C++ is a horrible language. It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it. Quite frankly, even if the choice of C were to do *nothing* but keep the C++ programmers out, that in itself would be a huge reason to use C.

In other words: the choice of C is the only sane choice. I know Miles Bader jokingly said "to piss you off", but it's actually true. I've come to the conclusion that any programmer that would prefer the project to be in C++ over C is likely a programmer that I really *would* prefer to piss off, so that he doesn't come and screw up any project I'm involved with.

C++ leads to really really bad design choices. You invariably start using the "nice" library features of the language like STL and Boost and other total and utter crap, that may "help" you program, but causes:

>infinite amounts of pain when they don't work (and anybody who tells me that STL and especially Boost are stable and portable is just so full of BS that it's not even funny)
>inefficient abstracted programming models where two years down the road you notice that some abstraction wasn't very efficient, but now all your code depends on all the nice object models around it, and you cannot fix it without rewriting your app.

In other words, the only way to do good, efficient, and system-level and portable C++ ends up to limit yourself to all the things that are basically available in C. And limiting your project to C means that people don't screw that up, and also means that you get a lot of programmers that do actually understand low-level issues and don't screw things up with any idiotic "object model" crap.

So I'm sorry, but for something like git, where efficiency was a primary objective, the "advantages" of C++ is just a huge mistake. The fact that we also piss off people who cannot see that is just a big additional advantage.

But I'm sure you'd like it more than git.

hi /dpt/
what is the most artisan and organic programming language?

I've got some regex for pulling IDs from eroshare and imgur URLs using Python

Imgur ID regex
^(?:.*/)?([a-zA-Z0-9]{5,7})(?:[/?#.].*)?$

Eroshare ID regex
^(?:.*/)?([a-zA-Z0-9]{8)(?:[/?#.].*)?$

Are these ok? I use regex.search(url).group(1) and it works so far, I've run a program using these against 2000+ URLs without error.

My regex knowledge is shit though, every time I need a new one I have to look up all the symbols and shit again or I find something on StackOverflow.

Only language who adopted the Contributor Covenant:
>>Open Source has always been a foundation of the Internet, and with the advent of social open source networks this is more true than ever. But free, libre, and open source projects suffer from a startling lack of diversity, with dramatically low representation by women, people of color, and other marginalized populations.
>Part of this problem lies with the very structure of some projects: the use of insensitive language, thoughtless use of pronouns, assumptions of gender, and even sexualized or culturally insensitive names.
>Marginalized people also suffer some of the unintended consequences of dogmatic insistence on meritocratic principles of governance. Studies have shown that organizational cultures that value meritocracy often result in greater inequality. People with "merit" are often excused for their bad behavior in public spaces based on the value of their technical contributions. Meritocracy also naively assumes a level playing field, in which everyone has access to the same resources, free time, and common life experiences to draw upon. These factors and more make contributing to open source a daunting prospect for many people, especially women and other underrepresented people. (For more critical analysis of meritocracy, refer to this entry on the Geek Feminism wiki.)

>>58832608
No it isn't. OOP actually works well for medium to large programs in teams of programmers who know what they are doing not just one guy trying to make a complex project who doesn't know what he is doing.

>>58832643
Haskell has one major flaw, which is it's bad at the kind of reason why you'd use C or ASM, i.e. explicit memory management, allocation, cleanup.

I'm working on a binary tree in C, the function that creates my tree out of an array of numbers is finished, rate my shit code

Node *createTree(int a[], int size) {
    Node *start = newNode(a[0]);
    Node *temp = start;
    for(int i = 1; i<(size/sizeof(a[0])); i++) {
        temp = start;
        while(temp->data < a[i] || temp->data > a[i]) {
            if(temp->right == NULL && temp->data < a[i]) {
                temp->right = newNode(a[i]);

This is what happens when you are taught Python or Java as one of your first languages or your first languages that depart from what you're used to.

