good night

HELLO IS MY COW DED

HOW DO I FIX IT

Sir Cumference

@enumaris Ya know, I just looked. One of your answers is on the hot network. That's pretty lucky

enumaris

yeah, that's how I got like 160 rep today lol

Sir Cumference

It took me a few weeks to get 160 rep at first...

good night

"hey enumaris how'd you get all that rep"

balls

enumaris

06:03

yeah my stack overflow is at like 79 rep even tho I've been there for a while

all the coding questions are either too hard or too specific or too tedious

XD

good night

ahem I don't like to brag but I've only been on this site for a few years and I have 21 rep

Sir Cumference

@enumaris How to get rep on Stack Overflow: answer the most basic questions about the most common programming languages

@goodnight ...

I am so angry now

enumaris

I try to find them...but they are usually answered quite nicely already

good night

angery reacts only

enumaris

I wouldn't have much to contribute lol

Semiclassical

06:05

@goodnight that's...kinda hypnotic. and creepy.

good night

@Semiclassical can you help

i already checked stackoverflow

Semiclassical

nope

I know literally nothing about that stuff

good night

rip he was my only friend

bye boiye cow

now this chat's my only resolve

Sir Cumference

To be real here I haven't gotten rep on physics in like 3 years

good night

you lost some though

Sir Cumference

06:08

I just hung around here because it's an active chat

good night

cf. my free bounty reward

Sir Cumference

@goodnight .............

@goodnight after which you promptly deleted your account...

enumaris

lol

good night

@SirCumference i'll never forget that though

enumaris

what is your background in physics @SirCumference?

good night

06:08

i was touched

Sir Cumference

@goodnight just...just stop

good night

time for this

Jan 13 '16 at 22:57, by FenderLesPaul

I had a dream that @0celo7 was touching me relatively

Secret

Sir Cumference

@enumaris Well I'm a physics major, but I'm far more interested in astronomy

Secret

I want to be an alien that can see the uncountable possibilities directly, but I am only human

Sir Cumference

06:10

Which I became a huge nerd about in high school, but haven't had many classes in college

enumaris

High five :D Astronomy is awesome

Sir Cumference

high fives

good night

@Secret same I'm also HUMAN and I love doing HUMAN things like BREATHING and EATING cereal

Sir Cumference

Discovered Astro SE, which expanded my knowledge exponentially

Now I'm just waiting for the chance for my physics knowledge to be applicable to something more interesting...

enumaris

any particular field of Astro interest you the most?

Sir Cumference

06:11

@enumaris Cosmology or stellar physics are some of my favorites. Planetary science is the only one that really bores me though.

enumaris

Almost everything in astro requires physics so, there should be a lot of applications...

good night

i love pluto

enumaris

Cosmology for example relies heavily on GR

Sir Cumference

Yeah. I've taken some basic cosmology courses and they were absolutely mind blowing.

enumaris

Stellar physics is a mix of thermodynamics, fluid mechanics, and gravitation

and radiative transport

good night

06:13

i specialize in crop formations i.e. the abstract art that aliens work so hard to produce and I think that's beautiful

Sir Cumference

Are you a grad student in astronomy?

good night

finished grad school last week finally

self taught astrology phd

Sir Cumference

@goodnight not you >_>

good night

my bad

Sir Cumference

@goodnight Welp, it's been a year. How've things been

good night

06:16

cool and good

Sir Cumference

have ya taken analysis?

good night

i learned how to count to 50

Sir Cumference

ok

that's sort of close to infinity

good night

ya if you superimpose the 5 on the 0 you'll get $\infty$

enumaris

haha I graduated like 5 months ago

Sir Cumference

06:18

@enumaris Oh, neat. Postdoc?

enumaris

I decided not to go do a post doc

Secret

I will worship anyone who can count to the uncountable, lol

enumaris

too much research....

0, 1

does that count

[0,1]

how about that

Sir Cumference

Ah, I still haven't told @goodnight my famous physics joke

Secret

worships enumaris

Now try:

$\Bbb{R}^{\Bbb{R}}$

::Maniacal laugh::

enumaris

06:20

lol

good night

:41348435 cuz he could bench 500

Secret

Meanwhile, Valve still cannot count to 3

good night

didn't know newton was into forced

enumaris

I think

HL3 is gonna be the biggest dissapointment

in the history of disappointments

good night

@SirCumference what does that even mean

and why'd you delete it

Sir Cumference

06:22

@goodnight It's a pun

enumaris

It's already been built up so high that no matter what it is, it's gonna be a disappointment

Sir Cumference

@goodnight Wow. The person who asked that question had 1000 rep.

