Hello fellow D programmers
>>55145663
Usually you don't implement the entire thing in OpenGL. What you're looking for sounds like a 3D engine example which uses thinly wrapped OpenGL or something. Because you'd have to define the world inside a fragment shader or something. And that's pretty much only convenient using raymarching (which is cool, you can do that). But it's not common. I wouldn't know where you'd find that.

Wanted you guys opinion.
I am modeling a database that I have 2 tables, one for stock items and other for sales and I am pretty sure I should have a relationship between them. Should it be a many to many (for both items/sales and sales/items) or should it be many to many (item/sales) and one to many (sales to items)?
Please be gentle.
>>55146700

XML is lovely at times, a user can crack it open and just "change something", save it and it "just works".
If you know XPath or XSLT and have a transformer available then XML is turing complete and it's AMAZING.

Just lost my job web deving (company collapsed). What should I develop to make some cash short term?
Web systems I was working on used ASPX and CSS with either VB.NET or C# backend, using SQL for database shit.
Also know C and C++ from college days, but probably more than a little rusty now.
So I have (C++)std::string that is
"m:.word1,9,12"
How can I seperate out the string to put into my list like this, or add it to a map? everything before the ':' is a variable so it could me "ne:.word" or "bubble:.word"vector.push_back(1); //by parsing 1 from the string
vector.push_back(9); //by parsing 9 from the string
vector.push_back(12);
I'm just having alot of trouble trying to parse out these integer values. Basically my only idea if delete everything before the first integer "m:.word" and then use the , as a token position to get substr of each variable but even that's a bit weird for me to get.

You have two tables, and you write one number to each table.
Then you read it into each direction.

I'll explain.
So you know how all the games that are made with some `real` language like C++ and some engine. Then later they bolt on Lua as the scripting language for the UI.
Well... when you're in the `enterprise` all you really care about is the database and document generation. So you build you system in Java / C# and it's got Oracle / SqlServer and all the documents get output as XML. The scripting language you bolt on so that your techie users can get anything done is XSLT.
XSLT is amazing in this environment because you can just bolt the transform step onto the end of your document generation and tell your enterprise customers to work it out themselves... or they will pay you services money to fix it for them.
So yeah, literally _any_ scripting language is more fun to use than XSLT.
But... in the enterprise we don't like to have people running Python interpreters or Lisp or Perl or Brainfuck or anytihng.
XSLT is really limiting (part of why I like it) which makes it really easy to stop users shooting themselves in the foot.
... but it's not limiting to the point of stopping you actually getting work done. It's turing complete. There's _one_ good way to do everything which limits the amount of fucking around people can do.

English isn't my main language too but, as far as I know, a stock is basically what the items that a store, for example, have to sell.

>How does it make the language more portable?
It allows the language to run efficiently on more architectures and implementations. An implementation can use something which makes sense for their platform, instead of trying to emulate some other crap.
Integer sizes are the most obvious example, where C can easily run on non-8bit addressed computers, while many other "modern" languages can not. It extends to far more than just this though.
>I'm buttblasted about standard-defined functions having implementation-defined behaviour
What specifically? Ignoring locale-related and maybe some floating point-related shit, I can't really think of much.
>>55148737
>It helps make the language more portable
The only two reasonable interpretations for this sentence are "It helps make programs written in the language more portable" and "It helps the language be supported on more platforms". Neither of these is achieved by having implementation defined behaviour in the language standard.
>Anyhow, could you point one of the functions that you have in mind?
Sure, just check the clusterfuck that is the majority of the signal family of functions (of which only signal is standard).
>>55148774

It helps the language to sort of run "almost the same" on a lot of computer platforms. Remember, every in Unix and C land is sort of handwavy and duct taped together. This was not that big of a problem in the 70's, when programs where text oriented and quite small. C is a makeshift language and well past its sell by date.

I'm not going to get into the huge argument that this would eventually lead into. I hope it suffices to say that:
- There aren't those many non-8bit-multiple addressed CPUs
- If you're writing a program for a non-8bit-multiple addressed CPU, you're probably not writing it to be portable anyway
- Maybe instead of fucking up the standard for everyone, they should just make a sane standard for the XXI century and let "weird" implementations break it anyway (which they're probably already doing)
Your arguments are fallacious and regurgitated from StackOverflow.

