Reposting because i'm a retard who posted in a dead thread.

Alright, I did a shitpost detector that attributes a grade to each post in Python. I want to do a web extension for this, which would basically put a little icon next to the name of the poster depending on how shitposty the post is.
How would I go on to do that ?
Also you got bad grades anon. I'm gonna have a little talk with your parents on how you discuss with people on this South Vietnamese rice farming forum.

How would I correct the error in the image?
Also, how would I fill the hashset with the amount of objects using a loop?
And how would I also set each element of an arraylist to be assigned with another object?

It probably is, but I don't know tits about web dev. I'll take a look into it, just need some ideas on where to start.

The algorithm is pretty simple, it checks for length, amount of curse word, number of replies and if the replies says thanks. Then it add the grade of each of those attributes into one. I'll refine it once i'm done with the web implementation. I'll also set up a repo so you guys can check out my abhorrent coding skills.

I could write a whole book about this. Well not me, but someone else as I suck at security and rely on other libraries

The basic concept is
> generate a long unique string (20 characters is definitely enough)
> add it to the front of the password
> use sha512 or some other modern hashing function like sha3 on the string you just created
> store the output and the string you created
> repeat the process each time the user logs in

That being said, Google has plenty of libraries that let you use their authentication system. But if you still want to do it, make sure all of this is in the server side, but client side

For freetype, but I suppose it applies to libraries in general. Are you supposed to link debug builds of libraries in your own debug builds and link release builds of the lib in your own release builds, or just have one release build of the lib and link that wherever?

>>57827800
>How do you handle hash collision in ten lines of code?
Depends on how you want to deal with it.
>GLib
Well as far as libraries go it seems ok. It's not using std::pair as the C++ std library does. How a standard library can be that sloppy is beyond me. So I approve of this library.

But a major problem with practically any library is how you introduce all these new types to deal with. It clutters your brain space. When you write things yourself you get exactly what you want and it's very easy to extend if you need to.
You're not gonna do something very fancy wish a hashmap usually but in the general case you may want to have a smaller piece of code to work with.

If you don't it's not rare to end up in a situation where you don't exactly feel the exact implementation is all that appropriate and you work around it, rather than changing the library you've been using. Simply because you can't be 100% sure of how it works before you start reading everything. Just looking at Glibs hashmap there's a fairly large amount of functions I'd probably straight up delete if I decided I need to change something.

Can someone redpill me on typescript

just tried it out, and it seemed saner than straight-up javascript in pretty much every way. Well-defined way to do classes, modules etc, stricter typing (although still not nearly as strict as I'd like it to be), seems to compile to very clean javascript code (basically just your original code with types stripped out) etc

why is it not more popular? only drawback I could find so far is that the compiler seems to be rather slow, but I think that's not the worst thing ever.

>>57828532
It has some upsides and some downsides. Doing layouts like you normally see UI do (where it scales to different sizes and keep certain offset) is more of a chore.
To get something up on the screen and properly showing what you want to show is way easier.

Probably there's something I don't understand. How can OO-less system be more resource-heavy than OO-ful system?

>>57828683
>requires GPU
Well any decent GUI library does.
Software rendering isn't the cool thing to do anymore anon.

Either way it's a very small part of the system and has incredibly little to do with the actual systems at play.

I got a C++ class with template, let's say something like the following:

template <class T>
class Foo
{
    public:
        virtual T* doSomething() = 0;
};

I inherit this class like this:

class Bar: public Foo<Bar>
{
    public:
        virtual Bar* doSomething() = 0;
};

Now, if I want to have some function that accepts any child of Foo as an argument, how would I go about it? I can't for the life of me get something working.

>>57828683
>>57828719
Oh and to be clear it's just this implementation.
Imgui is broader. You can do software rendering if you so choose.

>>57828580
>Doing layouts like you normally see UI do (where it scales to different sizes and keep certain offset) is more of a chore.
People always say stuff like this but there are usually easy solutions.

>>57828683
Ah, well, IMGUI doesn't work all that well unless you have a main loop and are getting input and repainting constantly, particularly in the context of a game. It's pull-based rather than push-based.

There's also FRP but I doubt you're interested in that.

>>57828683
Not doing OO makes state a little more explicit, which can help you to boil down the state of your GUI more concisely into the absolute minimal set of state you need.

Excessive class hierachies can also impact performance, e.g. through virtual functions which have some overhead.

The difference is not really that relevant for GUI systems, and whether something is heavy or not is hardly influenced by whether it's OO or not, or immediate-mode or not. All the big serious GUI frameworks are "retained-state", the "simple" UI toolkits for games and such are sometimes immediate-mode, but it's really more of a stylistic choice.

immediate-mode is sorta easy to get started with if you just quickly want to barf a few buttons on the screen, but it becomes a completely unusable mess for anything more complex than that.

