Tried and true.

My program crashes, but only sometimes. It never crashes when I'm in debug mode. That's usually a sign of a mishandled pointer, right? I can't find any non-deleted pointers anywhere.

You're just propagating the pointless entropy of the universe.

>>55775047
I just found a single unassigned boolean that I don't even remember creating in a file that hardly ever gets used. Removing it seems to have fixed the issue.
Unless of course this is just a fluke sequence of non-crashes that will end any time now. I really find it hard to believe that removing a single variable could fix it, especially since this problem just recently started, after months of no issues.

You put the system name after the "../"...

And also, I did a bit more digging and think the dual 32 bit and 64 bit binary setting might be messing with your build also. You could try to only go 64 bit with "-DCMAKE_OSX_ARTITECTURES='x86_64'" or committing the option entire since I'm sure CMake can configure automaically.

macOS hasn't used 32-bit since Lion so I'm sure unless you care about legacy, it would be fine to drop i386.

>>55775452
then you probably don't need them yet. unless you're building something right now that you're having trouble with/you think you might need typeclasses for? if so post details

You're confusing "low level" with "badly designed."

If someone wanted to learn about dynamic typing and closures, would you start by teaching them how to write JSFuck in JavaScript? No? Then why would you teach them C? C is JavaScript-tier crap made by noobs.

All of the low level programming in C is "undefined behavior" anyway.

dunno why I'm still here, I guess it's because of the need for """"socialization"""".....

Where is the line drawn on copying code in a professional environment?

I don't mean straight up copy-pasting a full program. I'm talking about something as simple as copying a sorting or pathfinding or fill algorithm straight off a tutorial website.

I'm obviously more than capable of personally writing out a bubble sort, to use a very basic example, but my job isn't to reinvent the bubble sort. It feels like a waste to spend any amount of time re-writing (and potentially accidentally messing up) something so absolutely basic.

I just made my vim experience 1000 times better by finally setting up proper split management mappings.

" Split navigation
nnoremap <C-Down> <C-W><C-J>
nnoremap <C-Up> <C-W><C-K>
nnoremap <C-Right> <C-W><C-L>
nnoremap <C-Left> <C-W><C-H>

" Resizing
nnoremap <C-S-Up> <C-W>+
nnoremap <C-S-Down> <C-W>-
nnoremap <C-S-Left> <C-W><
nnoremap <C-S-Right> <C-W>>

" Easier splitting
nnoremap <M-Up> :aboveleft split<CR>
nnoremap <M-Down> :belowright split<CR>
nnoremap <M-Left> :leftabove vsplit<CR>
nnoremap <M-Right> :rightbelow vsplit<CR>

" Buffer navigation
nnoremap <C-PageUp> :bnext<CR>
nnoremap <C-PageDown> :bprev<CR>

>>55775743
Copy-pasting anything from the internet is a terrible idea.

If you're using existing code as a guide (perhaps porting to a new language) and someone can look at what you write as say "yeah, this almost definitely came from this source" seeing them side-by-side, you've copied too much.

If the algorithm is so simple that all correct implementations are practically identical, you probably shouldn't need to copy.

Is /dpt/ the last bastion of /g/ against full autism?

Seriously, this whole board is the definition of hypocrisy.

The gpu threads are the best example. They hate games, they claim they don't play them(they do) but they always have the latest GPUs and always talk about performance.


Now why do they need them? Cause they play games heavily? Or maybe they actually do something resource heavy? Fuck no, these asses play gaes 24/7 and they deny it.

What does it change that they lie about it? They are still a pathetic mess if theu are over 30..

Who cares if he isn't gay or not. The bigger problem is that he's in no way programming related in any sense at all. Editing media to make him seem programming related is retarded and in no way makes the character any more technology related than he will ever be. He's essentially a "forced meme" at this point.

I was fine with Yuki because her original premise at least was somewhat programming related. But it's tiring that a character this old which isn't even programming related keeps on getting posted. It's tolerable but it is honestly tiring and stupid. At least post stuff from Lain, Battle Programmer Shirase or even New Game!. It's honestly better and infinitely more on topic than whatever the Himegoto spammer will ever post.

>>55775711

If you're going to use CMake, at least learn what the basic syntax is. "\" is used so you can write mutiple options on mutiple lines and not run into errors.

