I think being physicist gets progressively difficulty with more time/findings/progress, as further understanding of the field requires understanding of all the previous research. Don't think programming requires one man to understand whole to progress further; you can still build on top of something without understanding the underlying structures.

Which reminds me, in our school, physics department gets only 30~50 students per year.

Grey

People often study physics with another major/minor right? I may have a limited view of physics but if you just have the theory why learn it without having the tools to actually use it and manipulate it(on a scientific level)

Lasse

You need all the theory almost daily

E=mc² for example, that is used in GPS calculations and in places you couldn't even imagine

Grey

If you're just a physicist what can you do?

BlueBug

That's true. There are many students who are taking the class as part of their course. So the building is not like ghost empty. My friend, who's just a physicist, do research.

Research, I mean, we have telescope, and he looks at the stars and do stuff.

Grey

I see.

Icy Defiance

06:15

I think another thing that hurts many explanations is how E=mc² is cited as this mysterious proof for so many things, when really it doesn't prove a fraction of them. this is because E=mc² is actually a simplified equation.

E²=(mc²)²+(pc)²

that's the full thing

and p is momentum

momentum in turn is defined as velocity*mass

Lasse

yeah, true

BlueBug

I mean it's not an applied physics. So it appears there isn't much practical use TBH. but these physics major dudes have brilliant minds. IMO there isn't much difference in terms of intellectual level between our physics major dudes and Harvard phyiscs major dudes.

Icy Defiance

when an object is at rest, p is 0, so you can simplify down to E=mc²

BlueBug

the only reason, I observed, the physics dudes in my school chose this school was because they could attend this school for free.

Icy Defiance

or when an object has no mass, both m and p are 0, so you can simplify down to E = 0...which honestly makes no sense to me. I guess I still don't get it. XD

Lasse

06:20

I'm just waiting for the warp drive

which they have a concept for already

the problem is, that the ship needs to be shaped like an egg, and the engine can't be attached to it

Icy Defiance

mm I don't think I've heard of that one yet

I heard of using gravity to create waves in spacetime or something like that, but god knows how much energy that would take.

Lasse

It's using warping the space to move thru it faster

like, creating a vacuum (not like "it has no air", but "it has no space" or something) in front of the egg-shaped thing and then buildup of space behind it

BlueBug

►

"you can't travel space faster than light, but space can do whatever the hack it wants"

Lasse

yeah that thing

the second best use of condoms I've seen

BlueBug

doing some science with condom ; )

Siddharth

06:24

are you free to discuss with me?

Lasse

yeah we're not talking about anything important

Siddharth

basically I have question for mobile orientation change

for unity game

answers.unity3d.com/questions/682174/…

above link represent my doubt

joapet99

@Lasse hello

Lasse

@joapet99 hi

joapet99

how its going?

Lasse

06:30

great, I got my stuff working finally

joapet99

which stuff

Lasse

this stuff: meta.gamedev.stackexchange.com/a/1592/32955

joapet99

@Lasse OMG. the project i am in is rated highest

Lasse

I know, that's nice project really

BlueBug

@joapet99 MalwareTycoon?

joapet99

06:34

yes

Icy Defiance

@Siddharth I don't think anyone here right now has done much mobile development. I know I haven't, and I don't even know where to start with your problem.

BlueBug

I had been massing with Unity for about a month and half now. I haven't done any orientation related stuff with Unity either, yet.

joapet99

@Lasse sad to see your project is the least popular

Lasse

I just put that in there, hardly anyone has seen it yet

joapet99

oh. you posted it for just an hour ago

@Lasse is it pyramids you generated

Lasse

06:41

no they're not really pyramids

they are more like stairs

joapet99

yes,

Lasse

they are flat on the other side

joapet99

I don't have enough reputation to vote it up

Lasse

they look like this from behind

joapet99

...

scary

is there just textures doing it

in the front

Lasse

06:44

no, I'm using colours for each side

joapet99

why don't you make colurs on all sides like the front

Lasse

because they are actually normals

joapet99

normals?

