>Which one is more useful?
Python, but learn C If you want to learn programming.

please rate my fizzbuzz

#include<stdio.h>
#include<pthread.h>
#include <unistd.h>
pthread_mutex_t lock;

void* fizzbuzz(const void* n)
{
    pthread_mutex_lock(&lock);
    int i = n;
    if(i%15 == 0){
      printf("fizzbuzz\n");
    }
    else if(i%5 == 0){
      printf("buzz\n");
    }
    else if(i%3 == 0){
      printf("fizz\n");
    }
    else
      printf("%d\n",n);
    pthread_mutex_unlock(&lock);
}
int main(void)
{
    int threads = 0xFF;
    pthread_t thread_id[threads];
    int i;
    int j[threads];
    for(i=1;i<threads;i++)
    {
        j[i] = i;
        pthread_create (&thread_id[i], NULL , &fizzbuzz, j[i]);
        usleep(1);
    }

    for(i=1;i<threads;i++)
        pthread_join(thread_id[i],NULL);
}

>Python, but learn C If you want to learn programming.
Would I not learn programming from Python?
Okay, I'll get the meme C book

>>58453987
Learn Python first, then C to better understand how things work under the hood, and in case you need performance.

>>58453817
pls respond

>>58454089
Assembly programmers

>>58454035
You would, but you'll miss out on all of the low level concepts such as pointers and addresses.

Also C is the lingua franca of computer science. If you're a programmer who doesn't know any C you won't even be taken seriously. Again, if you want to program for the sake of making simple scripts and small projects then look no further than Python, it's the best language for "getting shit done". But if you want to become an actual programmer then you must learn C.

>>58454017
>doesnt initialize mutex lock
i'd say it's about deadlock/5

>>58454141
I would say that C is the lingua franca of software engineering, but not computer science.

ok, playing music works now

now i just have to implement proper pausing (instead of stopping), a seek bar, skipping to next/previous, and so on

and of course improve looks

>If it's stupid but it works, it's not stupid.

is this valid in programming? do you care?

Fizzbuzz is too easy.
Everyone should be able to implement a naive substring search.

If not, you shouldn't be allowed near a computer.

>>58454119
Yeah no. GCC and other compilers are so advanced today that there's no point in programming in Assembly except for very niche situations. In general properly written C/C++ code will run just as fast.
If the top of the food chain is simply the most low level language then it stops at C, everything else is a meme.

>>58454228
it is completely valid unless it's so stupid it slows everything to a crawl (like doing intense i/o in every iteration of a loop or something equally retarded)

i noticed that many newbies are afraid of sharing their code because they're not confident and think that people will laugh at their mistakes, but if a program does what it's supposed to do and consumes a reasonable amount of resources, and is moderately fast, it's great in my book

>>58454234
A search for... all the substrings in a string?

is using multiple contexts with opengl useless except for data transfer and having multiple windows?

like if you want to render to a shared texture (let's say it's an expensive shader and you don't need the result immediately) and the opengl implementation is single-threaded then it will just be the same as (or a bit slower than) doing single-threaded rendering?

>>58454266
Probably means if string X is in string Y

>>58454390
Shits easier than fizzbuzz

>>58454157
You mean UB/5

>>58454141
I agree, but Python is still very useful and more friendly for beginners.
It can also introduce them to OOP and functional programming once they have a good grasp of procedural programming.
The best thing is to learn both. If you aren't familiar with at least 3 languages using different paradigms and features, I would say that you aren't a real programmer.

>>58454251
Audio devs often use SSE/AVX instructions and the like to tighten their processing loops, and I'm sure game dev do the same, but yeah, it's generally just inline assembly in the context of a C/C++ program.

  int len = strlen(toSearch);
  int termLen = strlen(term);

      if (term[0] == toSearch[i])
        {
          bool found = true;
          for(int x=1; x<termLen; x++)
            {

>>58454466
if you found it already, just return true immediately, you don't need any breaks in that loop.

>>58454492
>>58454597
Thank you bros, next week I will probably post some binaries and code too

>>58454640
actually nvm you need to check the whole thing and not return immediately so keep it as it is

>>58454234

const char* strstr(const char* haystack, const char* needle) __attribute__((leaf, nonnull)) {
    size_t i;

    for( i = 0 ; *haystack && haystack[i] ; haystack++ )
         for( i = 0 ; haystack[i] == needle[i] ; i++ )
             if( !needle[i] )
                 return haystack;

    return NULL;
}

>>58454466
the outer loop should go to len - termLen so you don't go out of bounds

>>58454656
Fug.

         for( i = 0 ; haystack[i] == needle[i] ; i++ )
             if( !needle[i + 1] )
                 return haystack;

>>58454234

bool is_substring(char* sub, char* str)
{
    char *tmpsub, *tmpstr;
    for(;*str != 0;str++) {
    if (*str == *sub) {
        tmpsub = sub;
        tmpstr = str;
        while (*tmpsub != 0) {
        if (*tmpsub != *tmpstr) goto resume_main_loop;
        tmpsub++;
        tmpstr++;
        }
        return true;
    }
    resume_main_loop:;
    }
    return false;
}

This is very ugly, but it works

How would you reconcile the overlap between regex and file globbing?

