What dialect of C is the Linux kernel programmed in?
Why does dwm not use the stdint.h library?
Why do some projects not use the stdint.h library?
Isn't int16_t much better than just int because it is more specific?

>Write for programmer first, for compiler second. Your co-worker will not be easily convinced, so I would prove empirically that better organized code is actually faster. I would pick one of his worst examples, rewrite them in a better way, and then make sure that your code is faster. Cherry-pick if you must. Then run it a few million times, profile and show him. That ought to teach him well.
I find it suspicious that advocates of object-oriented programming find it necessary to deceive critics to convince them of its superiority, or that this kind of behavior is acceptable at all in an academic and/or professional environment.

Plan9 C. Nice, small libraries with pleasingly simple names (dprintf -> print), automatic inclusion for linking, simple conventions, best toolchain, a no technical debt environment, etc. The only thing is that it didn't take off, sadly.

Not true sorry. It's still the nicest environment to do system programming in C tho. Also see http://plan9.bell-labs.com/sys/doc/comp.html
Novice here, I decided to try and program the game Bang! in Java.
For those who don't know the game: it's a card game for 3-8 players, each has a role card (determines victory conditions), a character card (determines special power), and a bunch of playable cards. At the beginning of your turn you pick up 2 cards, then you can play blue cards for equipment, green cards for temporary equipment and orange cards for immediate actions. There are many different types of cards for each of these 3 categories.
Now here's my (main) problem: how should I go about implementing the "character cards" functionality?
There are like 80 different cards of this type and each has a different power that can influence a different aspect of the game. For example, one card could let you pick 3 cards at the beginning of your turn instead of the usual 2, another could let you shoot other players with cards other than the usual "Bang!" card, another still could let you regain 2 HP instead of 1 upon using a "Beer" card, etc.
I have this feeling I should use inheritance and make each character card its own class, but then how would I ensure that the program applied the special ability regardless of which aspect of play it modifies? Do I just have to have a check at any action? Or is there a more elegant way?

That'd be at least 81 classes. I've played the game, you could instead use scripts to load in the stats and abilities and have the abilities be flags that are not dissimilar from the equipment cards. Like "heal_amount = 2" "ignore_range = true" etc.

So I have a nested loop in .net, and I want to refer to the indexes in the code running in the loop without having to type a long list of x = i, y= j, etc. Ideally I would want to have an array and use i(0) as the first index, i(1) as the next, etc, but it won't let me do that. I could use a dictionary and add all the index variables to it but it seems slow.
Is it just me or has there been a sharp decrease in activity of these threads?
>>54908533
>I want to refer to the indexes in the code running in the loop without having to type a long list of x = i, y= j, etc.
So.. just refer to them using i, j?

>Why does dwm not use the stdint.h library?
Doesn't need exact width types. The C standard library also does not use stdint types for most things.
>Why do some projects not use the stdint.h library?
See above.
>Isn't int16_t much better than just int because it is more specific?
No. If you don't need an integer to be exactly a specific size, don't use fixed width types. They aren't even defined on all platforms (in particular, the ones that use 9-bit bytes). As a general rule of thumb, you should firstly always use the type of any function you are using that you haven't written. Most C functions use int to return status codes, and that's perfectly fine. The size_t and ssize_t types are often used with regards to strings/arrays, because the maximum sizes for these often vary based on the platform. I'd rather not use an int64_t to store my string length if I'm on a 32-bit platform, and I'd rather not be gimped by the restrictions of a 32-bit platform on a 64-bit platform, so when storing the lengths of these structures, and often when making indices to offset them, a size_t or ssize_t is preferred.
>>54908657
>Because it's a lot of nested loops

>>54909119
>in particular, the ones that use 9-bit bytes
1. Which platforms?
2. Does anyone care about them?
>>54909141
1. Unisys/Univac machines. Some are still in use today. Also, some old IBM and DEC machines.
2. Not really, although I honestly think when writing C code, it is best to make the least amount of assumptions possible about the target platform. If you know something needs to be 32 bits, then by all means, use uint32_t or int32_t. Otherwise, int is fine... unless it NEEDS to be at least 32 bits, in which case int_least32_t is your best bet. And yes, I happen to have multiple devices in my room where int is 16 bits, rather than 32.

