Looking for p2p libraries for C/C++. libp2p for C/C++ in other words, but I guess that doesn't exist. Is using a boost-based solution the only way?

PROGRAMMING CHALLENGE

Make a £sd calculator. It must be able to add, subtract in £sd, multiply and divide by decimal fractions. Lowest coin is farthing.
4 farthings make 1 penny, 12 pence make 1 shilling, 20 shillings make 1 pound.

So far, we have a solution in APL, J and C!
What other languages will present /g/ later?

Trying to learn lisp...

How do I use emacs to run a lisp file?

Currently, I'm trying to do

 C-x C-e

, as it says here: https://www.gnu.org/software/emacs/manual/html_node/emacs/Lisp-Eval.html#Lisp-Eval

But I'm getting the error in pic related.
When I run the same code in DrRacket, the code works, so I'm not really sure what to do

I've been browsing some other boards. I have to say /dpt/, you're not dumb. We have disagreements and arguments but in other places people don't even speak at you, nevermind attempt to address arguments.
I had a guy describe an argument me and another anon was having over at /3/ and it's way inaccurate, and the guy I was discussing with somehow agreed with that description. Its like they're brain damaged.

Thanks for being good people /dpt/.

Do I need to learn vanilla JS in order to learn how to use ext JS? I've done pretty much no frontend stuff my whole career (C/C++/python/ruby/Java) but my new project wants me to work on some frontend tickets. How hard is it to learn open source JS frameworks from a backend perspective?

anyone know a good resource for modern C, one that covers the GObject library

>>62141638
that may be one of the reasons, but it made a lot of decisions to make itself easy to learn. english-like expressions instead of cryptic C abbreviation. method syntax and OOP makes it so code completion can remove any requirement of you to memorize libraries. it's a language for the lowest common denominator of being as easy to program in as possible

why does no one realize the ancient prophecy of the golem is upon us?

statues formed from the stuff of the earth, given very literal orders by cryptic inscriptions derived from grimoires and written inside their bodies, and given life to carry out the orders by a raw force of divine might harnessed by learned men

it's all true

stuff of the earth -- copper and silicon

statues made from these materials -- computers and robots

literal orders -- programming

cryptic inscriptions -- source code in text files

derived from grimoires -- standards documents, tutorials

written inside their bodies -- typed in, to be precise, as source code files

raw force of divine might -- lightning

harnessed -- electricity

learned men -- programmers and electrical engineers

given life to carry out the orders -- AC adapters

also it's actually not useless, just redundant
you could declare ints as autos instead if you wanted
this would actually be more idiomatic to C because int is supposed to be the "default" type and everything is supposed to be an int unless indicated otherwise and unless there's a good reason to use a different type

That's called a shimeji. They're actually usually implemented as windowed applications in their own right, but with transparent window backgrounds and borders. No modification to the target window is actually done; the shimeji just knows where to sit by querying the window system for the window's position and positioning the shimeji's window relative to there.
If you want to know more about how to actually make a shimeji, look it up, there are tons of tutorials and such. I'd link you some starter code I wrote for shimejis in Java, but I can't seem to find it.

In C and C++, arrays are continuous blocks of memory. You can't really truly have an array of arrays, because it does not make physical sense in RAM to allocate a chunk of memory where each word literally *is* another allocated chunk of memory containing multiple words. You just can't fit a space into a space smaller than it. C and C++ can *simulate* this, by just allocating an array the size of the product of the two lengths and giving you syntactic sugar to access it as an array of arrays--or, alternatively, by allocating multiple arrays of one length, allocating an array of addresses of the other length, and storing the addresses of the other arrays in the one array. But the latter approach has a different syntax entirely--namely int *arr[]-- and since the prior approach (int arr[][]) is really just a single array, just a single contiguous undifferentiated block of memory--that's only split up into sub-arrays at compile time and not at runtime, and only in the scope in which it was defined--it's not meaningful to pass an "array of arrays" around without knowing at least the sub-array length.

>as a window
Well in the windows DE everything is a window down to the root window. The desktop is just a window containing more windows.
I'd consider it a bit misleading to just say that they're transparent windows (assuming my idea of how they work is correct). They're just windows that sit closer to the root window than most other windows.

Because window click/command passthrough in windows is a mess. Last I tried at least.

You could just make your member variables public. And access them like object.member. But that's against OOP practices. If you're the kind of loon that minds that.

Hi, /dpt/. I would like to learn to make small applications for a daily driver Linux desktop. Nothing too heavy, just got desktop customization, listening to music, etc. Just to make day to day use more fun and simple for me.

I do not know any languages or how to code beyond a hello world tutorial or two. What language should I start with to accomplish these tasks?

