You're just naming a random monad and binding it to a function. The code itself is pure because it never says "delete this", it just so happens that the compiler feels those specific monads and functions look special, and makes it so that the file gets deleted when you run the program
>>52126173
So you can still read the file even if it was "deleted"?

This is some next level shit.
>>52126464
C is used much more than C++
>>52126493
The values of "getExecutablePath" and "removeFile" aren't monads. They're values of "IO String" and "IO ()", which are computations doing something and producing a String and (), respectively. IO is the monad, and all the monad part of it means is that these computations can be sequenced in a particular way with ">>=".
You're right that Haskell remains pure since it is basically a DSL for combining impure computations in a sensible way.
>>52126519

This interest me very much. Is there a way of comparing which languages need more energy for common shit? For instance, a comparison of energy of loops between C, C++, Python and Java.
Now THAT would be interesting.
Why isn't I/O considered pure? What side effects does it have?
>>52126699
Make one yourself, I would be interested to give it a glance sometime.
>>52126581
Hm, I agree with you. Not sure what I was saying wrong, really though. IO types are pretty much exclusively used in a monadic manner as far as I know, and sure IO is a monad too. Yes, they get merged into one monad that will be the main function's value, but it's still the original monads being special (and consequently the merged monad being "special" too) that makes the compiler put the delete part in the executable

From what I understand, any thing explicitly causing changes in the "outside world", apart from describing how to obtain the result of the program (obviously code execution has to cause changes too, but those don't count because you don't explicitly ask for those changes), is considered as having a side effect.

>>52126717
Haskell's IO is a bit of a misnomer, since it encompasses all possible side effects. Even then, just writing data from standard input and writing data to standard output are side effects. Loading and storing values from somewhere in memory are side effects. Anything that isn't "map this value to this value", i.e. a mathematical function/relation, is or has a side effect.
>>52126727
The problem is that you're using the term "monad" incorrectly, which further adds to its "mystique". If it's not a functor with return, join/bind, and the laws, it's not a monad. So IO is a monad, but IO a or any value of that type are not.
>>52126882

Ah, I think I read you. "Monadic value" would be the correct term if I wanted to talk about IO values, right?
>>52126743
>not using tadpoles
>>52126956
Exactly. But there's nothing special about them.
The only thing in common with all the instances of the Monad type class is that they are all instances of the Monad type class. Do you get what I'm trying to say here?

>>52127413

not easier when you have real applications that involve more than few variables and functions
>>52127383
So you don't needlessly create new variables to represent a different type version of a variable. For example, you might want to have an int that stores a number and you can manipulate it using mathematical functions, but then loop through it using the string representation of it. Having strNumber and intNumber is needless and wastes space on a sizable program
Additionally, storage type have individual restrictions on them for good reason, but you may want to cast them into another type to bypass this restriction.
>>52127449
>Having strNumber and intNumber is needless and wastes space on a sizable program
it's literally one line of code to declare a strNumber in addition the intNumber
>>52127487
To declare, yes, you absolute nob. Is that all you do with variables? jesus christ laddie
>>52127449
String 5 and Int 5 are completely different things. Besides, you're confusing dynamic and weak typing, both of which are shit BTW

You will double the memory for each variable call, George. If you do this shit with something that uses that line of code intensively, you will lose ALOT of memory quickly. Also, enjoy your memory leak.

Why do people actually develop on OSX? Why dont they use linux. In all my experiences, OSX is such a pain in the ass to setup a development environment on because of this xcode bullshit. Not only that, but Apple manages to break cmakes for a shitton of libraries every single time a new version of OSX comes out. Not only that, the lack of a centralized repository makes it a pain in the ass to find shit. Yeah you can install brew, but why cant OSX come with something similar by default? Also, why is the terminal so fucking slow on all the macs i use. I've noticed that the cursor speed on osx terminals is so unbearably slow.
If you use linux, everything you need is just there, you dont have to dick around on the internet and spend an hour setting up your development environment.

So socket programming such as above is supposed to be done in Linux, but is possible in Windows. I've been trying to follow this guide but it's been a nightmare, and I'm considering dual-booting for my personal ease. Whats the best flavor of Linux? How is Gnome comparatively?
>>52128081
is that bailey in the frame?
>>52128001
Most people don't develop for the sake of developing, they develop because there are certain kinds of things they want to make. Many developers are mobile and/or web developers. Mac is great for this, firstly because it's the only OS you can do iOS development on, but also there are a lot of great web dev tools available for it. It can run pretty much everything Windows or Linux can run that a developer would want, except maybe visual studio. So why constrain yourself? If programming is your job, the price of a good mac isn't a big deal if it helps you do your work easier.

iOS is one of the most popular mobile platforms. iOS devices have a limited selection of devices which enables you to have tried and tested full compatibility for all relevant use cases. iOS users are generally more willing to pay for software than lagdroid poorfags. i'm not even iOS shill but seriously it's just another platform. you can even take an android app and reuse most of the code on iOS using roboVM.

I'm personally an iOS and Android dev. I don't do it because i think the stacks are great, i do it because I'm passionate about making nice apps.
Also just about every well paying job is going to involve using some naff technologies, unless you are extremely good. I could earn much more as a web dev, but it's not an area that interests me as much.
I was wondering why a function become 2x slower with optimizations ON, turns out Microsoft's memset() implementation in msvcrt.dll (the libc that's always available, used with winddk)07FEFE0258E3h:
movnti qword ptr [rcx],rdx
movnti qword ptr [rcx+8],rdx
movnti qword ptr [rcx+10h],rdx
add rcx,40h
movnti qword ptr [rcx-28h],rdx
movnti qword ptr [rcx-20h],rdx
dec r9
movnti qword ptr [rcx-18h],rdx
movnti qword ptr [rcx-10h],rdx
movnti qword ptr [rcx-8],rdx
jne memset+148E3h (07FEFE0258E3h)
wtf? Write combing for something you almost surely are gonna use later?
A naive unoptimized C loop is:
~180000 cycles
that garbage:

And yet, you haven't got one.
Can you describe the syntax and semantics formally rather than a bunch of botched up examples that I don't care to try to figure out myself?

