The Nineteenth Byte

I think according to the C++11 standard, this should be supported Not really, because a non-static member function has an implicit first parameter of type (cv-qualified) YourType*, so in this case it does not match void(int). Hence the need for std::bind: Register(std::bind(&Class::Function...

Maltysen

@Downgoat prototypes are cool

Downgoat

4:13 AM

A.prototype = Object.create(B.prototype);
A.prototype.constructor = A;

like wat even

@Maltysen yes

I mean basic classes could be done in ES5 but for real OOP you're gonna need ugly AF hacks

Maltysen

@Downgoat snek on the other hand, even has multiple inheritance

which again, more than java

H Walters

What's "real OOP"?

DJMcMayhem

Java doesn't have multiple inheritance?

Downgoat

@Maltysen java has multiple inheritance

Maltysen

@Downgoat no

they purposely didn't put it in there

Geobits

4:15 AM

Well.... of interfaces it does.

Downgoat

@HWalters Having a single class in your code does not make it Object-Oriented. Same way having functions does not make your code functional

ASCII-only

@Geobits Not really inheritance though

You're not inheriting anything

Maltysen

@Geobits called implementation IIRC

Geobits

I agree it's not exactly the same, but at least it's done for a purpose, unlike JS's giant FU to it :P

H Walters

@Downgoat Okay, but what's "real OOP"?

Maltysen

4:16 AM

@Geobits lel

Downgoat

@HWalters Code that utilizes OO concepts. E.g. inheritance, implementation, etc.

ASCII-only

@Downgoat How does JS not do that

Maltysen

@Geobits yeah, java is coherent and deliberate and well-designed, but I just get annoyed that they designed it to be extremely redundant and purposely restrictive and stupid because they don't trust the developers

H Walters

So "real OOP" is dispatch subtype polymorphism?

Geobits

@Maltysen IIRC the idea was "the good parts of C++, without unnecessary complexity/pitfalls". It's quite debateable how well they managed that.

H Walters

4:19 AM

(inheritance -> subtype, implementation -> assuming polymorphism)

Downgoat

@Geobits good part of C++ includes speed which they seem to have forgotten :P

Geobits

@Downgoat Hahahahahahaha, says the JS user

DJMcMayhem

@Downgoat Of course it's slower. It has a garbage collector

Downgoat

Wat, Java garbage collector must be borked, it didn't collect itself :P

ASCII-only

@Downgoat Java is almost as fast

Geobits

4:21 AM

It was crazy slow in the early versions, and that reputation has carried on until today even. Java's not nearly as slow as it used to be.

DJMcMayhem

@Downgoat :O You're bashing JS? I thought that was our job.

Downgoat

>_> accidentally did JavaScript instead of Java

Maltysen

rofl

DJMcMayhem

> Wat, Javascript garbage collector must be borked, it didn't collect itself :P

Downgoat

@Geobits to be fair I'm porting Cheddar to C++ for a reason...

DJMcMayhem

4:22 AM

@Downgoat So you made up your mind, you're definitely doing that?

Maltysen

@Downgoat do snek and use RPython and pypy

H Walters

Java's a bit overly OO

Downgoat

@DJMcMayhem well I'm trying

Geobits

@Downgoat If you wanted to be masochistic about it, you should've chosen C.

DJMcMayhem

How's the BF interpreter going?

@ASCII-only what is?

I'm still trying to make parser engine

ASCII-only

@Downgoat That's what I'm doing though ;_;

@smart peoples: why does reaching curie point of LC tank change resonant frequency? there aren't any permanent magnets involved

ASCII-only

@Downgoat No why ;_;

Maltysen

@Downgoat you can't use someone else's?

Geobits

4:24 AM

@Downgoat I had some wonderful cheeses this weekend. Cheddar, Swiss, Havarte, and Gouda plate with crackers and wine. Yum.

