SnoopJeDi: I mean gcc 3.x should still be mostly fine if you're not compiling C++
<SnoopJeDi>
I am, but even then, these devs are insane
<SnoopJeDi>
I got frustrated with the linking against the older version I've been using, ended up converting a test simulation over to a newer (but not most recent) version, and snagged on a parallelism flaw
<SnoopJeDi>
if you load RF field data, *every* MPI process tries to read all of the data :|
<SnoopJeDi>
such that if you launch with NNODES > # of files, you will probably gridlock
icefire has quit [Quit: Gone]
<SnoopJeDi>
ooh, I was wrong, it's not a problem with the file per-se, just a stupid assumption about dividing the work up on the file (which...seems kinda pointless for loading data?)
<SnoopJeDi>
I guess it's not implausible that people would read GBs worth of field data, though.

bofh^28: how is the commutative algebra
<bofh^28>
egg|work|egg: holy shit I think I *might* have a potential research project. so many details need to be worked out (incl. timing, neither of us have spare time really), but I somehow managed to impress jcf with random ideas I had (some years old), some of which he wants to look into himself as of very recently. o_O
<bofh^28>

bofh^28, egg|work|egg suppose I was given the task of producing illuminations for some Gutenberg press-printed pages. Any ideas what would be fun to include in the margins? The only thing that's occurred to me so far is some sort of fractal and a Penrose tiling
<SnoopJeDi>
(Renn Fest was fun)
<bofh^28>
hm. my initial thought ineggsplicably was a drawing of Renard the Fox, not sure why.
<SnoopJeDi>
I will probably chuck some Jacquard loom stuff on there, because the weaving area was fun and I got to gush to my friends about them
<bofh^28>
yes those things are *great*
<SnoopJeDi>
not that they had any, but the lady who talked to us about their looms turned out to be a retired computer tech
<SnoopJeDi>
which was the perfect bow on top of my earlier "ohmygosh looms are so cool because they're basically computers"
<SnoopJeDi>
bofh^28, in my post-faire reading surge I found a video of some project in India that's digitizing the cards using computer vision!

<kosamari> Yey quick sort scarf is done! I always wanted to mix 2 of my favorites - datavis & knit! Image generated by d3.js 💕 http://t.co/YR1ggkDHKu

<SnoopJeDi>
bofh^28, so I'd never thought about how Jacquard cards are digitized
<SnoopJeDi>
and one of the videos I stumbled into had this REALLY FASCINATING mechanized machine for it
<SnoopJeDi>
pedal-operated advance, fingers operating an input a bit like a flute
<SnoopJeDi>
one advance punches holes according to operator input, advances the card, and rolls a drum (IIRC) that advances the "window" onto a drawn gridded pattern

<UmbralRaptop>
Obviously we're running the simulation out of compute
<SnoopJeDi>
floating point precision error strikes again
<BPlayer>
It feels as a sign of disrespect, and using other cases where it happened similarly is a weak argument
<B787_300>
BPlayer: i mean i would be okay with them having to move it if it was on a grave site or something physical. but the native hawaiians are saying all of the mountain is sacred
<B787_300>
and there is no other good site for it
<B787_300>
Chile already is getting the ELT and it makes no sense for another super large scope to be there
<B787_300>
there is no site nearly as good on CONUS
<BPlayer>
Hypothetical situation: Imagine someone building an observatory in the middle of the Grand Canyon (not discussing whether that makes sense, just the situation in the sense of what happens to the landscape and the symbolic value of it)
<B787_300>
BPlayer: i would be fine with that because the Canyon is HUGE
<BPlayer>
*shrug*
<BPlayer>
Can't comment any further on that, then
<B787_300>
BPlayer: a hypothetical i am not cool with is if they were forced to build in Yellowstone over Old Faithful
<SnoopJeDi>
it's a tiny portion of land, but Hawai'i isn't very large to begin with...
<SnoopJeDi>
and the indigenous population isn't exactly unfamiliar with outsiders coming in and dictating what's what :(
<BPlayer>
OTOH, I am the kind of person that would strongly oppose terraforming planets, and rather promote exploration that changes as few things as possible
<SnoopJeDi>
our local astro rockstar summed it up pretty well: "which exploration do you want to miss out on? cultural exploration here at the expense of exploring out-there, or vice versa?"
<BPlayer>
^
<SnoopJeDi>
which came off pretty anti-TMT to me in the moment, since TMT isn't the *only* way to explore the stars, but...it's compliated :/
<BPlayer>
It's a tradeoff in this case
<SnoopJeDi>
infuriatingly, one of our less...aware...students piped up with "can't they just compromise?!"
<SnoopJeDi>
my dude.
<BPlayer>
There is only one Earth we live on. There will be conflicts over this and that
<B787_300>
SnoopJeDi: like I said i would be against it if it was on a grave site but them refusing to give up a bit more of a mountain is annoying as hell to me after TMT offered to build on the footprint of one of the scopes already there
<SnoopJeDi>
I don't have any particularly strong opinion one way or the other, on account of not being an astronomer or Hawaiian.
<SnoopJeDi>
but it's hard not to sympathize with people who have had land basically stolen from them
<BPlayer>
That is pretty much my stance
<SnoopJeDi>
fsvo "stolen" because property is a very thorny concept
<SnoopJeDi>
but like, I know *exactly* how I feel about Dole, for example.
<BPlayer>
Stolen, because they were there for as long as the concept of property exists
<BPlayer>
Property as a concept makes much more sense if you look at it on a larger scale. Hawaii is the property of Hawaiians, rather than parts of Hawaii being the property of individuals

