<egg> whitequark: \o/ cats \o/
<egg> whitequark: unfortunately I don't speak russian, but with some Google translate I gather that the second is less polite than the first?
<whitequark> yes
<whitequark> it's not really translatable to english
<whitequark> but approximately, these would map to "kitty" and "this fuckery"
<egg> whitequark: yeah, that's roughly what I gathered
<egg> translating swearwords into english is hard from a french perspective too >_>
<egg> whitequark: why does the second cat have that name?
<egg> also have you managed to hate-charge a cat imaging device
<whitequark> egg: well, printer brought какую-то хуйню from the street
<whitequark> so now it's called эта хуйня
<whitequark> can't be bothered to think of a better name for a tiny scared cat with lots of skin lesions and what looks like insects
<whitequark> and covered in green oil based paint in places

<bofh> LOL
<bofh> what did it do to earn that name?
<bofh> oh, I should continue reading.
<bofh> oil-based paint? I wonder what it got into.
<whitequark> bofh: its green
<whitequark> so... someone was painting walls

<UmbralRaptor> (with a passenger area <6 ns tall)
<egg> UmbralRaptor: >_>
<egg> UmbralRaptor: any idea about whitequark's sat?
<whitequark> it's probably a US satellite active circa 1995
<UmbralRaptor> Not really. Early NOAA?
<whitequark> hmm
<UmbralRaptor> Bah, panels are wrong.
<UmbralRaptor> Also not GOES or LANDSAT
<UmbralRaptor> Incidentally, is it normal for smaller jets to pull noticeable Gs during turns?
<UmbralRaptor> I'm distantly reminded of Mars/Venus Express
<Iskierka> would depend on your sensitivity, normally would be a maximum of 30 degree turn for 41% more g
<Iskierka> ... no, that wouldn't be 41%, but I'm too lazy to check
<Iskierka> 41% would be the operational limit though as modern aircraft typically have flight director limiter at 45, and normal operation limit of 30
<bofh> whitequark: ahh. so doing the responsible thing instead of the UK thing?
<egg> bofh: want to try the linux build of Cauchy?
<whitequark> bofh: hm? no
<whitequark> you don't get it
<whitequark> the renovation is purely on the surface. put a new coat of paint. new rainwater drains.
<bofh> whitequark: JASON-1 (or JASON-3, but the latter has a much larger antenna that should be slightly visible)
<whitequark> and then they're going to demolish it anyway in half a year
<UmbralRaptor> o_O
<whitequark> bofh: ... huh
<egg> bofh: hmmm, I don't think so
<bofh> or possibly TOPEX/Poseidon
<egg> AEHF? but wrong timeframe
<whitequark> nah topex has only one panel
<whitequark> jason-1 is ... really close
<bofh> oh, good point.
<Iskierka> The UK flats have been and are being renovated, it's just that Tories voted against legislation that rented accomodation should be fit for human habitation
<Iskierka> (literal words of the legislation rejected)
<whitequark> flats? no, that's not about flats
<whitequark> they're just renovating shared spaces
<whitequark> stairways etc
<bofh> egg: like I'm fairly certain that if it's a civilian earthsat, it's ocean-targeting and not land-targeting based on where it's shown
<whitequark> hm, jason-1 doesn't quite have the same panel mount
<whitequark> but it's definitely a similar one
<Iskierka> are you not presuming they paid more attention than they probably did?
<egg> bofh: yeah, but it doesn't really look like JASON-1 to me
<whitequark> Iskierka: the russian diaspora in JP is 6,000 people. the russian language in black lagoon is of such quality that I recognize speech the first time (done by the same voice actors as JP, natch), and the handwriting combined with spelling in one scene that stays on screen for three seconds...
<whitequark> is of such quality that it could not have been done without a bilingual consultant
<whitequark> I'm certain that it's a real satellite.
<Iskierka> position of satellite may be too much detail, however
<whitequark> oh, it's pointing at a plot point
<soundnfury> !wpn egg
* Qboid gives egg a Hamiltonian
<egg> bofh: otoh it does have a bus that looks like it
<whitequark> I imagine the real satellite is going to hang somewhere near
<bofh> egg: like I'll put money on this being at least a joint project with CNES, since it looks very much like their standard buses (CALIPSO looks very similar too, but wrong timeframe)
<egg> JASON 2?
<whitequark> it might be slightly anachronistic, plus-minus five year
<egg> hm
<bofh> like for another point of reference, ASTRA 5A (Sirius 2)
<egg> bofh: I'm not sure what to make of the shape at the back of the bus (towards the observer)
<whitequark> oh, that's closer...
<egg> bofh: whitequark: so then that points to http://space.skyrocket.de/doc_sat/aeosp_spacebus-b-class.htm
<egg> (that site is nice, lists of sats by bus!)
<bofh> basically I'm going thru Thales Alenia Space launches right now, Spacebus 3000/3000B atm
<bofh> egg: ooh, thanks, did not know about it, useful!
<egg> bofh: I also just found out about it
<egg> thanks whitequark for making us find new sat nerdery sites :-p
<whitequark> hahaa
<egg> bofh: I find the lack of parabolic antennae on whitequark's image disturbing though
<bofh> egg: yeah same
<bofh> egg: but that likely just means it's not a comsat
<egg> bofh: yeah but all the sats on that bus are
<whitequark> maybe it's a similar bus?
<whitequark> i mean, look at this: http://www.imfdb.org/wiki/Black_Lagoon
<bofh> like I'd say RADARSAT-1 if it wasn't for the lack of the CSAR antenna (it shouldn't be *totally* obscured by the solar panels)
<whitequark> there are a few faithful to the reality destructive devices that weren't featured *anywhere except that anime*
<whitequark> i'm 100% sure it's a real satellite
<bofh> (oh, and the 5 panels)
<bofh> Yep, same.
<whitequark> what on earth is this even http://www.imfdb.org/wiki/China_Lake_Launcher
<whitequark> I could have sweared it doesn't exist
<egg> !wpn -add:wpn ТП-82
<Qboid> egg: Weapon added!
<egg> bofh: TIL the bus for GRACE is by Astrium http://space.skyrocket.de/doc_sat/astrium_flexbus.htm
* UmbralRaptor is surprised that the Russian is so good in Black Lagoon. The English is, uh… I needed subtitles.
<bofh> http://www.satnews.com/images_upload/768808220/54948b2293d57.png were it not for one less panel than shown, INMARSAT-2 F2 matches perfectly.
ferram4 has joined #kspacademia
<bofh> would be even the correct timeframe and orbit too
<UmbralRaptor> The parabolic antennae are metastisizing.
<egg> bofh: I guess that's more a feature of alphasat than the bus, but yeah, it's silly
<egg> !wpn UmbralRaptor
* Qboid gives UmbralRaptor a depleted variety
<UmbralRaptor> !wpn egg
* Qboid gives egg a top falconet which vaguely resembles a polyhedron