I actually do. I'm only here because I didn't plan anything for my holiday

Not built-in, but as a library why not?

I really think you don't understand how the C preprocessor works.

Well you can never have a fully correct GC in C because of unrestricted pointers, and any time you call into some code which was never built with that GC in mind all all hope is lost (including standard libc).
>>52128500
A garbage collector requires:
1) a root set (list of base references)
2) a collection routine
This have to be part of the language syntax/semantics, almost impossible as a "library" for C. Maybe C++, but not C without it being really janky (and not worth it, pretty much the only reason you'll ever use C is because you don't want a garbage collector. I can't think of a good reason to use C+GC over any other language with a GC)
>>52128689
>I can't think of a good reason to use C+GC
Triggering autismo-trons.
It's made me think, though:
Since C and C++, pretty much every single language afterwards has been managed (without explict word not to be, e.g. unsafe{}).
Why is this?
>>52128795

>>52128795
>C and C++ are now considered "unsafe" languages
>>52128795
Because nobody is bigger than the userbase of the language they use
>>52128823
they have always been unsafe
>>52128823#include <iostream>
int main () {
int* foo = new int[3];
delete[] foo;
std::cout << foo[0] << std::endl;
return 0;
}
Would you call this "safe"?

If you wanted to win over C/C++ users, wouldn't you want to do so with an unsafe language?

>i want this memory

but they literally had to define an entire language like java and C# because people were just too fucking stupid to comprehend that once something is destroyed it is fucking gone so pointing to the place where it once was expecting it to be there doesnt make sense
>>52128863
You realise you can have a language with both manual memory management AND garbage collection, not just as a switch but AT THE SAME TIME?
>>52128875
Fucking idiot who has never worked with pointers, you won't always know whether the thing you're pointing to has been deleted or not
>>52128875
What's the largest program you've ever written?
Recently made a programming language, had to implement algorithm-J type inference, it requires "type variables" to appear multiple times throughout type signatures, and for them to be "assignable" so that they'll all simultaneously convert to the new type.
Super easy memory management, right?
>>52128881
It's certainly possible but the recent trends have shown that language designers don't want to create it.
>>52128850
>what is std::unique_ptr
if you're going to be picky about manual memory management at least bully C instead

btw manual memory in D is really shit
>>52128881
It's a shame no one designs their language around memory arenas (nested, hierarchical, stacked, etc) with convenient syntactic sugar.
I find them to be the perfect sweet spot of fine grained control and "allocate and forget" type management (and it's often what I use and implement in C, but with somewhat verbose syntax).
>>52128984
You just use malloc and free you retard
>>52128943
course, but what kinda shit can I create that uses that information?
>>52128960
Shared objects that have to keep track of eachother. Pretty trivially implemented using reference-counted pointers and weak references, but it's certainly not as trivial as >>52128875 makes it all sound.
Even if manual memory management "isn't that bad", when you DO accidentally memory leak / use-after-free, it can become hellish to debug and impossible to spot.

But that can be said even for safe languages, you can, for instance, crash the Python interpreter just as easily as you can crash a C++ program.
>>52128949

>>52129060
>one that manually allocates any class and one that deallocates any class
malloc and free?
Maybe calloc if you want zero initialised or some shit.
>>52129068
>you can, for instance, crash the Python interpreter just as easily as you can crash a C++ program.
I wouldn't say "just as easily."
I've never had a segfault in python code (I'm sure it's possible), yet I've had tons in C++. Specifically, I was having problems where I kept accidentally creating indirect infinite recursion. gdb was helpful, but "error in function Unify(...): call stack exceeded" (what Python would've told me) would have been a lot more helpful than sifting through template instantiations after a fat "Segmentation Fault"
>>52129205
Yes but I was objecting the point that no language safety can save you from shooting yourself in the foot rather than one's lack of understanding a language they write in.
>>52129110
C++ is a million times better for manual memory than D

Why would I allocate memory for a class? I think you meant object btw.

You said 'allocate', which malloc/free does.

This
Or 2-clause BSD
>>52128944
GPL is the only license that cares about your freedoms desu senpai
>>52129238
Allocates a class... which means the constructor/destructor should be called.
How is that moving the goalposts?
>>52129284
>which means the constructor/destructor should be called.

>>52129297
Ok you complete stupid fuck so you're saying you can't do manual memory allocation for classes in D but that's completely fine because you can at least make storage space for them that you can't safetly use
>>52129300
D isn't C, and C++ isn't C

So what's the equivalent of the F# pipe operator in Haskell? . ?

>>52129419
z |> f x y

you can do pipelines like
x |> f1 |> f2 |> f3 |> f4
>>52129419
take the value of the expression before |> and passes it to be the last parameter for the function after |>. Makes code really readable and clear. Take fizzbuzz for example:[1 .. 100]
|> Seq.map (fun i ->
match i % 3, i % 5 with
| 0, 0 -> "FizzBuzz"
| 0, _ -> "Fizz"
| _, 0 -> "Buzz"
| _, _ -> string i)
|> Seq.iter (printf "%s")
so this code is easily readable as:make a list containing number 1 to 100
map it to a list of fizzbuzz strings
print each of those string
it makes it nice and logical. And i didn't need to create any variables or mutation of any kind to make the steps read from top to bottom like i often need to in other languages. It generally helps you avoid nesting loads a function calls inside each other.
