I'm working on a game. But I'm stuck doing unity tutorials for now.

I want to design so bad but sitting down to learn from videos just kills my motivation. I can "design" all day, but sitting down for a 20-60 minute video tutorial totally ends my progress for the day. :/

Why does storing floating point numbers in a database always store numbers which are off? I've tried double and long double, but still get weird stuff like 1.23365 gets stored in the database as 1.2336499999999999

why would you assume he didn't already know this
not him but i am also a game designer who dislikes having to do hard work
and i should certainly know how i feel about hard work because my dad was really abusive and it was hard work just to live in the same house as him

>>61033476
Right but that's not the problem, its something to do with what I'm doing because when I load the database directly it stores the numbers correctly but when I insert through C++ it stores these.

DRY philosophy is trash

Finished writing my kickstart script so provisioning all my servers will be less tedious now. Wish there was a way to ID network interfaces non-interactively.

Don't laugh:

On the surface it looks like a shitty Python clone,but it has so many crazy features and the meta programming is the best I've ever seen in any language.

>>61034222
Practical programming languages aren't hard to use

my boss has pretty much refused to give us all of the project requirements up front (because he doesn't even know what he wants) so every time my boss proposes a new feature it requires a huge rewrite of the whole system because we had absolutely no idea that he wanted that feature

so i'm doing one of those rewrites.

i've been putting applications in everywhere with no calls.

>>61034166

>>61033625

How so?

It's pretty smart to know where to look when something doesn't work. Also code duplication is a bad thing.

Of course every "pattern" can be misused. But it's similar to OOP, MVC and GoF stuff: know when to use it and when NOT to use it, and you'll be a good programmer.

You're being paid to write software.
The fact that you're complaining about throwing out work means you're becoming attached to software that you're being paid to write, it's NOT yours, deal with it.
If your company wants to keep wasting money and developer time rewriting the application over and over again, let them, it's not your problem because it's not your code.

what do you guys think of j, apl, and other array languages?

>>61034309
yeah when my boss wants new features to be rolled out on a weekly basis, each requiring a complete rewrite of the entire front-end of 3 different websites, and i'm the only one working, it's a bit stressful.

when i say i'm the only one working, i do mean that i am literally the only person employed on the dev team at this company. i do not have a single coworker until the end of august.

so i'd say i have the right to complain about throwing out work when even more work keeps getting piled on. i also have the right to tell you to go fuck yourself. deal with it.

>>61034330
I've only messed around with J for a few hours and it was pretty fun.

>>61034305
>know when to use it and when NOT to use it, and you'll be a good programmer
pretty much, but DRY is being sold as a holy grail, every book and novice tutorial has it right after helloworld, when in reality it's easier, faster and less bug-prone/more future-proof to write multiple special cases vs one that tries to cater to everything.

>>61034389
It's your own fucking fault if you're letting work pile up exponentially because you're too autistic to communicate to your boss that every feature addition means a total rewrite.
If you're really the only dev, they're not going to fire you because it would take longer to hire someone and get them up to speed.

>>61034271

What's your point?
That you can abuse things?

"Method missing" is pretty dark magic, but you can use it for some special purposes.
A thing that comes to mind is an object that delegates calls to a sub object (as "proxy" or "adapter")..

Or if you want to build a testing suite, it can be pretty useful.


>>61034291

It is far from smelly. It is a very good engineered and designed language.


The greatest things about Ruby is that it's such a versatile language. Super comfy for scripting and web stuff is crazy easy. Not only websites, but you can make a webscraper or an API in no time.

But yeah, Python or even Perl can do this, right?

What makes Ruby really stand out is that it's basically "building material". It's pretty much an OOP version of LISP.

You can use it and simply make you own domain specific language. Look at RSpec, Chef, Puppet, Rails or Metasploit to know what I mean..

