The point was never to illustrate capability. The point was to illustrate examples where a puristic OOP design doesn't cut it.

C++/Java lambdas/anonymous classes/functors and treating these as first class citizens and creating state capturing closures are arguably a concept derived from functional programming.

>state capturing closures
*currying

This isn't entirely true, see stackoverflow.com/a/33874965

nevermind

I'm currently taking a look at the akari-bbs source and came across some interesting syntax in the xss_sanitize function.
static const char *escape[UCHAR_MAX] = {
['\n'] = " ", /* change '\n' to '\r' */
['\"'] = """,
['\''] = "'",
[''] = ">",
['&'] = "&"
};

How exactly does this work, and is it standard syntax? Never seen something like that...

gcc.gnu.org/onlinedocs/gcc/Designated-Inits.html

Now that's a nice feature. Thanks for providing the link.

Haskell frontend for Processing.

Learning C# by implementing a simple card game.

I've shuffled the deck just fine, now I'm trying to cut the deck.

I've used this:
private Card[] Cards;
public void cutCards()
{
Card[] tempDeck = new Card[52];
Random rnd = new Random();
int randomCut = rnd.Next(0, 51);
int x = 0;
for (int i = randomCut; i < 52; i++)
{
tempDeck[x] = Cards[i];
x++;
}
for (int i = 0; i < randomCut; i++)
{
tempDeck[x] = Cards[i];
x++;
}
Cards = tempDeck;
}

But does that final "Cards = tempDeck" cause a memory leak?
Should I free the original Cards array before I assign it?

Since you're assigning Cards to a new thing I don't think you need to worry about nulling first. However I'm not an expert.

Since the array previously pointed to by Cards has no more references pointing to it, I'm sure it will get garbage collected.
From what I've read leaking memory in a garbage collected environment is not entirely impossible, but a lot more complicated than passing things around the way you do.

>"Cards = tempDeck"
is not valid syntax. You need a variable name.

Also, for some reason I'm getting 61.333fps with this. No idea what that's about.

Memory leaks can only occur when you've got a string of references somewhere where you don't expect it.
Say you've got an anonymous class: The anonymous class actually keeps the outer class from being collected, because it captures its scope. This isn't an issue, but you gotta keep in mind that as long as a small anonymous class is alive, a big outer class may be alive as well.
Trees for instance are a similar issue. Let's say you're leaking references to nodes and want to delete the tree. You null the root, thinking the GC will take care of it. However, any reference to a sub tree of the root will drag around the entire sub tree of that node reference as well, even though you didn't intend it.
There are no memory leaks in terms of forgetting to free something, but in terms of overlooking that you're still dragging around something.

>And then there is Annabelle McAllister who is raising up the dead...

Cards is a variable, not a type. See the top line.

I see. I'd prefer to manage it myself, mainly because I can't be positive that it has actually been cleaned up, but I guess just keep going until I realise there's an issue?

Or anyway I can be sure it does get freed?

float inaccuracy.

def y():
return niggerjews("y()")

;_; So jealous of programs that can run at a clean 60fps. Gonna go to bed and try to figure it out tomorrow.

Are you writing this in a language with GC?

Nah, that's C++.

I see. variables should be camelCase.

There's no memory leak because the previous values that Card had gets garbage collected.

Sorry to bother Sir but this throws the error:
NameError: name 'niggerjews' is not defined
???

So it should be "cards" for the variable name?

>variables should be camelCase.

Again the stormtard exhibits his only skill to the outside world, that of fixating on superficial exteriors and judging the book by its cover.

Your ways. Learn to follow a sentence, you dumb poltard.

I am completely serious. I want you buffoons out of the civilized internet and back in your dark caveholes.

Being poltards whose only purpose is trolling and shitposting, it's understandable that you would expect everyone else to operate under that same mental framework.

But the reality is most people aren't like you, they don't exist merely to make noise and die out, or "pee in an ocean of pee" as you might say.

>Your ways.
What exactly do you think "my ways" are?

> Everything is da jooz' fault! They are the reason I'm such a loser and have no skills other than shitposting! Yeah, they're to blame, not me!
Keep being in denial, poltard. I'm sure it has worked out so well for all your loser life.