Lasse

directions where the polygon faces are pointing at

joapet99

just confusing

im just 14 you know

Lasse

06:49

It's just for test rendering, I'll replace it with smooth shading and texturing

joapet99

oh

I actually thought that

so when you said behind the scene it wasn't behind the pyramids, but the same view without textures and shaders

Icy Defiance

if you're interested in an actual explanation, it's really pretty fun.

about the normal thing

joapet99

I find 3D programming confusing

so complicated

Lasse

no it's just from behind the 3d staircase mesh

Icy Defiance

it's very complicated, until you understand it, and then it's very simple XD

Lasse

06:51

there is no texturing or anything anywhere yet, not even in the green picture

joapet99

views, camera, world space, meshes, objects, textures. SO COMPLICATED

Lasse

don't forget screen space and light space and view space and tangent space, and matrices

joapet99

ugh

Lasse

it's all actually quite easy once you figure it out

joapet99

therefore i wait for the time when im amazing

in 2D

and then I maybe take a little step

in 3D

Lasse

06:55

then your mind will get blown when you realize 3d math is actually done in 4d space

Icy Defiance

kind of

Lasse

yeah kind of

joapet99

4d is confusing

i have never seen a 4d object on earth

Icy Defiance

4D is only confusing until you stop trying to see 4D and only look at the equations.

4D equations just means you have 4 variables (x, y, z, w or r, g, b, a) instead of 3. that's it.

Lasse

yep

joapet99

06:56

what is w

Lasse

you don't have to see 4d object to understand it

it's the fourth component of 4 dimensional vector

like z is the third component of three dimensional vector

or y is the second component of two dimensional vector

joapet99

so whats the difference between 3d and 4d

Lasse

it has an extra dimension, just like 3d has extra dimension to 2d

joapet99

and what do that extra dimension do

Lasse

it's just math, nothing really changes

joapet99

06:58

so why have it?

Lasse

it makes the 3d calculations much easier

joapet99

oh

Lasse

it's easier to use 4 dimensional matrix instead of trying to use only 3 dimensional stuff

Icy Defiance

here's another barrier for you to break: +x does not mean right. it means +x. that's it. you define it to mean right with your code. or maybe the library you're using defines it to be right.

same goes for y, z, and w

they mean what you define them to mean

now there are conventions that most people follow, which is why +x is usually right

Lasse

opengl defines +x as right

Icy Defiance

07:01

only by default. if you write your own shader and camera math, you can make it whatever.

Lasse

that's true

Icy Defiance

that's also why no one can agree on whether +z means forward, backward, or up

I thought it meant forward when working with Blitz3D, then I used blender and thought it meant up, then started with OpenGL and now it means backward. XD

BlueBug

I tried to drink from empty bottle of mountain dew,realized that was my last sip. I did my best to make it last but now its over. I have no more mountain dew left. I can't do anything. stares into compiler soulless, fingers stop motion

Icy Defiance

now as far as w goes, convention states it should be used to declare whether a vector represents a direction or a position. if w is 0, it's a direction, and 1 is a position. this is only because when you multiply a transformation matrix by a vector, if the vector's w component is 0, it cannot be translated, only rotated. if w is 1, it can be either translated or rotated.

but I guess that's where things really do start to get complicated. XD

Lasse

just put 2 in w and everyone loses their mind

Icy Defiance

07:06

not really. that just means all translations are doubled.

Lasse

some men just want to see the world burn

bad batman reference

Icy Defiance

put 0.5 in and translations are halved. could be good for slow motion maybe. but there are better and far more readable ways of doing that, so I doubt it happens often. not that I have much experience outside of my own code.

Lasse

damn I'm getting tired again

I guess this is what you get when waking up 3am

BlueBug

that mountain dew, I purchased from over priced vending machine, gone. Vending machine drinks are so overpriced for their size. for 2 bucks, you can buy a whole liter of mountain dew.

joapet99

@IcyDefiance what would happen if w was 100

Icy Defiance

07:10

multiply all translations by 100

I don't think it affects rotations though, which is a problem if you're trying to do slow motion or super speed or whatever

so most people keep it at either 0 or 1 and do speed modifications some other way

@BlueBug lol it's great. go to a gas station and you can buy 1L for $1.98 or 2L for $1.75. in the same building.

the 1L is kept cold, but still

or well, I get those prices. dunno about you.

joapet99

@IcyDefiance instead of using w couldn't you just multiply with what you would like

Lasse

meh you got cheap soft drinks

joapet99

x * 1, y * 1, z * 1

Lasse

it's 2.5 euros for 1.5l bottle, or 2 euros for 0.5l bottle

joapet99

or even create a local variable called w

x * w, y * w, z * w

Lasse

07:15

sometimes there are special offers 2 1.5l bottles for 3 eur

Icy Defiance

yes you can

that's why w is usually just 0 or 1

BlueBug

#IcyDefiance my residence hall is located far from any store/gas station(that is currently open) and me no car :(. I will just sit here and wait for morning for near by stores to open. Then take a sip of mountain dew and restart coding.

joapet99

so why make this big deal out of it when its really just a thing to make multiplying easier

Icy Defiance

what big deal?

