I could not clone. I got a permission error.
I went online and they said.
To make sure you are connecting to the right domain, you can enter the following command...

can you move that left hand activity bar thingy to the top yet?

>>61556393
int[] is a real array, but because all object types in Java are reference types, an Object[] is just an array of pointers. Completely shits up up your cache locality. An array of structs in C# really is an array.

>>61556400

Anon that caused a shitstorm because he dislikes the rust book here, is there a good resource on learning modern and idiomatic C++?

>>61556508
Well capslock is a recognizable key, and i looked into the marcos extension but for the command section when making a macro, only mentions commands like editor stuff, and i couldnt find if it supports key actions.

When i get to the command section

"key": "capslock"
"command": "???"

>>61556546
How can it be applied to a FOSS project that originates from MS? That makes no sense.

>>61556531
But they are nothing to do with deallocation of unused memory, which is the purpose of GC, the original topic of the discussion.
C++ and Rust have their own answers to that question.

Clearly, Microsoft is just waiting to instantly delete every repository of VS Code on the entire internet all at the same time without warning, and then hold the world hostage by threatening not to update VS Code any more without a monthly license fee.

>>61556583
This, but only in certain situations.

C# is not a directly replacement for C++, but far surpasses it in usability and toolset for a huge portion of things people traditionally built in C++. At the end of the day, C++ has the ability to be faster, so it still has its uses.

two: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0

>>61556646
It's for

size_t

>>61556658
nope.

>>61556658
wrong

>>61556609
At first I thought you were using size_t to do something tricky, but it looks like you're using the proper format specifier for it in printf. So in the first case it should go from 9 to 0, underflow, and stop, and in the second case it should loop forever, starting from 9, going to 0, and underflowing to the platform-dependent maximum of size_t and then all the way back down to 0 etc.

>>61556690
ding ding ding

1000000 internet points to you, sire.

>>61556682
>>61556685
oh apparently size_t is unsigned, but I still don't see why the first one would be wrong, shouldn't it not loop at all since the condition already fails before the first iteration?

>>61556717
So why did you use size_t instead of some normal unsigned type?

>>61556720
In the first iteration of the first loop, i is 9 and the condition is "i <= 9" which is true. You might have missed the "or equal to" part of the "less than or equal to"

>>61556720
>>61556741
>So why did you use size_t instead of some normal unsigned type?

I have an interview coming up for a job where "programming/automation experience is a plus"

I did some hackerrank challenges already for them, they were fairly basic, nothing too weird; 3 problems in an hour and I got like 70-80% of it

any tips? I've never been asked to code on the spot or asked programming-related questions in an interview

what's the best way to prepare? theory of the language? data structures?
any tips are welcome

>>61557583
I don't understand the question

>>61557595
What is the difference between a struct, with multiple variables, and a class in object oriented programming?

>>61557583
structs are public by default whereas classes are private. Otherwise they're identical.

>>61557575
Calling direct object attributes via the dot operator is very muchso a Java thing when they're not encapsulated.
You can do it in C, but the proper way is Struct->Direct.secondary, because you can't chain dot operators in it.

>>61557604
Struct:
Big box with lots of things in it

Object:
Big box with lots of things in it, and a bunch of tools to help manipulate those things

e.g. Objects have methods inside them, structs are just data containers.

>>61557608
>because you can't chain dot operators in it.

I'm already doing some of that; basically using Python and stuff like Ansible to get data out of various devices, process it, generate configs from templates (I use jinja2) and such
so scripting mainly, not huge projects

>>61557644
Whoa buddy, you need some SAO's in there with a null coalesce on the end.

>>61557604
In C++, there is literal difference between a struct and a class.
As far as the language is concerned, the members of a struct are public by default while a class is private by default. Structs are public-inherited by default and classes are private-inherited by default. Everything else is the same.

You should think of them differently and use them for different purposes. When a C++ programmer sees a struct, he will think it is nothing more than a tuple with named data members. When a C++ programmer sees a struct, he expects some kind of encapsulation and access protection, some member functions, maybe inheritance etc.

Need a little assistance, /g/. I haven't done any serious programming in nearly three years, let alone decode someone else's work.

How can I submit POST data server side to an external website? The external website has the client run and execute a jQuery script that contacts an external website itself.

