https://lwn.net/Articles/39589... we've been talking about this for a while. until FOSS can perform a task soup-to-nuts, proprietary software will control the market. once toy have a toolset that can perform in lockstep with commercial software, then you might see a change in the tide.

Yeah, a bunch of us here on Slashdot moved much of the conversation to Twitter. Unfortunately, Trump seems to get a bunch of the bandwidth there too.

3D reconstruction can be generated from 2d images: http://cvl-demos.cs.nott.ac.uk...

Totally understood. The trick is: you can tune your own signal/noise. Its very handy and I get essentially all my news via Twitter these days.

Its all on Twitter man...

Whut up, yo? Mostly moved to Twitter... You have an account... why don't I see you there much?

full color printing, or multicolor printing? i suspect that this printer is multicolor. and i call bullshit
color printing(ink on paper) has been around for centuries, but was a selective process, applying color to discreet areas(initial caps, image insert pages). and it was a costly and time consuming process. true full color printing which was reporoducable at scale was when chromolithography and color separation process was refined. it was the advances of the halftone screening process that really propelled color printing to enter the mainstream.

3d printing is more complex the its flatland brother, since halftone color process might not be a viable solution to rendering color hues(maybe with multiple hotends). 3d printing is also complicated by the fact that your printing substrate is the "ink" you are using. i've been mulling over 3d printing in color, and my opinion is 6-7 colored filaments, not 5. CMYK+white for color spectrum mixing, grey(cause it's cheaper and faster than mixing expensive pigments) to also be used for infill, and a brittle rafting material.

i know this might be a cross-grain recommendation on /., but many of the the edutainment apps for ios are great.
i purchased a couple of apps by peapod labs for my 4 year old daughter, and she can go for over an hour at a time exploring, reading singing and spelling with these apps. there are other good apps out there, try avoid the in-app purchase apps as they tend to be more entertainment and less education.

aside from tuxpaint, IMHO the best cross platform releases i've seen are the various humble bundle releases( goo, braid, etc). some of these title might be a bit mature for game playing for a 3/4 year old, but it might be a toddler and parent bonding experience smearing baddies on the screen together.

we also balance computer/tablet time with meatspace activities: reading, playing, cooking,.chores(ok cooking and chores are a bit challenging, but we try to gamify them for higher acceptance).

i live in chicago and have been bike commuting on and off for over 15 years, and i've notice the number of bike commuters increase dramatically in the last 2 years. most of the riders i see wear helmets, even the hipster fixies from wicker park and logan square.

unless you're riding on the lake front path for leisure, commuters riding on the streets should consider wearing helmets to protect themselves from head-and-vehicle or head-and-pavement impacts.

Check into it and ask about the impact of retinal remodeling on potential interventions.

Nossir. That is not correct. See my comment just above.

Yes. Precisely.

[sigh].... do not feed the troll.... do not feed the troll...

OK, I'll feed the troll. Yes, I am acutely aware of Paul Bach-y-Rita's work. You however apparently do not understand the concepts that you are invoking. There is plasticity in neural systems, yes. Plasticity is important in vision, sure. Nobody, *anywhere* has demonstrated that they can generate coherent "visual percepts" in a coordinated fashion with any kind of stimulus. Its far more complicated than hooking up electrodes and stimulating until someone "learns" what the stimulus means.

btw, the tongue thing is very, very cool. Its not vision and does not even map to vision, but those lingual electrodes can easily map topographic data, sonar data, relief data, contrast data onto the high resolution innervation of the tongue and allow people to interpret those stimulii as a map to be followed. The technology was originally developed for US Navy SEALS to navigate complex 3D environments at night, with no light and it works. It works incredibly well with very little training necessary. I would like to see more effort and funds put into techniques like that to help people live more independent lives.
