Hey, got a question. If we integrate both parts of an acceleration equation ( a = bcosθ) then do we get a formula that gives us the speed of the body? ie (a = bsinθ)

That doesn't seem right to me

**ie (v=bsinθ) **

alarge

@GeorgeSmyridis Integrate with respect to what? Replace theta by time and things go better (or make theta a function of time).

Here's how it would work.

It's the kind of question that keeps getting new answers over a long period. So you "susbsc...

feature-request

0celo7

You know a game is old when the recommended specs for maxing the game out includes 4GB RAM...

@KyleKanos I'm going through a list of 50 or so patches that I can apply to Morrowind that will make it less "broken" as you put it.

Kyle Kanos

I think they did patch the major glitch that lets you get to the end of the game

0celo7

01:00

lol, this includes a nudity mod

I'd have to see the quality first...

Or just not do it.

Kyle Kanos

It's pixels on a screen man

0celo7

NSFW

Kyle Kanos

Yeah, that's Morrowind

0celo7

Morrowind was successfully modded. Maybe. Time to run it and see if my PC blows up.

mfw not even 60fps in Morrowind now

all hope is lost

Apparently I get 40.

@ACuriousMind Curiously, the text is now readable because it is full HD.

Still tiny, but readable.

And alt+tab killed modded Morrowind.

obe

01:16

@0celo7 Do you have it?

0celo7

@obe No, I got an automated error message.

How the hell would I have it?

How would I order a book at 7, 2 hours after they close, and somehow immediately have it?

obe

I didn't read the chat where you said that.

0celo7

AA is turned on! No wonder I have bad fps!

obe

This chat has become really boring since everyone started talking about video games and computers.

I started playing starcraft II though.

Kyle Kanos

@0celo7 AA?

0celo7

01:18

LOL, the mod installer requires UAC to be off, but Windows requires UAC to be on for PDFs to run!

@KyleKanos anti-aliasing

Kyle Kanos

Ah

0celo7

For the life of me, the only thing I notice that setting doing is killing my fps

obe

If anyone plays starcraft II, my user id is obe [#1729].

@0celo7 Try starcraft II.

0celo7

How about no

I need to figure out Morrowind

I just broke it

Kyle Kanos

What FPS is it running at?

0celo7

01:21

40

It was like 300

Then I modded the fuck out of it

Now it's 40

I'll halve the AA, see what happens.

Kyle Kanos

Meh, 40's liveable

0celo7

@KyleKanos I am fine with 30 even.

Hell, I play most games on 30 so I can go high or ultra.

But this mod is not very well optimized, because, well, it's a mod.

I would like to get 60, and by fooling with the settings I should be able to do that.

I could letterbox to 1080p and increase fps.

The problem with letterboxing is that it only works with some games -- others just stretch the input and stuff looks funny.

50 fps

Getting there?

@KyleKanos Morrowind

Kyle Kanos

Way nicer looking than I recall

0celo7

Note the tiny fps counter in the top left.

It shows I only have minor tweaks left hopefully!

@KyleKanos Also not 4:3 anymore.

Glorious 8:5

I finally answered a question 3 days ago, though I only got 1 upvote.

Kyle Kanos

That quote is even bolded

0celo7

@obe I should downvote it

Using angle brackets for vectors...

Also wtf, the del operator is not a vector

Shame on you

obe

Dude that guy didn't know vector calculus.

0celo7

01:41

So stop misteaching him!

obe

I first learned that del was a vector.

0celo7

It's not

It's a map from shit to shit

obe

Though he wouldn't understand it.

Basically I answered it at his level.

0celo7

You worry about your AP scores

obe

Why?

0celo7

01:42

you're not going to get them

and alt+tab killed Morrowind again

obe

There will be a delay, though who cares?

0celo7

@obe you should

Your parents should

obe

uh... why?

0celo7

That was a really not-well-thought-out question

So your father knows if he has to hurt you or not

obe

They don't care.

Though I got all 5's.

