Microsoft Research Brings Kinect-Style Depth Perception to Ordinary Cameras

ab8ten Re:Doesn't the kinect use an ordinary camera? (31 comments)

That's how the Kinect 1 works. It projects structured light and then reconstructs the world based on deviations from the expected pattern. It's built from off-the-shelf parts. The Kinect 2 measures the time it takes for an emitted laser light to be reflected back to the sensor. It's much more accurate and reliable, but requires purpose-made sensors, thus increasing the cost. Here's a good article with technical descriptions of the two methods: http://www.gamasutra.com/blogs...

"World's Most Relaxing Music" Composed

ab8ten "Research" (239 comments)

"The study - commissioned by bubble bath and shower gel firm Radox Spa - found the song was even more relaxing than a massage, walk or cup of tea."

The sort of sponsored bollocks that passes for science reporting in the Daily Mail makes the front page of Slashdot. I know the front page of Slashdot isn't run by the world's most incisive editing team, but come on!

Is Science Just a Matter of Faith?

ab8ten Science does require faith (1486 comments)

But it also requires doubt.

That's what makes it special.

Google Engineer Decries Complexity of Java, C++

ab8ten This is an ongoing trend (878 comments)

This is just a symptom of the trend for programming languages to be as abstracted as the apailable computing power allows? Computers are now powerful enough for programming to be done entirely without the use of lines of code. Just like the generational changes from assembler to compiled code to interpreted code, the next jump will be to a programming method that requires even less technical skill. Maybe. We'll see soon, i hope!

NASA Hedges Their Bets On Return To Moon

ab8ten Re:Oh please (205 comments)

Well, then we're not going anywhere. NASA cannot *afford* a Saturn V class vehicle with its current budget. That budget is not going to increase any time soon. Therefore, we have to get the best for our money. That means Shuttle-C or DIRECT. Ares 5 is just too big for the infrastructure we have.

A Widescreen Laser Projector In Your Pocket

ab8ten Re:Can somebody explain how it works? (189 comments)

Laser projector? How can you project a raster image using a inherently vector system?

I don't get it. How does it know how big the pixels should be?

(Or maybe it's obvious and I just need a beating with the clue stick here)

The light from the three RGB lasers is scanned in rows just like the electron beam in a CRT. To sweep the angle, a tiny mirror flexes very fast. The technical challenge for these projectors has been switching the mirror fast enough and getting decent performance from miniature red green and blue lasers. I think the blue one was the tough nut to crack.

UK Company Sold Workers' Secret Data

ab8ten This is an old, old blacklist (122 comments)

This blacklist was specifically for the construction industry - for those who haven't RTFA. The terrible thing is that this list, and its sale for money, has been around for years and years. It's the industry's dirty little secret. It's only now they've computerised the records that they can use the Data Protection Act to prosecute. Sadly, I have no doubt that the information will live on somehow. All the major players have fingers in the pie and won't give it up, I think.

Does Obama Have a Problem At NASA?

ab8ten Re:These aren't the rockets you're looking for... (479 comments)

Which is incredibly wasteful. As I mentioned previously, it's like using a semi with the trailer unhitched to drive to the store. You can do it, but you might as well be burning money.

Except that the J120 is only used for Orion-only missions. ie. to the ISS. And there will be so few of those missions, that the savings you make on development and infrastructure for Ares 1 actually make the J120 the cheaper option. The DIRECT architecture is all about the J232. And 2 of those are cheaper than an Ares1 and an Ares5.