You need the following:

cmake -G 'Unix Makefiles' \
      -DCMAKE_OSX_ARCHITECTURES='i386;x86_64' \
      -DCMAKE_SYSTEM_NAME='Darwin' \
      -DCMAKE_CXX_COMPILER='/usr/bin/clang++' \
      -DCMAKE_C_COMPILER='/usr/bin/clang' \
      -DSFML_BUILD_FRAMEWORKS='ON' \
      -DSFML_INSTALL_XCODE4_TEMPLATES='ON' \
      -DCMAKE_CXX_FLAGS='-stdlib=libc++' \
      -DCMAKE_C_FLAGS='-stdlib=libc++' ../ 

Makes sense? Also, try the suggestion I told you earlier about ommitting i386 from the OSX architectures line.

How is this different than a tiling wm?

>>55775804
Instead of managing X windows, it manages vim windows. Vim windows are sorta like X windows, except instead of containing a pixel grid, they contain a character grid.

>>55775821
Right. I'm asking what's the advantage? If I have i3 already should I still be using vim splits?

>>55775829
It'll work over SSH, it is less resource intensive, it allows the windows to share buffers, etc. for easy manipulation in vim (though you could probably find a plugin to make everything work between separate vim processes), and it works in cases where you can't use a tiling WM (on a locked down school or work machine, for instance).

Okay... Thank you for all the help, but it doesn't seem like CMake wants to work today... I copied what you told me I needed (and removed the i386), but I get the error in pic related... It probably has to do with my version of OS X, but then again, I'm new to the C/C++ scene

all right can I actually get some advice on this? control flow seems a bit weird, with some preprocessing done in "huffman" and passing in the "" to parseTree manually - in java or python that would be a default argument. Should I make a helper function here?

data Tree a = Leaf a | Branch (Tree a) (Tree a)

huffman :: [(a, Int)] -> [(a, String)]
huffman xs = let t = consume $ map (λ(x, n) -> (Leaf x, n)) xs
             in parseTree t ""

consume :: [(Tree a, Int)] -> Tree a 
consume [(t, n)] = t 
consume nodes = let ((t, m):(s, n):ys) = sortBy (comparing snd) nodes
                in consume ((Branch t s, m + n):ys)
 
parseTree :: Tree a -> String -> [(a, String)]
parseTree (Leaf x) prefix = [(x, prefix)]
parseTree (Branch t s) prefix = (parseTree t ('0':prefix)) ++ (parseTree s ('1':prefix))

>>55775942
personally, I don't learn a new language without a specific project in mind that is especially appropriate for that language

ex, state machine in haskell

>>55775891
yeah, its never a good idea to have a dum argument
just make a general case in a helper private function, and make ur function a genral case

>>55775913

That's not terribly old but you're not up to date. What did you install CMake from? You should have 3.6.1 or at least a 3.5 variant. I think 3.4.2 is before El Capitan.

>>55775961
*make ur function a specific case

>>55775891
yeah, make parseTree private unless its used elsewhere
and make t also private
so something like

huffman xf - parseTree t ""
  where parseTree = ...
             t = ...

I meant if you installed it from like Maccports, Homebrew, or compiled from source.

The GUI and CLI should update in tandem. You did something wrong somehow. Figure out how to correct your install and try again.

I'm currently building a distributed filesystem/object storage system.

Nodes are just linux boxes running openssh, not node setup other than creating a useraccount and using a script to propagate encryption keys.

metadata is just in a sqlite3 database. everything is encrypted end to end and at rest and data chunks are replicated for redundancy and checked on occasionally to prevent bit rot form destroying your precious files.

Very easy to setup, use and maintain as long as you have some minor linux knowledge. I'm going to be turning it into an android at at some point.

I made it for myself because i hate the over engineered aspect of distributed file systems out right now.

Would this be something that people on /g/ would be interested in? I will eventually put it on github and GPL it.

I've got standardized json responses with "success" and "message", and a result which varies in type.

In your GetType methods, does it throw the exception at the obj line or the type1/2 line?

Set a breakpoint at the type1 line an examine the value of obj.

In your Parse method, try deserializing to a List of your RootObject

RootObject obj = JsonConvert.DeserializeObject<List<RootObject>>(text, settings);

Also, I'm pretty sure you should not have Type1 and Type2, but rather a single type that contains a, b, c, and d. You can break this up after the deserialization.