>I want you buffoons out of the civilized internet and back in your dark caveholes
>implying Cred Forums isn't one of these dark caveholes

I disagree with Cred Forums on almost everything and I'm not even racist. You're just flinging wild accusations around and calling everyone who replies to you a stormtard.

Your ways if being a dumb racist loser NEET that has failed in life and deflects that failure onto scapegoats and people different from you.

But Cred Forums is a "dark cavehole" for people like us. Why do you think we post anonymously?

When someone calls someone "nigger" or "faggot" on Cred Forums, they are not actually referring to their skin colour or sexual orientation, you autistic fuck. They are referring to the behaviour and mannerisms of the poster. For example, the "-fag" suffix is commonly used on Cred Forums (gamerfag for example) but does not refer to homosexuals.

You're clearly acting like a newfag right now. "newfag" does not mean that you recently came out of the closet or anything, it means that you're acting like you recently discovered Cred Forums.

The whole point is to be offensive, not racist. It's just that racist slurs seems to trigger people more than anything else, like it triggered you right now.

Cred Forums and a bunch of other chans have always been this way, as a counter-movement to the online censoring and forced "safe spaces" that began online in the early 2000s.

If you don't understand that "nigger" on Cred Forums in 2016 means something else than "nigger" did in 1960, I feel bad for you.

That is literally the purpose of Cred Forums.

I never intend to go to pol, because I'm not an ignorant loser. I want to rid *this place* of you ignorant losers and make *you* go back to the place you belong, and that's why I post here, not on pol.

Why are you using @ symbol?

Not him, but can you just quote properly. The "hurr durr I'm not giving you any (You)'s" meme isn't funny and I'm having a hard time following which posts you're actually referring to.

Is this a valid use of gotos in C?
int
file_read(File *file, uint16_t *data, size_t pos, size_t size)
{
FILE *fp;
uint8_t *temp;
size_t read;

if (file == NULL || data == NULL)
return -1;

fp = fopen(file->name, "r");
if (fp == NULL)
return -1;

temp = malloc(size);
if (temp == NULL)
goto err_fclose;

fseek(fp, pos, SEEK_SET);
read = fread(temp, 1, size, fp);
if (read == 0)
{
goto err_free;
}

fclose(fp);

for (size_t i=0; i

Because he is a retard who believes typing one symbol as opposed to another will magically prevent me from getting through to his mind. Poltards are quite prone to believing in voodoo like that.

Your tirade belongs on Cred Forums, not on /dpt/. We're supposed to discuss programming, not how evil and stupid racists are.

I get that URI queries are fucking ugly, but you're not seeing or handcrafting them anyway.
On both the client and server side exist mature and well tested code bases to handle the queries, while this path bullshit has to be matched with flimsy regex:

Server - nginx:
location /api {
set_unescape_uri $arg_foo;
echo $arg_foo;
}

Client - python requests:
requests.get("doman.tld/api", params={"foo": "bar", "id": 4})

I'm sure apache and JS work in similar ways. Is it just the usual webdev faggotry "Change for the sake of change" or am I missing something?

usually you have middleware that handles the matching. most of that is pretty well tested at this point i think

Wrong. C# inherited almost all of Java's shortcomings. A completely unimaginative language.

First of all, C# is not a Java clone. In the design of C#, we looked at a lot of languages. We looked at C++, we looked at Java, at Modula 2, C, and we looked at Smalltalk. There are just so many languages that have the same core ideas that we're interested in, such as deep object-orientation, object-simplification, and so on.

One of the key differences between C# and these other languages, particularly Java, is that we tried to stay much closer to C++ in our design. C# borrows most of its operators, keywords, and statements directly from C++. We have also kept a number of language features that Java dropped. Why are there no enums in Java, for example? I mean, what's the rationale for cutting those? Enums are clearly a meaningful concept in C++. We've preserved enums in C# and made them type-safe as well. In C#, enums are not just integers. They're actually strongly typed value types that derive from System.Enum in the .NET base-class library. An enum of type "foo" is not interchangeable with an enum of type "bar" without a cast. I think that's an important difference. We've also preserved operator overloading and type conversions. Our whole structure for name spaces is much closer to C++.

pair programming what ?

