>>54464139
I don't understand what you're asking for. What does this have to do with ARM? ARM is useful for low power applications, which as far as servers go actually save costs on power per watt. So as far as that goes, some companies are willing to go with ARM for servers because it helps reduce operating costs while getting the same amount of computation done.

Why make stacks an object when they are a datastructure inherent to the CPU? You are over complicating them. Arrays are just memory managed stacks.
If you need to run methods on an array, why not copy an array and create an object's attribute out of it, then run whatever method you need to?
>>54464331
"Better" is vaguely defined. I use both C# and C++ heavily, and I find that each is better than the other in some ways, but I can't say that one is wholely better than the other.

Also, you can't tighten a bolt with a hammer, so the hammer uses change EVERY FUCKING BOLT to be a nail instead, because it jest werks.
I love C++.
But as far as I see it, C# or Java are all in all a better bet. Not because they are faster than C++, but because when you add up their qualities, they end up being more productive, needing less training, and having more complete standard libraries than C++. And as for most of programs, their speed differences (in one way or another) will be negligible...
>>54464637

>>54464637
not to mention that you can use the time saved with productivity improvements to optimise your Java/C# code. It's not that uncommon to hear of C++ codebases being rewritten in C#/Java being orders of magnitude faster because there was much more time available for optimisation and many easy ways to optimise.

C# is sorely missing a good cross platform UI library. Java has a big advantage here. Even though Swing/JavaFX are shit, at least they work and are well supported.

I don't care for the forced indentation and dynamic typing, personally.
I'm sure Python is fine, but I have no need to force myself to use it.
>>54464620
error prone. just last week I wrote a nested loop like thisfor (int i=0; i<sizeof(array); i++)
{
for(i=0; i<sizeoff(array2); i++) {}
}
I've written loops thousands of times but I still make this mistake. probably because the habit is so ingrained I don't pay attention to the names anymore. call me a bad programer but I like writingfor i in array
more thanfor (int i=0;i<sizeof(array);i++)
not least of which I now dont have an extranious "i" in scope
>>54464693

But some of the syntax is special snowflake and it makes me not want to use it.

word. I usually do something likefor person in house.people
for body_part in person.parts
so name collisions are still possible but less likely
>>54464637
I agree for the most part, and personally find C# to be very near ideal as far as aesthetics and philosophy for a language of its sort. However, your use of the word "negligible" here may be a bit of a stretch. I'm all for the use of C# for a reasonable range of applications, but I also think it's important that the performance difference not be understated. I should also mention that while C#/C++ is apples to oranges, C#/Java is apples to apples, and it's much safer to say that C# is better on the whole. Not a huge difference, but enough that I would take C# over Java without hesitation any day, provided it's an option.
>>54464670
You mean ruby.
>>54464686
Massive improvements on that front soon, I would hope.
At the moment, you can use Xamarin to target all mobile and GTK# to target all desktops.
UWP is a write-once GUI that you target device families (tablet, mobile, desktop, console) and the GUI automagically modifies itself to better suit the platform. Windows systems and PS4 only for now, IIRC.
After the recent freeness of Xamarin, I'd imagine the next big thing would be the cross-platform desktop GUI.

>If you need to run methods on an array, why not copy an array and create an object's attribute out of it, then run whatever method you need to?
Java arrays are pretty low level and the little OOP stuff they have actually very simplifies things. I can't really picture what you propose, but it seems way more complicated than what Java is doing now.
>>54464738
At first I was annoyed as hell that I had to refresh my XML knowledge just to do the most basic shit in android.
Eventually though, it grows on you, especially the fact that the GUI stuff is fully segregated from the logic code, as it fucking should be.
You can make horrible hybrid classes that directly access the GUI, but you'll be limited eventually, so it forces people to use the segregated XML.
That said, the inconsistencies between camel case, pascal case and snake case never cease to trigger my autism.
>>54464754
This is how I do it in C# as well.

I fucking hate the way you have to inflate the xml layouts, and even worse, the way you are meant to access elements by id. It could hardly be more verbose. They couldn't just do it like WPF does it, because that would be too much work for them i guess. It's incredibly retarded sometimes.
That said, it's pretty fast, mature, fully featured and well supported. That's good enough for any UI framework.

