Why do C programmers like using short variable names everywhere?

>>59019504
Because historically the C standard only required support for a minimum of like 8 characters in symbol names. People then butchered their codebases in an attempt to be "portable".

FUCKING SATAN'S HAIRY CUNT HOLE
I wouldn't care about matching reference if I knew what caused the difference, but the fact that I can't make them match implies that either I don't truly follow what's going on or I'm making a serious rounding error somewhere.

>>59019504
Because strcpy doesn't really copy strings, it's a shortcut for some short useful sequence of instructions that you pretty much need to "feel" in a sense to know you're using them right. DoWhatIMean is a myth, so calling it cooy_string doesn't help; on the contrary, an unfamiliar name renders the abstractedness of the thing. We can't afford to forget that we fight completely on our computers' terms.

>4 people must cross a bridge. It's dark so you need a lantern, and you've got only one. The people walk at different speeds: one crosses the bridge in 1', the others in 2', 5', and 10'. There can be at most 2 people on the bridge at the same time because it's shaky, and the quicker one must adapt its pace to the slower one to share the lantern, which then has to be brought back by one of them. How much time does it require at least to bring everyone to the other side?

I think the idea is to lazily construct a graph with situations in the nodes and alternatives in the edges, and then A* your way through it, but I can't guarantee that. Anyone?

It uses rotational velocidensity to transpile the BIOS RAM into a compressed bytecode image.

Should you use glib when programming with C or is there some better alternative?

so i have defined this escape sequences:

   BACKSPACE -> \b
   SINGLE_QUOTE_CHARACTER -> \'

i'm trying yo write a regexp that if those escape sequences appears in some text, it throws an warning

would this work?

[^\b\\\']

>>59020158
isn't it always best to just have the fastest guy have the lantern and have him bring everyone over the bridge one by one?

>>59020406
1. Square brackets only match any of the individual characters given, it won't match a multiple character sequence.
2. You've negated the character set given, so effectively what that regex will do is match any character that's not \ or '
3. \b is significant in regex, it represents a word boundary. it also needs to be escaped.

If you're actually trying to match the literal strings \b, \\, and

\'
, you could do:

(\\b|\\\\|\\\')

>>59020524

>>59020615
>for the allowed i had
1. That regex is shit wrong for the same reason as the other
2. Why should one search for the allowed escape sequences anyway? You'll just do nothing when finding one, and if you think about it, if all the other things are neither allowed nor disallowed, what are they?
3. Are you sure the point is the literal escape sequence and not the non-printable character it stands for?

C++ doesn't allow overloading/specializing everything.
Rust doesn't have overloading at all.

By that logic ASM is the perfect language. It's so simple none of the features need any workarounds when you fail to understand them.

Python 3 Here
The guy who was making a tic tac toe shit game
Posted here before but my code was dirty as fuck so I cleaned it but I still encounter the same problem, please help.
So i have this function

check3()

which like the name implies it checks for a line of three X's or O's

for a in listcombi:
        print(sum(a))
        if sum(a) == 3:
            P1W = True
            gameend = True
        elif sum(a) == -3:
            P2W = True
            gameend = True
        else:
            pass

I have a print(sum(a)) there because I want to know if this is working correctly and it does, when there is a line of 3 X's it prints 3 and of O's -3, and if i make it to print gameend it comes out as True, everything is good as it is now, but I have a function which ask the input for the user and if gameend = True this function should stop

def askinput(P,N):
    check3()
    if gameend:
        return winner()
    else:
        #Everything

So the function runs 9 times, 5 times for Player 1 and 4 Times for Player 2, but when gameend = True, the function keeps running and doesn't return

winner()

What the hell is happening ?
I need help
By the way winner() is defined before check3() is defined

LLVM is only the backend. rustc first has to desugar Rust code and optimise in all the ways trait magic was promised to enable. So far it does not do that to a satisfying degree. If you hand LLVM some high level abstracted code, don't expect it to produce very fast machine code.

Are you even using a loop somewhere in there? It sounds like you're doing it recursively or misunderstanding what return does. Poast whole code, I can't reason on partial information.