Hard to tell without your computer config, the used programming language and api.

daisuki~

F# is unimaginative too.

Neither C# nor F# supports anything beyond the most simple abstractions, just like Java.

Java generics are less broken than C# generics.

The sanitizer is missing ['`'] = "`"

Just another unimaginative OOP language.

It's not just your average joe's snake oil, it's extremely snaky oil

what do you guys think of go

>Neither C# nor F# supports anything beyond the most simple abstractions
Thats true. Though more advanced langugaes have their own problems. C# is a great get-shit-done langugae as it is.

>Java generics are less broken than C# generics.
Go on..

>more advanced langugaes have their own problems
such as

Terrible language.

>C# is a great get-shit-done langugae as it is.
I find it hard to 'get shit done' when I'm constantly having to repeat myself in code.

>Go on..
Parametricity (although Java goes on to shit itself by allowing reflection)

>Hard to tell without your computer config, the used programming language and api.

HD6750, E5700, C++ and SDL2.
No OpenGL, just normal SDL2 calls.

Many programmers don't understand them therefore they're bad

what is the /dpt/-approved language/framework for website backends
you guys hate js, ruby, python, php, and java

C

Haskell

>webdev
Fuck you

JS is a front-end language and a terrible one at that. Don't ever use it on the backend. I don't care if that means you have to learn another language (oh how terrible you poor thing).

There is no good language for web development

Where can I find some programs to edi in visual studio 2015 and see how they work. I'm mostly interested in seeing how people use the desgin tab for things and how things there work.

webasm

are you rendering the same texture x 2000 ?

Nobody actually uses VS, why do you think they give it away for free?

Poorer ecosystem. Less target platforms, smaller community etc.

Yes, each x is a character that moves on the screen.

>javascript

>Parametricity
How do you mean?

What should I use then?

TypeScript front end, F# backend.

If you want better performance, use OpenGL and opengl.org/wiki/Primitive#Point_primitives

Those are all the same thing, and all caused by this line of thinking

Participating in competitive programming in a bit as a noob. Wish me luck that I don't completely bomb the whole thing and at least get like 2/8 correct.

What line of thinking? I don't care what causes that problem, when i pick a language i have to deal with that shit.

I'm not going to use ocaml for mobile development when F# was much much much better support for such shit. I can't ignore that fact despite ocaml being technically better as a language.

vim/emacs

Haskell has loads of great libraries on hackage

F# sucks, though.

I'll do it later if I'll need to render more than 2000 things at the same time, the last time I tried OpenGl I gave up.

I know. Other langugaes have many many more.

no

i have some projects that need websites
you are using a website

people seem to be successfully using node for asynchronous/distributed stuff. i know erlang has great support for this too but it doesn't get nearly as much attention, it seems to me

yes

>Other langugaes have many many more.
[citation need-

Oh, you mean all those retarded OOP libraries like .NET that do nothing but wrap and wrap and wrap shit.
You don't mean actual features.

The goal of OOP is to procrastinate actual programming as long as possible.

pls r8 github.com/Dwillnio/4chanThreadViewer/tree/master/pkg4chan/explorer
>inb4 why didnt you use a json library

no. F# is good

the only excuse java has for the java virtual machine always running is portability.
C# isn't very portable, unless you're counting mono, but .NET is always there, abstracting for no reason at all.

All the disadvantages of java with none of the advantages. Welcome to microsoft's backyard.

You'll get much faster development if you use Haskell or Scala or Clojure or Scheme or CL

People who use node only do so because they're incapable of learning a second language

are you that comma split/parser user from yesterday?

nodejs' way of doing concurrency is terrible

Lame

>Oh, you mean all those retarded OOP libraries like .NET that do nothing but wrap and wrap and wrap shit.
how is that not a feature?

>The goal of OOP is to procrastinate actual programming as long as possible.
Exactly. That why it's good for getting shit done.

yeah

nope, I'm afraid it isn't

it only seems like it's good if you've never seen any other functional language

>he's still parsing context free languages like regular languages
kys

Though they are kind of wack in java, doesn't it have those strongly typed enums?

