13:26 <awang> UmbralRaptor: Nah, this is the unix find command

13:27 <awang> Finding all *.lib files and then using dumpbin to see whether they export memmove

13:27 <UmbralRaptor> ah

13:27 <awang> It outputs stuff when sitting relatively deep in a directory tree, but not when sitting in /c/

13:31 <awang> Turns out memmove is exported in vcruntime.lib

13:42 <awang> Anyone here have experience with the Eigen C++ library

16:20 <bofh> oh it was 37.8degC in Marseille according to MétéoFrance like an hour ago)

16:24 <UmbralRaptor> Fun

16:25 <bofh> I take it based on how few people have A/C that highs >35degC that many days in a row are unusual for the region?

21:39 <egg> UmbralRaptor: how do stack images without losing what is left of my sanity

21:40 <UmbralRaptor> This requires either Photoshop shenanigans or dealing with FITS files, so back up your sanity offsite and restore later?

21:41 <egg> so i have fits files already

21:42 <egg> but i'm having trouble getting SIPS to align things even when i hold its hand to point at the stars i want to align

21:42 <egg> it somehow doen't actually align the points i ask it to align?!

21:42 <egg> ytib bats

21:42 <UmbralRaptor> o_O

21:43 <egg> also it if i use its automated mode it is really good at finding hot pixels

21:43 <egg> those don't align all that well,

21:46 <egg> UmbralRaptor: help i have found some idl, where do i hide

21:47 <egg> also snek wrappers for IRAF

21:47 * UmbralRaptor quickly gives egg a snek.

21:47 <kmath> <whitequark> Help. Everything I touch becomes programming

21:51 * Qboid gives UmbralRaptor an aberrant rope-like metric

21:51 <egg> IRAF?

21:51 <Qboid> egg: [IRAF] => Image Reduction and Analysis Facility

21:51 <egg> TOPCAT?

21:51 <Qboid> egg: [TOPCAT] => Tool for OPerations on Catalogues And Tables

21:52 <iximeow> egg: tbqh KOS is about when i stopped playing ksp because it was programming and why don't i program real things

21:52 <iximeow> on the topic of space, uh, i'd love a good image stacking solution, they all seem bad

21:53 <iximeow> (i just do it by hand in paint.net, also bad)

21:53 <egg> iximeow: tbh i never touched kos because it seems like a stupid language anyway

21:53 <egg> i'm fine with programming for ksp-related things, see principia

21:53 <egg> or rather programming some sort of astronomy lib that happens to have a ksp mod growing out of it,

21:53 <iximeow> doesn't it have bindings to external languages? i thought i remember lua

21:54 <iximeow> .... apparently i replied to that tweet

21:54 <UmbralRaptor> kRPC?

21:55 <egg> yeah that's less silly

21:55 <egg> tho by the time i heard about it i was working on principia

21:55 <egg> ah also iraf doesn't eggsist for windows

21:55 <egg> welp back to beating sips with a stick i guess

21:56 <egg> (no i will not add fits image processing to principia, at least not tonight)

21:57 <UmbralRaptor> Proposed KSP mod: save screenshots as FITS.

21:58 <iximeow> .fits.txt

21:58 <UmbralRaptor> uh

21:59 <UmbralRaptor> (I mean, I think you can have a FITS that's all header?)

22:00 <egg> UmbralRaptor: i thought that was a thing?

22:00 <egg> what format are topcat tables in?

22:01 <UmbralRaptor> … it's 301 K and raining. o_O

22:01 <UmbralRaptor> egg: whatever format you want. TOPCAT supports a bunch.

22:14 <UmbralRaptor> Find hot pixels in your detector tonight!

22:26 Snoozee is now known as Majiir

22:33 <egg> okay the alignment tool is happier when it's not trying to align hot pixels from the mean of darks,

22:34 * awang_ can't seem to find Eigen's determinant() implementation

22:35 <awang_> Or at least the implementations are hidden a lot deeper than I expected

22:36 <awang_> Eigen is header-only, right?

22:36 <awang_> So why does Clang say that the definition is unavailable?

23:47 <UmbralRaptor> 545 megatons from 520 atmospheric and underwater nuclear tests in the 20th century.

23:47 <UmbralRaptor> … what's the current megatonnage of the US and RU arsenals?

23:48 <iximeow> ... i imagine much more

23:48 <iximeow> thought: 1/11th of that tonnage was one bomb

23:49 <UmbralRaptor> The really huge ones are out of service, and warhead counts are way down from the 1980s.

23:50 <iximeow> the US still has what, ~4-5k warheads? are they really below 100kt each?

23:54 <UmbralRaptor> It's complicated.

23:54 * UmbralRaptor pokes the net. https://www.armscontrol.org/factsheets/Nuclearweaponswhohaswhat

23:56 * iximeow is reminded of a little ditty by mr Lehrer

23:56 <UmbralRaptor> Well, yes.

23:59 <UmbralRaptor> Looks like 100 kilotons to 1 megaton (ignoring that the B61 can be set for lower yields)