Yes, but in rust the cause is a bit different. Rust fell hard for the FP meme and converting semi-FP code to something fast is a decent hurdle. The other problem is that good, fast algorithms are often invalid Rust code, because the borrow checker can't reason about them. The thing is fucking too primitive.

So, theoretically, Rust can become a really great language. Completely memory safe, high level, but optimised down to very efficient code thanks to the type system. In practice the compiler is shit and needs at least 5 more years to become viable.

>tfw go doesn't even have any gtk/Qt bindings
How am I supposed to write small UI applications now?
Either: dive straight into Rust autism
or use python or Java

I want none of those obsolete C or C++ trash, might as well use ALGOL 60

>>59021072
Use ALGOL 60.

>>59020676
think about real programs

if the program has an invalid escape sequence, the compiler should throw something like:

Error: invalid escape sequence <%s>

the point is if you find escape sequences that are not allowed you inform the user with an error.

its like a error detection regex

>>59021072
Ada has bindings and is from the Algol lineage

>>59021046

Yes and no, Rust isn't all very far on the FP spectrum. They have lambdas just like C++, and generic algorithms like map that take lambads, just like C++. But that part isn't hard at all to optimize.
Things like encouraging a recursive style and immutable data structures would have been bad, but Rust doesn't have that.

>The other problem is that good, fast algorithms are often invalid Rust code, because the borrow checker can't reason about them. The thing is fucking too primitive.
Very true.

>So, theoretically, Rust can become a really great language. Completely memory safe, high level, but optimised down to very efficient code thanks to the type system. In practice the compiler is shit and needs at least 5 more years to become viable.
It certainly can and needs to improve, especially if you're going to write naive code and expect it to be fast.

But at the end of the day it's still a systems language, if you need to optimize Rust will happily let you go all the way down to assembler, and you'll have no excuses in the benchmarks.

>>59021121
>if you need to optimize Rust will happily let you go all the way down to assembler,

>error: inline assembly is not stable enough for use and is subject to change (see issue #29722)
Rust is a meme until all the features necessary for systems programming become available.

Go is intuitive unlike Java or C#. It's a good garbage collected language.

But I like Rust better anyways.

>>59020960
>>writing servers
>implying that's the only thing you can do
when will this meme end, that Go is only useful for web stuff? have you ever looked at a list of projects that use Go? I bet you are already running at least 1 Go program without knowing...

is /dpt/ really this ignorant? do you retards do it on purpose or something?

>>59021138
Rust is a young language.
Limiting yourself to stable is like using ANSI C and complaining it doesn't have a memory model with Atomic weapons.

I am creating a wildlife cam for my dad with an IR sensor and a webcam.

However, I can't get the raspberry pi I'm using to record faster than 6fps, which isn't too much of a bother, but the video still plays at 30fps.
How would I manually set the playing speed?

I'm using Python+OpenCV2.

>>59021224
GNU C isn't really as featureful as a NEET thinks. Grow up and get a job. I don't mean to disrespect GNU but GNU C is far from perfect. Rust is 2 y/o and it already competes with C++.
If you don't count the attendance of libraries C++ or Java has, Rust is already a better language ootb as suggested in >>59020689


>hurr durr no tooling etc
When C came out, there was no tooling available as well. Then UNIX was born.

Rust is not (currently) better than C in terms of libraries and performance. But there are already many interesting rust projects found on github.
Heck, Rust even has Redox OS, an OS with a microkernel architecture that HURD wanted so hard to be.

I'm not saying you should tell your boss to translate your project to rust, I'm saying that you should ditch C, it is living in it's borrowed time. Once the LLVM backend of Rust gets matured it will be as fast as C.

[irrelevant] Cargo's package managing system is amazing. No more fucking yourself in the ass with makefiles and waiting thousands of years to compile.

Novice here to put it kindly. I'm doing a paper, rock, scissors game for java. Think I got the basic game working as intended. The thing is that I need to have the program initiating new rounds until either the computer or the player wins three games total.

I suppose I need to but a while loop. I improvised as I went along and now I have no idea how to do this.

