Apple patent pokes at holographic iPhone screen

dbhh

Research

I researched and created computer generated holograms at university 14 years ago. Many others before and since have advanced this field.

There is a whole Wikipedia article about it, full of prior art http://en.wikipedia.org/wiki/Computer-generated_holography

And Apple can fucking patent it? I give up.

Enterprising French chap cranks up €100k 'flying car'

dbhh

It's been done

Parajet, a British company, did this ages ago. They did a 6000km 42 day test flight in the first prototype. It looks better than this French thing too. An added bonus: 0-62mph in 4.3 seconds on the ground!

3D printing: 'Third industrial revolution' or a load of old cobblers?

dbhh

There are already at least two 3D printers that I know of that can create PCBs, but they do it a different way. They can do everything any other extrusion 3D printer can do, but the mechanism can be fitted with a Dremel-type cutter, which is used to etch a standard PCB blank - and can also mill wood, plastic, aluminium etc. like a conventional CNC, and can be used to engrave.

My money is on this type of device - I'll dub it the "Personal Fabricator" - being the winner for home use; a combination of additive and subtractive manufacturing. Very excited about this!

BBC abandons 3D TV, cites 'disappointing' results

dbhh

Huh? The BBC broadcasts in 3d?

Kim Shillinglaw should be fired. I have a 3D TV, and enjoy the 3D effect immensely (I'm one of those people that it just really 'works' for).

I had absolutely no idea that the BBC had broadcast anything in 3D, until I saw this story. And just now, I've tried to find any information on what 3D programming might be coming up... can't find any information at all.

On that background if, as reported, 50% of people with a 3D TV watched the Olympic opening ceremony in 3D (remembering that this is the kind of programme that many people would have watched in large groups, not conducive to 3D because of lack of glasses) then actually I would come to a different conclusion:

There is demand for 3D TV, but no-one knows it's there. Kim Shillinglaw has simply not done her job.

My wife and I would absolutely have watched the ceremony in 3D on our TV, but we had absolutely no idea that it was available, or how to access it if it was. Is it a different channel or something?

Japan's rare earth discovery bad news for China's monopoly plans

dbhh
Thumb Down

Re: China only has a monopoly on willingness to pollute

"The killer here was that China glutted the market, forcing prices down and driving everyone else out of business. Then, once they had the monopoly, they put in the export restrictions."

THIS is actually what is happening across the entire manufacturing economy. China is weaning us off our own manufacturing and decimating our capability and capacity by providing unrealistically cheap products that consumers cannot refuse. However, in the next 10 years, I predict that the relative price of everything produced in China will increase between two- and fourfold - think about it, why WOULDN'T they increase their prices when they are operating a near monopoly on worldwide manufacturing? Then we'll be screwed. And we're letting it happen, right under our noses!

Review: Sony Xperia Z

dbhh
Stop

Avoid - screen scratches very easily

Sony really screwed up with the screen on this phone. Even though I keep mine fully protected in a book case, the screen is already scratched just from normal use - my phone is a week old.

It's the anti-shatter layer on the screen that's really soft and scratches easily. Sony do include additional screen protectors in the package, but nowhere does it say these need to be installed even if you're using a case for your phone. At the very least, these should be factory installed, as they are clearly a necessary part of the phone. I tried to install these screen protectors at home and screwed it up as I'd not done it before; I bought more and dust got under the front one, looked terrible so I had to take it off.

I liked EVERYTHING else about this phone - but I feel really let down that Sony didn't use Corning Gorilla Glass, like the competition. It's a big enough negative that I wish I had't bought it - it looks bad after a week, it will look terrible after a year. Conversely my 18 month old Xoom tablet is still pristine, despite being regularly prodded and swiped by my two-year-old daughter, and my three year old HTC Desire's screen is also still perfect.

Re: Still got a lot of my original gear

That's MIDI Active Sensing data - see http://www.planetoftunes.com/sequence/activesense.html

Basically it's your DX7 saying "here I am"

No GPS in the iPad Mini Wi-Fi: People are right to criticise

dbhh

Why would anyone have a 3G tablet at all??

I've never understood why anyone would want a 3G tablet at all... doesn't everyone have a phone with a 3G data connection about their person already? Why on *earth* would I want to pay much more for the 3G version of the tablet, buy another SIM and pay for another data plan!?!?

I have a WiFi Xoom (which has GPS), use my HTC Desire as a personal WiFi hotspot... and couldn't imagine any other sensible way of doing it...

Is it really just me that does this?
