f-fuck you guys

functional programming is actually good though

>>9550047
glad you said this, OP. I read a book on haskell a few years ago and decided it was retarded.

newState = someFunction(state)

there. do this and it makes testing easier because you don't have to mock everything. all the monad functor bullshit is just intellectual masturbation.

> newState = someFunction(state)

Oh my god, did you just use a VARIABLE? BLASPHEMY!!!

>>9550105
There's literally nothing wrong with intellectual masturbation enginigger.
Problem is, CS is pseudointellectual masturbation.

Computation is a dynamical system, and changes of state are at the cornerstone of every algorithm and other mechanism. Functional and object-oriented programming are two different ways of hiding this simple fact behind empty abstractions, when all you need to know about a computer system is how it changes over time and reacts to different scenarios, and you instinctively consider such cases when you want to test the behavior (again a dynamical construct) of the system.

>>9550105
That's literally what the state monad does. Maybe you should have kept reading, apparently you didn't understand it very well.

This doesn't even make any sense; algorithms can't be NP-complete, only the decision problems that they attempt to solve. And RSA is not an attempt to solve the integer factorization problem, and the integer factorization problem is most probably not NP-complete.

That's the whole point of the joke, brainlet. The fact you didn't mention anything else strongly implies you didn't see anything else wrong with what blue said; which is highly troubling but expected of cs majors...

>>9550431
LOL, I'm math major. What was actually wrong with what I said, other than your false attempt at guessing what my major is?

If you're at all fucking literate, you can see the phrase "decision problem" in the following screenshot.

The text in the image is reflective what a non-CS major thinks a qualified CS person would say, but given the numerous objectively incorrect errors in the text, it's clear that the person who made it has zero clue about what he's saying, much like you probably do since you spend your life shitting on random academic subjects on /sci/. At this point, claiming that "uhhh the mistake was the JOKE brainlet" is like saying "yeah haha i was being retarded on PURPOSE troled much?"

>>9550431

Also, you call me clueless for saying that RSA is not an attempt to solve the integer factorization problem.

But how the fuck is RSA an attempt to solve the integer factorization problem (or, more precisely, EFFICIENTLY solve the integer factorization problem)?

It's a cryptosystem designed to explicitly use the difficulty of efficiently solving the integer factorization problem in order to develop a psuedo-trapdoor (psuedo because, again, integer factorization is in BQP).

God, I need to get off this fucking board. All it is is fucking undergrad brainlets calling other undergrad brainlets brainlets because they don't like their choice of major, and then I get angry when some fucking brainlet calls me a brainlet. Even if I were a brainlet, you certainly would have no authority in the matter. God. Fuck this shitty fucking website.

>>9550441
>https://en.wikipedia.org/wiki/FNP_(complexity)
>In computational complexity theory, the complexity class FNP is the function problem extension of the decision problem class NP.
>Many problems in NP, including many NP-complete problems, ask whether a particular object exists, such as a satisfying assignment, a graph coloring, or a clique of a certain size. The FNP versions of these problems ask not only if it exists but what its value is if it does. This means that the FNP version of every NP-complete problem is NP-hard. Bellare and Goldwasser showed in 1994 using some standard assumptions that there exist problems in NP such that their FNP versions are not self-reducible, implying that they are harder than their corresponding decision problem.

>>9550449
Last time I'm responding to this brainlet because I have better things to do in my time.

You randomly link this Wikipedia page (because you're most likely NEET who pretends to understand the Universe because you sit in your basement reading Wikipedia pages) as if it proves that there are complexity classes based on non-decision problems.

But function problems can be trivially made to be decision problems. If you can find any specific answer, obviously you can say whether an answer exists or not.

Maybe the complexity class changes upon transformation, but I never said it didn't. In fact, all I said was that an algorithm that SOLVES a problem can't be NP; the problems THEMSELVES have to be in complexity classes.

Please stop posting anywhere on the Internet, immediately.

