00:18 < docl> pack to the 4-mer printer idea: actually maybe the sorting can happen as you print. you could pass the mixture of all 256 4-mers through a capillary tube and line the walls with anchored versions of all 256 4-mers clustered in specific zones, so they tend to slow down their complimentary set as it passes. then you could heat up the zone you don't want this happening on, i.e. the one complimentary to 
00:18 < docl> the one you're printing, so it gets less delayed than the others and thus ends up in the droplet getting ejected. that lets you print from a single cartridge.

07:33 < darsie> stipa: Stellarators are a promising tech, IMHO.
07:34 < L29Ah> certainly a better tax money sinkhole than paying police for policing your shoelaces
07:51 < stipa> darsie: they'll need to burn a lot more of hydrogen for it to boil some water
07:52 < stipa> something like hydrogen generator is much more efficient in that case rn
07:53 < stipa> like this stuff https://h2sys.fr/en/products/hydrogen-powered-generator-sets/
07:55 < stipa> so, eventually if they ever come up with the working fusion it'll probably be a hydrogen oven that boils water
07:57 < stipa> so, it'll just give less that is put in it out, since electricity and hydrogen need energy to produce
07:58 < stipa> instead of just running a steam engine on hydrogen directly
07:59 < stipa> and saving on electricity
07:59 < stipa> probably not using at all
07:59 < stipa> of electricity
07:59 < stipa> it's not just a tax sinkhole but also wastes resources if it ever gets working

08:31 < docl> eh, it could actually work. in which case we might be able to move to a more high throughput energy economy, which is a good thing. but we're trying to do something that wants to happen at supernova scale in a building on a planet, which is uh not the easiest engineering feat
08:33 < docl> IMO you get better results trying to implement ultra hot fusion (this is way hotter than the sun) in space. could be done with mirrors and a glass sphere. the mirrors could be 1km away.
08:34 < docl> but it's not popular to invest in serious projects in space, doesn't fit the comfortable university-govt coalitional forces too well
08:34 < hprmbridge> lachlan> How would that work?
08:42 < muurkha> are you proposing igniting a new gravity-bound star?
08:42 < muurkha> or containment glass that withstands the temperatures of the core of the sun?
08:44 < docl> well, I'm not sure about the glass sphere. the basic idea is that you use a shell far enough from the fusion zone that it's a significantly lower temperature in effect (i.e. lots less of the photons or high speed hydrogens per sqm)
08:45 < hprmbridge> lachlan> The walls of the chamber aren’t the blocker for fusion
08:45 < muurkha> okay, but how do you make the fusion zone?  hot plasma tends to expand when not confined
08:45 < docl> no, the issue is heat loss
08:47 < docl> you have a heck of a lot of photons coming back by the time they reach the center, so there's light pressure accelerating the light elements towards the center
08:47 < muurkha> your proposal is to confine the fusion fuel with its own light pressure?
08:48 < docl> yes, after deflection
08:48 < muurkha> that seems backwards because blackbody radiation is isotropic but increases with temperature
08:49 < docl> you also get multiple use of the same photonic energy for this
08:49 < muurkha> I don't see that the mirrors help enough, intuitively.  where are your calculations?
08:49 < docl> I'm a little mystified as to why it wouldn't work with blackbody but reflection seems doable enough
08:50 < stipa> docl: where are the mirrors, all around the glass sphere?
08:50 < muurkha> I mean, you have much more light pressure pushing the fuel apart
08:53 < muurkha> the idea that doing it in space is easier is interesting and plausible
08:56 < docl> OK let's switch to a more idealized context. you have a simple all-reflective sphere. It is 100km in diameter. At the center is rarified hydrogen. You throw some electrons at it and it starts to fuse. What happens next? One consequence is flinging protons outward. However, there are also photons. These move randomly, but mostly impact the sphere at an angle that directs them closer to the center. On 
08:56 < docl> the way, if they interact with the protons/electrons, they cause it to lose outward velocity or gain inward velocity.
08:59 < docl> The plasma (actually probably neutral, not just protons -- charge is another can of worms) do reach the sphere at high speeds, but very few of them per unit of area. If the fusion zone is 1m across, there is a 100,000:1 change in the area
08:59 < muurkha> calculations
09:01 < muurkha> sounds like you want to do them on IRC?