>>57828725
I sort of did this for work.
Do you want to add it to the abstract class or implementation?
What happens when you add the method declaration that you think?

Going through the well typed interpreter example, Idris is quite cool

>>57828755
Whereas RMGUI is always a completely unusable mess.

>>57828747
>IMGUI doesn't work all that well unless you have a main loop and are getting input and repainting constantly
Well that happens in OO systems too really.
It's just that they either do it in a separate thread (which you can do with imgui too) or they do it from their own state in a gui.render() call.

>>57828800
I suppose you can have it block on input, but you'll still end up repainting the whole thing every time.

Not that that should ever be particularly expensive.

>>57828725
Bar in this example should be one of the classes implementing doSomething().

I want Bar and any other children of Foo to pass as Foo-arguments. I've tried just about anything I could think of and exhausted my google-fu to the max, but haven't gotten it working yet. Starting to think it might not even be possible in C++.

>>57828798
kek, true I guess

well, it's somewhat managable. But while RM GUI systems have a higher "base-level messiness" I think they definitely scale better.

There are also some new paradigms that have recently come up like e.g. react or whatnot where state is injected at the root of a tree and then propagated downwards etc, which makes things a little more structured. Another paradigm is facebooks flyweight pattern (but I've never really looked much into it, so no idea)

>>57828725
The function should accept a pointer to Foo, or something equivalent (i.e. a reference, smart pointer etc.).

At what point can I say that I am experienced with Java on a CV?

I've never used jframe or anything, but I'm comfortable with the standard commands, and I've built games and things.

>>57828838
In the end we need to figure out an optimal way to have a mix of both, I think. Retaining state tends to be better for the presentation side of things while being immediate tends to be better for the logic side of things.

>>57828860
>I've built games and things.
Say you're experienced then. You shouldn't be punished for having high standards.

Thanks in advance

>>57828725
>>57828788 (me)
You shouldn't make the implementation methods virtual if you're going to define them.

I did both as an example:

template <class T>
class Foo
{
public:
    virtual T* doSomething() = 0;
    virtual void takeSomething(const T&) = 0;
};

class Bar : public Foo<Bar>
{
public:
    Bar* doSomething();
    void takeSomething(const Bar&);
};


Bar* Bar::doSomething()
{
    printf("Hello from Bar");
    return this;
}

void Bar::takeSomething(const Bar &)
{
    printf("Taking something");
}

>>57828901
VS Code?

>>57828880
That yields me a

> cannot convert ‘param’ (type ‘Bar**’) to type ‘Foo<Bar>**’

Pointer to pointer because that's what I need.

>>57828930
Because that's an invalid conversion.

Bar **bar;
Foo<Bar> **foo = bar; // pretend this is allowed
*foo = new Foo<Bar>(); // uh-oh!  now *bar points to a Foo<Bar>

>>57828910

If we take your code, I'd want a global function that takes any Foo child as a parameter. Something like

template<class T>
void doWhatever(Foo<T>* arg) {
//whatever
}

However, that and any variations on it have failed to compile so far.

I'm trying to sending xml like data, but without the

>>57829320
That seems to work, neat. I also discovered that changing the argument type to Foo<T> const* const* and casting my value to that also works, but your method seems shorter. Thanks!

>>57829410
The xml declaration is there so a receiving application knows how to read.
If you don't have a header the application has to guess.
>is it still valid XML
Yes. But that doesn't mean everyone handles headerless XML.

python is very good, its for gettting work done
real system are implemented on mass scale, which means individually, one should strive for python

In C, I have a server that can have loads of clients and each of those clients can have a pointer to another client

if one of the clients leaves and the server frees the resources of the client, lots of other clients now have pointers that are now pointing at unallocated memory

how would I go about preventing this?
should I do a smart-pointer type thing and have reference counts?

You could just overload the function to take foo and bar, and any further children of foo, as inputs. If the function is big, just extract the information you need in the overloaded function, then have every overloaded function call the same smaller function.

/g/ I'm really at a loss here

im supposed to write a program where the user refers to a text file, writes to the file, closes it, and reopens it and prints out what the user put in.

which I have done. HOWEVER I'm supposed to allow the user to enter "any amount of integers they want" which is an issue, since my program only writes the first integer.

