I love rust too. Started playing with it yesterday. "The Rust essentials" book is a nice short introduction.

I like that Visual Studio Code has a god tier plugin for Rust too. Although I kinda miss their lack of syntax checking in the plugin.
Overall, it's quite nice.

A programming language that can only produce two kinds of programs -- empty programs and infinite loops -- is fairly useless. You should add I/O so that you can generate actual computer programs, rather than just some busy machines that crunch numbers and then throw the result on the floor.

I'm emailing RMS and I don't have the heart to tell him "no"

>A programming language that can only produce two kinds of programs -- empty programs and infinite loops
I don't recall posting the formal semantics of my language.
>generate actual computer programs
What the hell is an "actual" computer program?
>crunch numbers and then throw the result on the floor
An empty program can't do that, and an infinite loop "throwing results on the floor" would be a self-contradiction.

i started studying pthreads. this is my first program

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void *add_elem(void *line)
{
        int *line_pointer = (int *)line;
        int accum = 0;
        for(int i = 0;i < 3;i++)
                accum += *(line_pointer+i);
        *line_pointer = accum;
        pthread_exit(NULL);
}

int main(void)
{
        pthread_t thread;
        int matrix[2][3];
        matrix[0][0] = 1;
        matrix[0][1] = 2;
        matrix[0][2] = 3;
        matrix[1][0] = 1;
        matrix[1][1] = 1;
        matrix[1][2] = 1;
        int rc;
        rc = pthread_create(&thread, NULL, add_elem, &matrix[1]);
        if(rc) {
                printf("ERROR; return code from pthread_create() is %i\n", rc);
                return -1;
        }
        int *line = matrix[0];
        int accum = 0;
        for(int i = 0;i < 3;i++)
                accum += *(line+i);
        *line = accum;
        if(pthread_join(thread, NULL)) {
                printf("error joining thread\n");
                return -1;
        }
        printf("line 1: %i\nline 2: %i\n\n", matrix[0][0], matrix[1][0]);
        pthread_exit(NULL);
        return 0;
}

it sums line 0 and 1 and puts the result on the first element of each line.
if i wanted to return accum instead of putting in the first element, how would i do that? how can i get the return value?

So I want to create an APP

Do I begin with learning bineary?

it isn't elegant but make a struct with two elements: one being the address of the segment of the matrix you want to operate on, the other being an int.

Don't get me wrong, I'd love VP9 support, but you'd then be stuck in a hell of broken support or enforcing a specific library version (which is too much for most people). In any case it's too much work and worry for the site ops.

>>60090113
Writing single characters or whatever at a time to a file is extremely inefficient, so they are buffered and only get written to the file when the buffer is full, or you explicitly flush it.
stdout is typically line-buffered, which means that it will write to the buffer when it encounters a newline character. You didn't write a newline, so it didn't get flushed.
If you're ever going to write something that you want to be displayed immediately and you haven't printed a newline character, you have to explicitly flush it.
None of this is Rust specific. Basically every language does it like this.

>>60090205
>write to the buffer when it encounters a newline character

I fucking hate this.
Just because you work with C doesn't mean you know about optimizations. The problem is generally not the calls themselves (although for cases where you do operator overloaded functions it will be) but the constraints having the compiler restrict itself by calling your function to do the transform.

Inlining is regarded as one of the primary optimizations compilers do because having inlined something implies so many other optimizations. Not having inlined something implies a lot of optimizations missing.

Why do programmers so often feel justified in speaking outside their expertise? Nobody who just 'writes C' should ever consider themselves performance experts of any form before they've at least profiled their code.

The example I posted turned out to be a 2x speed improvement. After further investigation where a call to the standards floor wasn't inlined it was all in all more than a 10x improvement. Yet this motherfucker likes to speak out his ass and claim its nothing.

How you implement them is up to you. There's millions of implementations for the popular ones floating around if you want to grab them.
https://en.m.wikibooks.org/wiki/Algorithm_Implementation
I like this one.

But for implementing an algorithm you just put what it describes to you into code. Then you improve it if possible.

>>60092953
maybe you are right in what you say,
but you ought not have said it as it was a wasted post due to it not being programming related.

however, by talking about a dpt topic down here, it's a nice loophole.

for example:
despite you all hating OOP, that fact is that OOP is what runs our modern world.
sure, you have specialized cases where you may need to write binary instructions for some scientific equipment or something. but for the vast majority of consumer products, OOP = win.

>>60093036
Anon you're not framing the OOP-discussion you're trying to start here in a way that facilitates discussion. At the very least you could start with the leading question 'If OOP is so bad then why does everyone do it?'.
And there's plenty of ideas surrounding that.

Also your idea of non-OOP suitable cases indicates that you don't have much experience with regards to OOP and its alternatives. Which makes arguing with you like explaining science to someone who believes everything is random. It's a lot of frustrating work. And you probably won't gain anything from it.
