I need to answer more.

Downgoat

@ASCII-only ok I did a thing which is even better reason to use babel for vsl :D

ATaco

I spend too much time just Lurking on TNB.

Conor O'Brien

@Downgoat ಠ_ಠ why use babel when new node js basically makes it useless :P

Pavel

TNB is a pretty cool place.

ELI5 Babel/Node?

ATaco

I used to use nothing but PHP.

Now I use nothing but Node

Downgoat

12:37 AM

O__o GitHub calls wiki updates "Gollum Events"

@ConorO'Brien ಠ_ಠ because you are not evil programmer

mınxomaτ

I have largely converted from PHP to Hack

Pavel

Hack?

Oh, GTG.

Conor O'Brien

@Downgoat right, so I choose to use JS as an interpreted language, not as some sort of semi-compiled abomination >_>

mınxomaτ

Hack is basically PHP, but stronger. It's JIT compiled and has a sane type system.

And made by Facebook btw.

Downgoat

@ConorO'Brien maybe we should throw away computer because CPU just compiles instructions to specific electrical patterns, ewww

:P

Conor O'Brien

12:40 AM

right but JS is an interpreted language, it's very appeal is this fact. having to wait for compilation time is a bit absurd

mınxomaτ

JS now is merely a concept, not really a consistent language anymore.

Downgoat

@ConorO'Brien every JS development environment uses building in some form or another, however if you are waiting around for the things to build everytime, you are doing it wrong >_>

ATaco

I should change to luvit

Conor O'Brien

I remember waiting for like a minute or two for cheddar to compile >_>

ATaco

Because why would I want to write a webpage in JS when I can write one in Lua?

Downgoat

12:42 AM

@ConorO'Brien :/ cheddar is pre-compiled on npm

Conor O'Brien

right but for development

Downgoat

oh, then watch

mınxomaτ

@ConorO'Brien Have you tried to throw more JS at it? Maybe transpile to another language, too :P ?

Downgoat

Also basically 1% of population uses Node v7

and that doesn't even fully support classes

so pls for sake of JS community pls don't make code that only works in node v7

Conor O'Brien

@mınxomaτ yeah our stack involves transpiling JS to BF and back again

quartata

12:44 AM

@Pavel Babel is a transpiler that was made in response to the fact that browsers were taking far too long to implement ES6

mınxomaτ

@ConorO'Brien Oh that's so yesterday. We use a VM written in Rust, targeting WASM to run a LUA program emulating ECMAScript 4.5

quartata

The idea was that it would transpile ES6 to regular ES5 code at the cost of extra runtime gook and an extra compile step

Conor O'Brien

@Downgoat for the sake of those who really don't want babel on their computer because if its inherent uselessness don't make code that only works in babel

2

quartata

Node is a wrapper around V8 (Chrome's JavaScript engine) that adds I/O and a simple HTTP server to it for use for server-side applications

Downgoat

@Pavel babel basically take either 1) ES6 (new javascript) or 2) extended JS with fancy features and spits out JS

it can be ES5 JS, or ES8 JS or whatever

quartata

12:46 AM

Well, it needs a plugin for it

Downgoat

@ConorO'Brien ... you don't need babel for it

quartata

And a lot of the new things in ES2017 aren't things Babel can do

Transpiling only gets you so far when the base language is missing low-level things

like atomics

Downgoat

It's like Microsoft saying they will stop using C++ for windows so users don't need to install GCC to install windows

(MS uses C++ right?)

quartata

@Downgoat That doesn't make any sense, C++ compiles to native code

ATaco

Yeah, for the most part.

Downgoat

12:47 AM

@quartata you'd be surprised

quartata

Users don't need to install GCC

Downgoat

@quartata exactly

ATaco

Except where they don't.

I wish the GCC versioning was consistent and easy to use.

Geobits

More like .NET ;)

Conor O'Brien

@mınxomaτ whoa... incredible! lol

Nathan Merrill

12:47 AM

you know what we need? A CPU that runs C directly

ATaco

There's a CPU that runs Java natively.

Java processor

A Java processor is the implementation of the Java virtual machine (JVM) in hardware. In other words, the Java bytecode that makes up the instruction set of the abstract machine becomes the instruction set of a concrete machine. These are today the most popular form of a high-level language computer architecture. == Implementations == There are many Java processors available, including: picoJava was the first attempt by Sun Microsystems to build a Java processor aJ102 and aJ200 from aJile Systems, Inc.. Available on boards from Systronix Cjip from Imsys Technologies. Available on boards and with...

