tfw I want to do more programming on my own but only just learned how to read and write files in C++ and can only write a program when I'm given an assignment.

What do I do /dpt/ the only thing I can do is simple shit with the command prompt and make text files. Everything I can think of or that people suggest doing is too complicated and I don't know how I would accelerate my learning outside uni or if it's even worth it.

I'm wanting to start a project (first one) where I have a script read emails from redbubble / teepublic and adds all of my sales together.

I'd like this to run on a pi zero and have it display the amount on a small lcd.

Is this something that a begginer would be able to accomplish? It sounds pretty simple, but I'm not sure. What language would be best to start this? Python?


Or should I just be using IFTT

>>58578791
>is too complicated
give me an example. no matter the project there's usually a little thing you can break off and play with. that's how everyone starts; but you have to actually be interested in the result

>>58578791
write a program that reads from stdin line by line and outputs to stdout any lines that contain the first argument given to the program. ex

$ echo "Hello\nWorld!" | myProg Wor
World! 
$ echo "Hello\nWorld" | myProg test
$ echo "Hello\nWorld" | myProg Hello
Hello

>>58578799
>Python?
You'll be surprised, but Pi stands for Python interpretator, so, yes.

I wouldn't want you to start from Python, but I don't know other fairly good languages.

I am right now having some trouble with some html code, its a assignment and i basically have to make a chessboard with some symbols. Trouble is my teacher from turkmestan cant teach properly and has offered no resources on learning this stuff so i am surving off khan academy. If anybody has any resources i can read off of or checkout that would be very helpful. Another part i am having trouble with is linking from the home page and organizing my code better, i feel like i am doing everything long hand and it seems to be a bit confusing.

>>58578791
Just try to write something that might be useful to you and don't give up.
My first non-trivial C++ project was an application to manage my anime backlog (something similar to MAL). And years later I still use it daily.
It was pretty hard at the begging but I just kept googling shit non-stop until I got things right.

What's the state of cross-platform runtimes for C#? I'm interested in the language, particularly because of its popularity in some game engines, but I'm a Linux guy and I'm a bit suspicious of Microsoft's influence on the language

This is really important. Don't feel dumb for seeking help. Eventually you stop having to google every step of the way which is an incredible feeling.

Until then, hammer the search bar.

Much of programming is actually just trying to figure out how to compose the simple building blocks in a meaningful manner.

If you know how to create new data types (classes, objects, structs, whatever the language offers in that regard) and you know loops and conditional statements, then you're ready to program a lot of stuff. The problem may be to find a project that interests you enough to actually keep going from your own inner drive.

>>58579240
Learn Nim, it has direct compilation to C and can be ported to javascript. I've been learning it myself recently and it's pretty nice. Either that or ruby

>>58579240
For what purpose do you want to switch? Just to try something new or to embrace a completely new style of programming? Why aren't you happy with Python and what would you like to see in your new language?

>>58579240
Go.

>>58579240
What do you want to do with the new language?

>>58579257
I think I have a good handle on the logic. I think I might do some kind of backlog program that also stores info on stuff I've recently read or played or whatever.

I'm looking for a partner for an online game. I need a programmer who's experienced with HTML5/JS/SocketIO and hopefully phaser.io. I can invest $1000 of my own money into the game, we'd code it together and split the profit 50/50. We can discuss the details of the game together, or I'm open to your own game ideas and we'll collaborate together. Email: [email protected] if interested.

Also, if you haven't already, you could try getting into a library for graphical user interfaces.

You are working as a miserable IT slave and this girl calls you in asking you why the keyboard keeps hitting random keys on the keyboard. It's always low keys like space, ZXC M,. etc. You aren't allowed to say the real reason because HR is full of women who will flip shit and fire you. How do you explain it to her?

I wonder what a neet coder girl's computer chair smells like.

>>58579160
>What does that program do mate?
The first build was just some spreadsheet, much like Excel, where I input values. Later I started adding things like image attachment, advanced search option, google search for the shows, dumped the spreadsheet-like layout for something similar to a flow layout panel, etc etc.

Don't try to do everything at once or else you're going nowhere. Take your time and test each step separately.

What do you think about Haxe?

What do you think about Clojure?

