good meme
 
7:36 PM
That might make for a long game
The time it takes will be measured on the long line
 
@Slereah This
is pure poetry.
 
Man, I don't even like numerical simulations!
 
From arxiv.org/abs/0801.4589 so I might be a tiny bit biased.
 
Are you the KamLAND Collaboration
D. McKee
indeed
 
7:53 PM
@Slereah It gets worse than that. That paper is a follow-up with more data from a previous one, and it is better for three reasons: (a) more time means more data, (b) better calibration in the outer part of the detector means more data passes the cuts, and (c) better understanding of low-energy backgrounds means more data and makes the independent axis long enough to show more than one full oscillation. My long-term project for KamLAND was a big driver of (c).
So I'm a little fond of it.
 
8:17 PM
@diobuceulb hehehe

8:31 PM
@DavidZ ?!? its says comments disabled on deleted / locked posts / reviews on the bottom & doesnt allow comments

8:44 PM
@vzn That seems to be an artifact of the question having been migrated to meta and then closed. Since the status is "migration rejected," the comments are open instead on the original. I would posit that having a discussion in those comments isn't a great idea.
 
@DanielSank you may find the video link at the end of this answer interesting
@dmckee how come you work in such a small team?
 
@EmilioPisanty Just introverted, I guess.
 
@dmckee also, how's it feel now that that PRL is ten years in the past?
 
tfw you realize the stuff you wrote out had a sign error
 
(yeah, I know, that was a low blow.)
 
8:48 PM
$e^{+t^2/2}$ should've been $e^{-t^2/2}$...ugh
 
@EmilioPisanty I've been feeling a little bit like I've been exiled to Siberia, to tell the truth. Harken to the howling wolves.
 
@EmilioPisanty random question: is the phrase "exponentially improved asymptotic expansion" one you've run into?
 
@dmckee apparently Siberia isn't howling wolves all the time, though
my PhD supervisor tells tales of summers doing field work in Siberia in August in humid 30°C+ heat
with swarms of bloodflies to boot
 
@EmilioPisanty I imagine it would be. Loots of sun, lots of water small bodies of water.
 
A black fly (sometimes called a buffalo gnat, turkey gnat, or white socks) is any member of the family Simuliidae of the Culicomorpha infraorder. They are related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 2,200 species of black flies have been formally named, of which 15 are extinct. They are divided into two subfamilies: Parasimuliinae contains only one genus and four species; Simuliinae contains all the rest. Over 1,800 of the species belong to the genus Simulium. Most black flies gain nourishment by feeding on the blood of mammals, including humans, although the males feed...
 
8:53 PM
On a completely different topic, I've just been tinkering with the tufte-handout as an alternative to revtex4-1 in formatting my short treatments for students. In at least some case it is very nice.
 
these ones, I think
@dmckee ugh
tufte is overrated
@dmckee sample?
 
Well, so far I've only tried it with a couple of notes that need lots of little figures and encourage a lot of side-comments.
I'm a little worried about how it will look with some of the other notes.
 
@EmilioPisanty The nofont class option makes it fall back on Computer Modern, and so far I've stuck with that.
@EmilioPisanty Yeah, that.
 
@dmckee meh
 
8:55 PM
 
I've developed a mild allergy to Computer Modern
 
^ What it looks like for my short blurb on heat engine basics.
The figures in the margin really work for that one.
The one about thermodynamics at phase-changes is less pleasing because I need a couple of big figures.
@EmilioPisanty I haven't been able to work up the energy to really experiment with fonts recently.
 
I'm super chuffed with my latest take on \documentclass{article}
but it doesn't look like I have a shareable draft
 
vzn
@rob (sigh) ok thx for info
 
@dmckee there we go
oh, also, I meant to ask
physics.stackexchange.com/posts/392736/revisions this feels like stuff that's appeared before
have we got a persistent potato-banana fan spamming us from time to time?
 
9:09 PM
Cool drop-cap, there.
 
@dmckee yeah, that took a while to get right
 
What are the fonts?
 