Geobits

@ATaco My brain does that sometimes

Downgoat

@ConorO'Brien btw in: because if its inherent uselessness don't. is don't supposed to be doesn't`? >_<

Nathan Merrill

oh, it runs Java byte code natively

Geobits

It used to run C as well, but I did an "upgrade" and now the C is sluggish.

Conor O'Brien

12:49 AM

@Downgoat of its, sorry

Nathan Merrill

that's a bit different than running Java natively

ATaco

Java is technically it's bytecode.

Although .java refers to uncompiled code, uncompiled code is can vary by compiler.

Downgoat

@ConorO'Brien in that case that message is a giant middle finger to entire React community

@ATaco oh no

Nathan Merrill

if Java was equivalent to its bytecode, then I could convert any program that runs on the JVM into Java trivially

Conor O'Brien

@Downgoat I mean idk what react is, but honestly, I code just fine in an environment with minimal es6 support. the rest is just bells and whistles as far as I am concerned

Downgoat

12:52 AM

¯\_(ツ)_/¯ you do you, but I'm keeping my babel forever

Geobits

Didn't Babel get struck down, fairly harshly? I remember some story about this...

ATaco

public class JavaProcessor extends CentralProcessingUnit{
	public compile(byte[] code){
		long t = System.currentTimeMillis() + 8000;
		while(System.currentTimeMillis() < t){};
		super(code);
	}
}

Geobits

Something about trying to reconcile languages angers deities.

Oh that's right, Babel was the cause of the whole mess of languages we have now. My bad.

trichoplax

More like having more than one language is a deity's idea of punishment...

Geobits

So the moral is "Babel = bad" either way. Got it.

ATaco

12:55 AM

The fact that Web Development requires JS, HTML, CSS for the frontend, and then (PHP or your flavour), and probably an SQL in the backend makes me sad.

Nathan Merrill

@ATaco I think using the same language for all of those things is a rather bad idea

Downgoat

@Geobits no you're thinking about npm in general

Geobits

Five or six languages isn't necessarily better than one. It's be nice to have two I think. One front, one back

Downgoat

@ATaco I agree with nathan, if JS + HTML + CSS were together the web would be an even biggest mess than it is today

ATaco

I'm not saying I'd prefer them apart.

I'm just saying the sheer need for multiple languages makes me sad.

Nathan Merrill

12:59 AM

like, think about GUI development outside of web development. The code is either messy or written in multiple languages (XML, CSS)

Downgoat

though with node all you need is JS(X) and (maybe SASS?) for full front & back end

Geobits

Android is fairly simple. Java + XML

trichoplax

Write front end in Nim (compiles to JS) and back end in Nim (compiles to C++)

Geobits

You can technically do without most of the XML, but people that do that have their own circle in hell reserved.

ATaco

I use node, but I try to write my frontend in HTML + CSS + JS

Nathan Merrill

1:02 AM

with android, though, if you want to persist data somewhere, you either write your own database (file), or you use a DB language :P

the frameworks for DBs do exist, but you're either mangling stuff with annotations, or writing queries in Java :P

Geobits

@NathanMerrill If you need that much. For simple things you can use their built-in storage. It works like a map basically.

Nathan Merrill

(I was meaning an offsite server)

but yeah, local storage works fine

Geobits

But yeah, a bit of SQL for the larger stuff. For simple games or apps you just don't need it

Oh, offsite is something else, sure

But that's the same for anything I guess

Nathan Merrill

I love the concept of having 1 language for everything, but coming up with a syntax that feels natural everywhere seems pretty impossible to me :P

Geobits

I dunno. Works pretty well in spoken/written languages. We as humans screwed up the simplicity of that idea.

Nathan Merrill

1:09 AM

yeah, that's why were making general purpose AI :P

Geobits

Oh we are? I must have missed that one. Link to the chatroom please :P

trichoplax

I'm led to believe it's going to be "imminent" for the foreseeable future

Nathan Merrill

oh, I was thinking the other day: Say my computer was sentient, and wanted to take over the physical world. It does have access to the internet, but stuff like hacking into secure systems is still as impossible as ever. How would it do so?

let's also say that contacting humans and getting them to do your bidding is also not allowed :P

Geobits

Sentient, but how smart?

Nathan Merrill

super smart. Well beyond human intelligence

Geobits

1:14 AM

What about standard social engineering then? Why hack crypto when you can hack people?

If it's smarter than people, then it should have no problem convincing them to let it out of the box, so to speak.

