4:02 PM
@BernardoMeurer oh please
 
I'm trying to free you
Either the users control the software or the software controls the users
Break away from your shackles and you too can be a saint in the church of Emacs
 
Hm
Imagine a spacetime that is ~ $((0,1)\times(0,1), \eta)$, minus a corner with a rather steep slope
 
The spacetime is causal and I think the causal diamond is closed
 
@Slereah Did you think about that using Free Software?
 
4:07 PM
But otoh I think there's causal curves that don't intersect every Cauchy surface
@0celo7 what u think
 
@BernardoMeurer That's too creepy (if you stare long enough!)
 
vzn
hey guys/ @Bernardo are you working on a EE cpu prj? think saw you asking about assembly language or opcodes something...
 
@2017 Hm? I have that on my laptop back, I have it on my wall, and I used to have a GNU mug and mousepad
@vzn Yes, I'm building a CPU in VHDL
It's a PITA
 
vzn
← worked on 8080 calculator for (sophormore?) EE circuits class ages ago, got great grade, better than anyone & teacher compliments :)
@BernardoMeurer VHDL? surprising... is that for transistor level? but with "blocks"? what are the components? (welcome to hardware/ computer engr)
 
<- Works on CPU, cannot figure out the opcode for a ROR
Eh, logic gates?
We also use this goddamn Xillinx Vivado software
 
vzn
4:14 PM
@BernardoMeurer are you working in teams?
 
Fucking proprietary malware piece of crap
Yes, I have a lab mate
 
vzn
lol
> Vivado represents a ground-up rewrite and re-thinking of the entire design flow (compared to ISE), and has been described by reviewers as "well conceived, tightly integrated, blazing fast, scalable, maintainable, and intuitive". en.wikipedia.org/wiki/Xilinx_Vivado
 
@Slereah what's that again?
 
M A L W A R E
It's MALWARE
See that
 
@Slereah I think I can prove that any distribution is a sum (possibly infinite) of distributional derivatives
 
4:17 PM
That means it's malware
 
vzn
are there any web docs on your syllabus/ class exercises? is it all in portuguese?
 
You have to justify that, Bernardo
I'd like to see you tell Bob it's malware
 
vzn
whos bob?
 
No one you'll ever meet
 
@0celo7 I'll tell him it's malware anytime
This is the lab statement
 
4:21 PM
Almost all microsoft softwares are malware...like Internet Explorer and Ms word...
and....so many more!
 
vzn
← iirc used mentor graphics VHDL grad EE class early 1990s
@BernardoMeurer (scanned doc...) how many opcodes will your CPU have?
 
@vzn Not many, it's a 4-bit opcode
but I have no clue how they work
cause it's powered by stupidity
 
vzn
@0celo7 you seem to know him well chat.stackexchange.com/search?user=134170&q=bob
@BernardoMeurer lol andy grove would be proud... you might enjoy this old classic but youd have to give up on some of your grouchiness (maybe 0celo7 is infecting you) :( amazon.com/Soul-New-Machine-Tracy-Kidder/dp/0316491977
 
@vzn Don't take my grouchiness from me, it's all I have, it was there far before I met 0celo7
 
I'm not grouchy.
 
4:31 PM
@0celo7 Yeah, 'cause you run malware
 
You seem to like to misrepresent people.
 
vzn
 
@Kaumudi.H I think I've found you in the comments. youtube.com/watch?v=ESU4KdRLzu0
 
@vzn memegenerator is proprietary malware
 
vzn
@BernardoMeurer lol found via google images. but google is malware too right? :P
 
4:34 PM
Yes
Spyware and malware
Thank you very much
 
vzn
my earlier favorite was vaporware
@BernardoMeurer stallman huh? one of the worlds biggest curmudgeons visionaries
 
@vzn He says crazy shit, then 10 years later we realise he was actually 100% right and regret not listening
 
vzn
@BernardoMeurer were you aware hes a serious linux luvr h8r? computerworld.com.au/article/195096/…
 