I'm fucking around with playing cards today. I have this method in my Card class, that is supposed to compare two cards are return true if this < the other card. btw, to keep it simple, I have the face value and suit represented as integers./**
* Compares this card against another card.
* @param that - the other card
* @return true if this < that, false otherwise
*/
public boolean less(Card that) {
if( this.suit == that.getSuit() ){
if( this.faceValue < that.getValue() ){
return true;
}
} else if( this.suit < that.getSuit() ){
if( this.faceValue <= that.getValue() ){
return true;
}
}
return false;

I may have been wigged out on lack of sleep while watching //build/, I swear they mentioned it in a universal app demo.
Consider it false unless I find actual proof, I suppose. Certainly compatible with Xbone though.
What's neat is a developer can convert a full application to a UWP fairly easily.
They ran The Witcher 3 through the converter and ran it natively in a Store App with no performance hit.

is this Java? The idiomatic way to do so is to implement Comparable:class Card implements Comparable<Card>
Then you get to plug into a lot of standard functions for free. For example, Collections.sort(cards) will sort a list of cards using your custom logic.

Java arrays are not that different from C arrays, you just can't do pointer arithmetic, get runtime bounds checking and several useful methods, like length. they're objects probably because every reference variable that's always allocated on the heap is an object in Java

These are the bits you comment. Otherwise you should strive to make code readable. Unnecessary comments bloat the codebase, can themselves be confusing and go out of date or become misleading very easily. I've seen this happen far too often in code bases.
Seeing stuff like//update the name textbox
window.nameTextBox = person.name;
stuff drives me nuts. It's clearer to just read the code that to read the comment to understand what's happening. Unless you're doing something unusual this is generally the case.

bullshit, especially for java arrays from which you can't inherit etc. considering that object variables in java are just hidden self dereferencing pointers, an array of primitives in Java isn't much more complex than a pointer to a struct with an array and several function pointers
C# :
- Xamarin
=> Android, iOS, Windows Phone, W10 and OSX apps
- Unity engine
- .NET apps
- .NET / Mono / CoreCLR web apps
tell me why you don't use it already
>>54466718
because mono is shit and I dont want to program on phone apps
>>54466718
Because F# is better

job applications for an entry level rails position. kill me
>>54466339
not nearly as simple as in Rust, for example
im not saying it's bad for interpreters, but out of all the things C can be used for that's not really one where it does much better than any other language
>>54466338
yeah I agree. the only comments I ever leave in other than those are comments for generating documentation

Basically Xamarin cherry picked benchmarks as "proof"
>>54463714
What's the fastest way to turn a website into an Android app? I'm using Xamarin. Someone on here suggested WebView yesterday. I have 6 hours.
>>54466911
fuck, can't find it now. There's a blog article that compared a bunch of crossplatform frameworks and did benchmarks.
Mono was faster than Java on a bunch of shit. Though that might not still be that case.
>>54466945
Wasn't an article by Xamarin. You're thinking of when Xamarin ported Android to C# and found it ran faster than the original.
>>54466972
WebView. Takes 2 minutes. Create app with a webview inside. Make it load your website. Done.
>>54463714
Fuck everything. I'm just fapping to that.

You just searched on Google "Assembly object oriented" and didn't even read what you just shared. I see you haven't done a lick of Assembly language in your life, either, you aren't even slightly read on it. The article that you posted specifically covers replicating what happens when you compile an object oriented program, the result is not even close to object oriented anything. That's like writing some 2,000 lines in C utilizing nothing but gotos, stacks and booleans and saying that it's object oriented because it returns the same result.
>an array of primitives in Java isn't much more complex than a pointer to a struct with an array and several function pointers
Functions, arrays and structs are all extremely complex to replicate in low-level systems.
Please for the love of god stop talking about something you know nothing about.
>>54467008
Okay. I don't really know C# beyond the basics. I hope I can pull this off.
How do I get the website? Can I just use wget in powershell? I don't know if I have bash installed in this laptop.
How do I load the app onto the Android phone?
>>54467088
you just dothis.myWebView.url = "http://muhsite.org"

Dude, you need to read this stuff up. Just follow the tutorials on the xamarin website for getting started.