I'm in a lucky spot where I'm free to improve processes as a see fit most of the time, so while I do it for work, I'm allowed to be creative and create whatever kind of project that would help us in some way.

I'm working on a drag-and-drop ETL abstraction for literally dragging data from our production DBs to the data warehouse.

The idea is to put it in Unity afterwards and have it in a virtual reality where you can LITERALLY drag and transform the data in a 3D world with the motion controls.

He's going to run into the same trap where he has no idea what game to make. It happened to me. Surely you don't want to make another clone?

That and the fact you need a lot of time, motivation and art/audio assets makes vidyadev a really shit proposition.

>>55779565
do you really expect your managers to put on a VR headset and flail their hands in the air to manipulate important data?

>>55779619
Same.
Unity is a great engine and I had the knowledge to build the things I wanted, but I just couldn't think of something truly innovative or interesting(for me). Sure you don't need to make an innovative game for it to be fun or interesting, but i just didn't want to make another rehash or clone. I have the time, motivation and art, just no good solid game ideas that 1 person could finish within 3-4 years.

>>55779598

> Surely you don't want to make another clone?

Why not? They're fun programming exercises. Also, clones sell. Clones + 1 new feature sell even better.

If you want originality there are plenty of idea/ art babbies out there looking to collaborate. There are far many more artists than programmers interested in making games; your skills are a valuable commodity.

>>55779627
Absolutely not.

I'm doing it for fun. The VR part would obviously be on the side or when I have downtime.

It would later allow me to 'gameify' some sort of public API, and give me some gamedev experience.

>>55779671
>There are far many more artists than programmers interested in making games; your skills are a valuable commodity.

Couldn't be further from the truth on that one.

>>55779541
Exact opposite here. I have too many ideas on a project's TODO list and too little time and none to help out. That said, although the code base is quite well documented, it's still moderately big for a one man project and early in development too. That makes jumping in much harder.

>>55779989
because C99 has things lile inline, boolean, floating point arithmetic library

>>55780019
basically i run a image optimizer in my images folder, and the program creates a copy of those images.

now i want to remove the old ones

>>55779989
Why on earth would you restrict yourself to C89? GCC, the compiler you're probably going to use on a GNU/Linux system, has had C99 for ages, and even has C11 support, and even defaults to C11 now.
C99/C11 is a lot nicer to program in, and fixes all sorts of weirdness in the original standard, while still keeping to the spirit of C.

>>55779988
You don't understand
I really don't want the entire output to print out. I want one to print and it disappears for it predecessor and so on. Do you get me? I used range just as an example

Isn't the answer obvious? ANSI C sucks.

>>55780079
It doesn't seem to work

>>55780075

my_fn(arg)
{
    /* do whatever */
}

is valid C89 (implicit int).

Calling a function without a prototype is valid C89.

puts("whatever");
int n;

is invalid C89.

-10 % 2

is implementation defined behaviour in C89 (defined in C99).

But really, C99 adds a lot of things which makes C nicer to write. I use stuff like designated initialisers all of the time, as well as things like variadic macros.

Help me anons! In the following code, I get a segmentation fault if x is larger than y, but not vice versa. What am I not seeing here? (getint() gets the next char from a 2D array of 1's and 0's of dimensions x, y from stdin and converts to an int)

Also bp and np are of dimensions x, y as well

for (int i = 0; i < y; i++){
    for(int k = 0; k < x; k++){                          *(*(bp+k)+i) = *(*(np+k)+i) = getint();      }                                            }

>>55780385
>post-increment

>>55780431
But the index starts at 0...

>>55780493
Your point?

>>55780431
>>55780493
It makes no difference in the 3rd part of a for loop statement.

>>55780385
I can only assume that getint() doesn't work properly.
>*(*(bp+k)+i) = *(*(np+k)+i) = getint();

bp[k][i] = np[k][i] = getint();

>>55780155
RTFM https://docs.python.org/3/library/functions.html#print

>>55780431

>>55780515
Here's getint()

int getint()
{
    char c = getchar();
    while (!(c-'0' >= 0 && c-'0' <=9)){
        c = getchar();
    }
    return c-'0';
}

>>55780506
Huh I thought pre increment in a for loop would increment before the loop ran, guess I know better now

>>55780694
Ok, there is nothing wrong there.
How is 'bp' and 'np' defined?

>>55780538
Well how do you do it in python 2.7?

