09:18 < delinquentme> so is there some reason that on the same machine I need to enable CORS to run API POSTs??
09:18 < chris_99> this is amazing http://googleprojectzero.blogspot.de/2015/03/exploiting-dram-rowhammer-bug-to-gain.html
09:21 < kanzure> delinquentme: well are you requesting from a different origin?
09:23 < delinquentme> kanzure, no I don't think so im making an API call from within the console of chrome
09:23 < delinquentme> is that a different origin?
09:26 < kanzure> and what is the destination host
09:27 < kanzure> i mean the hostname
09:27 < heath> delinquentme: are you using the same port as the page is served on?
09:28 < delinquentme> I am. 5000
09:28 < delinquentme> localhost
09:28 < heath> shouldn't need it then
09:31 < delinquentme> because this: curl -H "Content-Type: application/json" -d '{"project":"MCE"}' -X POST http://localhost:5000/runmodel
09:31 < delinquentme> work as expected
09:32 < delinquentme> POST http://localhost:5000/runmodel
09:32 < delinquentme> graph_proto.html:1 XMLHttpRequest cannot load http://localhost:5000/runmodel. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 400.

09:59 < delinquentme>  It seems that default flask-restful has class methods pertaining to the verbs ( POST, GET,... )  but then some of these frameworks are thrown on top ... and the happen to break the pattern of defining the verbs as resource class methods, and instead define it as a method to something else .... @app.route("/", methods=['GET'])
09:59 < delinquentme> IDK just some curious behavior
10:02 < kanzure> you should prefer flask-restless
10:05 < delinquentme> kanzure, how does it work that all of these near substitute codebases ... all have a similar HTML / design layout

10:22 < delinquentme> nmz787_i, i saw the post about intel !
10:22 < chris_99> nmz787_i, did you ever get that teeny tiny laser engraver?

10:28 < heath> 09:39 < delinquentme> Chrome does not support localhost for CORS requests (an open bug since 2010).
10:28 < heath> ah, i knew there was a reason i never bothered doing anything but CORS
10:29 < delinquentme> firefox the same
10:29 < delinquentme> I mad a rather inflammatory post in #firefox
10:29 < heath> safari?
10:29 < delinquentme> <delinquentme> $.post( "http://localhost:5000/runmodel", function( data ) { console.log( data ); }); Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:5000/runmodel. This can be fixed by moving the resource to the same domain or enabling CORS.
10:29 < delinquentme> <delinquentme> TIL localhost is not same-domain
10:29 < delinquentme> heath, no have
10:29 < heath> uzbl?
10:29 < delinquentme> heath, where the fuz is my hug back ?

10:30 < heath> see PM in the future
10:30 < heath> i keep PDA private

10:38 < heath> so much stuff to see, but i think i might just restrict myself to checking out biocuruious and noisebridge
10:38 < heath> might just stick with biocurious
10:40 < heath> it would be nice to visit transcriptic for funzies as well
10:41 < delinquentme> heath, counter culture labs + berkeley bio labs
10:41 < delinquentme> also indie bio
10:41 < delinquentme> theres shitloads of accelerators
10:41 < delinquentme> but the places you want to be *arent* the accelerators
10:41 < delinquentme> go to actual labs :D
10:41 < delinquentme> like where Im headed tomorrow
10:42 < heath> delinquentme: cool, maybe you can show me around :) i'll pay for the uber or whatever
10:43 < delinquentme> you're not getting the SF experience unless you're licking handrails on the bart
10:43 < delinquentme> heath send me info about you or add me on fb
10:47 < delinquentme> firefox policy:
10:47 < delinquentme> In Gecko 1.8 or earlier, any two file: URIs are considered to be same-origin.  In other words, any HTML file on your local disk can read any other file on your local disk.
10:47 < delinquentme> Starting in Gecko 1.9, files are allowed to read only certain other files.  Specifically, a file can read another file only if the parent directory of the originating file is an ancestor directory of the target file. Directories cannot be loaded this way, however.
10:47 < delinquentme> https://developer.mozilla.org/en-US/docs/Same-origin_policy_for_file:_URIs
10:48 < delinquentme> TLDR: Gecko 1.8 file to file was considered same-domain.... Gecko 1.9 CORS is required for anything in a different directory
10:51 < delinquentme> nmz787_i,
10:51 < delinquentme> the only thing though is that application, if defining CORS within the flask application ... is using flasks internal server ( whatever it is ) as a production server

