It results in MUCH cleaner,elegant, and expressive code. Especially when working with ranges.
Although C++'s would probably use :: like Rust, so itd look gross.

>Well, one day, when I was sitting in my office, I thought of this little scheme, which would redress the balance a little. I thought ‘I wonder what would happen, if there were a language so complicated, so difficult to learn, that nobody would ever be able to swamp the market with programmers? Actually, I got some of the ideas from X10, you know, X windows. That was such a bitch of a graphics system, that it only just ran on those Sun 3/60 things.. They had all the ingredients for what I wanted. A really ridiculously complex syntax, obscure functions, and pseudo-OO structure. Even now, nobody writes raw X-windows code. Motif is the only way to go if you want to retain your sanity..

This one's real:
C++ is a horrible language. It's made more horrible by the fact that a lot
of substandard programmers use it, to the point where it's much much
easier to generate total and utter crap with it. Quite frankly, even if
the choice of C were to do *nothing* but keep the C++ programmers out,
that in itself would be a huge reason to use C.

Regardless of who says it it's completely true for anything but the simplest programs. And oop people tend to plead that there are no big programs that are done in 'good' poo. But even if this were simply developer incompetence you must ask why large oop programs aren't as easy to do as imperative programs.

Will I become a power programmer now?

>>61122762
Well when retards unironically believe it, it needs to be done.

Please help me /g/

- Been a python programmer hobby/professionally for 6 years
- Read K&R, literally too stupid to do anything right in C beyond their exercises
- Decide to learn Go, get familiar with the syntax

How do I learn all this stuff that feels naturally for me in Python?
For nearly any problem it doesn't take long to come up with a proper strategy (OOP, comprehensions, using namedtuple or enum or whatever standard library module that fits the job perfectly). In Go I have to think/google for hours and come up with what feels like a hacky solution.

Is there any way to learn the 'mindset' of a new programming language?

Reminder that real programming is never pretty and clean. Faggots who write "cute," "comfy," or "elegant" code are good programmers, but they're also smelly NEETs who sleep with dolls of little girls.
Reminder that real programming is functional, object-oriented, imperative, AND declarative, and uses recursion AND iteration, and there's no rhyme or reason, nor any other kind of decency, as to what's used when for what.
Reminder that if you don't hate your code, hate the language you work with, hate your boss, and hate your life, you're almost certainly not making anything useful.
Reminder that efficiency matters more than abstraction, readability to your superiors who are stupid and know nothing about programming matters more than either, and your little programmer fee fees and "time" are lowest possible priority.
Reminder that programming is a job. Not a hobby. Not a field of study. A fucking job.

What are you talking about? They don't give a shit about Blend. I'm not sure why the one anon keeps spamming that same screenshot in these threads.

Blend is basically a WYSIWYG GUI editor on crack for GUI frameworks like WPF, plus web stuff. It's good for what it does, but the WYSIWYG editor built-in to Visual Studio runs on the same tech and is perfectly adequate.

>>61123327
The only cringeworthy faggots here are the pathetic slobbering NEETs who actually have little enough going on in their lives that they have enough attention span left over to consider programming as something to actually enjoy.

Honestly it's cool and all to idolize and glamourize the fancy math and physics that's going on out there but you have to realize that only the genetically and economically blessed 0.001% get to do cutting edge research in pure theory. In this day and age there is no reason to not incorporate automated computations into your work. Unless you can prove your problem is undecidable you better had some sort of simulations or plots to go with it.

Incorrect.
We are not allowed to innovate because rich people are thieves and are allowed to take whatever """"""job"""""" they want for themselves so of course they'll pick something shit-easy like being an """""""""""""""""""""""idea guy."""""""""""""""""""""""
Because of corporate greed, there is literally no overlap between programming and deciding what needs to be programmed, except among the self-employed, who are basically just NEETs.

Programming is the application of useful knowledge to efficient methods of giving computers instructions.

Where the fuck do you fart, faggot?

Also, just because I get paid plenty, doesn't mean I do any sort of brown-nosing.