* Qboid gives bofh a characteristic 0 morphism
* egg pokes the channel with Cauchy
<whitequark> UmbralRaptor: yes, the english is actually *worse* somehow
<whitequark> both in writing and in speech
<UmbralRaptor> It's mildly troubling given that 3 of the crew are supposed to be americans. >_>
<egg> bofh: yeah the Eurostar bus seems right
<UmbralRaptor> Behold the blonde haired, blue eyed Jew! (okay, this can happen, but was still amusing)
<UmbralRaptor> On an unrelated note. This seatback has a PS/2 and a USB port
<Iskierka> USB is understandable, PS/2?
<egg> wrong number of panels again, but what do you think of ECS? http://space.skyrocket.de/doc_sdat/ecs-1.htm
<egg> also I think Qboid needs to learn some new acronyms
<egg> ECS?
<egg> !acr -add:ECS European Communication Satellite
<Qboid> egg: I added the explanation for this acronym.
<egg> !acr -add:MARECS MARitime European Communications Satellite
<Qboid> egg: I added the explanation for this acronym.
<egg> !acr -add:OTS Orbital Test Satellite
<Qboid> egg: I added the explanation for this acronym.
<kmath> <mnxmnkmnd> @whitequark @eggleroy @bofh453 what i'm getting out of this is that satellite design needs more creativity
<egg> (though tbh there are a whole lot of very distinctive sats, it's just that this one is *really* nondescript)
<egg> that's an obvious one :-p
<UmbralRaptor> Whee, pulling back to a gate for maintenance issues.
<egg> UmbralRaptor: ow
<egg> UmbralRaptor: you're on your second flight? or has your first one not taken off in 3 h

<UmbralRaptor> I'm in a 737 at DFW
<bofh> egg: I was thinking *maybe* MARECS
<egg> bofh: looks more like ECS than MARECS to me? but yeah, could be that bus

<egg> mostly had no idea what I was doing, but found out about this CAT mishap
<egg> UmbralRaptor: CAT(k).
<egg> From my BS thesis:
<egg> A remark about the name of this inequality. The term “CAT (?)-inequality” first appears in Gromov’s 1987 paper [12, Remark 2.4.C, p. 106], where the name is explained as “comparison inequality of Alexandrov–Topogonov”. Some more recent works, e.g., [18] expand this to “Cartan–Alexandrov–Topogonov” instead. The confusion may be due to the subsequent section of Gromov’s paper, the Riemann–Cartan–
<egg> Alexandrov–Topogonov theorem.