  (= 0 (modulo x 5))
  )

(define (divisible-by-both x)
  (and (divisible-by-3 x) (divisible-by-5 x))
  )

(define (fizzbuzz x)
  (cond ((divisible-by-both x) (print "FizzBuzz"))
        ((divisible-by-3 x) (print "Fizz"))

do I go from here? I need some sort of intermediate project to do but i'm unsure what's
within my reach. A Tamagachi sorta thing might be cool but ai is confusing.

I'm 26, is it too late to go back to college for programming? I'm thinking about just doing my local community colleges (though in CAnada they're just called colleges) 2-year program. They have a 98% placement rate and you have to do 2 co-ops during that time, which is basically a paid internship.

The next intake is for Winter/January 2018. I was thinking about taking it, and trying to self teach in the 3-4 months before hand. is it worth it or should I abandon all hope? And, what websites are good places to start learning C# or Java?

>>62143580
no its absolutely not too late. caveofprogramming on youtube (lmao) is a pretty good java tutorial if you have never programmed before.

Why does this work:

    }
    public tuna(int h, int m){
        this(h,m,0);
    }
    public tuna(int h, int m, int s){
        setTime(h,m,s);
    }
    public void setTime(int h, int m, int s){
        setHour(h);
        setMinute(m);
        setSecond(s);
    }
    public void setHour(int h){
        hour = ((h>=0 && h<24)?h:0);
    }
    public void setMinute(int m){
        minute = ((m>=0 && m<60)?m:0);
    }
    public void setSecond(int s){
        second = ((s>=0 && s<60)?s:0);
    }
    public int getHour(){
        return hour;
    }
    public int getMinute(){
        return minute;
    }

    }
    public String toMilitary(){
        return String.format("%02d:%02d:%02d", getHour(), getMinute(), getSecond());
    }
}

But this doesn't:

    public tuna() {
        this(0,0,0);

        setTime(h, m, s);
    }
    public void setTime(int h, int m, int s){
        setHour(h);
        setMinute(m);
        setSecond(s);
    }
    public void setHour (int h){
        hour = ((h >= 0 && h < 24) ? h : 0);
    }

        minute = ((m >= 0 && m < 60) ? m : 0);
    }
    public void setSecond (int s){
        hour = ((s >= 0 && s < 60) ? s : 0);
    }
    public int getHour(){
        return hour;
    }
    
    public int getMinute(){
        return minute;
    }
    
    public int getSecond(){
        return second;
    }
    public String toMilitarytime(){

Note that as you said most of the stuff you want probably already exists. First look if well-tested and featured programs are available somewhere. You can use Python to make them start/modify like you want. Then if you really need something new you can think about writing new.

I have a very poor impression of pycon now. I just wanted to know how AND why data scientists/astronomers use python (because they do, it's popular).
So I found a video: https://www.youtube.com/watch?v=W9dwGZ6yY0k
I'm 13 minutes in and he just said that the software they use to analyse 30TB of data per night is python, and some C++. But the majority is C++.

Why would anyone let this guy talk here? All he's doing is presenting telescopes as if the audience doesn't understand that they're cool tech that does a lot of processing. I just want to know why python is used. I don't see any reason for Python over any number of languages.

>because python is a lot easier than c++ and other OOP languages
Python is a lot more complicated than tons of other languages and just because something is easier than C++ doesn't mean its good or good enough. It says nothing.
Why you'd need OOP for data science is beyond me. For any statistical work it tends to be very forced at best.
It's not an explanation. At best it's a motivation for the fit. Which I don't see. Virtually nobody used python before the mid 00's and it doesn't have the advantage of adoption at all.
Look at https://en.wikipedia.org/wiki/Timeline_of_programming_languages#2000s
and the 90s. There's no way Python is somehow more fit for scientists than a declarative language like haskell. Or a language that both the library authors and the users could use like D which doesn't have all the hassle of bindings. He even quoted a guy who's addressing the disparity between 'developers' using languages other than python while astronomers don't as a problem. But he's kinda sly and framed it as if everyone should move to Python.

He's also presenting advantages like pic related. This has nothing to do with python at all. It's such a silly talk.

I just wanted to know why they use python. I'm sorry your answer isn't sufficient. And I'm not even directing this at you, sorry. I'm just ranting.
It's just very frustrating to have a question and have a guy waste my time for 30 minutes while he's saying nothing to aid that.

The best he said was a point "Simplicity and dynamic nature". By dynamic nature he means that it's fit to exploratory design (which it isn't, it's quite terrible at that actually). Simplicity was just him pulling the "it's pseudocode but executable!" as an augment for it being an intuitive platform. Which just isn't true.

Worthless conf. Even if I can just buy all his claims he has said next to nothing about how python fits aside from being able to use CFFI.