>>55780724

int **bp, **np
if ((bp = (int **)malloc(y * sizeof(int *))) == NULL || (np = (int **)malloc(y * sizeof(int *))) == NULL){
        printf("Error: malloc returned NULL\n");
        exit(1);
    }

    for (int i=0;i<y;i++){
        if ((*(bp+i) = (int *)malloc(x * sizeof(int))) == NULL || (*(np+i) = (int *)malloc(x * sizeof(int))) == NULL){
        printf("Error: malloc returned NULL\n");
        exit(1);
        }
    }

Sorry if this doesn't format correctly, I'm copying it from vim in termux on my phone

Anyway right after this code, the other code runs and I get the seg fault if x is larger than y

Is this portable (within Linux, and C++14)?
And in what situations would this break?

drv.hpp:

class driver
{
    public:
    virtual void print() = 0;
};

lib.cxx:

#include <iostream>
#include "drv.hpp"

class foo : public driver
{
    void print()
    {
        std::cout << "This is foo\n";
    }
};

foo drv;

main.cxx:

#include <iostream>
#include <dlfcn.h>
#include "drv.hpp"

driver *drv;

int main()
{
    void *h = dlopen("./lib.so", RTLD_LAZY);

    if (!h)
    {
        std::cerr << dlerror() << '\n';
        exit(1);
    }

    drv = (driver*) dlsym(h, "drv");

    auto err = dlerror();
    if (err)
    {
        std::cerr << err << '\n';
        exit(1);
    }

    drv->print();
    return 0;
}

makefile

all:
    g++ main.cxx -ldl
    g++ lib.cxx -shared -fPIC -o lib.so

Works on my machine, prints "this is foo" to stdout as expected.

I'm writing a virtual machine and I want to be able to dynamically load arbitrary IO devices from shared libraries that support the interface, and I want to do it in C++.
I know how to do it, I know it's portable for C libraries, but I don't know of it's portable for C++ libraries.

>>55780808
You've gotten k and y mixed up in your for loop.
Swap them.

Anons i need your help,
I am facing a problem in c
I want to raise (a+b)/2 to the power of a variable time which can be as big as 10^18 (thats quintillion ), i am using long long int for time and ints for a,b ,
i tried using the function pow and powl but they return inf which stands for infinity, that is because pow converts the result to double which is too small , and the same goes for powl which return long double,
Are there any other functions or ways to make this happen with really numbers?

Or store your values in arrays and write your own mathematical functions.

How the fuck change value of string with PHP function? I need to import XML file to my website but some values are in Number ID form, not in word

}

return $x;
}

>>55780854
But k is just a counter and y isn't. Do you mean change i<y to i<x? I'm stepping through the y index of the array and allocating an array of x ints for each pointer.

>>55781041
Oh right. I meant to say k and i.

>>55781048
It worked! Thanks anon

So how bad of a programmer am I if I use vectors instead of dynamically managing arrays. I really dont want to deal with memory leaks in a program thats likely to crash as soon as it misreads one thing.

>>55775117
C, assembly is not required anymore.

If I have a pointer called myObject as a member variable, and I write "myObject = new Object" multiple times without writing "delete myObject", will that cause a memory leak?

>>55781217
Yes. You will have multiple memory leaks.
When dealing with new. Always think about how you are going to delete the new variable. Just call delete before calling new again.

What is the best way to implement order of operations in a program that accepts user input for expressions? Right now I'm doing a series of conditionals to determine the order to execute a function which basically takes two operands and an operator and returns a value. So for example if it wanted to calculate 2 + 4 ÷ 10 it checks the second operator to see if it has higher priority than the first and does

f(2, '+', f(4, '/', 10))

rather than defaulting to

f(f(2, '+', 4), '/', 10)

I'm just wondering if there's a better way than doing a conditional statement to determine the order.

>>55780726
Read the docs you fucking lazy cunt.

>>55781258
Or use a smart pointer.

>>55781121
Really? Unless you have a very specific reason not to use std::vector (that's what we're talking about, right?) then it's the right thing to do.

>>55781121
But STL containers are the way to go, senpai.

should i learn scheme/lisp after i become practical with java? im currently going over c right now.

If I take the modulus 50 of any integer, it's not possible to return a value over 49, right?

>>55781993
Yup.

>>55781978
Yes, do. Really does make you think of programs in more descriptive terms. I'm interning currently and I noticed that I get frustrated with python because of that.