No, it is. I've seen other langugaes and I still know it's good :^).

>how is that not a feature
FileReader(Reader(Stream(Console(

I'd like to get into pen testing. What are the 5 most important languages to learn?

F# is the same as what happens whenever any dysfunctional language decides to take a feature from a functional language, they always take the most rudimentary, limited, first-order approximation of it and it ends up being almost useless.

How do you guys find things to work on? I've done most of the programming challenges and want to make something useful now, but there is just nothing I can think of.

>learned few words that sound buzzy
Okay fag, tell me difference between context free grammar and regular one, also elaborate your main point

Depends - what sort of pens? Biros? Fountain pens?

What's that got to do with a strong library ecosystem?

English, C, intel x86-64 ASM, lambda calculus, coq

>the last time I tried OpenGl I gave up
Why?

Useful? Hmm you know how there is always mess in file system. Make sorting program. So everything is in its place. Videos in proper folder, books in their own etc...

But F# isn't any of those things. That's why it's great.

make a game

That's what you mean by a "strong library ecosystem"

Take .NET's libraries and divide that by 5 because of OOP nonsense
Then divide it by 20 because of the verbosity of coding in the language

Now you have the equivalent haskell

Php, java, hindu, windows batch scripting, light grasp on english

it has no support for higher-kinded types

so it can only do extraordinarily basic abstractions

so it's shit

Yeah, it would be nice to have those I agree.

But it's still great.

I can use langugaes with those features, but then i lose the wide quality platform support and strong library ecosystem.

any jvm language would fit that, on the other hand you get jvm... so who knows

okay, but why would i divide by 5 or by 20? What has verbosity got to do with the usefulness of the libraries?

Find something that you like to do often. Whether it be a certain game, an activity, or just really anything. Make something small that relates to your pick, and slowly expand on it.

What also works is just following up on random ideas in your head and seeing where they end up. I had a random thought after uni about a program that would randomly throw you around the system, and I ended up making it after I got home.

>wide quality platform support
>strong library ecosystem
You're literally just repeating the sell talk now
Got any real reasons?

>But it's still great.
It's not, though, and you've just admitted it. It's the least imaginative 'functional' language out there. It would be better if it didn't exist, because right now it serves to pull people toward it instead of to better languages, and people come to think that functional programming is as shit as F# makes it.

Not him, but an instance of a cfg that isn't regular is a language like c

Too many things to learn.
With SDL2 I can pretty much write my own stuff, with OpenGL I have to write what OpenGl wants.

There's no JVM language as good as F#. And JVM is pretty shit for mobile development, which I'm fond of.

I just told you
Divide by 5 because of the OOP bullshit, like the example I gave
Divide by 20 because of how poor the abstraction is

Scala's on JVM, but with type annotations as verbose as Java

Those are good things for productivity.

>It's not, though, and you've just admitted it.
No, i explained why it's great. The ecosystem is part of that.

>Too many things to learn.
You don't have to use most of the functionality OpenGL provides.
>With SDL2 I can pretty much write my own stuff, with OpenGL I have to write what OpenGl wants.
What do you mean?

Scala, despite its many, many problems, is far better than F#.

maki for you

Huh isnt whole android based on java? I dont know how more mobile you can go

>Those are good things for productivity.
"strong library ecosystem" and "wide platform support" are just abstract base classes with no inheritors

>can only express the most basic abstractions in it
>it's great lol

Not having to repeat yourself in code is also a good thing for productivity, and it's something that no .NET language currently has.

I mean that it's a lot simpler to use.

I don't see how that "OOP Bullshit" is bad. Simple .NET wrappers for other libraries are useful as fuck.

>Scala
Scala is monstrously fucked up. It's worse than Java by a long shot.
youtube.com/watch?v=uiJycy6dFSQ

otherwise I'd probably use it.

Java is pretty shit for iOS development.

Which are useful as fuck.

I agree. But the ecosystem is far more important than having extra DRY code. I guess that's my opinion, but it seems to be true too.