\usepackage{tgheros} %% Main sans-serif font
\usepackage{tgtermes} %% Main serif font
and for the drop-cap
%% Fancy first letter
\usepackage{lettrine}
\pdfmapfile{=montserrat.map}
\renewcommand{\LettrineFont}{
  \fontfamily{iwonal}\fontsize{42}{42}\selectfont %% Iwona Light
%  \fontfamily{Montserrat-LF}\fontseries{l} \fontsize{42}{42}\selectfont %% Montserrat light
%  \fontfamily{Montserrat-LF}\fontseries{l} \fontsize{41}{41}\selectfont %% Montserrat extralight ?
%  \fontfamily{Chivo-TLF}\fontseries{l} \fontsize{42}{42}\selectfont %% Chivo light
  \color[rgb]{0,0.25,0.8}
  }
%% use as \lettrine[lines=3]{T}{\,} he
I think the chivo version was slightly nicer but there just wasn't any way to install it on my texlive system
(that's TeX Gyre Termes and Heros, respectively, for the main text.)
 
9:22 PM
@vzn huh that's weird, I see the "add a comment" link as usual
@dmckee @rob how about you, do you see the commenting link on that meta post? I wonder if this is different for mods vs non-mods.
 
@EmilioPisanty OH MY GOODNESS!!!!
YES
So much yes.
This is exactly what happened in my field.
 
@DavidZ I see a link to let me comment.
 
@DavidZ I see 'comments disabled on deleted / locked posts / reviews'
 
The paper I shamelessly linked in my comment on that same post had the following essential message: You have to lift the two level approximation and the RWA in order to understand superconducting qubit readout.
@EmilioPisanty My colleagues are going to find this hilarious.
 
9:27 PM
@DanielSank if it earns me bragging points, I helped organize that workshop
 
@EmilioPisanty Excelent.
I just mailed that video to my team. It's funny.
 
@EmilioPisanty cc @dmckee huh, OK then, I never noticed that particular difference.
 
10:00 PM
@DanielSank ah, yes, here it is
That's me receiving the Sir Peter Knight Prize ::grin::
 
10:17 PM
@EmilioPisanty Wow!
Is that Mercedes in the bottom right?
Small world.
 
@EmilioPisanty Are you a giant or does it just look that way in the photo? ;)
 
o/
Long time no talk, people
 
Hey there @Danu
How's it going?
 
So many oldies here today! :D
@ACuriousMind I'm doing alright... Dealing with some personal issues but in general Hamburg is a pretty nice place to live, and work is OK too.
You happy in your job, still? :)
 
@Danu Yes, it's great :)
 
10:21 PM
Cool!
Today I stayed at home, alternating between chess, Fortnite, and preparing a talk I suddenly have to give in a few weeks' time on geometric quantization(?!)
 
Ah, student life where you spend weekdays at home. Not sure I miss it, I've gotten used to going to work more quickly than I thought
 
Heh, yeah... Nobody checks if I'm in the office, ever.
Turns out my supervisor is also pretty hands-off... I only meet him if I ask to.
 
I spent the day learning about performance analysis tools which would have been much more useful the day before when I actually had to analyze a problem in a customer's system :P
 
@Danu Hi!
 
hi Daniel
 
10:26 PM
@ACuriousMind I assume you can work from home if need be, or are you onsite with clients? A friend of mine who used to work for SAP seemed to be consulting all the time.
 
@alarge write a book on random processes.
Please.
 
@ACuriousMind Yea... Sounds like a classic move order problem :-)
 
@alarge I can work from home if I want, up to a maximum of 20% of the time. But right now there's so much I still don't know and need to ask more experienced colleagues about that that doesn't strike me as a good idea
 
@DanielSank You do that; you know more about the subject matter than I, I expect
 
I'm happy keeping myself busy with basic results in sheaf cohomology :-)
 
10:28 PM
And I don't do consulting...but if there's something going wrong with "my"/my team's code somewhere that support can't solve we occasionally have a look ourselves
@Danu That's nice
 
@ACuriousMind VTune was just made free the other day I think. I guess if that's the sort of performance tuning you do, you'd already have a license at work anyway, but oh well.
 
@alarge It's all ABAP code, and the ABAP systems have all the right tools already baked in, you just need to know where to find them.
I'm not in a position where I could install additional tools on a system
 
@ACuriousMind well, Peter Knight isn't the tallest man ever
But yes, I'm pretty tall
 
@ACuriousMind First time I've heard of ABAP. At quick glance (wikipedia) it looks like COBOL or something?
 
Anonymous
@ACuriousMind What type of work are you primarily involved in? Data analytics?
 
10:31 PM
@DanielSank indeed it is, that's some MRes event or other
Possibly a Christmas party?
 
@alarge It's SAP's own programming language that started in the ancient past as a sort of COBOL dialect and has evolved into something...different.
 