09:01 < muurkha> not interested
09:01 < stipa> sounds like a tax sinkhole in space
09:02 < docl> I can do the calculation myself, just setting up context
09:02 < stipa> throw in some art
09:02 < stipa> i want to see it
09:03 < docl> ok, I might be able to do that. do we have a standard drawing tool around here?
09:04 < stipa> just do some mockup i can't imagine it, i see a reflective balloon from outside with plasma glowing inside that i can't see
09:05 < stipa> i don't know what the reflective surface is for, to reflect the light fro mthe sun?
09:06 < docl> no, it's to reflect in the light. From 100km away, 1m looks like a point source
09:10 < docl> ok this is probably the relevant law https://www.engineeringtoolbox.com/optical-distance-law-d_353.html
09:12 < stipa> so, you want to trap light in that sphere, like collect it and store it?
09:14 < docl> yes
09:15 < stipa> so, if the sphere collects a lot of light something happens?
09:15 < docl> it's more about maintaining something happening (fusion)
09:16 < stipa> well
09:16 < stipa> light is heat
09:17 < stipa> heat waves
09:17 < stipa> a lot of the heat would probably damage the outer shell of the sphere
09:18 < stipa> would probably expand
09:18 < stipa> and pop
09:20 < docl> yeah, you want the sphere not to be too hot. hence making it large so that the light that reaches it is at a lower intensity. it's inversely proportional to the square of the distance
09:21 < stipa> what about waves canceling each other out while bouncing inside of the sphere?
09:24 < docl> my understanding is they have to be set up carefully for that effect to happen much. we're still talking about a randomized distribution of frequencies and so on. I imagine some waves do cancel in the system by happenstance, but hard to see that being a dominating factor
09:25 < stipa> you could call that part of the system "loses"
09:25 < stipa> also, there's light speed
09:26 < docl> well, the energy is still there, canceled waves don't actually phase out of existence entirely, they just stop interacting for a bit. as i understand it
09:27 < muurkha> that isn't exactly how it works
09:27 < muurkha> but none of this is
09:28 < muurkha> light isn't heat, either
09:28 < docl> there are more accurate ways to phrase that, yes :)
09:29 < stipa> i got used to heat
09:29 < stipa> it's everywhere 
09:30 < stipa> since sun is the molten lava i see it as heat
09:30 < stipa> The sun is a big ball of gas and plasma
09:30 < docl> ok, but none of that particular heat can reach us through a vacuum. instead we sense its radient energy (light)
09:32 < stipa> https://youtu.be/oDi9aMLF66E
09:32 < Muaddib> [oDi9aMLF66E] Two Decades Later, We Know Why the Sun Is a Lava Lamp (5:14)
09:33 < docl> I mean, we do experience solar wind, but it's tiny. most of the energy we get is more like when you move your hand next to a hot stove. the part you can't see from the stove that turns into heat on your hand is inrared. the sun is hotter, so we also get visible and higher frequencies (which pack more energy per photon and are shorter waves)
09:37 < stipa> hard to tell
09:37 < stipa> science regarding sun is mostly just photos
09:37 < stipa> and videos
09:38 < docl> oh my old friend hank. I wish I didn't find his voice anoying. he's a good guy.
09:38 < muurkha> if you have two equal EM waves that are 180 degrees out of phase the sum is literally zero
09:38 < stipa> yeah
09:38 < muurkha> but in the directions where they're in phase the summed amplitude is twice the amplitude of one of them, and the power is thus 4x
09:38 < stipa> if the light waves bounce inside of a reflective sphere some of it will cancel 
09:39 < muurkha> no, that's wrong
09:39 < docl> does that mean you can delete energy from existence?
09:39 < docl> my understanding is that you can't, but I've been wrong before :)
09:39 < stipa> docl: no, it's mostly heat after the acnelation
09:40 < stipa> cancleation*
09:40 < muurkha> no, that's completely wrong
09:40 < muurkha> I mean, in a sense it's a valid way of explaining why light doesn't keep going through the mirror, but mostly it's just wrong
09:41 < muurkha> cw: video above is SciShow, do not watch
09:42 < muurkha> (if you have had the misfortune of being subjected to a SciShow video before, you know what I mean)
09:43 < stipa> what's wrong with that smart dude?