Everything the blue guy says is wrong. CS does not learn more math than other stem majors, CS is not a superset of math, that math he cites is all trivial day 1 topics showing how shallow CS math education is, his own knowledge of CS is incorrect by saying RSA is NPC, QC are trianary, thinking the singularity is real, and so on.

And it's not "what a non-CS major thinks a qualified CS person would say" strawman; these are all things I've actually heard cs majors/grads say and I've heard even worse.

>>9550445
>Also, you call me clueless for saying that RSA is not an attempt to solve the integer factorization problem.

The RSA Problem reduces to Integer Factorization but the RSA problem is NOT equivalent to integer factorization.

https://en.wikipedia.org/wiki/RSA_problem
>the RSA problem is at least as easy as factoring, but it might well be easier. Indeed, there is strong evidence pointing to this conclusion: that a method to break the RSA method cannot be converted necessarily into a method for factoring large semiprimes. This is perhaps easiest to see by the sheer overkill of the factoring approach: the RSA problem asks us to decrypt one arbitrary ciphertext, whereas the factoring method reveals the private key: thus decrypting all arbitrary ciphertexts, and it also allows one to perform arbitrary RSA private-key encryptions. Along these same lines, finding the decryption exponent d indeed is computationally equivalent to factoring N, even though the RSA problem does not ask for d.

>>9550461
Most CS professors and books use NP and FNP interchangeably. Especially in the context of approximation algorithms. It looks like you're the neet that learns CS by only reading Wikipedia articles...

>>9550082
I always find it funny that sci wants people to think they're the ones that don't care about cs (the sci guy is supposed to be the uncaring one) but instead its the opposite. Just look at this thread where the uncaring /sci/ went out of their way to talk about cs (again) all while acting like they somehow know better (they don't). Its a funny obsession from a group of people that "don't care".

The fact someone sperged out to the point they made this image and the tons of other images that keeps getting reposted by the drones shows how butthurt /sci/ gets over cs. If you really believed you where better then why do you need to constantly attempt to reaffirm to everyone and yourself that you are better? That shows that you're actually insecure and feel inferior. Its a rightful insecurity, you are inferior.

Success breeds jealousy after all. Hell this post alone will get massive butthurt from the unemployed math fags and the homo engees. I can already smell the false memes like "you don't take enough math or physics" when the truth is far different. I guess you have to lie to yourself to try and feel better when you're clearly not. Keep seething but no matter how much you try and lie to yourself you will always be inferior :^)

>>9550469
This.

The value of a degree is pretty heavily weighed on the salary it can get you. CS might be easier than other degrees but when you're getting paid more it's pretty retarded to hate the CS grads.

Math grads are pretty good coders, but they have to put in effort to learn more outside of their course to be really employable. Not so much for CS.

I agree that OOP is shit in 99% of cases, but as a professional game developer, I can say with utmost certainty that OOP fits game-design perfectly. It is the only place in programming in which the OOP allegories like dog.bark() will ever exist. Additionally, it's used fucking constantly in game development. If you think otherwise, you're just retarded.

This. Math majors as a group somehow manage to write less-optimized and less-readable code than engineers. I was reading a Math major's code a week ago, and this man was slapping together no-indents PHP code that had glaring security holes and had reinvented selection sort.
The only field that has competency in programming outside of CS/CE is physics, since their field is based on logical conclusions and not opinion-centric axioms.

>>9550739
>tfw you realize that """"coding"""" is for plebs

>>9550739
>this strawman again

Math majors and physics majors don't take coding classes. If they don't care enough to spend time learning how to program, their code is going to stick. This does not mean they can't be good nor CS majors are super special elites for mastering the mysterious art of fizzbuzz. A math major that spent the time to get good at programming is always better than a cs major.

That said, CS majors as a group somehow manage to write horrible code when they don't have an excuse to explain it away.

i read teh thread but y'all are motherfuckers so im ignoring you

even if you ignore 99% of what functional programming has to offer, closures are just way too fucking useful. learning enough FP to get when you'd use them and how is a huge improvement for most programmers.