>>58454728
>goto resume_main_loop
How about just continue?

>>58454769
Didn't see inner loop because your indent is shit.

>>58454769
Because it would return true otherwise, I don't know to structure this in another way.
Sorry btw for the fucked up indentation, my Emacs config use tabs instead of 8 spaces for some reason.

>>58454466
it should only return if found, otherwise it should keep searching

How would one loop through an int value in c#?

Please show the implementation or just describe how you would do it.

imagirlbtw

>>58452653
And once again, this doesn't do what the example does and is still worse

>>58454917
If you mean look at each digit in a multi-digit int, like 12345, just take % 10 and store the answer, divide the number by 10, rinse and repeat until the number is 0.

>want to make toy prog language
Should I call it EvilC?

>>58454993
If you take modulo 10 of a number 12345, you get 5. If 12345 is an int as you said, dividing it by 10 will give you 1234. If you take modulo 10 of 1234, you get 4, and so on and so forth until your number is 0 and you break the loop.

>>58455058
It gives you the remainder of a integer division.

>>> print([n % 3 for n in range(1, 7)]) # n = [1..6]
[1, 2, 0, 1, 2, 0]

#include <stdio.h>

main()
{
    int c = EOF;

    printf ("%3d\n", c);
}

Is this faulty in any way? Will the concept of EOF become more clear as I progress through the meme book?

Is modulo useful for anything other than clamping a number to a certain number range?

def get_img_links(self, thread, _res):

# File = high, width and file
board = basc_py4chan.Board('g')
board.get_thread(get_id(thread))

links.append(file)
zsfile[post] = File(threadid.posts[post], file)

>>58456036
fucking idiot, non-trivial programming tasks require actual problem solving and writing the implementation yourself, not just calling a library function, but such tasks are typically much too big and hard to fit in a simple exercise, so you start with things like fizzbuzz or substring search as a beginner's learning exercise or for a job candidate to show that they have a basic understanding of the job they're applying for

alright so I've been breaking my head over this for too long now:

I am building some binary tree, but I need to do it concurrently. The way it should be done is that I start with the root node, then continue building the left subtree on the current thread and split off a task for the right subtree. There's a thread pool that I need to distribute the tasks to. So I used a concurrent queue in order to pop and push tasks from multiple threads.

The problem is managing the threads. I need to somehow have the threads keep consuming tasks from the queue, but a consumed task can itself add new tasks to the queue, so I can't simply quit when the queue is empty, as new tasks may still be produced, which the worker threads then need to eat up again.

I've been thinking about a solution with some waiting/signaling and semaphores to keep track of the amount of busy threads (empty queue and no busy threads would be a termination condition), but I can't quite figure it out.

Is there a common pattern for problems such as this? I'd love a neat solution.

Specialise in Web Assembly.

I'm trying to figure out why the output of Racket's inflate/deflate isn't the same as the output from zlib-flate. Data compressed by one cannot be uncompressed by the other and it seems as though the difference is two bytes: zlib-flate will create compressed data with

#x78 #x9c

at the beginning while Racket does not have those two bytes. Removing them before sending to Racket for processing will make Racket happy and adding those two byes to Racket's compressed data will make zlib-flate happy.

I'm just really confused as to why there's two bytes missing from Racket's compression functions. There might be something that's different between the two at a more fundamental level, but I don't know DEFLATE well enough to go into either and look at the source.

I plan to make an app where I can track all the food I buy by scanning it and entering an expiration date. The app will notify me when the expiration date is arriving and might also provide some tips when connected to the internet.

In general, the more IO there is, the less beginner friendly something is. This has to:

Where I live you're better of specializing in C#.
Most development here is being done for businesses, which are using windows ~80-99% of the time, so .Net is pretty much a perfect match for everything you want to do.

Hating any programming language (The whole C# vs Java thingy) is childish and should not be promoted by professors. They should be ashamed when calling themselves software developers / engineers / whatever and start teaching unbiased lessons.

>>58458169
>people in the industry avoid microsoft's platforms as much as they can
Talking out of your ass.

Active Directory, Exchange, and SQL Server are ridiculously widespread among businesses, particularly the SMB world.

