animal *arr[10];

}
for (int i = 0; i < 10; ++i){
    cout << "arr["<<i<<"] says " + arr[i]->sound() << endl;
}

Why is this working? Shouldn't the variables go out of scope at the end of the first for loop, leaving the pointers dangling?

They've given up on significantly improving the JVM performance through JIT optimization, they're actually focusing more on making the JVM even more bullet-proof by allowing developers strip it to the very core; we'll be having a <10mb JVM soon.

Is c++ primer 5th edition fine or should I read some book that covers c++14?

What do you guys recommend? gulp, grunt or brunch (besides bower which is basically a must for easy management of client side extensions like modernizr, browserify, etc as bower components). I'm looking for a generic solution that plays well with any client side stack (backbone, angular, knockout, react, vue, meteor, etc).

In Haskell, if I use pattern matching to deconstruct a data object, then return a constructor with all the same arguments, am I duplicating that object? Is there any way around that?
Like this
A b c d
| b == 4 = A b c d
| otherwise blah blah blah

If you're still here and interested, I uploaded it to Github now.

https://github.com/forbjok/chandler2

You will need to clone and add-local a few dub packages, as they are not in the dub repository (yet):
https://github.com/forbjok/reurl
https://github.com/forbjok/jsonserialized
https://github.com/forbjok/dstatus

It's reasonably usable at this point, but completely devoid of any documentation yet, and I haven't gotten around to properly handling transport errors (connection loss, http errors, etc) yet, so I don't know how it will react to those.

In short summary, you can specify any number of urls as commandline arguments, and they will be downloaded. If you want it to watch one or more threads indefinitely and add new posts, give it one or more "-w <url>" arguments. For watching threads, the interval at which it checks for new posts can be set with "-i <seconds>".

> am I duplicating that object?
Who cares?

A fundamental feature of pure functional languages is that there's no such thing as "identity" for values. There's no difference between copying a reference and duplicating (cloning) an object (unlike e.g. Java where you have == and .equals() and it matters which one you use).

How do I stop being a perfectionist?
I keep rewriting my code. The code itself is fine, but I keep nitpicking on trivial shit like whitespace and documentation. I've come to a point where I d on't even bother writing code anymore.

> Who cares?
Yeah, you don't care until your first contact with reality, and then you start to use unboxed types, force evaluate lazy trunks and doing lots of magic just to get close to 1/10 of C performance.

How do I get good at Java? Everything I try without a step by step tutorial doesn't work. I even tried copying someone's code on github to base my code off of that, but I couldn't find anything useful.

>>52904325
Why don't you try writing something non-trivial, preferably something outside of your comfort zone.
You'll be too frustrated to worry about mundane shit like formatting and documentation.

>>52904421
read a book

>>52904443
That's what I tried. I stopped writing C++ and started learning Go. That didn't help. In fact: it got even worse. It's so bad it even affects me at my job.

>>52904519
I can suggest one of two things.
Stop working harder than you need to.

And get yourself checked out, you might have actual OCD if this is starting to disrupt your capacity to work.
Do you experience this in any other aspects of your daily life?

>>52904518
i don't know how to read.

>>52904567
/self

>>52904366
If you want C, you know where to find it.

Unboxed types, strictness annotations and concerning yourself with the precise evaluation strategy of a specific implementation should be reserved for the specific cases where optimising a (very) small proportion of the code brings significant gains to the entire program.

If you end up doing it a lot, you're probably using the wrong language.

>>52904558
>you might have actual OCD
I'm pretty sure I do.
>keep checking if the door is locked
>keep checking if all the right items are packed
>nail biting (not really OCD, but more an anxiety thing)
I don't think getting myself checked out is the right thing to do. I have to figure it out by myself. Maybe some obscure shit like meditation helps me out. Or go completely out of my comfort zone and learn something like Haskell or do more math stuff in programming.

