@totallyhuman Wait, so is c guaranteed to be b * (b/a)^x for some x?

Q: Are objects in Haskell valid if there is no input?

Heeby Jeeby ManWe allow both programs and functions. Some challenges, mostly kolmogorov-complexity challenges, do not require input. This means that for some challenges you can write a function that takes no input. In many languages this is rather straight forward. For example if a challenge asked you to out...

Q: Geometric sequence generation

totallyhumanHaskell has this neat(-looking) feature where you can give it three numbers and it can infer an arithmetic sequence from them. For example, [1, 3..27] is equivalent to [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27]. That's cool and all but arithmetic sequences are fairly limiting. Addition,...

I use C++. Not too hard to write (easier than C) while still being reasonably fast (than Python) and not too verbose (Java).

@DJMcMayhem If you use & the object dies after it goes out of scope, so you can't return it, right?
Unless you do malloc, then copy the object into the malloc'd space, which sounds really annoying and not an actual solution the memory management problem.

As well as anything that can compile to JS, like TypeScript, CoffeeScript, Kotlin, etc

Stackoverflow annoys me. I can't chat on there, and i have a question that's probably not fitting for it's own question post

@moonheart08 Don't worry, SO chat is a horrible place to get help. You can ask here, it's not so bad.

I'm writing a game that's using javascript as it's embedded language (I'm familiar with JS, and i want it's versatility). I'm trying to think up an efficient way of creating new types of game objects from inside the JS. Any recommended structure for how that should be done? I'm working on a project where objects will be fairly abundant and as such will use Rust code when possible (Embedded in rust using the SpiderMonkey javascript engine)
It is, obviously, a personal project :P
And to note on what i'm using for embedding, i'm using docs.rs/josephine/0.2.0/josephine

A: Sandbox for Proposed Challenges

CrowleyTitle: Number rewinder Inspired by this SO question and little bit expanded. Your task is to rewind a given integer by one digit leftwards in a given base and return integer (move the MSD to the LSD position). You are not allowed to use strings wherever in the stack. Input: uint Number > 0, ui...

Also, another question because i've been unable to find active communities for it: Are there any active communities for Core Wars or similar activites?
Wait
Heh, PPCG counts as one, but it has no activity for it right now

@moonheart08 define efficient. And what kinds of objects
 
moonheart08
moonheart08
Efficient as in easy to use for both the programmer and the software handling it. The objects are ingame objects like items or entities

@moonheart08 what’s wrong with JS classes?

I'm stupid. Thanks for reminding me those exist.

Idk about spider monkey api but I assume it’s relatively simple compared to v8

That's why i chose it :P
Plus it actually compiles for me
so there's that

If you use typescript you can also get interfaces for more complicated OOP, IDK if you want to go that route though.

TypeScript sucks
i tried to use it once
its a horrible mix of attempted strict typed code with a loosely typed language
 
label a -- goto a
label a -- goto a
OOP in JavaScript is weird. I still don't understand it's logic... As Mego said, it's not OOP, it's OOPS :p

also the compiler is pretty stupid and needs to be told how to import everything

I liked it, but then I'm more used to strictly typed languages.
 
label a -- goto a
label a -- goto a
There are so many ways in JS to create classes...

@labela--gotoa there is really only 2 (old style and new style) but you can rearrange parts leading to the confusion
@Pavel typescript or JS?
 
label a -- goto a
label a -- goto a
You mean object generating functions & the real classes?
fine
the first looks bad, the second is weird
 
Downgoat
Downgoat
they are factories which aren’t classes but generate objects of the Object class. And then to make a new class you do a function as a constructor. Real classes are better but you can put a goat face on a sheep but it’s still a sheep
 
label a -- goto a
label a -- goto a
o.O

petition to rename object-oriented to thing-oriented
 
label a -- goto a
label a -- goto a
in JS?

Q: Core Wars and similar programming challanges in PPCG?

moonheart08Core War is a game about two or more programs written in an abstract assembly language (REDCODE) dueling/jousting/fighting. The goal of it is to get the enemy program to have no more running threads. Brainfuck Jousting is a Core Wars like game using a Brainfuck derivative instead of REDCODE. It ...
