>a decent C++ alternative
Literally any other language. Java, PHP, Javascript.

>>58262424
This is a good idea.

Too many languages are being designed that simply repeat the mistakes of the past. A new language should be an improvement, not a step backward. To that end, let's create a list of features that any new language must have. If it doesn't have everything on the list, it ought not to be made.

Here's a starting point:

>Static typing
>Sum and product types, with support for generic programming
>Higher-kinded types
>Higher-rank types
>Totality and purity annotations and checking
>No null
>Type inference
>Tail call optimization

They should have done it years ago; it's probably too late now. Another useless language with countless man-hours of wasted effort behind it.

Maybe, just fucking maybe, programming language designers should listen to the PLT people instead of deciding "hurr it's all academic nonsense it's not relevant to real programmers" and later wondering why their language isn't working.

to avoid having a bunch of random code style unrelated stuff in my commits, i saved the large code style refactor for the end when i was done implementing whatever i needed but it feels like it just hides any meaningful history that could have been seen at a glance, like pic related

it's probably fine but does anyone deal with it

>>58262767
the last commits i make to a project are always small miscellaneous tweaks. they don't really fit very nicely together, so taking a look at my project history could probably give someone the impression that my commit habits are scattered and structureless.

the only alternative is to gather them into one commit and tag it 'misc. tweaks', which is a pretty shitty commit message.

The following code keeps failing with "Error reading from datastream"

std::vector<uint8_t> wav_data =
    tv_audio_get_wav_data(audio);
SDL_RWops *rw =

        wav_data.data(),
        wav_data.size());
Mix_Chunk *chunk =
    Mix_LoadWAV_RW(rw, 1);

>Static typing
Fairly standard for most compiled languages.

>Sum and product types, with support for generic programming
Translated into C++ terms -- tagged unions, structs, and templates.

>Higher-kinded types
>Higher-rank types
I know that one of these is equivalent to template template types, and do not know what the other is.

>Totality and purity annotations and checking
Purity should be optional, ideally.

>No null
This necessarily implies that raw pointers are impossible, and therefore while we will be using a compiled language, it will not be a systems language. Not suitable for replacing C, C++, Rust, or Ada (or D with the garbage collector turned off), it may be suitable for replacing Haskell.

>Type inference
>Tail call optimization
These should be implemented in pretty much every language.

>>58262961
tv_audio_wave just adds the data to the end of the std::vector

>>58262991
>80-col rule
Yeah, that rule only works if you're deliberately avoiding unnecessary nesting.
I prefer to use the soft-80, hard-100 rule:
Try to keep it under 80, but if it hurts readability to split the line there, you can go over. You must not go over 100 at all, though.

The key point being the parametric nature of the parameter. You aren't just passing a "template instantiation", you're passing a parametrically polymorphic function.

>Totality and purity annotations and checking
>Purity should be optional, ideally.
That's what he means.

We assume that he's advocating the same handling of totality and purity in this sentence. Since he's referred to them as annotations, it implies the possibility of the absence of these features. Furthermore, if he were saying that purity should be mandatory, he would also be saying that totality should be mandatory. I do not think he is saying that all new languages should be Turing incomplete. Therefore, he is saying totality is optional via annotation, therefore he is saying purity is optional via annotation.

is tv_audio_wave() appending a null byte to the vector when you pass a string literal to it? Like here:

That would fuck the format up.

no, here is the char* code

Yes - being able to write something like

total pure Nat factorial(Nat n) = ...

and have the compiler then refuse to compile if it detects that factorial is impure or non-total. You would be able to use them independently, e.g.

total void negate_some_global_somewhere() = ...

pure Nat i_cant_prove_this_terminates_but_it_has_no_side_effects() = ...

or use neither of them:

Rather lost when it comes to using OpenGL with C++. Using this tutorial (http://www.opengl-tutorial.org/) to learn what I can, but I eventually want to make a snake game.

I think my biggest question is, given a window, how can I read keyboard inputs? Would I have to use cin? Because I want it to be like a regular video game, where the key press registers relatively quickly without needing to press ENTER

cin is terrible for on the fly keyboard inputs
If you want to stick to a terminal, use non-canonical mode (a text editor for example).
Since you are making a game, I would opt for SDL_input

I've been working on this build of RetroPie for ages. I basically shoved a RPi 3 into a PSX and wired the controller ports directly to the Pi's board.

I noticed soon after it was complete that the controllers were throwing random inputs when the RPi was using lots of CPU. Tracked it down to the gamecon driver, and after rewriting half of the PSX related code and adjusting timings, no more random inputs.