Or, well, how could I submit data and a response to
>https://www.mycallin.com/index.html

The jQuery script calls to
>https://sentry.norchemlab.com/Sentry/
>https://sentry.norchemlab.com/Sentry/WebCheckin/Lookup/
>https://sentry.norchemlab.com/Sentry/WebCheckin/Log/

Whenever using cURL with PHP I receive
>301 Moved Permanently

Allowing redirects I receive
>Samp::WebApp::WebCheckin=HASH(0x186822b0)

Finally, after submitting the first form, I then have to determine whether or not the received data is for my account by clicking 'submit'.

If I could get pointed in the right direction it'd be greatly appreciated.

Help me decide, /g/. I've been considering starting an open source project. It would be a self-hosted license management system, that can be used to deal with serial keys and serial key distribution, tie licenses to hardware, provide users an overview over licenses and features.

This is probably a project that will take months and some really hard tech stack decisions. I also know there's a pre-existing startup that also offers self-hosting in this area, https://keygen.sh/, though I'm trying not to read their API docs or the like to avoid copying their ideas (API copyright is kind of a hot iron right now). Should I do it anyway, knowing I will probably throw it into the water and/or nobody will use it anyway? There are some interesting technical decisions to make and a stack to design, but that makes failure pretty likely.

Marketing and/or right place at right time.

C++ was marketed with "why would you ever not use it manager? It's just C, but with more! It even places nicely with* your C code!"

Javascript was a prototype for Netscape to run scripts, and it ended up sticking instead of the planned Scheme (never got in) and Java (which got in, but was never fully integrated and eventually got pushed out).

1. Use fopen/fread/fclose for portability.
2. Try reading the file in chunks. Imagine you're dealing with the SQLite3 amalgamation.
3. Having variables both named i and iter is fucking confusing.
4. Use an enum for the comment variable, something like

enum CommentType {
        CT_SOURCE = 0,
        CT_CXX,
        CT_C
};

5. I didn't go through all of copy, but I'm pretty sure that's just strcpy(). If you're on a BSD or can link against libbsd, prefer strlcpy.

The only people who don't consider Scheme lisp are common lisp faggots who insist that only common lisp is lisp and feign confusion when you mention scheme exclusive features.

I'm writing about 50,000 lines to a text file from a Java Array. Works fine up to the 47,678th line, then it just stops in the middle of it and doesnt print any further.
I know its not a loop issue, I'm tracking the last iteration count inside the conditional for printing, and its ending about 400 lines after it stops printing.

I've tried fucking with BufferedWriters buffer size but I've only managed to make the total amount printed smaller, and I've tried using FileWriter directly with no change.

No, it doesn't, it just uses Scheme, which has closures, that's all it has to do with FP. You can't really teach the actual FP with a dynamically typed language.

They switched to python and the new course because (1) they wanted to unify intro courses for EE and CS to save money and (2) they wanted an """empowering""" """application""" focused intro course to """inspire""" students to continue with their degree instead of a fundamentals course.

I don't have a CS degree, but that train of logic is the reason why I had to take SIX calculus courses to get my math degree.

That's because you know "application" pedagogy is a waste of fucking time that doesn't create true understanding and everything learned from it will eventually have to be completely replaced. You know that application focused pedagogy is justified by being more tactile, despite the traditional approach having plenty of rooms for tactile projects.

Using the view count or more buzzwordy, the wisdom of the crowd (see pic). If there's an large influx of people but it isn't the start of the stream there is probably something worth watching. If the view count falls over a certain period they are probably leaving (interesting event ended). At the beginning, I wanted to incorporate the chat for clues but that simple heuristic worked so well that I didn't need any more clues. It was a bit eerie at the beginning because the recordings just started before the action began, captured the whole show and then ended.
The main parameters you want to tune are the time slices and velocity rates

How is this for commenting?

class Vector {

    //Default Constructor
    Vector() {x = 0; y = 0; z = 0;}
    //Standard 3D constructor
    Vector(float xP, float yP, float zP);
    //Standard 2D constructor
    Vector(float xP, float yP);
    
    //Return the vector as a string
    string getVector();
    //Multiply each vector component by the given float value.

It's not necessary to have any explicit constructors desu. You'll just get the regular struct initialization rules.

But if you do, you can just use the same name as the members. With a constructor initializer list, the variable shadowing makes it nice and neat.

Vector::Vector(float x, float y, float z):
x(x),
y(y),
z(z)
{};

I've also seen people prepending _ to constructor parameters as a common style.

>>61560683
>prepending _ to constructor parameters
aren't names beginning with _ reserved?

>>61560767
No, prepending member names with an underscore is common for private members, in python it is in the style guide. It has been done in PHP since the beginning.

Double underscores __ and underscores followed by a capital are reserved. Single underscores are only reserved in the global namespace.
