Trying to learn OpenGL for like the fifth time this week. I got everything up and running and am following this tutorial -> http://www.learnopengl.com/#!Getting-started/Hello-Window

I'm about a third into the actual code, but when I run it, I get this monstrosity of an error message...

['Kc', '10c', 'Ac', 'Ah', 'Jc']
royal flush
['9h', 'Qd']
['5h', '7h', '6d', '6h', '8h']
straight flush

i think the math is about right. i simulated 30,000 hands ealirer. it took about 6 seconds and found quite a few straight flushes and a few royal flushes. i'll have to actually look at poker odds and test my engine to see if it aligns.

I need to remove duplicates from several lists that I'm filling with data from a SQL database in C#. Google search/MSDN says I can instantiate a new empty list and just fill it with the old one using

.Distinct().ToList();

, but where can I read about novice algorithms for this kind of thing? Would it be time to break open CLRS or Sedgwick? I don't want to use it without being able to do at least a version of it myself.

>>58304502
>being autistic

Yo people, I'm working a checkers game for a school project, and right now i'm stuck at trying to import and image with JavaFX.

 public void titleView(Pane pane)
{
    Image img = new Image("file:test.png");

    ImageView title = new ImageView(img);
    title.setImage(img);
    title.setLayoutX(569);
    title.setLayoutY(146);
    title.fitHeightProperty().add(100);
    title.fitWidthProperty().add(100);
    title.setVisible(true);

    pane.getChildren().add(title);

    System.out.println("success!!!");        
}

What i'm looking to do, is being able to package the test.png with the jar files when i make it a runnable program, all the variations of filenames/filepaths leads to me getting a null pointer exception. I can't for the life of me figure out where to put the image and how to refer to it in order to use it. Anyone got experience doing that?

only started coding once python3 was already out.

when i was 'trying' to build my bit torrent client i ran into a few problems but most of it was just syntax stuff. also some other stuff i coded they changed a lot of libraries for instace like urllib.quote.parse or something to that effect used to just be urrlib.parse so it's like naming of things or something?

>>58304565

>if you want to waste time memorizing and poorly re-implementing algorithms maybe for interviews stick to sorts, those are the real boring ones
Cool. I didn't want to go full pajeet and just blindly use distinct() because SO/the internet said so but I'll just use it and deal.

>distinct() and the algorithm in question in general is about 4 lines long and in O(n)
Is it really a linear search?

>>58304504
yes there is. after 5 lines of code you start to see real differences. you're generalizing over something less complex than hello world

>>58304495
Use a Set, they guarantee no duplicates (as long as you don't care about order)

There's no need to use lower-level logic to do inefficiently what data structures can do for you efficiently.

>>58304903
C# has a HashSet, which is the closest it comes to Python's set (which I think is what you're referencing). Like I said, I'm just using distinct() and dealing with it since it does the job and I'm not hitting numbers of items that would require putting things into a HashSet yet.

How do I match a list using guards in Haskell?

Say I have a function multAll that needs to multiply all numbers in the list.
Using pattern matching it would be

multAll [] = 1
multAll (h:t) = h * multAll t

but I have no idea how to write it using guards.

This thread is pathetic. It is not about programming. It's just a bunch of computers illiterates and first semesters memeing about whatever they just learned.

A quick search shows that most arguments used here are not original and have been copied from some trendy tech blog or other shit site.

The only real programming questions I have seen so far are from beginners(it's fine to be a beginner btw).

This entire site is shit and I don't know why anyone would regularly come here.

It also looks cool. That one sturdy line, and that sleek elegant curve. It's just a pleasant looking letter.

Does anyone know why the first and second Python code block produce different output?

word = "Germany.[13]"
print(word)
word = word.strip("[")
word = word.strip("]")
print(word)

This prints:
Germany.[13]
Germany.[13

word = "abcde"
print(word)
word = word.strip("a")
word = word.strip("e")
print(word)

This prints:

Why is mechanical keyboard and multiple monitors in """sarcastic"""" quotes?

Your fingers are much less tired after typing on mechanical keyboards, and you are more productive with multiple monitors. Especially if you have one you can rotate.

I realize that it seems weird that you're using URI and checking with toURL, but it's a good habit to get into.

And they're not that expensive. I used to wear out two keyboards a year before I got my mechanical one, that's lasted for three years already. It wasn't 6 times as expensive, so I've saved money on the whole.