In fact, I insulted my way to where I am now. Most meetings are spent shitting on what other people have to say, and proposing cheaper/faster/more effective alternatives. I constantly get taken aside for being too aggressive, particularly with clients and upper management, but I produce results.

Haha lol I love toilet humor.

I've recently started learning Java as I know a lot of people who program in it and said they can get me gud job eventually.

I've gone through some online courses (CodeAcademy & SoloLearn) but they cover the basics and stop abruptly, any other tutorials start much more in depth with things that aren't covered (console, arrays, etc).

My intention is to build a portfolio of the below, but no tutorials I've found come remotely close

My goal is to make:
>Slot machine jackpot game
>Interactive gas station pump display (hold button down to roll price and multiply by liters)
>Tic Tac Toe
>Website listing for fake animal adoption agency (or something similar)

Any advice/ebooks/recommendations to get me to the point where I can attempt to make those would be greatly appreciated.

How can I fix my shit attention span

I posted yesterday at: >>61117788

tl;dr can't get game controller to work at all in SDL2, switching libraries isn't possible for this project.

In response to: >>61117930

There's not much code I have, but the code that is there should work but it's not.

case SDL_CONTROLLERDEVICEADDED:
    I_sdl_ContAdd ( event.cdevice );
    break;
case SDL_CONTROLLERDEVICEREMOVED:
    I_sdl_ContRem ( event.cdevice );
    break;
case SDL_CONTROLLERBUTTONDOWN:
case SDL_CONTROLLERBUTTONUP:
    I_sdl_ContBtn ( event.cbutton );
    break;
case SDL_CONTROLLERAXISMOTION:
    I_sdl_ContAxs ( event.caxis );
    break;

There is code from my SDL event manager, those functions don't have much in them at the moment, right now I have it so that it sets an integer to event.which.

static void    I_sdl_ContAdd ( SDL_ControllerDeviceEvent event );
static void    I_sdl_ContRem ( SDL_ControllerDeviceEvent event );
static void    I_sdl_ContBtn ( SDL_ControllerButtonEvent event );
static void    I_sdl_ContAxs ( SDL_ControllerAxisEvent event );

And I have both

SDL_Init( SDL_INIT_VIDEO )

and

SDL_InitSubSystem( SDL_INIT_GAMECONTROLLER | SDL_INIT_JOYSTICK )

called.

I even added these bits of code that I saw "might" help

SDL_GameControllerAddMappingsFromFile ( "./gamecontrollerdb.txt" );
SDL_GameControllerEventState(SDL_ENABLE);

Still can't get anything to work. Any ideas?

>>61124647
Turn off your phone, turn off your computer, remove all distractions.

>>61124677
I should add that none of the events even register in the first place. I have other events that register, but not these ones.

K&R is a shit way to learn C.
If you learn C primarily from K&R, you will write bug-ridden, memory leaking programs. You will walk away with no understanding of the edge cases you must consider in C that you wouldn't in other languages. You will learn outdated techniques.

That said, any book to learn modern C tends to read more as a reference than a book to actually learn C.

I suppose, use both K&R and Learn C the Hard Way, the latter of which focuses on safety a bit more.

Then endure 5 years of trial and error before you're actually writing good C code because no one actually gives a fuck to teach how to program C the right way. C books are either made for people who already know C and already have that 5 years of experience, or shallow as fuck books for 5 minute attention spans and are probably surprised if anyone actually finishes them.

Someone should really rewrite K&R for modern C practices.

Autism. Literally. Little autistic shits and virgins with assburgers need someway to feel superior to everyone else since there's nothing else good in their life, so they choose a language which does take good skills to program in effectively without fucking everything up, and use that they use that language as proof they're better than all the other programmers.

Anyone getting a pure CS degree or lesser in this day and age is making a mistake desu. If you want to go full tech, go into engineering. Otherwise find an application space you're interesting in (examples: bioinformatics, applied chemistry) and learn programming on the side to complement it. A programmer without an application domain in this day and age is useless coming out of university. They're a dime a dozen. And with python with C backends and similar languages lowering the barrier to entry (as companies always have done, this whole coursera push for example is designed to make the job market more competitive for the benefit of companies) as well as the cost of compute going down its easier than ever for a 10 year old to write a killer app.

