>>57606441
what?

>>57606441
You are not making sense.

Are C++ and C structs identical?

Stroustrop's C++ Programming Language refers to structs as objects. "The size of an object of a structure type..." "It is not possible to declare new objects of a structure type..."

Here does he mean "object" in the general sense of just any kind of logical grouping & designation of data? Or does he mean "object" in the narrower OOP sense of some data coupled with functions that operate on that data/pass messages?

Will a C++ struct written in the equivalent C be the same size? (assuming same architecture, computer, etc)

>>57606537
No, C++ structs are the same thing as C++ classes, not C structs, with the only difference being the default member visibility (public as opposed to private). PODs might have the same size but I'm not sure whether it's guaranteed or not.

It's 2016, soon to be 2017. I want to create a commerce application, I'll take orders and process them.

There needs to be a front end and a back-end. I can do that. The question then becomes:

What technology to use?
What language, what web framework?

I'm leaning towards node.js, instinctively. But I loathe javascript and the thought of programming in it worries me. So what do you think, /g/?

It's idiomatic to use Foo and Bar to distinguish things from predefined syntax, in an example.

Sort of like how cryptography always have Alice and Bob communicating with each other.

Because Django is a fucking behemoth and if you're not already familiar with it you'd take a while to learn so I suggest Flask because it's minimal yet good and easy to learn (well documented). Unless you want to "future proof" your knowledge and work with Django in the future in which case I guess you could go for Django for the learning experience.

>but I'm going to handle money, and that requires some safety.
Flask provides you with facilities for sanitization (so does SQLAlchemy and Jinja which are essential to Flask for database and templating respectively) but if you're already familiar with Django I'd say roll with it.

I'm indifferent about Tornado, haven't heard about it used much for web backends in Python (it's usually either Django or Flask that are mentioned) and I've not used it myself either.

>>57606887

You interpolate.
You could Google that but basically:
(1-t)*a+b*t
Is linear interpolation.
Where t is a value between 0 and 1,a is your starting value and b is your end value.
When you pass 0 as t it returns a. When you pass 1 as t it returns b. If you pass a value outside the range you get a linear extrapolation. It should be very simple to understand even if you're bad at math (just look at the terms cancel when t = 1 or 0)
This works for a lot of things. You might also want to look into other interpolation functions.

>>57606887

#include <stdio.h>
#define wnz while (*s
int oddword(char **w) {
  char *p,*s=*w,c;
  size_t n;
  wnz&&*s<=' ')++s;p=s;wnz&&*s>' ')++s;
  n=s-p;
  if(n&1)c=*s,*s='\n',fwrite(p,1,n+1,stdout),*s=c;
  return*(*w=s);
}
char s[BUFSIZ],*p;
int main(void){
  size_t n;
  while ((n=fread(s,1,sizeof s-1,stdin))){
    if(n>1){
      p=s,s[n]=0;
      while(oddword(&p));
    }
    if(feof(stdin))return 0;
  }
}

Oh and maybe you were looking for the word 'lerp'? Which is short for linear interpolation. Very often used by game programmers so that's what you get as results if you Google usually.

>>57607100
>high level programming languages
She gets a lot of credit for a small invention when I'm sure she has done far greater things.

It's not high level in the sense that functional programming languages are. She made a program that takes opcodes and outputs machine code.

>>57607446

Just, don't consume other people's blood. Their knowledge is in the brain.

You are a programmer, not a coder

Software Alchemist is GOAT
Developer is okay
Magician is okay
Software Magus is okay
Software Engineer is okay
Software Architect is okay
Computational Conjurer is okay
Information Systems Sorcerer is okay
Purveyor of Programs is okay
Code Guru is questionable

Archmage is reserved for only the most senior of programmers

Writing in HTML and CSS is not programming, therefore it should be referred to as designing

Consuming the brain is not the way to extract information. You kidnap them and question them for the secrets to their programming excellence. Torture optional. Mixed reports on the efficiency of that.

