I am going to redpill you about the GPL.
Some cucks (among many we have) are trying to promote BSD, MIT, Apache and other licenses because they are hired by corporations that can make privative software thanks to those licenses by putting some closed source on top and fuck everyone else.
For example, Darwin is an operative system in which Apple collaborates with the "open source" community. Because it is a BSD derivative, Apple uses that operative system and put it some closed source bits and call it OS X.
Sure, you can use Darwin, but is crippleware, is of much lesser quality. And Apple is not even full fascist here, they at least have some degree of cooperation. Microsoft on the other hand in the 90's spread memos about how to fuck up Linux and the free as in freedom community. Is called "embrace, extend, extinguish". See for yourself: https://en.wikipedia.org/wiki/Embrace,_extend_and_extinguish https://en.wikipedia.org/wiki/Halloween_documents
If you were in charge of Microsoft, and you had no ethics, what would you do knowing that you could harm the free software community just by reusing "open source" software in your favor, put some bells and whistles, and extinguishing the original product?
I beg you consider the GPL and LGPL over everything else. One can't possibly know what is being used under the hood of many privative software, and you never know when something "open sourced" sometime ago is now part of closed source software.
Even the LGPL, because you can have a fully functional application in LGPL which someone can cut off the interface, put a privative interface to it and deprecate any other interface by changing the API (systemd?).

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.
Many users do not understand the difference between the kernel, which is Linux, and the whole system, which they also call “Linux”. The ambiguous use of the name doesn't help people understand. These users often think that Linus Torvalds developed the whole operating system in 1991, with a bit of help.
Programmers generally know that Linux is a kernel. But since they have generally heard the whole system called “Linux” as well, they often envisage a history that would justify naming the whole system after the kernel. For example, many believe that once Linus Torvalds finished writing Linux, the kernel, its users looked around for other free software to go with it, and found that (for no particular reason) most everything necessary to make a Unix-like system was already available.

is Hurd an attempt to make a complete OS with non-Linux kernel?
>>52997967
I’d just like to interject for a moment. What you’re refering to as Windows, is in fact, NSA/Windows, or as I’ve recently taken to calling it, NSA plus Windows. Windows is not an operating system unto itself, but rather another locked down component of a fully functioning NSA system made useful by the NSA corelibs, shell utilities and vital system components comprising a full OS as defined by the government.
Many computer users run a modified version of the NSA system every day, without realizing it. Through a peculiar turn of events, the version of NSA which is widely used today is often called “Windows”, and many of its users are not aware that it is basically the NSA system, developed by the NSA.

You really need to learn to figure things out even though you don't "want" them. Its not that you should sustain an 8 hour coding spree, but change something every day.
If its not code, write some documentation, or refactor variable names.
Even if its only three lines you just have to push yourself to start it.
Got a weird bug, which I'm pretty sure is a logic error on my part Language is Swift.
When I run this code in a Cocoa interface, it saves the value as a string and makes it the placeholder text instead of writing the value. The weird part is when I open the window back up, that value is the placeholder text, and when I submit it, it takes the value, just like I want it to do the first time around.
Effectively it causes a user interface bug where the user would have to save the api key, close the window, open it again, and click save again. Kinda weird.

What's the simplest way to build a web application using C#? I know almost nothing about web development.
Ideally I'd be able to use something similar to the WPF framework when it comes to design, writing some XAML with a view to guide you makes life lot easier, and data binding makes the whole process a breeze.

foldr applies an aggregation function to a list. For example, in pseudo code:foldr(function, list, initial) {
agg = initial;
for i in list:
agg = add(agg, i);
return agg;
}
foldr(add, [1,2,3,4] 0) = 10
foldr(add, [1,2,3,4] 1) = 1
It is important because it demonstrates a language ability to turn a list structure into a function structure.

> Still not sure why it is called foldr.
The generic term for the operation is "folding" or "a fold" (sometimes the terms reduce or accumulate are used).
The "r" is because it's right-associative, i.e.
> foldr (+) 0 [1,2,3,4]
evaluates as
> 1+(2+(3+(4+0)))
whereas
> foldl (+) 0 [1,2,3,4]
would evaluate as
> (((0+1)+2)+3)+4
If the operation isn't commutative, the distinction affects the result. If the arguments have different types, it affects whether the expression is even valid.
Also, if the function is a type constructor, foldr can be applied to an infinite list to yield an infinite list (or other structure) which will be generated lazily.
>>52998800
cool double dubs.
I'm not the anon you just responded to but I have a question.
I can see how functional programming would be very useful when dealing with processing large amounts of data, but that isn't what my normal programming usually entails. I do embedded systems programming where pretty much all of my code is either having an affect on the real world, doing some IO, changing some state, or quickly deciding whether to do any of these things. Do you know of any resources that could explain how functional programming could fit into this scenario? Or does it not really?

