<raptop> ...maybe I should have used the one with gigabit ethernet for this.
* raptop is saturating a 100 Mbit connection
* raptop ignores that that raptop has only a 60 gig disk, and only like 2.1 gig free (verses the 80 free on a 90 gig drive on this one)
<SnoopJeDi> downloading something, raptop?
<raptop> Bunch of partially processed simulation data, because it'll be useful for throwing it at some other machines to finish processing.
<SnoopJeDi> \o/
<raptop> Also realizing that exploiting a bunch of extra compute means installing far too many snek packages
<SnoopJeDi> I realized after getting this server set up and named 'lawrence' that I missed a good naming opportunity. There are two of these, so naming them courant and snyder would be even more of an historical nod

* raptop stares at their last 4 computer names. Silbervogel, Keldysh, Urvogel, Eoraptor
<raptop> (Well, ones that I actually named. 55_CnC doesn't count)
<SnoopJeDi> o.O
<raptop> *55-Cnc
<raptop> As in 55-Cancri, as in that star with a notable early detection of a hot superearth. That may have a thin atmosphere, a thick atmosphere, or a dayside lava ocean. o_O
<raptop> Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-rtk2uocw/radvel/
<raptop> Note to self, setting up eggs is hard.
<raptop> ...so many dependencies >_<
<SnoopJeDi> no pip?
<SnoopJeDi> oh nevermind, says pip-install right there >_>
<raptop> pip and conda

<SilverFox> so real talk, I was mulling over some wine and it hit me, how do you reference a point in memory, at a very very low level, without it basically being a doubling effect, where you have data, and then pointer
<SilverFox> or is that just how it goes
<SnoopJeDi> SilverFox, what do you mean?
<SilverFox> like, you have a byte in memory, but if you think of it from a programming language, you need to reference that memory
e_14159 has joined #kspacademia
<SnoopJeDi> well, you go to that address and read the right amount of memory then, yea.
<SilverFox> yeah but that requires another byte* to reference the memory
<SnoopJeDi> yes
<SnoopJeDi> but the size of a pointer is often going to be small compared to the data
<SilverFox> and if you give a name to that reference, does that require more memory, or do compilers just skip this step and translate any reference to the thing as a direct address pointer?
<SnoopJeDi> I don't really grok compilers but I think the answer is "it depends"
e_14159_ has quit [Ping timeout: 202 seconds]
<SnoopJeDi> err, unless you're just asking about `foo = &bar;` in which case that's meant for human consumption and isn't particularly meaningful to the output the compiler, AFAIK?
<SilverFox> that's what I figured
UmbralRaptop has joined #kspacademia
<SilverFox> now, do modern compilers, since MUH SECURITY N SHIT, work with dynamic memory addresses or static addresses?
<SnoopJeDi> SilverFox, I found this video to be a fun romp through assemblyland: https://www.youtube.com/watch?v=yOyaJXpAYZQ
RadvelRaptor has quit [Ping timeout: 202 seconds]
<SnoopJeDi> and I think the answer to that second question is "both" (modulo the fact that the "static" stuff is usually in terms of offsets)
<SnoopJeDi> but like, creating a stack/heap that live in a fixed place is a very sensible thing for a compiler to be doing, as is "jump to an address indicated by a value held in memory"
<SnoopJeDi> and happily, the compiler lets us express those things in terms that...aren't machine instructions. Math: it works!
<SnoopJeDi> there's uh
<SnoopJeDi> also TIS-100 to scratch this itch
<oeuf> !wpn whitequark
* Qboid gives whitequark a helicoid
<B787_300> UmbralRaptop: i mean why not... large FoV, good sensitivity, so it can spot the supernovae before visible from ground based telescopes? i can see it until someone makes a set of all sky all the time* telescopes
<UmbralRaptop> B787_300: it totally works for secondary science, I was just amused by the description as the 'real mission'
<egg|cell|egg> UmbralRaptor: setting me up is hard?
<B787_300> ah
<UmbralRaptop> egg|cell|egg: snek language silliness
<B787_300> just think about all the secondary and tertiary science that can be done if all the worlds telescope images were all archived and accessible
<UmbralRaptop> B787_300: :D
<B787_300> huh i wonder if that could be a viable buisness model... set up a set of say .25-.5 m robotic telescopes, sell access for pointing rights, also store all images in a very large database and sell subscriptions to said database
<B787_300> set it up with either big enough FoVs that you get enough stars for Photometric cal or require that 3-4 times a night the scopes take a photometric cal set
<iximeow> ooo i like this
<B787_300> i request a small cut of profits if anyone in this channel uses my idea
<B787_300> say 2-5%
<B787_300> you would need to have a technician or two at each site to troubleshoot / fix, but each tech could probably fix/watch over what 10 or so scopes?
* UmbralRaptop wants to say that this eggsists
<B787_300> oh i know robotic scopes exist that you can buy time on
<B787_300> i am thinking more of the DB to "double dip"
<UmbralRaptop> Ah
<B787_300> could have differing levels of DB access, one level is just star / object brightness / loc, another level is X numbers of raw images a $timeperiod
<B787_300> oh and make it so that random people could submit images and store them as unverified addtional data
<B787_300> or if you can run them through a system like astronometry.net to get location data / photometrics then add them to the main data

