This bait is way too obvious senpai

I'm having second thoughts on Clojure. I did some exercises in it, but there are some problems that really frustrate me. Most notably is the lack of a static type system. Runtime crashes because of type assertion are just stupid nowadays. Another problem I have with Clojure is that lack of proper pattern matching. Haskell really spoiled me with proper pattern matching.
So I think I'll ditch Lisp for ML. Any suggestions? F#, OCaml, Haskell? Does F# even run on the GNU operating system using Linux as its kernel? What's popular?

>>60015571
>Why not a bf2c?
Because that's what literally everyone does for their first bf interpreter implementation.

>I can not compile your soft. I am using a free (as in freedom) OS.

>>60015655
>Well thats pretty nice readme.md, tips for writing nice doc.
Thanks

>negative points for making it locked to damn OSX
It's not "locked to", it's implemented for it specifically. macOS doesn't understand ELF ootb and this being a toy project I don't feel like both writing it and testing it on Linux too. Too much work.

Non portable code is the mark of code monkeys.

i wanna go to machine precision in C.
i implemented an iterative method and i want to evaluate my residual errors.

the error should be smt like 1e-16, but i seem to get only 0.

im using only standard double datatypes.
is there something i can do?

Both F# and OCaml have crippled type systems which might as well be dynamic. Haskell is slightly better.

Not him, but I assume you mean a brainfuck to C translator? That's pretty basic shit compared to actually making a running executable like anon does (even though it is for non-free pig disgusting homosex os echs). You could basically just copy paste the wikipedia article on brainfuck.

https://en.wikipedia.org/wiki/Brainfuck#Commands

>>60015733
You'll never be truly satisfied with any type system.

>>60016079
Weird, I would've assumed the bf2c is annoying because C is complicated. It's supposed to be an input language, not an output one. I know ppl sometimes generate C, but it strikes me that there must be a better way such as hooking into the IL or something. It's clearly portable if done correctly tho I must admit.

>>60016114
Why is that?

>>60016114
True, but dynamic type systems are outdated. For example, Python recently got support for some static type assertion.

>>60016162
>I would've assumed the bf2c is annoying because C is complicated. It's supposed to be an input language, not an output one.
Actually, C isn't complicated at all. It's extremely simple, has a very small standard library and a very small set of keywords.

It was always intended to be a portable assembly.

>I know ppl sometimes generate C
Not sometimes, virtually all modern compiled languages have a step transpiling them into C code first. Haskel/GHCl has this, Forth has this, Rust has this etc. By supplying the right flags to the compiler, you can make it stop at the C step.

Hell, even some interpreted languages have support for converting it into C (which is trivial if the language supports JIT). There are JavaScript to C translators, Python to C translators etc.

C is not a complicated language, it's really simple. The fact that C programming is hard is not because the language is complicated, but because there's so much stuff that's undefined and implementation specific.

>>60016221
>Not sometimes, virtually all modern compiled languages have a step transpiling them into C code first. Haskel/GHCl has this, Forth has this, Rust has this etc. By supplying the right flags to the compiler, you can make it stop at the C step.
No anon. They can produce C, but they don't use as a standard step.

>>60016211
Wrong! Python3 still is and will remain dynamically typed. The type annotations don't interest the interpreter, they aren't assertion. they are to be read and statically reasonned about by a separate tool.

>>60016211
>dynamic type systems
That's impossible.

>>60016241
Even when using PyPy?
>>60016248
OK, languages without a static type system.

>>60016221
Actually, C isn't complicated at all.
I should define complicated, I mean that the syntax is human-oriented, so generating it is just a waste of CPU time and program complexity. Not saying it can't be done.

I'm pretty skeptical about this "everything that exists transpiles to C" claim, again, why don't they target an intermediate language?

What is the connection between a JIT and AOT compilation targeting C?

>>60016267
That's impossible as well.

>>60016236
>They can produce C, but they don't use as a standard step.
You are right (although some do IIRC, I'm pretty sure that GHC does this, but I may be mistaken).