>>55148840
But the problem is exactly that. Running "almost the same" is a huge potential source of bugs. An awfully huge potential source of bugs. I'd rather have my compiler outright reject 10% of my program than have 10% of my program silently being a possible source of bugs.

What family of functions?
I'm writing basically a "report" system in python, gui and all. I have a MariaDB/MySQL server hosted somewhere else, and all I need this python program to do is add new records, edit old ones, and view all records for a specific UID.
My question is, how do I make a separate login page with Tkinter and one for the actual functions? Like the login page just has two labels and two entries and a "login button", then I'd like it to close upon successful login and open a new window which actually displays potential functions.
How do I make it do this? Specifically close and open a new one? StackOverflow told me to have both of them but the login button "hides" the original screen and then the actual function screen gets unhidden. There's gotta be a better way though, right?
>>55148887
>Running "almost the same" is a huge potential source of bugs.
Of course it is, but it is also the reason why C is so popular.
What's harder? To make a systems' language that ensures that every program runs correctly on every platform or to make a systems' language that kind of works for most people RIGHT NOW and then sets computing back in the dark ages?
>>55148774
>Neither of these is achieved by having implementation defined behaviour in the language standard.
Except you are wrong.
>of which only signal is standard
This has nothing to do with implementation defined behaviour. It has to do with other standards adding more, try again.

>- There aren't those many non-8bit-multiple addressed CPUs
And?

Is it better practice to initialize certain variables outside of nested loops so that it won't be initialized n amount of times in the loops?
For example:method()

{
int a do stuff
int b does stuff
}
}
}
}
vs.method()

In principle, yes. However, 1) the cost of stack allocation and deallocation is very small; and 2) your compiler will almost certainly optimise it for you. So do whatever you think is more readable.

Started learning C++(thenewboston, is this yt good for learning?, also programming knowledge is abs shit a german guy with a pajeeth accent does the show) and I bought a book for it.
I use qt creator for c++ and visual studio.
>>55150548
>is this yt good for learning?
no
>>55150551
> browsing stackoverload and its buddies are no better
The book I found is very good but outdated. Book is from around the 80's but it is good.(It is a non-English book so I won't tell the name)
>>55150576
This is like... pre-standard C++. Just go get the book from the creator.
Why do you want to learn C++ anyway? Especially considering that you already know C#.
And why the hell do you use windows?
>>55150588
Friend started a project where we create a social something app for group projects and we are using C++ for it.
Visual Studio I think the most comfy IDE I have ever used and it would be hard to lose it so I use it inside a Virtual Machine.
The book I told about is from the uni (ELTE).
QtCreator is similar and it is actually pretty good.
>>55150329
add them and divide by two dumbass
>>55150642
QtCreator is very fine indeed.
As for the book I really suggest you check http://www.stroustrup.com/4th.html

Because I'm using Racket, you silly.
Lua is a pretty cool language.

c++ member pointer things are neatclass foo { public:
foo(int i):i{i}{};
void print() { std::cout << i << '\n'; }
int i;
}
int main() {
foo f(4)
void(foo::* fn)() = &foo::print;
(f.*fn)();

There are no scripting languages,
>>55150322
Is stack allocation of arrays also very small? Much smaller than malloc?
>>55151002
its pretty ugly. you can use std::mem_fn instead though which is a bit nicer.auto f = foo(4);
auto fn = std::mem_fn(&foo::print);
fn(f);

Is inventory a vector?
>>55148451
>If I don't have the return statement, the code gets stuck, looping forever. Why does it do that?

What programming language is that
>>55148451
Ask your favorite programming literate anything.
>>55151156
I would but she's not here
>>55150955
forgive my ignorance, but what sort of dataset are you loading into memory that is taking up 11GB?
>>55148451
Looks like java (though it could be some variant of C or frankly any number of languages).
Evaluate inventory.size(). It may be slightly different than what you are expecting it to be (an integer).
It may be that whatever optimization logic your IDE is using may be tripping over itself (though this seems fairly trivial).
Also, the return statement there is interrupting the for loop and two if statements to exit the class/subroutine/function and may prove to be inefficient, depending on the frequency that this logic is being called that may or may not be relevant.
Lastly, why don't you have a comparative in your first if statement? Depending on the language and IDE if inv is a boolean the logic may work but that could potentially cause some oddities (like always being true every time it checks it even if inv evaluates as false).
>>55151281
well they are ~4.6M rows x35 fields and take 1GB on disk, yet 11GB in ram when loaded by java.
>>55151327
Looks like C++.

