I was thinking of IR59
<bofh>
which may or may not be visible from where you are
<egg>
oh yes the earth is not actually flat
<egg>
damn it
<egg>
bofh: yeah it's well underground until sunrise
<egg>
yeah, for sats you can't assume that the earth is a point >_>
<egg>
bofh: yeah that one next flares next night for me, peaking at 4.92
<bofh>
it's peaking at -8.2 for a friend, peaking at I think -1.7 for me
<egg>
-8.2 is impressive
<egg>
also magnitudes are silly (poke UmbralRaptor)

Commit date at the start is 2017-03-28, but built date is 2017-03-25?
<Norgg>
Are those the wrong way round?
<egg>
Norgg: tag has 2017-03-28 in the name
Thomas|AWAY is now known as Thomas
<egg>
commit date is 2017-03-25
<Norgg>
Ah, k.
<egg>
that's reported as "built date" because old string :-p
<egg>
Norgg: tag was postdated to the new moon
<egg>
built a couple of days before, released a few hours before
<egg>
also might lead to moments of *staring at graphs in confusion while rocket explosion is evident outside*
<egg>
Norgg: that would be a bit too spammy for IRC though
<UmbralRaptor>
That sounds impressively realistic.
<Norgg>
egg: You'd just grab the interesting bits?
<egg>
possibly
<egg>
Norgg: will have to learn some snek, since I'll be working in youtube which is full of that, so might do that :-p
<Norgg>
Twitch Plays KSP
<egg>
UmbralRaptor: yeah but what about the rocket design
<egg>
that sounds impractical in a terminal
<Norgg>
Ohhh, following your pa to el goog? :D
<egg>
yeah
<UmbralRaptor>
hrm
* egg
hopes that he'll get egg as a username >_>
<UmbralRaptor>
+egg
<egg>
nah, not Google+, just the actual username (email address @google.com, and used everywhere internally, turned into links etc.)
<egg>
e.g. that's what you put in the TODOs
<egg>
UmbralRaptor: for the rocket design you could have graphs/terminal stuff for analysis (after all the FAR UI isn't too far from that), but the actual building of the rocket?
<egg>
...you'd need a rocket hardware description language?
<UmbralRaptor>
Something to read part files and write craft files.
<UmbralRaptor>
RHDL… am I going to end up running KSP on an FGPA?
<egg>
UmbralRaptor: ... a language where you describe stage interfaces?
<egg>
and engine plumbing
<UmbralRaptor>
And aerodynamic surfaces.
<egg>
UmbralRaptor: so a mix of a HDL and solvespace....

although JFETs being JFETs I'm sure they don't like much current.
<GreeningGalaxy>
I've used that circuit before lots, but never heard of it consolidated into one part

<technicalfool>
isk - I think that's what Zener diodes do?
<GreeningGalaxy>
wow, that thing's expensive too
<technicalfool>
They have a designed breakdown voltage in the reverse direction.
<technicalfool>
you can use them for inefficient power regulation - any overvoltage gets dumped to ground via a whatever-volt zener.
<GreeningGalaxy>
Good for clamping sensitive stuff. I've used them to protect Raspberry Pi GPIOs.
<GreeningGalaxy>
I've also heard of Zener diodes whose reverse breakdown voltage is actually lower than the forward barrier voltage, so they conduct better backwards than forwards.
<egg>
O_o
<GreeningGalaxy>
there are also ones with negative resistance, so (to some extent) the more voltage you put across them, the less current flows.
<Iskierka>
... would that make a constant-power diode?
<egg>
Majiir: have you looked into integration again?
<Majiir>
I have not
<egg>
Majiir: the sea of paper has gotten deeper
<egg>
Majiir: I was wondering about trying to have a principia/kopernicus config for TRAPPIST-1, might be fun to play there
<egg>
but the only thing you can find is mean elements for that system
<egg>
so if I want to feed it to principia I need a proper initial state, which I need to fit to the Spitzer observation data
regex has quit [Remote host closed the connection]
<egg>
basically I need to replicate the TTV results of that Nature paper
<egg>
that will have to involve writing a minimzer because we don't have one
<egg>
won't do that just yet, but certainly something I want to look into
<egg>
!acr -add:TTV Transit Timing Variation

egg: I added the explanation for this acronym.
* UmbralRaptor
listens to another group talk about how only one person has the [spectrum fitting] code, and how they'll send out the latest version later this week.

UmbralRaptor: ... should I add spectrum fitting code to principia
<egg>
it doesn't seem too far off the scope creep
<UmbralRaptor>
egg, whitequark: I've only heard it called inside [front] cover
<egg>
UmbralRaptor: ah but that doesn't cover the first page too does it
<UmbralRaptor>
egg: version Maxwell
<egg>
UmbralRaptor: I don't think Maxwell counts?
<egg>
we do mathematicians, not physicists
<egg>
UmbralRaptor: version Fourier should be a few years off
<UmbralRaptor>
egg: well, sort of. If you don't have to turn a page, it counts.
<egg>
huh
<egg>
though those may be rather technical bookbinding terms tbh
<egg>
much like I didn't know about the white and colour guards
<egg>
(those sounds like weird elite regiments somehow)
<egg|laptop|egg>
ferram4: oooh the nyancat is back
<UmbralRaptor>
color guard most definitely sounds military.
<egg|laptop|egg>
yeah, and if you have the two then they're probably different regiments with undecipherable traditions
<egg|laptop|egg>
UmbralRaptor: given the colour, maybe the white guard is the one that surrenders and does not die >_>
<egg>
so Vessel has a function GetVessel() that returns this
<egg>
but this actually makes sense
<egg>
it's from ITargetable, Celestial returns null, and docking ports return their vessel
tfafk has quit [Ping timeout: 180 seconds]
<UmbralRaptor>
well, color guard being the people who guard/change/carry the flag(s)
<UmbralRaptor>
returns "this"?
<egg>
UmbralRaptor: this, the argument that's before the full stop in languages that do OO with classes that contain members
<egg>
(C++, C#, java, ...)
<egg>
UmbralRaptor: the call syntax is e.g. vessel.GetVessel(), and in GetVessel, which is in Vessel, the argument of type Vessel is called this
<egg>
this sentence may have too many vessels
<UmbralRaptor>
for vessel in vessel:
<UmbralRaptor>
\t vessel(vessel, vessel, vessel)
<egg>
UmbralRaptor: yeah, colour guard in french doesn't have this aspect quite as much, since the bookbinding thing is the garde de couleur (the guard of colour if you will), and the flag-guarding people are the garde au drapeau (guard to the flag); les couleurs means the colours in the flag sense, but it's not used for the guard, and note that it's plural where the endpaper is singular
