it's a pink-feathered stegosaurid

UmbralRaptor: there seems to be correlations between the themes of successive books: Summaries when it counts, The true summaries, Errors in summaries
<egg|df|egg>
UmbralRaptor: also Probing and beyond, Mastering probing, The future of probing, The hidden meaning of probing
<egg|df|egg>
the latest book seems to be Pathways to Daylight and the Seasons, on the variation of daylight with the seasons

I *finally* figured out why diodebot was crashing
<Ellied>
Twitter rejects duplicate tweets, so it was throwing an error every time it tried to post something it had posted before.
<Ellied>
Not sure what the details of the associated criteria are, but it was trivial to except out anyway.
<UmbralRaptor>
I think it's posted 3 nociceptive diodes. >_>

egg: wow, that thesis overloads a lot of acronyms
<soundnfury>
AI, CSS, SQL... heck, even GSO has a different meaning to me (albeit in a somewhat narrow context - Generalised Segmentation Offload ;)
<soundnfury>
oh also MOT, I guess
<egg>
GSO?
* egg
pokes Qboid
<egg>
there's Guan Sheng Optical :-p
<soundnfury>
GSO is like TSO but implemented by the network stack instead of by the hardware. Among other things, it losslessly reverses GRO (Generic Receive Offload), which is important for forwarding workloads.
<soundnfury>
(However, GRO for forwarding is a dumb idea, which is part of why I'm pushing for SKB-list handling to replace GRO.)

UmbralRaptor: hmm, I am starting a comment by // This function does unnatural things
<UmbralRaptor>
Is it a Weierstrass function?
<egg>
UmbralRaptor: nah it just does things like that because we don't have the right abstractions for rendering
<egg>
UmbralRaptor: yet
<egg>
UmbralRaptor: but phl is writing some projective geometry as we speak
<egg>
UmbralRaptor: yes that means principia is going to have its own rendering code in a sense
<egg>
(because the current implementation has to horribly misuse our abstractions in order to get back to the Unity cameras
<egg>
UmbralRaptor: see, we transform to some plotting frame (say ECEF); and instead of saying "the camera is fixed in ECEF, we do the projection of the ECEF trajectory", we go back from ECEF to """world""" coordinates (via solar system barycentric coordinates), but at a fixed time (basically pretending that there are actual positions marked in low earth orbit with a cosmic fluorescent marker)
<egg>
and then the C# does the rendering from those world coordinates
<UmbralRaptor>
hrm
<egg>
UmbralRaptor: so clearly just saying "the camera is fixed in ECEF" is saner
<egg>
that will also allow us to implement a downsampling algorithm to render a decent number of points instead of making things grind down to a halt as soon as history is plotted

UmbralRaptor: fused multiply and add
<egg>
UmbralRaptor: usually you deal with single operations such as (here [] shall denote exact rounding to the current rounding mode) [x+y] [x*y] [x/y] [sqrt(x)]; fused multiply and add provides you with [x*y+z]
<egg>
UmbralRaptor: from which it is easily seen that [x*y-[x*y]] is the rounding of the difference between x*y and [x*y]; the slightly tricky part is to show that there's no rounding going on here, i.e., that this difference is representable; this is because if you multiply a 53-bit number by a 53-bit number, you get a 106-bit number
<egg>
thus [x*y-[x*y]] = x*y-[x*y], quod erat demonstrandum