He's a bit of a dunce mate

>I don't see how that "OOP Bullshit" is bad

What's the more advanced ways? Update every 16ms OR if something has actually changed, then update?

Haskell has an absolutely fantastic ecosystem. It might not have as many libraries, but the ones it does have are immensely powerful and couldn't even exist for most other languages. Would you rather have a single silver spoon or a choice of a dozen plastic spoons?

Oh, and although Paul has ranted about Scala's problems several times, he has also said he thinks it's probably the best language around right now.

a context-free grammar is more complex than a regular one.
a context-free grammar may contain recursive structures.
parsing a strict, flat subset of a context-free grammar like a regular grammar is possible, but not recommended and easy to get wrong (e.g. if a structure always has exactly 0

is setting a 256bit random char token in a cookie/database secure enough to give access to a page?

>worse than Java
False. You can use Scala as 'Java without semicolons', so it cannot be worse than Java.

If your complaint is that you cannot always read others' Scala code, then maybe the fault is with you and you should go read a book.

OpenGL is much more powerful.

im not that user, but okay maybe you didnt just remember buzz words.

Whenever i have to use jvm for whatever reason i just use scala at least its succint...

If it's 2D, GameMaker or C++ with OpenGL or SFML (there's a few other proper engines, but GM is friendly for beginners, if a bit retarded, but if you get the hang of it and realize it's shortcomings then C++ with OpenGL or SFML is the way to go, there's a book specifically for SFML around.
Don't touch Unity and I think Unreal is overkill for a beginner platformer.

Run the bot as an external process.
Niche language. Very good for servers and surrounding infrastructure, like CLI tools and peripheral services.
Go.

why not sdl alone? It should do the trick for normal 2D games, also in sdl2 textures are hardware accelerated so it wont be as slow as sdl1

Go is absolute garbage. Don't recommend it for anything ever again. Educate yourself.

>using a non-monospaced font for programming
>java
>all those o(n) and higher methods called back to back while parsing

Thanks

Constructive criticism, friend. Have a (You)!

go was literally designed for people who aren't capable of using other programming languages.

What do you recommend to use for fucking backend? Choice is pretty much java, python, ruby and horse shit php

...

Go gets products and coproducts the wrong way around at the very heart of its API design.

How should I do that better? Are you critisising the methods themselves, i.e. they are inefficient?

welp, time for you to fuck off 2 >>Cred Forums

user () suggested SDL, which I have 0 idea about, I just know that OpenGL can be a pain, and that setting up SFML was incredibly easy, just need to link every library it has when compiling the game. Look at SDL too if you go the C++ route.

Please educate yourself. There are plenty of options for backend. I used to work as a backend web developer in C++.

Still not very descriptive.

Anybody tried pic related desk mounts for monitors or know of any really good ones?

I will consider it, thank you

Are there any good frameworks for cgi with c++? That would be awesome

It is perfectly descriptive. Go's APIs use products where they should use coproducts.

Not programming related, fuck off retard.

Well, it depends on what your definition of good is. There are some FastCGI frameworks, but after having worked with mod_wsgi, I would say that FastCGI is pain.

We used IIS in my old job, there's a FastCGI framework for C++ and IIS called Blackbox at least, but it's 20 years old and not many use it.

Use interfaces and define methods on the passed type.
Unless you can expand on why you think you opinion is right or point me to an article explaining this, your arguments do not look much more than "X does Y wrong, because I said so".

ASP.NET.

/dpt/ hates webdev in general.

I humbly submit that you ought to learn more about programming before replying to me.

Still no explanation on why X is wrong.

Why would you use a product when what you have is a coproduct? It's madness.

The difference between madness and innovation is social acceptance.

Any hardware programmers here?

But this isn't that. This is trying to put a square peg in a round hole. It's insisting that 1 + 1 = 1 x 1.

How long does it take to become good at programming?

I can do basic C and with a small amount of googling can probably achieve most things with it.

But soon as I hit OO, I get so confused!

And you still have not explained how X is wrong.

I have, you just don't realize it.

Probably about 10 years

I thought it was just crossdressing?