09:43 < muurkha> dude is probably fine
09:43 < docl> hank and I used to debate creationism on AIM. I was the creationist. he was probably the least insufferable evolutionist I knew at the tiem. fun times.
09:43 < muurkha> but the video is a dude talking to a camera intermixed with stock photos
09:44 < muurkha> like all SciShow videos
09:44 < stipa> https://www.youtube.com/watch?v=OnFodIGcL2s
09:44 < stipa> ^^ Interference of waves in a ripple tank
09:45 < muurkha> the explanation in the Feynman Lectures of how interference produces reflection, and how it respects reversibility and conservation of energy, is the most lucid that I've found
09:47 < muurkha> don't waste your time watching dudes talking to cameras or watching five-minute videos.  there is no royal road to optics
09:49 < stipa> it's all legit
09:49 < stipa> he understands the physics
09:49 < muurkha> yeah, I'm not criticizing the dude
09:50 < stipa> and can clearly teach the concepts of waves
09:50 < muurkha> who? SciShow?
09:50 < stipa> no, my last link
09:52 < muurkha> while this video does at least show actual video content, there are no equations in it, so it does not contain the concepts of waves
09:53 < muurkha> you would have to be an Euler-level genius to learn the concepts of waves from it, and even then it would be unlikely
09:53 < stipa> there's nothing more to it
09:53 < stipa> the dude told it all and it can be visually seen in action
09:54 < muurkha> there is a great deal more to it
09:55 < muurkha> interference of two point sources in 2-D is just the beginning
09:56 < stipa> ok, light waves are a bit more complex since they're magnetic
09:57 < stipa> but they do interfere, cancel and add upon each other like 2D ones do
09:57 < docl> here's a picture of two concentric circles, one much smaller than the other. https://magma.com/shared/EGR3ezgi7PW2zYh0nu9yJA
09:57 < muurkha> yes, true, stipa 
09:58 < muurkha> a big problem with IRC is that it strongly selects for reacting rather than thinking, for cached thoughts over original ones, and for interruptible people over those engrossed in deep work
09:58 < docl> the circumference of the big circle is higher than the circumference of the smaller one. ratio to the diameter is pi. but in 3D, the ratio to the diameter is a square law.
10:00 < docl> that is, with spheres, if you have a 100,000 meter diameter, the surface area of it will be 100,000 squared times as much as that of a 1 meter diameter sphere.
10:05 < stipa> muurkha: that's life
10:18 < docl> it's a better snr than twitter at least. anyway time to reread muurkha's questions and consider what questions this doesn't already answer. I don't think we need to rehash how concave/convex mirrors work here
10:20 < stipa> docl: is there like a simulation software you could try your idea with?
10:21 < docl> if there is, I haven't found it yet.
10:22 < stipa> despite the cancellation of waves, surfaces also absorb light https://www.engineeringtoolbox.com/solar-radiation-absorbed-materials-d_1568.html
10:22 < stipa> so, that's also a loss 
10:23 < docl> how so?
10:23 < stipa> waves get absorbed by surfaces
10:23 < stipa> some portion reflects
10:23 < stipa> some gets absorbed
10:23 < stipa> depends of the surface material
10:25 < stipa> even if you have a reflective surface some of the wave won't bounce back
10:25 < stipa> but will get absorbed by the reflective surface of the sphere
10:28 < stipa> all you could do really is to heat the black body you've mentioned and do something with that heat there
10:28 < docl> oh, you mean the sphere isn't realistically going to be purely reflective. that's a bit of a loss, sure. it is also going to heat up a bit from diffuse plasma hitting it. it's going to glow a bit. however, the sphere temperature can be vastly lower than fusion. blackbody is a 4th power law, so that's critical.
10:31 < docl> we aren't trying to reuse the energy infinitely, just control the rate at which it escapes to a reasonable level. this is a lot easier to do at relatively low temperatures.
