<egg|anbo|egg> whitequark: that’s another one of those weird PDFs where the Latn text is garble-encoded somehow O_o
<egg|anbo|egg> I don’t run into them that often anymore but they remain a thing (the maths are way less reliable though)
<egg|anbo|egg> Meanwhile when I produce PDFs it says, e.g., 1. integer arithmetic is used to get a an initial quick approximation 𝑞 of ∛𝑦;

<SnoopJ> 🌟
<egg|anbo|egg> whitequark: where is that quote from
<whitequark> egg|anbo|egg: i came up with it this morning
<whitequark> after talking to a dear friend
<SnoopJ> it definitely has a ring of familiarity about it
<whitequark> it's a riff on "and yet a trace of the true self exists in the false self"
<egg|anbo|egg> aaaaah
<whitequark> except very different
<SnoopJ> guess it depends on the definition of tru—dammit ontology, shoo!
<whitequark> it's why even someone with the worst ptsd i've seen can give another person an understanding of unconditional love
<whitequark> the original template is this: https://i.imgur.com/vksTj58.jpg
<SnoopJ> very timely for me, I just started Parable of the Talents which has more than a little of the cyclical thing going on
<whitequark> and there was also, uh, moment
<whitequark> i'm not actually sure about the cyclical part
<SnoopJ> yea I guess it's not a "true" semiotic cycle, maybe there's a better way to phrase that
<SnoopJ> we chatted a bit about Earthseed while taking the dog for a walk so I guess the pump was primed
<SnoopJ> (the nonsense free association pump, that is)

<whitequark> it's less about cycles and more about connection to the world at large
<SnoopJ> mm, graphs
<mofh> whitequark: re: PDFs: qbrt.pdf uses Type 3 fonts. once you invoke those, all bets are off.
<mofh> T3 fonts are, unlike the ohter font types allowed in a PDF, not a type of font file, but a limited subset of PDF drawing operators that define *each character*.
<mofh> yes it's literally yodawg i heard you liked pdf so i put some pdf in your pdf
<whitequark> um
<mofh> but as it's not a font, there's no concept of letter mapping
<mofh> you just define a sequence of GIDs
<mofh> until i think PDF5 or PDF6 there was no requirement to provide either a /ActualText or a /ToUnicode map so there's no sane way to interpret those indices
<mofh> a lot of clients just literally just try to interpret the indexes as CIDs or CIDs+0x20, with... okay, this literally bsically never works to the point where i disabled text extraction attempts from T3 fonts in my local copy of both libpoppler & mupdf.
<whitequark> ohhhhhhhh
<mofh> like all you have is say "glyph 1", "glyph 3", "glyph 7", "glyph4" in a sequence & you need to evaluate path drawing commands then OCR the drawn path to realize that was 'a', 'r', 's', 'e'
<mofh> thankfully the one major generator of T3 fonts was metafont in dvipdf
<mofh> which mercifully seems to have stopped being used in light of, like, saner things like xetex
<egg|cell|egg> Even pdfLaTeX, right?
<egg|cell|egg> Obviously if you want Unicode sanity and reasonable encoding of the maths you need Xe(La)TeX
<mofh> yeah like if it doesn't call metafont you're good

<raptop> yes

<galois> egg|anbo|egg: I last saw Ellied in here 1 year, 8 months ago, saying: we guess it was specifically some stuff underneath the black bars in Ará Orún (there's text under there - he wrote it all so that the redaction would look realistic) that was just "wow, does qntm need a hug"

<iximeow> egg: the former owner of the NAFO instrument never changed the mount location settings from when it left the factory, so it was ~14 degrees off from where it thought it lives. this may explain the light dec drift i've been dealing with, as it's trying to compensate for polar misalignment that doesn't exist
<iximeow> he never cared about this much other than weird behaviors when power cycling the mount because the OAG papered over issues
* raptop is also commenting on how IIRC, the NAFO instrument is 432 mm
<iximeow> indeed
<egg|anbo|egg> iximeow: ah
<egg|anbo|egg> raptop: iximeow: yeah the ANBOscope is 200 mm but silly in different ways (long long focal, very flat focal plane iirc)
<egg|anbo|egg> (which I am probably not taking advantage of with smol sensor)
<iximeow> long john focal
<egg|anbo|egg> I guess I should get a bigger sensor (and maybe do shorter exposures to try to fight the atmosphere?)