So I've made a PR on github and the owner requested some minor changes. Can I just amend my commits and force push them in the branch on github? Will the PR be updated automatically?

I'm asking because I've read it's not recommended to rewrite history with force push once you've published the brunch.

>>62146031
why would you ever force push

>>62146048
Because I don't want to make a separate commit just to fix a typo.

>>62146058

make a small improvement or update and also fix the typo in one commit
then the commit message can be
>Implemented xyz
instead of

>>62146058
>Because I don't want to make a separate commit just to fix a typo.
Don't worry about it. People typically don't mind those sorts of things.

>>62146094
What if I made a typo while implementing this improvement? It looks like a slippery slope.
>>62146105
I was been asked to tidy up history in a branch before making a PR once because it was full of small typo-like commits.

>>62143528
you need to do (quote (((hotdogs))) ), or '(((hotdogs))). This will make scheme read the (((hotdogs))) as an object, rather than an expression. Right now it's trying to call (quote hotdogs) as a function, because you're using the syntax (<function> <arg> ...), where in this case <function> = (quote hotdog), and there are no arguments

Btw the ' means "wrap the following thing in (quote ..)'

>>62146142
>What if I made a typo while implementing this improvement? It looks like a slippery slope.
>I was been asked to tidy up history in a branch before making a PR once because it was full of small typo-like commits.
At that point, histroy-rewriting would be appropriate.
Typically, people will git rebase on personal copies of a repository. Once it hits 'master', then it shouldn't be messed with.
It would be fine to do it on your PR.

>>62146237
Sometimes maintainers will squash your commits before merging your PR, but I guess they must just be lazy to make you do that instead

How do I use lambdas?

#include <iostream>
using namespace std;

int main() {
  cout << []() -> int { return 200; } << endl;  // prints 1
}

>>62146528
Can you just put the parens on the end of lambda in see plus plus to call?

didn't you forget to call it?

cout << []() -> int { return 200; }() << endl;

function pointer syntax is the grossest part of C

>>62146637
https://cdecl.org

I'm working on an interpreter for a language similar to brainfuck and I want to implement syscalls. How would you proceed, /g/?
I'm thinking about adding an instruction like syscall(arg_count, arg_type, arg, arg_type, arg, ...) with each argument being in its own cell but I feel like it would be a lot of work to manually write programs using this method.

>>62146663
Pointers in general are handled badly. C was designed to be terse and easily parsed at a time when using your computer cost you money in printer paper, not to be easy to read.

>>62143324
>people only bitch about oop because they're not smart enough to use it properly
no, people bitch about oop because nobody else is smart enough to use it properly.
the argument of "i don't need any libraries, i'll just write everything myself" is obviously lost very quickly on languages that can't do syscalls (effectively, without native libraries).
it's made clear that this is the case by java's lack of operator overloading, an abstraction it basically does have with strings (they're even optimized out if they're compile-time constants) but it lacks for users because in c++ the babbling retards use them so heavily that the code they excrete can become unreadable to literally anyone.
it's funny too, because operator overloading generally has a lot more ABSTRACTION capability than oop, which is really just first class functions for methods at best (using it as anything more is any easy method to do it The Wrong Way).

>want to try to learn programming again
>realize I have no idea what I would actually make with it
>already hate web shit
what do

>>62146683
You're right. C's type system is very inexpressive, there's no way to know if int* is null or not, if it's a single value or an array, etc. That's always irritated me. It's nice to write a function signature that perfectly explains out the interface to that function.

Still. It's terse.

>>62146711
Make games. First stupid games where you have to guess a number, then clones of simple games such as pong, snake or tetris. Once you can do these games you're able to learn to make anything.

>>62146723
Seriously, I don't know why people keep making new systems languages outright. All everyone actually wants is to write C with less shitty syntax and grammar. That shit would spread like wildfire.

>>62146696
>OOP is just first class functions
Real (smalltalk) OOP is more than. First class classes are a thing. You wouldn't find that in C++ but when you have them OOP makes more sense.
General OOP (the kind you find in C++, that's the kind everyone actually writes) is generally for people who don't know anything else.
So it's easy to see why they defend it. Having absolutely no idea of what systems can be like except for their meager imperative code when they were learning and OOP certainly makes OOP seem like a very good option.

>>62146736
what's a good source for how to make interfaces then? just terminal shit would be fine, but this part is what loses me

>>62146754
There are some good things about Rust. Error handling and enums in general are comfy, for example.