Hiding complexity is actually best thing you can do to avoid fuckups. Stupid, unskilled and mediocre pogrammers (including yourself) don't have to tackle all shit that's behind the functionality, so chance that they screw something up decreases. Also saves time for everyone.

You're doing OOP wrong.
Not the guy you're responding to, but OOP's approach to complexity management is fine. It's modularization, i.e. correctly handling the complexity and preventing future maintainers from having to deal with that complexity unless necessary.
>>54910721
>modularisation doesn't happen in any other paradigm

That's right. OOP is the GOATest.
>>54910677

>>54910748
Why not?
>>54910677
>and there is nothing more pointless than making accesors and mutators if all that they do is returning or setting private variable
yes, but if you end up deciding that you want to do more than just "returning or setting private variables" the interface stays the same.
The point of encapsulation is about making interfaces that abstract away the implementation so the end result is the same between versions. Likewise, you should always minimize mutability of your variables, your variables should be set by the client at construction, after that if you're using setters your implementation probably needs refactoring.
Accessors are open game though.
>>54909984
>What irc client is that ?

>>54910764
C# gets this right. Want a mutable property?{ get; set; }

>just make the fucking variables public

>>54910782
Now say you've published that class as a library, people are depending on it, but you notice 64 bits isn't enough precision for some applications, so you decide to use gnu gmp instead.

>>54910835

This looks like ES6 javascript but it's not. What is this?
>>54910915
You can add logic to the { get; set; } version without changing the interface. The first version is a field rather than a property, and reflection treats them differently (generated IL may also be different, but that's just me speculating), so changing from field to property is a change in the interface.
>>54910933
D
. also does UCFS so it pipes the thing before it into the first parameter of the call, i.e
5.someFunction(3) = someFunction(5, 3) (unless there's already a member for that)

1) HTML5/JS is a powerful platform that delivers applications to billions of people around the world, it runs on billions of devices.
2) Javascript is a descendant of Scheme and Self, so it is pretty cool language, especially if you forgive it its small defects. Solving the same problem in javascript seems to require 3-4x less code and 2-3x less dev time than solving it in C/C++/Java.
3) Fastest compilers/runtimes ever written for a dynamic languages were written for JS: V8, Chakra, Spidermonkey, Javascriptcore. JS is the fastest dynamic functional language in the world.
Programs written in JS tend to have 3-4x less code than equivalent C++ programs due to higher order functions and dynamism. Seriously, if you value your time you should use a dynamic functional language at least for prototypes.

DESU while JS isn't my favorite language, it's not the worst thing ever, particularly if it's the modern variant.
What I hate is HTML + CSS being a slow, clunky hack that isn't suited at all for most of what it's used for. Without optimization HTML + CSS is one of the most inefficient ways to construct a UI out there, optimizing it isn't a cakewalk, and even the most optimized HTML + CSS will be destroyed by any decent native UI toolkit (barring Windows, anyway. MFC, etc sucks ass).
If JSers could come up with a replacement for HTML + CSS that's specifically designed for creating applications (as opposed to presenting static documents) and use it instead of chromium wrapper crap, that'd be amazing, but they won't do that because web devs almost never care about efficiency. As long as it runs on their brand new quad core laptop with 16GB of RAM it's good, everyone else be damned.

>NaN
NaN is still a numeric type, despite the fact it actually stands for Not-A-Number.
NaN just means the specific value cannot be represented within the limitations of the numeric type (although that could be said for all numbers that have to be rounded to fit, but NaN is a special case).
A specific NaN is not considered equal to another NaN because they may be different values. However, NaN is still a number type, just like 2718 or 3141
>==
double equals is for 'truthy' and 'falsy' comparisons and should very rarely if ever, be used.

no shit, the default sort for arrays in Javascript is an alphabetical search

I thought about this, and that's why I have created my own V8-driven SDL2 application platform. It doesn't give you anything but canvas-like framebuffer though.
V8 is just a C++ program, you are free to create whatever you want with it.
There are also other projects, see react native and node.js GUI bindings.

I'm aware of React and its various flavors of native (mac, iOS, etc). I have no plans of using them personally because when I write JS it's going to be two lines on an otherwise static site.
It existing isn't enough, though. While React takeup seems to be high, everyone uses it to render to HTML browserside which defeats the purpose. The userbases of the various react native projects is tiny in comparison.
I wrote a set of Node.JS scripts to wrangle my BIG DATA: several gigabytes of search engine queries.