How exactly do I allow the user to enter any amount of integers?

public static void main(String[] args) throws FileNotFoundException
   {

      BufferedReader reader = null;
      String userString = "";
      String inputFileName = "";
     
      
      Scanner console = new Scanner(System.in);
      System.out.print("Input file: ");
      inputFileName = console.next();

       Scanner in = new Scanner(new File(inputFileName)); 
  
       
       Scanner numberin = new Scanner(System.in);
       
        System.out.print("Input the numbers: ");
       userString = numberin.next();
   
 int integers = Integer.parseInt(userString);
    
       PrintWriter writer = new PrintWriter(inputFileName);
  
       writer.write(integers + "");
       
    
        writer.flush();
        writer.close();
        in.close();
        System.out.println("done");
        
        try{
        Path file = Paths.get(inputFileName);
 
        reader = new BufferedReader(new FileReader(inputFileName));
        String line;
    
        while((line = reader.readLine()) != null) {
            System.out.println(line);
        
        }
        }catch (IOException e) {
        e.printStackTrace();

      System.out.print("Input file: ");
      inputFileName = console.next();

       Scanner in = new Scanner(new File(inputFileName)); 
  
       while (true){
       Scanner input = new Scanner(System.in);
       
       System.out.print("Input the numbers: ");
       userString = input.next();
   
       int integers = Integer.parseInt(userString);
    
       PrintWriter writer = new PrintWriter(inputFileName);
  
       writer.write(integers + "");
       
    
        writer.flush();
        writer.close();
        in.close();
        System.out.println("done");
        
        try{
        Path file = Paths.get(inputFileName);
 
        reader = new BufferedReader(new FileReader(inputFileName));
        String line;
    
        while((line = reader.readLine()) != null) {
            System.out.println(line);
        
        }
        }catch (IOException e) {
        e.printStackTrace();
    }
   }
  }
 }
}

The issue is that I think I need to input all the integers and once so that the text file is full of integers and then they are all output back.

I have no idea how to do that, I think I'll probably need to do an array but I don't know how that would look.

Everyone says not to do

using namespace std;

, but all the problems that come with it (as far as I can tell, corrections welcome) are solved by just putting your whole program into a namespace, which you should be doing in the first place.

>>57832926
C++ has no value in itself so it needs to steal C's credit to stay relevant.

@57834031
c++ is literally the best. don't use it though i don't want your kind attempting to shit it up. you can stay with the .n*t and j*va plebs

>>57834043
nice C++ code.

>>57834051
i did it.
now please refrain from talking to me. i don't want your kind shitting me up.

>>57834021
They want to check if you're a normie. The place or probably riddled with SJW.

>>57834063
>i did it.
you didn't do it in C++ otherwise you'd show the proof (code)

now GTFO you memeing fagot

Did AoC day 4 parts 1 and 2. The code ended up being ugly as fuck.

>>57834072
sorry i don't do opensource
now please refrain from talking to me. i don't want your kind shitting me up.

>I can't even solve the most basic tasks with my messy meme "language"

QED

>>57834112
just did
>messy meme "language"
uh...
but i dont use java or csharp

What's the difference between the Java virtual machine thing and the .NET framework? I've never understood the concept of a framework

>>57834127
>just did
doing means posting the code

what you did is you proved that C++ totally sucks

>>57834145
not really though
i dont believe in opensourcing my code
in what way?

>>57834127
btw, you realize that in java and c# what I asked you to do is two function calls which every noob knows?

standard C++ doesn't have the most basic necessary tools to complete everyday tasks

>>57831999
LISP-2s are an abomination.

That is weird, If I save my neural network to a file and then load it it produces totally different results

>>57834166
It's sentient, you monster.

>>57834166
uh oh

>>57834166
it knows you're putting it to sleep and doesn't like it

New thread when?

>>57834200
>c++ got owned
>better start a new thread

never change /g/

>>57834208
wut?

>>57834200
Now.

>>57834213

It's okay, you can stop pretending, we all know you're gay now.

>>57834208
I just got here. I'm this guy:
>>57834163
>>57834200

>>57834251
Also I forgot to add that C++ is also an abomination.

>>57834166

MAN, WTF

It doesn't work in totally 1:1 environments and even doesn't work when I change the encoding???

New thread:

>>57834200
You fags really shouldn't ask about new threads.
It usually causes multiple people to try and we get a bunch of duplicate threads.
And if you do it early, some douche will create a new thread before the bump limit.

>>57829995
Check out Eli the computer guy, he got some nice videos on how to do well in CS related jobs.
Basically, apply anyway. You've got pretty much nothing to lose. Show them what you do, and hope for the best.

>>57829995
keep improving your coding style and learning more

btw, requirements are often just guidelines, don't let that stop you from applying where you want (also don't be a sad fag if rejected, that's also normal, just keep applying )

>>57833922
>Trying to say that OOP is any good, and that we shouldn't just stick to C.

never change, pajeet.

>>57834376
>large codebase in C

no thanks, whitey

Would this be a worthwhile feature for an IRC bot "/dpt" would make the bot post a link to the most recently made dpt thread - no idea if I could make it but would it be worth investing my time into trying?

>>57834400
You could do that in less than 2 minutes. Your life must be very short if you need to worry about such short time frame.

>>57834418
;_; it'd probably take me days if not weeks to do it I've never done anything that interacts with websites
