UmbralRaptor: yeah same, researchgate's read counter is BS
<UmbralRaptor>
stabbity
<UmbralRaptor>
Yay, transit cats.
<egg|zzz|egg>
UmbralRaptor: I want to see light curves from transiting cats
<UmbralRaptor>
egg|zzz|egg: probably weird buckets. Occulting cats would better reveal the shape.
<egg|zzz|egg>
UmbralRaptor: would the cats jump into the buckets
<UmbralRaptor>
uh
<UmbralRaptor>
If you shine a laser guidestar in them.
<egg|zzz|egg>
UmbralRaptor: why would occultation work better to deduce shape?
* egg|zzz|egg
is confused by bofh's cheese tweet
<UmbralRaptor>
egg|zzz|egg: I'd eggspect higher SNR and more precise timings.
<egg|zzz|egg>
aha
<egg|zzz|egg>
UmbralRaptor: are there occultation observations in the TRAPPIST-1 system? I saw only transits
<UmbralRaptor>
Also, typical occultation detection effectively has some angular resolution.
<UmbralRaptor>
Because of scopes multiple km apart.
<egg|zzz|egg>
bofh: amusingly, not only does the shitty twitter langdet detect it's romanian, bing actually tries to translate it
<UmbralRaptor>
egg|zzz|egg: well, no.
<UmbralRaptor>
But presumably cats are easily moved.
<egg|zzz|egg>
UmbralRaptor: ah, is it insufficiently edge-on to have both?
<UmbralRaptor>
egg|zzz|egg: my working assumption was grounded in cats, rather than TRAPPIST-1, so they could be treated like asteroids in our solar system. No exoplanet is able to fully eclipse its host star AFAIK.
<egg|zzz|egg>
Ellied: did diodebot get a new profile pic?
<armed_troop>
egg|zzz|egg: I think we have that one already
<egg|zzz|egg>
UmbralRaptor: no but I'm just confused as to why they have transits and not occultations for the TRAPPIST-1 planets
<bofh>
egg|zzz|egg: ROFL the translation literally just rearranges some words.
<egg|zzz|egg>
yeah
<egg|zzz|egg>
bofh: tbh the tweet still confuses me after rearrangement

egg|zzz|egg: AIUI: transit: obscuring body has smaller angular size than the star/incompletely covers it. Occultation: the obscuring body is larger/completely blocks the star.
<UmbralRaptor>
The Moon is weird.
<egg|zzz|egg>
UmbralRaptor: the star occults the planet tho
<egg|zzz|egg>
I can't seem to see that modeled in rodluger's planetplanet
<UmbralRaptor>
maybe
<UmbralRaptor>
Aaaaaa!
<UmbralRaptor>
If nothing else, earth's orbit. Yes.
<egg|zzz|egg>
UmbralRaptor: I mean TRAPPIST-1 is comparatively smol, but if you have e.g. Mars and Earth, 8 min vs. 12 min might get noticeable
<egg|zzz|egg>
UmbralRaptor: (probably not critical for star transits, since those are comparatively long, but for planet-planet transits this seems like a critical issue)

I suppose. Suddenly things like stellar abberation sound like they'd matter.
<egg|zzz|egg>
UmbralRaptor: in a sense, but that would apply to the whole system at once, right?
<UmbralRaptor>
Well, around the transits and occultations, the planets are moving tangentially to the star (and each other!) at a few km/s to a few 10s of km/s. Hopefully it's always the same relative alignment?
<egg|zzz|egg>
UmbralRaptor: yeah I think we're talking about equivalent things really
<egg|zzz|egg>
basically, the planets move fast and are far away from the star so delay is going to matter...
<bofh>
(actually the PDF I got is even smaller somehow???)