Yes
And I understand it
We're giving away our freedom for the sake of practicality
 
I don't see much physics going on here. This place gives me bad vibes.
 
vzn
4:40 PM
think theres some huge )( cognitive dissonance going on in the open source "community", but ofc goes back to very beginnings
 
@0celo7 on the minkowski square would u say every $J^+$ is closed or not
 
@user5556984 That's fine as long as your vibes are powered by free software
 
vzn
@user5556984 yeah but who cares about n00bs/ what they think/ their complaints etc
 
@vzn, that was a bit unnecessary
 
@vzn Open source doesn't care about freedom
 
4:41 PM
@user5556984 If you wanna talk about physics you'll have to bring it up :)
 
In fact
 
@user5556984, conversation swings between physics and other topics =)
 
I'm relicensing everything to GPL
 
go ahead and start a physics discussion if you want
 
I'm not making M A L W A R E
 
vzn
4:41 PM
@heather lol & do you wanna be a mod someday? :P
 
@heather Stop using malware
@vzn Heather is a mod you goof
 
@vzn ::shrugs:: i don't know, but the point is that was kinda rude, mod or no mod =)
 
@vzn If that was supposed to be sarcastic it didn't come across that way very well.
 
vzn
@BernardoMeurer lol in her dreams :P
 
So does anybody know what force causes a photon to reflect off a surface?
 
4:42 PM
She moderates our consciousness
 
@BernardoMeurer no, kenshin's the only mod on that site now.
 
vzn
@heather think the n00b was r00d :P
 
@vzn dude, did you not have your morning coffee or something?
 
vzn
@user5556984 magic :)
 
@user5556984 Why do you think there's got to be a "force"?
 
4:43 PM
'Cause if an old dog like you get's called off by someone less than half your age, and correctly so, you know you're screwing up
 
So there is no force?
 
There's no system but GNU, and Linux is one of it's kernels!
 
vzn
@user5556984 use the force, Luke :)
 
@user5556984 I'm trying to understand what you mean by that - in the quantum model of photons, the photon gets briefly absorbed by the surface, then the surface emits a photon in the direction of reflection
 
@vzn really? it was a serious question.
 
4:45 PM
Isn't photon emission random (isotropic)?
 
vzn
@BernardoMeurer ah, saw that ageism stuff earlier in the transcript kaumudi vs JR, ½-laughed at it. btw its significantly less than ½ but whos counting
 
@user5556984 Have a look at this question and its answers
 
"ageism", really dude?
 
Okay, thank you.
 
vzn
@heather so try to answer it if you know any physics & lets see how you do :P
 
4:47 PM
Do I have to make your brain Free Software so I can patch it somehow?
 
Calm down, both of you
If you're not going to be constructive, maybe don't respond to users who ask actual questions, @vzn
 
I think some of the $J^+$ is gonna be neither closed nor open
 
vzn
oh! see now! bad guy! :(
 
@Slereah Minkowski square?
You mean the penrose diagram?
 
@vzn Yes, bad guy indeed. heather was just trying to get you to be more welcoming to new users and you're being very unkind about it.
 
4:53 PM
@vzn I suppose you were just joking but you need to be careful while joking with new users (not everyone has a good sense of humor) :-)
 
I wanted to talk to Prahar, but he's never been here in the chat :-(
he wont get notified if I ping him
 
Why do you want to talk to him?
 
@AccidentalFourierTransform Who's that?
 
@2017 someone who doesn't bother with JEE questions
 
hey
do we have to remember that or is there any method to find it
 
4:57 PM
Oh my god stop with the JEE
 
@0celo7 I'll pay the doctor's fee
 
Please visit a doctor
 
I calculated the value of pi
using randomness
 
I just read the lecture notes by Strominger from yesterday, and they're very nice
I just wanted to tell him that, well, I liked them
(also, I spotted a typo)
 
4:59 PM
Prahar Mitra is an Indian name btw. There is a high chance that he cleared JEE. :-D @0celo7
 
@AccidentalFourierTransform You could just write him an email, no?
 