How do I untrain my mind from this mindset that everything has to be objects? I can't even go basic algorithms anymore in functional languages because of it.

What it do?

Every time you see something, think "value" or "type" (in some systems they're the same)

>>58832689
Every large OOP codebase I've seen either:
1) Breaks the rules of loose coupling and/or high cohesion
2) Has an absurd number of layers of abstractions that make it incredibly difficult to find the code that actually does shit, due to how many levels of indirection there are
3) Is partly procedural, partly OOP (this generally seems to be the best 'OOP' code)
4) A mixture of 1 and 2

If you can point me to an open source repo of what you would consider "good OOP code" I would appreciate it.

Because you have to walk a tightrope every time you make a program. If you fuck up even slightly, shit blows up. Other languages are usually more forgiving.

The Photoshop plugin interface is stupid complicated. :-|

>>58832946
Depends on what the problem at hand is. If you do a naive implementation of the Fibonacci sequence recursively, it'll get slow as fuck pretty quickly since you'll end up repeating the same calculations over and over again. Creating a binary tree recursively on the other hand shouldn't cause significant slowdown, but I don't know the numbers on that.

Modern Amiga is on PowerPC, not Motorola 68k; and furthermore, GCC supports both. Presumably, you can just compile GCC 5 or higher and binutils for the appropriate target triplet, and you'll have a working C11 compiler for the platform.

>>58832905

Windows filepaths don't really need to be treated much differently from Unix filepaths. Windows will not complain if you use forward slashes for everything.

>>58833056
Powershell is a cunt with unusual paths though

>>58833013

Why should beginners use more forgiving languages? They should be made to think before they type.

>>58832843
>Learn 3 or 4 different languages
Preferably ones that are quite different to each other - it doesn't really count as 2 languages if you learn Java and C#. This will allow you to see what aspects of programming languages are similar - which constructs can you generally expect to find, etc. Learn a high-level managed language like Java or Python. Learn a low-level unmanaged language like C. Learn a scripting language like Lua. Learn a functional language like Haskell, Scala, or Scheme. This will make it incredibly easy for you to pick up a new language when you need to and help you understand computer programming better. And I don't mean "learn" as in "master". You don't even need to learn the whole language (I have friends who write production C# and don't even come close to utilizing the entire language). I just mean put a couple months into them and write a few toys, though if there's something unique about the language then don't avoid it.

>There is no such thing as a silver bullet and anyone who says otherwise is selling you snake oil
Yes, some paradigms/tools/frameworks/languages are more effective in certain circumstances than others, but you're never going to find a language that is optimal for all possible use-cases. This ties into the first point, which is has the nice effect of keeping you from boxing yourself in with one language.

That said, there is nothing wrong with using a tool that isn't best for the job for learning/fun purposes.

>>58833079
they should learn an easy language like Haskell instead

>>58833038
>Modern Amiga is on PowerPC

As long as it's small enough for NTFS not to bitch at you, it's fine.

>spaces, brackets, everything else
Like any shell on any modern operating system, Powershell is going to see two things separated by spaces, and treat them as two separate arguments. When one argument is enclosed in quotes, it ignores all other syntactic rules, and treats it like a single string. For some characters, you will need to use escape characters. Powershell is okay with that. Again, I will continue to note not to use backspaces for separating directories.

If you are able to teach object orientation properly, yes. Java is alright.

Kinds of people that hate on Java:
1. NEETS (70% of the hatred):
You will find them to be expert on meme languages like hasklel and other bullcrap that has no practical value. Their brain was unable to grasp OOP so they must look tough by posting the most 1337 implementation of fuzzbuzz using functional programming.
2. Microsoft Shills:
It should be obvious. Microsoft saw the success of Java and couldn't stand Oracle. So they made a Java rip-off called C# and started the popular Java hatred meme. The NEETs described in category 1 took the bait and forgot how shitty C# itself is.
3. Lastly, the ""expert"" C kernel hackers who hasn't programmed anything but fizzbuzz tier pet projects. They like to pretend they are some kind of epic anonymouse programmer but as soon as you actually throw a real problem at them to solve they will disappear. They tend to forget the hard truth that no matter how much they study and work on C, they can never be even anywhere close to Linus Torvalds. Other common traits they've got:
>They have programmed a sophisticated web browser that doesn't work
>They tend to be hipsters - avoids GNU and pretend they are any (ANY) better programmers
>When faced with deeper C topics, they won't answer, because they don't know how to work with it.
>Post books they haven't actually bought