There's no reason to not do both. Making cupcakes for your sweet boyfriend while crossdressing and cosplaying as his waifu increases your programming skills by a factor of at least 23%. It's scientifically proven.

I never watch any programming related vids, it's an unfortunate case.

I usually just watch (more listen actually) to speeches given about some topic.

Object Orientated help please.

I'm trying to implement a poker game in C#.

I have a deck class that creates a deck, shuffles and cuts the deck and can also deal out cards.

I'd like to then deal a card to a player that I create. And then be able to print the cards that have been dealt to that player.

So far I've managed to deal the hand to the player by passing the Card object to the player.

However, when I want to print the card that the player has, I try and print by calling the Deck class and passing the cards.

But the compilation fails as the player class can't see the Deck class.

Is that correct?

Make the linux du command with the user being able to use the h and s flags.

:(
is it cheating to use wget?

Probably.
C sockets aren't too bad, but if you want to make it easy, you could use libcurl

sdl2 already uses opengl, tard

Yeah, it would be mostly listening if it was during dinner.

Got any vid recommendations?

new thread when ? :3

>Card class

In case you're interested in mathematics, I'd recommend Project Euler.

That doesn't work, you cant specify the types of lambdas specifically.

Madness? This is Sparta!

how do you pronounce euler?

yew-ler?

>player class can't see the Deck class
Not sure if I understood that right but couldnt you just pass a reference to the deck class in the players constructor

oiler

Player Class:
using System;
namespace Poker
{
public class Player
{
private String name;
private Card[] hand;

public Player(string playerName)
{
name = playerName;
hand = new Card[2];
}

public string getName()
{
return name;
}

public void addCardToHand(Card newCard)
{
if(hand[0] == null)
{
hand[0] = newCard;
}
else
{
hand[1] = newCard;
}
}

public Card[] printHand()
{
return hand;
}

}
}

Snipper of Deck class to print hand:
public void printHand(Card[] card)
{
for (int i = 0; i < 2; i++)
{
Console.Write("Suit is: {0,-10}", Enum.GetName(typeof(theSuit), card[i].get_suit() - 1));
Console.Write("Value is: " + Enum.GetName(typeof(theFace), card[i].get_faceValue() - 1));
Console.WriteLine("");
}
}

And main game class:
using System;

namespace Poker
{
class MainClass
{

public static void printNamedHand(Player name)
{
Console.WriteLine(name.getName() + "'s hand is:");
Deck.printHand(name.printHand());
}

public static void Main (string[] args)
{
Deck Deck = new Deck();
Deck.shuffle();
Deck.printCards();
Deck.cutCards();
Console.WriteLine("Cards now being cut\n\n");
Deck.printCards();
Player player1 = new Player("Just_Steve");
player1.addCardToHand(Deck.dealCard());
player1.addCardToHand(Deck.dealCard());
printNamedHand(player1);

}
}
}

On the Deck.printhand call, I'm getting "Object reference is required to access non-static member" error.

jewler

>yew-ler

Because printHand() is not static.
You can only call methods in the form of Class.Method() if they're static, if they're not static you need to instantiate the class and use that object to call the method.

oiler

the public void printHand(Card[] card) method doesnt access any of Deck's fields/variables right?
So you should make it static in this case
I dont really get how youre calling the method atm anyway the printHand() method doesnt really make sense to me

No, I think I know what I've done.

Deck.printHand() is going to the class, not the object Deck. I've basically done a terrible naming scheme that the class and object have the same name,

That's right isn't it?

Wait you can Objects the same as their class in C#
LMAO
yeah I think thats it try and fix it

Oh in case you overlook it, you need to pass your deck object to printNamedHand(Player name) as an argument and call printHand() with that otherwise it still wont work

Apparently so. I only realised after I noticed the colouring that the keyword was was blue (for a class) instead of white for the object.

By passing in the deck object to the printHand method, it now works right.

Thanks guys. I'm sure I could implement this in a much better way, still learning.

can confirm it does in firefox and chrome on both, but only if you have the page autorefresh

Ah, that would explain it I guess.

It's the first number in the list, dipshit.