Your count function should be in your prime() function, it only goes up from the 2 it starts at because you don't increment count within your prime function. Does that make sense? Please ask a question if it doesn't, I tried to explain it clearly.
>>54911431
No you can't do math, j is represented as 1111 1111 1111 1111 (if int is 16 bit) which is definitely greater than 0000 0000 0000 0001 (representation of i).

>>54911813
This is just an html file
>>54911437
>>54911828
> it only goes up from the 2 it starts at
I meant it only increments the count once from 2 to 3 within your prime_2 function. Because you only go through the prime_2() function once, so count only goes up by one.

Chrome gave me an unexpected syntax error after running it.
>>54910952
neat
Javascript ES6 also uses lambdas in the same syntax.
I'd never heard of UFCS but it seems neat. Javascript programmers tend to do similar stuff in order to do functional programming or for some design patterns they use. Personally I would rather just have partial application, like Haskell does.

I don't really understand what the template invocation is doing but that aside D looks like a much nicer language to program in than I previously thought. Thanks for the info!
>>54911047
Well, that's almost the same assequence+StateT a m ()
>>54911437
Oh, crap, your stuff is more complicated than I thought at first. >>54911867 again. I think it has something to do with the recursive call you got going on with returning prime_2(n-1). I might have just confused you. I would restructure your recursive call, because without going through the debugging myself it's hard to picture what's going on in the stack in my head at least.
>>54911185
Yes.

That is the purpose.

"""it's very easy to write bad Javascript."""
>>54912066
Oh, are functions in general not first class citizens in D? They are in Javascript, so it's fairly common to pass a lambda as a function argument like you did there.

A large number of people out there only scratch the surface of javascript and fall back on frameworks, coffeescript, and libraries like jquery to avoid having to actually learn the language.

>A large number of people out there only scratch the surface of javascript and fall back on frameworks, coffeescript, and libraries like jquery to avoid having to actually learn the language.
These people should be purged in a great cleansing.

They are but it's faster given templates are compile time
>>54912182
I see, that does actually sound pretty cool.
>>54911437
Does your code need to be recursive for homework or something? I feel like this version makes more sense to me and correctly gets 10 steps?def prime(n):
for x in range(2,n):
if n%x==0:
return "not prime"
return "prime"
def prime_2(n):
count=0
hip = str(n)+ " -1 = " + str(int(n-1))
global x
while prime(n) == "not prime":
count+=1
print hip + " " + "not prime"
n=n-1
print count
print " "
return "number " + str(n) + " is prime found in " +str(count) + " steps"
print(prime_2(45687))
>>54911437
Also, I think the biggest problem with your counting in the recursive function is you reset count to be 2 every time you call the recursive function.

that basically narrows it down to Java, C#, D, etc. (in C++ it would bepublic:)

QJsonObject data;
QNetworkAccessManager network;

QUrl jsonURL = QUrl(url);
request.setUrl(jsonURL);

}
QString strData = (QString)reply->readAll();
QJsonDocument jsonTest = QJsonDocument::fromJson(strData.toUtf8());
}
So I am just trying make a Qt application that just downloads 4chan images from a thread. I'm confused on getting the JSON for the thread. The url that is being used is https://a.4cdn.org/g/thread/51971506.json. I printed it out to be safe. when I try to print out the size/length of of strData and jsonTest, I get 0.
If the Qt built in library is not good enough, what are some other libraries I should use instead?

I don't write much Qt but it looks like your code isn't asynchronous whilenetwork.get()is. reply is going to be null when your if statement runs, because the if statement runs immediately instead of waiting for a server response.
I don't know how you do asynchronous networking properly with C++/Qt, but with Objective-C/Cocoa we usually use completion blocks (known as closures in other languages).
>>54912948
That's because you didn't have it print when it reaches a non-prime number.
You can add it outside the while loop that I had. The part where it prints is inside the loop, when it hits the prime number, it exits the loop. >while prime(n)
Hope that helps.def prime(n):
for x in range(2,n):
if n%x==0:
return False #not prime
return True #prime
def prime_2(n):
oldn=n
count=0
hip = str(n)+ " -1 = " + str(int(n-1))
