<SilverFox>
that's not that small a tumour either
<SilverFox>
it's not large but hot damn
<SnoopJeDi>
yea, if FOLFOX and other chemo are carpet bombing, this is a cruise missile
<SilverFox>
apparently
<SnoopJeDi>
because as I understand it it only really messes with the mutated receptor kinases
<SilverFox>
pretty epic
<SilverFox>
I'm not seeing any other damages to the area as collateral
<SilverFox>
both hemispheres look healthy
<SnoopJeDi>
I don't grok enough microbio to really read the specifics but my understanding is that the gene fusion pastes some garbage onto the tail end of the kinase, and that causes hell because of TRK's role in the signaling cascade
<SilverFox>
with genes it's really easy to screw with and just mess up the whole thing
<SnoopJeDi>
but it also makes the target morphologically distinct from healthy tissue in a predictable way (there are particular flavors of TRK fusions but they're all related-ish), so you can design a drug with high affinity for fused complexes and no affinity for others
<SilverFox>
a single insertion throws everything afterwards off
<Ellied>
I'm annoyed by how twitchy IRCers are about asking-to-ask, tbh. I go into #sagemath and say "hey, is this the right place to ask about Jupyter Notebook problems?" and get someone's aliased copypasta about why exactly I fucked up by asking to ask.
<SnoopJeDi>
AIUI a single basepair insertion would be caught by proofreading fairly easily, unless by "insertion" you mean a sequence
<SilverFox>
insertion is any amount added
<Ellied>
If I'd come in and asked about the wrong thing straight out, I assume I would have been similarly railed against. You kinda can't win sometimes
<SilverFox>
could be a single base pair, or multiple
<SnoopJeDi>
all I know is that this happens because of crossover problems where large segments are spliced in
<SnoopJeDi>
and it becomes a problem for such-and-such discrete set of fusions. presumably others happen but are caught by proofreading or don't cause anomalous life cycle or...
<SilverFox>
SnoopJeDi, I love the name of the global trial going on: "STARTTRK-2"
<SilverFox>
STARTRK-2*
<SnoopJeDi>
same
<SnoopJeDi>
alas, dad is not a trekkie
<SilverFox>
so they've opened up the study from just neuroblastomas to other types as well
<SnoopJeDi>
Although I think I did manage to drag him to see Beyond
<SnoopJeDi>
it's in Phase II now SilverFox but I don't know so much about the global stuff. His cancer is colorectal with peritoneal metastasis, which is very much not-neuroblastoma
<SilverFox>
indeed
<SnoopJeDi>
the only other not-FOLFOX treatment I'm aware of for peritoneal cancers is HIPEC, which can be summarized as "cut the patient open, dump chemo drugs directly into peritoneal sac, increase body temp and literally rock the patient back and forth for a while"

<SnoopJeDi>
staying in touch with local governance is a good way to start, since the issues are literally closer to home

<APlayer>
Well, as I said. I am absolutely not interested in politics and will tend to interact with it at the barest minimum.

Uh, Ellied, not sure if I actually asked or only thought about doing it... Is there an electrical component that amplifies an analog signal? I.e. like an enhancement mode MOSFET but with more than just on or off capability
<Ellied>
bofh: has no one?
<SnoopJeDi>
I can only govern my own behavior, and I'm just offering an explanation for what I saw as a legitimate inquiry
<Ellied>
bofh: microcenter sells those parallel fairy lights, those would be easy to run with a joule thief if it could handle the current (big inductor I guess)
<bofh>
Ellied: I'unno, I feel like it's obvious yet I can't *think* of any, granted I don't shop much, let alone for xmas crap.
<bofh>
Ellied: yep, or lo-current LEDs, even.
<SnoopJeDi>
Ellied, same, I don't think I know a single colleague who would not fit that mold
<Ellied>
well, the LEDs (for green and blue) are already quite efficient, but getting them decently bright requires at least 1 mA per diode or so, which adds up quick. I think the strands are like 50 or 100 usually?
<APlayer>
SnoopJeDi: Well, that's politics for you. Our opinions differ, and I don't think that it's possible for us to agree

