Thank you for using an anime image.
Why do people still use OOP?
Where is VPS guy?
>>55305159
Because it's easy.
>>55305185
no, it's not
its an abstraction layer, it's no worse than a framework and just makes your program even more complicated than it should be, if you find defining 500 methods just to set a variable to 1 "easy" then you're fucked lad
>>55305159
>Why do people still use OOP?
It works decently for a lot of problems. Obviously, it's flawed, but it helps get work done.
>>55305230
It's a layer of abstraction on top of a hundred layers of obfuscation.
Abstract doesn't mean more complex. It just means different.
>>55305159
Same reason they use functions.
Same reason they don't write code in assembly, or a hex editor, or a magnetized needle and a steady hand.

How do I get good at C? I'm looking to get into embedded systems, so I feel like I should somewhat "master" the language. However I feel that solving your standard programming exercises in C is more tedious than it is educational.

Right a datastructure in C.
Then beat it's performance in assembler.
The best way to master anything is to work out how it works underneath.

Well, I finally got my menus finished after a trip to the bathroom and some Spaghetti O's
I also started on the fake conversation panel. It changes every time I click my waifu.
Gonna need to figure out a good randomization technique and lots of lewd shit she can say to me.
Also gonna have to set some thresholds for an image changer, so I can turn her into a hentai game... But I'm gonna have to pick some decent images. I'm not sure I currently have what I'll need.
Also, need to decide how I'm gonna handle the middle panel. I kinda wanna AJAX load some pages into it when I click links from the navigation menu.
Also considering the hentai game being /activated/ after a certain number of actions, and then it overlays onto the page. Now sure what I wanna do with the game yet, though, exactly. I'll need to sleep on it probably...
I'm also gonna have to really make a choice regarding how I'm gonna use that middle panel... Maybe that can be the game? IDK.
>>55305751
4 hours for Spaghetti O's? Man, that must suck.
anyone have any experience with free image. I cant tell if its converting things to bgra by default or if thats just how the image is formated.
>>55305788
no, dude, I worked on it some more after I left, then I took a crap.
I also have OCD, so when I'm done on the toilet, I'll wash up for like 40 minutes.
THEN I got back to working on this.
So, say around 30 mins before bathroom ,1½ in bathroom, then around 45 minutes of eating and stuff, and another half hour coding some more. Also, chatted with a friend briefly and goofed around on a few DNews YouTube vids

>Why do people still use OOP?
You don't have to go over the top to use it like java forces you, it's very helpful when it would benefit the client greatly to have a simplified interface that is class specific.
Consider the pthreads api for C, you declare structs for the pthread itself, mutexes, semaphores, etc. The information for the structs is hidden using some clever compilation tricks so that the client doesn't access the data directly. Classes in OOP languages can instead encapsulate that data.
To start, you first use an interface to initalize the values, usually called pthread_[struct type]_init(bunch of variables or other structs) and then when you're finished using them you have to call pthread_[struct type]_destroy(struct). It's simple but constructors/destructors from OOP are great at managing that.
In addition, calling these seemingly independent functions from pthreads.h like pthread_join, pthread_create, pthread_cancel, etc. are much more simpler to utilize when they are called on the pthread_t you are manipulating rather than passing the pthread_t around.
And resource management when working with pointers is made so much nicer using OOP constructs.
That's just my opinion on why OOP is useful even if there's ugly shit like abstractMethodExceptionCatcherFactoryInterface and stuff.
>>55306052
C pointers aren't the C++ way to do things.

a c++ program that connects to websockets. I need help. I am using this library (https://github.com/zaphoyd/websocketpp) to connect to the websockets, but it only works with unencrypted websockets (ws://) instead of encrypted websockets (wss://). I am basing my project off of this example (https://github.com/zaphoyd/websocketpp/blob/master/examples/utility_client/utility_client.cpp), and cannot get the tls_handler to fucking work. I've followed what this fag said here (https://groups.google.com/forum/#!topic/websocketpp/SimAUzwZUVM), and it still doesnt work. After I did what he said, it basically gave me a generic 'could not connect' for both the encrypted and nonencrypted connection. If anyone knows what I'm talking about, please help before I kms.

