egg|zzz|egg, I think you managed to catch it just as it went over Nashville. And it looks like at the correct time. Congrats, now check the behavior of Venus + Mercury and see if they cause an apocalypse in the far future. :P
<regex>
egg|zzz|egg, is the location over Earth correct?
<regex>
I can't tell, clouds are crazy good looking
<regex>
Holy shit, it is...
<bofh>
yes, it is.
<bofh>
goddamn.
<regex>
That is incredible. Great work.

ferram4: it is at the time of conjunction, which is the nominal time of the Чебышёв release :-p (we had determined that it was just off nashville at that time iirc)
<egg|zzz|egg>
ferram4: btw, Cayley is the first version to have an update reminder, it triggers at that time
<egg|zzz|egg>
ferram4: so if you're at the right place, playing KSP, you'll get a reminder popping up, and then the sun will go dark
<bofh>
nice
<ferram4>
egg|zzz|egg, It is a sign from our Lord Egg, "Update your fucking mods goddammit"

bofh: hm, now is there a combinatorially satisfying argument for that
<bofh>
that's what I'm wondering about
<soundnfury>
egg|zzz|egg: I don't know, but after a quick perusal of what Alpha says about the integrand, the series expansion at x=inf looks suggestive

bofh: how would you go about poking that eccentricity (or inclination) graph of retrobop with Fourier transforms
<egg|zzz|egg>
I seem to be seeing high frequency (up to 8 days) effects pretty well, but the obvious equationoftimey look of it is very low frequency, and there things look like shit afaict
<egg|zzz|egg>
hm maybe I'm misunderstanding the output of the discrete Fourier transform
<bofh>
so first off the low-frequency bit of it strikes me as being possibly a secular resonance?
<bofh>
but like, window the datapoints and then DFT/FFT them? no clue what window the astro folks use tho
<egg|zzz|egg>
bofh: I'm not sure how a DFT actually works though
<egg|zzz|egg>
so I might be doing something *really stupid*
<bofh>
egg|zzz|egg: it decomposes a given function (or matrix) into a sum over its periodic components
<egg|zzz|egg>
bofh: yes, I know what a Fourier transform does, but I'm confused by what the discrete thingy does; if I have a list with samples every hour for 5 a, what is the resulting list of complex numbers indexed by
<bofh>
side note: I'm pretty convinced at this point that Paypal customer service's voice menu system is literally designed by Satan Himself.
<egg|zzz|egg>
voice menu systems in general
<bofh>
true
<egg|zzz|egg>
so ν = k/(NT)?
<bofh>
yes
<egg|zzz|egg>
wait that can't be right, it would mean that the frequencies would range from 0 to about 1/T; ν = k/T perhaps, so that the frequencies range from once over the interval to every sample?
