@BernardoMeurer oh please

Bernardo Meurer

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

Slereah

Hm

Imagine a spacetime that is ~ $((0,1)\times(0,1), \eta)$, minus a corner with a rather steep slope

Bernardo Meurer

Slereah

The spacetime is causal and I think the causal diamond is closed

Bernardo Meurer

@Slereah Did you think about that using Free Software?

Slereah

4:07 PM

But otoh I think there's causal curves that don't intersect every Cauchy surface

@0celo7 what u think

2017

@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...

Bernardo Meurer

@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)

Bernardo Meurer

<- 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?

Bernardo Meurer

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

0celo7

@Slereah what's that again?

Bernardo Meurer

M A L W A R E

It's MALWARE

See that

0celo7

@Slereah I think I can prove that any distribution is a sum (possibly infinite) of distributional derivatives

Bernardo Meurer

4:17 PM

That means it's malware

vzn

are there any web docs on your syllabus/ class exercises? is it all in portuguese?

0celo7

You have to justify that, Bernardo

I'd like to see you tell Bob it's malware

vzn

whos bob?

0celo7

No one you'll ever meet

Bernardo Meurer

@0celo7 I'll tell him it's malware anytime

@vzn fenix.tecnico.ulisboa.pt/downloadFile/1970943312289270/…

This is the lab statement

2017

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?

Bernardo Meurer

@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

Bernardo Meurer

@vzn Don't take my grouchiness from me, it's all I have, it was there far before I met 0celo7

0celo7

I'm not grouchy.

Bernardo Meurer

4:31 PM

@0celo7 Yeah, 'cause you run malware

0celo7

You seem to like to misrepresent people.

vzn

Yashas Samaga

@Kaumudi.H I think I've found you in the comments. youtube.com/watch?v=ESU4KdRLzu0

Bernardo Meurer

@vzn memegenerator is proprietary malware

vzn

@BernardoMeurer lol found via google images. but google is malware too right? :P

Bernardo Meurer

4:34 PM

Yes

Spyware and malware

stallman.org/google.html

Thank you very much

vzn

my earlier favorite was vaporware

@BernardoMeurer stallman huh? one of the worlds biggest ~~curmudgeons~~ visionaries

Bernardo Meurer

@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/…

Bernardo Meurer

Yes

And I understand it

We're giving away our freedom for the sake of practicality

user5556984

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

Slereah

@0celo7 on the minkowski square would u say every $J^+$ is closed or not

Bernardo Meurer

@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

heather

@vzn, that was a bit unnecessary

Bernardo Meurer

@vzn Open source doesn't care about freedom

ACuriousMind

4:41 PM

@user5556984 If you wanna talk about physics you'll have to bring it up :)

Bernardo Meurer

In fact

heather

@user5556984, conversation swings between physics and other topics =)

Bernardo Meurer

I'm relicensing everything to GPL

heather

go ahead and start a physics discussion if you want

Bernardo Meurer

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

Bernardo Meurer

@heather Stop using malware

@vzn Heather is a mod you goof

heather

@vzn ::shrugs:: i don't know, but the point is that was kinda rude, mod or no mod =)

ACuriousMind

@vzn If that was supposed to be sarcastic it didn't come across that way very well.

vzn

@BernardoMeurer lol in her dreams :P

user5556984

So does anybody know what force causes a photon to reflect off a surface?

Bernardo Meurer

4:42 PM

She moderates our consciousness

heather

@BernardoMeurer no, kenshin's the only mod on that site now.

vzn

@heather think the n00b was r00d :P

heather

@vzn dude, did you not have your morning coffee or something?

vzn

@user5556984 magic :)

ACuriousMind

@user5556984 Why do you think there's got to be a "force"?

Bernardo Meurer

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

user5556984

So there is no force?

Bernardo Meurer

There's no system but GNU, and Linux is one of it's kernels!

vzn

@user5556984 use the force, Luke :)

ACuriousMind

@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

heather

@vzn really? it was a serious question.

user5556984

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

ACuriousMind

@user5556984 Have a look at this question and its answers

Bernardo Meurer

"ageism", really dude?

user5556984

Okay, thank you.

vzn

@heather so try to answer it if you know any physics & lets see how you do :P

Bernardo Meurer

4:47 PM

Do I have to make your brain Free Software so I can patch it somehow?

ACuriousMind

Calm down, both of you

If you're not going to be constructive, maybe don't respond to users who ask actual questions, @vzn

Slereah

I think some of the $J^+$ is gonna be neither closed nor open

vzn

← oh! see now! bad guy! :(

0celo7

@Slereah Minkowski square?

You mean the penrose diagram?

ACuriousMind

@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.

2017

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) :-)

AccidentalFourierTransform

I wanted to talk to Prahar, but he's never been here in the chat :-(

he wont get notified if I ping him

0celo7

Why do you want to talk to him?

2017

@AccidentalFourierTransform Who's that?

0celo7

@2017 someone who doesn't bother with JEE questions

hey

do we have to remember that or is there any method to find it

0celo7

4:57 PM

Oh my god stop with the JEE

2017

@0celo7 I'll pay the doctor's fee

Yashas Samaga

I calculated the value of pi

using randomness

AccidentalFourierTransform

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)

2017

4:59 PM

Prahar Mitra is an Indian name btw. There is a high chance that he cleared JEE. :-D @0celo7

sites.google.com/site/praharmitra

ACuriousMind

@AccidentalFourierTransform You could just write him an email, no?

2017

I was right!

