@BernardoMeurer My core clock doesn't seem to be increasing at all.

@0celoñe7 Dunno what's up then
try the EVGA thing
maybe you need to fix the clock
GPU Boost might be messing things up

@BernardoMeurer Yeah, trying
I can't find the serial number
to use the EVGA software you need a serial number

On the box

@BernardoMeurer It's behind the wifi card -.-

I mean the cardboard box it came in

12:10 AM
ah, it's there too
the sticker on the GPu itself is covered by the wifi card

Sometimes it comes on the box

yeah it was on the box
Ok, so let's try to do it in the software...
@BernardoMeurer Still nothing
It's actually underclocking now

No.
@BernardoMeurer hmm
It crashed, not coming back
@BernardoMeurer CPU crashed!

Weird

12:20 AM
@BernardoMeurer I tried to do a 300 MHz overclock past the boost clock

Lel
savage

I mean 300 so it would go pst the boost clock
I don't understand this. The EVGA software says the boost is like 1800 but I get 1950 in games

GPU Boost 3.0 does weird things
England is my city

@BernardoMeurer I can't figure out what to do

Call Nick Crompton

12:25 AM
That doesn't really help...

@BernardoMeurer My clock speeds are already higher than their overclocks...

I don't have a GTX 1080
In fact I never owned a single NVidia product

I wish they gave benchmarks at those clocks
@BernardoMeurer Ok, pushed the clock to over 2GHz and got a measly 2907 on Heaven

I have no clue what those scores even mean

12:36 AM
people on reddit are reporting 3000+
@BernardoMeurer Are you supposed to report twice the memory clock? People are reporting a memory clock exactly twice of mine.

Huh
I dunno
that's very weird

I dunno
best not mess with it too much until I get a 144Hz monitor

@JohnRennie Good morning

Hi. Long time no see.
Have you made it to the US yet?

Not yet, currently in Rio
Been away recently, moving took a lot of my time

When do you start at, err, I've forgotten which college :-)

Had to leave all my sound system behind with my gf who'll ship it to california directly
SBCC :P
07/08
I leave Brazil on the 4th

Santa Barbara?

4:32 AM
Yessir

@BernardoMeurer Seems to be stable at 2025 MHz

@0celoñe7 That's a nice OC

@JohnRennie breaking computers is fun!

@0celoñe7 you still in search of the ultimate fps? :-)

@JohnRennie Your amplifier is going to travel the world :P
After so many years

4:34 AM
Hmm, I wonder how it will work on US voltage ...

@JohnRennie Yes...AC Unity forced my hand.
There is something very wrong with my internet.

@JohnRennie Worst case scenario I get a transformer

Computer PSUs use switching circuitry so they don't care what the external voltage is, but I'm not sure about the amp. Try it and see I guess.

@JohnRennie It seems I can now stay above 60fps without fail with max settings.

It won't do any harm. At worst it simply won't work.
@0celoñe7 congratulations, your life is now complete :-)

4:36 AM
@JohnRennie No...I might buy a 144Hz monitor.
Then 144fps will be my goal.
The true masters manually edit the GPU drivers to get optimum performance.

In the early days of Windows 3.0 I recompiled the VGA drivers to change their properties. I'm not sure I'd want to try modifying NVidia drivers though ...

NVidia binary blob drivers are a mess
@JohnRennie I finally gave up on bumblebee and optimus with proprietary nvidia malware
Back to Open Source Nouveau drivers
works perfectly

@JohnRennie according to the internet I should be able to squeeze another 7% out of my GPU!
Not sure how these maniacs are doing it
Some people are overclocking to 2150 but that instantly crashes my system

How's the temp?

Below 70

4:45 AM
@BernardoMeurer have you used the GPU on the laptop to do calculations?

Not as much as I'd like
OpenCL is kind of a pain
and CUDA is malware

@BernardoMeurer Suppose I want to increase the clock...what should I change the memory to?

@JohnR: I watched Dunkirk twice; in the evening, I didn't actually feel like screwing around on my own at home while the others were away so I accompanied them and watched Dunkirk another time while they watched the Malayalam movie.

