I'm trying to make a Pong game in Java using Model-View-Controller design pattern. I have a fully functional Menu with textfields for player names, a spinner for ball speed and a button to start a new PongGame window. I also have a Model where all neccessary variables will be stored.

My problem is this:
I need to use the same instance of Model in the PongGame window to preserve the settings from Menu. How do I launch a second JavaFX window while being able to access Menu's instance of Model?

Is it possible to send either the whole Menu object containing everything or the Model object containing the variables I need to access?

Any ideas?

Alright /dpt/
I need some help

How can I do the following in Python:
>Open a file containing a list of words
>some of the words if reversed are also words on the list
eg: rotator and rotator or redrawer and rewarder
>how do I check which of the words in the file can be reversed to create another word in the file?

I tried making 2 sets and checking using reversed() and [::-1] but no luck at all...

Does anyone use Pascal nowadays?

>>57453717
for each word a in file
for each word b in file
a == reverse b

>>57453717
dictionary map every word to both the word and its reverse and see if you get any collisions

>>57453747
O(n^2) ;)

>>57453717

in Haskell this is just

import Data.List (nubBy)
main = (readFile filename) >>= (print . nubBy test . words)
    where test a b = (a == b) || (reverse a == b)

I fucking swear if I ever meet people responsible for creating git I will punch them in the face.

I have a uni project and starting this year we are required to use git instead of svn, and so far git seems to be worse in every imaginable way possible.

git is strange yes, but svn is prehistoric. Learn git, after that you'll never go back.

That's just so wasteful

Not sure if this is the best place to ask this but here goes nothing.

I've been reworking some GLSL shader stuff lately, when suddenly I realized something. Almost every time you read a tutorial on how to use shaders in OpenGL they first write a shader class:

class Shader {
    ...
    bool load(const std::string &name);
    ...
    void setUniform1i(const std::string &name, const int i);
    ... and so on ...
};

So then they can have multiple shaders going around at the same time, like this:

Shader foo, bar;

foo.load("whatever.shader");
bar.load("somethingelse.shader");

foo.bind();
foo.setUniform1i("crap", 1234);

But why?

In OpenGL, only one shader can be active at any given time. You must glUseProgram(...) a shader before it can be used. You can't even set uniforms and attribute streams without binding a shader. Why use a class for containing a shader and wrapping the glUniform*() calls in member functions, when you can't even use/call them if the shader hasn't been bound?! I know there are bindless shader extensions that allow you to change uniforms without binding a shader, but those aren't very widespread yet.

So *what* purpose does a shader class serve? What do they do that I can't do by just keeping a few GLuint variables around that contain program IDs, then binding them with glUseProgram() and setting uniforms and streams manually (or through VAOs)? OpenGL is not OOP, the shader program is part of the global state, so an OOP shader class approach does not work with it very well.

A global shader manager that prevents the same shader program from being loaded multiple times and takes care of the cleanup I can understand. But not classes for individual shaders.

Have I misunderstood something?

>>57461558
Convenience.

>>57461590
I don't see much convenience in having to lug around references/pointers to shader classes when all I really need is one unsigned integer that identifies the shader program I want to use next.

>>57461683
Good for you then.

I recently got a job offer as a python programmer. I am to write modules for odoo erp. I've got a small assignment to do with odoo and I hated it.

>>57461683
>>57461558
I don't know much about opengl/graphics in general. But I know that games use multiple different shaders depending on the scenario.

Best example I know is that Saints Row 2 on the PC has inside and outside shaders. Things lighten up if the game detects you're inside. And also that bullshit brown overlay that they use to make it realistic but makes it look like shit

>>57461558
People feel the need to use OOP everywhere.
>What do they do that I can't do by just keeping a few GLuint variables around that contain program IDs, then binding them with glUseProgram() and setting uniforms and streams manually (or through VAOs)?
Nothing, except perhaps convenience. And also API independence (so you can swap OpenGL for Direct3D for example).