Cute girl, but what does she have to do with programming?
Why haven't you rewritten your logging aggregator in Golang yet? Do you enjoy dedicating a whole server just to that task? Do you really think your shitty scripting language deserves all of these glorious cores?

Do they drug test programmers
>>55151680
Only menial and government (i.e., menial) jobs drug test.
Good luck

>>55151597
>learn a superset of an autistic language made by freetards over the much more popular and better-supported language used by people with actual jobs
>>55151680
Not usually, but many places perform drug tests when you are hired and maintain the right require you to perform a drug test with no notice.
Having done programing while sick and on meds, I really can't recommend it.
Logic stoped working in my head and I hard coded everything. Then I could remember what it was I was trying to achieve and went and took a nap (I was already at home). Then when I came down off the meds and wasn't sick anymore I had to scrap hundreds of lines of code because it was useless.
>>55151737
wtf were you sick with, that you had to take mind-altering medication?
Why is there no web browser that was designed with Unix-philosophy?

Allocating on the stack requires nothing but decreasing the stack pointer (which is always in a register). Stack memory is fast.
Also, >>55150305 I'm not 100% sure on this, but I'm pretty sure all local variables in a function (regardless of where they're defined in the C code) are going to be initialized in the beginning of the function anyway.
>>55151845
>designed with Unix-philosoph
Computers don't work that way.
Anyone have any suggestions for a project I could do to start learning Rust? I'm already experienced in programming, so I'm looking for something at least somewhat substantial.
>>55150322
>stack allocation and deallocation
>>55151063
>stack allocation of arrays
no such thing in C
>>55151853
>pretty sure
not by a long shot
>>55151845
Because that would be relatively inefficient for something that is rather resource intensive.
>>55151903
>not by a long shot
Can you elaborate on this? I don't ever remember seeing a disassembly where all local variables aren't done by a "sub esp, 0xSize" (Size being of course whatever the needed size is).

>wtf were you sick with, that you had to take mind-altering medication?
I had a sever nasal infection that migrated to my ear.
I was on a decongestant (Sudafed) to relieve the blockage, a prescription anti-biotic to fight the infection, and a painkiller (nothing hard like morphine but it was more potent than over the counter) for the ear ache caused by the buildup of fluid.
The Sudafed alone got me high as a kite. The painkiller and, to a less extent, the anti-biotic were just the proverbial icing on the cake of my 'elevated' state.

God damn it man stop this bullshit. It is too late to be trying to make coherent thoughts.
>>55151976
first, "sub esp, 0xSize" is not C
second, initialization has a defined meaning in C
third, entertaining your delusion that "C == x86 asm", automatic variables can also be placed in registers
>>55152035
yeah -- I am enjoying the repeated (You)s, but it seems like you need some rest, friend
>>55152067
I agree that "automatic lifetime" != "stack allocated" and people need to be careful how they think of it, but I feel that you're being a little bit too pedantic for this conversation.
>>55151845
Because Unix philosophy is shit.
>>55151458
Haskell is 1.8 GB big duh.
>>55152067
I meant that what's written in C code is somewhat "irrelevant" as in the end it gets compiled to the platform's assembly (didn't mean to insinuate that it's always x86), but you're right on the variables that exist in registers only though, didn't think of that. My original point was that local variables on the stack are created in the beginning of the function (even if they're declared somewhere else in C and assuming they're not inside a register).
>>55152239
>local variables on the stack are created in the beginning of the function
not necessarily https://godbolt.org/g/tcsnp7
>>55152207
No it isn't. Haskell is a programming language, not something you can install. That's like saying C++ is 0.3GB big.
>>55151845
Make one
>>55152424
'Haskell' has become synonymous with 'GHC'.
>>55152424
>That's like saying C++ is 0.3GB big.
More like saying perl is xGB big.

what is the best book for learning Qt?

Not the guy you are replying to. Out of sheer curiosity I went to the qt documentation page just know and where the hell would someone start? This stuff is what I fear the most a bunch of classes, libraries, namespaces and paradoxically you are supposed to know what your are searching before you even find it. Same stuff happened to me when I was doing a bit of work in java. How do I word this right, if you are not aware that there exists a module/class/library that does what you want, you are not even gonna search for it since, you know, you are not aware it exists.
C is a shit language. Prove me wrong.

Oh look, it's that "argument" of absolutely no substance again.