>>61034453
i did not help create the initial product. i was hired when they had one working site and were expanding to 3. then all the other devs left for internships elsewhere for the summer.

up until now, most of the new features were just small additions that didn't require any rewriting. anytime my boss proposed a feature that did require a significant rewrite, my coworkers would tell him it wouldn't work yet, and put it off until later. well, it's later now, and i'm having to do the rewrites.

all of this would have been avoided if my boss knew what the hell he wanted, and gave us the full list of requirements and features that he wanted the sites to have, instead of giving us this stream of information over time.

>>61034550
you can also use method_missing to create a class that implicitly has attr_accessor for all possible member variables

>>61034437

Of course.

I do not trust any "hoyl grail" anymore, when it comes to programming.

>>61034259
I don't do tcp, ask in their IRC

Is GDI+ still a good option for custom controls in C#? I'm looking into making a syntax-highlighted text box component and I don't want to build it off a TextBox/RTB for performance's sake.

How would you go about doing 2D platformer collision between an entity and the world (static tiles, dont move) and solid entities (most likely static but can move).

There AABB, but how do you ease the load of the program so that it only looks in the radius around the entity?

Using horizontal movement for the question, flipping row and column around would be for vertical movement I suppose.

Do you go down every pixel row, and on each row, check so many column pixels in the given direction and skip checking collision if it is "out of bounds"?

It could, but it's needless if the world is tiled.
>how difficult is it to implement a quad tree?
Not that difficult at all. It's pretty much just a binary search tree, except that the keys are coordinates, and accordingly the key comparisons are done on two axes instead of one (hence why four quadrants are necessary instead of two halves).

I'm reading the Practical Objected-Oriented Design in Ruby book, and I'm trying to solve a problem in terms of messages between objects.

It's C#.
I need to create a Windows Service that's gonna run once every hour.
It should get messages from an IBM MQ query, save the message to a SQL database, and then delete the respective message from the query if it has been successfully written to the database.
In case of any errors, it should log the error to the Windows' Event Log and send an e-mail.

I thought of these interfaces:

interface IRepository<IMessage> {
    IMessage Get();
    bool Save(IMessage message);
    void Delete(IMessage message);
}

IBM MQ and SQL should implement the same interface.

interface ILogger {
    void LogError(string message);
}

EmailSender and EventLogger should implement the same interface.

I'm unsure how to design this better. Any tips?
I'd also like to use manual Dependency Injection, and because of that I'm unsure on what object should have knowledge of the concrete classes.

I can't fathom why people dislike Pepe beyond that. Fucking redditors and normies can "repost the funny pics" all they like but because their website is NOT anonymous and is NOT ephemeral in nature they'll never understand the true significance of memes that have taken the form of being almost living idols/gods. Asuka might as well be a real girl that exists, she has a personality that extends beyond evangelion as an immortal part of the sites history and character because of her association to Moot and the shitposting between reifags and her. Pepe exists at this level too. Dumb frogposter is something that exists only on 4chan, the person posting an image of an angry Pepe reeeing is taking the mask of a dumb frogposter for that post. The person posting a picture of what appears to be THE GRINCH IN A MASK HOLDING A GUN is taking the persona of a fed up Beta ready for the uprising, and a Pepe directly inhaling memes while crying is clearly an anon taking the mask of a poster whose life is drowning in memes so much that he doesn't even know what he's escaping from anymore.

This type of mask donning associated with reaction images is a natural part of the site that basically no other web community shares. If you just want blocks of text with highly detailed hobbyist/topic discussion perhaps I'd advise you to see a development forum instead of posting on an anonymous Indonesian sculpting bazaar.

They died naturally. Maybe Pepe will die too someday. Fags getting buttmad and posting "dumb frogposter" won't kill Pepe though. Personally I'm hoping Apu will usurp Pepe. I find the fact that some retards can't even tell the difference between Apu and Pepe amusing. He's the natural evolution, the alterations are a mixture of accepting being a "dumb frogposter" eg, him being retarded, and separating from reddits missuse of Pepe.

