until they're finished, I share only toy or mock ones.

Back in the day, 90% of programs were published when they were finished (in most cases). Today it's reversed, 10% are finished.
I don't idolize Johnatan Blows, but he was half-right about his presentation "Preventing the Collapse of a Civilization".

Yes, as I said, there's 105 files there, and more in other folders, I'm messy, but only 30-ish different game engines. I don't use Git. (:

I don't want to be a dumbass anymore. Where can I find courses that provides solutions and explanations to DSA problem like these so I can grind? I failed my algorithm class and then my data structure class a year ago, and now I suffer from it by spending my weekends preparing for mid exam in April and final exam in July. I'm currently on an internship every Monday to Friday and I commute to office as early as 5 and got home at 19.30. I just need to get this over with.

If Zig can use its comptime to determine that the length of the slice is static and convert it to an array as a safe no-op then that's pretty good. Rust isn't quite there yet since it's const generics are still too primitive to support e.g. getting an array reference from a slice made using a const range with the length of that range.

i think he was totally right

>>92182812
My point wasn't "i shat out a lot of code", stop being so retarded.

>>92183257
Yeah x[i..j] where i and j are comptime known isn't even a slice, it's a pointer to an array (which can implicitly convert into a slice if needed). Comptime known isn't just literals, but quite a lot of things, including const decls.

Explains everything lmao

>>92183298
Half of that talk was supposed to be (in my opinion) dedicated to faults of von Neumann architecture and lacking of other alternatives that would resemble Data Flow or strictly incorporate general immutability into hardware directly.
I suggest you read John Backus's paper on von Neumman languages, if you already agree with Johnatan Blows. It'll give you a great insight into programming language structure, design and parsing.

>>92183254
>first one
Think about it brute force first, you just need to arr[0] - arr[1], then arr[1] - arr[2], then arr[2] - arr[3], and whatever number appears twice is your pattern.
Now just figure out an 0 N solution where you can iterate through the entire array, while looking for number that is i-1 + (2 * pattern).

You just need to stop letting your brain tell you something is way harder than it looks.

>>92183337
> Explains everything lmao
Explain...
Yes, I don't use Git, it's a bad piece of software, and a bad practice in my opinion, because "software developers" (text typing people) are encouraged to just make new changes, and if it compiles, it's good.
Not many people write in Ada programming language (I do), or use Splint and Valgrind when developing ANSI C programs. Most of them don't even enable all compiler warnings, I do.

>>92183392
>new changes, and if it compiles, it's good.
You are absolutely insane if you thin that modern devs don't leverage automated test so that they aren't just adding changes that create more bugs.

>>92183428
Are you aware of how many programs have tons and tons of glitches, bugs, and crashing errors?
And no, Pust, automated tests, OOP, TDD, whatever else next they "invent" won't change that.
You can't replace a smart programmer with a paradigm or a set of rules to follow to "correctness".

welp, back to writing algo/find/sort/memory-layout stuff

better yet, I'm going to take a friggin nap, it is 2:45 AM after all.

That has nothing to do with Git, retard.

Yet you use Ada..?

Is there a better/non-unsafe way to read in raw data to a str in Rust?

>>92183515
> That has nothing to do with Git, retard.
It is my opinion that systems like Git encourages it as I said. Don't share unfinished programs.
> Yet you use Ada..?
Yes, and Ada is 5% of my projects, I use C for 90%, which is the majority, and 5% other languages.

Up at 1AM after sifting through nonsensical java framework documentation where every version deprecates a previous version's annotations and methods. Also started work on a personal project to move an old game that has to be compiled with VS6.0 to work with Cmake and eventually work with SDL for cross platform purposes. There's already something that does this but its ran by retards that break everything and make the game less stable than it was 10 years ago.

How else is a team supposed to collaborate on software development?

you are confusing git with github and it is making you look very very very stupid

>>92183564
Just don't use the unchecked variant...

>>92183564
ignore the if statement there, the code in the else clause I experimented with is useless and doesn't work

>>92183428
>aren't just adding changes that create more bugs
look around

>>92183564
what do you mean raw data? you might want to be using osstr/osstring or vec<u8> then write it to stdout after as bytes or convert it. the string lossy methods are useful
https://doc.rust-lang.org/stable/std/?search=lossy

that err function is weird. i recommend some kind of try_main and main so you don't have to do that and can just bubble up

fn main() {
    if let Err(e) = try_main() {
        eprintln!("{e}");
        std::process::exit(1);
    }
}

fn try_main() -> Result<(), Box<dyn std::error::Error>> {
    Ok(())
}

>>92183628
No it panics if the file isn't UTF-8. I'm trying to read in binary data.

>>92183564
>unwrap_or_else(err)
the very same people moaning about go result handling

>>92183652
Strings in Rust have to be valid UTF-8. If you're dealing with arbitrary data then you have to use arrays/slices/vectors of bytes (u8).

>>92183648
Oh thanks, I'll look into osstr

>>92183652
i can't tell what you mean, do you know about files? you can use OpenOptions to build and open a file
https://doc.rust-lang.org/stable/std/fs/struct.OpenOptions.html

>>92183676
I actually like Go error handling, I think it's simple and nice

>>92183615
Don't collaborate online with friends or strangers, open source has failed with the inclusion of Pust into Linux, and HURD not being finished.
Blender, GIMP and many other good (usable) programs are bad because they're cross-platform.
>>92183627
No, when I say Git, I mean on GitHub, GitLab and stuff that's using Git, in order to keep it shorter, don't cherry-pick.
If you're not sure what I meant (which was obvious), they kindly ask?

I give up, this is beyond irredeemable, I'll go write programs...

>>92183107
All the languages with the worst compile time, how nice.

>>92167435
Wow, this looks useful.
Always disregarded property() since I don't need encapsulation. But moving conditional statements into the attribute saves me from typing it out in every function.

>>92183799
>I don't need encapsulation. But moving conditional statements into the attribute saves me from typing it out in every function.
Bro, that's exactly the kind of thing encapsulation is for.

People with mental illness developing (any)thing.
You spend more time reading than writing programs.
Good thing is, C and C++ people got rid of them! (:

>>92183890
Guess I skim over things too much then. Should probably read up on the other builtins and see if there's more I missed.

Sometimes I wish you'd post less.

>I give up, this is beyond irredeemable, I'll go write programs...
I think that would be the best thing for everyone.

>>92183930
>why is it so ugly?
Because they fucked up strings. They thought it was easy, when no, it isn't. Now they've got to live with their mistakes, and the result is terrible.

>>92184184
No they didn’t. They have a different string for every possible use case. C fucked up strings and gets railed on about it eternally, deservedly too.