You liked it that much?

user228700
I did, yes. I didn't really want to watch it another time on the same day but I did and watching it the second time around was a completely different experience.

"Researchers Discover "Angel Particle" Which Is Both Matter And Antimatter At The Same Time"

The first time I watched it, it struck a chord emotionally. The second time, it was more of an intellectual experience; I kept questioning exactly why they chose to make a certain edit etc.

user228700

Couldn't possibly watch it a third time though.

Dunkirk was part of modern British mythology when I was a child, though I think it's now fading from memory.

@Kaumudi.H you might find this interesting, it answers a huge question that was on my mind lately after reading other movie reviews of Dunkirk http://www.thedailybeast.com/the-mystery-left-out-of-christopher-nolans-dunkirk-‌​why-didnt-hitler-go-in-for-the-kill ps my uncle was here https://en.wikipedia.org/wiki/Omaha_Beach

@Slereah Stanford article on the Majorana fermion. Note that it's a quasi particle.

user228700
@vzn: Wow! Omaha Beach being the one in Saving Private Ryan, right?

6:23 AM
@JohnRennie I did, yes

@Kaumudi.H yeah, the second watching is usually that way for me also.

@Slereah I knew it was a mistake to let the condensed matter guys start playing with QFT :-)

Anyone else suddenly thinking about Tina Majorino?

No :P

Ah, but you are now, right @skullpatrol?

6:38 AM
I had to look up the name pal :-)

Really? You don't remember her version of Alice in Wonderland?

Nope.

But it's a classic!
OK, never mind. Also, I think maybe I enjoyed Big Love far too much.

Dunkirk looks like a good movie.

Oh definitely. It's certainly excited Kaumudi.

user228700
6:47 AM
@skullpatrol I see :-)

7:08 AM
@JohnRennie I really hate how the meida gone so overhype with quasiparticles and then pose them as if they are real particles
Sure, they are interesting, but until they found an elementary majorana fermion, (insert suitable sentence to complete the sentence)

The media are prone to that sort of thing. It's just one of the things we have to live with. But the quasiparticles being found in condensed matter studies are very interesting. It's only a few months since Weyl (quasi)fermions were reported.
Right now there seems to be a lot of exciting stuff going on in the condensed matter area.

It is amazing how a lot of exotic particles in our theories can be simulated in condensed matter systems. Nature must be really love infinite number of coupled harmonic oscillators

Finding an elementary Majorana fermion would be ... well ... a bit interesting :-)

Hmm, Let me check the current list of particles we have simulated in condensed matter systems:

Dumb holes
Magnetic monopoles
Skyrmions
Weyl fermions
Majorana bound states
Negative effective mass
Chiral majorana fermions

Probably a lot more I forgot
(and I am pretty sure the list is in choronological order)

What are "quarks of a proton"?

7:18 AM
u u d?

18 hours ago, by Secret
maths chat is currently occupied by 3 users which are quarks of a proton

O, that's a metaphor saying how the 3 are engaged in a heated discussion akin to how the quarks are bound by the strong force within a proton
that any attempt in separating them will most likely form mesons and jets

I see.
yeah, it was pretty intense

One of the most well known ability of mine among my friends is the ability to said a paragraph of seemly academic or monotone stuff where every sentence is actually a joke or metaphor, back to back

That's an interesting analytical ability to have :-)

The answers below explain why sugar dissolves faster in hot water by saying that it has more intermolecular spaces and the other answer says hot molecules of wat...

the tag
the ************ tag
@Qmechanic I gather that the intention was that questions like the above would go to general-physics, reditected to please-remove-this-tag, and we would detect them that way?
Seriously, let's just burn general-physics with fire

@EmilioPisanty I think something in the tag system doesn't quite work as Qmechanic expected, since when I type "general" into the tag box, only the +tag appears
But, yes, I agree with the general sentiment of just getting rid of that tag altogether

My biggest issue with that question is that OP changed the question completely after receiving three answers. It's now an entirely different (and comically nonsensical) question. There should be some mechanism to stop people doing that.

@ACuriousMind well, that'll be because there are questions tagged but no questions tagged , so as far as the system is concerned, the latter does not exist at all, thus there's no reason to suggest its use.
@DawoodibnKareem Roll it back and instruct OP to ask a new question with the new question.