Solely from a single question too.

good night

looks like i need to rethink my priorities in life then

Sir Cumference

Literally only one of his questions had a positive score. And it was 238.

good night

@enumaris since when do people look up to disappointments?

enumaris

06:24

hmmm

good night

source: am tall and nobody looks at me

enumaris

:(

it feels like it takes too much effort to answer most of the questions I find...

Sir Cumference

@enumaris Oh didn't see that. So you're a prof?

enumaris

I start typing...and then I realize my post has to be so long...and then I give up

No, not a prof heh, I'm unemployed at the moment D:

Looking for a job lol

Sir Cumference

@enumaris It gets fun writing detailed answers when it's interesting and you learn along the way.

enumaris

06:28

most of the time I just give up cus it's taking too long lol

good night

@enumaris I'm currently employing

full time human clock

you just gotta hold your hands out to the time

50/hr

enumaris

that's not a bad rate...

good night

includes food and bed

but the bed's vertical is that alright

@enumaris ya 50 cashews an hour is quite fair i'd say

enumaris

D:

not really a cashew fan...

Sir Cumference

Though over time I've a sad number of OPs that won't accept an answer, due to the most bizarre reasons

Ex:

This chart doesn't look real because how come it's Now when they are all same!! — Archi Feb 5 at 14:32

good night

06:32

oh we also offer laundry detergent

50ml/hr

enumaris

hmm...

Sir Cumference

Howdy @peterh

good night

it's of the blue variety

rare liquid

peterh

@SirCumference Sircum :-)

Sir Cumference

@goodnight What do you call the inverse of differentiation

good night

06:36

@SirCumference is this a trick

Sir Cumference

@goodnight No it's an opinion

enumaris

Anti-differentiation

good night

sumentiation

Sir Cumference

@enumaris thumbs up

good night

tbh that's not even fully wrong

Sir Cumference

06:37

There was a discussion earlier today on the term "indefinite integral"

good night

@SirCumference this isn't facebook it's called starring

cool

we didn't deserve this

Sir Cumference

Imma try and head to sleep

Good night @goodnight and @enumaris

enumaris

night~

good night

night

@SirCumference indefinite integrals are just integrals having a definition crisis

it's difficult yuh know for a single integral to make ends meet

has to let ppl do them all the time

Sir Cumference

Wow...I dropped my charger plug into a jar of mayonaise

Now it's not working...

good night

06:43

i don't want to know what you were doing with that mayonnaise.

Sir Cumference

Oh very funny... >_>

good night

you set yourself up for that one.

enumaris

lawl

good night

don't go to sleep @SirCumference

who ends a party after midnight?

consider all the things you could be doing with that jar of mayonnaise while simultaneously talking to us.

Sir Cumference

07:13

@goodnight what on earth is wrong with you...?

that's just a creepy joke

"for linux" option

John Rennie

Hmm, you must have a different version of Windows.

If you open Explorer and go to File/Help/About Windows what does it show?

I get:

Anonymous

1703

John Rennie

That's fine. My version is 1709 because that's the Fall Creators update, which will be appearing in your Windows update any day now.

But 1703 should have the Linux subsystem.

Anonymous

08:02

Yeah, I dunno why it doesn't have it listed

John Rennie

If you go back to Control Panel and click System what do you get?

That's mine

John Rennie

Ahhhhh

You've installed 32 bit Windows 10

That was an odd thing to do, given that you have a 64 bit CPU ...

Anonymous

My previous Windows (Windows 7) was also 32-bit, so I thought it won't support 64-bit one. But later I realized it is x64-based processor :P

Anonymous

Actually the guys at the repair store had changed it from 64-bit Windows 8--> 32-bit Windows 7

Anonymous

08:06

Now that I look back....:P

John Rennie

The 32 bit version of Windows is missing some features of the 64 bit version, and it appears that the Linux subsystem is one of them. I'm afraid there's nothing you can do unless you wipe the disk and reinstall.

Anonymous

@JohnRennie Okay, I'll try to reinstall Windows 10 this week if possible. I need to follow the steps you had once told me a few months back, right? Lemme find the transcript

John Rennie

@Blue It depends how badly you want the unix subsystem.

Anonymous

@JohnRennie It's not urgent or anything. I want to get introduced to Linux . Have been hearing about it's advantages from quite a few people for quite sometime.

Anonymous

So, I'm going to reinstall Windows this week someday, and ping you when done! :)

John Rennie

08:10

Linux doesn't have any advantages over Windows 10 other than being free

It's no better and no worse - just different.

But universities tend to use Linux a lot, mainly because it's free and their budgets are limited.

user8663905

Yeah, I'm learning C and our college uses Linux too.