Can someone explain this behavior in Python 3.5? I know C++, so I know how pass by value, pass by reference, and pointers all work. But I am confused about what's going on here because Python is new to me:class ABC:
listOne = list()
listTwo = list()
def __init__(self):
self.listTwo = list()
a = ABC()
b = ABC()
a.listOne.append("One")
a.listTwo.append("One")
b.listOne.append("Two")
b.listTwo.append("Two")
print("a.listOne: ", a.listOne)
print("a.listTwo: ", a.listTwo)
print("b.listOne: ", b.listOne)
print("b.listTwo: ", b.listTwo)
Output:a.listOne: ['One', 'Two']
a.listTwo: ['One']
b.listOne: ['One', 'Two']
b.listTwo: ['Two']

I need this because I want to paste a file into multiple selected folders. holy shit why is simple shit so difficult.
>>55305159
Encapsulation, Inheritance, and Polymorphism
>>55308113
listOne is a class level variable, therefore it's shared among all the instances of that class
listTwo is an instance level variable since you're setting it in the constructor, so the contents are specific to that instance
>>55308167
>Encapsulation
Fundamentally flawed
>Inheritance
Shit
>Polymorphism
Not exclusive to OOP
>>55305159
What programs have you made without OOP?
Python never ceases to amaze me.
I just found out that "foo" in s is faster than s.startswith("foo").
What the fuck.
>>55308113
Basically if you define variables outside of the methods, they're actually static members, not member variables.
As if:struct A {
static std::list<std::string> one{};
static std::list<std::string> two{};
std::list<std::string> two{}; // let's pretend this is allowed
A(): two{} {
}
};
Is it possible to hide the code of a python script?
I got memed my a company that is using python : they kept promising me I'll have a bonus at the end of my internship if I get beyond the original objective, which I did, and got nothing but the bare legal minimum.
I continued the project on my own and eventually managed to get something I can sell them for a fair price. Since they'll ask for a proof, I want to give them a sort of proprietary blob to prove my point and give them the source once I get my bucks.
I know we can do so in matlab but I never heard of such thing in Python.
Is rewriting the stuff in C, compiling it and calling the program in a python script my only solution? Feels overengineered.
>>55308338
(To expand upon this, both are accessed with the dot but the latter is simply being overriden).
>>55308378
IL or object code?
>>55308295
not really once the string starts getting bigger
not all that surprising on smaller strings either as operators are generally faster that function calls
>>55308378
you can compile python to an executable, not sure how hidden the code is though
>>55308444
object code I guess. https://wiki.python.org/moin/Asking%20for%20Help/How%20do%20you%20protect%20Python%20source%20code%3F says I should gibberish my variable and function names before I compile it into some .pyc and it should be enough but I think I'd better ask for other's opinion.

Another question: How do I type hint for lists of objects? Like if I had a list containing ABC objects, how would I type hint to them? I'm using PyCharm.
In this case, the type hinting works for the single object, but not a list containing that object:def tester(ABCObject, ABCList):
'''
:param ABCObject: Takes a single instance of an ABC
:type ABCObject: ABC
:param ABCList: Takes a list containing ABC
:type ABCList: list
'''
>>55308718
Not your personal army
>>55308759
Nv, figured it out. It's''':type ABCList: list[abc]'''
>>55308536
it would be hilariously easily to reverse engineer, it can be decompiled to something pretty close to the source.
>>55308378
understand that anything can be reverse engineered, it just depends on how much effort one is willing to put in.
with that said, how worried are you that they will try to cuck you? the case might be that simply obfuscating the shit out of it might be enough. or you might have to rewrite it in C and employ a bunch of anti-debugging techniques.

this is not only about me, you will benefit from this too, but OK, whatever floats your boat.
For fun, I want to create a python program that will collect all the data while I play Overwatch.
Preferably, I'd like the data to be the amount of keystrokes entered, internet speed, characters chosen, specials activated, life of player, etc.
Are there any anons that can provide input on how to get started with this in Python? I'm not even sure if I'd be able to do this, as surely Blizzard has some sort of authentication feature that would stop my python program from doing this.
Not sure if this is over my head, but I'm just curious as to how one would do this.
>>55308834
>Not sure if this is over my head
it almost certainly is
you either need to cause the game to load a .dll you create, either at runtime or by creating a remote thread in the process which calls LoadLibrary
or you can read the data out of the game from your process with ReadProcessMemory
either way you need to reverse at least a little of the game to figure out where the data is located
which means you also need to know at least some x86 asm
>>55308827
>this is not only about me, you will benefit from this too, but OK, whatever floats your boat.
I don't benefit because I don't go to dumb shit threads like speccy or desktop so I don't see any of that shit anyway. Likewise, their existence works as containment because it keeps speccy retards from shitting up my serious discussions.
If you want to post somewhere where users actively prevent certain discussions, reddit or voat are prime candidates for you to go to.