Every time someone tells me that C is hard or complicated, I am convinced that they have either been programming for less than a year, or that they are unintelligent.

>>57461929
People tend to mistake simplicity for complexity.

>>57461823
>games use multiple different shaders depending on the scenario
You can have 1000 shaders loaded if you want, but only one of them can be actually bound at any given moment. A shader program is made up from multiple individual shaders (vertex/fragment/geometry/etc.) but it's still just "one" program, like you link multiple object files to make an executable.

And only the active shader can have its attributes changed. If you have shaders "foo" and "bar", you can't say "bar.setUniform3f(...)" if the shader "bar" is not bound at the moment. If you do, nothing happens. That's exactly my point: why wrap them in classes when the member functions can do nothing if the shader is not bound? It's pointless abstraction.

>>57461882
>API independence
Not what I'm doing. All my code is OpenGL. Vulkan maybe in the future, but I'm not maintaining multiple renderer backends. Direct3D? Screw that proprietary shit.

>>57461988
>why wrap them in classes when the member functions can do nothing if the shader is not bound
They can, they just have to do glGet to get current program, glUseProgram to set the selected program, glUniform and then glProgram again to restore.

How long does it take to normally learn .net?

>>57462038
.NET is a massive animal, and you really just keep learning it.

That goes for any programming language, really. You've got to define what your target competency level is.

That being said, you can learn C#/.NET enough to perform most basic tasks in a few months, but it's just a massive toolbox and the tools you use on a day-to-day basic will be different than anyone else.

>.NET is a massive animal
does .NET implement leggable?

>>57462008
Which leads to a horrible number of unnecessary state changes. Shader changes are the second-heaviest changes that exist (render targets are the heaviest).

Yeah, I think I've done my decision: no OOP in my shader system.

char *sChar(size_t s) {
  char *str = (char *)malloc(s);
  memset(str, 'x', sizeof(s) -1);
  return str;
}

But in all seriousness, it's not like those questions will be the focus of what you are doing during an interview.

A good thing to fall back on is to answer "undefined behavior or implementation-defined" for something they ask that looks non-nonsensical but apparently will work.

How did you do?

When I took it, their web based test tracked everything you did with webcam activation and what I suspected was javascript that would track you via taking screenshots of your screen so you don't cheat. You can't have programming references either, IIRC. A lot of questions asking you to implement simple stuff but then got progressively harder and then some random math and reasoning questions.

Was stressful and sure enough, didn't get past that initial web test. IMO, I wouldn't work at Amazon after hearing all the stories of how Amazon treats their employees.

The professor did introduce svn. Actually since he goes full command-line-only, git would have probably been the better choice as this is what will be used in real-life later.

She's just worried that she won't get the points because we didn't use Eclipse but NetBeans instead. She doesn't understand, that it's just an editor, basically.

Anyway it's a good thing after all. A cute girl, I write her assignments and she sucks my dick.

>>57462550

No, the web based test doesn't work like that.

And it's been 2 years since that test so questions have sure changed. But it's on par with what you would find on sites like Hackerrank or LeetCode.

I specifically remember one of the questions being palindrome detection on a given string. There was another string question I can't recall, and then something with primes.

In any case, they don't ask really hard questions on the web test. The in person test is when they get serious and start asking things like how to implement a hash map or some self-balancing tree function.

>>57462575

The concept of it. You can tell anyone that can follow commands how to use git on a basic level but that goes nowhere close to how to explain to people the model of Git's tree system with branching and merging.

SVN is much easier to explain in that regard.

>>57462608

GUI clients for version control makes things a lot simpler but yeah, Eclipse is a POS that needs to die. I don't use NetBeans but IntelliJ, which is better IMO.

The reason for this is that I want to run it on my raspberry pi and want to be notified about changes to variables via email.

I've googled it and have briefly seen the email libraries available to me in Python, but I don't know if it can work the way I want it to. Again, I don't want to route it through an email service nor do I want to run an email server.