He thinks pointers are relevant to low-level systems, and bought the "C is low level" meme. Stop replying to him.
Can i write android apps in C or does everything have to be java?
>>54467148
You would have to deal with JNI and other shit to interface java with C
working on a progam that given calculates all possible combinations of n squares that make up a number m.
f(3, 14) for example should output
1,2,3
so far so good, just code it likevoid partitions(string prefix, int max, int depth) {
if (depth <= 0) {
double intPart;
if (modf(sqrt(max), &intPart) == 0.0) {
cout << prefix << (int)intPart << endl;
max = intPart;
}
return;
}
for (int i = 0; i*i <= max; ++i) {
partitions((prefix + std::to_string(i) + ", "), max - i*i, depth - 1);
}
}
The probelm ofcourse is catching dublicates. currently the code would output1, 2, 3
1, 3, 2
2, 1, 3
2, 3, 1
3, 1, 2
3, 2, 1
that's very messy. Does anyone have ideas on how to prevent that?
The only thing I can think of is putting all n numbers into a vector, then comparing the current numbers with every n-tupel in the vector and only outputing the values if there was no match. I'm sure there's a more elegant solution though.
>>54467262
naive way, like you're saying
sort numbers -> into pair/tuple -> into vector or set
>>54467071
>The article that you posted specifically covers replicating what happens when you compile an object oriented program
which was the fucking point. you said objects in OO languages are as far from low level as you can get because their representations require juggling thousands and thousands of operands etc
>not even close to object oriented anything.
just like array objects in java
>Functions, arrays and structs are all extremely complex to replicate in low-level systems.
which again doesn't have anything to do with anything
>>54463714
Fuck off this programming fag meme.
>>54464886
There's a fast hack if you want.
Assuming your values are all ints and they're something sensible (1,2,3,4...) then you can set a value...just call it 'cardValue' which is the following://in the constructor
cardValue = that.getSuit() << 4 || that.getValue();
//later in the class
public boolean less(Card that)
{
return this.cardValue < that.cardValue;
}
What it does is it gives a unique value to each card, in ascending order of the value of the card. It's just binary arithmetic. Higher suits are larger numbers, and within suits the value of the card is simply compared.
I just blew an interview with google. I didnt expect to get the job but it still feels like shit that I couldn't handle their easy questions
Is using geopt a good practice or should I rather parse arguments on my own?
>>54467729
What kind of stuff did they ask you?
Personally, I wouldn't want to work at google.
They're in a world of their own when it comes to hiring and despite only wanting the best and brightest, they have most of them doing menial grunt computer janitor work because they can't all be project leads, after all.
>>54465506
Are you just fuckin' around or does this actually cause a stack overflow? I don't see any recursion or the typical shit that causes those.
Also neat, multiple return types in java now. Still not using it.
>>54467681
holy shit. that is ...magic. you just blew this junior SE student's mind.
thanks!
>>54467774
The dumbest question I fucked up was "you are given a string and a list of characters, return true if any of the charcters in the list are in the string"
I started going at it considering the fasted route and then the guy then implied I didn't have to optimize it. I was like "okay" and brute-forced it and then he asked me if there was a better way to do it and I couldn't think of one
honestly that guy was kind of an ass looking back at it, but I should have just quicksorted the character list and then quick-searched each character in the string
If I want to replace all occurrences of "dogs" except when dog is located between 2 asterisk i.e **dogs** is it possible to do in regex?
So regexReplace("dogs", "cats") on
>dogs eat dogs at **dogs** house
I should get
>cats eat cats at **dogs** house
>>54465506
since when does java have vars and tuples?
I'm using Python's requests module and i'm writing a script that basically monitors a website for certain changes.
But as someone who is using free dormitory internet (with limited bandwidth), i am concerned about a script like that eating up all of my bandwidth.
If i make one HTTP GET request, then the response is basically the whole HTML document of the website, right? How big is that normally, like let's say http://4chan/g ?
I'm guessing it's somewhere in the range of 100KB, so i probably wouldn't want to download that every 5 seconds (about 3GB within 1 day), but more like every 5 minutes (like 50MB within 1 day)?
I checked if the HTTP Response Header includes a "last-modified" tag, but for some reason it doesnt (not the /g/ example but the actual website im trying for). maybe because it's a dynamically created website.
>>54467957
It doesn't
>>54467882
its not Java and its not really multiple return types
local functions basically create an anonymous class -- similar tovar t = new { sum = 0, count = 42 };
t.sum == 0 && t.count == 42
>>54467957
>>54467882
it's c#
>>54467931
I would have replied with a simple naive nested loop function.
What else did they ask?
>>54467681
>>54467898
I just realized the first line was totally wrong, but you should have got the sense of it at least. it should becardValue = this.getSuit() << 4 | this.getValue();
>>54467947
>dogs(?=([^*]))
that'll match only dogs that isn't surrounded by 1 pair of asterisks which works for your use case, but might not work if you want *dogs* to be different from **dogs** (uses positive lookahead, so check to see if your regex implementation supports it)
>>54467931
>brute-forced
>>54467996
>nested loop
jesus christ, how the fuck can you think of anything else than a lookup table? this is school-level stuff
>>54468095
it's on the spot
if you were paying me to do this, I would give you a lookup table after thinking about it
>>54468095
>lookup table
wouldn't I have to use a nested loop to iterate and compare through every table entry?
>>54468125
on the spot? it takes you like half a second to think lookup table and about 6 lines of code to implement it!
>>54468049
Thanks
I actually forgot something that might complicate it a bit, ** these dogs should also not match**
>>54467947
Asking how to do something "in regex" is sort of like asking how to do it "in a script". You need to specify the language for it to be useful.
If you don't know which regex dialect you use, just specify which language/library/tool it is. (Java uses PCRE, sed uses POSIX BRE, and people working with tools know this).
>>54468170
What about:** dogs ** dogs ** dogs **
>>54467993
m$ java then. Close enough.

