* UmbralRaptor blinks at twitter https://photos.app.goo.gl/bsWdvjKu6uSkDi7h9
<SilverFox> so I was talking with an engineer today
<SilverFox> and I'm not good at maths, but he was all up in that matlab stuff after I showed him the glory of ternaries
<SilverFox> and we got into matrix ops, and I'm curious if C,C++, C# has the things that matlab does for the matrix ops that matlab has
<SilverFox> and that unity's Vector3 * Vector3 isn't a matrix multiplication, but like an addition or some shit idk?
<UmbralRaptor> The C-like languages probably have relevant libraries *eyes the floating point cat*, though I'd feel safer saying that they exist in numpy. Also IDL for some reason.
<UmbralRaptor> Hrm. The actual channel mathematicians seem to be asleep or afk.
<SilverFox> rip
<SilverFox> oh, just so I understand properly, a matrix multiplication of A being a 3x3 matrix of all 3's, and B being a matrix of all 2's, this would result in a 1 by 3 matrix of 16's, correct?
<UmbralRaptor> uh
<egg|anbo|egg> UmbralRaptor: afk
e_14159 has joined #kspacademia
<egg|anbo|egg> UmbralRaptor: i am not asleep but should be, bofh probably eggsists and might still be able to answer questions
<egg|anbo|egg> i otoh am tired
<SilverFox> egg needs sleep for grow
<SilverFox> won't become a pretty butterfly otherwise
<UmbralRaptor> Probably? ‹bofh|bofh› < 1?
<SilverFox> if something is 'null' it's treated as if it doesn't exist, correct?
<egg|anbo|egg> UmbralRaptor: btw lagoon nebula was a good idea and was cute; we also looked at the trifid nebula, not really any visible nebulosity there, though open cluster next to it (Messier whichever)
<UmbralRaptor> SilverFox: I think there's an unstated assumption about B's dimensions. Also, the addition seems off?
e_14159_ has quit [Ping timeout: 202 seconds]
<UmbralRaptor> egg|anbo|egg: Yay. fwiw, there's lots of stuff at +dec from there (omega nebula, eagle nebula, wild duck cluster…)
<egg|anbo|egg> UmbralRaptor: yeah but in bed because tired, also mild clouds
<egg|anbo|egg> UmbralRaptor: bofh might be able to answer numerics questions
<bofh> tired: amphetamines as exclusively ADHD medication; wired: using amphetamines to stay up for 4 days in a row for conference; inspired: using amphetamines for Bonus Mydriasis to boost dark adaptation (shockingly it *did* help a bit, not enough to recommend to others just for that purpose tho :P).
* UmbralRaptor is amused at how egg has both cats sleeping next to eachother.
<bofh> 22:03:22 <@SnoopJeDi> bofh, egg|anbo|egg, if I say to you "random packing of (uniform) spheres in a spherical shell," what's your first optimization intuition?
<egg|anbo|egg> UmbralRaptor: yes
<UmbralRaptor> bofh: wait, you can use amphetamines for *dark adaption?*
<egg|anbo|egg> UmbralRaptor: also bofh is sleeping with one of the cats i think
<SilverFox> UmbralRaptor, I was told it goes the 333 matrix against 222 is that each 3 is multiplied by the 2, so 6 + 6 + 6, which is 18?
<UmbralRaptor> Yeah, 18 makes sense. 16 did not.
<egg|anbo|egg> bofh: also demoscene really sounds like a geologic period
Qboid was kicked from #kspacademia by *status [You have been disconnected from the IRC server]

<bofh> I mean symphatomimetics cause pupillary dilation (like, ephedrine suffices here), which... yeah. :P
<bofh> also I have been informed I need to read АГД in the original Russian and... yeah, I really should, in all honesty.
<SnoopJeDi> bofh, yea, settling things down was my first inclination and the literature seems to be variation on that theme
<SnoopJeDi> figured I'd ask people smarter than me since I got as curious as I did
<SnoopJeDi> person's best bet for an actual solution is probably somewhere near "write a binding for [c++ tool]" or pregenerate a bunch of samples and proceed from there"
<SnoopJeDi> !wpn bofh
* Qboid gives bofh a roasted classmethod
<SnoopJeDi> you still traveling?
<bofh> I mean fair enough, there are prolly still tools.
<bofh> Also yeah, well atm I'm still at ANBO :P
<UmbralRaptor> АГД?