ya that does sound pretty comfy. I was thinking maybe just get some big pillows and lay on your bed with your laptop. That sounds comfy.

Just in case you're still here... By some view points haskell might actually be even more of a meme language than Lisp when it comes to getting shit done.
One thing that gets in the way is that haskell's terse syntax that does a lot of things behind the hood is hard to read / understand for beginners. Another painful thing about haskell is you can forget about using for anything that requires a thorough degree of control (Allocation, Deallocation, Any detailed and specific memory management). OH, and probably one of the biggest problems is as much as the haskell community likes to brag about documentation... The documentation and resources for learning the language really blow.

Basically, the goal of being "Pure" makes doing things that are relatively common in other languages a bit more painful or in some cases terrible in haskell.

As in, teach modern Java, and not skip over everything that happened to the language and ecosystem post 2007.

It's fucking retarded.

Java is optimized for large projects. It is supposed to let you wrap shit up in easy-to-use classes.

You end up with your own flavour sprinkled on your frameworks letting you do things more easily.

There are people who don't even know that java.util.Scanner exist. They read from files, streams, etc. by creating an InputStream, wrapping that in a BufferedInputStream, and then wrapping THAT in a fucking InputStreamReader, so that they finally get some decent methods to call.

Who the flying fuck wants to work like that?

>>58833369

It might be a good idea to figure out what exactly you wish to create before needlessly expending energy learning to use random tools for creation.

Which languages to learn from a practical stand point are largely dependent on the problem domain you wish to specialize in.

Follow a book or take a class that teaches you the basics like data types, variables, operations, functions, classes, importing modules, interfaces, inheritance...

Python is very good for this, because you don't have to fuck around with confusing IDEs or compiling.

Once you're familiar with those concepts, (just to the point where you know what you have to look up when you see it again), it's time to study how things are made, like web apps, desktop applications, plugins, and so on.

The best way to study is to do your own personal project in the categories that interest you. Then just reference examples. Doing so will take you on a journey through many languages and technologies.

>Also, your code seems to segfault at s[finish_index] = '\0';

I'm presuming you're doing this on Linux? Look for a package along the lines of g++-mingw-w64-x86-64. The command for compiling will be x86_64-w64-mingw32-gcc, or x86_64-w64-mingw32-g++, depending on whether you are using C or C++. You will also want wine for testing your application. Otherwise, pretty much everything is like using GCC anywhere else.

>>58833926

sizeof(char) * (strlen("test string") + 1))

since you must include the extra space for the terminating null character

>>58833926
There are a lot of things wrong with your code:
>(char *)
Don't cast void pointers. It's pointless and just repeats information.
>sizeof(char)
This is pointless, as it's guaranteed to be 1.
>strlen("test string")
This doesn't leave space for the null terminator.
It should be strlen(...) + 1.

>>58833970
>This is pointless, as it's guaranteed to be 1.
>i like using magic numbers in my code
kys faggot

>>58834007
It's extremely clear from context, and in that particular example, there wouldn't be any number at all.

>>58833942
>sizeof char

>>58834212
there's literally nothing wrong with this. it is evaluated at compile time and improves readability and intention.

why is my program segfaulting when I try to assign something to a particular array? i assigned it memory with malloc(), but it still segfaults 100% of the time when I try to give it a value.
any ideas why, /g/urus?

>>58834252
>improves readability and intention
All it does is clutter up the code.

>>58834257
You're going to need to post the code.

