TOP KEK

Learning Java, and they tell me:

>Now, you probably start to wonder why does the value of the parameter get copied and the original variable stay intact when the parameter is of int type, but the original list is given to the method when the parameter is of ArrayList type? In Java only the values of primitive data types (which are int, double, char, boolean and a couple of others that we have not yet discussed) get copied to the method.

Why did they do this?

>>56763620

>>56763461
There is no C build system in sublime. I tried building one by getting code from stack overflow but it's all shit

>>56763641
Larger types, like objects are passed by reference (hence they are reference types). It's an optimization.
it works the same in e.g. C# or Python.

>muh macro
egoinflating oldshits like vi are useless if your programming style is good

why do people put `void` where the args are supposed to go in functions that dont take args when it works without?

is it something wizardy for the compiler like const?

>>56763903
Because they're gay

>>56763903
Old versions of C required this, because empty argument list meant the function was taking variable argument list. I.e.

foo()

Meant the same as

foo(...)

>>56763903
In C:
>void foo() means "a function foo taking an unspecified number of arguments of unspecified type"
>void foo(void) means "a function foo taking no arguments"

In C++:
>void foo() means "a function foo taking no arguments"
>void foo(void) means "a function foo taking no arguments"

>>56763903
only does matter with prototypes.

>>56763903
It's was required back when there were still compilers that parsed K&R C code. It signified that the function doesn't take any arguments instead of filling in the first n variables declared in the function like in K&R C. It's unnecessary now, and it's mostly there as an anachronistic 'style'.

The reference is passed by value, so you cannot assign a variable for a reference type to a new value, as in

{
    int temp = x;
    x = y;
    y = temp;
}

Been reading up on html and JS on w3schools for the past few day. Finally get up to the window BOM chapter. "Oh, so this is where the fun stuff happens". Not a fucking mention of window.AudioContext.

Fuck everything. I hate programing. It's just language constructions this and language abstractions that. No one ever fucking teaches you how to actually work with your hardware, so you don't learn do do anything useful. Every programing course is just a load of wanking.

>>56763328
This has been my screen saver for over 6 years.

>>56764238
First of all use MDN instead of W3Schools.
Second why the fuck do you expect low level hardware programming with JavaScript?

>>56764238
I think you meant DOM. Also don't read w3schools. See: http://www.w3fools.com/

You want to render them in bulk and avoid allocating and deallocating them.

Why is opengl such a nightmare.

>>56764500
They will be rendered in the same spritebatch, all at once.
Can you explain allocating and reallocating? It doesn't have to be in depth.

>>56764575
>I just wanna make video games
If you're not interested in the internal workings of a game engine, use Unity or Unreal or fucking GameMaker.

>>56764572
Does anyone else pronounce aliasing as analysing when reading it in your head?

>>56764624
Honestly the real problem is that I am, it's just that opengl is so unpleasant to write. I was working on a wrapper for love2d in moonscript, but got fed up w/ that project.

>>56764347
Rendering ~50 sprites individually wont have any noticeable performance impact. If that's the only thing you wanna do go for it anon.
But if you're interested here are some way you can create a better sprite renderer.

> 1
You count how many sprites you have and calculate the size of your vertex buffer. do the vertex transformations on the CPU and send it allover to the GPU and render it all at once.

> 2
Use instanced rendering.

> 3
Just send single points to the GPU and use the geometry shader to create the quads.

Keep in mind that if you use a lot of textures or if Z order matters you want to record the draw commands in a buffer first and then sort it before drawing.

>>56764575
you use opengl to program a renderer then you use that renderer to program a game. if you want to program a game, not a renderer, then bypass opengl by using a already existing renderer (ogre3d, panda3d, udk, ...).

The parameter x initially is a reference to the i in main(), but you assign to it a reference to a different object. This doesn't change what i refers to back in main.

