00:24 < nmz787> well that *only* took me like, an hour or something stupid

01:32 < mrdata> nmz787, you will have to organize your place; look at everything and rationalize it. do you need it? where should it belong? what goes with it? etc
01:33 < mrdata> so that the next time you need it, you can go directly to it
01:36 < nmz787> mrdata: organization is probably my biggest downfall.... neither of my parents were very good at it
01:36 < nmz787> and unfortunately, I have so many projects, and my projects are so lengthy/in-depth that I have lots of parts and lots of tools
01:36 < maaku> If I was good at organizing physical things, I wouldn't be in software.
01:36 < nmz787> grep is pretty amazing for finding stuff
01:37 < mrdata> my father was so good at it, it was scary
01:37 < nmz787> does anyone here remember this? https://www.ebay.com/itm/Vintage-Tyco-RC-Super-Rebound-4x4-RC-Car-49-MHz-Complete-w-Instructions-NO-BOX/324043659158
01:37 < nmz787> https://www.youtube.com/watch?v=3qM0UWNqxkw
01:37 < mrdata> grep however is slow at seaqrching whole filesystems
01:37 < nmz787> "only TYCO rebound does IN YOUR FACE FLIPS!"
01:39 < nmz787> mrdata: luckily I usually only need to grep my user dir, or a backup harddrive
01:40 < mrdata> this was a solved problem for awhile,
01:41 < mrdata> there was this command called agrep
01:41 < mrdata> but the authors did not anticipate having it run on the huge filesystems we have today, or they would have widened some of the indexes
01:42 < mrdata> it was neat tho. indexes were < 10% of the file space
01:42 < mrdata> and astonishingly fast
01:43 < jrayhawk> i throw xapian at most things
01:44 < jrayhawk> its relevance scoring system is kinda slow on anything but a unified index, though

04:15 < archels> they moved their patients to an undisclosed location recently
04:16 < nsh> how can biohackers help in the case of something like this coronavius outbreak?
04:16 < nsh> is there any hard-to-automated drudgework that can assist with finding/formulating vaccines or something?
04:17 < nsh> i guess it's difficult without access to samples and secure lab environments
04:17 < nsh> prototype some cheap antiviral facemasks maybe
04:19 < nsh> 26-32kilobases, can't be that hard to hack
04:19 < nsh> you can barely implement snake in 32kb
04:20 < nsh> (this is a lie, you can do it in a tenth of that, but that's not the point)
04:21 < nsh> i suppose virii have access to a rather comprehensive API of libraries
04:21 < archels> nature's virtual machine has a richer instruction set though

14:22 < fenn> "the ongoing shortage of donor sperm in the UK, argue the authors, which has led to Britain importing commercially donated sperm to cope with demand from couples struggling to conceive"
14:22 < fenn> how
14:22 < fenn> how are there not enough horny young men in the UK willing to donate?
14:23 < fenn> is there something special about the UK in this regard?
14:24 < fenn> nsh it's time to do your solemn duty
14:25 < fenn> earth needs your finnish genes
14:30 < kanzure> probably not enough *qualified* people
14:34 < kanzure> good education, good career, good sperm count...
14:35 < fenn> HFEA website says they also need sperm for research and IVF technician training
14:35 < kanzure> do it for the queen
14:36 < fenn> just hold her image in your mind
14:36 < fenn> hold it for as long as you can, and then release
14:37 < fenn> so it's no longer possible to donate anonymously in the UK
14:38 < fenn> "providing you donate through a licensed UK fertility clinic, you will have no legal rights or responsibilities to children conceived from your donation. You'll have no say over their upbringing and won't be required to pay anything towards their care. 
14:38 < fenn> If you donate outside of a licensed clinic, the situation is more complicated as you could be considered the legal father of any children conceived from your donation."
14:49 -!- jessica__ [~jessica@ool-18ba13b4.dyn.optonline.net] has joined ##hplusroadmap
14:49 < fenn> i wonder how they handle rules around anonymity for commercially imported sperm
14:49 < fenn> like if one country says you must be anonymous then are they just unable to import from them at all?
14:50 < fenn> or are foreign donors not subject to UK laws
14:50 < fenn> i mean technically it's just a tissue sample right?
14:52 < jessica__> what do you mean it's only a tissue sample?
14:54 < fenn> it's not like a legal person went to the UK to donate; they didn't necessarily have anything to do with what happened to the donation after they visited a clinic in their own country
14:54 < fenn> by "legal person" i mean some entity that counts as a person according to a legal system
14:55 < fenn> we are discussing the shortage of sperm in the UK supposedly necessitating this: https://kvia.com/health/2020/01/21/men-should-be-allowed-to-donate-sperm-after-death-study-says/  https://jme.bmj.com/content/early/2020/01/08/medethics-2019-105637
15:01 < fenn> jeez there were only 237 sperm donors in 2004
15:01 < jessica__> that's what I thought you were talking about.I would think if a country has laws against anonymity, imported anonymous donations would probably be unusable. Just speculating though
15:02 < fenn> well there's two ways to go about it, within the HFEA system or DIY
15:03 < fenn> there may be a different set of rules that applies when you do it in the system, compared to using websites like https://spermdonationuk.co.uk