It isn't built into the language, it's a library function.
It's trivial enough to write it yourself, but given that most iteration is either a map or a fold, it makes more sense to just use an existing function rather than explicit recursion.
Similarly, generalised iteration is a library function, rather than a language construct:iterate :: (a -> a) -> a -> [a]
iterate f x = x : iterate f (f x)

>I hate when functional fags make stuff sound more complicated than it actually is
You can't write papers about simple things, so they invent nonsense like zygohistomorphic prepromorphisms because it makes them sound smart.
It's like when people sound "clever" for saying "x = x + 1" doesn't make sense.
Here, "x" is something like "the temperature."
The temperature is 90 degrees.
The temperature is rising.
Is being able to refer to the temperature as a concept separate from its current value meaningless? Of course not.
The key is understanding that both uses of "temperature" and both uses of "x" are different.
>>52998962
> How can you foldr an infinite list? You start with the infinite-th item
A right fold starts with the first item, with the recursive case on the right.
Note that for an infinite list, the base case never gets invoked.
Given:foldr :: (a -> b -> b) -> b -> [a] -> b
foldr f z [] = z
foldr f z (x:xs) = f x (foldr f z xs)
Considerfoldr f undefined [1,2,3,4,....]
= f 1 (foldr f undefined [2,3,4,...])
= f 1 (f 2 (foldr f undefined [3,4,...]))
= f 1 (f 2 (f 3 (foldr f undefined [4,...])))
...
In order for this to be of any use, the function needs to be non-strict in its second argument (which is true for any type constructor unless it has a strictness annotation, but not for e.g. primitive arithmetic operators).

You mean other than letting you just tell the computer what to do rather than having to spell it out in minute detail in a language that's one notch above assembly?
If you think that imperative programming is actually easier, then you've been mentally crippled beyond hope and should probably just top yourself.
>>52998942
>>52999049
I'd say that reduction (or elimination) of mutable state actually is one of the key points to functional programming, because without that, why would people bother with the overhead in memory usage and all those "weird" (to non-fp programmers at least) idioms in the first place?

>Algebraic data types:
aka tagged unions, they are not a property of FP.
>>52999113
This claim was proven wrong more than 30 years ago.
All of the fastest parallel systems, like those massive supercomputers and distributed computing projects, use imperative languages.
You can also use the "no side effects" style of programming in any imperative language. Some imperative languages like PL/I, Fortran, and Ada have attributes for saying a function/procedure has no side effects.
The hard part is getting information to and from different local memories (computers, address spaces, caches), which imperative programming is better at doing.

The syntax for the second example comes from FP.
Pattern matching:
sequelstring messageToString(Message m)
{
switch (m.tag)
{
case emsg1: return tostring(m.m1.first) + "," + tostring(m.m1.second);
case emsg2: return m.m2.first + ": " + tostring(m.m2.second);
case emsg3: return "exit";
case emsg4: return "[" + tostring(m.m4) + "]";
}string messageToString msg =
match msg with
| msg1 first second -> tostring(first) + "," + tostring(second)
| msg2 s i -> s + ": " + tostring(i);
| msg3 -> "exit"
| msg4 c -> "[" + tostring(c) + "]"
// an ADT implicitly provides "reverse constructor" patterns

I love commies pretend that everything they're doing is "for the proletariat" and that their subjects are in total agreement with them because:
1. The only people left are those who agree with the plan, those who opposed communist takeover have been slaughtered
2. The only reason the remaining people are working together is because they'd rather be pushing bodies into ditches than be the bodies IN the ditches.

The next time you come up with a novel software technique, you have an inherently monopoly on it unless you intend to publish it for free.

The 'common solution' /g/ trumps is actually FROM there.int avg(int a, int b) {
return (a / 2 + b / 2 + (a % 2 + b % 2) / 2);
}
>>52998187
kek
>>52999784
it's not correct for all values of a and b. you have to do something likeint avg(int a, int b)
{
if(a > 0 != b > 0) {
return (a + b) / 2;
}
return a / 2 + b / 2 + (a % 2 + b % 2) / 2;
}
Does anyone have that list of programming tasks for beginners? It was quite long and the projects gradually escalated from simple to difficult. I saw it floating around awhile ago.
>>52999641
>obviously supposed to return an int
>50% of use cases, int cannot store required accuracy.
Sure thing m8. Without first defining which rounding method you want to use, the question should only ever be interpreted to mean return a FP type.
Returning the average of 2 ints as an int, without further details about what to do with odd sums, is meaningless.

I can't remember anything post elementary school arithmetic, but wouldn't be it a prime if It can be divided by 3 and 5, right?

>>52999763
>>52999756
>>52999752
If you spend more than 30 seconds writing a for loop with exceptions for 3 and 5, you still fail.
Missing 3 and 5 is a bad slip, but at least it's not full-blown Prajeet mode.
>>52999922
3 and 5 are primes and they are still multiples of 3 and 5
every prime is divisible by itself and 1
How do I learn JavaScript senpai?
>>52999922
A prime only has 2 factors - 1 and itself
So if it can be divided by 3 and 5, it is not a prime
The only prime divisible by 5 is 5
The only prime divisible by 3 is 3
