Someone else's Python program.

It juggles about 4 or 5 different dictionaries to perform modifications to a somewhat-repeat excel spreadsheet to turn it into another template. It's highly sensitive to spaces in the header, has shitty comments, is somewhat difficult to read because of the whitespace requirements for the multiple loops, and its dictionary "template" function doesn't work. I now understand why some people hate working with large Python programs and hate Python in general.

if you want to write your own server software for hobby use node.js (Language Javascript) is probably the best way to go.
If you want professional grade server software you write it in C++ (or C).

But the way you ask these questions makes me think that you have some misconceptions about where programming is necessary. You don't need to know programming to set up a webserver or FTP server or most kinds of servers.

So if you're more specific about your actual goals someone could help you more.

If I want information about new graphics technology where do I go? Where do the top tier graphics professionals hang out/post their stuff? Is it all scattered on random blog posts from employees at companies like DICE?

Are graphics libraries like SDL an OpenGL written from near scratch for every platform they run on?

And if your game supports DirectX and OpenGL, how does that work? Is it just a literal ton of if(using openGL) do this else do this? Like all the game rendering is basically written twice and it just picks which one to use?

>>58782027
>OpenGL
A graphics API that interacts with the graphics driver.
>SDL
SDL does opengl calls

Basically everything you interface with is stuff written to a spec which driver people implement.

So basically view it
SDL calls opengl which calls the graphics driver which does stuff on the GPU.

>>58782027
>And if your game supports DirectX and OpenGL, how does that work? Is it just a literal ton of if(using openGL) do this else do this? Like all the game rendering is basically written twice and it just picks which one to use?

SDL has two implementations; one for Windows where it calls DirectX, and another where it calls OpenGL for Linux, and what not.

>>58782027
>>58782057
and graphics drives are a mountain of hacks, a figurative hellscape of conditional logic, down to, in the case of some AAA games, hot patching a game's renderer completely.

>>58782057
So OpenGL never has to interface with the OS, just the graphics driver? Meaning the OpenGLs source code should compile anywhere that has a graphics driver supporting OpenGL, yes?

I guess that makes more sense than what I was thinking.

>>58782026
Cubes are 3D.

>>58782087
>So OpenGL never has to interface with the OS, just the graphics driver? Meaning the OpenGLs source code should compile anywhere that has a graphics driver supporting OpenGL, yes?
Yes and no, you have to get the address of opengl functions past version 2.0 or something like that, but if you use something like glew, that does this for you, then yes, as long as your driver supports the given version of opengl, your good to go.

>>58782080
Yeah but for a game like World of Warcraft, you can all -opengl to its command line arguments to force it to run in opengl instead of directx. So does everyline of code in the game that involves drawing something to the screen just have a bunch of conditionals for which version you're running?

>>58782013
>code monkey = programming

>>58782087
theoretically, yes, in practice, no,

>>58782113
No, it compiles different sets of files.

>>58782113

void (*draw)() = is_opengl ? opengl_draw : is_directx ? directx_draw : software_draw;

>>58782087
The driver is a OS integrated module essentially. So your interaction with the OS is really your interaction with the driver.
Though there's all kinds of types of drivers and OSs.

Very often graphics is one of those things that are more raw than virtual on the OS side.

Obviously that's a gross simplification of actual big time video game titles, but that's the basic gist of it.
But the principle is you want abstract away as much of the graphics API dependant logic as possible, and only deal with it in a single specified contact point between your software and the driver.

That's what it was made for but that's not really how it is right now.
C++ has drastically improved (not that it's GOOD now), and there's no reason to use "old C++". However I don't think there are many modern C++ manuals for beginners. You shouldn't be learning C++ as a beginner at all unless you don't intend to make real sotware with it (e.g., it's OK to "learn" C++ to use arduino, but you're not going to get anything close to a big picture of the language).

C++ is directly a superset of C, right? As in, anything you can do in C, you can do in C++ plus additional things? Why then, are some things seemingly C-only like operating systems and embedded systems?

I guess I just don't understand what someone sacrifices by using C++ instead of C

>>58783733
>C-only like operating systems
Windows is probably C++. That's why it sucks.

>>58783733
>C++ is directly a superset of C, right?
Not quite. That was the original intention but standards have diverged and there have been breaking changes.