Yeah, I know, but I believe they'll realize that it would be cheaper to help me repay a part of my student loan than paying the man-hours to reverse engineer instead of working on their own tasks. (or he'll just cuck another intern into doing it for him)
>with that said, how worried are you that they will try to cuck you? [...] you might have to rewrite it in C and employ a bunch of anti-debugging techniques.
As much as he can I guess. Since I don't know the extend of decompyle I guess C is the safest solution.

the Polymorphism in OOP languages is dogshit compared to haskell

Literally why? If you need polymorphism, that's a failing of your program architecture and you should rethink it.
I think I may start using Rake for building C and C++ programs... or at least experimenting with it to see if it is useful for, say, cross platform development.

you probably shouldn't use inheritance at all
composition is superior
I'm about to write a simple program in C that requires random data that I'm going to store into an array. Rather than do rand() i'm thinking why not just not initialize the array and use the random junk. I don't need any guarantees or anything. viable?
>>55310387
>viable?
yeah
keep in mind that it will work better in release mode because compilers will often do things like automatically initialize memory to 0 if you pass debug flags
>>55310382
Why not both?
>>55310356
It doesn't make any sense to duplicate code in that manner. (And templates duplicate a shit ton of code).
It's more reasonable to compose the types you need.

So I have a big project for school and I'm not really a good programmer. Where do I start making my design? I need to make some mockups and some UML diagrams.

>>55310654
It's parametric polymorphism done right.f :: (a -> b) -> (b -> c) -> (a -> c)
When we disallow non-total functions, there is only one implementation of this function. You don't even need to write tests. There's only one thing it could do.
But in languages with shitty implementations of polymorphism, like C++ and Java, it could do literally anything. It's even worse in something like Python, where you don't even have the type signature.
have you read code complete? how does one read a book like that? i'm used to read math books because that's what i study, but that book has no exercises, there's no obvious way to practice. if i read it, i'm going to forget most of it in half a year. sicp is different, it has a bunch of difficult exercises

how so? did you think everything there was obvious, you didn't appreciate the content or something else?
have you read similar books? any recommendations? i think i'm an okay programmer, but i don't know what the best practices for big projects are
is SICP a meme book?
>>55311576
That's the normal way to create new objects, either using the new operator and/or calling a contructor.
The objects are destroyed automatically by the GC.
>inb4 that good joke about python not having a GC.
>>55311576
that's the standard way to do that. what do you need? why do you want to destroy objects? i don't think you're at a point where you're going to need to manage memory yourself

almost all of it is common sense
it's sort of like a text book in my opinion, where the authors goal is sometimes only to take up as many pages as possible
you can easily sit down and read 80 pages and feel like the author hasn't yet actually said anything
another similarly highly praised book that I've read is The Pragmatic Programmer
it's better in my opinion; there are some gems in there that you will take with you
so I can at least see why it's highly recommended
>>55311460

Will I learn to actually be a good programmer to build a real application from SICP?
>>55311719
thanks mate, that did it
>>55311675
where are you learning from? you need to use a very basic data structure called a list here. do something like "list = []; list.append(object1); list.append(object2); list.append(object3); ..." where objectk is the kth object you want there. all your stuff will be in list and you can access them by index: list[0] == object1, list[1] == object2 and so on. although i don't usually use indexes when i write python
what's the code tag here?
>>55311797
I actually have all my objects in a list, I think I'm doing it wrong, it works, but it looks uglyobj1 = obj(stuff)
obj2 = obj(stuff)
obj3 = obj(otherStuff)
obj4 = obj(otherStuff)
list = [obj1, obg2, obj3, obj4]
>>55311797
i'm not sure what you need, but don't do obj1, obj2, etc. do objects = [obj(stuff), obj(stuff), obj(otherStuff), obj(otherStuff)] and access them by index: objects[0], objects[1], etc
what's the code tag, friend? how do i put stuff in that white square?