>>62143528
It has to do with evaluation, typing ((hotdogs)) at the REPL tells lisp to evaluate the call to the procedure hotdogs once (hotdogs) and then whatever that call returns evaluate it as a procedure call itself, I'll give an example of an environment where such a call is permissible/possible:

1 ]=> (define (hotdogs)  (lambda () (display "Hello, world")))

;Value: hotdogs

1 ]=> ((hotdogs))
Hello, world

So any list will be treated as a procedure call or a special form by lisp, unless you tell it not to, and say this is a list do not evaluate it as a procedure call, the way to do that is to quote it, the whole thing

1 ]=> '(((hotdogs)) (and) (pickle) relish)

;Value 13: (((hotdogs)) (and) (pickle) relish)

>>62146754
Syntax is not the only thing wrong with C. Header files, forward declaration, shitty type system should all disappear if you bother creating another programming language.

Wew, lad.

>>62146831
Well I won't blame you, even though I feel like any new languages should strive for something better I really like what it enables.
But it's the same reason I like dynamically, weakly typed languages. It lets me do disgusting and fun things that shouldn't be done in any real program.

I'm reading the book "Expert C Programming: Deep C Secrets" and the author says that this is not a strictly confirming program and I don't know why.

#include <limits.h>
#include <stdio.h>

int main() { (void) printf("biggest in is %d", INT_MAX); return 0; }

It also says
>Furthermore, a conforming compiler must compile and execute a program in which all the limits are tested at once. A surprising thing is that these "required" limits are not actually constraints - so a compiler can choke on them without issuing an error message.
which I don't understand.

I don't fully understand the sentence, but it appears he's saying that you shouldn't rely upon the defined limits like INT_MAX because they may be inaccurate

though in practice, everyone does

>>62146929
At least with exceptions you don't have to litter your code with `if err != nil` every other line, you only have to write error handling once. But yeah, both are unsafe shit and inferior to Haskell/Rust-style monadic error handling.

I want to hurl. Parenthesis dropping is absolute hell.

its really not, especially when chaining functions.

x.thing.thing2.thing3

is much cleaner and nicer than

x.thing().thing2().thing3()

>>62147435
that just looks like a bunch of nested structs.
invoking a procedure, especially a function with side effects like writeln, should be explicit. It's not a data member.

>>62147435
No, it's not, it's extremely confusing, I want to see the difference between calling a method and accessing a member.

>>62147475
>between calling a method and accessing a member.
its the same thing for a single arg, although parenthesis can be there if you want.

>>62147505
not if there are side effects

>>62147505
> parenthesis can be there if you want.
It's nice, but who the fuck thought making them optional is a good idea?

>>62146795
There's a whole science of type systems, and its relation to reliable software, you're an idiot anon.
For what it is C is just perfect, small compact and permitting modular architecture with means to both implement high level data structures and algorithms and to access low level hardware, to appreciate the elegance and minimalism of C take a look at the BSD implementation of the shell utilities, the regexp engine, it is a thing of beauty, truly.
If I ware to choose just two languages to take with me to a deserted Island I'd take C with a lisp that can communicate with it, if just one is permissible then C it is, and I'll implement lisp on top of that.

>>62147435
in racket

(send (send (send object method <arg ...>) method <arg ...>) method <arg...>)

can be rewritten as

(send* object 
           method <arg ...>
           method <arg ...>
           method <arg ...>)

Parentese dropping is only for single args.

Go home, rms, you're high on feet fungi.

crystal is a good language it's like c++ but minus the way too many ways to do the same thing and plus sophisticated type inference that makes it feel like you're using a dynamic language and simplistic ruby style syntax that lends itself to embedded dsls

It's not "functional" or even new, it's basically `;` from Smalltalk-80.

>>62147580
it doesn't have to though because unlike in a dynamic language you can always be explicit with types if you want to and it won't slow anything down because checking is done at compile time

>>62147590
I agree on Lisp being one of the easiest to implement and C being the most performant, but neither of these make means the language in question is any good: brainfuck is trivial to implement and assembler theoretically outperforms C, but I wouldn't use either for a non-trivial project.

>>62147613
>This meme has to stop.
it's true though
it's an object oriented imperative language that's implemented in C and compiles to native code
C++ is also an object oriented imperative language that's implemented in C and compiles to native code and there aren't many others in common use to speak of

I bet Java outperforms whatever native code Crycal compiler generates, especially if you consider that the main thing that holds both of them back is GC, something Java folks have been improving for 20 years.

Actually Crystal is much faster than Java. It's faster than Go, and Go is faster than Java, so there you go. Granted, pictured here is only a single design problem being tackled, and the graph is being shown from a biased source (the Crystal project itself), but if you search for yourself "is go faster than java" you'll find the general consensus is that it is, and if you search for yourself "is crystal faster than go" you'll find the general consensus is that it is. (I just did this myself just now to make sure.) However, if you search "is crystal as fast as c," which it claims to be, you'll find it usually isn't, actually.