11:51 < kanzure> delinquentme: use celery
11:51 < nmz787_i> i think chrome generally hates on long AJAX requests... but if you worry about recovering after a broken/failed connection then AJAX prob wouldn't work
11:51 < nmz787_i> yeah that sounds reasonable
11:52 < delinquentme> kanzure, I thought celery would be running on the task-master node
11:52 < nmz787_i> something the job-starter could ping and ask "hey is that job done" or "hey when that job finishes, contact me at..."
11:52 < delinquentme> so you're saying that celery is handling the communication between processing node and the task master ... celery doesn't handle the instantiation of the machine though right?
11:52 < delinquentme> thats integration w your infrastructure code
11:55 < delinquentme> right now I had imagined the infrastructure being a processing server running nginx and the computationally heavy models we're running
11:55 < delinquentme> and the user front-end server simply making API calls to that
11:55 < kanzure> celery does not do machine instantiation by default, but you could write a task that does so
11:56 < kanzure> celery handles task queues, including insertion into those queues

13:26 < nmz787_i> fenn: so you're saying the time is too small, such that the camera likely will blur the photons into the same depth bin most likely?
13:26 < nmz787_i> yeah but that trillion fps was with pulsed light
13:26 < nmz787_i> seems like you'd need pulsed light plus something to slow the photons down
13:26 < nmz787_i> so the slow camera could register
13:27 < nmz787_i> well, they're doing pulsed light plus phase shift of capture time
13:27 < archels> just dropped in to this conversion, but was reading about time-of-flight analysis for PET earlier, and they can only get the uncertainty down to ~10 cm or so
13:27 < archels> found that pretty disappointing
13:30 < fenn> lemme just whip out my time warp field generator...
13:30 < fenn> PET photons have unknown phase
13:30 < fenn> the wavelength is too short to compare phase anyway
13:31 < archels> chris_99: cute displays
13:32 < fenn> nmz787_i: maybe you could make something like a time prism out of a kerr cell... photons go in and come out at an angle that varies with time (over a few picoseconds)
13:32 < nmz787_i> I'm going to give the real sense camera a try anyway, someone has one locally.... it looks like it might use some sort of frequency based encoding to get depth data, so the time of flight get's mixed into the frequency component of the image to be extracted later with processing... so who knows, maybe something cool will happen
13:33 < fenn> .wik kerr cell
13:33 < yoleaux> "The Kerr effect, also called the quadratic electro-optic effect (QEO effect), is a change in the refractive index of a material in response to an applied electric field." — http://en.wikipedia.org/wiki/Kerr_cell
13:33 < nmz787_i> so LCD maybe
13:33 < nmz787_i> or something
13:33 < chris_99> archels, i've emailed a UK company that sells the chemicals in kits
13:33 < chris_99> to make them
13:33 < nmz787_i> that would probably change the polarization
13:33 < fenn> that's useless
13:34 < nmz787_i> (for this application)
13:34 < fenn> isn't "real sense" just random dot projection?
13:34 < fenn> .wik real sense camera
13:35 < yoleaux> "" — http://en.wikipedia.org/wiki/SixthSense
13:35 < fenn> hmm
13:35 < fenn> .wik realsense camera
13:35 < yoleaux> "Wikipedia:Featured picture candidates/Aldrin saluting American Flag" — http://en.wikipedia.org/wiki/Wikipedia:Featured_picture_candidates/Aldrin_saluting_American_Flag
13:36 < nmz787_i> yeah either 'random' or some known pattern that is unique enough to use for encoding and decoding
13:36 < nmz787_i> .wik structured light
13:36 < yoleaux> "Structured light is the process of projecting a known pattern of pixels (often grids or horizontal bars) on to a scene. The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners." — http://en.wikipedia.org/wiki/Structured_light
13:36 < nmz787_i> that doesn't do what I'm talking about justic
13:37 < fenn> ok but "structured light" usually involves projecting an entire basis set, like discrete cosine
13:37 < fenn> realsense just does a single fixed pseudorandom dot pattern
13:37 < fenn> god i hate this new trend in websites to throw 50 layers of overlapping scrolling video
13:38 < fenn> and zero technical information