AIUI the existence of a political field in a quantum vacuum is an open problem in poli sci
<APlayer>
Ellied: Did you receive my question? Not pressing for an answer, would be just nice if you acknowledged it and answered whenever you feel like it
<Ellied>
APlayer: so MOSFETs already do have a roughly-linear relationship between gate voltage and drain
<SnoopJeDi>
UmbralRaptor, have you read The Design of Everyday Things? it's already on my to-read, but I have a recommendation shelf now
<Ellied>
current if you're just barely above the threshold
<UmbralRaptor>
SnoopJeDi: yeah, also Turn Signals are the Expressions of Cars (IIRC)
<Ellied>
but for actual linear (amplifier) applications, you probably want a BJT (linear current-to-current) or JFET (linear voltage-to-current)
<APlayer>
Okay, I'll look those up
<bofh>
JFETs are super-nice.
<APlayer>
Just a very long term thought I had here
<bofh>
very simple depletion-mode devices that often swap cleanly in for a triode.
<SnoopJeDi>
I have a bunch of designer friends who rave about that doc "Helvetica"
<APlayer>
Thanks for the recommendations!
<SnoopJeDi>
well, a few
<APlayer>
Also, thanks SnoopJeDi for the talk!
<APlayer>
I'm off for today, then :-)
<SnoopJeDi>
you're welcome, thanks for listening to my screed :P

gives bofh a helicoid
<SnoopJeDi>
UmbralRaptor, hmm between the two which would you recommend? I'm trying to keep this shelf SOMEWHAT orderly
<Ellied>
If you want to amplify audio, I think a BJT is more what you're after[citation needed] because they tend to be more tolerant of high current and you don't need the hugely-high-impedance capabilities of a JFET[citation needed]
<SnoopJeDi>
despite knowing that ΔS_{Goodreads} ⋙ 0
<UmbralRaptor>
SnoopJeDi: this was like a decade (or more) ago, so not sure.
<SnoopJeDi>
mkay, I'll stick to the former since I had it on my list to begin with
<UmbralRaptor>
I think the first one?
<bofh>
Reminds me, I need to setup a goodreads myself.

!wpn add:adj extended

!wpn -add:adj extended

Lol

<egg>
bofh: so, do you happen to know a standard/readable way to force a truncation from extended format to binary64?
<egg>
um, s/truncation/rounding/ rather
<bofh>
egg: a typecast?
<egg>
if only
<egg>
bofh: some compilers like to keep things on the x87 stack even when they say double
<egg>
going through a volatile works, but I wonder whether it can be made readable
<egg>
(also this sounds extremely funny in french where volatile the noun means bird)
<egg>
initially to abstract compensated summation, then we started needing a true double-double sum
<rqou>
what is wrong with you
<egg>
to be used with care (it's *not* correctly-rounded), but useful
<egg>
rqou: well I am a talking egg, to start with,
<rqou>
also, my template-fu is too weak and i can't tell wtf is happening there at all
<egg>
ah yes principia has rather intricate template porn
<egg>
rqou: it's a double precision T
<rqou>
ok, at least you didn't bake double-double into a compiler ABI
<rqou>
*cough* *cough* ibm
<egg>
rqou: e.g. you can have a double precision Position<SomeFrame>, or Instant, or Length (or double!)
<egg>
(in other words it interacts nicely with our typing of physical quantities and geometry)
<SnoopJeDi>
building on mingw...
* SnoopJeDi
shudders
<egg>
rqou: Difference<T> is the type of the difference of two Ts, Product<T, U> the type of the product of a T and an U, (since everything has fancy typing those aliases are vital)
<rqou>
mingw kinda works well enough enough of the time :P
<egg>
rqou: e.g. a difference of positions is a displacement, a product of velocity and time is a displacement, etc.
<rqou>
and the tangent space stuff you were explaining earlier? :P
<rqou>
(i'm currently studying for my midterm/final tomorrow morning
<rqou>
i hate this class
<egg>
um well the tangent space is a vector space?
<egg>
(at every point)
<egg>
(which gives you a tangent bundle)
<rqou>
iirc you got stuck on explaining this last time
