And yes, MOO is the catalog naming scheme.
<Bornholio>
here i am floating pointlessly thinking of mooing eggs
<awang>
Wonder how much time it took for them to come up with those names
<UmbralRaptor>
Bornholio: :D
<UmbralRaptor>
awang: apparently a grad student just suggested it one night.
<Bornholio>
https://i.imgur.com/AGqGSY1.jpg nother silly pic, this swivel i designed for safety factor 3 load pick of 120 tons (so is is ok to life 360tons, made four of them
<ProjectThoth>
There's a "cow jumped over the Moon" joke in here.

<ProjectThoth>
Bornholio: Cool shit!
<awang>
UmbralRaptor: That grad student needs a raise
<Bornholio>
made in virginia so i didn't get to fondle them
<Bornholio>
umbral is there a readable link elsewhere?
<awang>
Bornholio: That's the same pic
<UmbralRaptor>
? ArXiv has PDF links.
<Bornholio>
yes just noticed .doh
<UmbralRaptor>
awang: well, yes. Grad student and all that…

setting thrust or isp causes a very hard CTD
<awang>
Does this.thrust call the thrust getter?
<awang>
Recursive overflow?
<taniwha>
lamont: it might be stack overflow (infinite recursion)
<lamont>
yeah possibly
<taniwha>
set in one property calling set in the other which calls set in the first
<lamont>
oh i bet it is
<taniwha>
same could happen with get, too
<awang>
Shouldn't that still cause an exception?
<awang>
Not a hard crash?
<taniwha>
awang: no, stack overflow is a segfault (linux) or GPF (windows)
<taniwha>
very hard crash
<awang>
Not in C# though?
<lamont>
ah i see it, you have to have a separate variable to save to
<taniwha>
yes in C#
<awang>
Going off of Java experience though
<awang>
Java you get a StackOverflowError, not a hard crash
<awang>
C++ I can understand a segfault
<lamont>
i was reading some stackoverflow code on what { get; set; } expanded to a little too quickly
<taniwha>
more recent runtimes might catch it, but unity's runtime comes from before the big bang
<lamont>
and i’m using mono on mac
<awang>
Big bang?
<lamont>
ironically enough my poor reading of stackoverflow code led to a stackoverflow...
<taniwha>
can you think of anything (other than unity's mono) older? :)
<awang>
Somewhat surprised it hasn't always been caught, given C#'s inspiration from Java
<awang>
idk, I'm not nearly as familiar with C# as I am with Java
<taniwha>
might be mono-specific
<awang>
And I'm not that familiar with Java
<lamont>
i used to have to manage a pile of servers that were runing crappy java 1.4.1 code
<awang>
Ouch
<awang>
How long did you have to suffer with that?
<lamont>
and java 6 was fairly mature at that point
<ProjectThoth>
!tell ferram4 Yeah, I'm still on the interstage thing... just wondering if you think a monolithic interstage would handle the heat better (with blowout ports or something to partially restore aerodynamics for the flyback cruise).
<Qboid>
ProjectThoth: I'll redirect this as soon as they are around.
<lamont>
several years
<ProjectThoth>
lamont: Holy ouch.
<lamont>
just keep rubbing more flags on the JVM and eventually the garbage collector behaves
<awang>
They didn't update, even with Java's legendary backwards compatibility?
<awang>
Erasure was for codebases like that
<awang>
Ah, yes, GC tuning
<awang>
Black art that I'm glad to never have dealt with
<awang>
Yet
<lamont>
it looks like it got a lot better in 7 + 8
<awang>
8 especially
<awang>
Introduced the invokedynamic instruction, which opens the door to lots of magic
<awang>
Or so I heard
<lamont>
7 introduced the garbage-first collector
<awang>
Just waiting for Project Valhalla to drop
<awang>
True value types, finally
<lamont>
G1 sounded like it was going to be a big deal
<awang>
I think Java 9 deprecated the CMS collector?
<awang>
Yeah, I remember hearing a lot about it
<lamont>
but all the stuttering in mono caused by collections is very “oh yeah, i bet i know more or less what is going on there…”
<awang>
I haven't dealt with programs large enough for it to matter though
<lamont>
the CMS collector in java 6 was dope for us
<awang>
Isn't that partially because Unity's mono is still on Boehm GC?
<lamont>
all 1.4 had was generation stop-the-world
<lamont>
and i think the tenured generation was single-threaded even
<awang>
At least it was generational
<lamont>
true
<awang>
Still, ouch
<lamont>
we had machines with 20G heaps — back in 2009-ish? where the java devs slurped up everything into heap objects so it would be super speedy
<lamont>
major collections took many seconds — and we were a streaming media service
<awang>
That sounds... unfortunate
<awang>
How frequently did major collections happen?
<awang>
And how'd you deal with it?
<lamont>
java 6 + CMS helped a lot, plus convincing the devs that the file system buffer cache was smarter than they were
<awang>
That must have been a fun conversation
<lamont>
so they just mmap’d their data and read it out of a buffer and let the file system handle caching the fat part of the distribution of their data, and allow a little bit of I/O for the tail
<lamont>
well they were desperate to dig themselves out

wow, so when sending rescue vehicles, I guess it's a good idea to make sure that they actually HAVE the delta-V to accomplish the rescue so you don't have to send ANOTHER craft to rescue the first two...
