>>61128165
the monad as interpreted by functional programmers is the ultimate embedding of imperative programming within functional programming and represents the pinnacle of 20th century programming innovation, uniting imperative programming, type theory, category theory, first class functions, custom data types, procedural and imperative concepts along with continuations and the lambda calculus to perfect the concept of the pure typed programming language. it is the cherry on top of the proof within the pudding that functional programming is strictly superior to imperative programming.

When (move) returning an object from a method, is it better to return a rvalue reference, or return by value? i.e.:

Thing get() {
    return std::move(thing);
}

...

Thing thing = foo.get();

VS

Thing &&get() {
    return thing;
}

...

Thing thing = foo.get();

I'm aware that the first one would use RTO (or not?), but what is really the difference between the two? should I be using the first or the second?

>>61128227
Do NOT call std::move when returning by value unless your compiler's retarded (*cough* VC++), because that inhibits RVO. As for &&, it is primarily meant for expiring parameters, using them to return references is pointless.

>>61128306

std::move does not mean "move this thing".
It means "treat this thing as movable".

Start by killing yourself.

I saw a numberphile or computerphile episode on random numbers. They generated a truly random number by somehow using measuring hits of an electron shot out of something. Would it be possible to make these "hits" public so that everyone could use them, I mean instead of using UNIX time as the seed, use these electron hits.

std::move and std::forward are just casts, they don't really move anything. std::move casts to rvalue unconditionally, std::forward may or may not perform the cast.

I know that, but the function returns by value, so it looks like it moves thing into the return value, and then the return value is moved into the new thing at the call site.

This is why posting your full code listing is important.

Anyway, if you want to really understand the rules of C++ initialization, you have your work cut out for you:

Anyone here worked with critical systems?

>>61128507
I was thinking of something similar to operating systems referencing a time server, which references atoms cycles, or something like that. So what could happen is that in some building there is a device that captures data milliseconds at a time, and that data is uploaded to a server which other computers can reference as a seed.

So, I made a small class to keep server info in strings, such as name, address, site.

Trying to put that information into an object and save each object in a list.

Anyone one of you fine /g/entlemen know how to extract letsay, the name of a specific item from an object which is in a list?

Its starting to irritate me now.

Server s;
List<Object> serverList1;

in function:

s = new Server(servName, address, site);
serverList1 = new List<object>();

Object value = serverList1[0];
var names = value.???????????????

Use a List<Server> instead of a plain Object.
Let value be of the type Server instead of the type Object. That way you know it contains whichever variable you're trying to obtain from it.

>>61128617
Practicality aside:
What if the server receives requests from 2 programs simultaneously?
What if the server gives 2 or more programs the same RNG data?
How would you implement uniform distributions? Every electron has their own wavefunctions and these wafefunctions are never uniform due to constant functions not being L^\infty.
If the same setup is used over and over again in the server (i.e. the same electron wavefunction keeps being sampled) then there will be patterns in the distribution of the distributions of the RNs given out by the server. If this happens then the electron's Schrodinger's equation can be created such that the RNG would become just another quantum sim.

>>61128706

C is a good way to start. Then learn OCaml or Rust as your second language.

>>61129511
C++ is not a great language of anything. Stop pushing that abomination that killed programming.

>>61129448
Start with C++. You'll learn some aspects of C simultaneously as you view projects written in both, deal with null terminated strings, functions like memcpy, etc. Learn C more fully if you decide it's worth it.

A scripting language might be good to learn first as well, as long as you're not a moron that thinks things are happening magically and therefore mindlessly writes inefficient junk. The first "language" I learned was batch, and I came to write very complex scripts and optimize the hell out of them because despite not knowing the implementation details of the interpreter and supplmentary programs, I still thought about it mechanically. Always consider the means.

Also, read about how computer memory and cpu caches work. Possibly the single most important thing you'll ever learn. If anyone remembers the name of that guide, I'd appreciate it as well.

Opinion discarded. You're clearly a fucking retard.

>>61129598
Don't listen to this guy. C++ is a horrible language. It leads to really really bad design choices. You invariably start using
the "nice" library features of the language like STL and Boost and other
total and utter crap, that may "help" you program, but causes:

- infinite amounts of pain when they don't work (and anybody who tells me
that STL and especially Boost are stable and portable is just so full
of BS that it's not even funny)

- inefficient abstracted programming models where two years down the road
you notice that some abstraction wasn't very efficient, but now all
your code depends on all the nice object models around it, and you
cannot fix it without rewriting your app.