>>58579326
Ask her to start typing so you can observe the issue, then after you see it you fiddle around with the connections and make sure everything is working correctly. Readjust the keyboards position on her desk, then you tell her to make sure the isn't accidentally leaning against the keyboard as she types just incase that's causing the problem.

If you're willing to invest time, then try Scala. You can use it
>as a full scale programming language
>as a scripting language

>as an object oriented language
>as a functional language
The language was a little awkward to me at first, but it quickly grew on me. You absolutely have to do some reading though, it's not an easy language to learn, because there are a lot of conventions and shortcuts that you must have seen at least once before. But there's a lot to learn if you're new to functional programming.

Is the only way to get rid of bad programming habits is to way until someone calls you an idiot while looking at your code, or is there some book/resource that I could read that goes through the most common programming rookie mistakes?

>>58579494
But i'm tired of Python, so I'm not happy with it anymore.

>>58579483
We had a few of those running through here. It was mostly contrarian digression while holding to the original point over non-combatible points.

It just juggled unadulterated opinions and avoided any kind of meaningful transference.

>>58578589
>Quick prototyping language.
Python or Ruby. Flip a coin if you can't decide.

May sound stupid, but I'm attempting to write strings to a binary file using C++, however when I do so they still display as ASCII text, whereas numbers do not when viewed in a text editor.

if(out.is_open()){
    out.write(&message[0], message.size());
}

I can imagine the text editor picks up null terminated strings and displays them as ASCII, but is that the case? The binary flag is active on the ofstream that I use.

>>58579507
Hmm. Maybe if I combine /dpt/'s shitposts with the other generals's the results will be hilarious. There's plenty of 4chan twitters but they seem dead

>>58579503
What does this post state?

>>58579510
I actually hated Scala when I first heard of it. But I've started using it and ... it's not so bad. I guess it's an acquired taste.

>>58579501
Just try looking at why this thing "is this way" rather than "that way" and keep those differences in mind.

The mistakes are shown to you in your compiler error messages. They are shown to you in the chugs and pulls of your computer as it runs your program. Not keeping up with the wave-front algorithm really has less to do with programming than you think. The thing is you keep using google so you are getting results that were tailored in the billions for and by Indians.

Have fun in their little jerry rig.

>>58579541
I've been using Scala at work for the last few years.

It's going through what Java has been through (and a lot of other languages too): a lot of churn in what is considered best practice. Remember the cake pattern?

what will be after nodejs?
>when the next generation of (((programmers))) realizes it's too complex for their feeble minds

>>58579733
No. A language being above C level does not make it good.

It may be good for other reasons, such as good FFI or a wide range of libraries.

>>58579731
I'm saying there's a lot of bullshit thrown around about how to write code in Scala. The language is flexible enough that you can write some truly awful code with the best of intentions, and there will be people cheering you on from the sidelines, but this time next year they'll be denouncing those same practices.

>>58579786
What's your opinion on the matter? Hypothetically speaking, couldn't you just treat Scala as a purely functional language and apply the best practices of other functional languages to it?

how do you visualize bits/bytes? is there even any reason to?

>>58579851
However, scala is retarded due to having its roots in Java. other functional languages have much more beautiful syntax

>>58579851
>Hypothetically speaking, couldn't you just treat Scala as a purely functional language and apply the best practices of other functional languages to it?
Yes, but you pay for it. You really pay for it.

>The bit is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0 or 1. The term bit is a portmanteau of binary digit.

A byte is an array of 8 bits.

1 byte = 8 bit

This is one byte, consisting of 8 bits, each having a value of 0 or 1.

Yo /g/ I know there is a good way to do this but i cant think of it. I am iterating over every day from 1 year ago today. I need to limit my calls to the api at a rate of 20 calls in 10 mins. So my current code goes:

        let startDate: any = Moment();
        let curDate = Moment(startDate).subtract(1, 'year');
        let todayDate: any = Moment();
        let waitTimer: number = 0; //600 seconds = 10 min wait required by Quandl
        let listDates: Array<any> = [];
        let dateStack: Array<any> = [];
        let dateStackNum: number = 0;
        console.log("Start date = "+ startDate.format('YYYYMMDD'));
        console.log("Cur date = "+ curDate.format('YYYYMMDD'));

        for (let i: number = 0; curDate < todayDate ; curDate.add(1,'day'), i++) {
            console.log("Working date = "+ curDate.format('MM/DD/YYYY'));
            if((i%20)  == 0){
              //none of this will work, ideas? maybe make a time out for every 20 dates 
              dateStack[0]=curDate;
              listDates[dateStackNum]=dateStack;
              setTimeout(() => {
                console.log('Calling wait: '+ waitTimer+' seconds i='+i);
                for(let x: number = 0; x < 20; x++){
                  let date: any = listDates[]
                  this.callQuandl(listDates[x]); //calls server requires date
                }
              }, waitTimer);
              waitTimer += 600;
            } else {
              dateStack[(i%20)]=curDate;