10:44 < docl> what makes it work (in my mental simulation) is that the reflected component of the light is much denser closer to the center. It approaches the amount being radiated by the core. So the fusion matter is both radiating energy outward and receiving near equivalent radiation from the shell, which means the thrust inwards from this factor is near double what it otherwise would be. the inward pressure 
10:45 < docl> grows less intense as you get further out, so some of the ions do escape this layer of containment. but note that they radiate energy as they go, and end up cooler by the time they get there. there's also a doppler effect where the particles moving away from the core recieve less energetic photons from the core than they do from the shell, so the net thrust tends to be inward for faster moving 
10:45 < docl> particles.
10:47 < stipa> i don't really get the core expanding
10:47 < stipa> of what material it is?
10:48 < docl> there are several light elements that can release energy from fusion, but we can imagine it with hydrogen at this proof of concept stage
10:48 < stipa> at the beginning i guess it's a black body, what is happening with it while it grows to the point of sphere edge
10:49 < stipa> you would light up the hydrogen in the middle of the sphere as a start of reaction?
10:49 < docl> well, it's hot, so the particles interacting tend to accelerate away from each other, which usually means outward. hot gas expands, in other words.
10:51 < stipa> but, if you want to expand more you would have to add more hydrogen, right?
10:51 < stipa> i guess from the centre
10:52 < docl> no, we don't want it to expand. we want it to stay small. but it has to be hot to fuse, so we need it to be forced towards the center to a greater extent than it wants to expand.
10:53 < stipa> hmmm, so you're collecting heat from the sun to make that reaction?
10:54 < stipa> do you know how much heat you need?
10:55 < docl> no, it's a fusion reaction so it releases heat whenever the hydrogen nuclei convert to helium or something heavier. you could use solar for ignition, and I've thought about feeding solar energy, but it's not a necesary component in this context.
10:58 < stipa> chemistry isn't my strong side
10:58 < stipa> that's where i'm leaving
10:58 < docl> why not learn chemistry?
10:58 < stipa> no time rn
10:59 < stipa> i should find an excuse
10:59 < stipa> rn i'm trying to endulge into DSP
10:59 < stipa> indulge*
10:59 < docl> well this is nuclear physics, so chemistry is a basic prereq :P
11:00 < docl> dyson sphere program?
11:00 < stipa> audio stuff
11:00 < stipa> i'll earn some C++ on the way, could come in handy
11:01 < docl> ahh. nice :)
11:01 < stipa> after that maybe chemistry
11:01 < stipa> probably sooner
11:02 < stipa> i'll have some contact with heavy electronics and mechanics soon
11:02 < docl> well, hydrogen and helium are the ones that stick up from the periodic table like ears. has to do with the first shell being 2 electrons
11:02 < stipa> there's battery stuff, there's soem chemistry
11:03 < docl> it all interconnects. hit me up with newb questions when you get to it
11:03 < stipa> ok, no problem, thanks for the offer
11:06 < docl> this is a good link once you have a certain amount of background to appreciate it https://ptable.com/
11:06 < muurkha> stipa: what is this nonsense about "no time"?  surely in the two and a half hours you have spent discussing thermodynamics in here, you could have worked through five or six intro chem exercises
11:06 < stipa> docl: a yeah, interactive table looks nice
11:08 < muurkha> an intro chem course is normally about 40 classroom hours and 100 hours of exercises, so you'd be 2% of the way to completing chemistry 101
11:08 < stipa> muurkha: i'm already behind the schedule 
11:09 < stipa> the thing i waste most of my time is IRC really
11:10 < muurkha> me too
11:11 < stipa> maybe if i delete it i'll become a better chemist
11:11 < docl> I waste time on twitter, irc, royal road litrpgs, video games, and somehow have a day job and a 2 year old kid and keep asking myself why I don't get more done...
11:12 < docl> just signed back up for college for the 5th time
11:15 < stipa> ppl are never satisfied with what they have and want more
11:15 < stipa> it's normal
11:15 < docl> one of those times was when I moved in with dani eder and signed up at the closest community college in his area and took gen chem. one class, so I could focus. two semesters. it was life changing.
11:17 < stipa> cool story
11:18 < stipa> do you do any fragrances ?
11:18 < docl> no?