Should i put it in here?

public static void main( String [] args) {

Random random = new Random();
Scanner scanner = new Scanner( System.in);
String computerChoice;
String userChoice;
String winner;

showMenu();
computerChoice = generateComputerChoice( random );
userChoice = getUserChoice( scanner );
winner = chooseWinner( computerChoice, userChoice);

System.out.println("You chose " + userChoice + "\nComputer chose " + computerChoice );
System.out.println(chooseWinner(computerChoice, userChoice));

I was thinking something in the lines of

while(computerChoice<3 || userChoice<3){

I mostly meant the infrastructure(that I called convoluted). Compiling 40k SLOC(most of them are generated from designers) for 2 minutes straight is a disgrace. Java itself has optimizations for number crunching(that's why it's often fast in certain math benchmarks) but once you start dealing with OBJECTS and especially collections, everything goes to trash. C# has true arrays and can allocate objects on stack, Java defaults to heap and everything is referenced.

java also has "true" array, although not "true" multidimensional arrays. are you maybe confusing the two?
neither java nor c# specify whether they allocate objects on the stack or the heap, anon.
while c# structs can get allocated on the stack more easily, they aren't always allocated on the stack.
in addition to this, structs aren't common at all.
the hotspot jvm has escape analysis, so it may also allocate objects on the stack!

>is an int[] an array of references? primitive types are value types, anon.
I just checked and for arrays primitive types are indeed not autoboxed. Obviously doesn't work for collections. Meanwhile in C# you can allocate an array of structs on stack, or even do manual memory management with pointer arithmetic if you want. Java is faster in primitive cases, C# is faster in just about everything else.

>>59022331
Rust is more like a C++ replacement. Golang is a replacement for nothing.

>>59022599
for structs to get allocated on the stack, they need to be sufficiently small.
for both c# and java, you can optimize for cache efficiency by grouping primitive types in multiple arrays.
c# allows you to get rid of some levels of such grouping (for instance by having an array of small structs), but there really isn't that much of a giant difference.
point is, you can write cache efficient code in both languages.

you're right about c# allowing unsafe code and that theoretically allowing you to write more efficient code, this is however a trade off in regards to sandboxing.

>>59022598
no, anon, i was not implying that, haha

>>59022668
>you can write cache efficient code in both languages
>All of the objects have massive amounts of padding and other shit
Good job wasting all of the space on your cache lines

>>59022605
yes, boxing for primitives in generic types sucks and harms efficiency, just like the entire way java generics are implemented.
i thought that was a given, though, and not relevant to the debate.

You can force that with a keyword stackalloc. C# is simply faster when dealing with data structures(let's be honest, it's 99% of the time), too bad there's not many benchmarks to show.

>>59022737
>You can force that with a keyword stackalloc.
didn't know that, thanks, although it requires unsafe, and if we're talking about unsafe code, c# will end up faster either way because it isn't restricted by the same sandbox restrictions as java.
>C# is simply faster when dealing with data structures(let's be honest, it's 99% of the time)
i agree that c# is potentially faster in the practical case for many reasons (e.g. i don't disagree with your point about the java eco system either), just saying that java (ergo the optimum in the best implementation) isn't "slower" than c# per se.
of course you need to disregard the mess that is generics and a large part of the eco system for that.

>>59022737
Anyway, speed isn't even the main advantage of C#. I got distracted too much already.

>>59022800
>C has evolved since then.
By including accidental addons like macros

>>59022861
i wish both the state of the art java and c# gc would optimize more for latency and less for throughput by default. you can probably tweak both, though.
it's interesting to see that the main dude behind the hotspot gc is now working on the go gc and took an entirely different focus.

Started work on a browser extension that sorts a 4chan thread according to replies. The indented posts you see in the screenshot are replies to the parent post above it. The numbers to the left of the post show the number of direct replies each post has, and the number of nested replies there are total, respectively.

Clicking on a reply expands that tree so you can read deeper comments.

It's a super rough proof of concept, but would this actually make a thread easier to read?

I can see you type, upload images, etc. in realtime and vice versa.

the runtime knows which code paths, allocations etc. are most common, so it is theoretically able to cache things and spend excessive ressources on optimizing the most common code paths.
i'm not sure about the statement that anon made (that java could do better than c) but at least in theory the runtime's able to optimize more efficiently than a compiler, simply because it's provided with a lot more information.