Lasse

there are actually some rules that if you are scaling with the matrices, you can't multiply normals with them since they will get whacked

Icy Defiance

07:17

oh right, I never tested how w affects scaling...

turns out it doesn't

Lasse

which is why you can't use matrices that has scaling to rotate normals

you're better off creating another normal matrix for that

which is irritating, since opentk does not support them

it has no mat3 struct :(

Icy Defiance

huh, that strikes me as odd, because setting w to 0 allows you to use matrices with translation on normals, because it won't affect them. so I guess you have to be careful anyway.

funfun

Lasse

I'm hesitant to touch my current code, it might break :(

I still have no idea what I did wrong

I fixed the data size issue, but that just made the thing crash all the time

and now that I implemented it with just the GL calls and no class abstraction, I still don't know what's wrong with the classes

BlueBug

07:46

I just played game of Dota, instead mountain dew. It's odd that I get to have blast of fun whenever I have load of things to do; other times in dota, I run into ugly players and bad team composition. Anyway naw, back to code.

Jon

BlueBug

not running straight to the kid, parenting level 999999

M Davies

How do you know the person recording it is the parent of the kid? ;D

Jon

might be a pervert

M Davies

Exactly.

Pedobear strikes again.

BlueBug

shivers such a dark twist.

The worst scenario I could think of was mom sleeping with other guy, so the guy(husband) not being real parent of the kids. But here now my depth of though expanded to include possibility of pedobear thanks to you all.

Now I have no other option but live the rest of my life second guessing who's pedophile.

myInsecurity++

Lasse

10:49

ffs how fucking hard it can be, I'm trying to teach a friend who failed the java test how for loop works

this is just irritating

Jon

some people got it... some people don't

I realized this in college pretty quickly.

our class of 30 went down to 7 in the 2nd year

BlueBug

That's quite case many times, some people just not getting, but try to be patient as long as your friend tries, I must say.

Jon

i read that like a really bad fortune cookie

BlueBug

lel

Lasse

I think he's trying the hardest he can, because he really wants to pass it, but he is still like "hurr durr how can a line start from zero"

Jon

10:52

Free your mind neo.. tell him that.

Lasse

then I try to show "it does not have to start from zero, here , use int x = 1;"

M Davies

How can you not get a for loop?

Lasse

"me no understand"

Jon

if he can't grasp a for loop, he is one of the non logically thinking people

BlueBug

IMO, best teacher is the patient one, and the best student is the one that doesn't give up. I did not understand recursion when I first started.

Jon

10:53

He will never be a programmer

I seriously think that some people simply can't learn to think logically enough to be competent at programming.

M Davies

Show him with two loops, one that goes from 0 to 4 and then another from 5 to 9 and tell him it will come out with 10 loops. Maybe he'll understand then?

Jon

such a long upward battle, lol

Lasse

I'll try

BlueBug

@Jon That, I think, is very controversial topic, I am trying to find article I read on codehorror, grrr I can't find.

Jon

they hired a guy with ADD at work

M Davies

10:56

I don't know how someone could be so illogical they can't understand how a loop works.

Jon

They had him coding for a while, and wanted me to coach him

everytime I tried explaining things to him, he would change the subject

He's a tester now

BlueBug

ah there it is

separating-programming-sheep-from-non-programming-goats/ blog.codinghorror.com/…

M Davies

I could sit down one of my grandparents and probably teach them how a for loop works and they don't understand anything computer related usually.

Lasse

my grandparents would just refuse to understand

Jon

Articles proves my point.

Either they don't want to learn, or they can't change their way of perception or thinking.

0 is nothing how can it be something?

How can something call itself? that makes no sense

BlueBug

11:00

yes. he's on your side but the replies have varying opinion.

Jon

Also, girls that I know how are good programmers, and pretty weird

or lesbians

BlueBug

yeah. I did notice that from my experience. Never seen straight woman who's really into programming.

Jon

Kinda wonder the thinking logically gene was passed down to men and not women

Or maybe working with nerds and computers is just not featured enough in glamour magazines

programmer in the making here:

BlueBug

awwww

ok, me heading to class naw. C ya people, have a nice day handsome souls of internet.

Martin Sojka

@Jon Strange. The only generalisation of all the girls I met who are good programmers is that they are female. Beyond that, I know nothing of anything distinguishing them from the general population, nor do I care about such trifles.

You can code, you're in. You can't, you're out. That's all there is to it.