>>61036794
a miniskirt so show off your shaved legs

>>61036800
The application window is only open for a month, march to april or something, but it's good to prepare before that. Basically you're getting paid to independently develop for an open source org but you have a mentor you can consult. You have to submit a detailed project proposal, outlining what you want to do and the timeframe in which you'll do it. It's not hard to get into but it really helps to talk to the host organization and convince them that they need what you want to do and it's worth mentoring you. Communicate with them and write a detailed plan as if you've already been hired to do it and it's bound to succeed.

I'm coding some math stuff for a computer algebra system and my mentor reviews my code, helps me decide what methods are most important, and gives me tips on how to speed things up.

So, I just want to rant.
I am working part time, and was dumb enough to do too many classes.
Now it bites me in the ass.
We have assignments on Java, some mandatory, others not.
I have no time for the non-mandatory assignments, even though they would help me a lot in getting to understand the programming language and thus help me in getting done with the rated assignments much more comfortable and easier, since I get the experience of coding.
I have not the time, it sucks.
Or in more concise words: I crashed down and burned two years ago and I am still getting back to myself after admitting defeat and getting treatment last summer.
I seem to have a huge palate of issues hindering my development as a human being and in hindsight, as a programmer.
What do I do in this case?
I am gonna spend 6 hours a day with the use of the pomodoro technique in order to not let my brain turn to mush and get this assignment done until the next deadline on tuesday.
Hopefully I can get in enough to finish that shit.

Take this advice >>61034285
but keep in mind that's not true for everyone, while most people do well with books some do better with lectures. Everyone learns differently and there's a lot of methods, paces, and driving factors.

I personally do well with lectures, but do poorly with dense books, somehow I do much better with hypermedia though, I think it's less the hyper aspect and more the layout of modern web pages compared to typical textbooks, no physical pages gives you a lot of freedom to layout the content in a more palatable(subjective) way.

All that said, it's very important that you find out what works for you then seek out resources for the field you're interested in. There's no sense going to lectures if you're deaf, no sense buying books if you're blind, you have to find what works for you specifically.

And? it answers his question, bindings to a graphics and audio library, which SDL2 is.

>You are aware that this is retarded, right?
Nope, sorry. But C++'s expressiveness allows the compiler to optimize C++ programs better than C programs.
C++ is either faster, or the same speed, but never slower than C.

>inb4 muh virtual methods
They cost the same in C.

>>61039893
>>61039907
Not him but in the real life C++ is often faster than idiomatic C because of templates, and it's just as fast in the worst case. That's not surprising considering both languages use the same optimizations and code generators.

It does not mean that it has to be you dumb fuck, "compiled" is not a property of the language, stop talking about shit you have no idea about.

>And?
It's not a C++-only feature, SDL2 (other than the fact that it's shit) is NOT written in C++, it is written in C and can be used by every single language that can call C functions (literally every useful language).

There's a big difference between languages that are designed to be interpreted and languages that are designed to be compiled.
If you think this is stupid, then you are stupid if you honestly think Python was not designed to be interpreted.
C++ is designed to be compiled, fucking idiot.

>It's not a C++-only feature, SDL2 (other than the fact that it's shit) is NOT written in C++, it is written in C and can be used by every single language that can call C functions (literally every useful language).
Yes, fucking and? I'm fully aware of that, retard. That's not the fucking point.
Remember that most of C is valid C++ too, so it's completely fine to list SDL2. In fact his question was BINDINGS, and SDL2 certainly has bindings.

>A proper C compiler would be able to optimise both C and C++ the same way.
Is GCC a proper compiler? what about LLVM? What is a proper compiler to you?
Because both GCC and LLVM can optimize C++ better than C.

Any Lisp implementation still has to support eval-ing a string from user input at any time, making any attempt to be "static" laughable, it's basically over-engineered python.

