* awang
meows
<egg>
bofh: awang wants to learn about numerics (hence the meowing), do you have any good pointers?
<B787_300>
numerics? as in numerical integration?
<egg>
well, more generally numerical analysis
<egg>
and floating-point madness, etc.
<egg>
I could probably give awang some pointer but I should sleep
<egg>
and bofh certainly can
<UmbralRaptop>
say, 0x5F3759DF?
<bofh>
egg: uhh what bit specifically? ieee754? error analysis? numerical linalg? ffts? interpolation/integration?
<egg>
awang: meow more specifically
<egg>
UmbralRaptop: get a new bird
<egg>
bofh: I mean, why not all of it :D
<awang>
Uhhhh
<awang>
egg: I would prefer my brain not explode :P
<bofh>
(and like part of the problem is I don't have a good general-purpose numerics reference to throw at people, I picked up all this stuff from a zillion random places, some of it even by observation)
<bofh>
(I should really ask Atlas about this, come to think of it)
<egg>
bofh: I mean, same, whatever lecture notes I have are in german
<awang>
What maths should I know before learning numerical integration?
<awang>
Beceause I'm pretty sure I don't know them
<egg>
first-year Calculus?
<awang>
Oh, got that
<awang>
Been quite a while though
<egg>
aka Analysis I for which I have lecture notes in German
<egg>
bofh: I mean, we should get Atlas in here, yes
<egg>
bofh: but you probably can eggsplain some things to awang in the meantime
<egg>
bofh: what kind of cat food attracts numericists
<bofh>
numerical integration? like calc I for the simple algorithms & maybe a bit of complex analysis & linalg for Gaussian Quadrature?
<egg>
bofh: meh you don't need the complex analysis
<bofh>
yeah, on second thought, yeah.
<egg>
(unless you want to start raving about A- and B- and L-stability I guess)
<egg>
but then you need that even for RK methods
<egg>
!wpn -add:adj A-stable
<Qboid>
egg: Adjective added!
<egg>
!wpn -add:adj L-stable
<Qboid>
egg: Adjective added!
<egg>
!wpn -add:adj B-stable
<Qboid>
egg: Adjective added!
<UmbralRaptop>
A-, B-, and L-stability?
<egg>
yes
<egg>
A-stabil!
<UmbralRaptop>
(Ignore that I'm half busy with random legal paperwork)
<egg>
bofh: although for *practical* numerical analysis I'd recommend some command of FP things, because you will need compensated summations (and in some methods, bona fide double double)
<UmbralRaptop>
Okay, EN Wikipedia also has an article.
<bofh>
egg: true.
<bofh>
extremely true, in fact.
<egg>
bofh: and error analysis is always useful, so,
<egg>
now, once you've integrated something you'll sometimes want to interpolate it to treat the result as a continuous function,
<egg>
bofh: so basically it's just the FFTs that you don't need at this point :D
<egg>
bofh: s/ex/eggs/
<Qboid>
egg thinks bofh meant to say: eggstremely true, in fact.
<bofh>
tl;dr a Cisco kernel-mode driver fails to correctly save/restore FP state, fucking it up at random in the process
<bofh>
AAAAAAAAAAAAAAAAAAAA it's not even that, it calls MMX instructions but never runs emms, and this means that fp state is fucked (MMX registers overlap x87's registers in reverse order).
<egg>
bofh: anyway you can teach awang about forward and backward error analysis, that's always fun