@ACuriousMind It is, really :-) I going through the explicit isomorphism of $H^2_\text{dR}$ with Cech cohomology.
 
@Blue Static code analysis, i.e. writing code that runs over other people's code and tells them it's bad ;)
 
@ACuriousMind Is it a nice language to work in? I have almost zero experience with SQL and databases and such, so I don't think I'm really in a position to say
 
@alarge I thought you've answered several noise questions that I've posted.
 
Anonymous
10:33 PM
@ACuriousMind Best job....ever :P
 
@ACuriousMind Do you read a lot of category theory, now, then? Not sure if it's super helpful for parsers, but if you have proper typing in the language...
 
@alarge The integration of the Open SQL dialect directly into the language is nice, and nowadays it doesn't look as COBOL-like and verbose as it used to. I don't love it, but I don't hate the modern variant, either. The legacy code is a different matter, though...
 
I wonder how relevant category theory is to any actual problem solving with code in day-to-day situations.
 
@alarge It's somewhat strongly and definitely statically typed, but I haven't really had to engage with the type system in depth yet, and I have my doubt category theory would enlighten it. Category theory is for Haskell ;)
 
@DanielSank I answered a couple, yeah, and I spent some time thinking about physics.stackexchange.com/questions/319989/… when it was new, but I think I never got to an answer.
 
10:37 PM
@Danu Haskell has functors and monads. But then again, it's a niche language
 
@ACuriousMind Well I wouldn't really call Haskell niche coming from ABAP :)
 
@alarge You really don't want to know how many million lines of ABAP code are keeping various large companies running ;)
It may be niche with regards to the amount of people that actually know it, but not with regards to its impact
 
I was recently forced to use some kind of programming when setting up my personal homepage on the university website
 
"some kind of programming" :D
 
@ACuriousMind tiobe.com/tiobe-index oh wow, it is actually above Haskell on Tiobe
 
10:40 PM
HTML... I guess it doesn't count for all you pro's
 
@Danu That's a document description language, not a programming language ;)
 
WELL IT FELT LIKE PROGRAMMING TO ME
2
 
In fact, I'm spending quite a lot of time on mathematica recently
I really dislike that
 
You're computing sheaf cohomologies with Mathematica?
I'd dislike that, too ;)
 
10:45 PM
No, luckily not haha
My main project is some really down-to-earth differential geometry
 
@alarge I need to tell KyleKanos that it's above Fortran the next time he pops in :D
 
I'm computing the isometry group of some Riemannian manifold... And that does feature mathematica.
 
Ah
@Danu "down-to-earth"...how many dimensions are you working in?
 
$4n$ :D
quaternionic Kähler manifolds
 
Ah, yes, salt of the earth, those quaternionic Kählers :D
 
10:55 PM
The true proletariat
But really, it's stuff any master's student with 2 courses on differential geometry could understand.
 
@Danu Perfect for you, then!
(I jest, I jest)
 
Cry evrytiem
 
Is it at least nice geometry any master's student could understand, i.e. do you like it nevertheless?
 
It's a little bit tedious, to be honest. I was never the biggest fan of this rigid Riemannian stuff.
But the results will be nice when they come (and they are essentially guaranteed to)
Plus it's good to learn how to calculate things, I guess
 
Rigid Riemann and Lenient Lorentz sound like a comedy duo
 
11:04 PM
Keeps you grounded and sure you can do something :)
Lol
 
@Danu Yeah, one shouldn't underestimate that!
 
Also, my supervisor is kind of the grand architect of the whole story that I'm working on developing; he proved all important properties of most of the constructions involved. It gives a safe feeling!
And I'm also really enjoying certain things outside of academics
I've taken up chess more seriously
 
@Danu Online or in a local club?
 
I play in a club now, too
 
nice
 
11:07 PM
I already played a lot online over the past years
(still do)
 
I remember ;) Still not my kind of game
I've just got a regular board gaming group that usually meets once a week
 
You guys also play chess?
 
@Danu Nope
Someone brings a game suitable for 3-5 players, then we play it
 
Ah, just this RPG thing right
 
@Danu No, the RPG groups are a different thing altogether ;)
 
11:18 PM
4-player chess :D
 
I guess if the week's game bringer insisted on that we'd play it :D
 
11:40 PM
Fair enough ;-)
 
11:55 PM
Howdy :)
 
o/
I gotta go, bye guys