Anonymous

I see, hmm. Actually I needed to install Windows 64 bit anyway. 32-bit version doesn't support many of the softwares I need like Matlab.

Bernardo Meurer

@JohnRennie That's not true

user8663905

So, I have a quick question for anyone familiar with thermodynamics and partial differential equations: Why is it said that the Fourier heat equation assume an infinite speed of propagation?

Bernardo Meurer

It's not about being free, it's about being Free

As in Freedom ;)

Also, POSIX compliance matters for people

And don't come at me with "Windows has a POSIX subsystem", that's not what I'm talking about

I mean actually being an entirely POSIX-compliant OS

I speed tested my old Precision, that uses the same CPU as your laptop, and ... it's faster than my upgraded E6440!

Anonymous

Perhaps that acts a promotion strategy

John Rennie

08:18

Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

Bernardo Meurer

Also, Linux is way more accessible for a beginner developer. Developing on Windows is really daunting b/c people tell you to just use an IDE and it's crazy

On Linux you just call make/gcc from the CLI and go slow

John Rennie

@BernardoMeurer that is complete ~~bollocks~~ balderdash!

Bernardo Meurer

At least this is my own experience, from waaaaay before I even liked linux

John Rennie

I agree that people should learn to code at the CLI

But as soon as your project gets big using Visual Studio is vastly superior.

Bernardo Meurer

I use Clion myself

Agreed, I'm not telling people to never use an IDE

Iff I were on Windows I'm sure I'd use VS

John Rennie

08:20

And when it comes to debugging, using an IDE is basically essential.

Bernardo Meurer

My point is that, as a beginner, operating the POSIX CLI was faaaaaaar easier than the Windows variant

ALSO

John Rennie

But you can develop from the command line in VS. It has a command line compiler just like GCC.

In fact I usually use the command line for small apps.

Bernardo Meurer

@JohnRennie Yes, but it's not as easy to use, IMHO a beginner shouldn't even touch an IDE

IDE's are like giving a bazooka to a child

they'll blow their foot off and never want to play again

That almost happened to me!

John Rennie

@BernardoMeurer yes it is. Open a command prompt and type cl hello.c

What's complicated about that?

Bernardo Meurer

People should really start with gedit or w/e and a cli

@JohnRennie Hell, I've been a dev for a long time now and I did not know about that :P

I'm just talking anecdotes mostly, because this was the sole reason I moved to Linux

that I found developing on Windows to be overwhelming

John Rennie

08:24

@BernardoMeurer that's because you have such a downer on anything that isn't Open Source that you never look properly!

Bernardo Meurer

Again, I didn't even know what Free Software was back then, I didn't care

@JohnRennie Sublime Text isn't Open Source and I gave it a chance!

I just don't like Malware

John Rennie

I guess we differ on what constitutes malware

Anyhow ... back to the laptop.

It turns out that the heatsink in it is rated only up to TDP of 37W and the BIOS throttles back the CPU as soon as the power dissipation exceeds this.

Bernardo Meurer

Hmmm

John Rennie

The i7-4810 is a 47W TPU processor, and that's why it gets throttled back from 2.8 to 2.6GHz as soon as the load builds up.

If I watch it in HWMonitor I can see it boosting to 3.8GHz under transient loads, which is what it should do, but a sustained load causes the clock throttling.

Bernardo Meurer

Hmm

Can you modify the fan curve to make it more aggressive?

I've had to do that before, manually write to the fan controller's DMA

I do that at boot actually :^)

John Rennie

08:29

@BernardoMeurer well, it's harded coded in the BIOS. It would take considerable hackery ...

Bernardo Meurer

Hmmm

@JohnRennie Do you like Bossa?

I'm assuming no, since I know you loathe Jazz

John Rennie

Never even heard of him/them ...

Bernardo Meurer

Bossa Nova? The Genre?

John Rennie

But you're right, I'm not keen on jazz.

Bernardo Meurer

@JohnRennie Do you have a Spotify?

John Rennie

08:32

Ah, it's a genre. I've heard of bossa nova.

@BernardoMeurer no

Bernardo Meurer

God, you're like my dad

John Rennie

Facebook is the only social media site I use.

Bernardo Meurer

What, spotify isn't social media

It's a music streaming service!

John Rennie

Ah, yes, sorry.

Mixing it up with something else.

Bernardo Meurer

last.fm probably

John Rennie

08:34

I don't have a Spotify account because I prefer to get whole albums and listen to the whole album.

Spotify isn't really designed for that

Bernardo Meurer

It is if you pay :P

I honestly use it for one thing: Discover Weekly and Daily Playlists

I have found a lot of new music that way

John Rennie

I got the impression Spotify was really based around playlists of selected tracks, though I'm sure you can listen to whole albums.

