Thinking of picking up my old project: automatic generation of beatmaps by using beat detection. To make my live easier, I'll be using mpg123 and kissfft. Even better would be if there was a beat detection library available for C or C++.

I actually have a funny story about this: A professor of mine was explaining threads, and noted that some people did not like the master/slave terminology in programming, so maybe he should use primary/secondary or something else.
Then he smiled at us and kept using master/slave the rest of the semester because he just doesn't give a fuck.
i mistook that D programming thread for a /dpt/ thread.
so here is my question.
I am using C#.
i would like to know whether joining multicast group could be programmed in a way so that the message you just sent to the group doesn't end up getting recieved by your listener thread as well.
is there some form of ID that is already set?
or should i be working on some type of identifier byte at the start of each message and only display those which don't share your id?

>>51707421
this is the daily programming thread, not the D shill thread
I'm trying to implement a multiplayer mahjong network, but i'm already at an impasse.
I'm wondering if I should implement an actual starting pool, pick a random position, file it in a queue randomly and use that queue to fill the walls ?
Or should I just randomly put them inside the wall directly?
It's the first time working on a game, but I want the internals to be easily adaptable

Slowly making progress.
I finished link-layer addresses/broadcast and I started working on packet dissection for my network stack tonight.
I'm not sure yet, but I think it's best to have a flat list of all headers like [EthernetHeader, IPv4Packet, UDPPacket] , instead of a nested design.
Luckily distinguishing between 802.2 LLC and regular 802.3 frames isn't that hard, since EtherType values are all > 1518 (max MTU).
Meanwhile I'm still thinking about the filter subsystem and where to put the handlers.
I'd like to get some feedback, but no one in DPTs before nor anyone IRL thinks it's an interesting project it seems.
If this is the /dpt/ thread, then why are most of the posts about whether or not this is the real thread?
My friend function can't access the class's private member. I thought they could? They're in the same namespace and that's the only answer on SO.//a.hpp
namespace dpt {

int private_b;
};
}
//a.cpp
namespace dpt {
int func(A& a) { a.private_b = 2; }
}

I have a question about instancing vs geometry shading. Say I have a circle and I want to move it (0.1,0.1). With instancing would I have to adjust every vertex or is there a way to just change a single vertex like with geometry shaders?
>>51708230
Each instance would have an offset, and in the vertex shader you'd use it to transform the position.
>>51708248
So if I wanted to rotate a square I would be able to just rotate say, one of the corners which I have defined as the offset?
>>51708298
What? You're not making any sense.
All you do in instancing is provide extra data to the vertex shader that is "per-instance". You can then use that to do per-instance transformation or whatever.
i want to learn a new language, but i just keep going back to python.
every time i'm wondering how the fuck i'm supposed to implement a certain feature or write something a certain way, i just redo it in python and it makes so much more sense.
>>51708320
I'm trying to discern why I should use instancing over geometry shading. I don't know anything about instancing.
>>51708367
blub paradox
>>51708368
I already told you. It's faster and expresses intent better.
One specific example would be providing a different model matrix for each instance, instead of using a uniform model matrix. By supplying N different model matrices and drawing N instances, you can draw N of the same thing, with different transformations, very fast.
>>51708402
Alright but what I was really asking is when I have to transform a shape will I have to change literally every vertex of that shape individually. When I want to rotate a shape around a point will I have to rotate every vertex around that point.
>>51708393
interesting read. i'm definitely a blub programmer.
i need to shake this blub somehow.
>>51708450
Yes, but it's all happening in the vertex shader. It's much faster to draw N instances at once than to do N uniform changes and draw calls, one for each instance.

That'll teach people to manage memory properly
>>51708450
you're severely overcomplicating the simple act of moving a mesh around a scene, unless im missing something here. your mesh should be stored as a collection of vertices in model space (i.e. origin of 0,0,0), then you store the mesh's location in world space (i.e. your cube is located at 3,6,0 in the scene). when you pass your vertex position to your shader you just add your world position to that vector to offset it. you don't need to fuck about with geometry shaders and instancing doesnt make a difference.
>>51708607
It kind of does make a difference because I don't want to fuck around changing hundreds of vertices whenever I want to rotate a sphere.
>no traps again
I definitely could use a hand or two coding this thing. If anyone is interested, that is...

the mesh's location/rotation/scale in world space is all that changes

Literally everything in 3D rendering involves doing shit to hundreds of thousands of vertices at a time. That's what GPUs are really, really, REALLY good at.

So how do you do it without using winapi...
So I'm writing a blackjack program in C++ and I'm figuring out the odds of a computer drawing a card with a certain hand. So for example, if the two cards add up to 11, there is a 100% probability that it will draw another card. If the cards add up to 21, there is a 0% chance that it will draw another card. All card sums between 12 and 20 have a special probability.
How do I hand the if statements? I don't want it to look likeif (sum <= 11) { }
else if (sum == 12) { }
else if (sum == 13) { }
I know I can rearrange the order of the statements to change the runtime, but essentially I'm wondering if there's a better mousetrap for handling a lot of if statements. I'm not that experienced.