Being a "programmer" is an increasingly awkward career path. Just my 2 cents. I'm not even sure who I'm replying to but I'm sure there's some HS students thinking of CS for uni here.

>Java which treat all object types implicitly as references
This.
People often say Java treats object types implicitly as pointers.
THIS IS INACCURATE. THEY ARE REFERENCES.
JAVA DOES NOT HAVE POINTERS.
Sepplesfags get confused because in their shitlang, references aren't reseatable, and the assignment operator is a member function of the object bound by the variable on which the operator is invoked.
In Java, references ARE reseatable, and the assignment operator functions ONLY to reseat a reference (except with primitives, which are reassigned by value as in sepples because they're simple and it doesn't matter).
THIS DOES NOT MAKE THEM POINTERS THEY ARE STILL REFERENCES

Learn JavaScript first.
HTML and CSS are both declarative presentation languages. They aren't really programming languages, because a programming language is a language for defining how something behaves, and HTML and CSS are only for defining what information things contain and how that information should look, respectively.
JavaScript would be a good first real programming language for you because it exists specifically to dictate behavior to be added to otherwise behavior-less webpages, which are applications whose most basic inner workings you're already familiar with.
Once you understand how a programming language works, as distinguished from a markup language or other kind of presentation language, I'd suggest trying your hand at C.

Java is used largely for desktop applications and Android applications, while Javascript is used in web browsers to add interactivity to websites.

Not that guy. But how do I read the nonsense people write in C#/Java as desktop apps? Their program seem so incredibly difficult to extend well to me. For instance, all I want to do is queue downloads in case the replay isn't ready and add a UI notifier for that:
https://bitbucket.org/ZuLuuuuuu/reflex-replay-helper
I've opened this and had a good read and I'm seeing that there's an obvious place to insert the code that handles my case (since the exception it throws for when the replay isn't available is just a simple error message).

If this were my program I'd just add a system (if I don't already have one) that lets me defer actions. I'd add an action, if it checks again and it fails it'll just add the same action again. Super clean system with no problems.

Here everything seems completely baked into the UI though. I can't find a single update loop that handles rendering the UI or updating state. How do I even have it make intelligent decisions at all? It has no systems for that at all. It's a simple UI for downloading and launching a process but it's so much code just for that.
I'm not a C# programmer, I've dabbled. But these systems just seem impossible to work with. Why you'd put all your shit in the UI like that is beyond me. You couldn't even give users a CLI without rewriting the whole thing.

Is this normal or is it not? Because everything I look at has similar issues. It has put me off so many times and I've always just rewritten shit instead because it's so much easier. This application doesn't do very much. It's easy to replicate and I'm considering doing that not just for this feature but because it'd let me do much more (like automatic downloads and the likes). But it feels like such a waste every time even if it serves me quite well.

The std::sort uses, in the simplest case, a pair of random access iterators on a container. The default sort uses operator< to compare, but you can specify the comparator with an additional argument.
Here's an example of how to use the basic case:

#include <random>
#include <algorithm>
#include <cstdio>

int main()
{
    std::random_device rd;
    std::mt19937 gen(rd());
    std::uniform_int_distribution<> dis(0, 10000);

    std::vector<int> v(100);
    std::generate(v.begin(), v.end(), [&]() { return dis(gen); });

    std::sort(v.begin(), v.end());

    for (auto e : v) printf("%d\n", e);
    return 0;
}

>mingw is a port of gcc tho

I'm not an expert on C compilers, but even if mingw is a port it might not be based on the latest build of gcc. I got both compilers just off Ubuntu's default repo, so who knows how up to date either are.

It's always seemed like a baby language, not even a language, just a syntax for small things, but I keep getting stumped by things and I'm not sure if it's because SQL is bullshit or because I'm an awful programmer

It is a baby language, with a very specific use, but it's quite good for that use. It's a lot like regular expressions in that sense.

I bet you've never even seen a declarative language before.

You may be after a .jar file. Look up how to make a Java archive.
Or you're looking to pack the JVM with the program and actually get a semi-portable executable. There's ways to do it yourself but pajeets recommend you use one of their cruddy solutions. I suspect that's actually what you want.