Fuck, im struggling with this really basic java shit. I basically want the first part of a string of a user input to indicate what the user wants, then use the second part to look for a corresponding key in a hashmap. Problem is I cant seem to understand how substrings work.

The C code is a procedure that takes a value of unit type as a parameter.

>>57464602
so ive tried some things but I cant get it to work correctly. I can get this to work:

if (inputcommand.startsWith(params[0]) 

So I can get it to recognize "buy", but I cannot find a way for it to recognize the second part. I've tried endsWith(), but it doesn't seem to work the way I want it to.

>>57465076
No actual representation of any unit value is present in the C's semantics. And no shit it's a procedure, all C "functions" are you twat. In this case it's a procedure that implements a pure function, and pure functions from unit are isomorphic to plain values (modulo strictness, though neither unary function given in earlier posts was strict in its argument).

So I'm making portals in Unity, and I'm trying to capitalize performance gainz

I have cameras rendering portals via pic related, and they're rendering within the red matrix. I want to change them to render in the blue matrix instead. What would be the best way to achieve this? What kind of matrix calculation should I be looking at?
I could simply move up the culling plane to the portal to prevent back-rendering, but I want to go farther- there's just absolutely no reason that I can tell to render all that extra shit that you just won't ever see.

Does GCC unroll loops with indeterminate runtime at compile?

Or would duffs be useful in that case?

Why does it matter if the loop is indeterminate? The loop is unrolled according to set parameters and optimized respectively for cache/CPU.

It's also known as dynamic unrolling.

FUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVA!

Holy fucking shit fuck Java!

They were such simple questions and the only way I could have only fucked every single one of them up if I used java

Question1: You're given a integer and have to find the fastest way to get to that number from zero by incrementing and doubling. Easy! Just while loop in reverse, halving if even and decrementing if odd. Oh, the int is actually a String? Just parse it? Wait, the integer is invalid? Just match /\d+/. How do you do that in Java 7? First you create a pattern to compile it (making sure to write \ as \\), then use the matcher method with the string to get Matcher object, then use the group method to get the match. Oh wait, it returns nothing, because "\\d+" doesn't match and neither does "\d+" or "[0-9]+"

next one is easier. you have a list of non-unique integers and a long. Find all unique pairs that add up to the long. Just use them as hash map keys to remove duplicates, then double-loop through the key list to find the pairs. Oh wait, once they're in the map, using the keySet method returns a set, not an array, and using the set.toArray() method is worthless even if you do casting. It should't even exist!. So now you have to give it a new array inside the array! Wait, are you telling me that some ints can be converted to Integers, but those same Integers can't be converted back to ints? Fuck You!

Final question: you a string containing a char, whitespace, and a fixed-length bit pattern, and also a string of bits. Convert the binary to text. Oh, wait, you need regex again? Fuck YOU!

FUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVA!FUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVAFUCKJAVA!

>>57466323
>Wait, the integer is invalid? Just match /\d+/.
No. You use TryParse.

>Just use them as hash map keys to remove duplicates
>non-unique integers
Completely unnecessary, just do the for loops and get it over with.

>Oh wait, once they're in the map, using the keySet method returns a set
If you are using the keyset of a hashmap you took the wrong approach.

>Wait, are you telling me that some ints can be converted to Integers, but those same Integers can't be converted back to ints? Fuck You!
Integer.intValue. Note that Integer can be null and int can't.

>Oh, wait, you need regex again? Fuck YOU!
No.

>>57466427
>No. You use TryParse.
no, you don't because you need an integer. it's not a fucking option to not get one, and regex is pre-imported

>Completely unnecessary, just do the for loops and get it over with.
no, you don't becuase you need a list of UNIQUE pairs, not all the possible pairs

>If you are using the keyset of a hashmap you took the wrong approach.
then how the fuck do you get the keys?