oh wow I still have that lɒl substitution in my IRC client from that time when majiir had made an ian2 kickbot :-p
<egg|zzz|egg>
bofh: my printer just barfed a blank page
<egg|zzz|egg>
I'm pretty sure the figures are cursed
<egg|zzz|egg>
I can print pages 1 through 4
<bofh>
what the hell does it do to the figures?
<egg|zzz|egg>
bofh: is it weird for you too or is my printer cursed

ferram4_ has quit [Read error: -0x1: UNKNOWN ERROR CODE (0001)]
<bofh>
so I just ran it thru pdftoppm and that gave me 6.1MB raw RGB PPMs for each page, as it fucking should. let's see what the diagrams look like in the PDF.
icefire has quit [Read error: Connection reset by peer]
<egg|zzz|egg>
the plots reminded me of the unrasterized retrobop plots
<egg|zzz|egg>
there's a reason why I *NEVER* displayed those unrasterized
<egg|zzz|egg>
(it hung mathematica :-p)
<bofh>
I am adding this to my collection of pdfs to use for testing pdf renderers, it's actually pretty nasty and saves/restores graphic state a *ton*
<egg|zzz|egg>
bofh: :D
<egg|zzz|egg>
bofh: okay but how do I print it tho :-p
<egg|zzz|egg>
[unprintable] paper
<bofh>
egg|zzz|egg: you rasterize it using pdftoppm from xpdf/poppler and send the rasterized ppm/png files to the printer :P
<egg|zzz|egg>
I'm on windows
<bofh>
I have no clue how to rasterize PDF to file on there w/o external applications (I think maybe the standard reader lets you Save As a page as png or something?)
<egg|zzz|egg>
bofh: there's xps document writer
<egg|zzz|egg>
it produces an xps that can't be read :D
<egg|zzz|egg>
bofh: maybe I could try printing it from adobe reader rather than chrome's pdf renderer though, the latter is occasionally confused
<Ellied>
egg|zzz|egg: yes, I finally got around to taking diodebot out of Halloween mode
<egg|zzz|egg>
bofh: okay adobe takes a while but actually prints it all correctly
<egg|zzz|egg>
bofh: chrome gets creative and produces incomplete prints as well as taking bloody ages
<egg|zzz|egg>
bofh: I only wasted 8 sheets of paper to produce one correct (4-sheet) print so it's all good :-p
<egg|zzz|egg>
(hopefully the printer queue is actually empty)
* egg|zzz|egg
stares at the printer queue
<egg|zzz|egg>
oh no
<bofh>
oh?
<egg|zzz|egg>
bofh: I had launched another print but I caught it in time :-p
<bofh>
is this like the time I accidentally sent a very large (~12MB) jpg to a printer directly assuming it could print it, and it decided to interpret it as uh
<bofh>
plaintext
<egg|zzz|egg>
(there's a lot of time to cancel it since it was busy lobbing hundreds of megs around :-p)
<egg|zzz|egg>
bofh: :D :D :D
<egg|zzz|egg>
bofh: how fast was the printer in pages per minute
<egg|zzz|egg>
did you keep the prints :-p
<bofh>
it was a university printer that I had worked around the payment system so I didn't really care that it managed to spit out about 300 pages of moji (about a third of them were blank, presumably it lacked the charset for those) before I could mash the "Cancel Job" button in time.
<egg|zzz|egg>
WHY IS THE PRINTER DOING THINGS AGAIN
<Ellied>
I once printed a dictionary of interesting words on a high-precision printer. MS Word told me that my formatting in four columns per page brought the the double-sided page count to 12, but the printer then put out 42 pages.
<egg|zzz|egg>
bofh: oh good the printer jammed so it didn't actually print anything
<egg|zzz|egg>
now to see whether I can clear the queue printer-side
<Ellied>
oh, it was also in 1pt font, that was why the high-precision thing was important
<bofh>
egg|zzz|egg: google says 55ppm, which is about correct

Let's see if I understand the Intel bug: every chip in the past 20 years is vulnerable, most likely so are some AMD ones, and if I'm doing CPU heavy tasks like browsing Twitter, I'll see a noticeable slowdown once the patch arrives?
<UmbralRaptor>
Also, there's no patch for OSX?