Fuck yeah, feels good bruhs.

So you're taking a function that turns all of its arguments into something of type b, and a 3-tuple, and the result is a 3-tuple with all of its elements of type b. Presumably the function in the first argument is able to take elements of different data types?

>>58263466
Yes - that's what the forall is for.

>>58263224
>>58263286

Yeah, that's probably it.

Write the vector to a file and open it up in a hex editor. If you see "RIFF" backwards in the hex dump it's an endian problem.

2017 is the Year of Rust; get over it!

>>58263489
No, that isn't it. Using RWFromFile and a test wave file worked, and they have everything in plaintext written like I have it in the calls. I'll look at the numbers in a hex editor to see what comes up

>>58263516
Some people are happy using crippled languages, get over it!

>>58263466
Yes, the point is that normally, even if your function was templated, its PARAMETERS (per instance) would be monomorphic. E.g. it would take a std::function<int(float)>;

But here, you can take TEMPLATED functions (and other parametric) as parameters.
So here it's like

template <typename X, typename Y>
std::tuple< X,Y,X,Y>
myFunction(template <typename a> std::function<std::pair<a,a>(a)>, std::pair<X,Y>);

If you think of one SPECIFIC instance, e.g. X = Int, Y = String

std::tuple<Int,String,Int,String>
myFunction(template <typename a> std::function<std::pair<a,a>(a)>,
std::pair<Int,String>);

our parameter is still templated/polymorphic
because of this we know we could call that parameter on BOTH of the members of our pair, e.g.
it's not just been reduced to an (int -> (int,int)) or a (string -> (string, string)), it is LITERALLY an (forall a. (a -> (a, a)))

You can sort of do this in C++, but it's not actually type safe.

>>58263406
http://www.glfw.org/

Hey guys,

I spend a lot of time practicing practice algorithms problems for job searching, but oftentimes I legitimately don't understand the solutions and can't really see how to come up with it myself.

What do you do in those situations in order to "learn" the problem even when you really dont understand it?

Or rather, what do you do to understand solutions that are really unintuitive to you?

>>58263555
By not actually type safe, I mean it will follow the regular C++ convention

>instantiate template
>does it have this operator for int? yes?
>does it have it for string? no? fail

a sort of dynamic static typing (in the sense that errors are being deferred)
and you get these errors that occur when the template is instantiated, but don't occur inside the actual function that makes wrong assumptions

while in Haskell, there is no reason to assume that any arbitrary type can be called with an int and with a string.
so something like

template <typename T>
auto func(T f) { return f(3); }

is valid C++, but not valid Haskell

>>58263555
>C++
>not actually type safe
Quelle surprise.

>>58263555

Ah, so where higher kinded types take a type constructor (templated type) and produce another type, a higher ranked type takes a function constructor (templated function) as an argument, producing another function?

Can you show me how to do monad transformers in C#?

>>58263224
Surely this should be giving you some compiler warnings? You're passing in things like uint32_t for "data". What do you think strlen(uint32_t) is going to give you?

>>58263489
Turns out I never supplied it any bit depth info

>>58263629
Those are defined as separate functions. I would have used templates, but the documentation I was reading said something about different endians for different types of data

>>58263580
An useful way to learn how to solve problems is to thing of the basic building blocks of the problem, it's properties and how they relate.

I'm supposing you don't have a STEM background right? It's something you can learn by writing proofs.

Books that may help you are:
Calc I - Tom Apostol
A transition to advanced mathematics - Smith, Eggen(requires calculus)
Any introductory book in algebra(not linear algebra)
Some book about linear algebra
Some book about mathematical logic

>>58263612
Something like that

A higher ranked type can take polymorphic types as arguments.

So the main difference is that we can re-use that same function with different types, because we KNOW it has a polymorphic type.

Another thing Haskell allows is PolymorphicComponents, which means that you can store polymorphic types.

>>58263637
Ah, ok. Headers can be annoying to get right sometimes.

>>58263686
>implying that was the only problem
it still doesn't work, same error. It has to be some endian junk or something

>tfw Im a cs major

I dont have problems "coding," or thinking about some problems, but a lot of algorithms problems that someone should prepare for job interviews can give me trouble.

I think I just need to spend more time at it and try to work through something more carefully when I dont get it.

Thanks for the recommendations. I havent done / taken calc in awhile and its something id like to do again.

>>58263682

I see. I don't tend to find a use for that level of polymorphism, but I will try to remember it in the future.