>Integer.intValue. Note that Integer can be null and int can't.
note that these are all valid ints converted into Integers and back into ints

>No.
Fuck you personally!

>>57466427
yep, >>57466323 has no fucking clue what they're talking about. God damn.

>>57466497
kill yourself you fucking piece of shit asshole motherfucker!

>it's not a fucking option to not get one
What? If it's not a valid int you just make up your own int? What good is that supposed to do? It SHOULD error if it gets invalid input, anything else would be insane.

>>57466488
>you need a list of UNIQUE pairs, not all the possible pairs
You didn't specify that, but just add them to a set then.

>then how the fuck do you get the keys?
You don't. If you ever need the keys from a hashmap then you shouldn't be using a hashmap. You lose the only advantage hashmaps have (O(1) insertion and retrieval) if you iterate over the keys.

>note that these are all valid ints converted into Integers and back into ints
Then there shouldn't be a problem? I think in newer Java version you can even just
Integer x = 5;
int y = x;
So I don't see what you are chimping out about.

>Fuck you personally!
I'm surprised you didn't get hired in spite of your technical failings, with that fantastic personality and willingness to learn from your mistakes.

>>57466576
>What? If it's not a valid int you just make up your own int? What good is that supposed to do? It SHOULD error if it gets invalid input, anything else would be insane.
no, you find the proper number in the string with regex! "100\n" is invalid despite having a valid int in it

>You didn't specify that, but just add them to a set then.
what part of "next one is easier. you have a list of non-unique integers and a long. Find all unique pairs that add up to the long." do you not understand

>You don't. If you ever need the keys from a hashmap then you shouldn't be using a hashmap. You lose the only advantage hashmaps have (O(1) insertion and retrieval) if you iterate over the keys.
I'm sorry, do you have an easier way that's not O(N^2)?

>Then there shouldn't be a problem? I think in >newer Java version you can even just
>Integer x = 5;
>int y = x;
>So I don't see what you are chimping out about.
because I'm getting fucking invalid int exceptions

Can someone clear my understanding of hash tables. Say I have a hash function that is n % 5
If I have a pair (2, apple) (7, banana). When I look in the hash table for 7, how would it know that apple is the wrong one and I want banana?

>>57451610
Can someone halp pls? I'm pulling my hair out over this shit. I'm trying to fetch text data from websites using python and BeautifulSoup, the text comes in fine with the code I have when I use print, but when I write it as a function and call the function it only prints one line instead of iterating through all of the elements in the for loop.

from bs4 import BeautifulSoup
import urllib2

data = open('Input',  'w') 

def fetcher():
    site = urllib2.urlopen('http://www.huffingtonpost.com/entry/donald-trump-white-house-press_us_58249ef3e4b01019814dab06')
    article = BeautifulSoup(site , 'lxml')
    for x in article.find_all('p'):
        return x.get_text()
        
print fetcher()

basically if I replace the <return> inside the for loop with <print> it works perfectly, otherwise it only prints one line.

I need it to return all the text because then I have to write it to a file.


thanks to anyone who can help. I'm
about to commit soduku over this bullshit I'm so frustrated. I cant find anyhelp in either the documentation for BS4 or stackoverflow.

>>57467038
https://en.wikipedia.org/wiki/Hash_table#Collision_resolution

There are many strategies. The simplest is, you insert apple at position 2. You try to insert banana at position 2, notice there's already something there, and insert banana in position 3.

>>57467031
the point was to use regular expressions

started coding an ai for my tic tac toe game. the the bot literally just chooses random places to move. mainly wanted to code it to where it doesn't pic an already spot but the code is broken during a winstate the wil lstill pick?

>>57467061
You can only return once from a function, you can print as many times as you want. You need to concatenate the p segments, or put them in a array, or something like that.

