bofh, it's hard to articulate, but as I watched it, I realized it's absurdly good "food for the mind" in terms of how much math and physics are on display in it. I suppose it's not much different in terms of influence than is music alone. At the very least, I could understand how one could spend a lot of time thinking about spinning objects without even necessarily realizing it
<UmbralRaptor>
radvel is starting to seem like LaTeX in a bad way. Apparently I sometimes just need to run it a few times to get a result?
<SnoopJeDi>
UmbralRaptor, run LaTeX multiple times, you mean?
<SnoopJeDi>
oh nvm, I misread that
<UmbralRaptor>
run both, multiple times
<SnoopJeDi>
UmbralRaptor, is data written out to somewhere it'll be read on the next pass, or are random numbers involved anywhere?

I am not sure. let me check...
<egg>
Sarbian: also is there an easy way to set up a sandbox to eggsperiment with modulemanager without having to start the game
<egg>
(I guess I could write one, I'd need to load stuff into a GameDatabase and call MM itself, but if that is already a thing I can be lazy :-p)
<Sarbian>
We have test so I guess so. Blowfish rewrote so much that I am actually out of the loop...

stares at the 'fast' version of the Earthfinder analysis, where the number crunching will probably take close to 2 weeks.
<egg>
raptop: so we're looking at using the fancy azure machines to run our trappist deмcmc
<egg>
fancy as in the 72-core ones :-p
<raptop>
...
<raptop>
The cluster I'm using has 8 working nodes, each with 8 cores (and it makes sense to avoid using the main node)
<raptop>
I guess I can get up to 14 nodes with 8 cores on another cluster, but I'm sharply disk space limited there. =|
<iximeow>
raptop: unregistered hyperstar 2
<raptop>
hyperstar?
<raptop>
Ah
<iximeow>
that's the third-party replacemment secondary that starizona makes for celestron OTAs that .. have a removable secondary
<iximeow>
yeah
<iximeow>
(good news: 11" on a proper GEM works great. bad news: 86% humidity and 44f ambient temp means everything was coated in water.)
<raptop>
aaaa
<B787_300>
iximeow: why are you even trying at 86% humitidy
<B787_300>
also what was the dew point
<raptop>
I guess you could try putting on a heated dew shield
<SnoopJeDi>
egg, how many slots? The fell-into-my-lab machine I've been using is 72 physical cores on 4 Xeon sockets. It's nice
<B787_300>
silly thought... why isnt there an attachment that allows for the affixment of a hair dryer just infront of the lens in a SCT ? als long as the layer is realtively laminar across the surface you shouldnt be introducing that much more noise. and if you made it a digital system you could have the layer of air be like 2-5 deg F above the dew point to reduce the temperture gradient more
<raptop>
Not hair dryer power, but there are systems that heat that part of the scope.
<SnoopJeDi>
from the edges?
<raptop>
oh, misread. pushing warm air towards the center
<B787_300>
yep, might only work on smaller (sub Half meter) scopes
<B787_300>
pushing air all the way across the scope
<SnoopJeDi>
oh, so basically the same idea then, heh.
<raptop>
half meter is rather large for refracting parts, though.
<SnoopJeDi>
but less...hair-brained? :)
<iximeow>
B787_300: found out after the fact
<iximeow>
got there: "hmm it feels really humid, this isn't good"
<iximeow>
(note: "there" is "halfway back from meeting the seller", so it's not like i just went and wasted an evening, otherwise i would have been more careful in checking weather :P)
<B787_300>
iximeow: you were buying the GEM?
<iximeow>
the OTA actually
<iximeow>
the GEM was last week
<B787_300>
what OTA did you get
<iximeow>

<B787_300>
does it have a thermometer for auto correction?
<iximeow>
it does not (what does? o_O)

one of the focusers i used at school had a temp probe on it and auto corrected for temeprature

<iximeow>
oh i learned a funny failure mode in setting it all up last night (having not used a GEM before) - if you plug in the dec unit where RA goes and RA where dec goes, it doesn't point in the right directoin
<iximeow>
huh
<iximeow>
i wonder why
<B787_300>
what mount do you have?
<iximeow>
cge pro
<iximeow>
the cables are keyed so they can't be oriented in the wrong direction, but they're keyed the same, so you can uh, plug the wrong ones in
<B787_300>
how does that compare to something like the Paramount MX?
<B787_300>
(other than being about half the price of the MX+)
<iximeow>
all i really know is what i've read, which is that it's a good step up from a wedge-mounted fork, but not as nice about being remotely operated
<iximeow>
i imagine you're comparing new prices too :P
<B787_300>
yeah the CGE Pro is 5k, the Paramount MX+ is 9k
<iximeow>
yeah i paid ~2k
<iximeow>
i'm quite intending to rewrite half of celestron's software though, so i think in a year or so i'll be very pleased with it
<B787_300>
do you have decent weather conditions in whatever part of the world you are in?
<iximeow>
excellent conditions ~85% of the year
<B787_300>
lucky you
<iximeow>
the humidity issues earlier are more due to it having rained the prior day, and water still being in the ground

not just the j terms, tesseral (and sectoral) terms too

the latest release goes to degree and order 10

there's damping so that at long distances higher harmonics don't exist
