<SnoopJ> hmm
<SnoopJ> !8 is that an extant genre of SF literature?
<galois> SnoopJ: no
<raptop> carcinization stories?
<SnoopJ> I was thinking more asteroid-summoning
<SnoopJ> certainly Great Old Ones hanging around as planetary detritus is a thing? at least I think I've heard at least one story that way
<raptop> Oh, that's more of a world-building thing than a genre
<raptop> pun not intended
<SnoopJ> I guess maybe I'm thinking 'hard' space + eldritch horror
<raptop> ah
<SnoopJ> ...I guess Peter Watts and Liu Cixin count depending on what's "eldritch"
<SnoopJ> and maybe tucked away somewhere in the Laundry universe somewhere away from the narrative spotlight
<raptop> Probably some cannons for the SCP Foundation, too
<raptop> While not actually what you mean, I'm reminded of Trinity Blood (where there's a bunch of what's basically magic, but everyone understands it to be fancy technology, and treat it as such)
<SnoopJ> ooh

<iximeow> U=8.6 though, which is better than.... 10.4
<raptop> I guess that helps

<SnoopJ> iximeow, I made a cheeky remark on a thread about the typosquatting thing about how you can't patch human beings and someone replied "well actually if you could point at a repository..."
<iximeow> lol
<iximeow> i think this is pretty different in that precedence rules of package managers aren't super obvious
<iximeow> and not being able to explicitly host your own repositories for most of them is a huuuuuge mistake
<SnoopJ> I think their point was like, string name resolution makes the fault possible in the first place
<SnoopJ> and getting rid of that technically does "solve" the problem
<SnoopJ> but like glhf getting people to give up the convenience of naming a thing
<SnoopJ> at least pip's support for alternative indexes like devpi does make Python tooling look *slightly* less terrible here
<SnoopJ> and poetry/pipenv are capable of locking the hash of the actual content, although tbh this doesn't really address the problem. not really a fix if you `poetry add wrongpkg`
<raptop> Vaccines are basically patching humans, right?
<raptop> Anyway, it's always amusing how many "video" conferences amount to conference calls plus the occasional slide
<SnoopJ> interesting question
<SnoopJ> feel like that's updating the allow/deny lists but...I guess that's a patch?
<iximeow> SnoopJ: but getting rid of string identifiers introduces a whole new category of problems ("use this package hash: ...." is somewhat harder to look at than the string identifier)
<iximeow> and so long as your identifiers resolve to something with some data, solutions i can imagine (look at your dependency tree to make sure it's things you expect, and not what you don't) apply in both ways
<SnoopJ> exactly
<SnoopJ> so I feel pretty confident in saying this vuln is mostly in meat
<SnoopJ> which is not to excuse package management from its role
<SnoopJ> !wpn iximeow
* galois gives iximeow an edgy tardigrade
<iximeow> oh this particular one where sometimes they'll just pick a different registry, which might have wildly different content
<iximeow> that's uh, dangerous tooling
<raptop> But like, shouldn't local reps take priority by default (and there's a clear way to set the priority)?
* raptop pets the tardigrade
<iximeow> "local" might be "our registry inside the corp vpn"
<iximeow> so maybe you say "the language default is the lowest priority" but still
<raptop> My understanding is that there's no human involvement on the defender side of that attack, so why talk about it like people are the vulnerability?
<SnoopJ> I guess I'm talking about not-quite-this vuln
<SnoopJ> in the case of pip you should be pointing explicitly at the inside index anyway
<SnoopJ> the higher version number thing is just...bad
* SnoopJ usually pins exact versions anyway
<SnoopJ> I dunno, I guess it's surprising people are using --extra-index-url for internal deps at all but maybe they're not separating internal/external stuff and just smoosh it all together
<egg|anbo|egg_> iximeow: current telescope pointing: M42
<raptop> Obviously ANBO should provide additional data on the asteroid >_>
<iximeow> \o/
<iximeow> can ANBO see to 20th magnitude?