>>57467038
here's the simplest thing
it's easiest to ignore apple and banana for a bit. they come along for the ride
your backing data structure is an array of linked lists
if you lookup 7 you go to position 2 of the array and check if the head of the list has key 7. if not, you follow its next pointer and keep checking

>>57467093
God Bless your soul.

Can you explain why just <continue> won't work though?

Hi /dpt/,

I'm working on my Chip-8 compiler still. Now that my parse tree is definitely, positively correct, I need to find a way to annotate the AST, and later to generate byte code / assembly.

However, I've run into an issue. If I want functions to be separate areas in code to which I can jump to and return from, how do I ensure they don't overwrite registers that the previous function is using? Say, the main function / routine is using registers 1-4 to store data / variables (Chip-8 has 16 registers), and I call jmp to a subroutine which also uses registers 1-4, when it returns, the main function's variables would have changed (because they were in the registers and got overridden). Do I just not use registers at all, or save them into memory? It's not like I have a lot of memory, and not using the registers sounds like a waste...I also don't want to write my own stack implementation since Chip-8's stack can only hold return addresses..

WebM related, it's the parser in action.

>>57467106
return immediately exits the function and /returns/ to executing the caller. After return is invoked nothing is ran from that function until it is called again, where it will be running from the top. If you do want to return multiple values you could return a array, or you could look into turning your function into a 'generator function' where you can use yield to exit to the caller, but when invoked again you start from where you left off, not at the top, sortof.

>>57466937
The GPA thing was reassuring for me. But at the same time it is a little sad how you can be pretty shit at school, but as long as your good at interviews, you're still good to go.

>>57467094
This makes a bit more sense. But If I don't use anything extra and all I have is an array with literal values, then that situation cannot be resolved and I will always get apple instead of banana since I only have a key and it can't tell if the data returned is correct?

>>57467126

Look at an existing implementation and take ideas from there.

>>57467163
See >>57467063

The lookup works by checking 2, if it's a different item, you check 3, and so on until you get to an empty index.

This strategy is generally pretty bad as it has a worst case of just turning your hash table into a list, i.e. O(n) search.

>>57467163
it's unclear to me what you're allowing as "literal values"
at a minimum it seems like you definitely want to use "open addressing" as anon suggests >>57467063. there you have to do more than just provide a hash function

Like banana and apple, I should've just used zip codes and the states associated with them instead for the question. Once you had all your things into the table and began look up using a key, I wanted to know if it was possible to get the banana when you put in a 7 since the initial values I put in were (2,apple) and (7, banana) the 2 spot was taken so it had to be put somewhere else for banana like 3 with just a standard array that had values only in it, banana, apple. I was looking up simple examples of hash tables and noticed that they didn't seem to have code for cases where this happened using only a simple array with values

>>57467309
it's a one-way map (hence 'hash' - hashes don't go both ways), you go from banana to a number, you can't use the same map to go from number to a banana, you'd have to use a separate hash map for that

If you are going to use Java and you are some kiddo or pajeet, just use Python instead, its way more confy and better.

If you are serious and want OOP and want a career just use C++

If you are in the middle ue Cython.

Am I OKish for a junior dev somewhere ? I want min j dev wage, just to start my career off, nothing special, so I have more time to learn and get better at it.

I was able to do both first in Python, then in C++ and now I am trying to see if its any better if I use Cython and libraries for mobile (so far so good)


All in all, I know I can have nice job if I finished my CS meme degree, but its too late now, I have full time job (nothing related to CS tho) so basically, after 1st year I spend another year learning at home, watching lectures at google and stuff, Udemy, Udacity, torrents everything.

Just asking if anyone has any experience, the whole "getting a job" thing seems so far away, I have this gut feeling that even if they let me in for the interview, they will discard me for not having the said degree. Yet I see ppl saying that degrees doesn't matter and you can get a entry level job, and move on even without one, just slower (and I am ok with this).

I think I broke my brain. I understand that java is pass by value but what why do changes stick when you pass in an object into a method?