However, creating C code is pretty trivial no matter if you compile to C as an intermediate step or reverse generate it from your instruction set.

>>60016275
>why don't they target an intermediate language?
They usually do, I was mistaken. See >>60016236 and >>60016287

>What is the connection between a JIT and AOT compilation targeting C?
See above. Once you have byte code, recreating C is fairly trivial.

Nth for C#, ASP.NET, Visual Studio, the entire .NET Framework, Bill Gates, Paul Allen and Microsoft™.

>>60016267
>Even when using PyPy?
Maybe there are PyPy modules that only accept programs that are type-correct and provide some benefits in return. PyPy is said to be written in RPython, a language derived from Python that's more restrictive so types can be infered, and this allows PyPy to bootstrap itself. Maybe there are already other variants of Python in the same vein. There's also Cython....

Stackful coroutines means that each coroutine has a stack. Python generators can't yield from within called function, they aren't stackful. Proper threads have their own stacks but are symmetric, not asymmetric.

My computer science course is taught in Java. One problem I had to do was about different types of books and how you should deal with having multiple genres of book.

The correct answer was to make a book class and then have nonfiction/fiction extend book and then have romance/mystery extend fiction and science/math extend nonfiction

Do Java tards really think this is more efficient than having a struct with an enum? you could do this in two bytes. And it would be better in every way.

Also who thought it was a good idea to include a cheep wrapper class around the types double and integer.

Not sure wrappers halve flops, but basically yeah. It's not a computer science course, it's an classist design course. Multiple dispatch is ok where it makes sense, but enums are fine most of the time. Note that your enum can't be dynamically extended though.

Hope they haven't been unfair to you?

it's not like math lecturers make exercises that are relevant to anything, often they won't try to explain the concepts presented at all. it's just you are such a mathfag that you ignore this. so it's no different from a programmingfag ignoring that the lecturer's inheritance example wasn't very relevant.

They are relevant to math in all its abstract purity. If you burden yourself with trying to tie concepts with unrelated real world stuff, you're either a kindergarten teacher or a POO priest. Hope you're neither.

>often they won't try to explain the concepts presented at all.
Explaining the concepts is the central goal of the lecture, was your math lecturer that bad? or do you mean 'explain' in the sense of 'illustrate' rather than 'define'? If so free your mind, that's an inferior way to think. Who needs concrete examples besides kindergarten students and POO cultists?

Can someone explain this c++ code to me for a Binary Search tree? I don't understand how it goes through the iteration for inserting a node. It says to loop until curr reaches 0, but what does that mean?

 
void BinarySearchTree<T>::insert(T d)  
{
    tree_node<T>* t = new tree_node<T>;
    tree_node<T>* parent;
    t->data = d;
    t->left = NULL;
    t->right = NULL;
    parent = NULL;

  if(isEmpty()) root = t;
  else
  {
    tree_node<T>* curr;
    curr = root;

    while(curr)
    {
        parent = curr;
        if(t->data > curr->data) curr = curr->right;
        else curr = curr->left;
    }

    if(t->data < parent->data)
       parent->left = t;
    else
       parent->right = t;
  }
}

I use both.
Yes the command line is more flexible, but 95% of the time you're going to want to use the same old tried and true commands. Build and run build scripts, run all tests, run the profiler, commit and push, etc. can all be done with a single click in an IDE. It's a matter of solving for the most common use case first. It's not like you can't use a command line alongside an IDE for more complex tasks.

>>60021350
That's nothing that can't be handle by a standalone tool like tup afaik. Or is there? and Travis CI is configured using a shell script basically. I guess the CI doesn't have the whole IDE installed, so it's mostly an ecosystem of compatible tools using sln as a format, one of which being the builder, no?

I'm sure there's standalone tools that handle it just fine too, and you could probably even doctor up a good old fashioned makefile to do it. But it's far less effort to just click on a bunch of buttons and add a few dependencies, and essentially have the IDE create that make file full of wizardry and maintain it for you automatically. That's basically how I view it, very cost-efficient maintenance of project-related things like profiling, testing and building.

