<bofh> That's pretty accurate, tbh.

<UmbralRaptor> B787_300: congratulations!
<UmbralRaptor> egg|zzz|egg: what is the minimum distinguishable distance from whitequark's avatar?
<egg|phone|egg> Which wavelength
<egg|phone|egg> Also, /me back to nominal operating temperatures! Sleepy though
<UmbralRaptor> pls use Jy, lupitudes, or AB mags, not Vega mags.
<UmbralRaptor> Yay, cooling systems are working.
<egg|phone|egg> Lupitudes? Are wolves involved
<UmbralRaptor> Uh, my current avatar uses SDSS g, r, and i bands.
<egg|phone|egg> UmbralRaptor: what is a lupitude
<UmbralRaptor> Something like AB magnitudes in Robert Lupton's work.
<egg|phone|egg> Luptitudes?
<UmbralRaptor> er, yes. luptitudes
<egg|phone|egg> Lupitudes seems to find some weird books in French involving werewolves

<egg|phone|egg> Midway between releases we get wolves yes
<egg|phone|egg> Probably Kahan
<UmbralRaptor> uh
<egg|phone|egg> UmbralRaptor: obviously the lupitudes is the absolute magnitude of a standard wolf lit by the full moon
<UmbralRaptor> proposal: werewolf summation
<egg|phone|egg> for divergent sums this seems appropriate

<UmbralRaptor> This feels like it should be an April 1st paper: https://arxiv.org/abs/1803.08425
<icefire> I wonder if theres a programming language designed around common typos made when writing C++
<UmbralRaptor> I thought that was why Python doesn't have semicolons or braces?

<egg|zzz|egg> bofh: are higher-order householder methods worth anything?
<egg|zzz|egg> also how do I error analysis again >_>
<bofh> past ~third order? not really, you need your function to have more and more nicely-behaved derivatives, your expressions get nastier, and basically computationally one fourth-order Householder iteration is not faster than two Newton iterations (for any function I've tried, at least) while being a much more complex expression.
<bofh> I mean it might be worth a try for certain functions, but I've never found them to be useful.

<bofh> SnoopJeDi: ROFL
<bofh> SnoopJeDi: admittedly I kinda can't stop laughing every time I see it.
<Raptop> SnoopJeDi: makes sense.
<Raptop> … how expensive are Householder functions, and do I need a mortgage to use them?
<SnoopJeDi> bofh, it's such an adorable story :)
<egg|zzz|egg> bofh: wondering about roots, you end up with some sort of strange rational function in the approximation and the number whose root you're taking in the end, no idea how the trade-off works out between more lower order iterations and fewer slower ones
<egg|zzz|egg> am I going to have to make a plot of 57 root finders as well as one for the integrators,
<bofh> so it very rapidly shifts in the favour of doing more lower-order iterations
<bofh> as early as fourth-order for me for most functions.
<Raptop> Apparently our telescope is getting an InGaAs IR sensor. Yay?

<bofh> I mean your bandgap energy there is iirc ~0.75eV, so that gives you an optimum absorption of uh
<bofh> !wa h*c/(0.75eV)
<Qboid> bofh: (h c (Planck constant-speed of light product))/(0.75 eV (electronvolts)): 1.65×10^-6 meters
<bofh> !wa h*c/(0.75eV) in nanometers
<Qboid> bofh: convert (h c (Planck constant-speed of light product))/(0.75 eV (electronvolts)) to nanometers: 1650 nm (nanometers)
<bofh> so far-IR, yeah.

<UmbralRaptor> Mathematicians: give colloquia on cool modeling techniques, forget to include any "real world" examples. (Note: they actually did some. Just forgot to include in the presentation)

<SnoopJeDi> no wait .ps
<bofh> ...thank you for reminding me of the times I had to do ps->pdf conversions in my undergrad for math papers >_>
<UmbralRaptor> Other silliness: a proposal to use high precision RV (1 cm/s?) on quasars to directly measure H_0. (As in, z will measurably change on decadal timescales!)
<UmbralRaptor> …why .ps, and not .dvi?
<SnoopJeDi> good point!
<bofh> I've never actually had a paper linked to me in .dvi format, thank heavens.
<UmbralRaptor> To be fair, there's a >95% chance you already have software that convert it to a PDF.
