05:03 < streety> drethelin: Their product seems to be at http://www.elysiumhealth.com/basis My initial impression is that the marketing is heavy and light on facts. For example, knowing the quantities of the active ingredients should be easier than it is. Based on that I was expecting their prices to be some multiple of competitors for the same compounds but that doesn't appear to be the case.
05:03 < streety> for example http://www.lifeextension.com/Vitamins-Supplements/item02031/Optimized-Resveratrol-with-Nicotinamide-Riboside#panelSupplements would work out to be roughly the same price

07:40 < JayDugger> Mornng, catern. I am happy to hear of your success. Remember to find a good way to catalog all the recordings you accumulate.
07:42 < JayDugger> Spider monk, spider monk. Does what ever a monk can do. Proofs a book, any size. Catches typos, just like flies. Look out! Here comes the spider monk.
07:44 < kanzure> you forgot about his vow of silence
07:44 < JayDugger> Heh.

08:57 < JayDugger> No, he ended up cremated and shot into space in 1997 with Rodenberry and O'Neill by Celestia.

10:05 < maaku> catern: I'll send them an email as well
10:05 < maaku> maybe if they get more than one inquiry about this they might be more helpful...
10:05 < catern> actually, it looks like there are a lot of products dedicated to this purpose
10:05 < maaku> there's a fucking huge opportunity here
10:05 < catern> http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Delectronics&field-keywords=watch+voice+recorder
10:06 < kanzure> hm a wristband..
10:06 < maaku> incidentally someone mentioned the cocktail party problem in the scrollback. solution is to put one on each wrist
10:07 < maaku> ideally i'd have a smartwatch on one wrist, and a high quality mic (kapture?) on the other
10:07 < kanzure> er, my expectation was that the solution would be putting microphones in each ceiling tile
10:08 < maaku> kanzure: for a conference, yes, but I'm talking about a mobile record-everything-everywhere-i-go solution
10:09 < catern> hmm
10:09 < catern> i don't know anything about audio capture
10:09 < maaku> i want something looking like a IRC chat log - date, time, nick (voice identification), text (transcribed), and a little play button to hear the original audio
10:09 < catern> is it possible to reconstruct a high-quality audio stream from the the two recording wristbands
10:11 < catern> is there some off-the-shelf software I can use do that
10:11 < catern> i literally don't know
10:11 < maaku> catern: sure, that's essentially what high quality microphones do internally. they have multiple mics for noise cancellation and dopler isolation
10:11 < maaku> there's plenty of software.
10:12 < catern> so you assert, but do you know of a specific example?
10:12 < maaku> but what'd be unique and require something custom is that the mics (your wrists) would be in presumed constant motion, both absolutely and relative to each other

10:14 < maaku> catern: because it's literally an entry-level DSP problem, e.g. something that's assigned as homework for a signal processing 101 class
10:14 < kanzure> nah just throw in some accelerometers and uh.. something..
10:14 < catern> maaku: oh, ok

10:14 < maaku> catern: as to the question "which software should I use", idk
10:15 < catern> yeah, i get it now
10:15 < maaku> kanzure: good point the accelerometer (which is already in the smartphone anyway) should make the problem easier
10:15 -!- sivoais [~zaki@unaffiliated/sivoais] has joined ##hplusroadmap
10:16 < catern> but you don't have an accelerometer in these voice recording watches I assume

10:21 < catern> that is similar to how i feel. but before I couldn't think of decent hardware for this
10:22 < catern> but the belt-clip-phone would work great
10:22 < maaku> I have a personal problem that while I'm highly organized at work with a system to keep track of commitments, it's hard to keep that up at home.. I'd love to be able to quickly review the conversation with my wife to remember what I promised to do, or pull up the chat I had with the teacher or school counselor
10:23 -!- nmz787_i [~ntmccork@134.134.139.82] has joined ##hplusroadmap
10:24 < catern> indeed
10:31 < catern> hmm
10:33 < catern> if someone has a smartwatch on their wrist (good quality), and a smartphone in their pocket (poor quality), i wonder if you could use both of them with enough DSP magic and get a clear enough signal out to feed into machine learning
10:34 < catern> so you could maybe do this without any special hardware/behavior changes
10:35 < catern> oh! and phones have multiple microphones, too