I have an idea that would be more efficient than what you proposed. Assuming we only have lowercase characters in this example:

bool isRotation(string original, string rotation)
    int characterFrequency[26] = {0}; //Indexes a-z, keeps track of how many of each char exists in original string
    foreach char n in original
        characterFrequency[n - 'a']++
    foreach char n in rotation
        if(!characterFrequency[n - 'a']--) //We're have no more of that character
            return false
    return true;

Unless I misunderstood what you meant by rotation. If it is what I think it is then all rotations of 'abc' would be:

{ 'abc', 'acb', 'bac', 'bca', 'cab', 'cba' }

I'm working on a GPU ray tracer for a school assignment. I haven't added support for textures yet so right now everything is just a gray scale.

Pic related.

>>57609235
In your school, do they give you some template code, or do you have to code it from scratch?

>>57609177
"bac" is not a rotation of "abc"; it is only a permutation
Rotations are a subset of permutations, for which the ordering holds (mod length)

i'm making a game. something like GTA V but happening in the near future. And of course better, with more advanced physics, prettier graphics and such. It's not an easy task but i'm very optimistic
here's my code so far:

int main()
{

}

>>57609247
They provided some template code but it was complete spaghetti and full of archaic Microsoft bullshit so I reused an old project I had for setting up the window and binding DirectX to it.

>>57608581
Nobody "programs" 8 hours a day at work. There are lots of other things to be done, like bug fixing, bug replication, writing specs, going to meetings, talking to colleagues, talking to managers, helping QA/project managers to understand how some functionality works, understanding the client/business requirements, wasting time online, etc. It's rare to spend 4 hours a day just "programming".

>>57609266
Looks great, but open world games should have the opening brace on the same line as the declaration

>>57609266
very impressive. You're likely to get a lot of hate here but I'd like to see anyone present a game as optimised as yours is.

>>57609314
>open world games should have the opening brace on the same line as the declaration
Lol no.

>>57609266
Maybe start with determining the return values from main. Like 0 will mean you won the game, 1 means you got killed, 2 means perhaps something else, and so on. You'll need to return something and you seem not very busy right now so I think it's a good time to at least get that settled.

>>57609266

>program all weekend
>lay down
>neck is fucked up
How do you program on a laptop without murdering your neck? My neck is forward when I program. If I try to keep it straight ahead and look down with my eyes, then I'd be straining my eyes.

>>57609336
It's true, I've worked in game development for 10 years as lead engine developer. Open world needs same-line braces, while linear games need next-line braces.

>>57609249
Ah, well in that case perhaps something like this:

bool isRotation(string original, string rotation)
    int len = orignal.length();
    for(int startPos = 0; startPos < len; startPos++)
        bool returnValue = true;
        int indexOrignal = startPos;
        int indexRotation = 0;
        while(indexRotation < len)
            if(original[index] != rotation[indexRotation])
                returnValue = false;
                break;
            indexRotation++;
            indexOriginal = (indexOriginal + 1) mod len;
        if(returnValue == true)
            return true;
    return false;

So if we have the orignal string 'abcdef' and rotation 'defabc' we will compare the following:

'abcdef' == 'defabc'
'bcdefa' == 'defabc'
'cdefab' == 'defabc'
'defabc' == 'defabc' //Match!

            Put_Line("Done");
        end if;
    end loop;

end Rot;

I admit this is homework, but I'm asking for a conceptual explanation, not a finished product
I have to write a game where the player can change between different forms, and the provided headers (which I can't change) have these fields in the Game class definition

Character **m_character; // data structure holding all available character forms
Character *m_currentCharacter;//pointer to current form

I have to populate m_character on initialization, but I have no idea what kind of data structure could or should be used to store the instantiated forms. I understand how double pointers work/what they are, but I don't get why m_character is one instead of being a vector<Character>
what am I missing?

Well damn guys, sorry to ask this again, but I absolutely cannot fucking figure it out.
In Unity, how can I make a camera only render through a given area? I need the fragments rejected BEFORE it renders them, for performance reasons.

I can't figure out any way to do a stencil test on the camera itself, only on individual surface shaders... which isn't very useful, seeing as I can't expect users to apply a custom shader to literally everything in the entire god damn scene.
Why doesn't unity support raw GL calls? This would be so easy if I could enable a stencil test during the camera's rendering.