I'm sure.

0celo7

01:46

I may or may not be deleting my text files in Morrowind

This is exciting!

obe

Why would they hurt me for taking an exam for a course I haven't taken yet? (Although that's irrelevant since I was more than prepared for it a year before)

And I paid for it with my own money.

0celo7

Because your father is disappointed

obe

Why would he be disappointed?

0celo7

Lol Morrowind won't even run anymore

aw fuck I really broke it this time

Stan Shunpike

@KyleKanos sorry back. So helpful > relevant is that the take away?

Kyle Kanos

01:52

@StanShunpike That's how I've always understood it

obe

@0celo7 Should I do the proofs in ch1 of shankar, I only did half of them before.

0celo7

I am literally a genius.

No German tech support necessary.

@obe yes

And, our prof has asked us to research the topic by ourselves

Anyways, are there any interesting algorithms on that?

Mathematics: Why the brain sees maths as beauty from this study.

Gaurav

09:22

@skillpatrol I believe appreciation of mathematical formulae is a direct appreciation of logic, and in turn, a direct appreciation of philosophy, since mathematics itself a neat method of expressing logic in the form of symbols which helps us conceive more complex logic than possible without it.

skill patrol

Jul 3 at 8:30, by skill patrol

If math is the poetry of logical ideas, then physics is the poetry of physically possible logical ideas.

:D

Gaurav

@skillpatrol Nah, literal minded folk like me might not get how math can be poetry, for example. How is yours, then, more universal than mine?

skill patrol

Are you asking how my math is more universal than yours?

If so, the question is ill defined, right?

0celo7

LOL

@KyleKanos I love how at 1800p the polygons are so sharp but the textures look like they were made for 1/4th the resolution!

Gaurav

@skillpatrol Therefore, I can safely claim copyright to the great work of lazy thought.

@skillpatrol I'm saying my 'definition' is more universal than yours.

skill patrol

09:38

Define: definition?

0celo7

I just realized...lol is a recursive acronym for "lol out loud"

Gaurav

@0celo7 Never give half answers. Show us the whole recursive infinite series.

gonenc

10:24

@0celo7 The best recursive acronym I know is Benoit B. Mandelbrot

you can easily guess for what B stands

ACuriousMind

10:40

@0celo7 Proud of you ;)

gonenc

Do you guys/gals know what happened to d20?

there is no user 357 any more?!

ACuriousMind

@gonenc It's obe now

gonenc

@ACuriousMind has he change his/her username again?

ACuriousMind

He apparently took 0celo7's pretending to have blocked him a bit too serious and made a new account

gonenc

@ACuriousMind that seems... funny :D @obe

Gaurav

10:45

@gonenc Thanks for your considered response in one of your previous comments addressing me. I agree that one cannot characterise the whole Muslim community worldwide on the basis of the actions of a few. But for a non-Muslim not living in a Muslim country like me, a bad image about Islam is conveyed when the proclaimed protectors of Muslim faith, the Saudi government conducts regular beheading sessions.

gonenc

@Gaurav I can totally see that and I should add if I were living in another country I'd probably think the same

ACuriousMind

...why the hell looks the SE font so different on a linux system? Is there no SE font? Has only one of the OS's installed it be default?

gonenc

but I'm an atheist, who defends muslims right now, which is kinda weird :D

@ACuriousMind how does it look like? I have linux and it looks just fine?

ACuriousMind

Moment, maybe I just have Firefox configured wrong

0celo7

@ACuriousMind wait till you see it on OSX

gonenc

10:47

@ACuriousMind take a ss if you want

ss as in screen shot not as in other things :D

0celo7

@ACuriousMind ...you're on Linux now?