10:43 < maaku> catern: sent
10:44 < maaku> hopefully I can get a better response from them
10:45 < maaku> catern: that's the idea .. the larger the separation in space, the better
10:46 < maaku> sound moves about 7mm/sample at 44.1kHz
10:47 < maaku> so a wristband and pocket phone should be 10's of cm apart, which would be enough to do doppler isolation which not only separates voice samples, but also eliminates background noise
10:47 < maaku> that'd probably do more to improve quality than any kind of reconstruction combining the sources
10:49 < kanzure> 35106 conversations, 182424 tags, 33600 unique tags
10:49 < maaku> so I was imagining sampling both sound feeds on the phone, doing doppler analysis to separate sources and drop line noise, then uploading the separate, compressed feeds for further processing
10:50 < maaku> the biggest optimization is just detecting when nothing interesting is going on, because otherwise you have 500MB/day of audio ;)
10:52 < catern> 500MB a day = 182.5GB a year
10:52 < catern> practically nothing
10:53 < maaku> catern: not nothing when you're pushing it through you 4G LTE metered plan ;)

10:53 < catern> sure, that's why you only push it out on wifi
10:54 < cluckj> check on the legality of it too before you start recording everyone :)
10:54 < catern> everyone has the right to perfect memory, cluckj

13:50 < nmz787_i> yeah I think so... since they're like harmnoics or something
13:50 < nmz787_i> i know some spectrometers collect multiple orders and add/average them to increase SnR
13:53 < chris_99> ta, see i was confused, how you'd end up with both 100nm @ 9th order, and 900nm @ 1st order, in the same position
13:53 < chris_99> how you'd distinguish between them
13:54 < chris_99> but i guess the 900nm would just have the highest amplitude
13:58 -!- jaboja [~jaboja@vps.jaboja.pl] has joined ##hplusroadmap
14:05 < nmz787_i> well I think if they overlapped then you're screwed
14:07 < chris_99> but say 100nm @ 9th order, and 900nm @ 1st order:  arcsin((1 * 900e-9) / 2e-6))  and arcsin((9 * 100e-9) / 2e-6)) both give the same radians, so theoretically i guess they could end up in the same position

14:09 < maaku> http://kapturelive.com/klip/553cf203e13b4c3b03dae6e3 (inside a vehicle)
14:09 < maaku> http://kapturelive.com/klip/559c5884e13b4c0c446fef02 (pretty cute)
14:09 < maaku> http://kapturelive.com/klip/55cbf255e13b4c026227f25d (funny)
14:11 < nmz787_i> chris_99: yeah they definitely can end up like that, I'm just saying you would have to have a good reason to /want/ them to overlap... separating the signal strength of each individual frequency would probably involve some assumptions about your signal source or something
14:11 < maaku> catern: he did point me at this though : http://sasquatchbioacoustic.blogspot.com/2016/01/long-duration-recorder-ldr-based-on.html
14:11 < xentrac_> nmz787_i: yes, I'm in Buenos Aires!
14:11 < chris_99> nmz787_i, oh i don't want them to overlap, i'm just confused what happens when they do
14:12 < nmz787_i> it would just be like shining a red and a purple laser on the same spot
14:12 < nmz787_i> colors would mix apparently to our eyes
14:13 < chris_99> mmm, theres not much you can do then i guess if they do
14:13 < chris_99> so you could get incorrect results i guess
14:21 < nmz787_i> reseparate would be possible
14:22 < nmz787_i> xentrac_: ever been to Columbia?
14:22 < nmz787_i> Colombia*
14:30 < xentrac_> no, when my then-wife and I were trying to figure out where to live, we figured Colombia was too scary for our families to want to visit
14:47 < chris_99> http://www.symmetrymagazine.org/article/lhc-data-at-your-fingertips that's really cool

14:51 < maaku> catern: I think I'm getting ahead of myself. step 1 is just to setup a background 'record everything' app

14:51 < catern> oho, interesting
14:52 < catern> of course in-ear bluetooth should work

