/prog/ - Programming

Nice. It would be good to have more life in this board. It's not easy to bring life back to a mostly-dead board. Most programmers on the site either don't know this place exists, or remember that it exists and is dead.

I don't have a clue how that Attention-Hungry Games thing works, but it might be worth entering /prog/ in the next one.

>>5260

It might also be that some of the few who came here stopped because a sticky thread suggested this board was about to be nuked for a whole month, and according to the settings only mods could make new threads, unnecessarily strict rules etc.

There's only a ~1/45 chance of winning attention hungry games per week and it has the adverse effect of attracting shitposters if you do, but it could be useful for a push of awareness. I don't think I'll submit /prog/ to it myself, but feel free to if you want to.

It would be nice if this place was more active, since the start of this year /tech/ has been filled with /g/-types who can't program and instead shit up the board with consumerist shit.

>>5311

I feel you. /tech/ was already filled with idiots beforehand, but it's gotten really bad recently. For what it's worth, I'm monitoring this board. Just start a thread about something you want to talk about.

>gitcoin bounties

what does this look like? can you talk about your workflow for this?

if you find time, a post on some worthwhile hustles like that would be cool (despite it working directly against your self-interest..). I have a lot of spare time and could use some cash or whatever, I'll drop an email if you want

>>5303

oh, and can you expand on

it sounds entertaining yet pragmatic

Newfag here.

Can this help me rebuild my forgotten math background from 0? Third world education more or less didn't care as long as you passed.

>>5307

Yes - there is a section in the guide that specifically addresses this concern. Specifically:

Start now, go fast, and don't look back.

All language's have pointers. Even if A language doesn't expose you to the pointer.

You just hate pointers because you refuse to understand how memory works low level. DUMB ASS HOE

>python without list comprehension or list slicing

it would be so annoying

>>5296

There isn't anything better than these options at least in 8chan. Problem with 8chan is that it's completely under the thumb of goon types, they can shit up every board and manipulate people and the mods into bending to their will and nobody is willing to learn to recognize and ban them.

It's strikingly reminiscent of real world, they're completely ruining our home, but people will defend those guys because they've been manipulated into thinking that unless you let people do whatever they want then you're an evil rulecuck 4chan jew kike femitranny newfag who hates fun and doesn't understand 8chan culture and we need to migrate to a new board that's exactly like /b/.

>>5297

Well, either way this board certainly doesnt suffer from any kind of overpopulation. On topic, a couple of questions:

<Do you use C++ at work?

For me its part hobby part work, graphics programming and geometry processing. Im working towards my Bachelors in CS and wonder if C++ is a good specialization choice, career-wise. I like it for the performance and flexibility, and can‘t really warm up to the other big players like Java or C#, but i have used them. Reading the FQA >>5177, the points make sense, but there isn‘t really a good alternative. Would be interesting however to test if he is right about flawed shared_ptr use and superfluous pass by values outweighing the penalty of a managed language and GC, in the average project.

<Preferred C++ subset

A lot of RAII, shared_ptr and stl containers. Usually not a single new/delete in the entire project, a lot of auto, limited amounts of templates. Little OO and inheritance. Heavy use of ECS architecture, but that is very application specific. No singletons or static initialization at all.

<Preferred and recommended libraries

>cereal - Easy, fully featured serialization, barely any code necessary

>EnTT - Great, very fast ECS with very useful bonus features

>ImGui - Stateless, immediate mode GUI, shit documentation though

Why the unexpected behavior here? Instead of segfaulting it "fails" silently. Please excuse my lack of understanding here.

>>5300

        #include <iostream>
        using namespace std;
         
        void swap(int * p, int * q){
           int temp;
           temp = *p;
           *p = *q;
           *q = temp;  
           cout << "Hello" << endl; //this is the unexpected behavior point; cout does not work if int is passed to int* but it also doesn't just crash or not compile; why the unexpected behavior?
        }
         
        int main(){
           int c = 5;
           int d = 10;
           swap (c, d); // this should be swap(&c, &d) yet this DOES swap the values but does not cout as expected or segfault
           cout << "c is set to: " << c << endl;
           cout << "d is set to: " << d << endl;
           return 0;
        }

It's because you are not calling swap, you are calling

std::swap

#include <iostream>

using namespace std;

std

swap

swap

std::swap

swap

>>5300

You can prove this to yourself by deleting your swap function, the code still does the same thing.

reference manual (asm, c, wireless cards supported by linux, commodore computers) these have the bonus you might actually want to USE it later. a full z80 reference is not very hard to write but it takes some looking around. you can slap together a half-working z80 interpreter in like a week with just very basic c knowledge.

it sounds like you just need a framework so you can just put in empty todo pages instead of content and you're good to go.

can someone explain ALL the uses for the -> operator?

i'm trying to learn OpenGL|ES 2.0 for the raspberry pi and don't really know what the fuck i'm doing besides reading K&R once and the code example here ( https://github.com/Apress/raspberry-pi-gpu-audio-video-prog/blob/master/EGL/window.c ) repeatedly uses the arrow operator from a struct to its members, whereas K&R and other resources I've found say it's only supposed to be used for a pointer to a struct to access members.

so for example, if you have a struct s and a pointer to struct s as ptr_s, and the struct has members x and y, what does s->x even do? shouldn't it only be s.x or ptr_s->x?