Try this:

public class A {
    public int a;

    public A(int a) {
        this.a = a;
    }

    static void a(A a) {
        a.a = 4;
    }

    public static void main(String[] args) {
        A a = new A(5);
        a(a);

        if (a.a == 5) {
            System.out.println("Pass by value");
        } else if (a.a == 4) {
            System.out.println("Pass by reference");

I'm a little messed, please help.

I tried learning C and then python, but I can't understand C, so I'll do the opposite, python first. but
what python? I remember being problems between python 2.x and python 3.
any advice here? I don't mind reading but there is an awful lot of books out there and I don't want to spend time with an useless manual.

>>56765979
Hard to tell. PHP is shit because it was designed as an HTML template language, or more accurately not designed at all. JS has been shit until recently because it was designed in 10 days. If both are given several years of development from zero, we will certainly get much better languages out of both.

I need a method that takes a user-set weight, compares it to a set max weight and substracts a percentage from a set max speed depending on the percentage of usage of the max weight.
For example:
>100 km/h
>1 ton max weight
>0.5 ton used
>speed is decreased by 4% for every 10% of the max weight used
>20% is cut from the max speed in this case
>return new edited speed 80 km/h

Writing old thread cleanup for an imageboard. What would be a decent algorithm for calculating the dynamic "page" number of a board? Trying to think of something that will work for both big slow threads and lots of small ones.

Learning programming with C Programming a modern approach 2nd edition, and I was wondering how long does it typically take for somebody to finish all the exercises and programming projects? There are a ton of them and I feel like some of them are just kind of tedious. I just finished the chapter 7 exercises and programming projects and it took a fairly long time, not because I had to think of how to make it work, because of all the switches and if's (i literally just laughed and skipped the question that asked me to use goto)

>i literally just laughed and skipped the question that asked me to use goto
The goto statement is a valid part of the language. You better learn how to use them correctly instead of being ignorant.

Albeit deprecated by some people, the equivalent of the goto statement is
used frequently by compilers in form of the unconditional jump instruction.

The goto statement comes in handy when a function exits from multiple
locations and some common work such as cleanup has to be done.  If there is no
cleanup needed then just return directly.

Express.js question, /wdg/ is dead at the moment.

Extremely simple, but I can't for the life of me see what is going wrong here.

I've got two routes, GET and POST for '/newnote'.

// GET newnote
router.get('/newnote', function(req, res) {
    return standupCtrl.getNote(req, res);
});

// POST newnote
router.post('/newnote', function(req, res) {
    return standupCtrl.create(req, res);
});

They deal with requests via a method attached to standupCtrl, which is required into the routes file. The get request for '/newnote' works fine. It's hunky dory. It serves a jade template via a standupCtrl method. The template looks like this:

extends layout

block content
  form(method="POST", action="/newnote")
    btn.btn.btn-info(type="submit") Submit

It couldn't be any more simple. This should hit the POST route. Something should happen, but it just isn't. The .create method within that POST method only contains the following code:

res.redirect(301, '/');

Any ideas? What is it that I'm missing?

>>56768279
i hear you, though let's be honest, /agdg/ is pretty shitty overall too. i do like that people actually discuss their projects and post "progress", but it's also largely a dramatic circlejerk. i think the difference with /dpt/ is that people try really hard to sound knowledgeable and love doling out loud criticism despite frequently being painfully wrong, which probably discourages some people from sharing their work. most people here are way better at arguing pointless semantics and reading language specifications than they are at actually programming

I agree, /agdg/ is not working as well as it could. But at least they have recaps, jams and other community events.

> I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux.

Fuck it's seems obvious after you said that. I was thinking of shifting the values of the array whenever I can't across the "target" number until the start was empty or the counter was 1 at the end of one cycle.

My uni let me take this 2nd year data structures and algos course directly without the 1st year CS courses so I have no experience implementing basic data structures or even sorting algos. Seemed like a good idea to graduate faster but I might've fucked up.

>>56769417
I meant "whenever I came across" and "until the array was empty"

I'm not even in college, cs degrees are a literal scam.

>>56769282
Not efficient, sorting would take O(n log n) time but checking duplicates only requires O(n) time and space, by recording instances as you go through the array.