I think the problem is literally anyone can learn computer science with practice and there just happens to be a demand for it right now. It makes your options feel like contributing to a legitimate field or being a sellout, I'm saying this as someone being forced to choose between doing what I love with no job options or going into a field that relies entirely on programming.

>>9551658
Not more than other majors, frankly. Most students in all categories of engineering got in just because it pays good and they got a good score on their high school diploma. They chose whatever they thought was cool enough for them but are lukewarm as fuck about it. Very few CS majors even learn another text editor than whatever they were taught during freshman (i.e. Emacsimumgarbage). Very few EE majors own a soldering iron or Raspi at home to tinker with. Very few ME majors use MATLAB for anything beside homework. Very few science students in general download and read scientific papers just to keep in touch with the research past the "just buy the Times magazine and read the science column" level (it's already a fucking miracle when they don't use Khek Academy and the only reason it works better than class is because they don't pay attention in class). That's just the way it is, and just because your major involves more math doesn't mean students are smarter (at best they're more used to stupid shit they don't care about and will forget the day after graduation).

>>9551807
You've seen nothing yet. I've seen such things as "Dairy product BSc." Also, telecom engineers are notoriously incompetent fuckers. In my school, the only things they're famous for is being lazy faggots, partying as hard as possible to have an excuse to skip class the next day, organizing buffets during company events to feel like they worked hard and deserved it and sucking the administrator's balls to appear more relevant. The only time I've ever seen someone defend them is when an EE student got autistically sour grape over CS (btw, did you know that in reality, EE majors are not capable of programming as good as CS majors, who are already pretty mediocre on average, and that's why they hate CS?).

I learned how to solve 3x3 systems of linear equations using Gaussian elimination in community college and thought/think that it is really easy!!!!!

Why is /sci/ so anti intellectual all the time? I don't understand the point of limiting yourself to one and only one field of study. Why not be well versed in everything? Since when is computer science the enemy of math and physics?

>>9551672
it's basically about constructing your functions so that there's a very, very predictable relationship between input and output. your function takes a single input data point and returns a single input data point. every function does one thing and one thing only. you have no variables floating around that can vary at any point in time and might affect function output.

it's easier to define it by comparison as well. in OOP, you can run into a situation where you have an object with several methods and several variables, and the behavior of each of those methods might vary according to what variables are defined and what their values are. in FP, instead of that, you would define a single function that performs a certain operation and then you'd construct other functions that take that function and give it different parameters.

consider the difference between:

class Type:
def __init__(self,x1,x2):
self.x1=x1
self.x2=x2
def m1(self,x3):
return(x1+x2+x3)

vs

def addx1(y):
return(y+x1)

def addx2(y):
return(y+x2)

def add3(y):
return(addx1(addx2(y)))


this contrived example is convoluted and at first glance it might seem like the OOP approach is way easier to write and maintain. however, there are certain use cases (parallel execution is the best example) where it's more efficient to do the FP approach

Why? Try and answer this without resorting to /sci/ memes. You can't, because memes are the only thing you know about cs.

CS is very important in the modern age. It may be one of the youngest fields but it has heavily contributed to modern society. The field is still growing, to claim it deserves the most ridicule only shows your ignorance.

auto addx2 = [x2](auto y) constexpr { return x2 + y };
auto addx3 = [](auto y) constexpr { return addx1(addx2(y)); };

And realistically you would use function that returns a function if you're creating similar functions differing by a capture.

constexpr auto capture_n_add = [](auto x) { return [=](auto y) {return x+y;}; };
constexpr auto addx1 = capture_n_add(x1);
constexpr auto addx2 = capture_n_add(x2);

Oh look, its this meme again. Isn't it funny that every single of one your ""arguments"" against CS are basically memes? Its almost like none of you have anything substantive to say against it.

Also math is far easier then physics. Math fags don't have to take physics so they never realize that. Math fags in the end are brainlets who struggle taking basic physics classes.

