<tawny>
UmbralRaptor, idk if you ever got an explanation but the sun doesn't really emit gamma rays at all, while the moon's surface (idk what minerals or elements exactly) gets hit with cosmic rays and emits gamma rays as a result
<tawny>
I've seen a lot of highly misleading headlines and quotes about that exact fact
<tawny>
claiming things like "if you could see gamma rays the moon would be brighter than the sun", implying the moon gives off WAY more radiation than the sun in total but really it's not exceptional
<tawny>
I'm pretty sure basically any rocky surface with similar area in the sky would be brighter when you only consider gamma radiation

egg|zzz|egg, your integrators came up in conversation during our Astronomy on Tap event last night

egg|zzz|egg: Well, maybe if someone wrote a Mario-in-KSP mod...

SnoopJeDi: huh
<SnoopJeDi>
I mean, it was me who did it
<egg|zzz|egg>
awang: also have you tried TRAPPIST-1

Nintendo is leaking into more academia fields, and I'm not complaining

egg|zzz|egg: No, unfortunately

Haven't booted KSP in ages

<egg|zzz|egg>
bofh: this RFC makes me love the ISO/IEC JTC 1/SC 22 process
<egg|zzz|egg>
I mean the ISO process in general, NBRs can be daft but they avoid this particular flavour of nonsense
<egg|zzz|egg>
bofh: FORTRAN still doesn't have non-ASCII identifiers though, wonder what the DK NBR has been up to in that WG
<bofh>
I have no idea, honestly.
<bofh>
I'm basically unfamiliar with anything in Fortran past F95.
<egg|zzz|egg>
I'm impressed that C has had this since 99
<bofh>
Same, honestly. Would not have expected that.
<egg|zzz|egg>
(they did it rather badly because there was little guidance from Unicode then obviously)
<egg|zzz|egg>
(and this means it's badly done in modern C++ because based on it)
<egg|zzz|egg>
C# and Ada do it well within their respective constraints (that's 2002 and 2005), they'd probably be done a little bit differently with the more flexible UAX31 than with the annex of UAX15
<egg|zzz|egg>
yes the standard annex used to have an annex, which is now its own standard annex
<awang>
UmbralRaptor: o_O
<awang>
That seems insanely high
<egg|zzz|egg>
PEP 3131 goes with UAX31 pretty much directly, but screws up the choice of normalization (it's a case sensitive language so should use C), maybe Unicode didn't have an explicit recommendation at the time
<awang>
Then again, I haven't done many interplanetary burns in RO, so idk what my frame of reference is
<awang>
Actually
<awang>
Isn't TLI ~3000 m/s?
<awang>
Maybe it isn't that bad
<UmbralRaptor>
awang: red dwarfs actually hate you.
<UmbralRaptor>
3400 m/s, IIRC.
<awang>
UmbralRaptor: Wait, so are those interplanetary dv values really high or something?
<UmbralRaptor>
somewhat high.
<UmbralRaptor>
The Oberth effect greatly mitigates them.
<awang>
Right, because everything is so close in?
<awang>
How much would gravity assists help there?

Because everything is so close?

<bofh>
egg|zzz|egg: my question is why don't more people use normalization forms D/KD
<egg|zzz|egg>
hysterical raisins like literally everything?
<egg|zzz|egg>
most things tend to input NFC because precomposed characters are the ones that correspond to old encodings
<bofh>
except I'm not sure that applies, all 4 forms came out at the same time and (K)D is just (K)C *minus* a step at the end.
<egg|zzz|egg>
yes but that's irrelevant
<egg|zzz|egg>
ISO-IR-069 came out rather a long time ago
<egg|zzz|egg>
and similarly for ISO/IEC 8859-1
<egg|zzz|egg>
old character sets had precomposed characters (or rather no concept of combining marks)
<egg|zzz|egg>
those were encoded into the universal coded character set
<egg|zzz|egg>
things that input now-precomposed characters just work the same
<egg|zzz|egg>
Unicode very importantly doesn't exist in a vacuum, that's why it actually works and is full of compatibility stuff (stares at ohm symbol etc.)
pizzaoverhead has quit [Ping timeout: 194 seconds]
<bofh>
Fair enough.
<awang>
egg|zzz|egg: What happened to the ohm symbol?
<egg|zzz|egg>
awang: wait yes it is supposed to be omega
<egg|zzz|egg>
awang: it is *not* supposed to be ohm sign
<egg|zzz|egg>
the ohm sign is omega not ohm sign :D
<egg|zzz|egg>
(that's not a normalization matter, but the apostrophe is right single quotation mark, not apostrophe)
<bofh>
egg|zzz|egg: yeah I figured that's why we have the mess that is U+AD00 - U+D7A3 instead of just 3 small blocks of decomposed Jamo like what would be sensible.

Why does Japan need a code point specifically for the era name?

Can't reuse the code point for the existing character?
<egg|zzz|egg>
it's two characters squashed into a square
<awang>
Ah
<awang>
the other characters in the paper looked like a plain Chinese character to me, so I thought it might already exist