11:19 < stipa> there's dude around, his connection to chemistry is fragrances 
11:19 < stipa> i guess
11:19 < stipa> a hobby of his
11:19 < docl> aromatic hydrocarbons? I've barely skimmed the surface, but apparently stuff with benzene rings tends to be smelly
11:20 < stipa> right, synthetic fragrances
11:20 < muurkha> lots of organic perfumes aren't aromatic in that sense
11:21 < docl> well, I didn't think they were all like that :)
11:21 < muurkha> see https://en.wikipedia.org/wiki/Aroma_compound#Aroma_compounds_classified_by_structure
11:21 < docl> still, I imagine it's a plot hook if you're already thinking along those lines
11:21 < docl> cool!
11:23 < muurkha> there's a nice table with the structures
11:25 < docl> they do all tend to be smaller molecules (since it has to actually reach the nose), so when you get to thinking about building blocks the familiarity will come in handy
11:26 < muurkha> what's surprising is the number of small molecules that have no smell, really
11:26 < stipa> dang, there's a rotting flesh molecule...
11:27 < stipa> Cadaverine
11:27 < stipa> has hydrogen
11:27 < docl> yeah, and putrescine

11:28 < docl> that whole table of amines is all unpleasant smells. makes sense given broken down nitrogenous things are going to be fertilizers
11:29 < muurkha> well, they're produced by bacteria digesting protein
11:30 < muurkha> which, in an ideal world, you would avoid getting on your hands, in your mouth, on your wounds, in your lungs,, etc.
11:31 < muurkha> by contrast, ferrous sulfate and diammonium phosphate have no smell
11:34 < stipa> Thioaceton...  
11:52 < docl> what have you learned so far about DSP? I haven't done a deep dive on that yet. got any cool applications in mind?
11:53 < stipa> i know some basics, i actually have to learn C++ to go further
11:53 < stipa> using this https://lv2plug.in/
11:54 < stipa> i have a goal but don't know how to get there yet
11:54 < hprmbridge> lachlan> What are you trying to do?
11:55 < stipa> first bessel crossover
11:55 < stipa> and a few usual things like compressors, that i'll probably copy from somewhere else
11:56 < stipa> multiband compressor with sidechains on each band made with bessel filters
11:56 < stipa> probably four
11:57 < stipa> four bands and four compressors in one unit
11:58 < stipa> it's an experiment, i want to get rid of ringing in filters
11:59 < stipa> bessel supposedly doesn't ring
11:59 < stipa> and signals are supposedly in phase when chopped
11:59 < stipa> and stitched back
12:00 < stipa> with a bit of penalty at the crossover point
12:00 < stipa> maybe 0.5 db or so dip
12:00 < stipa> i can live with that
12:03 < docl> is there a specific audio app you're hoping to improve?
12:03 < stipa> loudness war
12:04 < stipa> it should bring me closer to the 0dbfs
12:04 < stipa> now i'm at -0.5dbfs
12:04 < stipa> with the usual stuff on the market
12:05 < stipa> FIR filters ring about 0.5db
12:05 < stipa> at the cuttof
12:05 < stipa> at least in the low pass configuration
12:06 < stipa> and that clips
12:06 < stipa> 0.5db sooner than it should
12:06 < stipa> that ringing garbage clips the clipping point
12:06 < stipa> it's audible
12:07 < stipa> of course, that's a theory
12:08 < stipa> but i have no means to prove it, have to make my own test setup
12:08 < stipa> docl: but you can do whatever with the LV2
12:09 < stipa> but you're limited mostly to linux platform with LV2
12:09 < stipa> there is CLAP if you have other systems, it's free as LV2 is
12:10 < muurkha> C++ is not in any sense essential to DSP
12:11 < muurkha> can be handy tho
12:11 < docl> I use linux. sound setup tends to be kind of hairy if not preconfigured. multiple competing standards
12:12 < stipa> muurkha: yeah, in my case C++ is like very popular
12:12 < muurkha> not ringing comes at the expense of more phase error at the same width of transition region
12:12 < muurkha> I
12:12 < stipa> a dip in frequency spectrum where a crossover is i guess
12:12 < muurkha> 'd recommend trying your planned filters first in SciPy or Octave before putting them into C++
12:13 < stipa> docl: yeah, at some point it just starts to work
12:13 < stipa> pipewire is messy rn
12:14 < muurkha> you can very quickly try a lot of stuff out in SciPy in Jupyter or in Octave
12:14 < stipa> muurkha: i've tried easy ways
12:14 < muurkha> Octave is better if you don't know how to program, SciPy is better if you do
12:15 < muurkha> what are the easy ways you liked best?