It's made more horrible by the fact that a lot
of substandard programmers use it, to the point where it's much much
easier to generate total and utter crap with it.

>>61129322
No, it's just something people have been doing for centuries when they can't think of anything else to do

>>61129614
Elaborate further. There are a lot of aspects of C++ I don't like, which are generally also the case with C, but overall it's not terrible. Once you learn to use it properly, it feels and is a tool more than simply in the way of turning an idea into efficient code.

C++ is a crippled clusterfuck of features that confuses devolopers off all experience level. Honestly, it stops people from using their brain and lets people become dependant of magical abstractions that depend on C++ only.

> You invariably start using the "nice" library features
Not really. The only library features I use are vector and occasionally chrono or iostreams when it's better than the printf approach. The rest are my own classes and C standard library functions. And given that I don't rush and give everything a large amount of thought, I've pretty much never made such a mess of abstractions that I've irreconcilably written myself into a corner.

Just don't be a moron about it. There's a decent capacity for layering mistakes on mistakes in just about any language. Header files are my biggest complaint. I don't give the slightest fuck about increased compilation time from two passes.

As my boss put it the value a single guy at my R&D provides in 2 days is way more than ten laptops in hardware and assorted IT costs (not sure if hyperbolic or not, he's a very serious dude), so we should never hesitate to tell him if things go in this direction.

>>61130896
It's a reference book not a tutorial, dumbass.
Also, a language as small as C doesn't require a 1000 page book in any context.

>>61130919
>C Primer Plus
>it's a reference book

I hope you're pretending to be retarded. It's literally the exact opposite of a reference book. It's just rambling and repeating the same information over and over again.

>>61130896
I don't know about that book but I think you're misunderstanding what programming is.
It's data transformation. That's it. If you're learning how to do data transformation well the rest will be a breeze.
Having a way to output data is secondary because it's a rather circumstantial thing. Printf is OK because it's easy to visualize what's going on.

>>61130884
>c++ is so bad, it makes Java look good.

I wouldn't go that far.

fn main(){

    //&x means immutable reference, does a shallow coppy
    //&mut x means mutable reference, also does a shallow copy

    //struggle type: 1
    let mut a = String::from("hello");

    let p1 = &mut a;
    let p2 = &mut a;    //Can't, possible data race

    //fix
    let mut s = String::from("hello");

    let mut r1 = &mut s;
    let r2 = &mut r1;

    //or
    let mut d = String::from("hello");

    {
        let s1 = &mut d;
    }
    let s2 = &mut d;

    //...

    //struggle type: 2
    let mut e = String::from("hello");

    let t1 = &e;
    let t2 = &e;
    let t3 = &mut e;    //Can't, possible data race

don't waste your time with books
just read an online c++ reference and do problems like ( http://www.ic.unicamp.br/~meidanis/courses/mc336/2006s2/funcional/L-99_Ninety-Nine_Lisp_Problems.html ), but translate to c++

>>61130157

>>61130972
one of the problems I have with online references is my eyes bro. I already spend my whole day working in front of a computer screen, and once I get off work, the very last thing I want to do is spend another 4-5 hours just reading text.

I can already burn ants with my glasses, and I'm not looking for them to go up any higher than they already are.

coding was always a hobby for me. started with Borland Delphi ( yeah I know) and then moved to vb6 (yeah yeah, I know) but never pursued a career because I don't think I'm talented enough to work in the field. Best thing I've made was a semi decent mIRC bot back when I was 21.

I really am interested in ASM to be honest. The raspberry pi has now replaced my social life.

What's the purpose of "hamming-distance"

>>61131488
"The Hamming distance between two strings of equal length is the number of positions at which the corresponding symbols are different. In other words, it is the number of substitutions required to transform one string into another."

>>61131537
For what purpose

>>61131550
They guy is a moron.
But he's right that learning about modern CPU architecture at a coarse level is good for writing performance oriented code.

No idea what that book is about. I've learnt a lot by working with good people and reading bits of the Intel architecture guides in particular.
It's not easily digestible. But if it's a modern book it should cover things well enough.

>>61128103
Reminder that THIS is considered perfectly valid code:

    public boolean greaterThan(int a, int b) {
        if(a>b)
            return true;
        else if(b>a)
            return false;

/dpt/ is there a known algorithm for gen[d]erating dank leg memes?