consider splitting it into several files. take the first 75 lines and put them in first\ code.cpp, the second 75 lines and put them in second\ code.cpp and so on, and then do
#include <"first\ code.cpp">
#include <"second\ code.cpp">
in a file called all_code.cpp

Ignoring all the stupid shit, you're calling compCast and useCast functions in main and not doing anything with them then you're passing nonexisting variables into winner. Your winner function has does nothing if gibberish gets passed in so it's printing nothing.
>>55312449
This is probably a troll but I'll bite. I can't program in python but I can already see a couple mistakes.
>Name your variables correctly, it's a good habit to get into.
>You don't need to set number = "rock" or anything like that in compCast()
>I bet you could use .toLower() or whatever the python way is, so you just do choice.toLower() == "rock"
>You can make a two dimensional array of integers to represent wins: 0 = tie, 1 = player 1 wins, 2 = player 2 wins
>Also, try to give real names to your functions. compCast doesn't mean anything.

Are there any statisticians on /dpt/?
For my research I'm writing a program that needs to be able to determine the magnitude of the effects of n input variables, which will either be classified as high or low (they're literally just bits, so 1's or 0's), with the output of some scoring function. The scoring function will assign a single scalar value to the sequence of 1's and 0's. Now the issue is, how do I determine the effects of the individual bits without taking into account all possible permutations of the input variables?
In other words instead of testing 000, 001, 010, 011, 100, 101, 110, 111, I might only have data for some subset of them, e.g. 001, 101, 111. So with incomplete data, how can I get an estimate of the effects of each bit on the output of the scoring function?
Unfortunately this is part of a much larger project and stats is not my strong suit. I was considering using a factorial DOE setup, but I don't think that would work because I can't possibly have enough replicates for every permutation.

how the fuck are all these big youtubers getting hacked? it's like the hackers can get into any account. boogie said they stole his phone number and got into his account through that somehow. is there like some exploit that lets you receive other people's text messages or something and then some website does the password reset through that?

>>55313590
it's not really a stupid question though, it's hardly common knowledge (if it is, then youtube/twitter/instagram or whichever site has been compromised really ought to fix it), we need to get to the bottom of this and maybe some people here are infosec guys that could come up with some ideas
given two real valued functions of real variable, how would you check they're equal if you don't have the source code? i was just thinking people don't usually have to do this with computers. checking whether two functions are equal (value-wise) is common in mathematics, but not in programmingIn [1]: f = lambda x: x
In [2]: g = lambda x: x
In [3]: f == g
Out[3]: False
how slow would it be to check all 2^64 values (i don't remember how many represent real numbers) for floating point numbers? makes u think huh
static unsigned sql_insert(const db::song &s)
{
char uri[s.uri().length() + 1];
char title[s.title().length() + 1];
char artist[s.artist().length() + 1];
// Not copying them into a char array causes ASAN to complain about use-after-free errors, not sure why though, as the array returned by std::string::c_str() is valid until the string object is modified.
strcpy(uri, s.uri().c_str());
strcpy(title, s.title().c_str());
strcpy(artist, s.artist().c_str());
sqlite3_bind_text(stmt_insert, 1, uri, -1, SQLITE_STATIC);
sqlite3_bind_text(stmt_insert, 2, title, -1, SQLITE_STATIC);
sqlite3_bind_text(stmt_insert, 3, artist, -1, SQLITE_STATIC);
sqlite3_bind_double(stmt_insert, 4, s.base_prec());
sqlite3_bind_int64(stmt_insert, 5, s.last_played());
sqlite3_bind_int64(stmt_insert, 6, s.times_played());
sqlite3_bind_int64(stmt_insert, 7, s.times_skipped());

GCC supports them regardless, and thanks for reminding me of that, I would've left them in if you hadn't.
>>55313669
Also, what I say problem, I mean the comment. As in why do I need to copy it into a char array so ASAN doesn't complain?
Is it a problem with ASAN or is it a problem with me?
The code I posted compiles and works as expected, but I don't like it.

How come the cgi script downloads every time I press submit?