13:41 < nmz787_i> "• illuminate scene with highfrequency pattern"
13:41 < fenn> ok i can't actually find any info on how the realsense works, but that's what i think
13:43 < fenn> http://image-sensors-world.blogspot.com/2015/01/intel-releases-more-details-on-its-f200.html  "the projector emits 16 different patterns."
13:48 < nmz787_i> i think it's related to this http://groups.csail.mit.edu/graphics/CodedAperture/
13:48 < nmz787_i> .wik coded aperture
13:48 < yoleaux> "Coded Apertures or Coded-Aperture Masks are grids, gratings, or other patterns of materials opaque to various wavelengths of light. The wavelengths are usually high-energy radiation such as X-rays and gamma rays. By blocking and unblocking light in a known pattern, a coded "shadow" is cast upon a plane of detectors." — http://en.wikipedia.org/wiki/Coded_aperture
13:48 < fenn> ok i don't get this one, how does it work? "The system is able to detect and image over distances ranging from microns to kilometres dictated only by the lens. The sensor works passively and only needs ambient light." http://analog-eetimes.com/en/basf-develops-simple-3d-image-sensor.html?cmp_id=7&news_id=222906920
13:48 < fenn> "The sensor is based on a "new physical effect" enabled by the use of specially developed dye-sensitized organic light sensitive chemicals. The effect is complex and described in patent WO 2012110924 A1."
13:50 < fenn> this is a very long patent
13:54 < nmz787_i> huh, i wonder if that is related to realsense
13:54 < fenn> no
13:55 < chris_99> fenn, say it did use structured light, how would it decode it with a single sensor
14:00 < fenn> the realsense camera does use structured light with a complete basis, it turns out
14:00 < fenn> oh great, just to complicate things further: "Just to clarify, F200 is a front side camera designed for close range user interface applications. The RealSense rear camera is called R200, designed for the longer range, and based on a different technology"
14:11 < chris_99> yeah it looks like it is structured light https://software.intel.com/en-us/blogs/2015/01/26/can-your-webcam-do-this
14:13 < fenn> this page was much more informative https://software.intel.com/en-us/forums/topic/537872
14:13 < fenn> and yes, my webcam works in the dark too
14:14 < nmz787_i> hmm, so with a binocular scope you would have to opt-out of the color camera i guess
14:14 < chris_99> so objects in the scene deform the pattern, and from the deformation, you get 3D with just a single camera?
14:15 < nmz787_i> probably
14:15 < fenn> right, there is a small angle between the IR camera and the laser projector. the 3d info comes from the parallax of each "pixel" projected by the laser
14:16 < fenn> it's the same principle as an analog laser scanner, but it's done in parallel
14:16 < chris_99> a ToF camera, would simply send a single diffused beam of IR right? and then each pixel, would be able to sense photons arriving at different times?
14:17 < fenn> ToF detects phase; i'm not sure how the detector works for that
14:17 < fenn> it's modulated phase, not the actual phase of the photons
14:18 < fenn> but yes, basically
14:18 < fenn> i don't get why they don't just sell the cameras
14:18 < chris_99> which cameras?
14:18 < fenn> the realsense F200
14:18 < chris_99> you can buy it
14:19 < chris_99> i was debating buying one
14:19 < chris_99> http://click.intel.com/intel-realsense-developer-kit.html
14:19 < chris_99> $99
14:19 < fenn> maybe they are still scaling up production
14:19 < fenn> "Reservation guarantees users will receive priority to order their requested quantity of cameras when the cameras are built and ready for purchase. Plans are subject to change and Intel reserves the right to cancel camera distribution "
14:20 < chris_99> yeah you pay a dollar to reserve
14:20 < fenn> also this should have been available like 4 years ago
14:20 < chris_99> i thought it was a ToF camera :'(
14:20 < fenn> the first version "perceptual" camera was ToF but they changed it completely in the F200
14:21 < chris_99> ah
14:21 < chris_99> there is a real ToF camera thats $160 iirc
14:21 < fenn> lol "The Camera is intended solely for use by developers with the Intel® RealSense SDK for Windows solely for the purposes of developingapplications using Intel RealSense technology. The Camera may not be used for any other purpose, and may not be dismantled or in any way reverse engineered."
14:21 < fenn> yeah right
14:22 < fenn> how does the ToF camera compare for 3d scanning performance?
14:23 < chris_99> http://www.amazon.com/Creative-Gesture-Recognition-Personal-Computers/dp/B00EVWX7CG  http://www.softkinetic.com/Products/DepthSenseCameras
14:23 < chris_99> not sure
14:24 < chris_99> the res on that is lower than the structured light intel one
14:24 < chris_99> i guess Creative fabs the chips for both Intel and Softkinetic then
14:26 < chris_99> http://en.wikipedia.org/wiki/Time-of-flight_camera has a quite nice explaination
14:27 < fenn> https://forum.libcinder.org/topic/future-is-here-time-of-flight-camera-for-150-from-intel-with-sdk
14:27 < fenn> some pictures
14:28 < chris_99> cool
14:28 < fenn> heh the pupil warp looks pretty weird
14:35 < fenn> time of flight probably degrades more gracefully with movement than structured light
14:36 < chris_99> yeah
14:36 < chris_99> good point
14:36 < fenn> hmm i dont like the sound of this "Required hardware to use the peripheral 3D camera must be system with a minimum of a 4th generation Intel® Core™ processor."
14:37 < chris_99> haha
14:38 < chris_99> maybe it just shovels the raw data to the PC
14:38 < chris_99> to do the processing
14:38 < chris_99> and decodes the 3D on the host
14:39 < fenn> i doubt it
14:39 < fenn> this is a job for an asic
14:40 < fenn> but their stupid SDK might be a pig
14:40 < fenn> probably the face and hand detection is done on the computer
14:40 < chris_99> so dumb question if it's just structured light
14:40 < chris_99> why is it 640x480
14:41 < chris_99> when the camera can do 1080p
14:41 < fenn> the depth camera has to be very sensitive to light levels which means larger pixels
14:41 < chris_99> ah
14:41 < fenn> also it's high framerate which exacerbates the problem
14:42 < fenn> apparently dark objects don't show up in the depth map sometimes
14:42 < chris_99> i wonder how hard it'd be to hack your own structured light camera
14:42 < fenn> very easy it turns out
14:42 < chris_99> just using a normal webcam, stripped of IR filter
14:42 < fenn> forget about IR, just use a regular camera and projector
14:43 < chris_99> heh, you don't want to see it shining in your face though
14:43 < fenn> i dont want to 3d scan my face anyway
14:44 < fenn> <insert enormous schlong joke here>
14:44 < chris_99> heh
14:45 < fenn> the open source software for structure light that i've found so far seems kinda haphazard and incomplete
14:45 < fenn> but i haven't looked around very much yet
14:46 < fenn> i am thinking about just using a magnifying glass and computer monitor
14:46 < fenn> because projectors are annoying

