it does but they usually stick pretty close to the chip, there's lots of covers so far this event

including a few wonderful metal ones

They played a great one at the end of TMNT. I never played it, so I was wondering if maybe someone had just accidentally started playing their own music hah

I think snakes, ask SnoopJeDi

galois is a sort of qboid replacement

yeah qboid, thats what i was thinking of

nice
<egg|zzz|egg>
mofh: is 𝑃^𝑛(ℝ) a common notation? I'm more used to ℝP^𝑛
<egg|zzz|egg>
then again the notation and typesetting of that meme isn't exactly usual or tasteful either

mofh: also integrating a (osculating) dt and i (osculating) dt gives me something nicely behaved and close to the mean elements, I might do that
<egg|zzz|egg>
(can't do that to find ω obviously)
<mofh>
egg|zzz|egg: yeah that's what I'd eggspect for a, mildly surprised that works for i but I guess that's reasonable.
<egg|zzz|egg>
but maybe to get e, via b? integrating e dt directly would be obvious bullshit, but b might behave well, and from mean b and a...
<mofh>
and yeah that'll catastrophically fail for ω
<egg|zzz|egg>
anyway ω has secular variations so what would you even get
<mofh>
Hrm, yeah, if a is nicely behaved then b feels like it should *also* be nicely behaved, and yeah.
<mofh>
you'd get garbage for ω, basically :P
<egg|zzz|egg>
mofh: the fact that mean a is lower than the min distance is somewhat disturbing
<egg|zzz|egg>
circular orbits are disturbing

e = -nan(ind) km (from integrated osculating a & b) okay some refinements may be needed,

SilverFox, egg|zzz|egg is right, galois is written in Python. There's not much custom stuff under the hood, it's a Sopel bot with a bunch of standard modules disabled and a few custom ones (!acr, !wpn, etc.)

ah, python

python's obsession with whitespace is dumb
<egg|zzz|egg>
mofh: the value from r_pe and r_ap is more smol (and closer to nominal) but likely morally very BS considering the extremely perturbed apsides (even with the spurious ones discarded)