12:15 < stipa> there won't be much math, i'll use a C++ library with filter in it
12:16 < stipa> https://github.com/vinniefalco/DSPFilters
12:17 < stipa> docl: you've got #lad
12:17 < stipa> linux audio dev
12:17 < stipa> all your needs are a question away there
12:19 < stipa> muurkha: no bessel filters
12:19 < stipa> that's the easy way
12:20 < stipa> and some filters sounded shitty, like 6db slopes instead of 24db and such things in such programs like matlab, etc.
12:21 < stipa> they're oke for getting into math of filters but i want a fast way in and out
12:22 < stipa> so, my matlab will actually be a professionally grade audio processor in DAW
12:22 < stipa> via C++
12:23 < docl> well I'm currently just letting popos automagically handle everything. uh, seems to be using pipewire
12:23 < stipa> yeah, distros are enforcing that crap on users
12:23 < stipa> i also has it
12:24 < docl> I guess it's fine if I don't have to touch it
12:25 < stipa> yeah
12:28 < docl> it would be nice if I could make it easier to listen to podcasts and such though. I tend to avoid audio content for the most part. part of it that earbuds don't work for my ears.
12:31 < stipa> get a headphones
12:32 < stipa> i have dt770 pro, but those are for home use not for outside
12:33 < docl> that also didn't work for me. I tried a few different ones. apparently there's an earwax buildup involved. I tried some drops for this, but they gave me earaches. still, solvable in principle.
12:33 < stipa> they go completely around my ears and ears don't touch the speaker cone protection inside
12:34 < stipa> you could get rid of ear wax with blasting your ear inside with slightly warm water
12:34 < stipa> via a bottle with extension on the top that fits in your ear
12:35 < stipa> eventually it should after few days go out if you have some
12:35 < stipa> especially if you've already waxed with drops
12:36 < docl> hmm. I had a lot of bad earaches when I was a child, maybe I'm just highly susceptible to them. blasting with warm water seems like the kind of thing that will trigger another one.
12:37 < stipa> well, that's how it goes out professionally too
12:37 < stipa> at the doctors place
12:39 < stipa> i got rid of most of that issues by cutting on industrial sugar
12:39 -!- cthlolo [~lorogue@77.33.23.154.dhcp.fibianet.dk] has quit [Read error: Connection reset by peer]
12:39 < stipa> i do blast my ears every day before tooth wash or whatever
12:40 < stipa> eventually you can do it by feel without damaging the ears or something
12:40 < docl> this is just using like a spray bottle, loaded with warm tap water?
12:41 < stipa> yea, luke warm tap water
12:41 < stipa> with a bottle that has extension you can stick in your ear canal
12:42 < stipa> doing that a few days should start blasting that shit out
12:42 < docl> I'll try it. I hate it when people say nothing works and then never try anything
12:42 < docl> got a link to what I should look for?
12:43 < docl> https://www.amazon.com/Removal-Cleaning-Disposable-Options-Straight/dp/B08PDCT31T say
12:44 < stipa> not sure if that can blast it with enough pressure
12:45 < stipa> that would just moist it slightly, you need a blast
12:45 < docl> I wouldn't have guessed earwax was a problem given I never have trouble hearing. it's just a low level irritation that gets worse if I try to use earbuds. I had some of the big headphones, but the moisture trapping effect seemed to be a problem.
12:46 < stipa> https://apotekos.com/wp-content/uploads/2020/04/Clinil-Etilni-Alkohol-70-.jpg
12:46 < stipa> see that top
12:46 < stipa> beneath it is like this /\
12:47 < stipa> you stick that top in your ear canal and squeeze the bottle
12:47 < stipa> the water will be under the pressure pushing wax out
12:49 < stipa> maybe not immediately but after a few day it'll go out for sure, you'll know when it happens
12:50 < stipa> you'll see the wax all over your bathroom sink
12:50 < docl> am anticipating pain. will try it though.