>>58263711
Alright. Just use this

http://soundfile.sapp.org/doc/WaveFormat/

and a hex editor, you'll be fine

>>58263757
The main use for the former would be that in Haskell you can have infinite polymorphic recursion, i.e.

data Fix f = FixConstructor (f (Fix f))

Given a functor, e.g. [] (list)
and omitting the constructor name (FixConstructor)

Fix [] = [Fix []] = [[Fix []]] = [[[Fix []]]]
etc, to infinity. So you end up with the infinite type
[[[[[[[[[[[[[[[[[[[[[[[[...]]]]]]]]]]]]]]]]]]]]]]]
i.e. a list of lists of lists of lists ...

>>58263802
That problem never really comes up in C#.

>>58263068
>>58263073
I'm trying to figure out how a certain defunct online game dealt with its files and cache. Here's what I know.

For any file that needs to be used by the game but isn't in its cache folder, it requests and gets the (unencrypted?) file from the server. They're all simple files, generally a texture in gif format with a seemingly proprietary mesh file appended at the end, or just another simple proprietary file. What's important to me is that they're not encrypted until they're received by the game, because they might be a clue as to what the game does.

These files are saved in the cache folder encrypted, with a file size bigger than the original, and a seemingly random name so you can't figure out what became what at a first glance. Unfortunately I'm pretty sure it's not just the original file with a xor/not applied, so I am clueless as to how to proceed. I decided to turn my head to reverse engineering, as It might be easier to just look at a specific area of the assembly code than try to crack some encryption, right? It's actually just as confusing, since I end up having to explore lots of assembly code. They're not exactly easy to sift through.

I could use some directions. What should I look for in encryptions? Or in disassemblies? Any alternative ways to tackle this?

And really, if I wanted arrays of arrays of arrays of ... in Ruby, I might implement something like this:

  def array_wrap
    [self]
  end

  def multi_send message, n, *args
    result = self
    n.times { result = result.send message, *args }
    result
  end
end

4.multi_send :array_wrap, 5 # => [[[[[4]]]]]

It won't allow infinite depth, since there's no lazy evaluation in my solution, but I probably don't need it to truly be infinite.

>real language like Java

>>58264121
No, the magic is that it is lists all the way down.
All it is is the infinite nesting of lists.
No room for ints or actual elements.

So you end up with properties that come from the structure itself - i.e. you can have an empty list, or a cons list.

Pretty sure [[...]] is sort of like a tree without values.

Similarly if you take the optional type, then you nest it, then you end up with

Maybe (Maybe (Maybe (Maybe (Maybe ...

which can be
Nothing
or Just (Nothing
or Just (Just Nothing

but if you think of Nothing as Z
and Just as S

Z
S Z
S (S Z)
this is an encoding of the natural numbers

>>58264172
The most difficult part of making a good video game is game design which does not require programming skills, albeit logical structured thinking.
There are millions of programmers who can implement a good idea, but it's hard to come up with something original.

>>58264184
Why not just make an explicit type?

data Nat = Zero | Succ Nat

>>58264184

Yes, but if it's an infinite list of lists of lists, what would be the purpose of this value? What would you use it for?

>>58264189

Ideally, that's what business majors are for. They come up with ideas to try and pawn off on the public, while we tell them why it's impossible to implement. Then they come up with another, similar idea, we implement it, and they pay us for our time.

Programmers should not be made to be the ideas guy. That's someone else's job.

With the other encoding they become distinct types. This'll be obvious in an example I'm about to give

>>58264184

data WeirdType a = Han a (WeirdType [a]) | Solo a

this is a very strage example, but if you look, WeirdType takes two forms
1) Han a (WeirdType [a])
2) Solo a

If you imagine a is our "element type"

In the first case, we have an a, but then we actually have our WeirdType again, but with the parameter instead being [a].
So our second element in the Han constructor instead contains a WeirdType of LISTS of a.

In the second case, we only have a single item of a.

x :: WeirdType Int
x = Han 3 (Han [1..3] (Solo [[1..3], [4..6], [7..9]]))

So if you look, first we have an Int
Han 3 ...
then a [Int]
Han [1..3] ...
then a [[Int]]
Solo [[1..3], [4..6], [7..9]]

So if we want to nest further, we have to store a list of our previous type.

i'm trying to develop a framework for making games (not an entire engine, necessarily) and it's driving me up a fucking wall

trying to follow data-oriented principles to make it as fast as possible, utilizing multiple threads, i.e. one to iterate through all components of the system in contiguous memory and another to pass messages from clusters of objects, etc.

unfortunately i'm just not a good enough programmer to make everything fit together. i've got some code written but its all disconnected and nonfunctional so far. i'm missing that last piece to tie every system together. if i was doing this in standard lazy OOP i would have been done with my game by now probably. wew lad

>Anyone know how to improve this?
Don't use Python.