I know basics of C++, pretty much up to classes/structures.

How do I improve from here? Should I pick up a book or perhaps find a task to accomplish and learn along the way?

Also, how hard is Java to learn? I'm kinda turned off by its syntax and I'll have to learn it later on through college courses anyway.

>>58834262
>All it does is clutter up the code.
opinion discarded

>>58834288
It provides no useful information that wasn't there already.
It's the exact same reason that casting void pointers is stupid.

>>58834284
the syntax is the easy part

>>58834295
>It's the exact same reason that casting void pointers is stupid.
Doesn't C++ get pissy if you don't cast void pointers?

>>58834309
>C++
Get the fuck out of here, you shit-eating moron.

>>58834295
>It provides no useful information that wasn't there already.
It does. It provides the information that the data will be use as a memory for a C string.

>>58834338
Or perhaps the fact you're assigning it to a char * would do that, and the size is calculated from a strlen.

Definitely your problem..

It also doesn't help that the more "Corporate acceptance" a language has the more likely it is to be horseshit to maintain / use.

Personally, I think mainstream corporate languages influenced by the same people who decided they need to fill every major logo / product with /x/ style symbolism and bullshit. It'd explain why Java, Node.JS, and .Net bullshit got so big.

>>58834838

>do I absolutely need windows 10 if I want to make a game for it on Monogame?
By the looks of things, no. From the Monogame website, it seems it works with versions of Visual Studio as far back as VS2010, and furthermore, it appears that VS2015 (the latest version supported by it) does, in fact, support Windows 7. You should have no problem developing Monogame applications on Windows 7.

>Any alternative that won't make me install Windows 10 but I will still be able to make a game for it and 8 (I have 7)?
You can always develop on Linux as well.

>>58834802

>>58834939
It supports windows 7 but says I need to have windows 8/10 to develop for 8/10 meaning a game wouldn't work on those OSs and I don't get why.

>>58834959

Develop and test the game on Windows 7. It will work without modifications on Windows 8 and 10. Presumably, you would need 8 or 10 if you wanted to make some sort of Metro/UWP game with Monogame.

>>58835027
alright I guess microsoft and some other were just shilling when they said you needed the OS you were developing for if you wanted it to work on said OS.

>>58835042

It's generally good practice, but strictly speaking, there wasn't too much of a breakage in application compatibility from 7 to 8 to 8.1 to 10.

>It should be obvious. Microsoft saw the success of Java and couldn't stand Oracle. So they made a Java rip-off called C# and started the popular Java hatred meme. The NEETs described in category 1 took the bait and forgot how shitty C# itself is.
Wow, it's just like my chinese cartoons.

Surely, it's not the fact that C# is a much nicer language to use, and the tools and frameworks surrounding it are insanely easy to work with.

>>58835135
You can embed all sorts of things into Sharepoint; it becomes a huge franken-website with all manner of fun things.

Eventually, you get to the point where making a change or maintaining it involves lamb's blood and pentagrams.

Basically, it's so configurable that you need people dedicated to configuring and maintaining it.

};


// Left rotate a list, place the left-most element to the right and 
// return new first element
// NB! This mutates the list argument

And 'map' wouldn't be broken.

Trying to optimize prime number finder/adder, without using arrays. Got it to around 112ms for first 100k'th prime sum with compiler settings, skipping evens, and having to use modulo/making my inner loop increment by 6/other crap. Can't seem to make it faster without having to use arrays somehow. I can't count composites up to a number using loops without somehow storing values (without vectors and bitset as well), and there are repeats if you use inner loops. I don't think I can do anything else.

Your map is unecessary:

Before the Roslyn team even came up with this scripting engine, some other guy's csscript had '//css_ref fn'

Why not include something like that?

nvm, apparently i can just use size_t instead of streampos

why did some tutorial i read suggest i use streampos to save a filesize instead of just size_t?

i think the idea is that it's arguably not the business of the script to specify references, but rather that the code that consumes the script should specify what references the script is allowed to use

Still trying to justify all this work by thinking about how much more efficient this should be than electron for multiplatform applications though.

