>>59667109

_<_ : Nat -> Nat -> Prop
Array : Type -> Nat -> Type
index : Array A n -> (i : Nat) -> (i < n) -> A

You can read this as:
< is a predicate on two non-negative integers
Array is a type family (type constructor) taking an element type and a non-negative integer length
index is a function taking an Array of As of length n, a non-negative integer i that is less than n, and returning an element of type A.

When you see (x : A) -> in a function type (there is similar syntax for pair types), it's a dependent function since the next type can DEPEND on x.

Pure FP is much more than Haskell.

Well Haskell wont because its already ded from not starting with dependent types and not enforcing a real standard. Or it will just become the new C with a million flavors.

The future looks brighter for FP though. Its only just gotten a resurgence, but already well on the way to superiority. The fact that pure FP gets rid of exceptions and the imperative mentality of debugging errors.

Tail recursion is elegant and as efficient as loops.
Bad recursion means stack overflow.

>>59667161
Thanks, very helpful. I'm slowly learning. Would haskell be fine for playing with this or should I jump to Idris?

>>59667607
Because the idea of sudoku is many small puzzles coming together to form a huge puzzle. (no repeating numbers in a row, no repeating numbers in a column, solving a number results in other puzzles having another piece). The point of recursive is breaking down a large problem into smaller problems solving them and then putting it all together again. That is soduku

>>59667615
Tail recursion is just an ugly and inelegant way of looping.

Does it make sense to use libraries in the STL for basic usage? For instance, using std::vector and std::strings because they are safer and more convenient than using array pointers.

It feels weird using those stuff when using a language for runtime efficiency.

>>59668002
Is what something I'd recommend? I'll suggest, don't have the outlook of studying math for the purpose of AI, or some specific purpose, because you might get bogged down by feelings of "why do I care about generating functions (for instance), it's not related to my interests"

The mathematics involved in most AI/ML in common use you will have in your 2nd or 3rd year. You can get very far with basic linear algebra and multivariable calculus. Don't fall for the meme of lin alg coming "after" calc, there's no explicit dependency on calc and it's great to start lin alg as early as you can if you're doing anything CS related. That's my advice. Oh also don't be a sperg, and take some "soft" classes, they will surprise you, even in how they inform your main interest (for instance, maybe linguistics)

pure dchar switchCase(dchar c)
{
    import std.ascii;
    return !c.isAlpha ? c : c.isLower ? c.toUpper : c.toLower;
}

void main(string[] args)
{
    import std.file : write, read;
    import std.algorithm.iteration : map;
    import std.functional : partial;
    import std.array : array;
    (cast(char[]) "test.txt".read).map!switchCase.array.partial!(write, "out.txt");
}

Reads a file, switch the cases of all letters, and write to an output file

It's cool things are pretty slow here right now. I came to math late, and out of pure love, rather than any like "oh I'm good at this, I'll pursue it" or "big money here". So I'd of course say it's very worthwhile as an academic pursuit. It underlies everything, it's the language of patterns. Definitely check out philosophy, yeah.

Hey guys, I'm creating a basic interpreter in c++, the idea at first is to let me calculate basic stuff such as an area, volume, etc but with a little of natural spanish language, the project involves searching for words in strings, then deciding what functions to call and then get the data from that same string or ask the user to specify it.

I just started minutes ago, this very first version just prints whatever I write, the problem is when using strings with more than a word because it prints n times (one per word), I want it to print just one time with the whole string in it. Any ideas?

#include <iostream>
#include <string.h>
#include <stdlib.h>
#include <chrono>
#include <time.h>
#include <windows.h>

using namespace std;

float calcula(void);
float genera(void);

Assuming you are coding from scratch

public Vector(
    double x,
    double y
)

This 2 dimension vector can be multiplied with other vector (by using dot product) with the following instruction

public static double CrossProduct(
    Vector vector1,
    Vector vector2
)

Example

private Double crossProductExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);
    Double crossProduct;

    // crossProduct is equal to 50    
    crossProduct = Vector.CrossProduct(vector1, vector2);

    return crossProduct;

}

The problem is creating an n-dimensional vector, maybe you need a dynamic array that stores the dimensions of your vector.

I'm losing motivation to continue. I've been learning programming for 3 months now. I have this problem every time I try to learn something new. At first I was spending like 8 hours a day learning and was excited to learn something new. Then my excitement began to gradually dwindle and for the past month I've been forcing myself to just spend 2 hours a day at it. And I'm procrastinating and skipping days now.

I know that if this continues for much longer I'm going to give up. But I don't want to give up. How can I get motivated to continue learning again?

The artists are the arrays, the arrays should contain the tags. The cosine I want to calculate is the comparison between the artists. The dataset is from last.fm. The dataset contains an id for a couple thousand artists, the artists id id corresponds to an artist name. Each artist has a varying amout of tags, these tags also have an id, that corrosponds to a genre. All this is needed to make a content based recommendation. The recommendation is based on the cosine between the artists.

Oh I forgot to mention that the artist can be tagged with the same genre mutiple times, so the spot in the artist array that corrosponds to a certan genre needs to be incemented for every time they have been tagged with that genre. E.g if an artist has been tagged 3 times with hiphop the spot in the array where hiphop lays needs to be incremented to 3. The weight is set to 55.5 right now because another person is working on calculating the weight of each tag in the artist.

One of the most interesting passages in today's order quotes from an October 2005 email by Google's Android boss Andy Rubin:

"If Sun doesn't want to work with us, we have two options: 1) Abandon our work and adopt MSFT CLR VM and C# language - or - 2) Do Java anyway and defend our decision, perhaps making enemies along the way"

There shouldn't be any problem with it being in python. Python is just a language and on top of that the libraries are built on top of C and C++ code.

