  1. Re: Oculus rift could very well make people myopic on Virtuix Omni is a Step Toward True Virtual Reality Gaming (Video) · · Score: 1

    Your eyes "focus" at 80 feet only in the parralax sense, not in terms of the actual optics of your eye. There is no actual way to simulate different depths in this way, other than with a physical lens.

  2. Oculus rift could very well make people myopic on Virtuix Omni is a Step Toward True Virtual Reality Gaming (Video) · · Score: 1

    There is a strong correlation between time spent indoors and rates of myopia. It's not just a genetic thing that you need glasses. The only thing that's not clear is whether:
    a) eyes' ability to focus on distant objects is atrophying from lack of use, e.g. actually looking at things far away
    or b) low light levels indoors or other properties of artificial light are causing damage
    My preferred explanation is A - an eye physically changes its focus as you look at objects nearer or further. Being in one configuration all the time only looking at nearby objects basically means a lack of exercise for those muscles and it seems to follow intuitively that they would stop working as well. This kind of stuff is likely really unhealthy and I don't get why no one is talking about that... Our eyes evolved to work *outside*

  3. Re:BUNCH OF CRAP !! on Airgap-Jumping Malware May Use Ultrasonic Networking To Communicate · · Score: 1

    most DACs can actually do 96khz if they want. (so 48khz max reproducible freq.) and most humans can really only hear up to 16khz even though the "theoretical max" is 22khz. with all that bandwidth to work in, 300 baud shouldnt be hard.

  4. I think everyone is missing the point of 4k here. on 4K Ultra HD Likely To Repeat the Failure of 3D Television · · Score: 3

    It is not to have 4 times as many things on the screen as a 1080p monitor. It is to have a 2:1 pixel ratio (like all the apple retina displays) or somewhere in-between. Web content, thanks partly to apple pushing high dpi displays, is now often tuned for this, showing you twice as much detail in the same space while keeping the dimensions it would have on a normal dpi display.

    Read what anandtech had to say about testing a 4k monitor, and about how nice it is to look at fonts that arent just anti-aliased, but hardly have aliasing to begin with, thanks to the dpi.

    I run a 1440p monitor, as it was the most pixels I could reasonably afford, (4K is just too much $) and I scale everything up so it's roughly 1080p sized. I love it for the clarity and sharpness, not for the number of things I can cram on the screen. (Although I do run my font just a little small in my text editor/ide)

    There are of course downsides besides the price. Most of the 1440p monitors have poor input latency, meaning your mouse might feel a tiny bit laggy or put you at a slight disadvantage if you're a gamer, compared to lower latency 1080p monitors. That's totally ignoring whether your video card can render smoothly at that resolution. With 4K I'm not sure but I suspect it's the same or worse.

  5. And what of these $20 9W LEDs I've been using? on $60 Light Bulb Debuts On Earth Day · · Score: 1

    Yeah, there are many cheaper ones already out there... I ordered several "G7 Power" chinese 9w LED bulbs, easily brighter than the 65w incandescent floods they replaced. Look them up on amazon. They are cool to the touch and very bright, and have a "lifetime guarantee". Why have these things not gotten more press?? Are they doomed to fail in a short amount of time?

  18. Evolutionary pressure on Multitasking Considered Detrimental · · Score: 2

    The demand of modern life is that people be able to handle tasks in unison, to micromanage their thought processes, and so to some extent I think this will be selected for.
    Just as the road to increased productivity from CPUs calls for further parallelization, so does the refinement of the human mind.
    and maybe it's a case of one or the other --increasing the ability to balance multiple tasks decreases a persons ability to work effectively on a single one.

  23. The irony of my bio prof... on Wikipedia Breeds Unwitting Trust (Says IT Professor) · · Score: 2, Interesting

    She recently got her PhD and started teaching a large (~200 students) year long sequence of courses in general biology. She, as many academics do, insists that wikipedia shouldn't be used as a source of information mainly because it's unreliable.

    Over the past year she's spread more misinformation and misguided more people than any wikipedia article, mainly because of "blind trust" on the part of the students. When she doesn't know the answer to a question, she puts on her thoughtful face and just makes something up or takes a guess to maintain her appearance as an expert.

    Not everyone eats the BS. She's been corrected a couple of times by students that could cite reliable sources for their own information and she doesn't take it gracefully.