No, bad programmers lead to horrible design decisions, producing stupid, inefficient code. There is just a much stupid, inefficient C code out there.

>Blub paradox.
Exactly what happens to C++ programmers. They use this cancerous bullshit and try to defend it instead of moving to a proper language with type inference and parametric polymorphism.

>Because both GCC and LLVM can optimize C++ better than C.
Not too long ago a head developer of GCC said that the C subset of C++ has exactly the same speed as the C++ subset of C on GCC. Are you claiming that he is lying?

>Remember that most of C is valid C++ too
Until you do a malloc, lol.

C++ can be compiled and can be interpreted. There are no interpreted and compiled languages as this is an implementation properties you niggerface.

Having a slightly weaker type system for type inference is worth the trade-off.

You do realize none of the examples pass strings to eval, right?

>>61040071
Yes, in gcc and clang qsort is slower than std::sort, so what? It makes no point about the language per se, only the implementations.

Irrelevant, I'm not a dependent types advocate.
When you'll realize type systems exist to help the programmer make less mistakes, having the compiler hide your fuck-ups will become way less interesting.

No, I'm claiming that the C++ parts of C++ are more efficient than the behavioral C equivalent.

>Until you do a malloc, lol.
You mean auto coercing void pointers, which is a bad thing anyway.
malloc works fine, I used it quite a few times in C++ code, although you shouldn't.

>For literally every language.
Including C++. What point are you trying to make exactly? I'm just answering the original question.

>C++ can be compiled and can be interpreted. There are no interpreted and compiled languages as this is an implementation properties you niggerface.
Yep, you are definitely retarded.
No point in arguing with you anymore.

I'm sorry, but if you believe that interpreted vs compiled are not considered in the design phase of a language, then you are severely retarded. You don't deserve C.

>>61040090
No it's not, fucking retard.

>>61040121
>only the implementations.
It says something when two competing implementations produce about the same results.
It says something about the expressiveness of C++ vs C.
It suggests that C++'s expressiveness makes it easier to optimize, which makes sense when you think about it, if you're not a completely braindead Ctard blub.

>>61040146
>No it's not, fucking retard.
"More" features is not "better" when said "more" goes against what type systems stand for in the first place.

I have no idea why you are arguing, every lisp implementation has to support REPL at any point. Even if it's a compiler, it still has to bundle the entire evaluator with your code just in case. And it can't possibly generate fully specialized code because of the possibility you're gonna inject new code what inserts a string in a list of ints.

>>61040164
>"More" features is not "better"
Never said that, and I agree with you.
I only like more features when said features are good.

>when said "more" goes against what type systems stand for in the first place.
Huh? type inference breaks none of that.
If you think type systems are about explicitly typing out the typename, you're wrong.
If you think type inference is dynamic typing, you're a fucking idiot.
All type inference is, is inferring the type of something from context, such as the return type of a function or expression.

It also greatly helps in generic contexts.

>>61040146
>No, I'm claiming that the C++ parts of C++ are more efficient than the behavioral C equivalent.
You will need to prove it.

>inb4 shitty benchmarks
You will need to prove that independently of any implementation the C++ parts of C++ can be optimised better than C.

>You mean auto coercing void pointers, which is a bad thing anyway.
Nice damage control, carposter.

>Yep, you are definitely retarded.
>No point in arguing with you anymore.
Losing the argument?

>>61040161
>It says something when two competing implementations produce about the same results.
That whatever algorithm they use to optimise std::sort (probably the default template algorithm) is better than whatever algorithm they use to optimise qsort (probably the default function-calling algorithm).

>It says something about the expressiveness of C++ vs C.
No, you are a retard if you think so. See above.

>It suggests that C++'s expressiveness makes it easier to optimize
No, it just suggests that they do not optimise C function calls as much as the templates.

What? Having dependent types doesn't affect inference for non-dependent language fragment.
