… this application requires I use Times for the font. Will I get stabbed if I use Computer Modern?

How important is the thing you're applying for?
<UmbralRaptor>
Six kilobucks over the summer.

Pretty good raise, then

Maybe the CM font that's closest to Times?

Or you can use Times with the LaTeX engine

OSX 10.13.latest, though that's theoretically a work computer.

I know Dolphin is one of the better emulators

SNES ones are fairly accurate too
<awang>
Just go on tasvideos.org and see what emulators they use
<iximeow>
UmbralRaptor: "system" as in the thing to emulate, i think
<UmbralRaptor>
Or Linux, though that means one dead system and one that's in storage because a 2007 netbook is not high performance.

SnoopJeDi: I spent quite some time trying to debug our CI. Turned out that tensorflow built on my laptop assumed AVX2 CPU instructions which the CI server CPU did not support.
<SnoopJeDi>
When I learned about Lorena Barba's group's attempts to replicate their own version-controlled results, I gave up on scientific software
<e_14159>
I did not hear about that.
<e_14159>
Do you have a link?
<SnoopJeDi>
Yep, very handy read and ref to give to people who are like "lol best practices are simple tho" https://arxiv.org/abs/1605.04339
<e_14159>
Best practices are simple, though.
<e_14159>
:P
<SnoopJeDi>
yea they just don't happen to work :P
<SnoopJeDi>
(always)
<SnoopJeDi>
that said yea it's still very useful for most of the low-hanging fruit
<e_14159>
They don't always work, or they always don't work? :D
<SnoopJeDi>
the former, of course :)
<SnoopJeDi>
just wait, NERSC is totally going to make their own Docker and that will definitely fix ALL of the problems :D
<SnoopJeDi>
(I do think containerization represents a happy prognosis for science...just not Docker)
<e_14159>
Reminds me of an issue my master's thesis adviser told me about: He tried to replicate some randomly generated stuff (had the seed). Except the MKL version changed, and therefore the result wasn't reproducible...
<e_14159>
Singularity?
<SnoopJeDi>
yyyyup that's basically what happened to her group
<e_14159>
SnoopJeDi: No spoilers! :-)
<SnoopJeDi>
it's only one of the Acts :P
<e_14159>
SnoopJeDi: Extremely interesting read, and it is quite eye-opening how difficult it is to really reproduce something.
<e_14159>
I have the advantage that, most of the time, ML doesn't actually have those big discontinuities, meaning that I should still get approximately the same results.
<e_14159>
OTOH, did you see the NIPS talk by Ali Rahimi?
<bofh>
e_14159: gods, I swear half the reason my master's supervisor put up with me so much is b/c I was good at being clairvoyant with numerics issues in failed reproductions... and yep, changing MKL ver (or to be precise, switching from stock LAPACK/QUADPACK to MKL) was one of them. :/
<bofh>
but yea, agreed 10000%, best practises are actually hard.
<e_14159>
bofh: I'm a computer scientist, I don't want to deal with issues in my abstraction.
<SnoopJeDi>
e_14159, nope not familiar but would love a link to stick on my to-watch
<bofh>
I'm a physical chemist (or chemical physicist, depending on day & mood), you think *I* do? :P
<bofh>
I often don't get the choice.
<e_14159>
SnoopJeDi: https://www.youtube.com/watch?v=Qi1Yry33TQE One of the things he mentioned was that, in one experiment, accuracy decreased from >90% to ~30% because they changed the floating point rounding for a neural network.
<e_14159>
bofh: Despair?
<SnoopJeDi>
e_14159, huh, that seems remarkably sensitive. Like something that'd stick out by looking at gradients or "fuzzing" inputs to see if they're stable?
<SnoopJeDi>
but then, I'm not a NN person
<e_14159>
SnoopJeDi: Yup, it's quite sensitive. The point of the talk, essentially, was that we have no clue how neural network training behaves, and it is more like "Alchemy" than science.

Whitequark: natural is integer range 0 .. integer'last

pretty sure natural numbers start with 1

And positive is 1 .. integer'last
<egg|cell|egg>
(Ada)
<whitequark>
oh hm
<whitequark>
Some definitions, including the standard ISO 80000-2,[1] begin the natural numbers with 0, corresponding to the non-negative integers 0, 1, 2, 3, …, whereas others start with 1, corresponding to the positive integers 1, 2, 3, ….[2][3][4][5]
<egg|cell|egg>
In French 0 is both positive and negative
<egg|cell|egg>
In English it is neither
<whitequark>
as I was taught, 0 is neither positive, negative, or natural
<egg|cell|egg>
This confuses me

whitequark: also fields do not need to commute in french, but they have to in english or german

this also confuses me; also the german word for field is cognate to the french word, and not to "field", for added confusion