12:51 < stipa> yeah, when you see it fill the bottle one more time and go with it until there is no wax left in the ear canal
12:51 < docl> this syringe tip look reasonable? https://www.amazon.com/Healeved-Removal-Cleaning-Irrigation-Flushing/dp/B0B63FY52N
12:51 < stipa> and then do it regularly when you feel you should do it
12:51 < muurkha> do not do this with a literal bottle of denatured alcohol!
12:51 < stipa> yeah, not bad
12:52 < docl> well obvs
12:52 < stipa> the blasts will be short with those but better than the one before
12:52 < stipa> spray based
12:52 < docl> warm non saline water from the tap should be fine though?
12:52 < stipa> yeah
12:52 < stipa> like warm is the key to fuck up the wax
12:53 < stipa> it makes it liquid so to say
12:53  * muurkha fucks down the wax
12:54 < docl> makes sense. the drops I used last week were carbamide peroxide. seemed to liquify the wax, but then it would sit there and block my hearing
12:54 < stipa> wax is usually crusty inside
12:54 < stipa> dry
12:54 < docl> maybe it works better combined with a washing step
12:54 < stipa> right
12:55 < stipa> the combo should work best
12:55 < docl> ok, something to try. thanks :)
12:55 < stipa> np
13:01 < docl> the other factor that stops me from enjoying podcasts so much is sensitivity to voice quality. like, I want to hear what this guy has to say but do I really want to hear his voice for 2 hours? https://www.youtube.com/watch?v=YDjOS0VHEr4
13:03 < docl> seems like we need a way to swap out annoying nerd voices with James Earl Jones or something. Darth Vader describing self replicating robots wouldn't be so bad
13:05 < stipa> sounds like a tax sinkhole
13:05 < muurkha> that sounds achievable with off-the-shelf technology
13:05 < muurkha> like, Codec 2 and one of its newish WaveNet-derived neural network decoders
13:06 < stipa> seems like that dude want's to build stuff from molecules up
13:07 < stipa> replicators
13:07 < muurkha> there are also a lot of ANNs out there designed for deepfaking celeb voices already, typically using text input
13:12 < docl> yeah but is there a firefox plugin or something I can actually use yet?
13:13 < L29Ah> it takes less time to set it up than to theoretize on space fusion mirrors
13:14 < docl> suuure
13:16 < docl> even if that's true, fusion space mirrors sucessfully grabs my focus in a way producing a good voice substitution plugin doesn't.
13:18 < docl> I can't be the only person with this problem though. surely someone with the appropriate fascination exists out there, right?
13:19 < stipa> there's probably a friendly community

18:03 < fenn> speech2speech would be better than text2speech for deepfake stuff
18:03 < fenn> docl: earwax might be a symptom of omega-3 deficiency
18:06 < fenn> kanzure a start would be to give humans the bigbench word problems. this assumes the ability to read english, which is already pretty high up on the cognitive abilities scale
18:06 < fenn> https://github.com/google/BIG-bench
18:08 < fenn> there's a difference between innate cognitive ability and learned cognitive ability
18:08 < fenn> this benchmark suite doesn't really distinguish
18:11 < docl> I'll start supplementing omega-3. looks like I may have other symptoms of that as well. Thanks.
18:14 < fenn> you can get a refrigerated black bottle of lemony goop from whole foods, made by barleans. or if you are ok with spines and fishy smell, canned pink salmon is reasonable. it's hard to know if fish oil capsules are made from undamaged oils, since manufacturers go to great lengths to hide the fishy smell
18:17 < fenn> since the salmon is canned in an environment with limited oxygen, it can't have reacted with very much oxygen over time
18:17 < fenn> in contrast, fish oil capsules can sit on a hot shelf in an oxygen permeable plastic bottle for months
18:26 < jrayhawk> pastured eggs are also an easy surce
18:47 < muurkha> I've been eating mackerel on the theory that it has more fat than salmon

20:59 < kanzure> fenn: ok but isn't there supposed to be a whole field of intelligence psychometrics
21:06 < fenn> a long time ago the relevant researchers realized that all of their various tests and metrics correlated, so they gave up on measuring them individually and instead focused on designing better tests to measure the overall variability between humans
21:07 < kanzure> is human variability that interesting? even the rather dumb humans are still a few leaps ahead of canines.
21:09 < fenn> it's important to humans