As for your 1 and 2 questions, that depends on which IDE we're talking about. Most of them will let you use parts of the build system as standalones, and most of them have a proprietary part to them. The engine (compilers, linkers and core language tools like debuggers) tend to be free, but the rest of the car is proprietary if you get my analogy.

>>60021537
Could you please write in English?

assuming you meant
>CI is another tool to punish developers; it teaches them to only commit if the code is in a building state.
To which I answer no, it depends how you set up your CI. It's not a sin to break something, better to know it late than never, so no one punishes you if your CI is negative. CI helps with code quality but isn't meant to change how developers think. It's also perfectly compatible with the small increments commit philosophy, and what matters is that the tip of your git branches pass the test, not everything below that. You don't code any differently with CI, it just makes teams more productive, and helps with pull requests because you have a readily available indicator of whether merging will wreck your project or not. (Doesn't replace manual reviewing though, just helps.)

I dont really know c++ but a bit of C and Python, i'm walking through a tutorial written in c++.

What does this mean ?

struct Foo {
   bool boolean; // this i know
   Foo() : boolean(true) {} // this i don't
}; 

I know what it's doing since it's pretty obvious, i just don't know the syntax ?

Is it the same as Tile.boolean = true; ? but declared directly in the struct ?

Also do you have recommandation of books/videos i should read/watch to get up to speed with C++ ? I probably don't wan't to dive into a big book that'll teach me C++ but rather something that'll teach me classes syntax and data management in C++.

>>60021687
it sets boolean to true, but it's in the initializer list so it has different properties

>>60021672
No, he ment that instead of having CI you should punish your developers when they push non-building code. Which is pretty much the most indian thing i've seen written on this website. In any case, CI is more useful for things like... Let's say you're developing a web application. You add a new feature and you want to pass it off to QA and UX. With CI all you have to do is push and it'll automatically run the tests, build it, and host it so all you have to do is send the rest of the team a link. It's not so much about just having your commits be buildable as it's a convenience for the rest of your team that don't necessarily have an up to date version of your repo with all dev branches at all times.

Seems probable. User freedom is a question we can probably agree to disagree on. As for reusing part, see my post >>60021498, to me if you have a plain unix command that can compile a file and another to link, or whatever, you can just use http://gittup.org/tup and it will be as efficient as can be, and even if it's not it's a thousand times better to improve a generic tool than whichever clusterfuck like maven or something you use to "automate" building your "app".

Why are constructors not static?

>>60021874
You can read the first chapter if you're not already familiar with lambda calculus.

>>60021919
Because inside the constructor body you're no more in a static method, you can call instance members. Constructors are hybrid.

if you define a variable inside a loop for example, it will only exist inside the scope of the loop

if you try to compile the first code, the compiler will throw an error saying that "change" is undeclared

>>60021905
Yes, that's why it's often considered good style to declare all variables on top of the function body. change inside the do-while body "shadows", that's the exact term, change outside, and when you exit the do-while it doesn't exist anymore and the outer variable is accessible again. IMHO that's not the most useful feature in C to say the least.

>>60021971
Wait yeah I didn't notice the first example was invalid.

declaration is the key, and it's not the same as assignment. Declaration is when you create the variable with it's type, name, and scope with

float x;

.
Also note that

float x = 1;

is a shortcut for

float x; x = 1;

Do you know where to find the book?

search off-site /g/ archives for "functional programming thread"

It got a bit better. We're migrating away from qmlrs to qml-rust which works way better and is actively maintained. If you're looking for an UI library it's worth a look. Also, relm (http://relm.ml/relm-intro) looks interesting.

Moving your hand back and forth between the keyboard and mouse will wreck your arm with cubital tunnel syndrome.

Or you could just take regular breaks to rest your hands/arms and not suffer from RSI regardless of which editor you use.

Well, I discreetly brushed my hand against her behind as we exited the subway
And that's basically as good as knowing her.
