Take the test at openpsychometrics.org/tests/IPIP-BFFM/ and post your neuroticism score. Regardless of that, I can recommend the programming experience pill. Once you've been forced to ship enough fucked code and proven yourself able to unfuck it later, the anxiety subsides. Not programming right before bed helps you avoid programming dreams.

create-react-app is boilerplate that comes with web pack, babel, react router, and some other stuff I can't remember right now. If you're learning react I'd use it for now until you're ready to dig into setting up the environment. The create-react-app documentation should be pretty easy to follow to get started.

It is this way because Webpack and the ecosystem around it are an autotools-tier convoluted mess. Parcel is rather less painful. Look at github.com/jaredpalmer/react-parcel-example.

Of course. Today is the 20th anniversary of SEL's first airing. Gonna rewatch Lain tonight.

I want to make stuff with C but I'm really not all that interested in embedded systems and there's only so much you can do by making dynamic arrays and search algorithms.

Should I just start learning C++ if I want to get into stuff like desktop applications or gamedev?

The problem comes when I then have to weave in redux, react-redux, react-router, react-router-dom, react-dom... basically react-.* and I have no idea how anything fits together. It's all just a black box. I've tried a few times but always wound up with some compilation error in a 3rd party library due to some missing dependency or whatever.

Sure I could just use pure react for the view layer, but part of the allure is supposed to be that it's a very powerful framework that has everything you need for the frontend. If I can't get at least the same level of power/convenience out of it as a much simpler vue/vuex/vue-router setup there's no point.

>Should I just start learning C++ if I want to get into stuff like desktop applications or gamedev?
Yes, C++ with Qt Or C#.

>C
>desktop applications
Integrate your C code with Tcl/Tk. tcl.h will give you battle-tested implementations of data structures like real strings and dictionaries.

Yeah I figured, plus I have some experience with C#. I've been meaning to play with SDL2 as well.
I've never heard of Tcl/Tk but it looks pretty neat. I'll look into it. Thanks!

can someone give me a quick primer on SOAP and SAML? need to integrate our express backend with an older system at work and going from REST to SOAP is a bit confusing -- especially with this whole SAML gimmick

Why are you going backwards in time? Do you need to integrate with AD or something?

C++ is pure trash. It's completely unethical to tell people it even exists.

i actually integrated with AD a few weeks ago and that was surprisingly easy with a handy node module.

we need to integrate with some government services and their system's are using SOAP

If you want to do game dev (graphcis programming) the proper way, C++ is your only real choice. If you're going to learn C++, you might as well learn Qt as well so that you can make non-shit cross-platform applications. Stop being so dogmatic, you probably haven't even used the language for more than a month.

Good job falling for the retarded memes.

Lain is a slut.

>follow the herd you stupid goy

>he thinks he can make his game with monads

Thank you friend, I started with The C++ Programming Language at first, but they immediately started with things like without any explaining to what that is, so I thought the book was really just a reference.
Ill continue with it then, it was probably just an example.

seriously though what are decent alternatives to C++ when it comes to video games?

If you do not want to do low level graphics programming, just use Unity or Godot or Gamemaker or some other engine. If you want to do graphics programming, you man up and use C++.

If only this had redux and router I'd be golden.

so...?

It's almost as if there are multiple people with multiple opinions here.

what do you mean? it's just me and the anonymous guy

It's pretty sad though. C++ is a garbage language but there are still uses it seems.
Could you dographics programming in rust? I guess you could, is anyone doing it?

look at piston or whatever it's called

>Should I just start learning C++ if I want to get into stuff like desktop applications or gamedev?
if you're serious about gamedev you're gonna want to learn C++ sooner or later. nothing wrong with learning the principles in other languages, but if you stick with it, as your projects/requirements increase in scale/complexity, you'll eventually find yourself gravitating towards C++

C# (.NET Core or .NET Framework, not Mono) with OpenTK (very efficient managed bindings for OpenGL and OpenAL) is by far the best (and most viable for large-ish-scale) non-C++ gamedev solution i've seen

you can do graphics programming in most languages (practically all of them have OpenGL bindings). it's just that most of them don't perform well enough overall to be viable for large-scale/AAA applications

Pretty cool, but I was thinking about something that would compete with like.. Unreal Engine.

>you can do graphics programming in most languages (practically all of them have OpenGL bindings). it's just that most of them don't perform well enough overall to be viable for large-scale/AAA applications
That's what I'm wondering - is Rust viable for large scale AAA applications? I can't think of a reason it wouldn't, but then again I also don't know anything about graphics programming.

AFAIK there aren't a lot of graphics libraries for Rust yet.

The number of fundamental problems with C++ is just overwhelming. It has so much potential but it's all pissed away on poor design choices (e.g. putting shit on the heap that doesn't need to go on the heap, lack of a good native exception handling system, no proper support for unicode, excessive verbosity everywhere)

>I can't think of a reason it wouldn't, but then again I also don't know anything about graphics programming.
assuming a straightforward binding of OpenGL's API, the graphics programming aspect would be much the same as in any other language. the primary factor as far as viability is the language itself. Rust falls short of C++ somewhat in terms of performance, but not as much as most other languages. so "large-ish" scale is certainly possible, at the very least. it may not be at the bleeding edge, but considering the honestly rather abysmal standard of technical quality in much of the AAA lately, i'm sure a well-written game in Rust or even C# could manage to technically parallel or exceed much of the current market

>AFAIK there aren't a lot of graphics libraries for Rust yet.
surely there's a simple binding for OpenGL, at least?