Why do you think Oracle is any better than Microsoft?

At least Microsoft is beginning the process of making all the dev tools free and open-source. Hell, .NET is first-class tech on Red Hat Enterprise Linux now, and Canonical (Ubuntu) has joined the .NET Foundation.

It's odd though. If you would have told me in 2008 that Microsoft was going to be actively contributing to and advocating FOSS, I'd have called you crazy. It makes sense, though, considering Azure is growing insanely fast, so if they open up their ecosystem, more will want to use it.

You should learn everything you can, and expose yourself to many languages.

That being said, C# is huge in my market space, so I'm glad I know it. Comfy language, too.

If you want exposure to the most possible jobs, then learn Java. C# has a fuckton of jobs, and is generally more enjoyable to work with, in my experience. C, C++, and Python all have many jobs, and are very common as well.

You do you, man. Do some research and stick with what you like.

Hello /g/entoomen. I seek your wisdom concerning books for a beginner programmer.

My end game: AI and/or robotics (from industrial to whatever) from a design standpoint (management or prototyper etc)

My experience: Currently studying Electrical Engineering Technology in College (hands on engineer I guess? Between an industrial electrician and full blown engineering). I've taken a few new robotics courses working with Ardunios. Gonna get PLC exp soon.

I'm decent at math, but something I'm working on to improve, slowly working through Spivak's Calculus. I have some previous experience coding, I find I have a good head for programming, comes relatively easy to me and I'm anal about organization and neatness in code. I like to get creative with solutions.

I have a few books in mind I also want to pick up:
Code Complete 2nd ED
Head First Design Patterns Into Design Patters: Elements of OOP
Algorithms Unlocked Into Introduction to Algorithms (Thomas H. Cormen)
Code: The Hidden Language of Computer Hardware and Software
Structure and Interpretation of Computer Programs
Refactoring: Improving the Design of Existing Code

Took these books from the highest rated/most recommended lists, are they memes? Worth my time?

I'm looking to start learning C, Python, Java and get into R, Lisp, C++ later on. I guess I'm asking you guys what are some solid books, in your opinion, that I can get to start learning the first 3 languages. THANK YOU IN ADVANCE.

So I'm trying to fix Unity's totally fucked occlusion
The matrix I'm dealing with is the one in green. For some reason, as the near clipping plane gets farther from the camera, this fucking matrix seems to scale, translate, or something else the same distance away from not the camera, but the camera's near clipping plane.

Two questions.
1. Does anybody know the exact semantics/breakdown of how an "occlusion matrix" would work? It's not a projection matrix, as when I assign the occlusion matrix to the projection matrix everything gets fucked
2. Does anybodyk now what kind of matrix math I'd need to fix this? It's even worse with oblique frustums, causing the side that's moving to scale its distance at the distance it should ^ 2, which causes an invalid matrix incredibly quickly

I actually wrote an email to Stallman asking him to recommend me a decent free program for editing small text files quickly and he said GNU nano. What did he mean by this?

However I dont write java, depending on what kind of code you're cranking out maybe an IDE would be less stressful to learn. If you need some corporate-bullshit-level build system or 2million LOC codebase managament, maybe one of those would be better. Intellij IDEA would be my first suggestion in that case. It has a built in plugin that emulates vim binds and I've heard it has one for emacs keys too.

that's me, why are you asking?

why do you have a zizek avatar ?

What the fuck? That's my post the i posted here: >>58459333

>>58459768
Exactly what he said. Nano is great for editing config files and such.

Given a list of numbers,
find the arithmetic mean of the numbers,
reading the list only once and using O(1) memory

The only thing that could change is if moneyInBank is 0, and it's going to stay 0 with or without your change.

You are not getting hired with such code.

Given a list of numbers,
find the arithmetic mean of the numbers,
reading the list only once and using O(1) memory

for each_index in list_of_numbers:
    list_of_numbers[0] += list_of_numbers[each_index+1]
    if (length(list_of_numbers)-1 == each_index):
        return (list_of_numbers[0] / length(list_of_numbers))

>>58460164
>>58459955
to clarify my solution, only the memory need to store the list of numbers to be calculated is used. no other memory is used in this solution
>inb4 cpu stack memory. Im not giving an assembly language solution.

How do I calculate the mean of a derivative function without triggering the arithmetic boolean loop in the core? I need to shut down the proxyguard in a vpn

mean lst = (foldr (+) 0) lst / (fromIntegral . length) lst

The first step is to read the question.
The second step is to understand it.
The third step is to attempt it.

Where did you go wrong?

This will return (either true or false) if first character matches regardless of whether the rest of the characters match.