He did clear JEE

sites.google.com/site/praharmitra

AccidentalFourierTransform

@ACuriousMind meh, it's not that important

2017

@0celo7

AccidentalFourierTransform

I just wanted to ping Prahar

Bernardo Meurer

5:00 PM

@YashasSamaga Free yourself from that proprietary malware

Yashas Samaga

:O

0celo7

@2017 what?

@2017 there are intelligent Indians who don't care about JEE

2017

@0celo7 Look at his profile.

ACuriousMind

@BernardoMeurer Your shtick is becoming a bit repetitive :P

2017

He qualified the JEE @0celo7

Slereah

5:01 PM

@0celo7 i mean (0,1)x(0,1) with the metric

Bernardo Meurer

@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 ?

2017

@0celo7 I'll pay the psychologist's fee :)

hey

@2017 have any idea about that

2017

Go and get checked up

Bernardo Meurer

5:03 PM

I should make a bot that spreads the word about FSF

ACuriousMind

@2017 Implying other users need psychological help is not nice, stop that now.

2017

@ACuriousMind Tell 0celot7 to stop first.

He started it

Bernardo Meurer

@ACuriousMind I'll defend and say he's not wrong and we all know it

ACuriousMind

@2017 He did not personally attack you, but you did, so I'm telling you to stop.

Bernardo Meurer

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

Bernardo Meurer

emacswiki.org/emacs/EmacsDoctor

2017

@ACuriousMind Okay. I have no wish to continue. I hope 0celot doesn't restart it.

ACuriousMind

@BernardoMeurer ...is it ELIZA or some variant?

Bernardo Meurer

ELIZA with some added stuff IIRC

But because it is FREE SOFTWARE you can go check for yourself :^)

@BernardoMeurer W7

Bernardo Meurer

@0celo7 Your main OS is MacOS

Which is almost as bad as W7

0celo7

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

But you're not one?

Fragile ego

2017

My father is.

0celo7

6:06 PM

Lol

2017

Well, technically a bit short of a million.

Bernardo Meurer

@2017 And even with all this money you choose to not be free by using proprietary malware

2017

@BernardoMeurer Eh?

What?

0celo7

Sad

Bernardo Meurer

Sad indeed

@2017 There's no system but GNU and Linux is one of it's kernels

2017

6:10 PM

@BernardoMeurer malware freak :)

Bernardo Meurer

Free yourself from all of this proprietary garbage

2017

@BernardoMeurer As a child I used many paid softwares for free :D (using Aptoide)

Bernardo Meurer

It's free as in FREEDOM

not as in Gratis

I don't care how much it costs

gnu.org/philosophy/free-sw.en.html

Slereah

@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

0celo7

@Slereah eating lunch, I will take a look afterwards

Slereah

6:18 PM

what is for lunch

0celo7

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

Slereah

but by that measure, wouldn't $J$ be closed?

0celo7

@Slereah Thai curries

Slereah

yeah but then

If $J^\pm$ is closed

0celo7

@Slereah yeah, I'm pretty sure

Slereah

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

0celo7

I see the issue. Will give an answer later.

2017

6:34 PM

@0celo7 My offer still stands, my love :)

0celo7

@2017 are you a man?

dmckee

::facepalm::

That is all.

Nothing to see here. Go about your business.

hey

@0celo7 I mean why you hate jee

2017

@0celo7 Not yet

:D

@hey don't expect a reasonable answer :D

hey

Oh man

0celo7

6:46 PM

@hey I don't hate JEE, I hate when this chat is invaded by JEE people

hey

why

0celo7

Because it's uninteresting, annoying, and I was here first

hey

We are discussing about studies

2017

"invaded" lol.....

hey

what's wrong about that

2017

6:48 PM

he's a funny guy :D

0celo7

@Slereah Just because $J^{\pm}$ are closed does not mean $J^+\cap J^-$ is compact. It's closed, sure.

Slereah

Ah, yes

Hm

hey

@0celo7 who made this rule . The one who will came first will rule the room

0celo7

It's natural law.

Slereah

What's the rule for compactness on a submanifold?

2017

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

0celo7

@Slereah You need your submanifold to be closed in the manifold.

2017

or go hunt a rabbit

Slereah

Ah, there's the issue then I guess

hey

vegetarian

lol

ACuriousMind

@2017 I told you to cut out the personal attacks.

0celo7

6:52 PM

Damn, I missed it!

heather

hoo boy.

Slereah

Hey it's our friend John Duffield

heather

interesting chat today

@ACuriousMind, sorry about that earlier with vzn

0celo7

@Slereah Btw, if you have an $n$-manifold, you cannot have a compact $n$-submanifold.

ACuriousMind

@heather You did nothing wrong

heather

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

0celo7

That doesn't even make sense.

JEE existing has nothing to do with the chat.

hey

It has

It is similiar to your reason

heather

@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

0celo7

6:55 PM

I need to rewrite my will.

hey

thanks @heather

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.

2017

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

heather

ideally, there'd be a balance, and minimal arguing

2017

6:57 PM

@ACuriousMind Stop being partial.

0celo7

I'm not attacking anyone.

heather

no one is being partial here.

0celo7

I'm attacking your currency.

2017

"your" implies a personal attack.

hey

And he is attacking your nature

heather

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

2017

Oh god, why am I wasting time.

0celo7

No, it means the currency of the country in which you reside.

ACuriousMind

@2017 Stop attacking other users. If you cannot talk civilly to another user then ignore them.

2017

@ACuriousMind 0celot attacked first. You are being intentionally blind to his attacks.

heather

6:58 PM

@2017 yes, please. no offense, but it will be better for everyone if you stop engaging.

ACuriousMind

@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.

heather

@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.