I was right!
He did clear JEE
 
@ACuriousMind meh, it's not that important
 
@0celo7
 
I just wanted to ping Prahar
 
5:00 PM
@YashasSamaga Free yourself from that proprietary malware
 
@2017 what?
@2017 there are intelligent Indians who don't care about JEE
 
@0celo7 Look at his profile.
 
@BernardoMeurer Your shtick is becoming a bit repetitive :P
 
He qualified the JEE @0celo7
 
5:01 PM
@0celo7 i mean (0,1)x(0,1) with the metric
 
@ACuriousMind There's no system but GNU and Linux is one of it's many kernels
 
hey
@0celo7 Why are you so jealous about jee ?
 
@0celo7 I'll pay the psychologist's fee :)
 
hey
@2017 have any idea about that
 
Go and get checked up
 
5:03 PM
I should make a bot that spreads the word about FSF
 
@2017 Implying other users need psychological help is not nice, stop that now.
 
@ACuriousMind Tell 0celot7 to stop first.
He started it
 
@ACuriousMind I'll defend and say he's not wrong and we all know it
 
@2017 He did not personally attack you, but you did, so I'm telling you to stop.
 
THANKFULLY THOUGH, Emacs, which is FREE SOFTWARE, comes with a built in psychologist!
 
hey
5:05 PM
@ACuriousMind why you do not tell anything to 0celot7
 
@ACuriousMind Okay. I have no wish to continue. I hope 0celot doesn't restart it.
 
@BernardoMeurer ...is it ELIZA or some variant?
 
ELIZA with some added stuff IIRC
But because it is FREE SOFTWARE you can go check for yourself :^)
 
hey
5:13 PM
Thanks @2017
 
@ACuriousMind What's your main OS?
 
5:28 PM
@BernardoMeurer W7
 
@0celo7 Your main OS is MacOS
Which is almost as bad as W7
 
5:56 PM
What?
@Slereah I'm away from my computer, what about the Minkowski square?
@2017 your Monopoly money couldn't pay for a decent doctor here
@hey that word doesn't mean what you think it does
 
@0celo7 Lemme draw something up*
 
@0celo7 I live in the country with the highest currency value in the world, for your kind information, my dear. en.wikipedia.org/wiki/Kuwaiti_dinar
And I have 5 millionaire neighbours
in my locality
 
But you're not one?
Fragile ego
 
My father is.
 
6:06 PM
Lol
 
Well, technically a bit short of a million.
 
@2017 And even with all this money you choose to not be free by using proprietary malware
 
@BernardoMeurer Eh?
What?
 
Sad
 
Sad indeed
@2017 There's no system but GNU and Linux is one of it's kernels
 
6:10 PM
@BernardoMeurer malware freak :)
 
Free yourself from all of this proprietary garbage
 
@BernardoMeurer As a child I used many paid softwares for free :D (using Aptoide)
 
It's free as in FREEDOM
not as in Gratis
I don't care how much it costs
 
@0celo7
Oops should be $J^-$
Anyway, are the $J$ sets closed in this spacetime?
It's just $((0,1) \times (0,1), \eta)$
Some causal curves do not intersect the Cauchy surface, but at first I thought that the $J^\pm$ were closed
but by global hyperbolicity that should not be so
 
@Slereah eating lunch, I will take a look afterwards
 
6:18 PM
what is for lunch
 
Why wouldn't the J sets just be intersections of the square with the usual Minkowski J sets
So it's closed by definition of the subspace topology
 
but by that measure, wouldn't $J$ be closed?
 