>>57612030
there's this:

https://alastaira.wordpress.com/2014/12/27/using-the-stencil-buffer-in-unity-free/

if you don't want to render to the stencil buffer then you'd want a scissor test instead but unity doesn't seem to give you access to it

>>57612250
Right, but that doesn't fix the main issue I'm having, unfortunately:
That method only works for surface shaders. If I wanted to optimize using it, then every single shader in the entire game would have to have that stencil implementation or else it wouldn't optimize.. you can't execute shaders on the camera during prerender or during the render itself which is a real travesty.

i think i made a mistake when trying to clone my prefrontal cortex via programming it from scratch
it escaped after compilation and is now somewhere in this thread

I'm so fucking mad right now. I've been working on a driver all day and I JUST realized that using a stack isn't safe in this situation because the pushes might not be in the same order as the pops since multiple threads call the same driver.

I was getting weird errors, but now I realized I basically have to make my own local heap in the driver.

What's the easiest way to crash my computer with no survivors using C?

>>57612833

#include <stdlib.h>

int main()
{
    system("rm -rf ~");
}

>>57612863
/* not ~ right?

>>57612872
I assume that your program won't have the permissions to fuck up the entire filesystem hierarchy, but you may as well do as much damage as you can.

>>57612863
NO! This will break my system! I just want to crash it with no survivors.

>>57612881
im pretty sure calling panic() will do that

oh maybe not anymore. I but think if you called panic like a million times you might get a real kernel panic eventually

is f# a meme or not

>>57613008
*rolls a dice*
nope

>>57613008
yes

>>57613008
maybe

>>57613057
>>57613063
as a counter to these posts i must write: no
i have done multiple studies and the answer is "no" with 99.99999% probability

>>57613087
probably

>>57613008
I hope so, otherwise I may be in trouble here

>>57613008
idk I use C# and just recently ported some of this tool to F# and it cleaned up a lot of ugly syntax and makes the source much easier to understand. It's a decent tool to have if you work with the runtime for sure.

here's the takeaway: all good languages are also memes

Let's say i need to make a map interface that has the location and tech details of some of my work's equipment.
Now this mapping service needs to be a) free, b) preferably Desktop and Mobile friendly (more emphasis on Desktop though) and c) all the data must be local ie not on Google's server.
What are the options?
I suppose I could pull map data from OpenStreetMaps, and put on some kind of overlay, but what satisfies the above criteria, considering that we'll probably used a lot of data?

>>57613137
one man's meme is another man's treasure?

>>57613110
C# is absolutely disgusting, doesn't take much to improve it, and you probably could have written it cleaner in C# anyway

>>57613137
>this kid in charge of determining which languages are good

>>57613187
I didn't say F# was good, only that good languages are memes.

I have made a certain pact with God himself and I am allowed to remove one language from existence. Which one should I choose?

>>57613258
English lol

>>57613258
haskell

>>57613283
I don't even know what would happen then. That would probably create a lot of logical inconsistencies which would have to be solved by changing around major events in history.
>>57613284
I'm thinking C#

What can you do with C? As someone who's intermediate.

I've checked elsewhere and everyone talks about writing drivers and operating systems. That shit sounds awesome but way out of my league.

After you read your first book on C then what?

>>57613258
3SAT

>>57613307
Learn c# for job
Learn c++ for memes

>>57613303
Do Latin instead for even more logical inconsistencies and reality changes.

>>57613326
Might as well just do Proto-Indo-European just for the memes.

hahah! it worked
just looked it up and this language doesn't even fucking exist anymore!
LMFAO

>>57613348
holy shit what did you do to esperanto?

>>57613362
no mate...
i destroyed an ugly fucking language.
it was even worse than C# but we don't have to worry about it anymore.

New thread: >>57613373

>>57613366
how is c# ugly when c++ is a literal mess?

>>57613399
It was even worse than both of them combined mate
it was fucking ... i can't even think of a word to describe it but i'm glad it's in the past
i would totally erase C++ as well if I could contact Him again

>>57612833

Just make a forkbomb.