It makes a fuckton of sense to code in python on top of such libraries as its easy to interpret and you can push out code far more quickly. Plus if you compile it, it runs just as fast as C code.

Is it valid/safe to call SQL stored procedures from a program if said program is going to be workplace specific? I have:

dbConn.Open();

string query = "select * from followup";
SqlCommand getInsureds = new SqlCommand(query, dbConn);

Can I have:

dbConn.Open();

string query = "Execute followup_GetItems";
SqlCommand getInsureds = new SqlCommand(query, dbConn);

I'm not going to have users provide any input to modify the query since the query itself will only change based on what I want to do with it; the user will just select a version of the query to use from a combobox.

Common lisp or scheme for quick prototyping? I heard scheme is very minimal so it could be easier to construct your programs out of basic building blocks, but this could also be a downside as you would have to rewrite complex structures out of those primitives, which could slow down the prototyping

Can anyone redpill me real hard on webassembly

I vaguely remember doing something like

emcc muh.cpp USE_SDL

to my c++ game a while ago and it actually worked pretty nice in the browser. But it wasn't webassembly, right? What was it? It's possible to write WASM=1 now apparently

JS is so overwhelming my dudes, so much stuff

>>59666968
We need to see your actual code. If you wrote code that's not working, and you can't find what's wrong with it, then your word that the untested example code you've supplied here is functionally equivalent to the original code can't be trusted. Especially given that it doesn't look like it would cause that problem, and we can't compile it to be sure because in its present state it's not valid C++.

All that said, here are some things I notice immediately. These problems all seem like they were probably introduced with the effort to write the example code, not carried over from the original code, but I'll point them out just in case, because you never know.

if (num < NUM_MAX) {

NUM_MAX isn't defined.

stuff();

stuff also isn't defined.

++num
This needs a semicolon.

num = 0

This also needs a semicolon.

std::cout << static_cast<int>(num);

It's bad practice for member functions of non-I/O classes to directly perform I/O operations. Just return num instead.

std::cout << test.do_something() << ...

You can't print the return value of do_something because do_something doesn't return anything. (See immediately preceding comment.)

... << static_cast<int>(test.get_num() << ...

Missing right paren.

... << test.do_something());

Again, do_something is not returning a value here. Also, you accidentally stuck it inside the call to static_cast<int>. Also, you should terminate your output with std::endl.

Tell that to the processors that implement run java bytecode directly in hardware.
Also, Java is a language, it doesn't run on anything. I think you're referring to the JVM, in which case there's no rule saying it has to be in C. You could write a JVM in Rust for example.

Java is not at all reliant on C.

Building a simple 2D platforming game for Android. It's mostly a side project, just for fun. If I could ever put it on the app store that would be sick.

Question: is it necessary to use unity? I'm pretty good with physics and wouldn't have a problem implementing my own kinetic motion equations. Stuff like acceleration, velocity, and friction I understand. Basically my question is: how hard is it to implement your own physics engine?

All I effectively told you was that you're wrong and I care. I never implied I was sad or angry about it. I'm not. Just disappointed in you.

>>59672443
Not particularly hard. Depends on how derailed it's supposed to be. Generally games have very specific physics. Unless you're doing some very resource intensive physics where you need it well optimised you're probably saving time by doing it yourself if unitys physics doesn't fit you perfectly.

A lot of game let their libraries rule them. They avoid doing features because they'd have to master the physics engine in the game. If you make it yourself you never have to feel such limitations.

Box2d is open source. It's a common physics engine example you can look at.

Yes, I agree that all those languages you listed are good enough, but they're still lacking.
Rust is better than C++ (I'm not mentioning the other languages because they don't compete in the same domain that Rust does, and C can coexist with Rust) in a lot of ways. It's basically a cleaner C++, and someone like me who has programmed in C++ for a long time and is really fed up with C++'s retarded design choices, Rust is really refreshing and interesting.
Rust is a better designed C++, it's what C++ should have been.

Well, perhaps I'll give it a look next time I'm fed up with C++'s design choices. I'm not, though. Especially since I've recently taken up doing all my compiled OOP in vanilla C, using ADTs instead of classes.

Things have changed around here. I respect your intentions, but masquerading as a hater as a joke doesn't work anymore now that real haters abound who aren't in on the joke.

>Fucking no one cares, deal with it or fuck off forever.
No. I'm taking the third option: sticking around because I like it here, and fighting it when it crops up. YOU can deal with it or fuck off forever, because I'm not going anywhere.

There is no "one fits all" allocator. glibc's advantage is to behave well in many real world case, that doesn't mean it is not worth reimplementing for your specific use case. I'm assuming jemalloc is more of a runtime constraint.

None in the structure itself. That's not how bugs work.

If there's a bug, it would appear in the implementations of functions handling the structure, not in the structure itself.

>>59673018
Not in the structure itself but in the implementation of it's operations, such as insertion and deletion.
I'm not saying it's hard to implement a linked list, it's not, I've written plenty in my kernel.
It's just a lot more bug prone than say using std::vector. It's also more time wasting and limiting for no good reason.
Also, I know the linux kernel does it a lot, but I question the widespread use of linked lists in the kernel. I know it's good for some situations such as queues and stuff, but I feel that it's slightly overused.

And that's just musls, not glibc's which is the dominant allocator on pretty much every GNU/Linux system, which is the majority of Linux desktops and servers.

The simple degenerate case of the linked list is indeed a lot more time wasting and limiting than std::vector for no good reason. However, it's still an important data structure, because it serves as the conceptual foundation for trees and graphs -- which can also be implemented in terms of std::vector, but doing so makes operations upon them more difficult to conceptualize, and therefore prone to more frequent and devious bugs that are more difficult to repair.

I fully agree.

Figured it out.