I looked into kmap and heard that for "low" memory areas (the kernel address space), kmap just returns the kernel logical address of the page by applying a constant offset. But this means that the kernel will have to reserve physical memory for this.

Otherwise, how can the hell can kmap and kmalloc return kernel logical addresses? I'm very confused.

i am a hobbyist programmer that managed to stumble ass backwards into an actual programming job. most of it is fairly easy (search and destroy bugs, code cleanup, etc.) but i so desperately want to get better at large scale programming.

whenever i look for sample projects that i could work on to improve my skills, they are always the same easy to semi-difficult math-related problems that can be solved in a single class (generate the fibonacci sequence, get pi to the whatever digit, and so on)

is there any source of good ideas for actually semi-complex projects that require multiple interlinking structures to complete?

my job is in c# but i am hoping to do my practice in c++ to sort of kill two birds with one stone by learning a new language at the same time i'm improving my general programming skills.

Of course it's not possible. Remove the lifetime here, it should be attached to the object itself and not the function.

More concrete example:

struct WinPlatform {
  class: winapi::ATOM
}

struct WinWindow<'a> {
  phantom: PhantomData<&'a WinPlatform>,
  handle: winapi::HWND
}

impl Platform for WinPlatform {
  type Window<'a> = WinWindow<'a>;
}

When a WinPlatform is destroyed, it unregisters its window class. But you cannot unregister a window class if there are any windows created with it.

>>58581251
That doesn't even remotely have anything to do with that. Your entire code really shows how little you know about anything you're saying anyway. Here, some handholding just for you, and protip: lifetimes are not arbitrary parameters.

trait Platform {
    type Window;
    fn create_window(&self) -> &Self::Window;
}

struct W<'a> { name: &'a str }
struct P<'a> {  wnd: W<'a> }

impl<'a> Platform for P<'a> {
    type Window = W<'a>;
    fn create_window(&self) -> &Self::Window {
        &self.wnd
    }
}

Sorry, I meant P<'a>, I got confused because of those retarded fields.

No, they're not the same. If the platform is parameterized over a lifetime and it's not the lifetime of a reference to the platform itself, the window could still outlive the platform.

>>58581377
No it doesn't.

Classic.
Your example does not exhibit any of the properties you're trying to produce.
Moreover you have no fucking clue how lifetimes work. If P<'a> { W<'a> } then the lifetime of W is >= the lifetime of P. Fucking retard.

I fucking hate imgur's gifv bullshit. Since what's most commonly in there is an mp4, I put the following script into greasemonkey (first time writing Javascript).

var url = window.location.href;
var pos = url.search("gifv");
var newUrl = url.substring(0,pos);
window.location.href = newUrl + "mp4";

That just makes the page constantly refresh, though. What can I do to make imgur not be allowed/able to redirect me to gifv?

>>58581434
>If P<'a> { W<'a> } then the lifetime of W is >= the lifetime of P.
If you do things that way then there can only be one window. I said create_window for a reason.

>>58581437
>Window should just be an opaque type with all platform specific details in a separate module.
>That makes for a stable binary public interface.
The user can use it as a Window through a reference, but they don't have to if there's some reason to get to the platform specifics.

When, specifically, should you not use auto?

>>58581456
you can't rewrite the url to mp4 because their webserver rewrites it to gifv. if you right click and save video as you can save an mp4.

>>58581428
Unless it's a basic type (int, char) or something that can easily be accidentally implicitly converted to something else (int, char), use it.

Or & / && references. Don't quite have those grokked myself

>>58581463
>but they don't have to if there's some reason to get to the platform specifics.
If they're gonna write platform specific code, why go through an extra hoop of a generic Window? Not gonna be able to use any common code anyway, just use WinWindow directly.