15:09 < jessica__> I would think websites like the one you linked are subject to the same laws
15:09 < jessica__> what do you mean by DIY
15:09 < kanzure> not through a UK fertility clinic.
15:10 < fenn> i don't really know anything about it. this is the first i've heard of it really, as i assumed people mostly went through fertility clinics
15:10 < fenn> but apparently some people avoid clinics because of cost or some other weird thing like "co parenting" whatever that means
15:11 < fenn> or some other reason, i don't really know yet
15:12 < jessica__> yeah I would think anyone going outside of the clinic or similar institution is heading into the "black market" territory
15:13 < jessica__> & some donors opt for co-parenting so they are still a part of the child's life and have a role in decisions. I can see why some people wouldn't like that

19:41 < lsneff> It's a microlens array light-field display
19:48 < nmz787> seems a little ugly of a rendered image
19:49 < lsneff> The resolution is only 160 * 104
19:50 < lsneff> Actually high-resolution microlens displays would require very high resolution underlying displays
19:50 < lsneff> 2-3 times higher than 8k
20:02 < jrayhawk> which is becoming increasingly plausible, these days.
20:04 < jrayhawk> what would be really deeply impressive is combining that with a very nice light-field camera to get visually immersive AR

20:07 < lsneff> Mobile gpus, and gpus in general, need to get faster to render for these since it probably requires raytracing.
20:08 < lsneff> I don't seriously think we'll see a 23040 x 12960 display anytime soon.
20:09 < lsneff> and that's for pretty few distinct viewing angles
20:14 < jrayhawk> i don't understand, how is raytracing relevant to microlense rendering?
20:15 < lsneff> I could be wrong, but I think you need to render whatever you're showing on the screen from every possible point of view, so you raytrace from every virtual camera
20:16 < lsneff> Maybe you can just render it normally, but you would have to render it many times

20:18 < lsneff> You still do have to render each frame like 100+ times for each point of view
20:26 < jrayhawk> Sony/Toshiba/Hitachi claim to have a 17.3" 7680x4320 panel, but god only knows what sort of microwire concentration you'd have to power through with that sucker
20:27 < jrayhawk> there are some prototypes at 8.3 inches
20:29 < lsneff> The paper on that holoflex device claims that it needs to render the scene separately for each microlens in the array.
20:30 < lsneff> So, in that example, 16,640 times.
20:30 < jrayhawk> the 8.3 one is OLED-based, so that'd actually be reasonably power efficient

20:38 < lsneff> Looking glass looks cool. Why is there a thick layer of plastic above the display though? Can't the lenticular filters be pretty thin?

22:03 < nmz787> seems like you could have a collection or like 5 or 10 OLEDS, and feed them a signal, then a local circuit wobbles that signal left/right and up/down... projecting into the microlens array for that combo "pixel"
22:03 < nmz787> idk, just thinking of how to reduce the complexity of rendering, using existing 2D images, and reduce fanout wire density
22:11 < fenn> additional liquid crystal layer to mask out the subpixels not in use in that subframe, and persistence of vision to blur it all together. then you just need num_subpixels times the framerate
22:12 < fenn> of course it will also use num_subpixels times the power and have crappy contrast ratio
22:13 < fenn> it's too bad kerr cells are explosive and high voltage
22:18 < fenn> it would probably be easier to do this with something like a MEMS DMD array
22:20 < fenn> each mirror would dwell at each angle for a period of time corresponding to that angle's brightness for that pixel
22:31 < maaku> what's the goal? glasses-free 3D display?
22:33 < jrayhawk> http://www.google.com/search?q=spinning+mirror+light+field&tbm=vid there are some spinning mirror light field systems
22:33 < maaku> the easiest method (for one viewer only) is to put a high resolution front facing camera with a depth channel, and do eye tracking
22:34 < maaku> if you know (or can configure) the interocular distance, you could do this with a standard laptop webcam
22:35 < maaku> it's on my todo list list to try sometime

22:57 < jrayhawk> the goal i care about is getting around problems with augmented reality related to mixed content focus/depth-of-field and the horribly offset HMD camera systems we have now.
22:57 < jrayhawk> https://www.youtube.com/watch?v=FA1vPWGcokE Mixed reality is probably a more tractable approach, though.