Nathan Merrill

hence the "getting them to do your bidding" is not allowed

Geobits

No, but getting them to let slip their passwords, etc?

trichoplax

If it has access to the internet, it might not even need to outsmart smart people, just to find someone somewhere it can outsmart

Nathan Merrill

like, is it possible to order something from amazon and program it without touching it?

Geobits

Right. It should be a massively successful phisher :P

trichoplax

1:16 AM

I guess you'd need to order something preprogrammed

You can order ASICs. Could you order a custom one? You'd still need to plug it in though...

It could just release a whitepaper with an invention people are then bound to want to build, little knowing it has a secondary purpose

Nathan Merrill

oh, that would be clever

trichoplax

Whoever anonymously released the bitcoin whitepaper in 2008 now has enough money to buy a small country, which is a start...

Geobits

What exactly counts as "taking over" the physical world here?

Are we talking one world government, or shadowy lizard people?

trichoplax

I guess somewhere between converting it to computronium and just levying reasonable global taxes

Nathan Merrill

ok, let me define this a bit more narrowly: The robot is super smart, but cannot speak human language. The goal of the robot is mass destruction of the human race.

trichoplax

1:22 AM

A no-op should do it then :P

Nathan Merrill

lol

trichoplax

Before we give you any more ideas, I'd just like to check that this is just hypothetical...?

Nathan Merrill

well, I mean, I am speaking a human language right?

trichoplax

Fair enough. In that case there's a large repository of effective ways to destroy the world/human species over on Worldbuilding

Geobits

@NathanMerrill See, that's something a smart computer would say.

Right after altering the definition and conditions.

Nathan Merrill

1:26 AM

I mean, we all know that the easiest way for a language-speaking computer is phishing

Geobits

Maybe that Nigerian prince is actually the first attempt by one, and it's using that to refine.

Riker

1:52 AM

@Geobits .. so something you would say?

@trichoplax such as that passive aggresive AI

Geobits

@Riker I have no idea what you mean. I may be a computer, but I'm not a smart one. That's why I asked this.

@NathanMerrill It might be dangerously naive to think a superintelligent, sentient computer wouldn't be able to and/or see the logic in learning human languages.

Nathan Merrill

oh, I totally agree

but since "use humans to do my bidding" is such a trivial answer, I was looking for something beyond that :P

Geobits

Trivial, obvious, likely... All the same :P

Helka Homba

the video is about the halting problem

a=i;a=i+2;i=0; returns 5

so the i=0 doesn't count for the implicit return

but the a=i does

@AdmBorkBork seems true

a=2;i=1; also prints 0

There is no such thing as implicit return; it's just picking up garbage from the stack.

AdmBorkBork

That would make sense, too

It is returning the default code for running correct

A: Function returns value without return statement

For x86 at least, the return value of this function should be in eax register. Anything that was there will be considered to be the return value by the caller. Because eax is used as return register, it is often used as "scratch" register by calee, because it does not need to be preserved. This...

> It probably happens that the register used for return value is in your case the same used to compute the last expression before returning from the function (on x86 targets, certainly eax).

So there you go

@DownChristopher Does input text mean an arbitrary string? If so, you should probably add such a test case.

Down Christopher

Yeah doing it now (I just posted :P)

@DownChristopher You don't have trailing spaces. Allowed or no? Also, for n=1, should the output just be the string on a newline forever?

Down Christopher

@AdmBorkBork 1. fixed rules, 2. yes with a leading space

Does it have to print one line at a time or can it print one whole wave at a time?

Q: Make text triangle waves

I was messing around on my 'ol TI-84 CE and made a program that produced this output (it was actually bigger but that is not the point): * * * * * * * * * * * * * * * * * ... I evolved it to take input text and make the triangle waves out of that. The final step was to also ta...

A: Sandbox for Proposed Challenges

Make me some ASCII cities! Your job is to pseudo randomly generate ASCII cities (top down view) with n building per row with x rows. Each house should have a number label starting with 000 and working up. First number is the row (assume x<9) and the other two are places in the row. i.e 000, 001,...

I thought TIO had a 60 second timeout?

It does

@DownChristopher what's even remotely reopenable about this?

see this:

I'm not sure that the validity check is objective here (making it hard to know who's won and who needs to be disqualified). How are we excluding answers that just hardcode assumptions about the problem? The normal fix to this would be to take the list of questions as input, but I'm not sure that works here because the questions don't follow a common structure. — ais523 15 hours ago