<SnoopJeDi> bofh, ...I really want to hear a somber organ composition of nyancat now???
<B787_300> SnoopJeDi: in a minor key too right?
<SnoopJeDi> probably
<SnoopJeDi> "minor key" and somber are close enough to synomymous :P
<SnoopJeDi> synonymous, too
<B787_300> Have you never heard supossdely happy songs transcribed into minor key and played? They sounds realllllllly dark
<SnoopJeDi> I have
<B787_300> I think the nyancat tempo will cause issues though
<SnoopJeDi> Happy birthday is particularly delightful
<SnoopJeDi> yea, you'd definitely have to dial it back

<SilverFox> oh great math geniuses, do you guys have an equivalent to the "indian guy coding tutorial"?
<SilverFox> is it a russian professor with a chalkboard?
* raptop blinks in confusion
* raptop also had a russian professor at a whiteboard for a class last semester. it was actually pretty reasonable
<SilverFox> when you look up coding tutorials on youtube, the common trope is that you will get an indian dude tellin you how to code things
<SilverFox> what's the equivalent for math tutorials
<SilverFox> (other than that khan academy thing)
<SnoopJeDi> open courses I guess?
<SnoopJeDi> which I mean, those exist for programming, too.
<raptop> Getting a lecture by a clone of Grothendieck
<SnoopJeDi> 3brown1blue does a good job with making things digestible, too

<B787_300> SilverFox: there is that one American dude for basic calculus tutorials
<SilverFox> "that one american dude" isn't a stereotype
<SilverFox> I want a stereotype for who you get when you look up math tutorials on youtube
<raptop> ...okay, these additional fancy boxen I can use don't have tmux. Great...
* raptop should probably learn how to use nohup?
<bofh> UHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
<bofh> so somehow I suspected this dodgy "24VAC" transformer that came with this LED light strand is, in fact, actually a capacitative dropper.
<bofh> I connect it to an oscilloscope.
<bofh> 0V.
<bofh> move ot AC coupling, ~500mV peak-peak
<bofh> connect an LED against it and now it's drawing 3.5V
<bofh> accidentally brush my finger against it and there's a mild stinging AND THE DIFFERENTIAL FOR THE ROOM GOES OFF
<bofh> welp that's going DIRECTLY INTO THE TRASH.
<SnoopJeDi> aaaaAAAAAAAAAAAAAAA
<whitequark> nice.
<raptop> O_o O_O o_O
<bofh> how to tell your voltage step-down device is a Kwality product: there is full continuity between phase and one of the output pins.
<bofh> pretty sure the only thin in that path is a single diode.
<SilverFox> jesus christ
<SilverFox> bofh, hold up
<SilverFox> "240V USB outlet"
<bofh> seen them, got shocked by one even.
<bofh> ground directly referenced to neutral & North America doesn't do differential breakers outside of bathrooms.
<SilverFox> out of bathrooms or places where outlets are in x proximity to water sources iirc
<bofh> like, it's good that they're there but I don't understand why they keep ignoring the case of "what if some idiot thinks putting a capacitative dropper in a brick, labelling it 24V and then selling it to people where it then proceeds to electrocute all their fish" as one that's utterly irrelevant
<bofh> seriously oeuf how DOES one contact the FR electrical inspection authority? I'm pretty sure selling capacitative droppers directly referenced to a mains pin as "24VAC" adapters isn't, erm, allowed.
<bofh> (that moment when your impromptu electrical install into Montsouris streetlights is actually up to code and stuff I bought in Quatre Temps eggstremely is not).

<oeuf> bofh: have you joined the sigfig weird chat
<UmbralRaptop> yet another chat program? bleagh

<oeuf> bofh: "the orbit stuff is decidedly not intellectual property so theres no point in not doing it in public" quoth the sigfig
<oeuf> UmbralRaptop: its *weird* but it supports LaTeX, so
* raptop 's internet options are really lacking, so this could be a problem.
<oeuf> UmbralRaptop: internet options?
<raptop> Well, no home internet at the moment...
* oeuf pets raptop
* raptop murrhs
* raptop stabs things
* raptop wonders why the vim install is missing things like colorschemes, and seems to silently eat commands like :bn
<SnoopJeDi> raptop, is it actually vim?
<SnoopJeDi> I mean, :bn should *probably* work everywhere, but there are things like vim-tiny and busybox's vim that are pared back
<raptop> SnoopJeDi: it claims to be vim 7.4.1099
<raptop> The help options mentioned in the start screen don't work o_O
<raptop> ...also, apparently I need to start it with 'vi'. Using 'vim' gets a command no found error.
<SnoopJeDi> o.o
<raptop> Oh, right. GMU uses RHEL, so we have yum, not apt-get