>>52904633
that's normal, you're just insecure over whether you did something correctly

true OCD is when you start experiencing irrational thoughts and/or fear if you don't do some compulsive behavior

What's the best way to learn x86_64 assembly? I already know one assembly language (AVR), but I realize x86 is much more complicated.
Seems like a lot of the assembler books in the Gentooman's Library are for 32-bit x86 only and explain all the terribly useless cruft x86 carries with it. Additionally they are usually completely tied to Windows. Anybody have a good book that's OS agnostic and 64-bit focused?

Threadly reminder that you should not refer to the act of programming as coding. It is improper and makes you look like a 16 year old

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
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

It's easy. You just don't understand how if-else statements work.

   if (a == b)
        c = 10;
    else if (a > b)
        c = 20;
    else
        c = 30;

is quite literally

if (a == b) {
    c = 10;
} else {
    if (a > b) {
        c = 20;
    } else {
        c = 30;
    }
}

'else if' doesn't actually exist as a construct. Does that help you see how they should be nested?

Trying to make a stupid WinAPI function work.

Anyone familiar with Oracle Application Express offer me some advice. I've installed Oracle Express and installed Apex and can access the Administration services. However when I go on localhost:8080 I am asked for authentication. I can get pass XDB with System and passord however with the Apex authentication it never goes through. I tried resetting the password following this guide http://blog.mclaughlinsoftware.com/2011/09/14/reset-11g-xe-apex-password/ and using the user rest password in administration but I still can't get past that screen. Scrub question I know but I am really stumped. Anyone got an idea of what I should be doing?

Javascript is a pass-by-value language. I'm trying to understand how parameters and arguments work with one another in a function.

A parameter is a variable. When we pass an argument to the function, we are passing the value referenced by that argument, and assigning its value to the parameter.

So, when argument = 3 is passed to the function, it's like saying
var parameter = 3;
Is that right? Would something like this be permissible within a js function:

function foo(param) {
  param = param + param;
  return param;
}

What I suppose I'm trying to figure out is if param acts as a variable within a function, holding (initially at least) the argument value, or if it's almost like a blank space that is "filled in" by our argument value. Like, it's not really a variable holding a value, it's just a value. In the case above, we wouldn't be able to assign param + param to param, because it'd be like saying "10 = 10 + 10". 10 isn't a variable there, it's just a value.

I'm so fuckin tired bros

>>52907513
when you do param(x) you pass the value of x into foo which is assigned to variable param. if x is 10, param is also set to 10. param is a variable, you can reassign it if you want.

The first time I saw ternaries I basically bundled it with goto in the "thank fuck we don't have to use this shit any more" pile.

A single ternary isn't actually that complicated and occasionally has its benefits, but the second you are nesting them you should really just be using if blocks.

If I have a function recursively call itself, when it finally returns will it return the value from the last called function?

E.g.

function foo(param) {
// code
if (something) {
 foo(param); // call self with argument passed to param at start
else {
return foo;
}
}

>>52907987

But it is useless, nobody will use it, it was just a project.

>>52908106
you have to put a condition at the start like

        return param;
    else
        a = a + foo(param-1);

I hope you defend yourself.

>>52908135
That is not definition of recursion. A function can return nothing at all and still solve something recursively.

Sill missing the point mate. You want the result of "foo" to be on the stack. You can only do this by returning the result of the call all the way back up the stack.

function foo(param)
{
if (something) return foo(param);
return param;
}

why is there no modifier in java to make a field read-only for everything outside the class?

let me explain:
obviously you can do it with getters, however, it's just ugly. even uglier if you need to use getters for static field.
Let's say you have a class that maintains one static field (like a vector with the mouse coordinates) and 5 classes that need sad value from time to time.. now, if you use a getter to return the value you have an ugly function that does literally nothing and even more ugliness in the classes utilizing said value. call me autists, but this really bothers me.

clear and now fucking mess of brackets. and it's clear that you get the untampered value. you don't necessarily know what's happening in the getter.

>>52908991
non const static fields are cancer. you are probably a shitty programmer that can't organize his classes.

>>52908864
It's by design, so you can just change stuff in the getter/setter later if you need to without having to change things in other classes.

autism is strong in you.