>>58264359
What do you mean?
It's just an example.
If we instead make that a parameter

data WeirdType f a = Han a (WeirdType (f a)) | Solo a

Our old type becomes (WeirdType []) and we can create new weird types like (WeirdType Maybe) or (WeirdType ((,) Int))

Another example would be this, based on something I saw on stack overflow

data Tree f a = Leaf a | Node (Tree f (f a)) a (Tree f (f a))

This is like your regular binary tree - except that the f modifies your element type as you descend!
So for instance, Tree [] would be single elements at the top, lists on the first level, lists of lists on the second, etc etc.

not true. you don't need the concept of a null pointer to use pointers.
also, product types are not structs. they're tuples. a labelled tuple is more analogous to a struct, and these are done in a variety of ways. for example, row polymorphic types allows for labelled rows within the type for each piece of data in the struct. another solution (which Haskell uses) is having functions over something stored (more or less) as a tuple internally -- a record type T that contains f :: Float and s :: String is really syntactic sugar for a function f :: T -> Float and s :: T -> String. instead of t.f and t.s, you write f t and s T (because f and s are functions from a struct to one of its elements).
on paper, this second solution is like a fancy product type, however languages with row polymorphic record types don't have anything like C++ structs. as an example,

{x : Int, y : Int | a}

is assumed to be the type Int x Int if you think of it in terms of product types. However, the remainder of the type is polymorphic, so really all you can say is ∃T.IntxIntxT (in this case, T could be two more Int labels or even the unit type, which means there's no other info in the record).

What it comes down to it, the purpose of a programming language it to produce a computer program. You can come up with a billion levels of abstraction to hide it, but every last program is ultimately equivalent to an impure, procedural program. This program is ugly as sin, and not as easy for humans to understand, but it's the only thing a computer can understand. Because this program is ugly as sin though, many of us tend to not think about it much when designing our programs in higher level languages. And I think this is a mistake, really. We put all of our trust into a program written by other humans to magically transform our highly abstracted programs into efficient machine-understandable programs. It is not always easy to do this, and increasingly, it seems that the cost of higher abstractions may be the cost of lower performance. We seem to think that computers can get faster forever, and so many of us have no desire to make our programs faster. And when our programs inevitably are slower than our expectations, we will always find a way to blame something else. It was that goddamn JavaScript framework. It was Windows' fault. AMD CPUs are shit.

But the problem is in us. A programming language is just a tool for making programs, just as a pencil is a tool for writing letters, and we musn't forget the limitations of the paper we are writing on.

>not true. you don't need the concept of a null pointer to use pointers.
The concept of a null pointer is not necessarily a language construct but a construct of the process' environment. A process is given a virtual address space, and 0 is mapped to an invalid page, so if it is dereferenced, the process will crash with a segmentation fault. If you cannot have null pointers, then you cannot have a pointer with a value of 0. Therefore, it is not possible to store any old value in a pointer. You thus do not have raw pointers at all, but some sort of restricted pointers, like references or smart pointers.

>also, product types are not structs. they're tuples.
You have a variable that stores multiple values, each in a different memory address. Call it what you want, it's a struct.

And maybe you're working in a freestanding environment, and you need to overwrite the interrupt vector table, which in our hypothetical architecture, starts at address 0. Regular old raw pointers do this job fair enough, because pointers are just integers with a dereference operation, and different semantics for addition and subtraction.

I somewhat like Rust. It does most things pretty high level, but when you need to do something weird, you can take the safety gloves off and shoot yourself in the foot as much as you like.

/shrugs/

the values for your positions seem inaccurate. most 3d games / etc don't use algorithms to compute this, but rather 'magic numbers' which are static and pre-computed, which is maybe what you are asking.

i'm drunk and don't really use webgl so i can't really understand if vertex values are supposed to be that way, but with bigger numbers ie: 30 instead of [ -1, 0, 1 ] or 28.82094, you might have better workings.

i think the problem maybe is you have to pre-compute the ideal hedron positions beforehand and not just assume you can assign them numbers and have it work out that way.

always with this project, thanks for the anon who helped me with the strings. it works now.

so this is a simple http server (tcp sockets) with c. that send the requested html/text files to the client which is a browser in this case.

but now, the browser can request to execute a file, so when i see that the file wanted is executable or is script (bash for example), i shoulf fork a child, and that child executes the file with exec or system, but what's required in the project is that somehow the script sends his own response to the client !

what the actual fuck ? can a shell script write into a socket if i give it the file descriptor of the socket ?
or i should print the result of the execution into a file, then send that file when the child terminates ?

