<SnoopJeDi> Iskierka, you could probably extend that to any sufficiently distinct subnetwork. Fandoms etc.
<Iskierka> fandoms sure, it's more interesting with groups who theoretically don't have reason to get together because eg. pre-diagnosis
<SnoopJeDi> ah
<SnoopJeDi> That's...a really interesting idea. Medical graph theory.
<Iskierka> it's strongly exhibited with "rapid onset gender dysphoria" (read: trans people pre coming out tend to be friends with others, and one coming out will encourage the others to do so also)

<APlayer> BTW, Ellied, could you help me identify this part? It looks a bit like a through-hole mount resistor, package is of similar size and shape (perhaps a bit longer), but just a plain, medium grey cylinder. On that cylinder it says 1R00 / FRJ / 8437E / W80S in light grey text. I can't seem to find this on Google, though
<bofh> egg: misread that as "thulium Falcon"
<APlayer> It seems to have a constant resistance of 2 Ohm or so in either direction, but I only looked at it with a multimeter, so it's hard to tell if it's a resistor or something else
<whitequark> APlayer: that seems like... a resistor
<APlayer> Could be a small inductor, or something I don't know about, though
<whitequark> with 1R00 marking?
<whitequark> looks like this? http://www.vishay.com/docs/31016/frj.pdf
<APlayer> Not quite
<whitequark> yeah, that's FRJ-50
<whitequark> and you have a FRJ-8437 (?)

<kmath> <stephentyrone> @bofh453 The hits keep coming. Try this one out: ⏎ 1. Compute SVD to get condition number. ⏎ 2. Use condition number to… https://t.co/egBcbk2Fpw
<whitequark> pretty sure it's a resistor
<whitequark> not sure why it measures 2 ohms though
<whitequark> shitty meter?
<APlayer> Pretty long leads
<APlayer> Long and thin
<whitequark> nah
<APlayer> Definitely has an impact, I've noticed this before
<whitequark> those are in tens of milliohms at worst
<whitequark> go look up conductivity of copper or tin or whatever these leads are made of and compute how large the resistance is.
<APlayer> Nope, way more. Had to approach zero ohm for a thing, and was pleasantly surprised that the remaining few ohms disappeared if I removed the leads and took a shorter connector
<whitequark> and how do you know that's not contact resistance?
<APlayer> The 2 ohms now?
<whitequark> no, "the remaining few ohms" above
<whitequark> because that's definitely not lead resistance
<APlayer> Might be from the connections inside the leads
<whitequark> inside??
<whitequark> !u −
<Qboid> U+2212 MINUS SIGN (−)
<APlayer> Those are normal plugs with long wires and separately attached probes. The wire->probe plug might have a resistance
<whitequark> !u -
<Qboid> U+002D HYPHEN-MINUS (-)
<APlayer> Well, not inside, but suggest a better word :P
<whitequark> let's say you have copper leads that are 0.3 mm in diameter and 50 mm long
<whitequark> > 1.68e-8 ohm*m / (pi*((0.3mm)^2)/2) * 5cm
<whitequark> approx. 5.941784 milliohm (resistance)
<whitequark> an order of magnitude smaller than my inital guess, even
<whitequark> and three orders of magnitude smaller than "remaining few ohms"
<APlayer> It's about 1m of wire, I think. But alright, not 2 ohms, point taken
<whitequark> ah, you meant meter leads, not component leads
<whitequark> those are longer but also thicker, and they're more thicker than longer
tawny has joined #kspacademia
<APlayer> Anyway, the multimeter is a good one. It was used at a military grade production site but was decommissioned as "broken". No idea why it was labelled this way, but the readings it provides are good.
<egg> !choose zzz|dff
<Qboid> egg: Your options are: zzz, dff. My choice: zzz
<egg> s/ff/f
<Qboid> egg meant to say: !choose zzz|df
<APlayer> Good night egg! :-)
egg is now known as egg|z|egg
<egg|z|egg> meow
<APlayer> whitequark: I doubt it's contact resistance too, I stripped a layer of oxides from the component leads (you can even see it in the image), and I moved the leads this way and that. Goes up to 5 Ohms (rarely) and occasionally down to 1.6 or so Ohms. But no less than that.
<whitequark> that sounds exactly like contact resistance plus some other thing
<whitequark> e.g. contact resistance and your meter being crap
<APlayer> The 5 ohm part, yes
<APlayer> But it stabilizes at 1.6 + a few 100 mOhm
<APlayer> And, as I said, the meter cannot be crap
<APlayer> With semi-good contact, I can short the probes and get 0.6 Ohm
<whitequark> it literally was decommissioned as broken
<whitequark> of course it can be crap
<whitequark> also
<whitequark> "With semi-good contact, I can short the probes and get 0.6 Ohm" plus "Goes up to 5 Ohms (rarely) and occasionally down to 1.6 or so Ohms"
<whitequark> combine to "this is a 1.00 ohm resistor, exactly as it says on the tin"
<APlayer> So that's the meaning of 1R00?
<whitequark> of course
<whitequark> that's the standard marking
<whitequark> R stands for decimal point
<APlayer> TBH, the standard marking I know would be black-brown-black-golden
<whitequark> not all resistors are color-coded
<whitequark> none of the SMD ones are
<whitequark> also, it's not golden
<whitequark> if it says 1R00 then it's at least 1%
<APlayer> I'm not even talking about SMD. The markings on those remain black magic, to me
<whitequark> the EIA 1% markings are a simple mapping
<whitequark> the rest is mantissa plus exponent
<APlayer> Humm, I see
<APlayer> Well, at least /that/ is clear now
<APlayer> Thanks, and sorry for being thick, haha