And I don't shitpost at work. (I do keep tabs open at the DPT and WDG threads though. Those threads sometimes have relevant information.)

What can be considered as basic knowledge of C? For example to be accepted as junior programmer. How do I evaluate my skills?

I am trying to use the terminal to run C++ programs now, so I wrote a simple one implementing a menu as a switch function. However, it's only allowing me to choose once from the menu instead of continuously as I remember it doing before. Here's the relevant snippet of code:

cin >> choice;
switch(choice) {
case 1:
  p1.draw(d);
  break;
case 2:
  p2.draw(d);
  break;
case 3:
  d.check_remaining();
}
cin.get();

Any ideas?

You really shouldn't use this as a point against Vim or Emacs. Sublime supports Windows, Mac OS X, and x86 Linux. Vim and Emacs work everywhere.

>Implying a dependency on Linux
They work on every *nix system under the sun (not just Linux) on every single instruction set (Sublime ONLY does x86), and also work on Windows. There are also ports to more obscure and/or defunct non-Unix OSes like Amiga OS 4 and OS/2 Warp. There are no editors with better portability than Vim or Emacs, period.

There is a point to be made about Sublime having a lower learning curve and a lot more features out of the box. But don't pretend it's something it's not.

Let me get this straight:

I only need to free data I've malloc'd myself, right?

But if I want a function to return something like a struct back to its parent, I have to use malloc, or else that struct memory will automatically be free'd when the function terminates?

>>58307731

>and experience was terrible
A port is still a port, even if it runs like ass. Although the version of Vim that comes with MSYS seems fine to me.

And for what it's worth, I also tend to prefer Sublime. I'm just correcting a terrible claim about Sublime's portability.

>>58307763
If you're returning a reference to a struct you allocated to the heap, I gather the code that called your function is responsible for freeing it.

Hey guys, I'm looking for a single-file virtual file system format.. like a zip file or something. But I want to be able to edit, delete and extend files in it, but do so with the least amount of read.writes. I might be dealing with gigabyte files, and i might only want to extend a single 5mb file inside. I don't want to have to write an entire new file to the end of the zip file etc.

Can't seem to find what I'm looking for though... Anyone have any ideas?

>>58307763

>I only need to free data I've malloc'd myself, right?
Any data allocated via malloc must be freed before the pointer voes out of scope, or you will leak memory. This is true whether or not you malloc it or a library function does it. That said, if the library has a custom deallocator function, you should always use that.

>But if I want a function to return something like a struct back to its parent, I have to use malloc, or else that struct memory will automatically be free'd when the function terminates?
No. There are a few ways to deal with returning structs.

1. Return pointer to struct as you suggest. This is how things are typically done with opaque structs.
2. Return struct by value. This is well-defined behavior, and is not equivalent to returning pointers to stack objects (which is always a bad idea).
3. Don't return it, but instead, pass a pointer to the struct as an argument, and have it initialized in the function. This should be the preferred method of dealing with struct initialization, as it allows the caller to choose between stack and heap allocation depending on which is appropriate for the situation.

We're bioinfomaticians and biologists in our group often needed a certain type of analysis from us. We used to get the request from them, run the pipeline (took several hours), then send them the results/put them on our server.

With this they can run their own damn analysis from a web interface (yet to be created - I might try to push that on someone else...) and fiddle with the parameters on their own.

Yes.. all of whom would benefit wildly from lowered corporate tax. Did you think about what typed said before you posted it?

STL? Templates? Lambda functions?

I know the STL is too bloated, templates are ugly meta-programming and slow down compilation. But standard C still doesn't have anonymous functions and these are invaluable for those who use them smartly, especially with generic lambdas (from C++14 on). Basically, you could replace every template with a lambda and get both compile-time and run-time benefits from them. And conciseness in code too.

Incompetent one, though.

Keep in mind that what you don't use, doesn't get included in your program. That is the nature of templates.

>templates are ugly meta-programming and slow down compilation.
Would you rather spend more time writing code or compiling code? When your computer is compiling, you can at least spend your time doing other things.

Templates and lambdas solve completely different classes of problems.

pretty cool

Very interesting anon. I'm working on a somewhat similar project, a programming language for malware development. It's based on racket and not very different. The main features I implemented so far are payload encryption, polymorphic code and some functions on the standard lib that make process hiding easier and abstracts the OS.
I don't think it's ready to be published yet.