>>5286

nevermind, i'm an absolute nigger monkey. the naming conventions are just horrible in this code, it really is the struct's pointer being passed to a different function and then used with the same name as the main struct. global variables can swallow fat loads.

digital mars has FIRE c++ compiler for windows... high recommend it. Everyone @ rockstar games uses it :)

GCC: GNU's C compiler, available for almost every platform, and popularly installed on Unix machines.

Digital Mars C/C++: The hackers at Digital Mars have a pretty rippin' C/C++ compiler for Windows that you can download and use for free, and that will work wonderfully for all the code presented in this guide. I highly recommend it.

VC++: Microsoft's Visual C++ for Windows. This is the standard that most Microsoft programmers use, and I freaking hate it. Nothing personal, but I'm one of those crazy people that still uses vi.

Turbo C: This is a classic compiler for MSDOS. It's downloadable for free, and I has a special place in my heart. (It can't handle the "//"-style comments, so they should all be converted to "/**/"-style.)

cc: Virtually every Unix system has a C compiler installed, and they're typically and merely named cc (C Compiler, see?) Just try it from the command line and see what happens!

Oh and the Zhirkov book is mainly (completely?) x86_64, there are quite a few differences. And '64 has two different calling conventions: one for Linux and one for Windows. They differ in which registers are saved to/retrieved from the stack on function calls.

Ugh what a sad reminder of my unanswered stack overflow thread about an x86 problem I'm having. I opened it an hour ago (https://stackoverflow.com/questions/53967161/segfault-when-writing-into-data-segment-even-though-sufficient-space-allocated) or so and not one answer.

Are there any resources for i960 ASM? A huge stretch I know, but I can find almost nothing. The only online resource is some college project which used CTOOLS 5.0 code to create some sort of network.

>>5255

Well, if you must.. just Wiki the i960, the last external reference listed deals with instruction set.. and then get good at assembly.

https://software.intel.com/en-us/articles/intel-sdm

https://developer.amd.com/resources/developer-guides-manuals/ (scroll down to the "AMD64 Architecture" heading)

These are the official reference documentation for the x86 architecture.

I'll bite. Why? I am fascinated with Terry, love what he did, would love to know more about making ring 0 only OS's work.. but why Holy C? It looks so much like straight C with a ton of exceptions. Why not just use C, like GCC, maybe with some extensions? It would take folks so long to get adept and make programs.

>>5278

He's no nigger, he made his own compiler.

>>5278

HolyC used to be more like C, but due to the need for the language to work as the shell and the main programming language Terry had to modify the way the language was written. Think how he ones spoke about function pointers how he had to find a new way to represent them in HolyC because of the shell. Terry also wanted to use C as the shell because he never really learned the window batch files or the unix shell.

GCC for Terry had couple of problems

1. GPLv3

Originally terry had a loose idea of selling his OS.

2. JIT

As far as I am aweare GCC does not jit compile any languages..

3. The Size

The feature set of GCC very large and the way how most GNUproject software is written. Means that GCC would take up way too many lines of code and thus either fillup or excede the somewahat arbitrary LOC limit that Terry had. Also GCC has dependencies so those would have to be either ported or reimplemented.

4. Format

TempelOS uses a special fileformat that is somewhat similar to RTF called DolDoc. This is what enebles for the system to have a complex HyperText linking system and for the code to have embeded 3D models, sounds, images and so on. It would propably take a while to implement a proper parser for the format in GCC.

The reason I know that you're LARPing is because your uneducated mind is too small to detect instances of parallel computing (i.e. distributed computing) in the real world.

>snake oil

hadoop?

Apply a map to an image. This is an awesome example of SIMD computing.

Anything that's isomorphic to the above example is also a good example, and there are a lot of those.

>>4597

This free CMU book will show you all the algorithms and data structures that can benefit from being run in parallel http://www.parallel-algorithms-book.com/ which is a ton of things

It's certainly not snake oil OP. With multi-core cpus if you don't program intentionally to take advantage of them, then you are leaving a metric shitton of perf on the table. This is currently the best book on the subject in general so I'm shilling it for now.

I suppose that depends on your level of knowledge / experience. It has certainly helped point me in the right direction (TOR/VPNs, GNU/Linux, FSF, /prog/, etc)