<bofh^28>
I *did* find some ArianeSpace launch videos from 1996 (on Trans*Colour*Video SÉCAM, *snicker*) that are currently being digitized, tho.
<egg>
bofh^28: arianespace doesn't really work if you Camel it
<bofh^28>
wait, why doesn't it?
<egg>
well the nice thing is that naturally reading arianespace as written yields [aʁjanɛspas] in fr, as in "ariane espace"
<egg>
and it also works in en by reading it as "ariane space"
<egg>
bofh^28: so they always write it as a single word (with a single font), contrast with ArianeGroup or arianegroup but with group in a different font, where here there's no pun to make
<egg>
bofh^28: yeah, and it's a pun by elision of the final mute e in ariane, rather than the initial one in espace (which cannot be elided)
<egg>
arian'espace if you will
<egg>
so camels break that
* UmbralRaptop
is confused by the rockets. Is that a Minotaur to the left of the Vega, and why does whatever is to the right of the Ariane 5 have an ISRO vibe?
<egg>
do not put camels in the rocket
<egg>
UmbralRaptop: that's a Союз
<egg>
UmbralRaptop: oh to the *right*
<bofh^28>
egg: AHHHHHHHHHHH
<egg>
UmbralRaptop: that's an Ariane 6
<bofh^28>
I see now.
* UmbralRaptop
pokes egg in the coordinate system
<egg>
UmbralRaptop: and to the left you have Vega and Vega C
<UmbralRaptop>
ah
<egg>
Vega, Vega C, Союз, Ariane 5, Ariane 6
<egg>
UmbralRaptop: if you want a real ISRO vibe you want Ariane 4 though
<egg>
Vikas, or, I can't believe it's not a Viking
<UmbralRaptop>
Heh
<egg>
UmbralRaptop: but yeah, it's an Ariane 6
<egg>
UmbralRaptop: see also the arrangement of the flags on the rocket
<bofh^28>
rofl
<UmbralRaptop>
But did the Ariane 4 have a configuration with LFBs around an SRM core?
<egg>
no, it was liquid core, and a choice of liquid and solid (or a mix) for the boosters, if any
<UmbralRaptop>
egg: interesting flag setup
<egg>
(they were supplemental propellers rather than acceleration stages, not the same kind of "booster")
<egg>
the EAPs are stages, in that the Ariane 5 isn't going to space without them
<egg>
the PALs/PAPs were not, they were optional
<egg>
PAL?
<Qboid>
egg: [PAL] => Propulseur d'Appoint à Liquides
<egg>
PAP?
<Qboid>
egg: [PAP] => Propulseur d'Appoint à Poudre
<egg>
EAP?
<Qboid>
egg: [EAP] => Étage d'Accélération à Poudre
<egg>
UmbralRaptop: the boosters on the Ariane 6 are Vega C first stages iirc
<UmbralRaptop>
Like a Союз or Titan IV?
<UmbralRaptop>
(mandatory "boosters")
<egg>
yeah, the Ariane 5 is like that
<egg>
so it's a powder-based acceleration stage, rather than a powder- or liquid-based booster
<egg>