14:47 < fenn> it used to be all the rage back before, well, something
14:48 < fenn> when people used CRT monitors and projectors were expensive
14:48 < chris_99> i saw a really nice HD projector
14:48 < chris_99> someone made
14:48 < chris_99> http://forum.allinbox.com/aspectgeek/Projetsencours/18/photon3k-projector-2880x1800-sujet_9774_1.htm
14:52 < fenn> yep
14:52 < fenn> i don't get why high res projectors are still so expensive
14:52 < chris_99> yeah me neither
14:52 < fenn> since even a kid can make one in their dorm room for $500
14:53 < chris_99> although the proper ones use teeny tiny DLP chips or LCDs with high PPI
14:55 < fenn> "proper" doesn't matter when you cant get even half the resolution
14:55 < fenn> besides, larger modulator is better because less diffraction
14:56 < fenn> crazy light bulbs in those things, 50,000 lumen short arc
14:57 < maaku> can someone with more bio knowledge explain this? https://medium.com/the-physics-arxiv-blog/the-origin-of-life-and-the-hidden-role-of-quantum-criticality-ca4707924552

15:01 < fenn> seems like it would be easy to add a video filter to correct for chromatic aberration

15:02 < fenn> that's not real-time tho

15:09 < chris_99> haha
15:10 < fenn> these cheap flashlight LEDs are pretty bright, possibly enough for a short throw projector

15:19 < fenn> too big
15:20 < kanzure> what was the goal again?
15:20 < fenn> 3d scanning of stuff
15:21 < fenn> chris_99: the brightness of an emitter can't be corrected by optics, so you have to start with a small emitter
15:21 < chris_99> not sure i understand what you mean, you're saying that'd be too bright?
15:23 < fenn> no, i'm saying the projected image would be blurry
15:23 < chris_99> why would it be blurry
15:23 < fenn> because the emitter is big
15:24 < fenn> you would have 100 clear images projected overlapping
15:25 < fenn> that emitter is actually 100 LEDs side by side
15:25 < chris_99> ah
15:25 < chris_99> could you put some kind of diffuser in front
15:25 < fenn> but the same principle applies to a large single LED
15:26 < fenn> you could focus it to a point and diffuse it, but i think that would lose a lot of light
15:26 < fenn> actually it wouldnt be a point, it would be a scaled down image of the emitter
15:27 < fenn> hence the arc lamps
15:31 < chris_99> gotcha
