"Since the dawn of history the Negro has owned the continent of Africa – rich beyond the dream of poet’s fancy, crunching acres of diamonds beneath his bare black feet and yet he never picked one up from the dust until a white man showed to him its glittering light.
His land swarmed with powerful and docile animals, yet he never dreamed a harness, cart, or sled.
A hunter by necessity, he never made an axe, spear, or arrowhead worth preserving beyond the moment of its use. He lived as an ox, content to graze for an hour.
In a land of stone and timber he never sawed a foot of lumber, carved a block, or built a house save of broken sticks and mud.
With league on league of ocean strand and miles of inland seas, for four thousand years he watched their surface ripple under the wind, heard the thunder of the surf on his beach, the howl of the storm over his head, gazed on the dim blue horizon calling him to worlds that lie beyond, and yet he never dreamed a sail.”

tripfags don't belong here. i'm yet to see a single decent tripfag and i've been here for a loooong time.
mind you, trips shouldn't be just turned off, instead people that attempt to use a trip should be instantly permabanned- as a way of sanitizing the board. you know, the way of /fur/

well yes, i miss noko too and those are shit changes. visible sage is much needed as right now 4chan basically caters to various faggotries blooming like mold.
>>52066930
There was no point in the email field as we can use the comment field to write the email. Getting rid of it freed up a non-negligible amount of resources every year.
>>52066657
here's what i came up with#!/usr/bin/octave -qf
if (size(argv())(1) < 1)
printf("Usage: swastika STRING\n");
return;
endif
function [ y ] = swastika ( x )
x = int8(x);
xx = [fliplr(x) x(2:end)];
len = length(xx);
vert = [zeros(len / 2, len); xx; zeros(len / 2, len)];
horiz = vert';
bottom = [zeros(len - 1, len); x, zeros(1, length(x) - 1)];
left = rot90(bottom);
top = rot90(left);
right = rot90(top);
sides = bottom + left + top + right;
y = char(max(32, max(sides, max(vert, horiz))));
endfunction

I think we should all sport a trip. It would make /dpt/ more fun.
>>52066992
Only because everything is logged for the sake of delivering the data to the NSA. If that weren't the case, it wouldn't matter, but the email field was useful since it could be used for various shenenigans.
>>52067012
I agree
This is meant to reverse the words on each line of a file but it doesn't quite work#include<stdio.h>
int main(int argc, char * argv[])
{
FILE *file = fopen(argv[1],"r");
char line[1024];
while(fgets(line,1024,file))
{
int i = 0; int j = 0; int k = 0;
char words[100][100];
while(line[k])
{
if(line[k]!=' ')
{
words[i][j] = line[k];
j++;
}
else
{
i++;
j=0;
}
k++;
}
while(i>=0)
{
printf("%s ",words[i]);
i--;
}
printf("\n");
}
}
Why doesn't someone try to "fork" C++ and remove/improve the legacy nonsense(different symbol for the pointer compound type and the dereferencing operator, prettier pointer to function syntax, etc.)?
>>52067016
Is the comment field not good for those shenanigans?

Trips have a use, though. Not the way tripfags abuse them here, but still.
Tripcodes exist to be used as a temporary ID to be recognizable in a large discussion if/when it's relevant. When a discussion is done you throw your trip away.
Automatically permabanning all tripcodes would be retarded.

Well that's pretty fucking shit then, innit? It doesn't correctly infer that x and y are ints (or a generic Number class).

no shit sherlock, there nothing to infer since it's resolved in the dynamic environment, but the jvm's JIT compiler could fix that at run time.
>>52067630
Looks like simple bresenham circle's algorithm to draw the circle using a diameter of length - (word's length - the 3 interlapping points + 4 to keep it around the swastika) or a diameter of word's length+1. The swastika bit should be easy.
I reckon rather than printing it line by line (which might be somewhat possible). It might be easier to just store it all in an array before printing it as you'd have to calculate for both shapes at the same time
GDB actually works bretty gud with Go. Didn't expect that.

Meanwhile any decent language can perform the inference, thus kawa's type system is absolute dogshit.
>>52067817
Modern C++ uses GC or reference counting. GC is much faster than reference counting, hence D is better in that regard. Moreover, the GC can be removed temporarily when it matters.
>>52067838
>Modern C++ uses GC
OHOHOHOHOHO
>>52067838
>Reference counting
>Slow
Only if you use the C++ std::shared_ptr because it uses atomic operatons and memory barriers to be thread safe. A non-thread-safe reference counting will be faster than GC any day.
>>52067855
>>>/tumblr/
>>52067860
Top fucking kek.
>there are people who actually believe this
Even shitty GCs like boehmgc are significantly faster than reference counting.
>>52067826
you missed the point, if you ask to disassemble(define (f x y) (+ x y )), the compiler could only give you a generic version because you haven't provided any arguments (= nothing to infer). compiler infers when a function evaluation is made, like in(define (f x y) (+ x y))
(f 4 5) ; arguments type is know, can infer this
that's basic stuffs.
>>52066499
will it halt?
>>52067888
Just because you're inbred doesn't mean reality needs to become as retarded as you are.let fn x y = x + y;;

Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety
>>52067923
I laff'd, but see polyml, multimlton, F#, hasklel, etc.
>>52067967
Makes sense for those languages that were designed for GC, but not C++.
>>52067923
I think that quote would work better with the words reversed.
>Those who would give up essential Saftey, to purchase a little temporary Liberty, deserve neither Liberty nor Safety
>>52067888
Type inference should easily be able to infer a type for a generic/polymorphic function.
For example, in Haskell, the functionplus x y = x + y
is easily inferred to have the typeplus :: Num a => a -> a -> a
>>52067967
None of a functional language's safety comes from its GC. With a sufficiently strong type system, a language can be safer (I'm talking compiles? => correct) than all of those languages without any need for garbage collection.
>>52068083
Sure, if you don't mind losing cyclic data-structures.
>>52067910
nice try but + is a typed operator in ocaml while in lisp + is just a procedure like any other ones.

>implying language of choice is or should be your language of employment
Java is only a language of employment. Nobody informed about anything would choose to use it for personal projects
>>52068097
With sized types, you can retain them, you just won't be able to recurse over them directly (which, of course, is how you keep safety).

Why can't it have a type?

in scheme, you are free to redefine + and the default one accepts all kind of objects (integers, reals (float), ...). in ocaml, + is reserved to integers while +. is reserved to reals. No question that the compiler inferslet fn x y = x + y;;because of the operator +, x and y must be integers in any case.
>>52068208
wait now it says HITLR at the center damnit
>>52068229
>free to redefine +
That's not a problem, you'd just have to redeclare its type at the same time.

That's what the Num type class in Haskell is for.

>>52068264
Java is not required for Android development, you can write apps in C++ just fine.
>>52068264
Many languages support java, including the vastly superior c#(which will run up to 10 times faster on dalvik devices and the same speed +/- for ART capable devices). That costs money though but almost every respectable language can be used on android devices.
In fact java is one of the worst options for android
swastikas are done
what's next lads? how can we meme further?
>>52068300
the language is too big for there to be a quality implementation :^)
i wouldn't actually think about using it for anything but shell script-y shit
>>52068229
You can also redefine + in ocaml, that doesn't change that the type inference works perfectly fine.let (+) x y = x +. y
let f x y = x + y;;
val ( + ) : float -> float -> float = <fun>
val f : float -> float -> float = <fun>
Stop backpedalling and admit you don't have a single clue and that kawa's inference is dogshit.
By the way, even typed racket can infer this kind of type.

it's you who are retarded. an equivalent of scheme's + in ocaml would be something liketype num = Int of int | Float of float
let add (x : num) (y : num) = x + y
you can't infer that.

Is there anything more comfy than settling in with your favourite language, with your favourite beverage, and solving problems using your ingenuity, a bit of math, and some hacks.
I admit, I'm code-monkey tier atm, but I'm perfectly happy just finding the best design principles and making sure my code is readable and maintainable.

they rewrote android in C# (https://github.com/xamarin/XobotOS/) a few years back and then they found that it was a whole order of magnitude faster (https://blog.xamarin.com/android-in-c-sharp/). xamarin compiled apps still run faster (http://magenic.com/Blog/Post/4/Mobile-Development-Platform-Performance) on average and there's a ton more room for improvement when you remember that there's shit like value types, manual memory management, p/invoke, and so on to help you further improve performance
>>52068939
Yes but you don't have to write in Java per se, that's the point.
I'm trying to include my C header file in C++ code, but it's not working out.
I've added theextern "C"thing, I've tried compiling the C code with both gcc and g++ just to test that it actually works, but it still only throws a bunch of "undefined reference to" during compilation.
Any ideas on how to fix it?
>>52069173
not sure if this is the way it works in c++, but did you do extern AND import?
>>52069173
You need to add "-lLIBRARY" to your g++/gcc call. Replace LIBRARY with the name of the library.
>>52069184
That's what I have, not sure what you mean by "import":extern "C"
{
#include "csll.h"
}
>>52069192
It's not a library, it's a local file. Either way, I tried it and it couldn't find anything.
>>52069173
Are the reference errors related to external library or the standard?
>>52069224

You are purposefully telling the compiler "fuck you, compile my shit code that you know is broken" then complaining that your code is broken.
Is anyone willing to look at almost 200 lines of messy C atmega328p code
>>52069311
Why are you passing C files to the C++ compiler.
You probably need extern "C" in your csll.c file too (or compile it with gcc to an object, then use g++ on your c++ files and C objects).
>>52068859
the generic version is inferred when a call is made. the article says// this version works!
let inline twice x = x + x
twice 2.0 |> Console.WriteLine
twice 2 |> Console.WriteLine
Each call to the inline function is replaced by inline code with its own
type inference, thus the compiler effectively converts the above to:
(fun (x:float) -> x + x)(2.0) |> Console.WriteLine
(fun (x:int) -> x + x)(2) |> Console.WriteLine
this is what i have said here >>52067888

It's not broken, it alone compiles fine with g++. It's not the issue, chill out.