>>57468568
Because you're passing a reference by value. You can never actually deal with the object itself, it's always a reference.

>>57468568
Imagine you have a gigantic object, hundreds of megabytes. You want to pass that object into a method. Pure pass by value would mean you have to make a deep copy of it and pass that in, spending the hundreds of megabytes of memory again. Not to mention computation power. This obviously isn't what happens.

Instead they pass a value that is akin to points in C if you're familiar. A dumbed down explanation would be something like, every object created gets an ID, that way you just have to pass in the ID and the method will know which object you're talking about, and not have to make a copy of it. Both the terms pass by value and pass by reference are kind of misleading when it comes to this way of passing arguments, for reason I can't be bothered going into.

>>57468568

Object a = new Object();

a points to an object in memory

doSomething(a);

pass a to a method

public void doSomething(Object b){ }

both A and B are now pointing to the object. If the method ends b will be "released" in a way but A still points to object

I need a good way to build up some shit i can actually put on a resume. ie github contributions, personal projects, something. I need to start with some reasonable projects though, my biggest antagonist is my total lack of motivation or creativity. All my best work has been done when I have some serious pressure on me, from classes or similar. Luckily I'll be dead soon if I don't figure something out, so that makes me hopeful that I'll actually be able to get something going.

So what are some reasonable projects to start working on? I want to do projects small enough that I can manage them in a relatively short amount of time, but also not so simple that they're entirely trivial. Basically what are some things I can make or skills I can show that would trick someone into thinking I'm actually employable?

        public Car(String brand){
            this.brand = brand;
        }

    }
}

Output:
Brand of Car Inside main() before: BMW
Brand of Car Inside printBrand(): Maruti
Brand of Car Inside main()after: Maruti

I mean like this example I was looking at, why does the brand stay maruti?

Github contributions to other projects count infinitely more than your personal projects, unless your personal projects grows into something that other people contribute to.

Some projects are more open to others smaller, simple changes. If you can find those just start adding comments, fixing typos, writing test cases, maybe making smaller changes to the codebase itself like better variable names or minor refactoring.

That'll get you in the door before you start writing patches to close issues and such, as that requires some familiarity with the codebase.

>>57466572

Is this open-sourced, anon?

>>57468703

    public static void printBrand(Car car){
        car = new Car("Poo");

        System.out.println("Brand of Car Inside printBrand(): "+car.brand);
    }

>>57468741
Fuck it, I'm just gonna try reading about pointers because that just makes me confused on why setting it to a new object doesn't "save" but changing a primitive does

>>57468711
Well, thats fine and dandy but, what if I made mistake myself, like will they "ban" me from doing stuff on their project or some bad "karma" or something ?

Or as long as I contribute with good heart and learn from my (and other's) mistakes its all good ?

>>57468832
It depends a lot on the project you're trying to contribute to.
I think it's safe to say that 95% will either just outright reject your code with little to no constructive criticism, or reject it with some criticism and that will be the end of it.

The only thing I would stay really far away from, especially right now, is anything political. You don't want your name tied to projects like C+equality or whatever in the current political climate. But I think that's pretty much the only thing that could get you ostracized.

>>57468711

That's what I thought, but I also have no real clue how to effectively find things I can actually contribute to, so I didn't focus on it as much in my post. Any advice? I've seen a couple websites that supposedly track things that are relatively simple and looking for contributions, but they don't seem great. Do I just have to search github one-by-one?

So I read up on pointers, so it has the memory address of where something is so you can mess with things directly.
>>57468741
Why does putting a new object into the space from the pointer not allowed though?

>This is useful as it means you can pass references to the object around, without worrying that someone else is going to change its contents
And what does this mean? Doesn't having a reference mean you do have to worry about someone changing it's contents since it's linking directly to the variable?