You're somewhat right, liberal colleges and some unis make a mockery out of CS. Even then those are few and far between while many schools give great CS degrees that are anything but watered down. CS isn't too well defined so of course there would be differences in programs but in recent years they've attempted to fix these problems by creating new classifications like information systems. You only focus on a minority while ignoring the whole. I get that's the way you justify your hate to feel better about your major yet when compared to an actually decent cs degree your argument falls flat. Of course you're not gonna care for that because your childish insecurities prevent you from seeing reality. Keep being butthurt.

It's literally perfect for them. The main issue is over-use of OOP for very small things, especially when it doesn't fit very well, basically obfuscating code when it doesn't need to be. OOP is necessary for much of serious development, and it excels at particular project types (the ones you mentioned, for example). Only peasant programmers bitch and moan about it, as they have no deeper knowledge on the topic or engineering knowledge/experience.

Why do you assume it's a variable? One can't even say that for sure in:

newState = someFunction(oldState)
newState = someFunction(newState)

Naming values != making them variables.

>>9553000
Bullshit, it may be used to separate large parts of games a little, and for some reason indie gamedev are obsessed with it, but in AAA games OOP is used very seldom. Any good AAA studio will fire you inordinately if you use interfaces, inheritance, virtual methods or any other retarded OOP constructs. The only thing they do sometimes use are pure data containing objects, without all the encapsulation shit like member properties, getter, setters or whatever people can think of to make code slower. OOP is designed to separate the programmer from what's actualy happening, while for AAA games they need to know exactly what is going on, even to the extent that they will edit the assembly to squire out any performance they can't using C++.

>>9554989
Any serious software uses a performance-optimized subset of C++, which is "C with classes and templates". Virtual function calls are rarely a performance bottleneck unless they're used on leaf node computations, and there is essentially never any use case for inline assembly in C++ anymore as a general use case scenario - the exception is in heavy computation leaf nodes, and this inlined assembly is ALWAYS heavily wrapped with OOP constructs to avoid the introduction of regressions through programmer fuckups.

The fact that you separate "interfaces, inheritance, and virtual methods" into their own topics to avoid when they're all literally the same thing - virtual dispatching - demonstrates how you have no idea what you're talking about, as well as your weird wording of "they will edit the assembly" as opposed to "inline assembly"

It's good that you're using a performance mindset here but you're prematurely optimizing and making false optimization decisions. The prime performance bottleneck is basically always algorithmic complexity, not virtual dispatching

>>9554989
>t. CS major who thinks C++ is the same as Java and that C is low level

>>9554996
>Templates
That's something they avoid for entirely different reasons, a large codebase like a game will use templates extremely rarely because it increases compile times a shitload. Game studios use text transformations to create 'templates' pre-compile time.

Never gonna make it.

Enjoy those runtime branching costs, I'll stick with compiletime

>>9555057
Please contact @insomniacgames and let them know about this, their head programmers seem to not know about any of this, I'm sure they will appreciate you increasing their runtime performance and lowering their compile times past what they could manage.

why is this place so OBSESSED with CS majors? is it because they're the only STEM major that gets paid immediately after undergrad?

CS PhD student reporting. My story is like this:

That's my perspective of CS studies in Poland, in one of the main universities. I have a very hard time now, because nobody required me to actually understand any mathematical proofs before. I like programming, so I liked the SE classes, but something's not right with this.

>>9555366
Don't worry, even on PhD student level, the math needed in CS is pretty babby-tier. Take introductory courses on calculus, probability, linear algebra and statistics and you'll be OK.

Not the anon you were talking to, but I think he refers to the dirac delta distribution (sometimes misnamed as a function), as well as other distribution-like behavior in functional problems that were used by physicists and engineers before the development of functional calculus.

>>9555366
>>9555373
Eh, well it depends on what you want to do. You need some formal math for TCS (e.g. algorithms, complexity theory, language theory), but for the rest some basic engineering math is sufficient.