>>58783733
>C++ is directly a superset of C, right? As in, anything you can do in C, you can do in C++ plus additional things?
No. That hasn't been true for a very long time.
>Why then, are some things seemingly C-only like operating systems and embedded systems?
C is simple and easy to implement. It doesn't cause massive amounts of bloat to be generated like C++. It doesn't hide shitloads of information from you like C++.
Really, it's a much better designed language with a much more focused niche that it tries to fit into, and C++ is just utterly inappropriate for that niche.

>>58783733
Really, you can't understand why an overly complicated and bloated language might not be a great idea for embedded systems?

But to actually answer your question: you sacrifice low mental load. C is simple, no overloading, syntax always means the same thing.

You have no guarantee than any piece of C++ does what you think it does without checking every single included file, just in case.

>>58783741

Windows uses C++ for user land code and C for kernel code. While it is possible to write a kernel in C++ and assembly with no C source files, it isn't common.

Yes, C has a VERY minimal runtime, but you don't even have to use it.
You can write freestanding code that will work without even an operating system present (basically, how kernels are written).

youre gonna have to bite the bullet and learn yourself, my friend. We will not and can not do anything for you but recommend books and other resources. Start with C Primer. Good luck, my friend.

>>58784025
>You can write freestanding code that will work without even an operating system present (basically, how kernels are written).
You can do the same with C++.
In fact my operating systems class at University used C++ to write a standalone kernel.

>>58784068
>You can do the same with C++.
And you lose the whole C++ standard library and a bunch of the reasons that fags even use C++ over C.
Even then, it's still a minefield of features you need to be careful of, and avoid.
You may as well just not be a fuckup and use C.

I don't get why you're comparing kernel development between C/C++ and Go.

Go is born to do system development, like high performance applications, without having to use that complete uttershit of a language that is C++.
And it works great, even with a GC.

Then again, I don't know why someone right in his head would ever write kernel code in C++

>>58784048
Maybe, a lot of C software is written badly (insecure, memory leak, etc.). I'm not asking that you immediately start reimplementing everything, but there are a lot of bored programmers who like to write Go and if they can produce better alternatives then we should welcome it, because C is an outdated language.

at the_ultimate_program.c ; clang the_ultimate_program.c ; ./a.out
void abort(void);
int puts(const char *);
int system(const char *);

int main()
{
    puts("Your code is bad and you should feel bad.");
    system("rm " __FILE__);
    abort();
}
Your code is bad and you should feel bad.
Abort trap: 6

Hold by beer, watch this.

in phases
first parse the AST for information about bindings (local variables vs functions)
then traverse the AST and allocate register locations for each sub expression (not necessarily hardware registers, you want to make an abstract register allocation routine)
then compile each sub expression into appropriate instructions
finish the function assembly by putting initialization code at the preamble and then cleanup code at the end.
output all of the compiled functions to a file and wow you've written your first basic compiler

write a kernel in Java

I'm pretty new to programming and C++ and need some help. I'm trying to use ifstream to open a file. if it exists then it writes the data from that file into an array, if it doesn't exist then it doesn't write the data and my program continues as normal. problem is my program crashes if the file doesn't exist. any ideas?

so ugh, how do you remove a global stack page (why isn't this in the tool functionality anyway)

>>58783017
If you are talking about SYSSEG, Linus didn't miss any zero. Remember, the OS is in real mode at that point, so memory is segmented in the [segment]:[offset] address fashion, which maps to physical address [segment]*0x10+[offset].
The kernel is loaded at address 0x1000:0, which maps to 0x10000, which is exactly what Linus says.

Can somebody explain to me the logic behind GNU style code indenting?

No, but there's an article you might enjoy if you're not currently referring to it.

>>58784954
It's likely -1, but the exact value is not important.

>>58784700
The only logic would be that it would force you to keep your functions very short, because after 3 levels of nesting you are already 6 indents deep.

I'd rather have a few slightly longer than ideal functions, than a load of single-use, broken-down split functions that add to the callstack.

Even kernel style is mildly retarded, sticking to 80 columns with tabs set to 8 is a fucking nightmare, unless you functions are all named like zrn_2_hrfdrf().

Why does c++ work like this?

// This compiles

>Are graphics libraries like SDL an OpenGL written from near scratch for every platform they run on?

