Fuck this, I can't believe I'm even having this conversation

Alex M.

me neither

hasherr

@AlexM. I bet you learned to program because somebody told you to.

Alex M.

not really

I learned to program because I had a community expecting MODs from me

Dean Knight

Hey hash, dont get mad. He just has an opposing opinion, and its totally an okay thing for him to have

There is some merit to what he is saying

Lasse

@AlexM. how do you know he is not going to use the skills he is learning now? who the hell are you to know that?

Christian Careaga

23:00

Welcome to the internet

Dean Knight

So take that and move on if you dont care much for it

hasherr

I don't mind him having an opinion, but it bothers me when he glorifies his own opinions

Alex M.

@Lasse lol dude I just said he's going to use Git's command line for sure

I just argued about his aim

hasherr

And he backs it up with 'facts' when he's really just speculating

Dean Knight

Trust me, Alex isnt so bad. You have not seen the software industry yet :)

Christian Careaga

23:01

This is a stupid thing to have a large argument on...

Alex M.

lol of course I place my opinions higher than yours hasherr

because you know they're mine

in an argument, unless proven otherwise, you are wrong and I'm right

it's the nature of things

Lasse

@AlexM. I think your opinions suck, in general. Almost all times.

Alex M.

that's fair

it's also in the nature of things

I mean you're an arch linux user having a wallpaper that consists of 4 terminals

HOW COULD YOU NOT DISAGREE WITH ME

the windows 8 user

Lasse

lol it's not wallpaper, I use all of the terminals

Currently I got only two of them

I rebooted a while ago, which is why I have so few

Alex M.

I know, I called it a wallpaper to emphasize the fact that they cover up your screen

Lasse

23:04

But I can see the wallpaper thru them

Are you calling unity editor to be your wallpaper too?

Alex M.

it was a metaphor damnit

Lasse

A bad one, it seems.

Alex M.

not exactly

it's just a very basic metaphor

... provided you actually read some !technical literature

Christian Careaga

Why is everyone so argumentative today

Lasse

Because having an argument is fun, and good way to procastinate

Alex M.

23:06

it's worse when I'm getting ready to call it a day and go to sleep

because I'm technically not procrastinating

I regularly argue with Lasse and hash

mainly because they lack tact, just like I do

Christian Careaga

You are procrastinating on calling it a day

Alex M.

I'm looking at Dean's messages towards me and how !argumentative they are

hasherr

I prefer debates.

Christian Careaga

I'm procrastinating on my homework by reading these pointless arguments

Alex M.

I just can't even argue with him, the best I can do is "your opinion does make sense"

@hasherr you can't do a proper debate, you like to argue with me

Lasse

23:09

@hasherr This whole argument thing has been on the internet ever since the first mail list flame wars

Christian Careaga

That's why I said earlier, Welcome to the Internet

Alex M.

debates are held by people who know how worthless arguments like this one are, and never participate in them

so, sorry @hasherr, you just think you prefer debates because it makes you look hrdcr

Lasse

@ChristianCareaga I completly missed that, while being busy arguing, I saw it now :D

Christian Careaga

Haha arguing, distracts people, I understand haha

@hasherr how many people have downloaded the game?

hasherr

9 total downloads

Lasse

23:13

post it on reddit

I bet you'll get over 9000 downloads then

Christian Careaga

Yeah, share it around!

hasherr

Where should I post it on Reddit?

Christian Careaga

EVERYWHERE

hasherr

I don't know if people will like me advertising a flappy bird clone :(

Lasse

Start up a new subreddit with a topic "post your first games here"

Christian Careaga

23:16

Be proud, who cares what people think!

Alex M.

@ChristianCareaga ... someone who wants people to play his game? :P

time's up, I'm outta here

Lasse

@AlexM. You don't seem to know anything about marketing

Only thing you need is publicity

Alex M.

k bro

at least I know what the addition operator is called LOL

Christian Careaga

Some people will like it some people wont, that's the way the world works

you can't know until you try

Lasse

Think rebecca black's friday for example. It was a really crappy tune and still it got millions of views

Alex M.

23:18

marketing is out of my area of expertise

Lasse

Just because it got public

Alex M.

can't say the same about you and operators tho

cya

Lasse

@AlexM. Every time you use that, the smaller man you become in my eyes.

I don't think I'm ever able to think highly about you

hasherr

lol

Lasse

And I bet I'm not the only one, not just because of that stupid thing

hasherr

23:21

Lasse's finnish is coming out

Lasse

@hasherr It's there always, it doesn't have to come out :P

Christian Careaga

Close-minded he is.

hasherr

23:36

@Lasse My father works with Finnish people for his job sometimes. He likes them because they're so direct.

You guys don't bullshit around with your feelings.

Lasse

That has it's pros and cons

hasherr

Every culture has pros and cons.

How are finnish girls?

Lasse

I don't know how to describe. They are finnish?

hasherr

Sounds good enough to me

I went to a job interview yesterday. I actually enjoyed it.

Lasse

What's there not to enjoy?

hasherr

23:41

Well, you know kids my age. They dread everything.

I had a good time talking with the owner and stuff, though.

He seemed really interested with what I had to say, which is good.

Matt D

finnish girls are usually pretty awesome.

Lasse

They always are interested in interview situations

hasherr

Lol, this was my first interview. Maybe I'm just overly excited :P

So I found a subreddit called /r/PlayMyGame, but something about it tells me that they don't like flappy bird clones

So I'm not going to post it

Lasse

So far I have found that libgdx source is the best documentation

And damn it's weird

public Vector2 div (float vx, float vy) {
	return this.scl(1 / vx, 1 / vy);
}

What is the point in this? Why just don't do x = x / vx

Also, java passes the value, not the reference because float is a value type

I can imagine how that slows stuff down

If used a lot

Well, not that much

Not more than passing object

But still, wtf?

Why first do a division and then a multiplication, when you get the exact same result by just dividing

Matt D

its possible this.scl is able to take advantage of SSE / intrinsics

but mostly. thats pretty wtf

probably seemed like a good idea at the time

M Davies

23:54

@Lasse What are you on about? ;o

Lasse

I'm making my TD game

And I just sumbled upon that while searching for how stuff is done in libgdx

M Davies

@Lasse In C++ a multiplication is like 88% faster than a division.

Lasse

Yes, but in this case you do the division anyway

M Davies

Yes, but I would assume that is there if you and to divide multiple variables by the same division.

In that case a division and then multiplication is an acceptable thing.

Matt D

c++ doesnt really have much to do with it ;)

M Davies

23:57

What doesn't have much to do with what?

Lasse

public Vector2 scl (float x, float y) {
	this.x *= x;
	this.y *= y;
	return this;
}

It just does not make sense in this case

Matt D

multiplication / division

M Davies

Ah!

hasherr

Alright, thanks to Dean I've now got a semi-solid grip on Git

M Davies

Yeah, that doesn't make sense, @Lasse

Lasse

23:57

That's effectively x = x * 1 / vx;

M Davies

What do you mean? @MattD

Libgdx seems like a horrible thing. ;o

Matt D

if you ask any language to do A = B / C , they will most likely emit the same instructions. the performance of POD such as maths, is limited by the CPU's implementation of arithmetic rather than something language based.

POD operations, even

M Davies

Hmm? I thought it was based on the compiler optimisations.