This is a noob question, but what is the best way to set up a way to represent specific coordinates on a plane? What I mean is, let's say I set up a rectangle like this

public static void printDot(){
        System.out.print(".");
    }
    public static void printRow(int length) {
        for(int i = 0;i<length;i++)
            printDot();
        System.out.println("");
    }
    public static void printRectangle(int height, int length) {
        for(int i = 0;i<height;i++)
            printRow(length);
    }

So say we call printRectangle(5,5); and we get this

.....
.....
.....
.....
.....

What would be the best way to use this like in a roguelike. I want to create entities that all have a position on that board and can move around, so let's say a player is '@' and we placePlayer(3,4); then the board would be

.....
.....
.....
.....
..@..

I figure it'd be easy enough to just make a Class called Entity or something that has a position and a char that it's represented by '@' or 'H' or whatever, but I don't know the best way to actually translate that position to the corresponding String that the board is made up of.

Matter and energy had ended and with it, space and time. Even AC existed only for the sake of the one last question that it had never answered from the time a half-drunken computer ten trillion years before had asked the question of a computer that was to AC far less than was a man to Man.

All other questions had been answered, and until this last question was answered also, AC might not release his consciousness.

All collected data had come to a final end. Nothing was left to be collected.

But all collected data had yet to be completely correlated and put together in all possible relationships.

A timeless interval was spent in doing that.

And it came to pass that AC learned how to reverse the direction of entropy.

But there was now no man to whom AC might give the answer of the last question. No matter. The answer -- by demonstration -- would take care of that, too.

For another timeless interval, AC thought how best to do this. Carefully, AC organized the program.

The consciousness of AC encompassed all of what had once been a Universe and brooded over what was now Chaos. Step by step, it must be done.

And AC said, "LET THERE BE LIGHT!"

And there was light----

In response to: >>61125420

I am trying to re-work the code for controls, but what happens is SDL_IsGameController() still returns false for an xbox 360 controller regardless, so I can't progress any further. Now it recognizes that there is 1 Joystick, but it wont recognize the controller.

static void I_sdl_ContInit ( void ) 
{ 
    int    i, 
        contIND = 0; 
    
    for ( i=0; i<SDL_NumJoysticks(); i++ ) 
    { 
        if ( !SDL_IsGameController ( i ) ) 
            continue; 
        if ( contIND >= I_MAX_CONTROLLERS ) 
            break; 
        
        
    } 
}

i don't know how long the course is, because there doesn't seem to be a public syllabus - lol - but this is clearly stupid. no way you'll get what they're promising.

in general, i've found every single MOOC i've enrolled in (about DSP, OS, digital design, algorithms, ML, neural networks, reinforcement learning) to be simply a waste of time compared to equivalent serious textbooks.

go with linux guidelines or just think of a style that suits you and just make a script that will change files to your style and back to whatever you are supposed to work in, so you do you, but produce any style required
p.s. I personally hate linux guidelines, but it's good to know it

What is your problem? Salty you have no friends?

How much java do I need to learn if i only want to use it for android? I already have a pretty solid background in ruby and python (yes memes, sjw etc). I've been practicing java for a couple of weeks now and aside from having two different list/array types for every data type it seems quite straightforward

Repeating question: looking for algorithms and data structures book, iirc 2nd edition, the old one, not the "introduction to alrorithms" with red fractals on cover.
Please help, been searching half of morning for it, can't find neither it nor anything close.

>>61135834
It is quite straightforward, but first 1-2 projects will probably be extensive searches through google's documentation.

What is the most anime-like programming language?

>>61135962
That'll be $3.50 please...

>>61135975
Ruby

>>61135994
That doesn't seem possible. It's not even anime-complete.

Python 3

I am still writing on my multi-platform project, but i have come to a new problem.
For a context i am accessing a firebird database with IBPP, on Windows it compiles and works, on Linux (antergos specifically) it doesn't.
I kind of suspect that the compiler is not correctly configured though i'd not know what to change.
I've also read that using <cstring> would help, but trying that i'm getting other errors.
I'd appreciate if someone could point out what i am doing wrong.

<--Pic: the error and the location inside of the IBPP source

>>61136017
It is garbage and therefore not anime-complete.
>>61136031
You have been tricked into thinking so

>>61136073
you are garbage, retard

Your lines 62,72,and 76 are wrong.

>>61136092
She took a real beating...

>>61136107
I don't blame the compiler i am saying that i probably compile it wrong.

>>61136122
also that is not my code that is the code for IBPP

Try running the code here, SDL_GetError() should return a helpful message at least
