bofh^28: making an offering of 0.01 EUR to the gods of shitty eleggtronics,
<egg>
welp, still bootloops

hmm, refreezing after coin insertion gets mee to the boot animation at least

egg: so apparently the gods of shitty eleggtronics have accepted your offering,
<egg>
bofh^28: my offering of cold hard cash
<egg>
bofh^28: it had to be cold though
<egg>
tepid cash is not acceptable
<egg>
bofh^28: also meow, draft, chat, etc.,
<egg>
bofh^28: also re. screening, realized something
<egg>
bofh^28: as a function of r, the force is F r^-k where F depends only on λ and φ
<egg>
bofh^28: but since the force doesn't only depend on r, you do need to integrate back the screened force to get something that does derive from a potential
<egg>
bofh^28: i.e. there are ℜs in the force as well as 𝛁ℜs
<egg>
to use the notation from the principia documentation and uh also the identifiers,
<egg>
bofh^28: so that means that if the sigmoid polynomial is a cubic of r, the ℜ factor will contain logs, which is annoying
<egg>
(at least for smol k)
<egg>
bofh^28: instead, we can make it a cubic in the square root of ℜ, which contains terms in r^n with integer n only for n = 1
<egg>
bofh^28: which is fine, because the terms that we are trying to screen are in r^k for k > 2
<egg>
and r / r^3 = 1 / r^2 which doesn't spawn obnoxious logs
<egg>
bofh^28: \o/

UmbralRaptop: Why do you have a 19 foot table?
<egg>
bofh^28: and I want the maximum for fixed (n,m), not the maximum over (n,m) for fixed z
<egg>
bofh^28: hmmm "Bernstein (1937) proved (A1) with sharp constant C=2/π−−−√; his proof is presented in Orthogonal Polynomials by Szegő, section 7.3.
<egg>
"

but that's the polynomials, not the associated ones

<whitequark>
awang: a bunch
<whitequark>
what about it
<awang>
UmbralRaptop: So in other words you have a *ton* of data and need a table for it?
* awang
thinks that quite a bit flew over their head
<awang>
whitequark: Have you used OpenCV in Rust recently?
<awang>
Found your post on /r/rust about rust-facedetect, but that was quite a while ago
<awang>
Wondering if things have improved/degraded since then
<UmbralRaptop>
awang: yeah. In principle, this means something like 10k spectra.
<whitequark>
opencv nope
<awang>
Considering using Rust for a R&D app instead of C++, and I think that app is going to end up needed to do quite a bit of data/image processing
<awang>
whitequark: what have you been working on in Rust?
<whitequark>
awang: firmware
<awang>
UmbralRaptop: How does spectral data go into tables? I'm most familiar with it as graphs
* egg
meows at whitequark
<UmbralRaptop>
awang: uh, not directly. I'm simulating RV surveys to see if they're a good way to pick up planets for WFIRST / HabEx direct imaging. The table is the observation date, RV value, and precision. But with > 1800 nights, and the longest measurement taking <40 minutes…

what are these bofhsecs?

it seems like some sort of invariant that compiler people are eclectic