>>52909415
Just to close the case on this. A getter is literally only used to return a private value untouched. You are not writing getters.

This has been OOP 101, thanks for attending.

>>52908864
if youre doing this you probably want a getter and a setter so you can define them as synchronous so you get thready saftey.
>>52909430
yes. an object should expose interface possible. getters and setters should often be left out.
>>52909457
now we're just being pedantic

>>52909457
every function with a "get" in the name and return a value of private member is a getter, duh. And look: it doesnt say it must be unaltered.
but doesnt surprise me that some raging autist appears to discuss semantics he learned in first two weeks of college.

>>52909516
That is literally the definition of a getter. No pedantry involved.

You should be using a proper getter then converting elsewhere.

>>52909457
not necessarily. getters/setters can do more than that. getter can do a null check and initialize a variable for example. or setter can back up the value in database.

I don't blame you though. that is probably what your collage teacher taught you.

>>52909532
Yes. The return of a private value. Notice that it says return and not modify themn return.

>>52909563
Never will a getter ever need to do those. The checks should be done from where the getter is called.

>>52909563
>collage

uh-oh

>>52909563
>collage

Lol

>>52909570
no. that's what you infer from the word "return".

>>52909587
didn't you just defend encapsulation 101? do you even see what kind of mess this approach would create?

>>52909621
I'm not sure a null check when calling a getter is messier than whatever bullshit return value you get when your "getter" detects null.

>>52909648
It is just an example. In that way you ensure that an object is not initialized unless you use it. Can be useful.

At our job, one the classes has getters that recalculates the value when they are dirty. Instead of recalculating them everytime we change something, it simply does they when they are actually being accessed. Way more efficient this way.

>>52909648
let's do a thought experiment with your method:

class Foo{
private Object dildo;

public Object getDildo(){
return dildo;
}

public void initializeDildo(){
this.dildo = new Dildo();
}

}

now another class:

class YourAss{

public void insert(){
Dildo dildo = Foo.getDildo();
if(dildo ==null){
Foo.initialize();
dildo = Foo.getDildo();
}
doStuff(dildo);
}
}

now imagine you have 20 different classes accessing that field and you have no way to tell what class will be the first one. you will have to add this code every single class and create a huge blobb of decentralized bloat. and that's just for one getter.

Hello /g/. I'm a newfag trying to teach myself programming. I'm working in Python. I'm having a confusing problem and I was wondering if you guys could offer some assistance.

I'm writing a wrapper around the API for this chat client me and my friends use. My goal is to create some function that lets you choose who to post as and whose icon to use for posting, then you enter your message and it posts all that to the appropriate channel. It's sily, but it'll be fun when it works. I have this figured out in a basic form (IE the user can't choose, I just put all the information in ahead of time) but the issue is having it change everything dynamically based on user choice. You can query for a dump of information on all of the users, but users each have individual IDs aside from their usernames (IE "userid = 5e34tgr34, then a line later, username = anon") and the API commands function via userID, not username. I need to find a way to associate the names with the IDs so that the user can put in "anon" and the program will know I'm addressing "5e34tgr34".

I don't want to just go through the list manually and create a library by hand, because I'm not sure if the userids change (though they probably don't), and because that feels like a copout. What do you guys think is the most graceful way to approach this? I've never really parsed an information dump like this before so I'm a bit confused.

So far my best idea is to have a super long loop that goes through the entire info dump and finds and matches every instance of "userID" with "username", then puts all this information in a library which the rest of the wrapper references back to. Is that too cumbersome?

that's fine
>I'm not sure if the userids change
if they do, the api is shit

Indeed you are correct, the objects which are referenced by the pointers in the array are no longer in the for loop scope and are "freed". However since they are on stack, being freed doesn't mean being cleaned, it simply means that now any other variable that needs that memory address is free to use it, since you have no other assignments operations those particular addresses in your pointer array have probably not been used yet, but if you make a couple of call to functions and assignments between the first and the second loop chances are that those pointers will be pointing to garbage.

that thinkpad. Also OOP is used in lots of places you probably already use it and you just choose not to acknowledge it.