17:12 < fenn> hmm it may be illegal in california to save your emails without informing all parties to the email
17:14 < fenn> so i'd want to have a fixed array of microphones with raw uncompressed recording of each one, then dump all that data each night for offline processing, where you do source separation and noise reduction, then compress each source individually along with metadata about its location and amplitude
17:15 < fenn> this can then be reconstructed as a 3d audio scene which you can fly around in or simply follow the original path of the microphone array
17:16 < fenn> i think having a non-fixed baseline like one microphone on each wrist is just making things difficult for yourself
17:17 < fenn> on the other hand it does give you a little bit more parallax to triangulate relatively constant noise sources, because you are moving around more and thus providing more information about the noise
17:50 < maaku> fenn: that's where I'm headed, except I don't expect the array to be fixed (e.g. wristbands, phone in pocket that sometimes gets taken out; relative positions will change)
17:51 < maaku> but it seems like recording the audio to the phone only doing detection of dead sound (no voices), and bulk uploading when you get wifi is best
17:51 < maaku> fenn: the goal (for me) is to capture conversations throughout my life, not just in a conference setting
17:51 < maaku> so fixed mic arrays isn't really practical
17:54 < maaku> I emailed kaptureaudio again to see if I can get a datasheet/low level API just for my own personal use

19:22 < fenn> by "fixed array" i just mean multiple microphones on a single device
19:23 < fenn> like a phone with 16 microphones or whatever
19:23 < maaku> fenn: I think there is significant benefit to be had from having large separations between the mics to do doppler separation
19:24 < fenn> i don't know what doppler separation is; but yes a larger baseline is better
19:24 < maaku> sound moves about 7mm per sample at sea level for 44.1kHz
19:24 < maaku> fenn: cocktail party problem
19:25 < maaku> https://en.wikipedia.org/wiki/Cocktail_party_effect
19:25 < fenn> is doppler separation similar to how those gunshot detection algorithms work? simple trilateration?
19:25 < maaku> I've heard it called doppler separation, althoug I'm not really sure why
19:26 < fenn> the wikipedia article is about attention and biological stuff
19:26 < maaku> oh sorry https://en.wikipedia.org/wiki/Source_separation
19:27 < fenn> so are you saying doppler separation = source separation?
19:27 < maaku> yes i've heard both terms
19:28 < maaku> there's many ways to do it. e.g. you can use the fact that sound arrives at different times at different positions, or that sound drops off at 1/r^2, or echo delays indoors
19:29 < fenn> i'm seeing a paper about monitoring train bearings by "doppler separation" but this is a special case where the different train cars have different relative velocities wrt the microphone
19:29 < fenn> so each bearing will have an individual frequency shift
19:31 < fenn> i keep trying to learn how kalman filters work but it never seems to stick

19:55 < kanzure> "PanSTARRS' imaging survey will make 2 PB available online"
19:56 < kanzure> "You [can] buy a 180TB 4U backblaze storage pod assembled for about $10,500. For $21,000 you can buy two and have 60TB to spare. $8,500/ $17,000 if you want to DIY."
19:56 < kanzure> ( http://www.backuppods.com/ )
20:45 < xentrac_> fenn: I have the impression that kalman filters are actually a straightforward application of Bayes' theorem
20:46 < xentrac_> under the assumption that the probability distribution of the thing you're trying to determine is a multidimensional Gaussian
20:48 -!- ArturSha1 [~ArturShai@212.97.31.129] has joined ##hplusroadmap
20:48 < xentrac_> apparently if both your prior and the conditional probability you're using to update it are Gaussians then the posterior probability is also a multidimensional Gaussian?
20:48 < xentrac_> or maybe it isn't and you just pretend that it is, I don't remember
20:49 < xentrac_> but I think that's enough of the idea to derive Kalman filtering from
20:50 < xentrac_> I think that Kalman filtering may not be a great fit for audio source localization though
20:51 < xentrac_> but maybe that was a potentially unrelated comment
20:52 < xentrac_> nmz787_i: I am sure that you can use a zeolite dehumidifier to get water in the desert
20:56 < xentrac_> I mean you have to use hot air to get the water out of the zeolite, and hot air will keep getting water out of the zeolite until it's saturated
20:58 < xentrac_> which is to say that its dewpoint is the temperature of the hot air
21:00 < nmz787_i> yeah I use it in my garage now
21:01 < nmz787_i> it works pretty good, constant dehumidification across temperatures, though the data they provide stops around 90F
21:01 < nmz787_i> (it works great at i.e. 0C where a refrigerant based wouldn't be able to)
21:02 < nmz787_i> (or at least not very well)
21:12 < xentrac_> yeah, I think you can make frost refrigeratively, but I'm sure the process slows quite a bit as the frost begins to insulate your refrigerant coils
21:12 < xentrac_> I mean I'm quite sure you can; I've done it

21:32 < nmz787> that it crashes and isn't reliable, and then try brlcad
