sounds legit

@enumaris Sodium, potassium and the "leak current" as Cl- Fundamentally, we know more about the behavior of the ion channels than we did in 1952. Carver Mead's 1989 book used the same notation; however, it's moved since then because in circuits we do not have "batteries" for channels. We have voltage-controlled current sources (FETs).

I think...I think I forgot the question I asked you to get that answer T_T

@danielunderwood does God forbid it

bloody hell it's hot

Mister Burns was right

We need to blot out the sun

@JakeRose I'm making a 1x1x1 cm cell, which is 100 times bigger than the original e-paper display cell.

I am a bit confused by QFT, would anyone be kind enough to explain this to me?

especially why a wave functional is the product of an infinite number of wave function? what is its physical meaning?

This thing called love I just can't handle it

Omg this chatroom is really REALLY dead

What happened :(

@NovaliumCompany Although I hadn't been here for a while, this bar seems to me still pretty cool

@Shing Instead of being an $L^2$ function on $\mathbb{R}^3$, it's an $L^2$ function on the space of schwartz functions

which can be very roughly described as $\approx \mathbb{R}^\mathbb{N}$

Errr wait

I'm thinking of Fourier series

not so here

hm

but well roughly you can express a wavefunctional as an infinite number of wavefunctions

Since there is some isomorphism between those and Fock spaces

As seen here, for instance

@Shing You rarely see more than 3 people online at once

@enumaris That's why we can reply to individual messages :P

@Slereah $L^2$ w.r.t. what integration measure? :P

@ACuriousMind The canonical one

obviously

-.-

Lebesgue and Ornstein–Uhlenbeck respectively

If you want to get FANCY

@ACuriousMind could have been worse

I could have answered $$\prod_i^\infty \mathcal{D}\phi(x_i)$$

@Slereah FANCY, aka "correct"

Like someone's gonna use... whatever other measure exists on $\mathbb{R}$

Although I guess technically all those Hilbert spaces are isomorphic

So you could do QM on them

@Slereah Can you actually prove that $L^2(\mathbb{R})$ is infinite-dimensional but separable for all measures?

Because otherwise they are not isomorphic :P

@ACuriousMind Well me personally, no

That seems like a tough job

But I assume some are

I have just bought myself a Chromebook, and I am very impressed with it.

£209 (about 209 Euros thanks to Brexit) and it's pretty fast. Browsing this site is just as fast as on my much more powerful desktop PC.

And it has support for running Linux apps built in as standard.

What's a Linux "app"?

Before you young whippersnappers took over there were only programs. These days I can no longer keep up with the terminology.

In this context app means something you created using your C(++) compiler.

Well...given that it's a Linux-based OS I'm not particularly impressed by that :P

@ACuriousMind ChromeOS is based on Linux but is heavily modified. That's why it can run Chrome so fast on low powered ARM CPUs.

It actually runs the Linux apps in a Linux VM.

@JohnRennie It's probably doing that more for security reasons than because it couldn't run them natively

Also, by setting up a Debian-like VM you get to profit from the established Debian package system

Whatever the case, it's seriously impressive.

On such a low powered CPU you won't be running big unix apps, but you have the option if you stuck away from your desktop and urgently need to do something that requires unix.

Reading up on it, it seems to be a Google-typical setup that straddles the line between genius and madness :P They don't directly start the Debian VM, they start a stripped down VM version of ChromeOS itself that then hosts the Debian VMs - that this performs remotely acceptably at all is already no small feat

Not really.

There is a builtin VM (called penguin - original) that is used to mount the Linux containers. But you aren't running a container in a container. Penguin just does the mounting.

@JohnRennie As far as I understood from here, they first create a read-only "Termina" VM that then hosts the Penguin container

> Termina is a VM image with a stripped-down Chrome OS linux kernel and userland tools. Its only goal is to boot up as quickly as possible and start running containers. (my emphasis)

I think that means "start the containers running"

Not "start, then run containers"

A note of realism is required - this is still a slow CPU with only 4GB RAM. But in practice it's really quick to use.

Anyway I have to go.

@JohnRennie I'm not sure what you mean - the containers are just containers, so they use a shared kernel, and if they are started from the VM the only kernel they should have access to is the VM's kernel.

← lol also tries to regularly straddle line between genius+madness... btw iirc old chat conversation between heather + bernardo to install linux dist on a chromebook... was impressed... also thinking of buying chromebook for cheap linux potentials :)

woohoo

our open-domain QA pipeline is completed BAM

just waiting for the UI to be coded...

@enumaris You got continuous integration w/ pull request and code review?

hah!

the software engineers worry about that

but I do perform the data-science analogue...continuous experimentation and experimental result review...

so what does 'QA' mean to you?

oh sorry

question-answering

not quality assurance

loool

::facepalm::

I forgot it can stand for other stuff

That's 'Q&A', not 'QA'! :P

XD

Our innovation center's grand opening is in 2 weeks

maybe you can get your manager to send you here and you can check it out ;)

(I'm guessing we are from different board areas though)

I'm P&I, but my manager is still on vacation for a bit :P

products and innovation?

aye

well we are off by 1 letter lol

T&I

I wasn't aware of the P&I board area...

wait

I might be T&I :D

Several of the recent renamings have been confusing :P

P&I is not a board area lol

yeah then we are the same board area :D

Yeah, I'm T&I

Jeurgen was originally gonna come to the grand opening...but then he canceled...

so was Bill...

*Juergen

oh

I was wondering which order the letter go...

It's not so easy because both 'eu' and 'ue' are German sounds

D:

I'm guessing you're under Jan in Central Engineering?

'ue' is a vowel and a workaround for non-ASCII 'ü', while ''eu' is a diphtong

that accent guy on Wired always mentions diphtongs...

@enumaris Nah, I'm core platform (upper management Harald -> Gunther)

oh

I can't even tell what the clear delineations in the board areas are...so...one more level down is like...eh...

well at least we are in the same board area...that's like a group of 6000/100,000 lol

close enough

I was just informed today that Monday is labor day so this weekend is a 3 day weekend

nice

lucky you

:D

Also I'm not sure what other tasks I should do...it seems I completed all my immediate tasks...

I guess I'll just default to read papers

learning some basics of MPI...seems interesting...

let's do distributed ML!

In the same way the rotor of the playground seems magical to me