>>58581472

Ok

>>58581484
1) when you definitely want a specific type that you know it won't specifically infer
2) when you're using some obscure templated overloaded function and you want to make sure the result is exactly as you expect

>>58581491
You know what, I hadn't thought of that. I can probably make it work. It does mean I have to have two different method names instead of using create_window for both.

>>58581489
auto&
auto&&

const auto&

etc

>>58581491
>>58581523
Well I don't mean that I'm going to do that specifically, but have a trait that returns a Window reference and the object itself has a platform specific create method that returns a WinWindow.

I'm looking into coding a proxy, but i'm torn between Java and C#. Any tips on the pros and cons of each?

>>58581072
>is there any source of good ideas for actually semi-complex projects that require multiple interlinking structures to complete?
What do you mean by "interlinking structures"? If you want a large scale deployment, decentralized services like my TV project (>>58580424) might be interesting.

If something like that isn't for you, maybe machine learning. If you have any scientific or mathematical background, you can try making a BOINC project to do some research in a weird field. Personally, i wanted to make a Game of Life project that searches for multidimensional quirky shapes and create a giant academic paper on the findings.

>>58581485

I'm not trying to save it locally; I want to view it in my browser normally.

The frustrating thing is that SOMETIMES when I right click on it and select 'view video', it will go to the mp4 and won't redirect back to gifv. Other times, it ALWAYS redirects and there's nothing I can do, as far as I can tell. I want to never be at a gifv page again.

What can I do?

Or, well, I suppose it does because the lifetimes get inferred there. But if you want to actually create a window you can't use a reference, you have to use a box or something that's owned and put the lifetime parameter in the window type itself.

That's what I've settled on already.

Either you have window creation code and you're yielding the window completely (i.e. it isn't tied in any way to the platform). In that case you can return the window verbatim.
Or you can tie the window creation to something (such as a registry). In that case you must yield a reference, not the object itself. I also can't think of a reason why you wouldn't use a reference in the latter case.

>Either you have window creation code and you're yielding the window completely (i.e. it isn't tied in any way to the platform).
I already explained that this isn't the case, since the window class (managed by the platform) needs to outlive all of the windows.

>>58581715
So you're trying to leak memory on purpose? It sounds like you're trying to have a reference to the window, not the window itself, tied to the platform.

it's one of the strengths of java, that a codebase will stay accessible to very large teams of programmers and new programmers because of its simplicity. operator overloading often gets abused and it's mostly unnecessary. if you want the developer to have total control of everything you may as well use C++.

I'd say fix your browser to play gifv properly like Firefox and Chrome already do.

Noun. (plural personal attacks) Making of an abusive remark on or relating to one's person instead of providing evidence when examining another person's claims or comments.

Personal attacks are attacking the person, instead of providing facts and evidence to an argument. What you were implying is wrong.

>>58581996
Not an argument.

Why are Java babies so affected by linguistic relativity?

Does Java have event/delegates?

Yep, I came to that conclusion about 15 minutes ago in the shower.

no thanks

>>58582118
shouldn't that be

&& (i % 7 != 0)

also you shouldn't be computing these twice

Backtracking solves puzzles like mazes, and Sudoku. It's a clever technique.

i know what it isn't

for simple things like that, gcc/clang will produce optimal or near-optimal output. in non-fizzbuzz code you might store things in variables but it's mainly done for readability

trying to learn java/android programming
but i have a hard time since it's not 'relevant' to my life and i don't have much time to practice.

i think that if it were my job i'd be able to pick it up easy like every other job i have done.

is there such a thing as on-the-job-training for java/android devs?

if so, where can i find one that doesn't require CS degree/huge portfolio/knowing everything already?

Dickwoman here, please don't associate us with Node.

should you be ashamed if you constantly forget syntax and google it?

>>58582327
I sometimes need to lookup for simple shit like the form of a switch, or an enumeration. And I've been programming for like 4 years as a hobbyist.

>>58582327
you should be ashamed for using a syntax-heavy meme language

>>58582429
If what you do is easy you are easily replaceable.

>>58582327
no because some shit is not worth remembering. Problem solving and math is more important than code

>>58581992
Oops, it's .net and not .com
Git gudder next time.

>>58582507
it's not about the syntax

>>58582874
agreed

>>58582429
Syntax heavy doesn't really mean unintuitive
