Combining Two Kinects To Make Better 3D Video 106

suraj.sun sends this quote from Engadget about improving the Kinect 3D video recordings we discussed recently: "[Oliver Kreylos is] blowing minds and demonstrating that two Kinects can be paired and their output meshed — one basically filling in the gaps of the other. He found that the two do create some interference, the dotted IR pattern of one causing some holes and blotches in the other, but when the two are combined they basically help each other out and the results are quite impressive."

Earth's Water Didn't Come From Outer Space 181

sciencehabit writes "Where did Earth's oceans come from? Astronomers have long contended that icy comets and asteroids delivered the water for them during an epoch of heavy bombardment that ended about 3.9 billion years ago. But a new study suggests that Earth supplied its own water, leaching it from the rocks that formed the planet. The finding may help explain why life on Earth appeared so early, and it may indicate that other rocky worlds are also awash in vast seas."

Comment In other news, ISPs cannot do math. (Score 1) 276

If you read the ars technica coverage on this story, that same ISP offers connections up to 100mbps. If 100mb/sec is 12.5 Megabyte/second, and there's 86,400 seconds in a day, that's a little over 1TB a day. So if that customer has the top tier, let the bandwidth go full boar for less than three days, then disconnected it for the rest of the month, he could get just under 3TB. They should put more realistic constraints to their resources. This guy used less than 10% of what was possible (full bandwidth 24/7), if he's at the top tier. Granted, I understand the ISPs point of view. This is excessive. But their service offering was a factor. Why sell it then act surprised because it was used?

Comment Crappy Soundsystem (Score 1) 499

A few years ago I purchased a simple sound system, (actually I believe I got it for free when I purchased something else like a TV), and it was a Panasonic. It didn't come with rear speakers, but they had these wireless rear speakers, so I bought them a few months afterward. These were 2.4 ghz as well, but they interfered with the wireless upstairs something horrible. We would sit down to watch TV (you know, like prime time, 8pm-10pm) and turn on the sound system, and it would kill our wifi access instantly. The worse part about the system is that it scanned channels automatically and picked one which wasn't being used. I live in a suburban area, and you can see 10-20 SSIDs from my house. Needless to say there are not many channel "holes". Perhaps one of your neighbors has a similar setup? I've since bought a new sound system complete with wired rear speakers.

Comment Public Place? (Score 1) 175

I'm all for privacy, don't get me wrong. But is the Internet a public place? I mean, if I go out to lunch somewhere with my wife or a friend, anyone can take pictures of me. People can see what I'm wearing. They can overhear my conversations, and maybe glean my name or address from them. They can look at my car and my license plate. A whole slew of valuable personal information about me can be gathered from something as simple as a lunch date. Someone can follow me. Anything can happen, really. Is being on the internet any different? Just because it happens while you're at home, behind a computer, you're accessing the public world from the privacy of your own home. Is there something in the human brain that wants to pretend they're in a private space when they're not? (Think people in their cars). Just because it's virtual and not tangible, doesn't mean it isn't public. Your "address" on the internet is a public space, even if you don't like it. Just like the address of your house is public. My point is this. Your picture of your aunt Sue in your "Pictures" directory on your computer is private information. Chances are noone has that same image in that same spot, named exactly the same thing. Your IP address, what browser you use or sites you've visited is not private information. It's generic information. Some person uses Firefox. And Ubuntu. And they went to XYZ.com and their ISP is ABC corp. I'm glad the EFF is a watchdog group keeping an eye on these things. But sometimes I'm just a normal guy doing normal things and if I told you everything I did and where I went, you'd be bored to tears.

Comment Why not both? (Score 1) 405

I'm currently running Slackware64 13.0, and have been a huge Slack fan since around 3.3. Currently I run a handful of vm's under kvm. Including ubuntu, debian, centos, vista, xp, a few Win7's (two betas, rc1 and the final enterprise), opensolaris and now I'm thinking of freebsd 8.0. Some of my favorites are ubuntu and Win7. I have about 16 of them all told but only use abour 2-3 at a time. It's a fantastic way to learn several different things at once. Run two VMs, focus on OpenSolaris for a week/month then switch to FreeBSD 8.0. Then run them both at the same time when you're comfortable.