Jon

11:10

LOL, well I'm a self-proclaimed ladies man.. so when I see a girl programming i'm on it

BlueBug

r u? really? that's... hot.

Jon

If they are not lesbians, they are not good programmers, lol.

LOL, yeah I am ;)

BlueBug

slips in piece of paper with phone number ;)

Jon

lol

Kevin van der Velden

And this is (part of) why there are so few women programmers

Jon

11:12

are you female or something?

Lasse

most likely something

Jon

hahahaha

BlueBug

lel. I am gay man who's as well into lesbian man, sorry me no female :(

Jon

Actually, I would imagine girls like the attention

lesbians can be cool , if they don't hate men

lol

Lasse

if they don't hate men they probably are bisexuals

Kevin van der Velden

11:14

@Lasse I... you seriously think that?

Lasse

lol not too seriously

a girl once told me that most of them are not straight, instead most of them are bisexuals

Jon

i slept with a bi once

she started working here as a programmer

did my thing,and a few months later we are having nooners

BlueBug

sexuality can be complicated shit. I am not into girls most of the times, but soemhow I find lesbian man to very appealing.

Lasse

yeah it can

Jon

Everyone has their own tastes

BlueBug

11:18

now really gotta go, going to be late for class. c ya all you beautiful souls of internet. v_v

Lasse

yes, I am beautiful. see you

Jon

ahh school...

still paying for that shit

try to eliminate as much student dept as possible before you graduate

or not put yourself in debt in the first place if you can

government here in canada makes billions every year in interests on student loan debt

My opinion is they should eliminate interest on student loan debt...

because they are double dipping if you think about it

also worth mentioning that a student loan debt cannot be defaulted on -- it follows you to your death

This is the only type of loan that I know of that works this way...

Lasse

11:42

here in finland students are paid to go school

but if you get paid, you can't really do additional work to get more money, and the money you get is pretty limited

Are you still there, server? It's me, Margaret.

well explained

morning guys

Kevin van der Velden

Morning

Jon

11:59

simplified, yes, that is exactly what the problem is

Alex M.

can anyone guess the operating systems here? :D

Jon

what the hell, is that all the same phone?

Alex M.

yes

it's the galaxy s5

Kevin van der Velden

@AlexM. some nokia one, windows, android?

Alex M.

it has like 3 interfaces at the same time

the menu is all touchwiz

Kevin van der Velden

12:01

Nice

Alex M.

the settings look like tizen

and whatever google has samsung was not able to reskin

Jon

so when you navigate the phone, the UI changes around like that?

Alex M.

so you jump between different GUI styles constantly

Jon

that is stupid

Alex M.

I know

> It's amazing Samsung is as successful as it is with software like this. A lot of people give it a pass because they are used to it by now, but compared to a stock Android device or iOS, the Galaxy S5 software is a mess.

arstechnica.com/gadgets/2014/04/…

Jon

12:02

one of them is the appstore though.. so not really their fault? or can you skin that?

Alex M.

nope

but they clearly had no idea what to do

Jon

i'd get the HTC one M8

instead of that

Alex M.

I'd get anything instead of samsungs tbh

I hate the shape of that home button

I think the Xperia Z is currently the most beautiful phone

sony sure makes them look classy

Jon

yeah... the new one is coming this summer

Alex M.

#Jon Arleady deep in the trap of student loan. YOLO. College doesn't come twice, u know? It must be worth all that money in the end.

Though it's under my parents name, well. I promised my father that I will pay it. Couldn't take the loan under my name due to circumstances.

Alex M.

dogs are animals that gather in packs and hunt together

cats only sit around each other

and bang whatever they can find

cats are also more silent than dogs

and don't hump your leg

and don't mess up the house with saliva

a cat can kill birds and rats and feed itself

that means less money spent for food by the owner

cats don't smell like dogs do

JESUS CHRIST THE SMELL OF DOG

Almo

cats purr. end of discussion.

Alex M.

do you even want more reasons as to why cats are superior to dogs

also

not every dog can be a doge

but every cat can be a lolcat

it just has to be a cat

Uncanny valley

The uncanny valley is a hypothesis in the field of human aesthetics which holds that when human features look and move almost, but not exactly, like natural human beings, it causes a response of among some human observers. Examples can be found in the fields of robotics, 3D computer animation, and in medical fields such as burn reconstruction, infectious diseases, neurological conditions, and plastic surgery. The "valley" refers to the dip in a graph of the comfort level of humans as subjects move toward a healthy, natural human likeness described in a function of a subject's aesthetic ...