Bernardo Meurer

I uses some creepy AI/ML to find you stuff you might like

Ah, no, you can listen to whole albums

Or whole discographies

Or playlists if that's what you're into

I mostly just find the album I want and listen to it end to end

John Rennie

I listen to the radio a lot. BBC radio 6 and a couple of weird Internet stations, and I hear new stuff through that.

Bernardo Meurer

e.g. open.spotify.com/album/60xmVPU5u2ABpEqi2g8ZIn

@JohnRennie I don't have a lot of patience for radio tbh, It's just bad SNR

John Rennie

08:39

A lot of the tracks on the radio aren't of interest to me, but I hear enough tracks that I do like to make it worth while, and the stations I listen to play a lot of new stuff.

But US radio has a poor reputation ...

Bernardo Meurer

Yeah, it's not very good :/

Anyway, you might want to give Spotify's 3 month trial a try

It's a nice service, and the music-finding algo makes it well worth it for me

John Rennie

We'll see :-)

Bernardo Meurer

Anyway, Bossa Nova is stuff like this @JohnRennie :

Pernambuco (Luiz Bonfa) (1959)

John Rennie

I've always liked music that has a weird edge to it. Something different and new.

Bernardo Meurer

Oh, I have just the thing!

Hermeto Pascoal - Música da Lagoa

John Rennie

08:45

Flutes are good. Lots of my favourite prog rock bands use flutes. But a whole album of flutes would get a bit dull.

Bernardo Meurer

Hmmm

What about this

Hermeto Pascoal - Mistérios do Corpo

►

I actually really like the crazy lagoon flute song

Specially when he summons the butterflies

@JohnRennie Anyway, before I head off to bed, try and listen to this album

See what you think

John Rennie

We'll see :-)

BAYMAX

Hey@JohnRennie

I am back again with Einstein!

John Rennie

back with Einstein?

BAYMAX

Like Einstein quotes and stuffs , works

There are so many questions and I hope you can help

...Lets start with a question that why Einstein is special? ... I got a point that he was able to connect the unconnected concepts!

John Rennie

Einstein's genius was that he could see how the physics worked. He wasn't a great mathematician, but he had an ability to grasp the physical principles that the maths needed to describe.

But it has to be said that this ability deserted him in his later years, hence he wasted the second half of his life looking for theories that we now know are non-starters.

Anyhow, I have to work for about an hour so I'll have to go offline. Back in about an hours time ...

BAYMAX

Sure

Anonymous

@JohnRennie He wasn't a great mathematician? Really?

Anonymous

I can agree he didn't discover anything "original" in mathematics.

Mr. Xcoder

How come Einstein not be a great mathematician?

Relevant.

Anonymous

@Mr.Xcoder Well, that's my question too.

Mr. Xcoder

I love the second answer to ^^

Balarka Sen

09:36

I have heard that story too (about Einstein not being a very good mathematician)

tbh you don't need to be a good mathematician to be a good physicist. I agree with what JR said

the fundamental principals of thinking are very different in the two branches

Indeed, I think being a good physicist might actually hinder being a good mathematician, and vice versa

Mr. Xcoder

Of course, Physics and Mathematics mindsets are very different, but coming up and solving with his brilliant equations of GR is not something a mathematician would be ashamed of

Bernardo Meurer

@BalarkaSen What if you're bad at both

What do I do

Balarka Sen

@BernardoMeurer Then you become a computer scientist.

Bernardo Meurer

lol

Mr. Xcoder

Not to mention he was a self-taught guy

Balarka Sen

09:40

@Mr.Xcoder Sure he did some nontrivial mathematical work in the physical cover-up. That's true for a lot of contemporary physics. Physics influences math in countless ways.

Mr. Xcoder

(mostly)

Balarka Sen

But that doesn't make physicists into mathematicians, is all I am saying

I am not demeaning anyone, just saying there's a distinct boundary between the various scientific disciplines

Mr. Xcoder

I concur

Balarka Sen

That being said, I think GR is pretty dope. I'd like to learn it at one point

Mr. Xcoder

Me too... sometimes in high school perhaps

Balarka Sen

09:44

How stupid can some professors be? ಠ_ಠ They selected a 10th grade thermodynamics exercise for an 8th grade Physics contest, gave full marks to a greedy and incorrect 8th grade approach and gave half the marks for the correct solution

... And the solutions they gave were wrong haha

Namely, we were asked to find the percent of water that vaporizes during a certain period, whilst they assumed the mass of the liquid water is constant

CooperCape

Xcoder if you can learn GR in highschool then you are fucking insane...

Mr. Xcoder

@CooperCape Oh, I meant to say after, not in... My bad!