ACuriousMind

@0celo7 Have to program stuff in C, and compiling/testing C code is a pain on Windows

@gonenc lol

I need to find this damn "allow websites to use their own font" setting first, I know it's somewhere

0celo7

@ACuriousMind post a screenshot of what it looks like

gonenc

@ACuriousMind I think it is by default like that

@0celo7 Give him a sec @ACuriousMind needs to close the tabs that -18 shouldn't see :D

0celo7

@gonenc in jeans now

ACuriousMind

10:51

No, I need to find out how I take a screenshot :D

gonenc

@0celo7 Welcome to the 3rd world countries

0celo7

Lol

@gonenc I have a fycked collared shirt though

Lol that should be tucked

gonenc

@0celo7 I'm in my pyjamas yet again

@ACuriousMind you press the button, which says PrintScr on it :)

@0celo7 why r you up so early anyways?

0celo7

Work

ACuriousMind

0celo7

10:54

Commute to work, rather

gonenc

We both wake up simultaneously (not to be confused w/ einstein simultaneity) I guess

0celo7

@ACuriousMind equations pls

ACuriousMind

The font usually looks different

gonenc

@ACuriousMind try chromium/chrome

Gaurav

@gonenc Sense of identity for every person, religious or aetheistic, is in most cases linked with the culture of his/her upbringing. Culture, in turn is heavily influenced by religion, and therefore it is pretty natural that the person will end up defending the religion of his upbringing in order to defend his/her sense of identity, irrespective of whether the person is religious or not.

0celo7

10:55

lol, license plate "Karlito"

gonenc

^this is my view

ACuriousMind

@gonenc Looks the same

skill patrol

Same here

ACuriousMind

Yeah, my font is...too narrow?

0celo7

Why only one star on my genius comment...

ACuriousMind

10:56

Dunno, it looks a bit different

gonenc

@ACuriousMind maybe this is the correct narrowness for your screen resolution

ACuriousMind

Hmm...but my screen resolution hasn't changed

Gaurav

@0celo7 Perhaps it was not so ingenious?

0celo7

@Gaurav wrong

gonenc

@Gaurav I don't think it is about identity or whatnot, I think I'd do the same for Christianity if I knew more about it

Gaurav

10:59

@0celo7 Perhaps, but it's an exception.

gonenc

@ACuriousMind Maybe windows pretended that it was lower cause it likes doing such stuff w/o telling you a priori

ACuriousMind

@gonenc possible...what is your resolution?

gonenc

@Gaurav in fact I'd delete my history here if I could.

then settings

type in font to the search bar

ACuriousMind

11:03

@gonenc Yep. Okay, I'm at 1680, mine is higher

gonenc

ACuriousMind

@gonenc Found the font setting already

gonenc

@ACuriousMind (Y)

sh*t that doesn't look like, what it supposed to look like

Gaurav

@gonenc But the difference is that one does not see the Pope publicly advocating beheading for exceptional deviation from Christian morality like the Saudi mullahs do. (What the Pope thinks privately is a decidedly different matter )

ACuriousMind

Everything seems to be in order, though

gonenc

11:05

@ACuriousMind Everything is always in order in a linux computer except when it is not

@Gaurav screw the so-called "muslims" who behead people, they are already so fcuked up

ACuriousMind

Sigh...I guess I'll just ignore the font

It's not less readable, after all, just...unusual

gonenc

👍

ACuriousMind

Okay, not everything is in order, that unicode is not displayed :D

gonenc

@ACuriousMind have you installed the restricted extras package, if not do it regardless of whether it'll solve the problem

Gaurav

@gonenc Is it because you've written a politically insensitive comment earlier ? Then I need to encourage you to continue doing the same when necessary without fear of offending someone.

0celo7

11:10

@ACuriousMind 1680?

gonenc

@Gaurav hä?

Gaurav

@gonenc Oh, then good to know that you're an alternate voice

gonenc

@Gaurav I'm not following?

Gaurav

@gonenc :D Perhaps you're not following the linking feature in chat.

gonenc

@Gaurav I am but hä (equivalent to wat in english :D) was intended to the insensitive comment thing. I didn't understand what you mean by that

what is because I've written an insensitive comment?

