<UmbralRaptor> This matrix is clearly hermitian also.

<B787_300> is their logo a bird?

<raptop> ;8ball Did I break the cluster again?
<kmath> raptop: Concentrate and ask again
* raptop pours orange juice on kmath
<raptop> Yeah, I think I ran the main node out of disk space >_> <_<
* raptop should probably stop beating HDDs to death with markov chains.
<e_14159> raptop: The whole cluster?
<raptop> e_14159: just the main node, but directly sshing into the others is, uh, nontrivial?
<e_14159> I'm now wondering whether that could happen on our cluster.
<e_14159> Nontrivially, I think, for my home folder (contrary to the others') isn't on the nfs so I should always be able to login.
<e_14159> What did you store on there?
<raptop> various fitting results. They're not especially time important, so I can just poke IT on Monday.
<raptop> ...also, I think I need to cull the chains more agressively.
<bofh> egg|zzz|egg: yes but what is the difference between FORM ONE and FORM TWO?
<egg|zzz|egg> bofh: there's no FORM ONE; NEPTUNE is ♆, an NEPTUNE FORM TWO is the proper symbol, see the bottom of the table https://en.wikipedia.org/wiki/Astronomical_symbols#Symbols_for_the_planets
<egg|zzz|egg> the symbol that corresponds to ♅ :-p
<egg|zzz|egg> bofh: the symbol for Le Verrier
<bofh> okay, so now my question is why the hell the encoded symbol is the trident instead of the proper planetary symbol.
<bofh> seeing as the symbol encoded for Herschel is the proper one instead of the Platinum element one.

<APlayer> Just to clarify - a * log(b x) = log(b x + e^a)?
egg|cell|egg has quit [Ping timeout: 190 seconds]
<APlayer> No, it's in fact not
<bofh> egg|zzz|egg: rofl
<egg|zzz|egg> bofh: are you rofling at Astronomische Nachrichten or at the commit messages
<raptop> APlayer to confirm: a * log(b x) = log( (b x)^a )
<APlayer> ...oh.
<APlayer> I see, thank you
<APlayer> a + log(b x) would have been log(b x * e^a), I mixed up the operators
<raptop> yeah
<APlayer> So if log "converts" + to * and * to ^, what happens with ^? If you do a^log(b x), you eliminate the exponentiation and the log and end up with some factor I am too lazy to calculate. But why? I mean, + and * are being "stepped up", if that's a way of expressing it. And ^ is just being eliminated? Or am I thinking wrong when I say you want a^log?
<raptop> I think you need additional operators (ping the mathematicians?). I, uh, don't know where you'd run into an a^log(f(x)), though I suppose that there's a chance of log(f(x))^a.
<mlbaker> it's more accurate to say log converts * to +. exp converts + to *.
<APlayer> Well, yes
<mlbaker> it converts * to ^ kind of because it has to
<mlbaker> ugh
<mlbaker> i mean, it converts ^ to *
<mlbaker> ^ is iterated multiplication: log(c^n) = log(c*c*...*c) = [log c]+...+[log c] = n log c
<APlayer> Everything in maths happens because it has to :P