<UmbralRaptor> Adaptive optics are magic. https://arxiv.org/abs/1203.6708
<UmbralRaptor> "Note 3: EXOFASTv2 has been tried with GDL and does not work. Others have gotten close. If you're interested in making it work with GDL, please contact me."
<UmbralRaptor> *sob*
* UmbralRaptor apparently needs an account to download a demo of IDL.
<bofh> my sincerest condolences
<bofh> and yep, adaptive optics are magic
<bofh> relatedly, ANBO needs laser guide cows.
<UmbralRaptor> Oh, right, the cluster has IDL installed.
<UmbralRaptor> I can just ssh in and run code there. And yell at people who think this is better than anaconda.
<UmbralRaptor> (said cluster is running Ubuntu 14.something)
pthag has joined #kspacademia
<e_14159> UmbralRaptor: Your cluster has things installed? :P
<e_14159> I am shocked!
<UmbralRaptor> e_14159: well, my advisor's
<e_14159> I haven't installed anything on ours
<e_14159> (I'm very scared of software versioning issues)
* UmbralRaptor 🔪 things
<UmbralRaptor> So, uh, the test case doesn't work.
<iximeow> who wants test cases anyway
<iximeow> bofh: how plausible do you think amateur adaptive optics would be?
<UmbralRaptor> I suspect quite plausible with the right skills.
<UmbralRaptor> Lucky imaging and stacking is considerably easier, though.
<iximeow> fair
<UmbralRaptor> (Also, note that GPIE and SPHERE are on 8.2 m telescopes. >_>
<UmbralRaptor> )
<iximeow> i'll have an 8.2m any day
<iximeow> ,,,, uh,, :(
* UmbralRaptor recalls estimating that for good skies you're diffraction limited below 20 cm anyway.
* iximeow counts the number of telescopes at home that are <20cm

<UmbralRaptor> Yes, but directly measuring the mass of an M dwarf is notably rare.
<awang_> I can't open an old .psp file because of a security fix in GIMP
<kmath> <Y_ashi_n> #暑いので涼しげな画像貼る https://t.co/vnnzqbkBnn
<awang_> Not sure if I should be frustrated :(
<APlayer> How is GIMP related to security?
<APlayer> What part of GIMP needs to be secured?
<awang_> APlayer: Buffer overflow or something
<awang_> Of course whatever thing produced the file couldn't be so kind as to nul-terminate the string
<APlayer> Huh. The more you know
<awang_> It's probably safe to assume that if it's software, it's a security risk
<awang_> Somehow
<APlayer> Alright, buffer over-read is more significant than buffer overflow, TBH
<APlayer> It shouldn't expose things it shouldn't expose
<APlayer> Wait, this acronym looks wrong. So if I do
<APlayer> sphere?
<APlayer> It doesn't react. Alright, nevermind.

<APlayer> "sphere" is a common enough word to make me wonder if it makes sense for Qboid to respond with "Spectro-Polarimetric High-contrast Exoplanet REsearch instrument" whenever someone types "sphere?". But apparently it is case sensitive
<UmbralRaptor> MaDCoWS?
<Qboid> UmbralRaptor: [MaDCoWS] => Massive and Distant Clusters of WISE Survey
<awang_> Ah
<awang_> Just how much time do scientists spend coming up with catchy acronyms?
<awang_> and/or backronyms
<awang_> Or does it just come naturally?
<UmbralRaptor> Probably far too much time.