@Slereah Thai curries
 
yeah but then
If $J^\pm$ is closed
 
@Slereah yeah, I'm pretty sure
 
6:19 PM
The intersection is closed
Since the space is causal, that means it's globally hyperbolic
Which means every causan curve should intersect every Cauchy surface once
but it is not the case
 
I see the issue. Will give an answer later.
 
6:34 PM
@0celo7 My offer still stands, my love :)
 
@2017 are you a man?
 
::facepalm::
That is all.
Nothing to see here. Go about your business.
 
hey
@0celo7 I mean why you hate jee
 
@0celo7 Not yet
:D
@hey don't expect a reasonable answer :D
 
hey
Oh man
 
6:46 PM
@hey I don't hate JEE, I hate when this chat is invaded by JEE people
 
hey
why
 
Because it's uninteresting, annoying, and I was here first
 
hey
We are discussing about studies
 
"invaded" lol.....
 
hey
what's wrong about that
 
6:48 PM
he's a funny guy :D
 
@Slereah Just because $J^{\pm}$ are closed does not mean $J^+\cap J^-$ is compact. It's closed, sure.
 
Ah, yes
Hm
 
hey
@0celo7 who made this rule . The one who will came first will rule the room
 
It's natural law.
 
What's the rule for compactness on a submanifold?
 
6:49 PM
@hey man, i told you....don't expect a reasonable answer....do something more productive like eating chicken
or have an ice cream
 
@Slereah You need your submanifold to be closed in the manifold.
 
or go hunt a rabbit
 
Ah, there's the issue then I guess
 
hey
vegetarian
lol
 
@2017 I told you to cut out the personal attacks.
 
6:52 PM
Damn, I missed it!
 
hoo boy.
 
Hey it's our friend John Duffield
 
interesting chat today
@ACuriousMind, sorry about that earlier with vzn
 
@Slereah Btw, if you have an $n$-manifold, you cannot have a compact $n$-submanifold.
 
@heather You did nothing wrong
 
6:53 PM
@ACuriousMind i should've pulled out earlier and stopped bugging him
 
hey
@0celo7 Jee came to this world earlier , so you have right to say anything about it
 
That doesn't even make sense.
JEE existing has nothing to do with the chat.
 
hey
It has
It is similiar to your reason
 
@0celo7 the chat is about the discussion of physics though
JEE = physics problems
</argument> =P
 
hey
@0celo7 If your reason is valid then this is also valid
 
6:55 PM
I need to rewrite my will.
 
hey
thanks @heather
 
both sides have a point. JEE (or any main conversation in the chat) can overwhelm everything else that may be being discussed.
but by the same token, JEE problems are physics problems, and this is chat for physics stack exchange.
 
54 mins ago, by 0celo7
@2017 your Monopoly money couldn't pay for a decent doctor here
 
hey
@ACuriousMind why you don't tell 0celo7
 
ideally, there'd be a balance, and minimal arguing
 
6:57 PM
@ACuriousMind Stop being partial.
 
I'm not attacking anyone.
 
no one is being partial here.
 
I'm attacking your currency.
 
"your" implies a personal attack.
 
hey
And he is attacking your nature
 
6:58 PM
@2017 i'd take the attitude of being the better person and not getting into it. that's the better thing to do than complain to a mod, who, I might add, is a volunteer and does a great job of what they do
 
hey
not you
 
Oh god, why am I wasting time.
 
No, it means the currency of the country in which you reside.
 
@2017 Stop attacking other users. If you cannot talk civilly to another user then ignore them.
 
@ACuriousMind 0celot attacked first. You are being intentionally blind to his attacks.
 
6:58 PM
@2017 yes, please. no offense, but it will be better for everyone if you stop engaging.
 
@2017 No, his words are in no way on the same level of personal attacks that you have been displaying. This is not up for debate.
 
@2017 it isn't an attack. you escalated it. he was against JEE problems being in here. okay. you then made it personal.
please, everyone, stop taking this so darn seriously. it's a physics chatroom talking about interesting topics for crying out loud.