>>57469094
Scratch the bottom question, I'm dumb

>>57468703
because car variable of main method and car variable of printBrand method are two different variable but point to same object. Whatever printBrand did to the object should be obtained y every other variable

>>57468741

public static void printBrand(Car car)

before this is pointing to the BMW

car = new Car("Poo");

you removed the pointer from BMW and pointed it to a new Poo one


>>57468789
primitives and objects are just two different things. It's just designed for memory conservation, I dunno if I can describe it more simply, it just "fucking works that way"

>>57469094
>Why does putting a new object into the space from the pointer not allowed though?
That's not what you're doing though. The second
xyz = new SomeObject();
doesn't overwrite the thing xyz was pointing to before. It simply points xyz to a new, different object.

I am bad. How do I fix this?

Why does /g/ hates Java so much?
I'm having fun doing some Spring Boot web stuff like RESTful APIs and MVC applications and now i discover that Java is considered to be absolute evil, and everyone doing Java is considered a Pajeet.

>>57470107
>Why does /g/ hates Java so much?
OOP

>>57468411
You're going to have trouble getting a job in game dev without a degree.

Unlike many areas, game dev requires actual math and CS skills.

Even if you can do enough for the lowest-tier job, they'll be concerned about your ability to progress beyond that.

There's no shortage of skilled applicants; if there was, working conditions would be a lot better than they are.

The only purpose of Java is to hide the futility of a project through abstraction.

>>57470107
> Why does /g/ hates Java so much?
Java enforces the use of OOP, and /g/ doesn't like OOP.

OOP forces you to think about high-level design, which requires that you're at least moderately competent. Like, a few years of full-time programming, which is probably the 90th percentile of /g/'s audience.

If you try to use OOP while you're at the point of having read one textbook and think that ten source files is a large project, it's going to be a clusterfuck.

Also, Java is not exactly "hip". It's a language for people who work in an office and wear a suit. Safety over efficiency, mundane pragmatism over ... pretty much anything, really.

GCC.

>>57470136
I didn't put it right, I do not want game dev job, I actually avoid it, I want a simple 8-5 desk job as a junior dev for a year or so, so I can get in the business, my CV so far looks great, but not related in that field in any matter.

Also CS was my second ba degree that I started (and not finished), I have another one with architecture, that involves math at some degree (I guess not as much, or not the same as CS does). So I am not complete idiot.

Does the faggot startups in the valley count as good opportunities ? Or in that sense, any startup.

C++ does the same, yet /g/ likes it, your argument about OOP is invalid.
C++ also requires better forward thinking and strategy as well as general and in depth OOP techniques.

C++ is superior to Java in OOP and many other aspects. Yet, way more harder to learn.

YET /g/ likes it.

JAVA IS JUST SHIT FOR EVERY PAJEET.

C++ doesn't force OOP.

Also, it's complicated, fast, and dangerous, which give it a certain amount of hipster cred.

But mostly it's the fact that Java forces OOP and a large chunk of /g/ hates OOP.

Disclaimer: I've spent the last 20 years writing C++ code for a living. For the first half of that, Java didn't exist; much of the latter part has been embedded systems where Java wouldn't be appropriate.

Java certainly doesn't warrant the hate from any kind of objective standpoint. Save that for real shit like JS or PHP.

Not that anon, but the information is really easy to do. Just plug into your preferred GUI.

This probably isn't perfect, but only took about 30 seconds because I already have a library to pull 4chan things:

Chan.GetBoard().Boards
    .Select(x => x.BoardName)
    .Select(x => $"{x.PadRight(5)}: {Chan.GetThreadPage(x, 1).Threads.First(y => !y.Posts.First().IsStickied).Posts.First().PostNumber}")

Multiparadigm, mate. That ain't a functional language, and that snippet of code ain't purely functional.

>>57470443
It is purely functional, in the sense that it is exclusively functional. It isn't pure, but it could be

haskell equivalent:

boards (getBoard chan)
& map boardName
& map (printf ...)
& mapM_ print

That's a nice stack you have there.

It'd be a shame if something happened to it.