>>61127587
Implicit variables, macros that aren't documented very well, a very confusing standard library, lots of not-always-clear differences between minor versions
Not an entirely bad language, and it is better than Java (at least Java 7) by a longshot, but I prefer Clojure.

Things that suck are replaced by things that don't suck. There are some exceptions, where something has been mediocre enough that no better replacement has come along.
But if you had to create a language for querying a database, I'm not sure what you could do that would be wildly different from SQL.

How do you write a windows/linux driver to your newly invented device?

Trying to figure out how to implement acceleration and deceleration using vectors in 3D. I don't know how to account for positive and negative axis values to apply friction to.

Anyone got any ideas? /agdg/ are useless when it comes to math.

Correct.

Look at what was available before. We don't have to use TCL or VB or Basic. Java 9 is miles better than Java 1 or 2. C++14 is miles better than C++98 or whatever it was called. Python 3 is even marginally better than Python 2.

this is the textbook you're looking for

Time to start reading vector math then.

(i, j, k) - (x, y, z) = (i - x, j - y, k - z)

>>61127774
Common way to do it is to just apply friction as a function of the speed vector.
And acceleration/deceleration, that's pretty obviously just a value you use to modify your vector.
Read physics if you're after realism.

>>61127802
I love the covers on Taylor's books. His error text has a railroad train running out of a smashed wall.

>>61127774
just use bullet3d, box2d or something similar. if you ask such things you are clearly not up to the task to write your own physics engine.

>>61127802
Except game physics shouldn't always be realistic. Not advising against lrning physics, just that sometimes, a 10000 kg player character makes total sense, gameplay-wise.

>>61127811
Vectors are ezpz.

What are some really obscure math operations and or geometric systems? It's not obscure but things like tropical geometry comes to mind. It's just an odd replacement of operators and it actually has a use.

I want to learn more.

>>61127868
quaternions

>>61127850
That's fine, and you can tweak and adjust things as you see fit. But if the "friction" and "acceleration" and "vectors" and "three axis coordinate system" are the words that I know them as, then you are referring to things which you can understand with the helpful text and exercises given by Taylor in that text

>>61127845
Most video games don't use physically based systems for simulation simply because they're not that sort of game.
Box2d can be used to simulate particles well. It's inefficient when used like that and a custom system is easily better but it can be done simply for ease of use.

I suspect anon has very specific requirements since she's asking about how to do it herself. So just using a library might not be the best.
It's good that you mention it though but you're assuming too much about the situation.

>>61127868
Clifford algebras (also called geometric algebra)
Getting into topology can open some great doors along those lines, especially defining interesting topologies (with or without interesting distance metrics)

>>61127904
Yeah well I know those. I wouldn't consider them that obscure either. But thanks for mentioning them. I certainly would like to know of them if I didn't.

>>61127868
Does Non-classical logic count? Your criteria is quite vague.

>>61127812
Yeah I've tried that, but I don't know how to apply it to a value that could either be positive or negative. The friction will have to either have to add or subtract from the velocity.
>>61127845
I'm not making a game to make money, I want to learn how to make them. I wouldn't learn anything if I used some proprietary physics engine.

>>61127931
It is vague. But that's because I really don't know what I'm after. So it's hard to be specific. I'm not looking to solve a problem. I just want to learn about something cool.
>>61127927
I'll look into it.

Just add up the values. If it's positive it all adds up, if it's negative it negates it.

>>61127945
The simplest way to do friction would be to have it be a multiplier on the speed based on the speed.
An example:
https://github.com/ecbambrick/ThrustVector/blob/master/src/physics.lua

It's a simple system and can extended easily.

both are open source. and you might find that you in for more than you wanted when it comes to collision detection, real time collision, intersections and funny things like GJK Algorithm, penetration depth and other stuff. but you will learn a lot.

If you have done a CS degree, you might not have hit on group theory or abstract algebra in general. There is loads of good stuff there but somehow it isn't seen as a fundamental topic except for math students. Just some basic familiarity with groups, and playing around with a few (like the movements of a Rubix cube for a fun example) is a pretty easy task and occasionally helpful
