sorry for the redundant posts - I was having a hard time with the mobile site.

Oh, well now I sorta want one.

I'm ashamed it never occurred to me they would have lenses like that. Or that I didn't bother to read how they worked before assuming you'd be focusing a few inches from your face...

It is believed that the relationship is causal, meaning that spending too much time indoors is creating myopia, not the other way around. Do some googling with search terms like "Asian myopia indoors"

http://m.scmp.com/news/world/article/1334213/scientists-blame-surging-asian-myopia-rates-too-much-time-spent-indoors The relationship is believed to be causal in the direction I implied.

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.

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*

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.

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.

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?

What's up, Roku employee?

This sounds like it's fundamentally the same as radar or sonar but using light instead.

Yes, there were cases reported years ago of people "re-sharing" paid wireless connections as free ones in places like airports, for the purpose of capturing sensitive data.

a word we knew and loved, which had something to do with ecology.