10:12 AM
@EmilioPisanty ACuriousMind just rolled it back. Possibly as a result of my comment.

@DawoodibnKareem Thanks for noticing that. As Emilio says, the mechanism to deal with this is rolling back and asking OP not to do that (as I just did)
In cases where OP insists on doing so after being told not to, we usually either lock the question or suspend the user, depending on the exact circumstance

I simply remove the perpetrator from my Christmas Card list.

@DawoodibnKareem That's a tad too cruel for me I think

@ACuriousMind Don't worry. I haven't removed you.

Seriously, though what else needs to happen before general-physics can be Death-Star-ray'ed into oblivion?

10:15 AM
What makes removing the tag so difficult? Is it because questions have to have at least one tag, and there are questions out there that fit no other category?
Honestly, maybe all such questions should be deleted. If they're not on topic in any other tag, then they're not on topic.

@EmilioPisanty Wait a moment, there are currently only 35 questions tagged with it. So we don't need to request burnination - we can just untag the tag from these questions and let the system remove it on its own
If the issue is that someone would recreate it, burnination doesn't stop that, either

@ACuriousMind so how does one go about blacklisting a tag?

15

A Stack Exchange site I use has identified a tag that should be blacklisted, discussed it on Meta and come to an agreement that it should go (our request is here). We and the site moderators understand that only SE devs can blacklist a tag. What we're not clear on, though, is how they expect us ...

Heyo ACM

@Danu hiya

How's the thesis coming along

Ugh (pretty complete description of my feelings about that currently :P)

I don't think anybody would dare to recreate it after some of the dark imprecations about it that I've seen in this room.

hahahaha

@DawoodibnKareem You should never forget that chat is a relatively tiny corner of the site and that most users are not aware of any discussions held in here

Self-censoring?!

10:25 AM
@ACuriousMind Probably just as well. And I was only half serious.

@Danu What? No, I edited my line into the original message because @DawoodibnKareem snuck his message between my two :P

Hahahahaha
I thought you actually referred to Dawood's message, which would've been a lot more hilarious.

I too thought that's what ACuriousMind meant.

lol

From Stack Overflow today. "... everything works perfect and I get my result but in the same time I get a Nullpointer exception ..."
How can "everything works perfect" and "I get a Null Pointer Exception" be part of the same sentence?

10:28 AM
@ACuriousMind OK, I'll start whittling them down, then.

@ACuriousMind I'm currently on cloud 9 because I finally found a PhD position... hence procrastinating instead of doing my thesis again haha.

hiya @Qmechanic

@EmilioPisanty : Yes, exactly.

@Danu Well done!

Thanks.

10:30 AM
@Qmechanic yeah, that... didn't happen =|

@EmilioPisanty : Testing.

@Danu I saw that and imagined you'd be exhilarated :D I have no idea what I'm gonna do yet

@ACuriousMind Did you see the profile of the person who asked about the dissolution of sugar, and the difference with salt?

@DawoodibnKareem No, I didn't look there. Why?

He or she claims to be a high-school physics teacher.
I'm a little staggered.

10:37 AM
@ACuriousMind Have you applied anywhere?

Reason dissolves in hot water? That actually explains lots of things. — Emilio Pisanty 28 mins ago

hehehe

@EmilioPisanty That is probably the origin of the German idiom "You must've been bathed too hot as a child" ;P
Hm, can one even use bathe in that passive form in English?

Ooh, don't joke about that. I went to school with someone who fell into very hot water at a very young age, and had permanent skin damage all over.

@ACuriousMind Yeah

10:41 AM
@DawoodibnKareem It's not really a joke - that is a common, if somewhat old-fashioned German idiom that one usually says about people who just did something very stupid.

@ACuriousMind Yes it's fine grammatically. But you'd really only use it for a very young child, or possibly a disabled or old person. Basically anyone who can't bathe themselves.

Qmechanic has made a change to the feeds posted into this room

@ACuriousMind Right. I guess many English speakers would say "you must have been dropped on your head as a child" or something similar. Which is equally unjokeworthy.

Then again, taking every joke seriously makes life boring too.