ACuriousMind

11:14

@gonenc Good hint, thanks! Installing Truetype fonts has at least solved the font issue

gonenc

@ACuriousMind for future reference, install the restricted extras package before everything, even before moving your mouse :D

well for that you have to update first but that is another issue :)

ACuriousMind

@gonenc I managed to do that on my own

Gaurav

@gonenc I meant that you need not always be politically correct whenever you are making any statement. Of course, such statements must be made only whenever necessary.

0celo7

What is 1680?!

gonenc

@0celo7 the goddamn resolution

0celo7

11:18

1080 typo?

I've never heard of 1680

gonenc

@0celo7 1680 x 1050

ACuriousMind

0celo7

Not on purpose?

You didn't get 8:5 on purpose?

ACuriousMind

No, it just...happened :D

0celo7

I imagine there's some Danu-type story behind that...

gonenc

@Gaurav the thing is I feel sorta obliged to correct some misunderstandings about muslim world. as I've said above I'd feel the same way if I knew more about Christianity

ACuriousMind

11:22

@0celo7 No love affair involved

gonenc

@0celo7 what is the danu-type story?

0celo7

Way to ruin the next chapter in the h Bar fanfic

ACuriousMind

gonenc

@0celo7 oi!

@0celo7 "Danu-type" definition for dummies please

ACuriousMind

gonenc

Gaurav

gonenc

@0celo7 the chapter is closed for good with that comment :D

I start in a month

gonenc

@Gaurav I didn't delete no comment? what are you talking about? :D

@0celo7 well germans don't :D

@Gaurav i utterly don't like it here for personal reasons

Gaurav

Oh, okay.

gonenc

@Gaurav which is why I'm fleeing in October :D

@Gaurav see eg en.wikipedia.org/wiki/Police_brutality#Turkey

which is only 20% of story for me not liking turkey

additional story, which has happened very recently: reuters.com/article/2015/06/28/…

Gaurav

@gonenc Interesting

Kyle Kanos

@Waffle'sCrazyPeanut For FVM/FDM, it's pretty straight-forward. For FEM, it's a little more tricky due to triangularization/hexagonalization of the domain

Gaurav

@gonenc Is it that you've been involved in protest ?

gonenc

11:49

@Gaurav I didn't involve in protest too much directly, because I knew that it would go so brutal

but I could smell the tear gas from my dorm, which like 1km far a way from taksim

well it is apparently 4km far away but if you take the distance as the crow flies it would probably be 2.5-3km

Gaurav

@gonenc Pity they don't have an India section in that wiki page.

gonenc

@Gaurav you english is good enough to read it in english ;)

@Gaurav in any case photos are enough to understand the situation

ACuriousMind

@gonenc He means that there should be a section about police brutality in India, not that it should be in another language

gonenc

@ACuriousMind sh*t :D sorry for misunderstanding @Gaurav

Gaurav

@gonenc They lathicharge here. Not sure I'd smell anything from far away, but at best I'd hear fervent screams of protesters being beaten with large sticks.

I'm preparing tea, i'll be right back.

Signatures are done. Democracy at work.

ACuriousMind

@0celo7 If they're bug patches, install them all

I installed all of the bug fixes

ACuriousMind

If they alter gameplay, don't install them until you've played the game and decided whether or not you want that part of the gameplay altered

Gaurav

You're not getting off that easy ;)

I need help with the graphics mods, some of them are not totally lore friendly

ACuriousMind

alright, I'm a vampire today anyway ;)

0celo7

I'll be taking the early train today

So I should be home at 7 = 1AM in fake time

@ACuriousMind Also, I need to practice German.

@0celo7 Is that because trains are cheaper than travelling by flight?

Ableitung means derivative

@KyleKanos Despite the fact that cheap rail services are what made America what it's today

@ACuriousMind That much I gathered

Detour

The covariant detour

Detour is Umweg or Umleitung, not Ableitung

ACuriousMind

@0celo7 Yes, I am able to get that on my own
