<UmbralRaptop> … for a channel named "academia", we have surprisingly few academics
<UmbralRaptop> (also, I think only one person with a PhD)
<UmbralRaptop> (not me)
<SilverFox> who has the PhD?
<SilverFox> and is it something worth having a PhD in?
<SilverFox> f(x) = first line of I Want It That Way by Backstreet boys
<UmbralRaptop> Some lepidopteran, and chemistry, so I'm not sure what their job prospects are
<SilverFox> chemistry definitely is a decent one
<SilverFox> lots of places to go with a chemistry degree
<SilverFox> question real quick
<SilverFox> how did apple fall on newton's head if gravity wasn't invented yet???
<SilverFox> UmbralRaptop, I have a self-given PhD in shit-posting
<SilverFox> does that count?
<UmbralRaptop> Is SilverFox University an officially accredited institution?
<SilverFox> uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
<SilverFox> tis now
<SilverFox> I officially decree it so
<SilverFox> as the dean of said institution
<SilverFox> I guess you'd call it an Honorary PhD
<UmbralRaptop> Also, there were gravity implementations at least as far back as Aristotle
<SilverFox> question resolved
<SilverFox> thank you good denizen of the interwebs
<UmbralRaptop> (Hopefully apple had updated to include the Kepler and Galileo patches by then)
<UmbralRaptop> tfw you get a recruiting email that makes it clear that someone is using a 7-9 year old copy of your resume
<SilverFox> golden

* egg glares at the bot
<mofh> egg: not offhand, also that is a very weirdly specific matrix, where is it coming up?
<egg> mofh: from trying to flip e1 (and keeping handedness, so e3 too)
<egg> (or trynig to flip e3)
<egg> mofh: conteggst: rigid body rotation

<mofh> egg|zzz|egg: I mean my point is that purely diagonal matrices generally aren't interesting enough to have special names
<mofh> egg|zzz|egg: also I've had a wild/hectic past few days, apologies for not being around really
<egg|zzz|egg> mofh: well apparently there is a name, see backlog
<mofh> let me get that whiteboard stuff to you now
<mofh> yeah I'm legitimately surprised at that
<egg|zzz|egg> so I guess geometry::Signature
<egg|zzz|egg> which will be implemented as three geometry::Sign
<egg|zzz|egg> (which I really need to change so it actually takes the sign bit instead of comparing with 0....)
<SilverFox> how low-level can functional programming languages go?
<mlbaker> signature matrix lol
<mlbaker> makes sense i guess
<whitequark> define functional
<whitequark> take a look at Habit (the haskell dialect)
<SilverFox> like haskell
<egg|zzz|egg> mlbaker: it's made of signs! clearly we can generalize this, if you have a matrix with squares on the diagonal it should be a quadrature matrix,