Downgoat

@Maltysen yeah but learning Flex/bison seems hard

ASCII-only

@Downgoat Use Bison/YACC

DJMcMayhem

@Downgoat I already told you I'd help, but I know literally nothing about Cheddar, so I might be slow

Downgoat

@ASCII-only it's lex/yacc or flex/bison :P

@DJMcMayhem docs.cheddar.vihan.org :3

ASCII-only

@Downgoat but... even lojban has a bison grammar iirc

@Downgoat Yeah I mean use YACC or Bison

Downgoat

4:25 AM

@ASCII-only wat XD

ASCII-only

@Downgoat quartata was asking for it IIRC

Downgoat

@ASCII-only oh

H Walters

So, if you heat up milk to about 80 to 85C, careful not to scald it, and add some acid such as a tiny bit of lemon juice, then separate the whey from the fluid, press, and drain it... optionally adding salt, you can make paneer

If you count yabneh as cheese, you can make that with yogurt and cheesecloth... drain for about 24 hours

ASCII-only

@Downgoat pls wait for me I only need to spend a week trying to learn proper C++ (i.e. fixing all my out of scope/double deletion/free() etc issues)

Downgoat

@HWalters wait it's that easy to make cheddar package manager? :P

@ASCII-only k

i need to learn how to C++ too

ASCII-only

4:27 AM

@Downgoat Sorry I need to upload once I get home, 11pm your time or before if I get lucky

Downgoat

>_> oh. I'll probably be asleep by then

i should really by sleeping right now but clearly writing short code is more important than academic performance :P

Maltysen

@Downgoat we should just not include anything academic related on our college applications and just put all our PPCG posts

Downgoat

yes brillant

H Walters

@ASCII-only "Proper-C++" makes those problems rare

Make sure you golf the application while you're at it. Show them you're serious.

H Walters

You use smart pointers and containers, and RAII, rather than trying to match your deletes to all of your news

Maltysen

@Geobits "CV: ppcg.lol/users/31343/maltysen";

Geobits

Very nice, but I think you could use an URL shortener for a bonus.

Maltysen

@Geobits i used ppcg.lol

@Maltysen I think any potential employer would be scared off by code that looks like Krz7.wcmmsm/*@b+3k@b2h.a,<b2_.DdhKrR7.zU3*FKhK

I mean like a bit.ly or something so you don't need the /users...

@DJMcMayhem was that a real example?

DJMcMayhem

@HelkaHomba I appreciate the bringing of CMC's onto youtube. :D

Helka Homba

Thanks, I got your YT comment :) Though of course they won't be proper golfing or even coding since only viewers from here would understand :P

In fact it's hard to not use the verb "golf" when I mean "make something simpler/smaller"

@anyone how do i change a class member in C++ without getting a memory leak

feersum

"I started working out last month and golfed off 5 pounds already"

@ASCII-only You just do it.

ASCII-only

@feersum So I don't have to delete?

feersum

Only if there was a corresponding new.

That you wrote.

ASCII-only

So if it's implicitly created by the constructor I don't need to delete it?

feersum

No, that's not even on the heap, so you can't delete it.

seshoumara

hello

I noticed on the sort manual (linux) the -t option which I could use to specify a separator, but I can't seem to get it to work

echo "3 -1 9"|sort -t" " -n

I expected the output to be sorted, but it's the same. I thought maybe it's an output separator, but echo "3 -1 9"|tr ' ' \\n|sort -t " " -n does the same as sort -n.

Does anyone know how to use that -t option?

mınxomaτ

7:02 AM

a="3 -1 9";sort -n<<<"${a// /$'\n'}"

Without -t, but hardly useful.

seshoumara

@mınxomaτ nice substitution. I would however like an example with -t.

mınxomaτ

Usually, for non-NL blanks like tab, sort in bash requires a dollar sign (e.g. sort -n -t$\t etc.). But that doesn't seem to work for spaces.

seshoumara

interesting, but that gives an error here. Maybe I have an old version of sort.

found the error, it actually works with sort -n -t\t

wait no, it runs, but the sort does nothing, it's wrong

mınxomaτ

7:19 AM

@seshoumara You are aware that -t is the column delimiter, not the value delimiter, right?

seshoumara

not really, could you explain the diff?

mınxomaτ

It's used to select a column (k) to sort by.

seshoumara

aa, so for the -k option?

mınxomaτ

Yes.