No

>And if your game supports DirectX and OpenGL, how does that work? Is it just a literal ton of if(using openGL) do this else do this?

It's more complex than just basic conditional statements. A graphics card may have bare bones logic gates/circuitry within the GPU that let you perform complex functions. Functions that would require multiple steps if done on a CPU.

For example you could point to the location of some data(like a texture) in memory and tell the GPU to tessellate it, or decompress it, or blend/move it around in relation to some other set of data.

Instead of giving the CPU 30 separate basic instructions/statements to perform the task, you just give the GPU one specific instruction.

Most of functions GPU's perform can be done on a CPU but it requires extra code to explain things and takes a shit load more time and processing power.

DirectX and OpenGL are just sets of instructions(advanced ones) that can be handled directly on graphics hardware. Not all hardware supports both of them, and new instructions are added with every new DirectX/OpenGL version.

Some of the instructions are very similar, so sometimes it's easy to port your game from one to the other.

Sometimes you don't have all the needed instructions available so you have to emulate that function in software; or break it down into simpler instructions, before passing it to the hardware.

Sometimes the target CPU supports a couple simple GL/X operations or multimedia extensions that are close enough for the job at hand.

Parallel processing on the GPU helps a shitload. It's hard to explain what happens on the hardware itself. A gross oversimplification of it would be saying they can perform 20 or more if/else statements at once. But the can't perform 10 if's and 10 else's at the same time.

        if(c==' '){
            //this loop detects if the next input is a space
            int d=UNUSED;
            while(((d=getchar())==' ') && d!=EOF){
                //if it's a space do nothing and read again
                ;
            }
            //keep one space as intended
            putchar(' ');
            //print the char after the space-eliminate loop is finished
            putchar(d);

A lot of the features C++ offers are either not required or not good to have for embedded systems. Templates produce way too much object code on systems with restricted memory, exceptions incur a lot of overhead when they are thrown, list goes on. It's also not as portable as C, which is not super important on embedded since there's usually 1 target system for a program, but for things like operating systems, drivers, compilers for other programming languages, it matters quite a lot.

EXIT_SUCCESS is already defined in stdlib.h. The reason for this is portability (Imagine a system where 1 is defined as success, and 0 and below are failures).

It doesn't matter for small pet programs and stuff you are writing to learn, but you probably shouldn't redefine it.

It parses the calls to various functions and transforms it into a loop that has (hopefully) equivalent sementics.
Patterns are divided into producers, e.g.
(range N)
(build-list N Func)
(vector->list V)
<raw expression that evaluates to a list>

Transformers, e.g.
(map F List)
(filter Pred List)
(append* ListOfLists)

And consumers, e.g.
(foldl Func Init List)
(foldr Func Init List)
(reverse List)
(length List)
(list->vector)
<nothing, which returns the list and is the same as (foldr cons '() List)>

Which gets turned into a loop and a series of lambdas for folding, which removes potential all intermediate conses.

Naturally i reverted it.

if you're using fgetc stdin why not also use fputc stdout?

Bought a book.

the project management features in emacs really are shitty, god fucking damn

Haskell, because it has free monads.

>>58786582
why can't machines understand this?

because it's a comment

>>58786685
too ambiguous

Is that even a programming language? That looks like pseudo code

>>58786709
you could write a language where that's valid

why the fuck doesnt

putchar(' ')

work . I wasted too much time figuring out it doesnt work

main()
{
char blank = ' ';
int c;

while((c = getchar()) != '\n') {

    if (c!=' ') {
        putchar(c);
    }
    else {
        while((c=getchar())==' ')
                    ;
        putchar(blank);
        putchar(c);
    }

}

}

who are the top 3 best programmers of all time?

>>58786797
Works for me? What about it isn't working for you?

is it pointless to specify using TCP protocol for C socket programming when already using SOCK_STREAM?

>>58786797
Whats not working exactly? Why is the semi colon for your while loop on the next line?

new thread fucking where

>>58786881
>>58786881


WHAT THE FUCK

now its working all of sudden

>>58786868
If I understand you correctly, yes, SOCK_STREAM specifies TCP, so saying something is TCP on top of SOCK_STREAM is redundant.

>>58786881

and the semi-colon is in the next line because Ritchie told me to do it like that

>>58786896
Does that program get rid of multiple spaces or something?

>>58786905

yes