I don't know about working at google. Faggots look down upon you for going to work in business casual. Fuckers make t-shirts and shitty jeans mandatory.
Anyways decided to implement the google challenge in a silly way just for fun. Rate my code /dpt/#include <stdio.h>
#include <memory.h>
#include <stdbool.h>
bool comparison[256];
bool blank[256];
bool contained_q(char * list, char * string) {
memcpy(&comparison,&blank,256*(sizeof(bool)));
for(int i = 0; list[i] != 0; i++)
comparison[list[i]]=true;
for(int i = 0; string[i] != 0; i++)
if(comparison[string[i]])
return true;
return false;
}
int main() {
for(int i = 0; i < 256; i++)
blank[i] = false;
printf("(%s,%s,%i)\n","aeiou","hello",contained_q("aeiou","hello"));
printf("(%s,%s,%i)\n","aeiou","why",contained_q("aeiou","why"));
}

i'm thinking of how a lookup table would work, I'd literally have to create an array and pad it out with just the ascii values I'm looking for and 0's for everything else.
like *lookup = { 0, 0 , 0, .... 'W' } if i wanted to catch a W it would have to be the 87th item in the array
Am I doing it incorrectly?
C baby here,I have a string like "500+600", what's the best way to break them to two integers and shove them in into an array of strings?
I'm having a lot more trouble with this than I expected. I'm looping through grabbing each char putting it into an array until I hit an operation symbol, then trying to send that array (the first number basically) into the string array, but I have no idea how apparently.
I've been googling a ton, and it seems this method is pretty shit, but I'm pretty ass at C and don't know how else my toddler brain can figure it out.
>>54468217
Nested examples shouldn't match either I think
>>54466718
I've been playing around with it, actually.
>>54466740
>mono is shit
So use the CoreCLR.
>>54468238
how is this any different from a file explorer?
>>54468240
if you're thinking of anything other than this, you're probably on the wrong trackint
chars_in_str(const char *c, const char *s)
{
char tab[256] = { 0 };
while (*c)
tab[(unsigned char) *c++] = 1;
while (*s)
if (tab[(unsigned char) *s++])
return 1;
return 0;
}
So I read a little bit about haskell and tried to make a shitty fizzbuzz, feel free to tell me I am retarded and why.fizzbuzz = [if (x `mod` 15 == 0) then
"FizzBuzz"
else
if (x `mod` 5 == 0) then
"Buzz"
else
if (x `mod` 3 == 0) then
"Fizz"
else
show x | x <- [0..100]]
I basically have no idea what I am doing but this seems to work ok. Does haskell have no else if? I only searched a little but I didn't see it. Am I not meant to really use if else's? And I couldn't really find how I am meant to indent or where to break of the if/else etc.
Thanks goys