<egg|anbo|egg_> hm
<egg|anbo|egg_> 200 mm aperture, but haha long focal
<egg|anbo|egg_> bit of wind too, so not going to like long eggsposures
<egg|anbo|egg_> (the wind is what makes it possible to observe in optical, otherwise it’s all clouded up here)
<egg|anbo|egg_> here it is merely freezing
<raptop> hrm
* raptop sort of wishes I had clear discressionary time on the GMU telescope
<raptop> astronomers titling things: https://arxiv.org/abs/2102.04772
<galois> title: [2102.04772] The curse of clouds
<egg|anbo|egg_> iximeow: where is your object anyway
<egg|anbo|egg> I wonder if I should set up a way to control telescope pointing without going out in the cold
<egg|anbo|egg> I am remote-desktoping to my laptop to image because it is too cold down there, but I cannot adjust the pointing from here
<iximeow> it's good to be able to remotely point
<iximeow> 5h34m00.8s/+21h43m55.5s, last i saw
<iximeow> it should still be somewherer close, maybe an arcmin of motion per day
<iximeow> (a bit downward of M1)
<egg|anbo|egg_> uh declination in hours is evil
<egg|anbo|egg> M1 would be up
<raptop> RA and Dec minutes being different is evil
<egg|anbo|egg> iximeow: but bear in mind ANBOscope FoV of 14′,13 by 9′,55
<egg|anbo|egg> i.e., M1 fills the frame
<egg|anbo|egg> or I can go widefield with the finder but then I have 80 mm aperture, not 200
<raptop> ...I'm just going to call our campus telescope GMUO
<raptop> Anyway, current GMUO conditions: snow
<egg|anbo|egg_> I recommend loooong wavelengths
<egg|anbo|egg_> iximeow: do you have M42 pics in your tweetes ? I am looking for one but not finding
<egg|anbo|egg_> ah yes eggstremely widefield even https://twitter.com/iximeow/status/1191259770906300418/photo/1
<raptop> so many nebulae
<egg|anbo|egg_> for some reason I did not find that one while searching for orion ? ? ?
<iximeow> egg|anbo|egg_: wow long focal
<egg|anbo|egg_> haha long focal
<iximeow> yeah twitter's search index for my tweets is broken because i did a private/public flip
<egg|anbo|egg_> VC200L
<raptop> long long focal?
<egg|anbo|egg_> f/9
<iximeow> not a fantastic image, i need to figure out how to mosaic well
<iximeow> (which is why it's not on twitter)
<egg|anbo|egg_> iximeow: if you want I can send you some high-res shots of the bright middle bit soon :-p
<iximeow> :D
<egg|anbo|egg_> I might try doing some widefield images in the 80 mm finder
<egg|anbo|egg_> it’s f/3.75 so goes pretty wide
<egg|anbo|egg_> iximeow: also do you have some M101
<egg|anbo|egg_> or some M57
<iximeow> if you want 4gb of fits, yes m101
<iximeow> no m57 yet
<egg|anbo|egg_> lol
<egg|anbo|egg_> I have this for M57, 119 30 s exposures back in June https://photos.app.goo.gl/eTNKdE4mXnC2o4G46
<galois> title: Shared album - Robin Leroy - Google Photos
<iximeow> nice!
<egg|anbo|egg_> and M101 from March https://photos.app.goo.gl/Ns9owJ9VRNmKmcqi9
<galois> title: Observations du JD2458935 & images de calibration - Google Photos
<egg|anbo|egg_> OK just did 60 30 s exposures of the brightest part of M 42, that should hopefully be enough given how shiny it is
<egg|anbo|egg_> will try switching to widefield without freezing to death, wish me luck
<iximeow> good luck
<iximeow> oh right and current location of The Asteroid
<iximeow> should be 5h34m03.56s/+21d42m54.95s
<egg|anbo|egg_> iximeow: probably not going to try, with my field and the lack of goto that would require a looooot of hand navigation in the coooold
<iximeow> oh lack of goto
<iximeow> oof
<egg|anbo|egg_> here we go for 30 min of widefield orion
<iximeow> i'd like to piggyback a like. f/2.8 on the big scope
<iximeow> i need to figure out how to focus it though
<egg|anbo|egg_> my widefield is 1°24′,79×57′,29
<egg|anbo|egg_> 80 mm aperture, and a refractor rather than a kitty
<egg|anbo|egg_> (kitty with a spider)
<raptop> Obviously a kitty is the correct name for a smol cat (say, those 90 mm MCTs)
<egg|anbo|egg_> OK 200 mm is probably starting to get into cat range
<egg|anbo|egg_> a C14 would be chonk
* raptop considers those two 16" Meades that we have just lying around in the observatory
<egg|anbo|egg_> iximeow: what is your FoV & aperture on your imaging setup
<iximeow> 432mm and i THINK 41' by 27'15" but i really need to get proper notes together
<egg|anbo|egg_> iximeow: a thing just crossed the frame (sat? meteor? There seems to be a vague light curve but that might also be that I am not looking at it through a flat)
<egg|anbo|egg_> (note that since I switched to widefield there will be no flat on the high-res pictures)
<egg|anbo|egg_> (my flats don’t appear to change much in practice anyway, just don’t do photometry on my narrow-field M 42 pics I guess)
<egg|anbo|egg_> > here we go for 30 min of widefield orion
<egg|anbo|egg_> augh they are saturated, stupid egg
<SnoopJ> pls no abuse egg
<SnoopJ> !wpn egg|anbo|egg_
* galois gives egg|anbo|egg_ a kobold leek
<SnoopJ> nutritious
<egg|anbo|egg_> FFS even the narrow-field ones are saturating :’(
* egg|anbo|egg_ stabs things
* iximeow reduces exposure
<egg|anbo|egg_> iximeow: alternatively, gain
<egg|anbo|egg_> I was at max gain, because that is what I do for deep sky stuff that is not full of bright stars
<egg|anbo|egg_> or bright itself
<iximeow> oh max gain will do it
<egg|anbo|egg_> OK, saturating at highest dynamic range too :-p
<egg|anbo|egg_> bright nebula is bright
<iximeow> i have become very skeptical of "high gain", for the camera i'm using anything beyond 1.0e/adu is just.. stretching sensor observations
<iximeow> i can do that later AND keep dynamic range
* iximeow has been very offended since looking at a histogram and seeing one vertical bar every 7 counts, because "max gain" is just "multiply counts by 7"
<egg|anbo|egg_> iximeow: OK but, uh, highest at 1 s still saturates on the stars
<iximeow> .... what's your camera again?