@Danu Yes, and the only positive responses I've got were of the type "I'd love to offer you a position but I ain't got no money." :/

10:42 AM
No positions at Heidelberg? :\
You might try the group that I found a place in... They have money. I don't know if it suits your interests though.

@DawoodibnKareem Which is why it would be much funnier if the origin was that reason dissolved in hot water ;)

My impression is that either (i) your supervisor keeps you, or hooks you up somewhere else, or (ii) you need to get really lucky.

Hm, my new chat room feed is for some reason not activated by my tests. @David Z : You have previous experience with making feeds. Can you (without spending too much time) see if something is wrong with my feed code format?

@ACuriousMind I think it requires hydrogen peroxide.

@Danu Yeah, that's seems pretty accurate. :P

10:49 AM
And yours is as unhelpful as mine? :(
(not to say I don't think my supervisor is super awesome... It's just that he doesn't seem to care too much about my non-mathematical problems)

@Danu Well, he can't keep me 'cause no money (unless I manage to get another scholarship) and I wouldn't say he's unhelpful, just nothing much has come of it.
Doesn't help that I'm not 100% sold on wanting to stay in academia anymore, so I'm also contemplating other options.

Damn, that's really unlucky. For my friends, it always worked out if the supervisor pulled some strings.
@ACuriousMind Hmm... That's a whole 'nother decision. And a difficult one.

@Feeds @Qmechanic I don't think that will work

Anonymous
@ACuriousMind Which "other" options? (if you don't mind)

@Blue Mostly software development (I know some people who went into that and there are several large software companies near me)

@ACuriousMind Well, what do you want to be doing five years from now?

@DawoodibnKareem that's the question, isn't it? :P

Once you leave Academia, it's very hard to go back. But if you want to pursue a software development career, that's perfectly fine.

@Qmechanic @rob @ACuriousMind is this the way to rephrase this discussion?

This has bothered me for some time, and since bad tags are on the table, I think this is a good time to do it. The original burninate request got good traction, and all that remains is to implement it. The general-physics tag is absolutely terrible, because it adds absolutely no information. It ...

@ACuriousMind Oh. Software developing is a rewarding career (monetarily). However, I wonder how much of your physics and mathematics knowledge will be put into use there. :/ Anyhow, a mathematician like you will obviously have enough analytical skills to get into such a job. BTW did you think of any options like Quantum Computing (I know a few startups coming up in that area) or something like that which will utilize your physics skills as well?

@Kaumudi.H: you around?

@DawoodibnKareem I know (neither of my parents have a PhD, or indeed any academic degree, and I wouldnt call their lives unfulfilled)
@Blue The issue is that, at the end of the day, I don't find physics - except for the really theoretical stuff - all that interesting :P

I have to say that I think you may have a lot of potential as a researcher.
Why not do some string-math type of stuff?

@ACuriousMind If that's truly the case, then a PhD in physics seems particularly pointless.

@ACuriousMind: what would you do? Look for a maths PhD, or become a quant and make shedloads of money?

11:04 AM
Why not do some string-math type of stuff?
The group is Hamburg has a really great mix of things going on. Physicists doing math, mathematicians doing physic(ist)s, and lots in between.
I have some specific recommendations for people to look at if you are at all interested (I know for a fact they are looking for students)

@ACuriousMind I see. Oh well, then a computer science career would be the best use of your mathematics skills. :) You'll earn a ton as well. :D All the best :)

@DawoodibnKareem Well... :D

@Danu Well, that is the sort of thing I would like to do as a PhD. I'm not saying I don't want to do that. But I'm also not really sure anymore if that's something I absolutely want to do, and sacrifice everything else for it.

Don't expect to use any really heavy mathematical skills as a computer programmer.

@Qmechanic I'm really confused about the strong pushback against burninating general-physics.
There's very clear support on meta going back almost four years.
The alternative is manual removal which is much more harmful to the front page.

If it's the feed, it seems okay - there is only one question with the tag currently, and I don't think we'll see the feed in action until a new one appears

@DavidZ : Yes. Well, I tested it with 2 questions: One 1h old and another very old. But no feeds were generated. (I deleted the tags again after 10 minutes).