Best over the counter study aids? Someone has to be redpilled on this.

>>58838205
>>58838462
also note that there's no way to specify an assembly reference for a block of regular C# code either, even with the preprocessor (rather it's part of the build process), because references are an aspect of the assembly, not of any given block of code. so allowing it for scripts is somewhat of a break from style, though it makes more sense since every script could potentially be built as a separate assembly

if you want significant results, drop the over-the-counter requirement and get a prescription for adderall (it's pretty easy). that shit works

Okay, since that's not interesting, what are some of the best things Angular, React and all them do?

>>58838687
That should have been:

    __asm__(
        "fldl %1;"
        "fsqrt;"
        "fst %0;"
        : "=g" (result)
        : " g" (n)
    );

bool ^= 1;

bool = !bool

are these the exact same operations or is the first one actually faster?

>>58838677
It was probably easy to get and worked because you actually need it.

>>58838696
C++'s is fast and powerful but pretty barebones, somewhat difficult to learn to use correctly, and certainly ugly and/or cumbersome at times. C#'s is pretty, extensive, and easy to understand. Java's is probably similar to C#'s but Java is a shit language in comparison. Can't speak for Rust or Go, personally. For the "comfy" heuristic specifically, C# wins for me.

>>58838696
Java because it pretty much has a library for everything and it will get your code to work and run but it won't be the best

>>58838767
The first one is faster, but the compiler will optimize the second one into the first.

>>58838785
> Java's PROBABLY similar
> but Java IS shit
Really made me think

>>58838767
both compile to a single xor instruction even without optimizations

>>58838785
I love people like this say a language is shit for absolutely no reason when in reality Java is a good programming language to work with and when he finally comes up with reasons they will all be non issues in programming

>>58838555
>so allowing it for scripts is somewhat of a break from style, though it makes more sense since every script could potentially be built as a separate assembly

Really, I just wanted it to be flexible enough to use any existing assembly. Maybe somebody wants a script to use their library or something.

>>58838708
have you talked to a psychologist? if you're having trouble focusing on studies/looking for study aids, you might legitimately be the kind of person it's intended for

>>58838768
it was probably easier to get because i actually need it, yeah. but from what i've seen, it "works" for basically everybody (by that i mean it'll help you cram/binge study/work with laser focus)

>>58838798
what if it's actually a ptr to a bool

ptr->bool = !ptr->bool
vs

ptr->bool ^= 1


now it must be faster tho right? because you don't have to lookup 1? i'm having a difficult time testing this because the performance i get running my program varies for some reason i don't understand. but the second one seems to be consistently faster in this case.

well yeah, you can't really use a GC based language for an AAA game otherwise you end up with something like Minecraft that struggles to maintain 60 FPS on modern hardware

>>58838813
>>58838828
Note that I said Java is a shit language *in comparison*. It's a language, yeah, it'll get the job done. Yeah, it's similar to C# in many ways. But C# is also significantly better in so many ways to the point that I would never recommend using Java over C# unless you're restricted by some external factor.

Is malloc really slow for games?
Is that why every engine and game ends up writing it's own memory allocators?

>>58838696
If you want straight up comfy with plenty of out-of-the-box things to work with data, that's going to be C#.

It just werkz™.

>>58838924
it's not slow per se, but allocating memory all the time with a lot of dynamic objects can be costly that's why it's better to just go with something like static pools for those games

I was assuming the standard library is similar. I know about the language features. I especially know what Java is lacking in comparison with C# and it is a significant matter.

disregarding numerous very useful and verbosity-reducing instaces of syntactic sugar features (since those "don't count"), off the top of my head; user-definable value types (huge), unsafe contexts, delegates, ref/out, generic constraints, generics on value types and primitives, covariance/contravariance, value types implementing interfaces with no runtime cost (except automatic boxing/unboxing where applicable)