Well you can make a linked list that links to a doubleNode which links to an intNode etc.

The game is an old (2005) and short-lived wizgate bomberman game.

I've been trying to make a code-cross-compiler for it (what's it called when you compile between two languages?) for some days now but I can't get the hang of it.

>>58265497
What's the problem with having predicable types?
For a good system you put a type specifier in one place. Or it may even be implicitly typed in which case it's like a language with weak typing except you can get type errors at compile time.

The major complaints I hear from weak typists is that you have to write what type you have everywhere (pun and double entendre intended). But it's really not the case. It's just that a lot of languages happen to decide you have to do that. It's not required.

>>58265754

That was about to be my solution for that 'in my language'. If you can do operator overloading, you can even do it such that indexes work correctly.

If you really need to have stopping in the middle and starting at arbitrary points, you could have some sort of integer field added on top to denote which of the fields are "active"

I think it would be cool if y'all invented a computer language of emojis, and the information could be stacked,.

Language A -> Language B = Transpiler. Or just call it a compiler in general, since we can consider bytecode and machine code to be languages of some sort.

Cross compiler is where the target computer does not match the host computer (i.e. compiling for ARM Linux from x86-64 Windows)

>>58265875

You can initialize the fields, just don't use them. Use a default value.

If there seems to be too much overhead for manipulating it, wrap all of that shit in method calls.

I have an awesome terrible idea for a distributed imageboard!

Instead of doing like nntpchan and have a decentralized moderation, what if we had a large scale neural network (under the hood kind of like ethereum but with less security and checking) where this artificial intelligence would be our sole moderator, and our God.

They are very diverse. Do you have anything in mind?

>>58266232

I suppose, but even with protocols that can work out of order, it helps to have consistent packet structures. If you want a list of (int, bool, double, string), it makes little sense to mix around the order of the individual elements, or to skip one of the elements. Although mixing around the order that each of the tuples is sent may be more reasonable, so long as they can be put back together in the right order.

So, a higher ranked type is something like what the gallois theory describes?

I'm still not grasping it fully as I've only just started researching more on haskell. Could you maybe point me to some literature or maybe an example for use in one of the C-typed languages?

If no one is liable, not much, it is good to prevent shit posting. See 4chan for example, without moderation it wouldn't have the high content quality it's known for. You said you would add moderation, i just wanted to inform you.

UINT8_MAX is never not going to be 255, and 255 is much easier to type out.

Not him and I'm sure you're going to get a vague and magnanimous response but I'm thinking you could probably use this kind of thing to create segfaults and the like for the many different types and different possible types. Only a super computer would ever use them all in its typing over the existing low order values, if you catch my drift.

>>58266487

// Representation of a polymorphic function

I think it would not be that bad if it was only one site. Like just a image board. FreeNet didn't get off because being so wide makes it painfully slow.
It could use a web of trust to assign ip addresses to each post. So it would be easy to filter shit posting.

>>58266556
Yeah that's in code and essentially they're taking apples and returning chemicals but I'm wondering if maybe you understand the pragma and can find this same construct in the mathematical basis.

Your code reminds me of Legend of Zelda A Link to The Past when link looks in the mirror and get sent to the Dark World except that we don't yet have the Moon Pearl so we keep getting sent back to code.

It kind of reminds me of a lens. I figure these higher ranked types will be where we find the new main in the quantum typed languages and will act like the main manifold?

>>58266233
How would you make the neural network learn what's bad posts and what's good posts? Up votes and down votes?
I like the idea of neural networks for moderation. It's not like mods here are that much better than random selection. And mods elsewhere often have their own agendas.

I'd be more interested in a topic selector bot. The board grows in thread number based on users online and their interests. It then builds a tree dynamically based on interests and figures out by googling what's the 'hot stuff' people want to talk about. It then creates threads for those topics if there's enough interest for it and poster retention would be an indication of success.

It might just be pure shit like canv.as (iirc) but with discussion instead. But it's at least interesting.

Users would have to list their interests in some way and the neural network tries to make their interests more specific and tries to figure out their alignment (in dpt for instance it'd try to label me as an procedural programmer).

Once you've gone that far filtering off topic isn't that hard. Rules aren't that difficult to enforce because the bot knows the users sort of intimately. Though gauging reactions is still a problem. Presumably a toxic users participation would lower the amount of time people spend in the topic.

NN is so interesting but it's hard to get good training data. So generating it seems like the only good choice.