<egg|anbo|egg_> ZWO Color Astro Camera ASI178MC-cool
<iximeow> oh yes, smol pixel
<egg|anbo|egg> iximeow: ?
<egg|anbo|egg> iximeow: anyway, two single 30 s exposures, binned 2 by 2, debayered, no further treatment, one narrowfield one widefield, wdyt https://photos.app.goo.gl/zVLwwg4HC6GciBJt6
<galois> title: M 42 - Google Photos
<iximeow> \o/
<iximeow> your red and blue are backwards
<egg|anbo|egg_> uh
<egg|anbo|egg_> hm
<egg|anbo|egg_> right i want x odd, not y odd
<raptop> huh, looks almost like a WISE image
<egg|anbo|egg> iximeow: a clearer look at what saturates on the widefield pic https://photos.app.goo.gl/2d5NJsxA5vjiSvm59
<galois> title: Shared album - Robin Leroy - Google Photos
<egg|anbo|egg> (obvious answer, learn how to mosaic and mosaic in the narrowfield stack :D
<egg|anbo|egg> uh what happened I am not seeing anything when exposing
* egg|anbo|egg goes downstairs
<egg|anbo|egg_> (meridian flip)
<egg|anbo|egg> uuuuh now if i set it to lowest read nois it is no longer saturating on the nebula
<egg|anbo|egg> is it even picking up my setting changes
<iximeow> weird
<egg|anbo|egg> it is clearly a lot darker/noisier so I am going to guess it is still hdr
<egg|anbo|egg> yeah if I restart sips it is now saturating again
<egg|anbo|egg> great, gain changes require a restart
<iximeow> restart of... the camera?
<egg|anbo|egg> of the capture/processing software
<iximeow> hm
<iximeow> unfortunate
<egg|anbo|egg> also the gain is seemingly not part of the metadata
<egg|anbo|egg> this seems suboptimal
<egg|anbo|egg_> iximeow: anyway, onwards with 30 min of hdr widefield imaging
<egg|anbo|egg_> iximeow: how can I use the saturating images
<egg|anbo|egg_> (or rather, how can I combine the things)
<egg|anbo|egg_> (how is mosaic formed)
<iximeow> i only have bad processes to speak of
<iximeow> i mosaic in paint.net
<iximeow> deepskystacker can mosaic, and in osc + one evening it's ok, but if your data needs any normalization (different moon brightnesses etc), ime it's a bad time
<egg|anbo|egg_> I used my scope to take a picture of some fireworks once https://photos.app.goo.gl/cNWDFD1BDB9pZvU98
<galois> title: Shared album - Robin Leroy - Google Photos
<iximeow> oooh
<egg|anbo|egg_> probably ~5 km away
<egg|anbo|egg_> don’t remember which scope I used, probably the big one ?
<egg|anbo|egg_> that definitely is a narrow field given the size of the telephone pole of sorts at this distance
<egg|anbo|egg_> !wpn iximeow
* galois gives iximeow a Wheeler jump
<egg|anbo|egg_> !wpn raptop
* galois gives raptop a PC-compatible MX firefly
<egg|anbo|egg_> iximeow: also should I reimage at a lower gain in narrowfield or is the narrowfield image I linked good enough (the stars are saturating but not the nebula)

<iximeow> hmm what would be good
<iximeow> egg: m81?
<egg|anbo|egg_> that would work but also the star hopping sounds painful by -5 °C
<iximeow> oof
<egg|anbo|egg_> maybe I should take flats on the finder, M42 has stuff to the edge and this thing is supposed to be a finder rather than an imager so it may be worth it for once
<egg|anbo|egg_> (on the big scope the flats find a bit of dust but that’s generally not visible on the image anyway, and the field is well lit otherwise)