Compile your C file into a static C library, and put#ifdef __cplusplus
extern "C" {
#endif
...
#ifdef __cpluspluc
} // extern "C"
#endif
in the header, or scrap all the extern "C" fun and make it compile as valid C++ WITHOUT FPERMISSIVE and do what you were doing.

This might be a retarded question, but why isn't the stack size much larger on 64bit systems?

Not really needed.
Pointer size is doubled, which makes stack frames bigger, but it's incredibly rare the stack size is an issue unless you have unbounded recurstion.

You're compiling both files as C due to the ".c" extension.
If a file contains C++ code, it needs to have a .cpp, .cxx, .cc or .c++ extension. Or you need to use "-x c++" (and then all files must be C++).

You can look a the code, it's basically identical. I suspect mono just doesnt utilize multicore cpus as well. If it were .net it would likely be a closer result,
So /dpt/, if you're doing something and you see that there's already libraries for doing it - do you use one of them or write it yourself? This is assuming you do know how to do it yourself and you won't gain anything knowledge-wise by writing it yourself

C fags love to be misleading. C is a small language. It is not an easy language. By the very nature of being small it's tedious and opens up huge areas of potential bugs.
That doesnt mean you shouldn't learn it. It just means keep in mind that when retards say c is easy, what they actually mean is the syntax is easy to memorize, not that using it to produce anything of value is easy. C is a necessary evil, and an excellent way to understand the computer.

It might be. I have 0 experience with numerical analysis, so I can't comment on that. But by what I'm reading on wikipedia, I don't see what they'd be interpolating exactly.

No.
At least, not something which a) can handle most of the popular web sites and b) isn't just a shallow re-skinning of an existing browser.
Even using existing libraries for HTML, JavaScript, HTTP and SSL, there's still a ton of code needed to glue them all together.

>>52071552
HTTP, SSL, and JavaScript aren't part of an HTML renderer. Some of them may be part of a framework which also includes an HTML renderer (e.g. WebKit includes both an HTML renderer and a JavaScript interpreter, although it doesn't include the networking code).
But if you use a framework which not only includes all of those components but also integrates them, you aren't actually writing a browser, you're just embedding an existing browser, with all of the bugs, defects and limitations of the original. Which largely defeats the point.
>>52071744
F# (pronounced eff sharp) is a strongly typed, multi-paradigm programming language that encompasses functional, imperative, and object-oriented programming techniques. F# is most often used as a cross-platform CLI language, but can also be used to generate JavaScript[4] and GPU[5] code.
F# is developed by the F# Software Foundation,[6] Microsoft and open contributors. An open source, cross-platform compiler for F# is available from the F# Software Foundation.[7] F# is also a fully supported language in Visual Studio[8] and Xamarin Studio.[9] Other tools supporting F# development include Mono, MonoDevelop, SharpDevelop, MBrace and WebSharper.[10]
F# originated from ML and has been influenced by OCaml, C#, Python, Haskell,[2] Scala and Erlang.
>>52071750
>Which largely defeats the point.
The point is to get rid of bloat and botnet. How is that defeating the point?
>>52071744
Language evolution[edit]
F# uses an open development and engineering process. The language evolution process is managed by Don Syme from Microsoft Research as the BDFL for the language design in conjunction with the F# Software Foundation. Earlier versions of the F# language were designed using a closed development process by Microsoft and Microsoft Research.
F# originates from Microsoft Research, Cambridge, and the language was originally designed and implemented by Don Syme.[16] Andrew Kennedy contributed to the design of units of measure.[16] The Visual F# Tools for Visual Studio are developed by Microsoft.[16] The F# Software Foundation develop the F# open source compiler and tools incorporating the open source compiler implementation provided by the Microsoft Visual F# Tools team.[6]

>The point is to get rid of bloat and botnet.
Great portions of the bloat are innate to the rendering engine. Unless you want to rewrite 100 gorillion lines of code, then you aren't going to magically unfuckulate it.