>>51709298
python or C
or download SICP and watch all of the MIT opencourseware on it
>>51709396
MIT courseware is a fucking meme.
It's way too theoretical, it's like electrical engineering-tier instead of learning programming.
Sorry senpai
>>51709298
My vote is for C.
You should get a book but you can learn a lot of beginner stuff from online tutorials. About a million different YouTubers have C Programming Tutorial playlists which start with installing the program and end with intermediate stuff.
Also to the rest of /g/, is there any reason why a person should learn C before C++? My sister wants to learn programming early and I'm half tempted to start her on C++ because I'm most familiar with it.
>>51709409
lol just kill yourself my man
>>51709298
java
https://docs.oracle.com/javase/tutorial/
C++ if you want to be more "hardcore" from the start
http://en.cppreference.com/w/cpp/language
absolutely stay away from:
>python
>haskell
>lisp
>javascript
>php
and some others but those are the worst
>>51709425
Stay NEET my good man.
I'll be copying public code and getting faggots on stackoverflow to do everything for me LOL

Must've not heard of PHP7 then huh

If she's any serious about it, start with C. It's less language to learn.

>>51709298
I think im gonna go with c but i have no knowlage about programming so what exactly is the best way to start
>>51709474
imo learning c++ is worthwhile because of OOP which is an important topic to cover. not that it would be much work to transition from C to C++, but imo she should just start on C++.
>>51709523
on the off chance you're not just trolling, i truly feel sorry for you

>>51709524
google "c tutorial". its literally that easy. you're lucky to be living in a moment in time where you can learn virtually anything within minutes online, so take advantage.
>>51709538
You don't start with OOP, and you can do OOP in C, not that I would have a beginner do that.
Mane, collision detection was easier than I thought. Still need to work out radius as you can see.

No you cannot do object oriented programming in C.
It does not exist.
>>51709582
true, but its an easier transition than having to go from C to C++ just to understand OOP.

I suppose that's the case. You can teach imperative programming before introducing classes in C++ too, so I guess it works. "cout <<" is going to be hard to explain, though.

The only thing about his indentation that looks fucked is the prints, which I would suspect he has line that so that he can easily identify his debugging code when he goes to remove it.

How do you interact with the OS if you don't use Winapi?
LMAO the things you autists post don't even make sense, get back to ricing arch linux
>>51709842
1) MinGW uses winapi
2) If he's using windows, and you're the one bashing him, why are you the one telling him to get back to ricing arch? Wouldn't that be you in this situation?

>Why would you choose now of all times, when Microsoft is literally walling off Windows to squash third party support
Why wouldn't you choose now of all times, when Microsoft is literally FOSSing their languages and tools to encourage third party support, to become a windows developer?
It's literally the best time it's ever been to be or be interested in being, a windows developer
What's the point of abstract classes without a single pure virtual function? Can't I just inherit from a normal class? Sepples btw.
>>51709973
This...
.net is becoming actually good
>>51709995
It's not an abstract class if it doesn't have any pure virtuals. In fact, the only thing that can make a class abstract in C++ is the presence of a pure virtual.
>>51708807
no g is into traps. also cross dressing makes you program better
>>51709871
MemeGW is le compiler.
That doesn't even make sense... How would you be able to interact with the OS and hook processes without "using windows.h", as he said?
Do the processes magically hook themselves?
>>51710010
I thought just having any virtual function made a class abstract. If that's not the case, then that makes sense, thanks.
>>51709999
.net was always good as a technology, politics/philosophy notwithstanding.
>>51710036
Well, I suppose you could also have an abstract class without any pure virtuals if you delete the default constructor. But yeah.
>>51710019
MinGW is not the compiler. MinGW uses gcc. MinGW pretty much calls the winapi for you.
>>51709459
wow, this idiot
>>51710047
For developing for windows it's great.
Having everything built into framework is fantastic and saves a lot of needless headache.

New friend here, what first language to learn would you recommend to someone with untreated diagnosed ADD (I lost my health insurance, currently moving to another state hoping Medicaid will help). Hoping to learn enough of this new language to get a job. Unfortunately I learned to type with my front and middle fingers so I'm forcing myself to type properly now, but hopefully within a year I'll have learned something that would help me get a job.
>>51710161
literally retarded
he obviously meant
>your iq is lower than 100, isn't it?
>>51710233
What is wrong with that?
If he doesn't care about it and doesn't even act like he does, why does it matter if he wants to do it the easiest way possible?
I literally know people who got a Computer Science degree and have a full time job as a developer and they cheated their way through school and copy/paste and pretend to work hard during their job.
>>51710233
lots of people do that.
what's the difference between doing that and using a library?
>>51710197
>literally smoking cigars
wow you're living the life man. at this point why don't you just retire and dedicate your life to philanthropy and fucking bitches, and smoking cigars of course
>>51710245
For what? Copy pasting public code isn't illegal.
What is wrong with using the easiest method possible to achieve a needed goal?
If I need a script to parse some files why do I have to manually write it when I just can copy it and modify it to my needs?
>>51710266
NEETs don't understand.
They have severe autism so the only achievement in their pitiful life is knowing they spent weeks doing something the hard way when you could've used a library and asked someone for help and do it in a few hours then relax the rest of the time, or focus on something else.
>>51710273
>Copy pasting public code isn't illegal
Sometimes ;)
Absolutely nothing wrong with copying and pasting code if you understand it.
>>51710287
not everyone is a wage slave who only works on doing trivial shit that has already been solved. you're probably too stupid to even realize how sad you are for bragging about being a mediocre code monkey
>>51710299
Especially if your job isn't being a developer or a computer science enthusiast.
if you just need something "to werk", who the fuck cares?
>>51710299
in fact, I'd say it's practically impossible to do that without understanding it, at least a bit. in all cases, you have to understand the concepts to make something that actually works.
hey guys. i have an awsum idea for a game. i just need a coder to help me make it. i'll even offer u 50% of any profits. any takers? :)