>putting shit on the heap that doesn't need to go on the heap
what do you mean by this?

I need a way to rewrite this so MOSS won't detect it as cheating. I can't remember anything about fucking do/while loops. Can someone convert this to a regular switch or if/else statement? I'm too much of a brainlet to learn this myself.

char progcont = NULL;
string pcode;
do {
system("payroll");
cout > setw(0) >> pcode;

switch (check(pcode)) {
case 1: manager(); break;
case 2: Hourly(); break;

case 5: menu(); break;
case 6: cout

Do-While loops execute code before evaluating the while condition. Having other people do your work will make you continue to be a brainlet, I hope you know that. The sooner you take responsibility for your actions (or in this case, inaction from not bothering to learn it), the sooner you'll not be a brainlet. Take 30 minutes to understand it, I'm sure it'll be worth it.

My program is dropping the values of all the variables after the while() loop and so it's crashing.

it's pretty simple. The loop runs once, then it checks if it should run again. In other words,

this:

do {
something = is.happening;
} while(check.if == should_continue);

is the same as:

something = is.happening;
while(check.if == should_continue) {
something = is.happening;
}

I hope that makes sense

Also, don't plagiarize code. That's a shitty thing to do

I don't think it's your values. Remember that to printf integer values, you must use "%d", not "d%".

This is the problem. Every online guide is structured like this, which tells me that it's understandable to SOMEONE. But not me. Fuck man, I just want to do Biochemistry research, but I'm being forced into a subject I have no desire or ability to learn.

>That's the thing about writing quality code. If you don't clean it up well that's no good. And if you're thinking, "oh, well that's someone else's problem", then you're bloody wrong bucko. That's something to really think about. Jonathon Blow once said that it's important to not get lost in the optimization, so you can think to yourself "okay, I can optimize my code later", or you can bloody do something about it now.

So normal while loops verify/check a condition (such as "is this value true"), then run the loop WHILE that condition is true. So, it'll continue to run until that condition is not true. Do-While loops run the loop once, before verifying ANYTHING. Then, if the condition in the while is true, it continues to loop until the condition is not true.

Ok I understood that to an extent. But how would conditions be changed?

FUCK JAVA and all the MEDIOCRE DEVELOPERS it enables. I'm so tired of being told I have to make my code accessible to somebody who isn't interested in learning anything beyond their Java degree.

>I just want to do Biochemistry research, but I'm being forced into a subject I have no desire or ability to learn.
Biochem research is heavily reliant on programming. What did you think you were going to be doing, mixing test tubes full of brightly coloured water?

Just lean the subject material. It's not even hard.

I'm already in a lab. The Biomedical Engineers and CSfags do all the programming shit. I just run the tests and the programs to get results. It may be dependent on programming, but it sure as shit isn't dependent on me doing the programming.

Okay thank you, I'll commit sudoku once this thing is done.

Think about displaying a menu to user and asking for input, then if input is not valid you repeat
So you print text like
>select 1 for carbons, 2 for proteins, 3 for fats or 0 to go fuck yourself
then you take input
then if input is not 1, 2, 3 or 0 you repeat the above

So that's basically do-while - you show the menu and wait for input before checking if there is valid input.

To do that with while you'd must first set input to invalid value.

The condition changes based on the code that you write. If your while is structured like "while(isOneHundredYet < 100)", and the loop increments the isOneHundredYet variable each time it loops (using isOneHundredYet++). If isOneHundredYet is initialized to 0, then the while loop would loop until isOneHundredYet is 100 (not less than 100).

doesn't this have a dynamic programming solution?

You have made it.

It's a difficult thing to get used to, I know, but it's a different way of thinking. First, try to think in terms of what the computer is actually doing when it runs your code:

You know how computers do stuff, right? Generally speaking, the processor receives individual steps as "instructions," which are very basic messages that tell the processor what to do (for example, an instruction could say "multiply this number by this other number"). The computer executes one instruction at a time, in chronological order.

Some instructions can tell the computer to go forward a few steps, or back a few steps. These are called "branch" instructions. These instructions are what allows if, for, while, do/while, etc.

In pic related, each black box is an instruction.
The black arrows show the way the computer would normally execute the instructions: one at a time, in order, from start to finish.
The colored arrows show where "branch" instructions tell the computer to skip forwards or backwards based on a condition.

>I don't believe in myself

I'm a 35 year old boomer so you're going to sit there and read me ranting user. Let me tell you about Lisp, now that was a real programming language, not like the so-called programming languages kids use these days like Python and JS

You've got 3, maybe 4 anons here trying to help you here. Please just keep trying and make a concerted effort to understand (not memorize) this stuff. For anything you don't understand, there are thousands of resources out there to help you. Have some confidence, you'll get it, this isn't difficult.

already in the process.
but i got side-tracked and now learning vulkan

I should mention that this is a huge generalization and that modern computers are a lot smarter than what my shitty drawing may imply. A modern computer can look ahead at instructions that it will be told to execute soon. If it finds a branch instruction, it will actually use its extra cores to run both directions that the branch can take, before the branch is even supposed to be run. That way, it already knows what the result of both ends of the branch are, and it can skip right through to the next part of the code once it gets there.

This is "speculative execution," which you might have heard of because of the "Spectre" thing with Intel and friends. Speculative execution is enabled by something called "pipelining," which is the name for the thing that allows the computer to "look ahead"