Asynchronous programming[edit]
F# supports asynchronous programming through asynchronous workflows.[23] An asynchronous workflow is defined as a sequence of commands inside an async{ ... }, as in
let asynctask =
async { let req = WebRequest.Create(url)
let! response = req.GetResponseAsync()
use stream = response.GetResponseStream()
use streamreader = new System.IO.StreamReader(stream)
return streamreader.ReadToEnd() }
The let! indicates that the expression on the right (getting the response) should be done asynchronously but the flow should only continue when the result is available. In other words, from the point of view of the code block, it's as if getting the response is a blocking call, whereas from the point of view of the system, the thread won't be blocked and may be used to process other flows while the result needed for this one doesn't become available.
The async block may be invoked using the Async.RunSynchronously function. Multiple async blocks can be executed in parallel using the Async.Parallel function that takes a list of async objects (in the example, asynctask is an async object) and creates another async object to run the tasks in the lists in parallel. The resultant object is invoked using Async.RunSynchronously.[23] Inversion of control in F# follows this pattern.[23]

He -literally- asked about webkit.
>HTTP, SSL, and JavaScript aren't part of an HTML renderer.
I didn't say html renderer, neither did anyone else. I said rendering engine. Which is also called a layout engine. Which absolutely covers html, css and javascript. It doesn't by necessity cover ssl or http but they usually do.
> you aren't actually writing a browser,
Yes you are.
>you're just embedding an existing browser
You're embedding the rendering/layout engine. A browser is a layout engine + a ui of some kind + additional, optional features. By that logic chrome and safari were either not browsers, or the same browser (prior to chrome forking blink). That's retarded.
If you write a program that browses the web you are clearly writing a browser. Whether you wrote the underlying engine is irrelevant. If webkit was a browser it would be offered as a browser. It isn't, because it isn't. It's an engine that powers a browser.

I don't believe we're talking about the same thing. I'm talking about all the useless functionalities of modern browsers.
I'd like a minimalistic browser which just does the bare minimum.

Object programming[edit]
F#, like other CLI languages, can use CLI types and objects through object programming.[20] F# support for object programming in expressions includes:
Dot-notation (e.g., x.Name)
Object expressions (e.g., { new obj() with member x.ToString() = "hello" })
Object construction (e.g., new Form())
Type tests (e.g. x :? string)
Type coercions (e.g., x :?> string)
named arguments (e.g., x.Method(someArgument=1))
Named setters (e.g., new Form(Text="Hello"))
Optional arguments (e.g., x.Method(OptionalArgument=1)
Support for object programming in patterns includes
Type tests (e.g., :? string as s)
Active patterns, which can be defined over object types[22]
F# object type definitions can be class, struct, interface, enum or delegate type definitions, corresponding to the definition forms found in the C#. For example, here is a class with a constructor taking a name and age, and declaring two properties.

Such as?
>>52071861
Why do you keep talking to yourself?
>>52071844
Look, he's an idiot trying to be contrary for contrariness sake.
Make your broswer, yes use webkit. If this is fully intended to be a toy project there are smaller, lighter, easier to use alternatives. If you want something that fits your needs and you will actually use as a browser then do try webkit. Even if you don't succeed, you've learned some stuff hopefully.
>>52071842
yeah, workflows are a nice syntax for monads+
>>52071744
Can i have an if statement inside an if statement in javascript? Or is that wrong because of syntax?

The bit we call the browser is really just the UI that pulls together all these parts. If you're writing a new UI, it's a new browser, even if it uses all the same technology as (say) Chrome. Of course, if your starting point is something like Chromium, that IS just using an existing browser.

I've used it in the past.

what is the difference between unsigned int and normal int?
>>52071886
Yeah, I guess kind of a toy project although hey if it's not too bad I might use it.
Anyways thanks for the advice.

unsigned >= 0
>>52071954
Unsigned uses all bits to express the number and as thus can only be in a positive integer range, signed uses the first bit to detrmine whether the number is negative or positive and as thus can be in negative..0..position range albeit will hold smaller values because the first bit is taken away.
>>52071963
I honestly have no idea how hard webkit is to work with, just the make that clear. Don't necessarily expect it to be easy just because you're doing the "easy part", but good luck
>>52071954
There is no 'normal' int, anon, all integers are created equally and are all beautiful.

/g/ what is wrong with my code, writing a fizz buzz program in javascript<script>
for(var i=0, i<=20, i++){
if(i%3==0){
document.write("Fizz");
if(i%5==0){
document.write("Buzz") ;
} else{ document.write(i)};
}else{ document.write(i);
continue
}
if(i%5==0){ document.write("Buzz")}
else{ document.write(i)}
}
</script>
>>52071954
signed uses negative ranges, unsigned doesn't so it can hold twice as much in its range from 0 to meme.
>>52072007
it keeps giving me a SyntaxError: missing ; after for-loop initializer on line 6

>>52072028
Use a semicolon after the for loop initializer on line 6.
>>52072028
var i - 0; i<-20; i++
The underlying logic is wrong too but I'll let you figure that out.
