Anaconda the thing that keeps on giving whitequark problems?

I think? The Python one. Are there other Anacondas?

Anyway Raymond Hettinger asked if it would make sense to add `math.tau` to Python stdlib and I just *really* don't see eye-to-eye with τ

Ah, that τ.
<SnoopJeDi>
Maybe I'll be pleasantly surprised with a practical way to measure the radius of a hollow tube. Not that it'd stop anyone from using their calipers and dividing by 2...

I guess at some point it reduces to "circles don't exist" heh

<awang>
SnoopJeDi: Bacteria are too good at survival?
<APlayer>
What does "At 30 (sigma) significance" mean?
<SnoopJeDi>
APlayer, are you familiar with the normal distribution or confidence tests?
<SnoopJeDi>
awang, and not-bacteria!
<UmbralRaptor>
APlayer: the null hypothesis got stabbed.
<APlayer>
Normal distribution, yes. Standard deviation too
<awang>
APlayer: Basically if that thing happened by chance the authors should go buy lottery tickets
<SnoopJeDi>
Yea, interpret that as "if the null hypothesis were true, what we observe would be a 30σ outlier"
<UmbralRaptor>
SnoopJeDi, iximeow: As in do a flyby, but colliding not so much.
<APlayer>
So it means certain to within 30 std. dev.
<SnoopJeDi>
read as: the null hypothesis is not true
<iximeow>
UmbralRaptor: that "what" was at the observation, not the tesla :P
<UmbralRaptor>
ah
<iximeow>
i'm consistently surprised at what we can measure :P
<SnoopJeDi>
(recall the 68-95-99.7 rule for full width area under 1, 2, 3 σ)
<APlayer>
Alright, got it
<SnoopJeDi>
so 3σ is usually considered the cutoff at which you're very confident, except in HEP where 5σ is chosen fairly arbitrarily as the golden rule for discovery (after some large embarassments in the 70s)
<awang>
I thought HEP was 6 sigma
<SnoopJeDi>
err sorry 6 sigma
<SnoopJeDi>
(it kinda depends who you ask, really)
<SnoopJeDi>
I think 5 sigma was the golden number for Higgs
<UmbralRaptor>
Some fields go with 2 σ.

Because I am a lottery fan: I think I should bet my life savings that 'Oumuamua (how terrible to spell that) is, in fact, not a comet

SnoopJeDi: I'm not used to typing out "Ou" - "mua" - "mua", and I am getting confused because of it at 30 σ significance ;-)
<UmbralRaptor>
Technically 'Omuamua is a misspelling because Unicode has too many apostrophes and quotation marks.
<bofh>
I'm still kind of sad it didn't get named Rama tbh.

I love it when I post a really cool twitter thread, it goes viral, and as a result I learn something just as cool that I didn't know of earlier (that I now did a thread on as well).

Does Netscape even exist any more?

Also, since when could Acrobat Reader function as a web browser?
<UmbralRaptor>
I don't think there's been a release in a decade, and I don't want the answer. Respectively.
<UmbralRaptor>
Probably the site has lots of PDFs?

Better question: Since when could IE function as a web browser?
<bofh>
Since ~IE11 it's been *okay* at that.
<UmbralRaptor>
IE5 came out in what, 99? 00?
<APlayer>
Still used as the standard test sandbox - if it works in IE/Edge, chances are it works everywhere
<UmbralRaptor>
99

Netscape 7 was apparently 2002-4

I've heard Edge is mostly not evil?

I'm not touching it anyways. From the news I gather, the features they implement arrive a few years after other browsers had them

Is <marquee> not a thing anymore?
<SnoopJeDi>
It's long since deprecated

huh, MDN's page on it seems...wrong?
<SnoopJeDi>
"While some browsers still support it, it's not required."
<APlayer>
Aww, I was about to use it for my texts to save screen space
<SnoopJeDi>
HTML5 reads like <marquee> support is required, but discouraged.
<SnoopJeDi>
Triggers a warning in a conformance checker and says "Elements in the following list are entirely obsolete, and must not be used by authors:"
<SnoopJeDi>
so yea anyway nobody's used <marquee> in who knows how long. CSS got *really* good
